Title: Bit correction equipment
Inventor: IRIKITA NOBUYUKI
IPC: H01L21/268
Filed: 1985-02-25
Abstract: PURPOSE:To prevent the generation of bit correction failure, by installing the link detecting system, the laser system and the controlling unit provided with the operating unit, comparing unit and controllers. CONSTITUTION:When the surface of the semiconductor device 1 is irradiated by the light source 26 of the detection optical system 22 and the link 2 is scanned, the detected signal SX1 and SY2 are obtained by the CCD's 32 and 33. By processing these signals in the processing unit 41, calculating them in the operating unit 42, memorizing the width W1, length L1 and the position of the center X1, Y1 in the memory part 43 and operating the controller 45, the center of the link 2 is set at the center of the laser optical system 21. By operating the controller 48, the laser beam of the laser source 23 is converged through the objective lense to melt and cut the link 2. The detection optical system 22 detects again the link 2 and obtains the signals SX2 and SY2. The signal processing unit 41 and the operating unit 42 calculate the width W2, the length L2 and the position of center X2, Y2 of the hole 3 formed by melting. These values are compared with the memorized data W1, L1, X1 and Y1 in the comparing unit 44, and the result of melting is confirmed. Thus, the bit correction failure can be prevented and the reliability of the bit correction can be increased.

Title: Deficit voltage detection circuit
Inventor: NOMURA YOSHISHI
IPC: G01R19/165
Filed: 1985-02-26
Abstract: PURPOSE:To enable deficit voltage in the 50Hz and 60Hz districts to be detected by addition of simple circuits by arranging so that a device adapted to detect the voltage level by comparison with a reference voltage of a DC voltage obtained by rectifying the AC voltage is annexed by a phase difference detector for producing an AC voltage having a phase delay of 90 deg. from the AC voltage and its rectification circuit. CONSTITUTION:The capacitances of capacitors 11, 14 are set so as to be equal in impedance to resistors 12, 13 at 55Hz. The potential ex at a junction presents a voltage waveform delayed 90 deg. with respect to the terminal voltage eb relative to a mid point zero V. The resistance 13 and the capacitor 14 operate to delay the junction point potential ey by 90 deg. with respect to the terminal voltage ea, with the phase of the potential ey being of a waveform of opposite polarity, or 180 deg. out of phase with the potential ex. The voltages at these two points are rectified by a rectifier 15 and added to a voltage obtained after rectification by a rectifier 2 of the secondary voltage of the alternating current supplied to a control transformer 1. Thus the two phase full-wave rectified waveform is obtained and the potential ed smoothed by a resistance 3 and a capacitor 4 is free of ripples so that deficit voltage of 50Hz and 60Hz is detected accurately.

Abstract: PURPOSE: To improve workability by forming a floor together with sleepers, and leading a pipeline having one end connected to a kitchen and sanitary space facility, under the sleepers at the time of providing the facility on the floor. CONSTITUTION: A pipeline 16 with one end connected to a wash stand 14 or the like is led under a plurality of sleepers 5 forming a floor 1, thereby eliminating the need of forming a notch on the sleepers 5 when the pipeline 16 is laid thereon. In addition, the pipeline 16 is supported on the sleepers 5 at a plurality of positions, thereby ensuring the pipeline 16 to be fixed to the floor 1. Furthermore, the sleepers 5 are made of metal, and the strength of the floor 1 becomes high, even when the height of the sleepers 5 is small. As a result, a piping size under the floor 1 can be enlarged. Also, the pipeline 16 is factory mounted on the sleepers 5 and, therefore, a piping work at the construction site can be lessened.  In this case, a piping work becomes easy without any need for a worker to stay under the floor 1 by inverting the floor 1 in upper and lower positions and restoring the floor 1 to an original state after piping. According to this construction, piping work efficiency can be improved.

Title: Ice-making device
Inventor: INOUE YOSHINORI
IPC: F25C1/14
Filed: 1988-02-18
Abstract: PURPOSE:To prevent freezing lock of a rotary drum, by providing a means which intermittently suspends running of a compressor during ice-making operation, reduces a rotation load by melting of ice formed on the rotary drum, and restarts running of the compressor after reduction of the load. CONSTITUTION:During ice-making operation, running of a compressor 8 is intermittently suspended by a starting stopping means, and during suspension, the feed of a refrigerant to an outer pipe 3 of a vaporizer 1 is stopped. Thus, ice formed on the inner pipe is molten to reduce the load of the rotary drum of the vaporizer 1. After reduction of the load, running of the compressor 8 is restarted by means of the starting stopping means to start ice-making. This cycle controls and runs the compressor 8, and prevents the occurrence of lock due to freezing between the inner pipe 2 and the rotary drum.

IPC: H03M1/14
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To obtain an A/D converter which can hold power consumption to minimum and an increase in area and also convert analog signals at the same time. SOLUTION: Analong input signals S1 and S2 are sampled, held by S/H circuits 201 and 301, and then have their high-order (m) bits roughly converted by A/D converting means 310 and 312 and held by registers 320 and 321, and are reproduced into analog signals by D/A conversion parts 311 and 313. Analog subtracters 203 and 303 subtracts the analog signals of the D/A conversion parts 311 and 313 from the signals held by the S/H circuits 201 and 301. Then the subtraction results are converted by the A/D converting means 312 and 310 to perform the minute conversion of the lower-order (m) bits, and the results are held by the registers 320 and 321. A digital adder 330 adds the higher-order and lower-order bits of the analog signals of two inputs after digital conversion and also generates the A/D conversion result of the analog input signals S1 and S2 at the same time.
