Title: Spherical lens array and its manufacture
Inventor: IKEGAMI YOSHIZUMI
IPC: G02B27/18
Filed: 1980-08-14
Abstract: PURPOSE:To obtain a high-prescision lens array and to prevent the generation of picture spots by closely cementing a lens array, used for the image sensor of a copying machine, etc.m ina cemented optical material having different refractivity with parallel planes cutting spherical lenses partially. CONSTITUTION:For a spherical lens array used for an image sensor, etc., a required number of bar-like spherical lens systems each consisting of spherical bodies of an optical material 2 in the optical axis are prepared in an optical material having different refractivity and their upper and lower parts are polished so that the spherical bodies are partially cut with planes parallel to the optical axis. Then, they are cemented putting the cut surfaces of the spherical bodies in close contact. Thus, the spherical lens array has a large diameter and is adjusted with high precision. In addition, since each lens contact part has no gap, the generation of picture spots due to deficiency in the quantity of light is prevented.

A winding groove 5 is made to another substrate 2, and this substrate is divided into two parts to obtain minor substrate 91 and 92. Then the substrate 111 and 91 are press-fixed with heat to form an I core 14. In the same way, a C core 15 is produced with use of the substrate 112 and 92. Then the gap butted face of the cres 14 and 15 receives a mirror surface finishing, and a nonmagnetic material film of SiO2, etc. is formed by the high frequency sputtering process or other methods. The butted face and the nonmagnetic material film are adhered together with the low melting point glass 16 to obtain a block 17.

IPC: G01R31/28
Filed: 1993-05-14
Abstract: PURPOSE:To eliminate the reduction in detecting ratio in inspection by fixing a short-circuited wiring to an optional logic value in the inspection for short- circuit failure of wiring. CONSTITUTION:The output of an inverter 105 is inputted to the gates of a P-type MOSFET 102 and a N-type MOSFET 103, and the output of a NOR 106 is inputted to the gate of a N-type MOSFET 104. The drains of the FETs 102, 103, 104 are connected to an output terminal 101, and the driving performances are set to 11, I2, I1-I2 (I1>I2), respectively. The output of the inverter 105 and a control signal 2 are inputted to the NOR 106. Thus, since a logic value 1 which is outputted only when the control signal 2 is the logic value 1 is driven with sufficiently large driving performance, compared with a logic value 0, the potential in a short-circuited position, when the logic values 0 and 1 are mutually short-circuited, can be necessarily fixed to the logic value 1.

Title: Power supply circuit
Inventor: FUNAMOTO TARO
IPC: G05F1/10
Filed: 1990-04-27
Abstract: PURPOSE:To raise the AC gain of an output voltage to shorten the time required for the change from the turning-on state to the turning-off state of the output by applying positive feedback from the power supply output to the base of a transistor TR through a capacitor. CONSTITUTION:When a switch 1 is depressed for the purpose of requesting voice recognition, the base current of a TR 4 flows through a resistance 2 to turn on the TR 4. Then, the base current of a TR 7 flows and the TR 7 is turned on, and the power supply output is turned on. In this case, potentials in both ends of a capacitor 3 are approximately equal to each other. When the voice recognition request is released and the switch 1 is released, the potential at a terminal A is gradually reduced because a current flows from the capacitor 3 to the base of the TR 4. When it approaches a voltage VBE, the base current of the TR 4 is reduced and the output voltage falls. Thus, TRs 4 and 7 quickly go to the cut-off state, and the output is turned off in a short time.
