Abstract: PURPOSE: To obtain hexaorganoditin compound of high purity at a high yield by electrolyzing specific triorganotin formate in the presence of an organic solvent.  
     CONSTITUTION: The triorganotin formate expressed by the formula I is obtained by the dehydration reaction of triorganohydroxide or bis(triorganotin) oxide and formic acid or the desodium-halide reaction of triorganotin halide and sodium formate. This is electrolyzed in the presence of an organic solvent. The organic solvent is preferably, for example, dimethylformamide, 2-ethoxy ethanol, etc. which have no moisture content. The quantity of electricity necessary for the electrolysis is about 1W4 Faraday (equiv.) and electric efficiency is about ≥20%. The reaction is performed at room temp., and the evolution of carbonic acid gas and hydrogen is admitted during reaction progress. The product is straightly filtered if it is solid, and is fractionally distilled if liquid. This yields the hexaorganoditin compound of the formula II.

Title: Fabrication of compound semiconductor integrated circuit
Inventor: KURODA ATSUSHI
IPC: H01L21/76
Filed: 1995-06-01
Abstract: PURPOSE: To facilitate the formation of isolation trench by forming an isolation trench after implanting impurities in a compound semiconductor substrate and then subjecting the substrate to annealing. CONSTITUTION: After forming a mask 23, Si ions are implanted to form an ion implanted region 24. An endless isolation trench is then formed by dry etching in the major surface of a GaAs substrate 1. Since the annealing for activating the implanted region 24 is not performed, an etching difficut reaction film is not produced on the interface between the GaAs substrate 1 and an SiON film forming an ion implantation protective film 22. Consequently, the isolation trench 2 can be formed surely without increasing the etching power. The isolation trench 2 is then filled with the SiON film and lamp annealing is performed thus activating the implanted region 24. This method prevents etching cost increase.

Title: Pixel defect correction method in image recorder
Inventor: KIMURA TSUTOMU
IPC: B41J2/445
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To make possible to eliminate the need for an optical or mechanical additional mechanism, to prevent a time period necessary for image recording from lengthening, and to correct pixel defect by correcting the recording density so that an image signal inputted to neighboring pixels of a defective pixel which fixes a recording density near a minimum value may be increased by a prescribed value. SOLUTION: A defective pixel P0 fixes the recording density near a minimum value irrespective of the value of an image signal. When an image signal to be entered to neighboring pixels P1 , P2 , P3 , P4 is corrected so that the density recording may be increased by a prescribed value, the distribution of the transverse intensity of recording light is as shown in Fig. (3). The density distribution of a light-sensitive material exposed to recording light of the intensity distribution is as shown in Fig. (4) due to the blurring characteristics, the density distribution felt by a human being is as shown in Fig. (5) due to the blurring characteristics of vision.  It means that an average density in parts near the defective pixel P0 becomes nearly the same as when there is no defect, and a density difference between the defective pixel P0 and neighboring pixels P1 , P2 , P3 and P4 is hardly felt, it is difficult to identify visually an image defect.

Title: Control device for variable delivery pump
Inventor: KANEHARA MASAKI
IPC: F04B49/00
Filed: 1979-10-22
Abstract: PURPOSE: To improve a starting capacity of engine by minimizing load torque of a pump during engine starting.  
     CONSTITUTION: This control device consists of a control cylinder 7, a pressure generation unit 5, and a pressure control valve 8. The control cylinder 7 increases the discharge quantity of a variable delivery pump 1, when a supply pressure is increased. The pressure generation unit 5 produces a pressure P 1  responding to flow rates passing through a pipe line 4, connected to a center bypass of a shift valve 2. The pressure control valve 8 supplies the pressure P 1  to said control cylinder 7, if the pressure P 1  falls below a predetermined pressure P 0  and feeds a pressure P 2  in reverse proportion to the pressure P 1 , if said pressure P 1  exceeds the predetermined pressure P 0 . This construction brings the pressures P 1  to nought and minimizes the inclined rotation angle of a tilted plate of the pump 1. If the shift valve 2 lets the engine start under neutral conditions, however, the pressure P 1  is promptly increased to P 1  max. and the pressure P 2  is quickly reduced to P 2  min. as well. Thus the minimum discharge quantity of the pump 1 is maintained and the starting capacity of the engine improved.

Filed: 1987-05-29
Abstract: PURPOSE:To reduce the number of used parts of a disk player, by causing a pivot which is passed through one of paired tray carriers from its upper surface to its lower surface to support a chuck plate for small-diameter disk in a state where the chuck plate can move in the vertical direction. CONSTITUTION:A rod-like pivot 112 is perpendicularly provided downward on a tray carrier 80 side of the lower surface of a chuck plate 110 for small- diameter disk. The pivot 112 is loosely passed through the tray carrier 80 in a vertically movable state. Since driving devices 33 and 34 for small-diameter disk are retreated to the tray carrier 80 side when a large-diameter disk is reproduced, the pivot 112 is brought into contact and locked with the upper surface of the moving body 32 of the driving devices 33 and 34. Therefore, the chuck plate 110 for small-diameter disk does not descend and the chuck of the chuck plate 110 is not brought into contact with the large-diameter disk.
