Filed: 1980-04-30
Abstract: PURPOSE:To stabilize the final output, by giving an A/D conversion to the output of a variable amplifying circuit to set the amplification factor of the variable amplifier according to the output of the amplifying circuit and at the same time giving a fine adjustment to the amplification factor of the variable amplifier. CONSTITUTION:Both AGC circuits 31 and 32 are set at a prescribed amplifier at the time during which no received signal arrives at the circuits 31 and 32. When the received signal arrives, a rectifying circuit 33 detects the amplified signal and supplies it to an A/D converting circuit 34. An arithmetic circuit 35 performs an operation of the ratio between the voltage ED that means the waveheight value of the A/D conversion input and the voltage VS that is desired as the output of the circuit 32. The result of this operation is set again as the amplification factor of the circuit 32. This amplification factor receives a fine adjustment by the fluctuation of the A/D conversion input. As a result, the final output delivered from the circuit 32 is stabilized.

Abstract: PURPOSE:To minimize the reflection of a pressure wave in a pressure chamber and to continuously stably inject ink by holding the width of an ink supply port in a specific dimensional relation to the width of the chamber. CONSTITUTION:The pressure chamber 1 of an ink jet recording head is composed of a cylindrical glass tube 2.

Abstract: PURPOSE:To improve the resolution of positions, by bundling scintillators of many layers, coupling the layers optically, and detecting the incident positions of radiation into the scintillators and the depth positions of the light emitting points in the scintillators. CONSTITUTION:The title detector is composed of scintillators 11 comprising, e.g., three layers, a reflecting material 13 and an optical position detector 15.
