Title: High resolution thermal recording head
Inventor: SAITOU MASAYUKI
IPC: B41J2/345
Filed: 1982-05-19
Abstract: PURPOSE:To obtain the titled head, wherein the surrounding of a heating resistor body is enclosed by a member having good heat conductivity, mutual thermal effect between neighboring heating resistor bodies can be decreased, cutting of dots is improved, and high resolution recording can be performed. CONSTITUTION:A high heat conducting heat radiator 6 is arranged between neighboring heating resistor bodies 2 on an insulating substrate 1 and connected to a common electrode 4. The heat radiator 6 is formed so that the length is longer than the size of the heating resistor body 2 between both electrodes 3 and 4. For example, when a current is flowed through the heating resistor bodies 2b and 2c, extra yielded heat is radiated through the electrodes 3b and 4 and 3c and 4. The heat also escapes to the common electrode 4 through the heat radiators 6a and 6b. As a result, the effect of the heat of the heating resistor bodies 2b and 2c to the heating resistor body 2a is largely reduced.

Title: Voltage comparator
Inventor: HOSHINO YOSHIKUNI
IPC: G01R19/165
Filed: 1980-06-25
Abstract: PURPOSE:To obtain a small-hysteresis voltage comparator which is suitably IC- implemented, by generating an offset voltage by varying the operation current ratio of an input differential couple of transistors (TR) of a differential input type voltage comparator according to an output state. CONSTITUTION:A differential input type voltage comparator is composed of pnp TRs Q1 and Q2, npn TRs Q3 and Q4, a constant-current source I0, etc. When a reference voltage VREF is higher than an input voltage VIN, an output VOUT is at a high level and a switch SW stays off. Then, when the VOUT goes to a low level and the switch SW is closed, a current flows from a hysteresis power source IH to the TRQ3. Therefore, then the VOUT goes to the high level again, collector currents of TRs Q1 and Q2 are unbalanced to generate an offset voltage with hysteresis width which corresponds to the voltage VH of the power source IH, thereby adjusting the hysteresis width according to the offset power source without any resistance, etc. As a result, a small hysteresis voltage comparator which is suitably IC-implemented is obtained.

Title: Abnormal discharge preventing electrode for arc vapor deposition device and its manufacture
Inventor: SAKAMOTO KAZUYUKI
IPC: C23C14/24
Filed: 1993-03-23
Abstract: PURPOSE:To prevent the abnormal discharge in the surface of electrode undesirable in discharge by covering a part of the metal to be evaporated with an oxide film in the vapor deposition device using an arc discharge. CONSTITUTION:The cathode electrode used as the metal to be evaporated is heated in a furnace such as electric furnace under atmosphere, and naturally cooled to form electrically insulating oxide film on the surface of the electrode. About 0.1mum oxide film thickness is sufficient for effectively preventing the abnormal discharge. When the oxide film having sufficient insulation properties can not be obtained by the heating method, the surface of the electrode is coated with chromium oxide, aluminum oxide or silicon oxide, etc., by using an ion plating or sputtering method, etc. Since the whole surface of the electrode is coated with these oxide in these methods, the oxide film is formed by preliminarily sealing the surface to be discharged. Alternatively, after forming the oxide film on the whole surface of the electrode, the oxide on the necessary surface is ground with an emery paper, etc.
