Title: Boride-based ceramic composite material and production thereof
Inventor: UEDA HISAO
IPC: C04B35/58
Filed: 1994-02-16
Abstract: PURPOSE:To obtain the composite material with both high mechanical strength and toughness, excellent in high-temperature characteristics and the resistance to welding with aluminum alloys. CONSTITUTION:This composite material is so designed that 3-30vol.% of SiC <=500nm in particle diameter and 5-10vol% of Co, Ni and/or Ti metallic powder are dispersed in the inside or boundary of the crystal grains 0.3-5mum in average particle diameter of the matrix of a boride of one element selected from groups 4a and 6a elements. This composite material can be obtained by molding a mixture of a boride, SiC and metallic powder followed by sintering in a vacuum or inert atmosphere at >=1300 deg.C. By this method, the composite material has such a special texture that SiC fine particles and the metallic powder each of nano size have been dispersed in the boride matrix, being significantly high in breaking strength and breaking toughness, etc. In cutting aluminum alloys, this composite material has cutting characteristics better than those of carbide alloys, being more inexpensive than diamond sintered compacts. Even in the case of a jig material for producing aluminum cans, this composite material is lighter than carbide alloys and presents high durability compared to them.

Title: Field effect transistor amplifier
Inventor: OOI KAZUNARI
IPC: H03F3/345
Filed: 1978-02-24
Abstract: PURPOSE:To make power consumption low by lowering the power source voltage without lowering gm of a FET and a load impedance by connecting the constant current source of an active or passive circufit to the FET to supply a prescribed drain current. CONSTITUTION:Constant current circuit 25 is connected to the drain of FET 21, and drain current ID near to zero gate bias drain current IDSS is flowed to hold gm of FET 21 largely. Simultaneously, the current flowing to load circuit 23 is made small. As a result, the voltage drop in load circuit 23 can be made small; and consequently, even if the impedance value of load 23 is set to a large one as conventional, power source 22 can set the supply voltage low without lowering the gain in comparison with a conventional one, so that power consumption can be made low.

Abstract: PURPOSE:To suppress the generation of dioxine before it is generated by providing more than three air supply nozzles at the circumferential wall of a secondary combustion chamber and supplying secondary air toward the contact point with a horizontal, imaginary circle in the room. CONSTITUTION:Four secondary-air supply nozzles 10, for instance, are provided at the circumferential wall 2a of the secondary combustion chamber 2 of a garbage incinerator with the blow-out holes at their tip ends pointing in the direction of the tangential line to a horizontal, imaginary circle C, and the ends of the secondary air supply nozzles 10 are respectively located on the four sides of a horizontal imaginary square S with its center at the center of the circle C. Supposing that the length of one side of the horizontal, imaginary square S is L and the diameter of the horizontal, imaginary circle C is D, the value L/D is preferably 5 - 15. With this constitution the combustion gas and the secondary air are mixed ideally and secondary combustion is made with an improved secondary combustion efficiency and the proportion of unburned garbage is much reduced. Accordingly the amount of matters that are contained in the unburned garbage and are precedent to dioxine is also reduced a great deal, and the exhaust gas that does not contain dioxine is discharged to the atmosphere. Furthermore, since the proportion of unburned dusts is reduced, the generation of NOx is also repressed.
