Over years, NEPCON Japan has been gaining popularity under the organization of Reed Exhibitions Japan. Recently concluded NEPCON Nagoya Japan 2018 was held in Nagoya this September from 5th to 7th at Portmesse Nagoya, Japan. The NEPCON Nagoya exhibition with Automotive World, RoboDEX and Smart Factory Expo has special relevance in Nagoya since major factories, including Toyota, DENSO and Mitsubishi, are situated in an industrial heartland close to Nagoya in the mid area of Japan and it would be more convenient for exhibitors to market their products and exchange know-hows with other firms. The main show and three concurrent shows regarding automotive technology, AI, and smart factory open in Nagoya and automotive technology was the major highlight.

The importance of the show can be gauzed by the fact that 36281 visitors visited during three day display of research, technology and products in automotive AI and smart factory automation.

A number of knowledge Conference for future electronics and its R&D and manufacturing technology were held concurrent to the main shows. The major topics include: SMT, 5G, milliwave, power device and car electronics. A few interesting conferences captured the imagination of the audience are:

  • 5G Will Change Society – Susumu Yoshida, Chairman,5GMF, Professor Emeritus, Kyoto University.
  • The IoT Evolution Accelerates Digital Transformation – Naoki Tani, Senior Vice President, Managing Director, NTT DOCOMO, Inc.
  • Next Generation Vehicle Development Race — Its Impact on Electronics Industry – Wataru Izumiya President & CEO, Sangyo Times, Inc.
  • Technology Trend for SiC Device and Application- Junji Yamada, General Manager, Mitsubishi Electric Corp.
  • Next Generation 5G — Innovation of Boards/Materials for High-speed Transmission – Naoki Nakamura, Vice President, Fujitsu Advanced Technologies Ltd.

Though a large number of exhibitors exhibited their products and technology at the show but below are worth mentioning from the point of view of electronics contribution to automotive industry:

ROHM: The Industry’s First Noise-Tolerant Opamps

Unprecedented noise immunity contributes to improved reliability and simpler designs in automotive sensor applications. ROHM has recently announced the availability of automotive-grade ground sense opamps that deliver breakthrough EMI tolerance (noise immunity) for automotive systems using sensors along with core systems for EVs and HEVs.ROHM

Developed using 3 proprietary analog technologies (layout, processes, circuit design), the BA8290xYxx-C series features superior noise immunity that suppresses output voltage fluctuation in all frequency bands to less than ±1%, compared to ±3.5% to ±10% with conventional products. As a result, installing in the subsequent stage of devices that output micro-signals such as sensors will make it possible to amplify signals without being affected by noise, eliminating the need for noise countermeasures such as filters. This helps to reduce design load while contributing to greater reliability.

The latest automotive systems achieve greater fuel economy and safety by adopting ECUs and sensors that manage and optimize conditions such as temperature, acceleration, and current. At the same time the move towards greater digitization and application density in automotive systems has increased the amount of noise generated in the environment, presenting significant problems for sensors and other small-signal devices. What’s more, during automotive development it is extremely difficult to evaluate individual sources of noise, making it necessary to perform noise evaluation after installation. So unless careful attention is paid to noise design, major modifications (entailing increased costs and development time) may be required if the application fails testing.

In response, ROHM has developed the world’s first opamps that eliminate the effects of noise in automotive sensor applications by utilizing a vertically integrated production system that leverages analog design technology and proprietary bipolar processes.

VTOUCH: Control your device remotely by pointing at the device 

VTOUCH aims to make people control device remotely by simply pointing at the device with its world class computer vision and machine learning technologies.

Vtouch lets users control devices simply by pointing at the device with a finger. By tracking user’s eyes and finger tips with 3d camera, Vtouch system calculates where the user is exactly pointing at. Unlike existing gesture controllers, Vtouch doesn’t require any cursor on screen. User can directly select and control what they see just as touching smartphone. User can use Vtouch to control both devices with/without display and even things.

Vtouch allows people touch control devices without physically touching them by tracking user’s eyes and fingers with a 3d camera. The technology can be integrated into various fields. The technology can provide the natural way of interacting with devices and things.

Major Target market for the technology may be Automotive, Smarthome, hotel, hospital, retail shop, control room and digital signage.

Murata: High Temperature Film Capacitor for Automotive

The Murata High Temperature Film Capacitor (FH series) can be used for continuous operation at temperatures of 125°C.The capacitor is provided with a self-healing function for use in that high temperature range. Therefore, it is optimal for the converters and motor-drive inverters of eco-friendly cars that require a high temperature guarantee.

Performance: The FH series uses materials with high heat resistance. Therefore, it has a higher allowable ripple current under higher temperature environment than conventional PP film capacitor. This feature is more prominent in the high frequency range. For example, when the ambient temperature is at 105°C, PP film capacitor would be already on its limit for allowable ripple current, but because of the higher heat resistance of FH series, the allowable ripple current can be increased drastically.
