Title: Resist coating device
Inventor: OGURA TAKETOSHI
IPC: H01L21/027
Filed: 1989-05-08
Abstract: PURPOSE:To easily remove the resist adhered to the surface of a chamber by a method wherein a film, which is easily dissolved by a solution, is formed on the inner wall of the chamber to be used for prevention of scattering of a resist. CONSTITUTION:In a resist coating device provided with a spindle on which the object to be coated such as a wafer and the like, a film 6 which dissolves easily in a solvent is formed in a chamber 2 to be used for prevention of scattering of a resist. For example, a high molecular film 6, which will be dissolved by an organic solvent, is coated on the inner wall of the chamber 2. As a result, the scattered resist is adhered to the high molecular film 6 when a resist coating operation is conducted, and when the chamber 2 is dipped into the above- mentioned organic solvent after the above-mentioned operation has been finished, the high molecular film 6 is dissolved. As a result, the resist is separated from the inner wall of the chamber 2, and the resist is exfoliated as one film. Then, when a high molecular film is coated on the inner wall of the chamber 2 which is dried up by the evaporation of the organic solvent, the preparation for the next resist coating operation is completed.

IPC: G03G21/00
Filed: 1992-05-07
Abstract: PURPOSE:To protect equipment for forming pictures from overload and abnormal ity of power supply, by stopping power supply when overload/or abnormality of the power supply is sensed. CONSTITUTION:After starting a software timer in a system chip 1, an A-D data of the feedback value at an input terminal PN12 is compared with a comparator data stored in a latch 121, i.e., the desired control valve of a feedback control. Then, when both the data do not coincide with each other, the comparison of the data is repeated. When the time preset by the timer elapses, it is determined that such an abnormality as short circuit of load or failure of power supply is generated in the system of low-voltage power supply. The, a main PWM 110 and sub-PWMs 111-113 are stopped, and by lighting and LED generation of abnormality is indicated. Thereby, equipment for forming pictures can be protected from overload and abnormality of power supply.

Abstract: PURPOSE:To optionally control a spread of a trapezoidal transmission output signal by outputting a peak level of a control voltage of an optional trapezoidal shape from a data latch circuit of a trapezoidal wave generator and allowing a power amplifier to generate an output signal with a trapezoidal envelope. CONSTITUTION:A data latch circuit 13 of a trapezoidal wave generator 3 extracts a peak level of a 1st optional trapezoidal wave control voltage Vc1 of a required kind and predetermined in advance in the order at sampling and outputs the level while giving a prescribed time width.

Title: Permanent magnet and its manufacturing and permanent magnet material
Inventor: SASAKI MITSUAKI
IPC: H01F41/02
Filed: 1994-04-28
Abstract: PURPOSE:To enhance an orientation and a formation by an easy method wherein interface active agent is added into water slurry of material powder to obtain a permanent magnet material composed of oxide permanent magnet particles for use. CONSTITUTION:Anion system interface active agent, or anion system interface active agent and nonion system interface active agent is (are) added into water slurry of material powder composed of oxide permanent magnet particles to be thereafter dried. Thus, it is possible to obtain a permanent magnet material composed of oxide permanent magnet material particles that the anion system interface active agent, or anion system interface active agent and nonion system interface active agent is (are) attracted onto the surface. As the surface of these particles is extremely low-frictional, contact friction of particles with respect to each other when molded becomes extremely small to considerably enhance orientation. Thereafter, a permanent magnet material is dry-molded in a magnetic field to obtain a compact, and next the compact is sintered to make a permanent magnet.

Title: Magneto-optical recording medium
Inventor: NIIHARA TOSHIO
IPC: G11B11/10
Filed: 1987-05-13
Abstract: PURPOSE:To improve the characteristics of a laminated magnetic layer and to increase the angle of Kerr rotation thereof by providing mixed films formed by mixing elements which easily form oxide dielectrics with SiO. CONSTITUTION:The elements, such as Si, Ti, Ta, Nb, Al, and Mg, which are liable to form the oxide dielectrics are added into the SiO film. Namely, the elements such as Si, Ti, Ta, Al, and Mg added into the SiO film capture the excess oxygen and free oxygen existing in the SiO film and prevent the reaction of said oxygen with the magnetic films. The impairment of the characteristics of the magnetic films are, therefore, obviated. The refractive index of the SiO film is decreased by the presence of the excess oxygen, free oxygen, etc., but these elements have the refractive indices larger than the refractive index of the SiO film and, therefore, the decrease in the refractive index, i.e., the decrease in the angle of Kerr rotation is prevented.

     CONSTITUTION: A clearance groove 6 is provided on each step of key-way 5 of a wheel 2 being symmetric with respect to the key-way by 180° around the axis. The key-way 5 and clearance groove 6 of each step are communicated with each other through a clearance groove 7 for cutting work of key-way, while the clearance groove 6 of the former step is connected to the key-way 5 of the next step. When the damp steam shown by arrows enters the key-way 5, it turns its course through the clearance groove 7 for cutting work of key-way and flows into the clearance groove 6 positioned symmetrically by 180° around the axis along the inner surface of wheel 2. Furthermore, the steam enters the key-way 5 of wheel 2 of the second step from the wheel 2 of the first step. Thereby, the damp steam is allowed to  escape in the lower stream rapidly without stagnation.
