Title: Manufacture of semiconductor device
Inventor: HAMANO TAKASHI
IPC: H01L21/3065
Filed: 1990-07-25
Abstract: PURPOSE:To form connection electrodes having almost the same hole diameter by forming first contact holes and second contact holes through using a second mask pattern, which selectively has openings on each of first and second wiring layers, on the surface of an insulating film. CONSTITUTION:A resist film mask pattern 4 is a pattern provided with windows in contact hole-forming parts above first wiring layer 11 and second wiring layer 12. The diameter of the window is a hole diameter almost equal to that of the contact hole expected to be formed. Then, the resist film mask pattern 4 is used as an etching prevention mask to anisotropically etch PSG film 2 expressed in the window parts to form contact holes A, B. Because both etching quantities are almost the same as film thickness 5500Angstrom , it is possible to form contact holes with equal hole diameter. Thus, the deep contact hole A is formed into a shape which can be furnished with a wiring having a good coverage while the contact hole B is shallow and requires no consideration for coverage so as to be formed with a correct hole diameter suitably and accurately.

Title: Tank body hoisting device for washing machine
Inventor: TOZAKI SO
IPC: D06F37/24
Filed: 1998-07-14
Abstract: PROBLEM TO BE SOLVED: To enable accurate prevention of the generation of an abnormal sound for a long time attributed to the deflection and return of a hoisting bar not only without causing an increase in the assembling man-hour and a rise in cost but also without being associated with difficult work in production. SOLUTION: A part 60 diametrically smaller than the diameter of a hoisting bar is formed in a piercing hole 59 of the hoisting bar possessed by an upper receiving member 51 of a hoisting mechanism for hoisting a tank body. The hoisting bar is so arranged to always contact the part to prevent the hoisting bar from hitting the inner circumference of the hole 59 of the upper receiving member 51 when it happens to be deflected or returned. This can restrict vibration of the upper receiving member 51 and, moreover, vibration of an outer case without applying any grease between the hoisting bar and the hole 59 of the upper receiving member 51 thereby preventing the generation of an abnormal sound.

Abstract: PURPOSE:To obtain nearly the same picture in a bright place as that even in a dark place by controlling a shutter open time corresponding to a level of a video signal outputted from plural TV cameras and selecting either a video signal or a synthesis signal from each camera. CONSTITUTION:A video signal from a switch 13 is inputted to a RAM 23 and controlled by a controller 24. Then the controller 24 selects a half the horizontal scanning line of a video signal from blocks 31-34 to reduce the data of each horizontal scanning line to 1/2 thereby synthesizing 4 screens into one screen. Thus, when a switch 21 is thrown to the position of a contact (e), a synthesized video signal from the RAM 23 is outputted to a CRT 22 via a D/A converter 8. On the other hand, when the switch 21 is thrown to any of contacts a-d, a video signal from any of the blocks 31-34 is outputted to the CRT 22 via the D/A converter 8. The video signal from plural TV cameras is monitored by one CRT by allowing the user to have only to select the switch 21 to the position of the RAM 23.
