Title: Mask and its production
Inventor: HAMAGUCHI SHINICHI
IPC: G03F1/00
Filed: 1988-03-28
Abstract: PURPOSE:To improve the reliability of the mask by forming the parts changed in properties which lower transmittance in prescribed patterns to the glass plate itself and constituting the parts changed in properties in such a manner that said parts from the exfoliation free patterns. CONSTITUTION:A resist film 15 is first formed atop the glass plate 11. This film 15 is then subjected to patterning. Dry etching using chlorine plasma is executed under prescribed conditions to impart physical and chemical damages to the exposed parts of the surface of the glass plate 11, by which the parts 13 changed in properties are formed in the prescribed patterns on the surface of the glass plate 11. Finally, the resist film 15 on the surface is removed and the mask 10 is completed. Since the patterns are the parts which are changed in properties and are formed to the glass plate itself, the possibility of exfoliation of the glass plate itself is eliminated at all.

Abstract: PURPOSE: To improve compactation, stability of combustion and so on by composing a floatless variable Venturi carburettor using a fuel pressure regulator which consists of a diaphragm and others instead of a float chamber.  
     CONSTITUTION: When a key switch 10 is switched on, an electromagnetic valve 12 is put into a condition of continuity and a valve 12-4 leaves a seat 12-5 to open.

Filed: 1979-06-12
Abstract: PURPOSE:To realize a high-speed comparison of the minute voltage by forming the circuit with the differential amplifier, the FF plus the load resistance connecting the former two units. CONSTITUTION:First, a low level is secured for terminal 107 of FF block B1, and the terminal 107 is connected to the signal sources of terminals 101 and 102 of differential amplifier block A1. As a result, only block A1 is activated, and thus the difference of the signals is amplified to cause the output at terminals 103 and 104 each. Then the voltage is applied to terminal 107 to give the conduction to MOSFET121, and as a result MOSFET19 and 120 are activated each in the form of FF. And the FET of which the gate is connected to the higher side of the voltage conducts first, and accordingly the voltage of the output terminal connected to the FET lowers suddently. While the voltage of the other output terminal keeps a high potential. Here resistances 108 and 109 function to reduce the effect of the FF working to the action of the differential amplifier, and thus must have the resistance value same as or more than those of resistances 113 and 114.
