英文要約1. The contents of research and development and achievements, etc.

Currently, devices that advance the prototype development are assumed to inverter case installed around the engine. Currently, lighter cases have been manufactured by aluminum die-casting, space saving, consider resinification to cost reduction.

A reduction in the deterioration and material strength of the thermal conductivity due to the material change to satisfy the function compensate by design method using topology optimization to achieve the resin of is. It performed prototyping in various resin material using a mold for molding the prototype of the inverter case fabricated previous year were investigated resin material comprising a base.
Resin of the material strength and the price surface selected resin material PC-ABC from, ABS, performs a prototype molded at PA, examined the functions, such as heat resistance and strength required for the inverter case.
Prototype of a high temperature molding using the oil temperature controller was also carried out in order to mold a high strength.

Functions required for the inverter case, the base material from the adhesion of the plating to select the PC-ABC, thereafter it was decided to proceed with prototyping using PC-ABC.
We are using the laser ablation process in this study in order to perform a designed pattern on the surface of the device. To confirm that it is processed into an arbitrary shape, was mapped laser processing patterns of the plane was designed for testing processed into three-dimensional shape.
When mapping a planar three-dimensional shape, well pattern in the stereoscopic and plane was found that sites that are not connected arises. In Fig.2 is a vicinity of the side surface of the hole shape shown in red.

The primary plating nickel-plated since plating the resin, the thermal conductivity than nickel given the heat transfer degree secondary plating at high metal required. Result of examining the aluminum and copper, was adopted copper stranded cost.
Secondary plating result of applying the adopted thickness plated with copper, to resolve the gap is filled problem in adjusting the relationship between the heat transfer portion and the gap because the gap is filled problem occurs secondary plating in the secondary plating. In addition the site indicated by the red circle of Fig.9 is this at the site of the primary plating is set to leave the island will be solved by improving the algorithm of calculation.
Currently, advanced fabrication of the case sample having been subjected to copper thickness plated with the result of improved algorithms.

2. Development of ultra-precision molding method

Because of that to control the electromagnetic waves or light to later this year in the field of view, has been predicted that in the future, the higher the resolution of the pattern. Since the function with an accuracy deterioration when also transferring it as could high-definition processed into molds, jigs no expression is predicted, we for prototype parts obtained by adding a meta surfaces fabricated last year pressure sensors in the injection mold, add the temperature sensor, to evaluate the difference of behavior in the repeatability and the molding machine and the mold of the injection molding.
Baratsuki molding machine, it could be confirmed variation of the molding material, it is believed to be necessary to develop the precisely shaped to mold and molding techniques using these devices and materials.
