Filed: 1994-02-15
Abstract: PURPOSE:To obtain a silicon nitride-based composite ceramic having high tenacity by mixing silicon nitride powder and a sintering assistant with a specific metallic powder, making the mixture into specific flat plates, molding the flat plates, and sintering the molded article to react the metallic powder with the silicon nitride. CONSTITUTION:Silicon nitride powder and a sintering assistant are compounded with metallic powder of at least one kind selected from Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, Al and their alloys. These are mixed with a ball mill, etc. This mixture is made into flat plates having d/t>4 where (d) is the minimum diameter of the flat plates and (t) is their thicknesses. These flat plates are molded and sintered at 1500-2000 deg.C. The metallic powder reacts with silicon nitride and is led into its nitride and silicide. This process works to produce a silicon nitride-based composite ceramic having a strengthened phase consisting of the metallic nitride and silicide and having flat shapes in which the minimum diameter (d) and the depth (t) have the relation of d/t>4.

Title: Engine driven-type compressor
Inventor: SUMIYA NAOKI
IPC: F04B49/02
Filed: 1980-03-29
Abstract: PURPOSE: To make it possible to save the fuel by performing an automatic and nonload operation of an engine, when an outlet hydraulic pressure comes to a specified setting pressure and a compressor is put in nonload operation.  
     CONSTITUTION: When a regulator handle 41 for a fuel supply system 40 is turned to operation position, a compressed fluid is stored under pressure in an air tank 8 by a reciprocating motion of a piston 3. When the hydraulic pressure reaches a specified pressure, a primary pressure control valve 14 opens and the compressed fluid is fed into a cylinder 10 through a passage 17C, outlet 19, and piping 25 and 26. When a piston 11 and a rod 12 are then pushed down by the compressed fluid, a suction valve 4 is opened and a compressor 1 is brought into a nonload operation. At the same time, the compressed fluid is supplied to the secondary pressure control valve 28 from the outlet 19 through piping 25 and 27 and opens the pressure control valve 28 thereby feeding the compressed air to a cylinder 30A. The compressed air displaces a piston 32 to the left in the figure, and pushes a support plate 37 and a wire 36 and turns a handle 41 from operation position to starting position, thereby limitting the supply of fuel. As a result, the number of revolution of engine is reduced and the fuel is saved in proportion to the reduced number of revolution.

Abstract: PURPOSE:To input data on a coordinate input tablet with a normal pen and a finger by generating a signal by a trigger signal generating part when trigger pressure exceeds a set value or when variation in the trigger pressure exceeds a set value. CONSTITUTION:When the top surface of a resistance film 1 is pressed with a finger, etc., at normal pressure, a conductive film 5 and the resistance film 1 become conductive to each other at the time of the depression.
