Title: X-ray exposing method
Inventor: OSADA TOSHIHIKO
IPC: G03F1/22
Filed: 1988-11-25
Abstract: PURPOSE:To improve a through put by suppressing the rise in temperature of a mask and by applying plenty of X-rays by a method wherein the temperature of the X-ray irradiation region of the mask is detected, and when the detected temperature deviates from a holding temperature, the flow rate and the temperature of gas are controlled, and the temperature rise of the mask on an X-ray irradiation region is prevented. CONSTITUTION:The temperature of the light-irradiation part of a membrane detected by an infraeye thermometer is inputted to the main control part 30, and when the temperature is deviated from the ambient temperature, a signal is sent to a nozzle controller 28 and/or a heater controller 29 from the main controller, the degree of opening of a valve 26 and the conducting current of a heater 27 are controlled by the above-mentioned controllers, and the deviation of temperature is eliminated. As the gas fed to a gas feeding tube 25 is cooled down, a membrane 22a is intensely cooled by increasing the flow-rate of gas by opening the flow-rate control valve 26, and a reverse result can be obtained by throttling the flow-rate control valve 26. Also, if the current allowed to flow to the heater 27 is increased, the temperature of gas is raised, and the degree of cooling is lowered. Through the above-mentioned procedures, the rise and fall of temperature on the light irradiation part of the membrane 22a are suppressed, and the membrane can be maintained at a fixed temperature.

Title: Logic circuit
Inventor: YODA RYUICHI
IPC: H03K19/088
Filed: 1988-11-28
Abstract: PURPOSE:To increase the voltage of a high level output by providing a 4th transistor (TR) of opposite conduction type whose emitter is connected to a 1st output signal means and whose collector is connected to a 2nd power supply means and a 5th TR of same conduction type. CONSTITUTION:When a high level input signal is supplied to an input IN, NPN TRs Q1, Q5 are turned on and an NPN TR Q2 is turned off, a PNP TR Q3 and an NPN TR Q4 are turned off. Then a low level is outputted from an output OUT. With an input signal of a low level supplied to the input terminal IN, the TRs Q1, Q5 are turned off and TRs Q2, Q3, Q4 are turned on. Thus, a high level is outputted from the output OUT. Since a collector-emitter voltage VCE of the PNP TR Q3 is smaller than a base-emitter voltage VBE of the NPN TR, the high level output voltage VOH is increased.

Abstract: PURPOSE:To avoid the generation of entrapment of oxide into the outer peripheral surface of a cylindrical body in a solidified process and to prevent the deterioration of quality of a centrifugal cast tube by making the inner part of a mold into the temporary closed space before pouring molten metal and introducing inert gas or reducing gas into this closed space. CONSTITUTION:Partitioning walls 6, 7 arranged to the temporary closed space in a cylindrical mold 1 are constituted with a meltable aluminum thin bode. By this method, even in the case of not removing or not opening/closing the partitioning wall, this partitioning wall is melted with heat of the poured molten metal by the heat of the poured molten metal, and by melting this partitioning walls, the pouring of the molten metal is executed without difficulty from the opened part. In such a way, in this result of executing the pouring of molten metal into the mold 1 in the inert atmosphere or the reducing atmosphere, the molten metal is not flowed into the mold 1 while entrapping the oxygen in the atmosphere, and the generation of the entrapment of the oxide in the outer peripheral surface of the cylindrical body is restrained and the deterioration of the quality in the centrifugal cast tube can be prevented.

To the number of person detecting part 54, the difference waveform outputted from the comparison part 52 and the low frequency component outputted from the extracting part 53 are inputted. In the detecting part 54, a comparison operation is executed to form the waveform obtained by subtracting the low frequency component from the difference waveform and a maximum point on this waveform is counted, thereby, the correct number of the persons can be detected.

Title: Laser trimming device
Inventor: KUNIHIRA MAMORU
IPC: H01C17/22
Filed: 1990-11-05
Abstract: PURPOSE:To allow a laser trimming device to immediately stop trimming when a fault occurs in the edge sensor of a probe card by providing a probe position detecting section which reads the position of a probe holder. CONSTITUTION:When the contactor 13 and conductor 14 of an edge sensor 2 become electrically disconnected to each other, a signal is sent from an edge sensor detecting section 4 to a probe controlling section 7, and the probe stops lowering. Then a probe position detecting section 8 measures the position of a probe holder 5 and the positional data of the holder 5 are sent to a trimming controlling section 9. When the position of the holder 5 is lower than a prescribed position, it is discriminated that the holder 5 is at a normal position and trimming is continued. However, when the positional data of the holder 5 measured by the section 8 are higher than the prescribed position, it is discriminated that a fault occurs in the edge sensor 2 or the holder 5 is not lowered due to a certain fault occurring in this laser trimming device and the trimming is stopped.

Title: Paper sheet conveyor
Inventor: NISHIJIMA YASUO
IPC: B07C1/00
Filed: 1991-11-15
Abstract: PURPOSE:To accurately detect the timing of passage and the length of each paper sheet and the interval to the next one in conveying transparent paper sheets. CONSTITUTION:A pair of opposite conveyor belts 20 convey paper sheets 10 such as postal matter in a direction C of carriage. An ultrasonic sound emitter 30 and an ultrasonic sound receiver 40 constantly transmit and receive ultrasonic waves to and from each other and this transmission line is blocked by the paper sheets 10. When the paper sheets 10 are made of transparent members, transmission of the ultrasonic waves is blocked by the paper sheets 10, which is different from the case with a photoelectric switch. A converting portion 50 detects the timing at which transmission is blocked and converts this detection information into an electric signal and sends it to a control portion 60. The control portion 60 produces outputs required to control the conveying of the paper sheets, such as the timing of passage and the length of each paper sheet 10 and the interval to the next one.

IPC: G02B6/42
Filed: 1986-12-16
Abstract: PURPOSE:To surely identify the existence of optical signal transmission in a single core by inclining the inside faces of a slit and using the inclined faces as reflecting faces.

Title: Electromagnetic flow meter
Inventor: KOSHIMIZU ATSUSHI
IPC: G01F1/60
Filed: 1991-10-21
Abstract: PURPOSE:To enable a timing signal which is in synchronization with commercial power source noise to be created. CONSTITUTION:Noises which are superposed on a fluid is detected by a noise- detection part 8 and only a commercial power source frequency component is taken out of the noises by a band-pass filter 9. Then, a pulse signal at a timing of each half period of the commercial power source frequency is output by a pulse-generation part 10 based on the noise signal and a sampling timing and excitation current timing are generated from a timing-signal generation part 12 by a signal which is in synchronization with the commercial power supply noise, thus enabling excitation coils 2a and 2b to be excited at the timing and enabling a flow rate signal to be sampled. A timing signal which is in synchronization with the commercial power source frequency is obtained highly accurately by eliminating spike noises which are superposed on the detection signal from an electrode and noises having frequencies in a band except the commercial power source frequency.
