Title: Phenolic resin, porous elastic grindstone
Inventor: OGIWARA MASAAKI
IPC: B24D3/00
Filed: 1986-03-06
Abstract: PURPOSE:To aim at improvement in waterproof and heat resistance, by setting a component ratio of a phenol class and an aldehyde class to a range of 1:1.5-3.0, while mixing a foaming agent, a foam-shaping agent, an acid hardening agent and abrasive grain in resol type phenolic resin of the specified viscosity, and foaming and hardening them. CONSTITUTION:Phenol, formalin and caustic soda as a catalyzer are charged into a four-neck flask, making them react and, after being neutralized with sulfuric acid, they are dehydrated, thus resol type phenolic resin is secured. Silicon carbide as an abrasive grain, a foaming agent, a foam-shaping agent, an acid hardening agent are all added to this resin and, after being mixed, this mixture is poured into an iron frame, foaming and hardening it, thus a porous elastic grindstone is formed up.

Title: Scanning electron microscope
Inventor: MORIWAKI HIRONOBU
IPC: H01J37/28
Filed: 1980-04-10
Abstract: PURPOSE:To improve signal noise (S/N) ratio of a picture with its single exposure without causing deterioration of fine information in a microscope, by adding a signal obtained from a horizontally scanning action immediately before each horizontally scanning action to a signal obtained from said each horizontally scanning action. CONSTITUTION:If a selector switch 10 is connected to the side of a terminal (a), the scanned image observation mode can be obtained. When photographing work is performed to select the switch 10 to the side of a terminal (b), a signal corresponding to a horizontally scanning line immediately before each horizontally scanning line is added to a signal corresponding to said each horizontally scanning line because a delay circuit 12 and adder circuit 11 are in operation, and its added signal is fed to a cathode-ray tube 7. Accordingly, a same image as that obtained from double exposure can be displayed on the cathode-ray tube 7 to improve signal noise (S/N) ratio of a picture.

Abstract: PURPOSE:To rationalize the production of the titled vibrating member with the improvement of the characteristics, by unifying a cone part to radiate the sound and a bobbin part to mount a voice coil by means of a sheet of synthetic resin and forming the voice coil with the film making technique. CONSTITUTION:For a vibrating member 14 for speaker, an edge 14a, a bobbin part 14b and a cone part 14c are formed into a body by means of a sheet of synthetic resin such as an aromatic polyester polyarylate film, etc. A voice coil 19 is formed on the part 14b by the vapor deposition of the chemical plating, and then a film of a desired shape is formed by the etching process, the mask vapor deposite or the mask plating method. The terminal of the coil 19 is drawn out to a part of the part 14c and then connected electrically to an external input terminal 8b attached to a frame 8 via a lead wire. In such way, both the number of processes and the time of production can be reduced. And the speaker efficiency is increased owing to use of a light-weight voice coil.

Title: Semiconductor device
Inventor: YAGISAWA TORU
IPC: H01L23/50
Filed: 1993-03-09
Abstract: PURPOSE:To provide a semiconductor device manufacturing technique capable of high density mounting of large chips, by improving the position precision of a lead frame at the time of wire bonding, in a semiconductor device of COL structure constituted by forming a step-difference between a chip mounting part and a wire bonding point. CONSTITUTION:In a semiconductor device wherein a step-difference is formed between a semiconductor chip mounting part 2c and a wire bonding point 2d, a notch 2b is formed on the lower surface of a bend part 2a of an inner lead which forms the step-difference part. Since the notch is formed on the lower surface of the bend part of the inner lead, a circular arc shape part is not formed on the lower surface of the bend part. Thereby the position precision of a lead frame on a heating frame is improved at the time of wire bonding, and imperfect wire bonding can be prevented. The inclination of the step- difference part can be increased, so that the distance between a chip and the step-difference part a heating frame can be reduced. Hence large chips can be mounted with high density.

Abstract: PURPOSE:To offer the programmable controller which realize a speedy NOP process. CONSTITUTION:A flip-flop 205 is provided between write signal lines 209-2 and 209-3 connecting an arithmetic processor 201 and a data memory 202.

IPC: F41B6/00
Filed: 1989-02-28
Abstract: PURPOSE: To suppress generation of parasitic arc by providing first and second conductive current feed rails arranged contiguously to respective launcher guide rails while being connected electrically therewith at the muzzle such that the flux is coupled substantially the guide rail. CONSTITUTION: When a switch 48 is closed, a current flow from a current feed rail 36 through a launcher guide rail 30 to a fuse 53 which is thereby blown out to generate an arc or plasma thus driving the bottom plate of a projectile and a launcher 52 along the rails 30, 31. Since no current flow through the back side of the rails 30, 31, i.e., between B and C, voltage drop across a resistor can be eliminated. Since contribution of ohmic voltage drop to the voltage between the rails 30, 31 is zero, possibility of arc regeneration arc due to parasitic capacity can be suppressed significantly between B and C after passing the launcher 52.
