Title: Developer supply device
Inventor: UMEDA ARATA
IPC: G03B27/30
Filed: 1980-12-09
Abstract: PURPOSE:To make developing gas concentration constant in a developing tank, and not to waste developing gas, by controlling so that voltage across a capacitor becomes reference voltage in accordance with a difference output of a differential amplifier, and constituting so that a developer control device is operated in accordance with said difference output. CONSTITUTION:When a copying machine is turned on by an electric power source, reference voltage V1 from a reference voltage generating circuit 28, and voltage V across a capacitor 24 are inputted to a differential amplifier 29, this output is inputted to a current controlling circuit 30, and a current I is supplied to the capacitor 24. As a result, the voltage V across the capacitor 24 is always held at the reference voltage V1, but when photosensitive paper passes through in a developing tank in said state, in accordance with which a switch 27 is closed, the capacitor 24 is discharged through a resistor 26, and the voltage V drops. Therefore, an output of the differential amplifier 29 cbecomes high, and a developer control device 33 is operated by a pulse generated from a V/F converter 31 in accordance with said output.

Title: Wafer polishing fixing plate
Inventor: HASHIMOTO HIROMASA
IPC: B24B41/06
Filed: 1992-06-30
Abstract: PURPOSE:To provide a wafer polishing fixing plate making it possible to obtain a wafer of high flatness without micro unevenness on the polished face. CONSTITUTION:A soft resin layer 3 is formed on the wafer suction face of a wafer polishing fixing plate 1, and a hard resin layer 4 is formed thereon. When a wafer W with micro unevenness existing on the back face is sucked by the fixing plate 1, the micro unevenness on the back face side of the wafer W is sucked by the elastic deformation of the soft resin layer 3, so that the polished face of the wafer W is not influenced by the micro unevenness on the back face side. Also, since the wafer suction face of the fixing plate 1 is formed of the hard resin layer 4 of high rigidity to secure high flatness, the wafer W is sucked in the almost undistorted state. Accordingly, even when the wafer W is removed from the fixed plate 1 after the polishing of the wafer W, its flatness is kept high without the generation of deformation to the wafer W.

Title: Fet mixer
Inventor: SUGIURA SADAHIKO
IPC: H03D9/06
Filed: 1983-09-20
Abstract: PURPOSE:To eliminate the need for the adjustment for optimizing a circuit to a frequency component by utilizing that almost no current flows to a gate of an FET so as to a bias through a resistor. CONSTITUTION:A capacitor 12 is selected to a large static capacitance value so as to be almost short-circuited even to an intermediate frequency, then the capacitor 12 is almost short-circuited and a transmission line stub 15 and a transmission line 16 are almost short-circuited. Since a gate current flowing to and FET7 is very minute, no effect is given to the supply of bias even if a resistor 14 is selected as nearly 10kOMEGA. Thus, the resistor 14 can be regarded as a nearly infinite resistance, and the impedance viewed from a gate terminal G toward the external line is nearly zero. Since the condition of an input matching circuit to an intermediate frequency component when an FET mixer offers the highest performance in general is that the gate terminal G is short-circuited, the input matching circuit is optimized two frequencies, that is, the input signal frequency and the intermediate frequency.

An operated signal from the amplifier A3 is compared to the reference voltage by the amplifier A4. When the operated signal exceeds the reference voltage, a light-emitting diode (warning device) 34 is operated to display the changes in resistance of a transparent body heating circuit. Thus, the disconnection for the transparent body 10 can be detected with high accuracy.
