Patent JP-S63293946-A (JP)
Title: Manufacture of semiconductor device
Inventor: SHINOHARA SHOHEI
IPC: H01L21/28
Filed: 1987-05-27
Abstract: PURPOSE:To make the margin for mask alignment unnecessary, by forming a step-difference having a sidewall which is parallel with an isolation boundary and has a specified inclination angle against a substrate surface, and protruding toward a dielectric isolation region side, depositing an interlayer insulating film on the step-difference, and then anisotropically etching a contact hole. CONSTITUTION:In the vicinity of an isolation boundary neighboring with a portion where a contact hole 6 to a diffusion layer 4 is to be formed, a pattern of gate material, e.g., polysilicon 8 is formed. A sidewall spacer is formed by anisotropic etching after a CVD SiO2 film, e.g., is deposited. By this working process, a sidewall spacer 9 is formed, also on the side surface of the polysilicon pattern 8 in the vicinity of the isolation boundary. As the spacer is formed by anisotropic etching, its side surface 9a has an inclination angle theta larger than or equal to 60 deg.. The contact hole 6 is formed by anisotropic etching such as reactive ion etching applying, e.g., CHF3 gas. In this process, a second sidewall 10 of the interlayer insulating film material is formed also on the side surface of the sidewall spacer 9.

Title: Pressure increasing method of adsorption tower in three-tower pressure swinging method
Inventor: NAKAMURA MASAAKI
IPC: B01D53/04
Filed: 1983-07-18
Abstract: PURPOSE:To increase the recovery of the product gas in a three-tower pressure swinging method by separating a pressure reducing stage into two stages, a pressure equalizing and a pressure releasing stage, and utilizing a part for a pressure increasing stage. CONSTITUTION:The raw gas is introduced into an adsorption tower A by opening valves A-1 and A-5. The impurity component other than H2 is mostly adsorbed therein, and the product H2 is discharged from the top of the tower (adsorption stage). The adsorption stage is finished thereafter. Then the pressure of the tower A is reduced countercurrently by opening valves A-3 and B-3, and the off gas discharged at the initial stage is taken out from the lower part and introduced into a tower B from the lower part. The pressure of the towers A and B is equalized by this stage. The valves A-3 and B-3 are then closed and a valve A-4 is opened to reduce the pressure in the tower. The remaining impurities are desorbed, and discharged from the bottom of the tower (pressure reducing stage). Then the product H2 is introduced from the top of the tower by opening a valve A-2 to purge the inside with the product H2 (purging stage), and the adsorbent is regenerated.

IPC: G06F3/041
Filed: 1992-05-22
Abstract: PURPOSE:To prevent the generation of misdetection in the coordinates of a detection pen tip due to noise generated at the time of turning on/off a pen siwtch. CONSTITUTION:The pen switch 34 is arranged on the end part of the detection pen 31 on the opposite side of the pen tip 32 through an impedance conversion circuit 35. A detection electrode 33 can be slided in the axial direction and its sliding motion turns on/off the switch 34 through a pen switch connecting part 36.

Title: Camera capable of trimming photographing
Inventor: GOTO TETSURO
IPC: G03B27/34
Filed: 1989-05-25
Abstract: PURPOSE:To carry out photographing at a desired viewing angle without giving unpleasant feelings to others under silent circumstances by selecting motor-driven zooming or trimming photographing according to whether a silent take-up mode is set or not. CONSTITUTION:When an operation member is operated if the silent take-up mode in which a film is silently taken-up is not set, a control means 105 outputs a lens driving signal and changes the focal length of photographing lens with motor drive. On the other hand, when the operation member is operated if the silent take-up mode is set, the control means 105 outputs a trimming signal instead of the lens driving signal. A setting means 102 sets a region extending in the exposing area out of one frame of a photographed and recording medium according to the trimming signal. Then, a recording means 103 records information to show the set region on a trim recording medium. In other words, when the silent take-up mode is set, the motor-driven zooming of the photographing lens is not carried out, but the trimming photographing is carried out.

IPC: C10N40/14
Filed: 1990-05-22
Abstract: PURPOSE:To obtain an electroviscous fluid which has a large ratio of shearing stress to current density and is capable of minimizing consumption of electric power by dispersing chitosan into an electrical insulating liquid. CONSTITUTION:An electroviscous fluid prepared by dispersing chitosan into an electric insulating liquid. The chitosan used is a basic polysaccharide which comprises a large number of bonded glucosamines, obtained by deacetylating chitin, a polysaccharide comprising a large number of bonded N- acetylglucosamines, which is ordinarily obtained from the shell of a crustacean such as a crab or a lobster. This fluid has a current density of as small as about 1/100 of that of an electroviscous fluid using polysodium acrylate as a dispersing phase when the shearing stresses are equal to each other. Therefore it is possible to suppress consumption of electric power and reduce electric current. This fluid consumes less electric power than the conventional one and is useful for a clutch, a shock absorber, an engine mount, a vibrator, an electricity-to-machine interface and the like.
