Patent JP-S58190130-A (JP)
Title: Electronic switch unit particularly operated without contact
Inventor: ROBERUTO BUTSUKU
IPC: H03K17/945
Filed: 1983-03-28
Abstract: A contactless motion detector is energized from a source of current via a pair of supply leads and delivers an output signal by way of a further lead through an Exclusive-OR gate to a control electrode of a binary electronic switch in circuit with the source and a load to modify the flow of load current upon the approach of a metallic element, for example. The Exclusive-OR gate, having one input connected to that further lead, has another input connected to an ancillary lead which in turn is connected to the other supply lead through a decoupling diode. A selector switch enables completion of the load circuit directly via the latter supply lead, thereby causing inverted transmission of the output signal of the detector to the control electrode, or by way of the ancillary lead to prevent the inversion of that output signal, whereby the load current can be either increased or reduced upon the occurrence of the event to be detected.

Title: Wide-band and high-efficiency amplifier
Inventor: HONJIYOU KAZUHIKO
IPC: H03F1/02
Filed: 1982-03-29
Abstract: PURPOSE:To realize a high-efficiency amplification throughout a wide band, by supplying bias voltage and current through an inductor which has a sufficiently high impedance. CONSTITUTION:A signal inputted to a terminal 11 is amplified by a grounded- source amplifier. The AC load of an FET is a resistance RL and a DC stopping capacitor CB which are connected to a drain 12. Since the AC load is a resistance having no frequency characteristic, the operation of the amplifier is stable throughout a wide band. The DC bias to the drain 12 is performed through an inductor LB. The inductor LB has a sufficiently high impedance in the band where the amplifier is operated. Since extra power is not consumed because of the absence of the loss of DC, the efficiency of the amplifier is improved.

IPC: H01L21/336
Filed: 1984-03-16
Abstract: PURPOSE:To improve the withstanding voltage of an insulating film by forming the insulating film containing iron to a semiconductor substrate. CONSTITUTION:A silicon substrate 1 as a semiconductor substrate is dipped in an aqueous solution containing iron in concentration of 10ppb-10ppm and ammonia water and hydrogen peroxide water for approximately one min, and iron is adsorbed to the surface of the substrate 1. The substrate 1 is taken out of the inside of the solution, and a silicon oxide film 2 as an insulating film is formed on the surface of the substrate 1 through thermal oxidation. Iron uniformly distributes into the silicon oxide film 2 at that time, and concentration thereof extends over 1X10<16>-5X10<18> atoms/cm<3>. An Al-Si electrode 3 is shaped on the oxide film 2, and an ohmic contact surface 4 is formed on the back of the substrate 1, thus manufacturing an MOS diode.

Title: Electronic equipment with power source abnormality detecting circuit
Inventor: SHIMIZU OSAMI
IPC: G06F1/00
Filed: 1984-03-19
Abstract: PURPOSE:To easily investigate the cause of malfunctions and to take proper countermeasures, so as to improve the reliability of electronic equipment, by installing a detecting circuit which detects abnormality of the power source and a means which stores the abnormal condition and reproduces the abnormal condition at need to the equipment. CONSTITUTION:When abnormality occurs in an AC power source 1, positive and negative abnormal voltages are respectively detected by abnormal voltage detecting circuits 2 and 3. Absolute values of th detected voltages are compared with each other at a comparator 6 and higher one is selected and inputted to an AD converter 11. Another comparator 12 outputs an interrupt signal to a microprocessor (MPU) 13 when the abnormal voltages exceeds a prescribed value, and causes the MPU13 to read the AD converted pulse signal. Upon completing the reading operation, the MPU13 outputs a reset signal to a relay (K)16 through an output interface 15 and resets the circuits 2 and 3. The data of the abnormal voltages read by the MPU13 are displayed on a display device 17 through the display key of a key operating unit 19 and, at the same time, printed by a printer 18. These abnormal data can be reproduced at need.

Title: Complementary fet logic circuit
Inventor: KOMATSU TAKEO
IPC: H03K19/00
Filed: 1978-04-27
Abstract: PURPOSE:To obtain a C-IGFET logic circuit featuring a small amount of the power consumption by inserting P-channel type IGFET between the drains of P- and N-channel type IGFET circuits which are used in pairs and thus reducing logic amplitude. CONSTITUTION:When input IN features a low potential, P-channel IGFETP11 is turned on to charge load capacity C1 of output OUT. And voltage VOH occurring at OUT rises up only to the level decided by the value obtained by subtracting threshold voltage VTHP from power voltage VDD owing to the voltage drop of only VTHP of P-channel IGFETP12. When input IN is at a high potential, N-channel IGFETN11 is turned on to discharge the charge stored in load capacity C1. Thus, voltage VOL occurring at the output is lowered down to the GND level. Amplitude V of output OUT becomes as V = VOH - VOL = VDD - VTHP. As the current flowing to GND from the power source is proportional to amplitude V, the power consumption is reduced more than that in the case of the amplitude between power  source VDD and GND.

Abstract: PURPOSE:To protect etching electrode and effectively prevent temperature rise of samples to be etched by providing an flat insulating plate providing holes for inserting samples in the non-contact condition with electrode at the upper area isolated by only a short distance from said etching electrode. CONSTITUTION:A quartz plate 20 is supported by a supporting means 21 at the upper area isolated by only a short distance from an etching electrode 8. A sample 10 is directly placed on the electrode 8 through a hole 22 and when the specified number of samples 10 are all placed thereon, the surface of etching electrode 8 is perfectly covered with samples 10 and quartz plate 20 and thereby protected from impact of ion.

Abstract: PURPOSE:To improve the picture input/output processing function in response to the number of processor elements by providing a FIFO type frame memory to each processor element and receiving the output of the final stage of plural processor elements connected in series to output the received output as the picture data. CONSTITUTION:The picture data received from a picture input part 1 is sent into a frame memory 3a of a processor element 3 of the first stage via a synchronism control part 2 and then sent to a frame memory of the processor element of the next stage. Then memory 3a has an old FIFO type and therefore needs a fixed time before the picture data sent into each memory 3a is outputted. The picture data is fetched into a processor 3b in the fixed time via a data input/output part 3c. Then the picture data is sent back to its original position of the picture data flowing through the memory 3a via the part 3c after execution of a prescribed process. As a result, the picture input/output processing function is improved in response to the number of processor elements.

Abstract: PURPOSE:To improve the measurement accuracy of a propagation time of a pulse wave, and to execute the quantitative determination measurement of a degree of local artery hardening by using together a time measurement by a correlative processing with a measurement executed by a Doppler signal, based on the measurement executed by the Doppler signal. CONSTITUTION:Doppler signals 14, 15 are stored in waveform storage parts 16, 17, and each partial waveform 18 of a temporary storage signal 23 is subjected to Fourier transformation by a Fourier transform 19 and stored in a Fourier storage part 20 as a Doppler time series frequency spectrum. From a result of decision of a signal extracting part 21 for selecting a wide band signal part of a Fourier storage part 20, only a specific part of the temporary storage signal 23 is selected by a signal selecting part 22 and it becomes a reference signal 24. A correlation arithmetic part 26 calculates a mutual correlation coefficient 27 of a reference signal 24 and a temporary storage signal 25, and a moving time from an origin at the time when the maximum value in this waveform appears becomes a pulse wave propagation time between observation points 12 and 13. In this case, a signal converting part 50 corrects the variation direction or the variation width of a frequency of the Doppler signal of Doppler measuring parts 10, 11 and it is stored in waveform storage parts 16, 17.
