Title: Semiinsulating gaas single crystal and manufacture thereof
Inventor: MIZUNIWA SEIJI
IPC: C30B11/00
Filed: 1989-12-14
Abstract: PURPOSE:To make the fine processing feasible by a method wherein an ingot or a wafer is heat-treated at specific temperature while the numbers of fine ruggedness exceeding specific scattered sectional space exposed in the wafer surface are limited. CONSTITUTION:Cr doped GaAs single crystal ingot manufactured using horizontal boating process or a wafer manufactured by cutting out the ingot is heat- treated at the temperature of 1050 deg.C-1200 deg.C to solid solve Cr once in crystalline state. Later, the temperature is lowered starting from the heat treatment temperature down to 800 deg.C at the rate of 50 deg.C/h-160 deg.C/h. Through these procedures, the concentration distribution of Cr can be equalized making the separation thereof minute so that the numbers of fine ruggedness in scattered sectional space >=0.06mum<2> exposed in the wafer surface after mirror grinding process may not exceed 50 each to make the fine processing feasible.

Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a hood which brings out a sufficient resistant force at a fixed position (closed condition) of the hood, against the force in collision of a vehicle at the front face thereof and effectively absorbs the collision energy. SOLUTION: A hood hinge 1 is constituted of a hinge bracket 2 attached to the vehicle body 10, a lever 3 whose rear part is pivotted by a shaft 5 in the hinge bracket 2, and a hinge arm 4 pivotted by a shaft 6 at the front part of the lever 3 and fitted to the rear part of the hood. The shaft 7 fixed to the hinge arm 4 is transferably fitted in a long hole 8 in the forward and backward direction formed in the hinge bracket 2, between the shafts 5, 6. The shaft 7 which is the rotary center on opening/closing the hood 9 is constituted so as to transfer back and forth in the long hole. In this way, the forward movement of the shaft 7 is prevented by the input load to the hood 9 in collision of the vehicle at the front face thereof.  And thereby, 7XX:c rotary movement to the opening direction of the hood 9 is restricted and the hood 9 brings out a sufficient resistant force at the fixed position.

IPC: G03G15/08
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of a stator by ozone gas by forming the stator of an elastic material containing at least non-diene polymer. SOLUTION: In a toner transferring pump 5, a stator 25 is formed of an elastic material containing at least non-diene polymer. When toner particles are passed between a rotor 24 formed of a rigid body and the stator 25, a stator part pressurized by the rotor 24 is elastically deformed, and thereby, external force applied on the toner particle is minimized. The stator 25 is elastically deformed simultaneously with rotation of the rotor 24, and thereby, heat generated by friction between the two 24, 25 is suppressed to the utmost, the toner particle is prevented from deforming and breaking, and the toner is prevented from condensing. Since non-diene polymer has ozone resistance, generation of cracking caused by ozone generated at the time of operation of a charging device and a transfer charger is obstructed so as to prevent condensing and fixing of the toner from generating.
