Title: Vapor growth device for semiconductor substrate
Inventor: KOJIMA MASAKATSU
IPC: H01L21/205
Filed: 1978-04-21
Abstract: PURPOSE: To avoid the slip or crack and thus to ensure good vapor growth by coating the SiO 2  layer at the area where the support tool touches the fringe of the Si substrate.  
     CONSTITUTION: For support tool 13 of Si substrate 2, SiC23 of about 10 and SiO 2 33 of above 3000Å are laminated on the surface of graphite 3. With application of the vapor growth to the single crystal Si layer under such structure as mentioned above, no slip or no crack is caused at the temperature lowering time after end of the growth since no vapor growth is applied to the supporter, thus obtaining a high- quality device. Furthermore, the Si film is grown at the unwanted part to prevent the lowering the Si molecul density on the surface of the substrate.

Title: Control of current follow-up-type inverter
Inventor: OGAWA YOSHIHARU
IPC: H02M7/48
Filed: 1992-03-05
Abstract: PURPOSE:To eliminate a basic wave component of error current and to increase a current accuracy by superimposing a proportional signal to correspond to the voltage of an a.c. power system for correcting a current deviation and by using the corrected current deviation in the PWM control. CONSTITUTION:Using the voltage of a voltage-type inverter 1 at a connection between the converter and an a.c. power system which is detected by a transformer 8, the voltage (VAC) of the a.c. power system is calculated. The calculated voltage is superimposed by an adding circuit 7 on a current deviation between an output current detected value I and an output current command value I'. At that time, the value K3 of the voltage VAC K3 (K3 is a coefficient) to be applied to the adding circuit 7 is so set as to meet 1-K2.K3=O (K2 is a conversion coefficient of the inverter) and the current deviation is corrected according to a proportional signal which is proportional to the voltage of the a.c. power system and then PWM control is conducted. As a result, a component which is included in the current deviation and which is a current deviation generating factor is eliminated and thereby a basic wave component of the error current can be directly eliminated. Consequently, a current accuracy in the current follow-up control can be remarkably increased.

Title: Thin battery
Inventor: HANABUSA KIYOSHI
IPC: H01M2/10
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To extract an extremely thin collector from a battery body part to use it as an outside electrode, to reduce the weight of a battery and to enhance the mechanical strength of an external terminal by catching the collector with an insulation film on both ends, where opening parts face to each other. SOLUTION: A battery body part M has a substantially rectangular thin plate-like form and is composed by sealing a laminated structure 20-24, along with an electrolyte by the use of an insulation film 4. The insulation film vertically catches an electrode terminal 30 via an adhesive 5. The electrode terminal 30 is connected to a projecting part 20 of a collector extracted from the laminated structure 20-24 of the battery body part M, and a part of the electrode terminal 30 in an opening part 6 serves as an external terminal 32. Since the opening part 6 is formed at a position which does not include a tip part 4E of an electrode extraction part H, the electrode terminal 30 is caught by the insulation film 4 at both the ends of the opening parts 6 and cannot move freely independently, and the strength of the external terminal 32 is enhanced by being locked with the insulation film 4.  Similarly, the external terminal 32 is reinforced in the width direction of the external terminal 32 and on its undersurface by means of the locking of the insulation film 4 as well.
