Title: Etching method
Inventor: TAGAMI TAKASHI
IPC: H01L21/76
Filed: 1984-01-25
Abstract: PURPOSE:To make side etching less and to form a deep groove in high accuracy by restraining the side etching generated by dry etching with an anti-etching film formed on the side wall of an Si groove. CONSTITUTION:An etching mask 2 such as an SiO2 film or an Si3N4 film is formed on an Si substrate 1 and an Si groove 5 is formed by shallowly etching with a fluorine gas such as CF4 or SF6. The inside of the Si groove is covered with an etching resistant film and etched anisotropically to cover only the side wall of the Si groove with the etching resistant film 7. For the etching resistant film, a plasma-oxidized or deposited SiO2 film is preferably used. The process is repeated again and then the etching of Si is further carried out. The undercut can be reduced to b1 and the b1 can be made one third since the etching of Si is divided into three times.

Title: Production of silicon carbide crystal layer
Inventor: INOOKU TOSHIKI
IPC: C30B19/00
Filed: 1979-01-29
Abstract: PURPOSE: To perform the title production while controlling the SiC crystal form, the layer thickness, etc. by melting an Si substrate provided with a formed SiC layer on a sample stand having an SiC surface layer and holding the temp. of the latter SiC layer higher than that of the former.  
     CONSTITUTION: On Si substrate 2 SiC primary layer 4 is formed by vapor phase growing or other method. Substrate 2 is placed on sample stand 10 having SiC surface layer 6, and by heating stand 10 substrate 2 is melted to form Si melt 12. This state is maintained for a fixed time while holding the temp. of stand 10 higher than that of layer 4, whereby SiC secondary layer 14 is deposited on the back side of layer 4 from melt 12. It is considered that layer 6 on the stand 10 surface melts in melt 12 and deposits on lower temp. side layer 4. Because of liquid phase grown crystal, layer 14 has superior crystal perfectness compared to vapor phase grown crystal.

Title: Track type travel carriage and conveying device with track type travel carriage
Inventor: TANAKA MIKI
IPC: H01L21/68
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To suppress rises in the material cost and running cost of the conveying device by making a branch path roller abut against one external wall and changing a travel to a desired direction. SOLUTION: Once recognizing that a branch part is reached, a driving device 2 transmits the driving force of a driving motor to a rotary shaft 24 to make a branch path selection roller fixed to the rotary shaft 24 abut against the external wall 8a of a track path. A branch path selection roller 3b is provided having a 90 deg. angle of deflection from the branch path selection roller 3a. Consequently, when the branch path selection roller 3a is abutting against the external wall 8a, the roller 3b does not abut against the external wall 8b. Thus, the track type travel carriage 1 is restrained by only the external wall 8a, so it is able to travel toward a station along the external wall 8a. Consequently, even the conveying device which requires more than one branch part can be suppressed in rises of its material and running costs.

Title: Output strain compensating method for power converter
Inventor: OKUYAMA TOSHIAKI
IPC: H02P27/06
Filed: 1995-01-27
Abstract: PURPOSE: To always minimize an output voltage strain by calculating to detect the output voltage strain corresponding to each output phase and output current polarity of a converter, and so regulating the compensating amount of the output strain at each output phase and output current polarity as to allow the calculated value to approach to zero based on the calculated value. CONSTITUTION: A compensating amount calculator 8 calculates to obtain a strain component corresponding to each element (each arm) based on a strain component estimated value, and regulates the magnitude (compensating amount) of the output amounts ΔV1 *, ΔV2 * at compensators 51, 52 correspondingly to the elements in response to the components. The compensators 51, 52 form signals relative to the output current polarities, add them to a voltage command V* to cancel the voltage strain ΔV, thereby compensating the output voltage strain. Accordingly, the output voltage strain of a power converter is so automatically compensated as to become minimum at each phase and each output current polarity, thereby preventing a torque ripple and power source harmonic waves.
