Abstract: PURPOSE:To prevent the decrease in copying accuracy of a copying device for welding provided with a sensor utilizing high frequency current owing to a change in temp. by providing a variable capacity circuit and a correcting circuit for the purpose of correcting the malfunction of the sensor owing to the temp. change. CONSTITUTION:In a copying detector which supplies the high frequency current from an oscillating circuit 2 to a detecting coil 5 of a sensor 1, and detects the change in the current owing to a change in an inductance when the sensor 1 attaches and detaches to and from an object to be detected by means of a detecting circuit 8, micro DC current is supplied to the coil 5 to discover the abnormality such as overheating and disconnection of the detecting coil. In order to prevent the decrease in the copying detection accuracy owing to a rise in the temp. of the sensor 1, the change in the capacitance with a change in temp. is offset with a variable capacity circuit 11 provided with a threshold setting circuit 15 and a comparator 13. The conductance characteristic value of the detecting circuit by the change in temp. is corrected linearly with a correcting circuit 12 whereby the influence of temp. upon the detection accuracy of the copying detector is prevented.

Title: Short-circuit detection circuit of power source transformer
Inventor: HOTTA CHIHARU
IPC: H02M7/12
Filed: 1990-06-05
Abstract: PURPOSE:To improve circuit protection and safety by operating a protection network when each of secondary side terminal of a power source transformer is short-circuited. CONSTITUTION:Resistance values of divided resistances 10, 11 are chosen so as to make the emitter voltage of a transistor 9 lower than the base voltage when a power source circuit is in a normal condition, and to make the emitter voltage higher than the base voltage when a power source transformer 1 is short-circuited between 1-pin and 2-pin. When the power source circuit is in a normal condition, since the base voltage of the transistor 9 is higher than the emitter voltage, the transistor 9 is in an OFF state. When the power source transformer 1 is short-circuited between 1-pin and 2-pin, the base voltage of the transistor 9 is lower than the emitter voltage, and the transistor 9 is thus in an ON state, and voltage is generated in a collector thereby, and an overvoltage protection network 12 is activated, so as to turn the primary side of the power source circuit OFF. The circuit protection and safety can thus be improved.

Abstract: PURPOSE:To enable uniform coating of a photoresist including no foreign material in resin by directing downwardly the surface to be coated of a semiconductor substrate, bringing the substrate into contact with the resin liquid surface while rotating the substrate, isolating both and rotating the substrate. CONSTITUTION:The semiconductor substrate 25 is so set at a wafer chuck 24 connected to a motor 27 that the surface to be coated becomes downside, is lowered downwardly while rotating the motor 27, and is brought into contact with the liquid surface 23 of the photoresist 22 filled in the tank 21 more than once.

When affirmative judgement is obtained, the polling is performed on the device 251 corresponding to the address 1. Next, when a response from the device 251 is received at a transmission/reception part 235, the flag corresponding to the address 1 is changed to 0 after the affirmative judgement. The processor 231 adds 1 on the address value (i) and repeats the similar processing.
