Patent JP-S57177555-A (JP)
Title: Semiconductor device
Inventor: ISHII YOSHIAKI
IPC: H01L27/112
Filed: 1981-04-27
Abstract: PURPOSE:To control the wave length of an ultraviolet visible absorption edge not exceeding 300nm without fail as well as to provide the plasma Si3N4 film with sufficient strength and chemical resistance by a method wherein the plasma Si3N4 film setting up the atomic ratio of Si and N to be 0.65-0.825 is utilized as a mask. CONSTITUTION:There is a specific functional relation between the wavelength lambdaa of an ultraviolet visible edge and the Si/N ratio, i.e., in case the Si/N ratio exceeds 0.825, lambdaa>300nm, while in case the ratio does not exceeds 0.65, the processing will be hardly performed due to the excessive etching speed, while in case the ratio is approximate 0.75-0.8, both the wavelength and the corrosion resistance will be acceptable. When the component ratio Si H4/NH3 of the reacting gas is selected to provide the plama Si3N4 film of the specified Si/N, say as the final protective film of EPROM, the strength and the chemical resistance will be acceptable and the wavelength lambdaa may be controlled not to exceed 300nm without fail in case the ultraviolet rays are erased by means of radiating said rays to the gate of the memory unit.

IPC: G01F1/696
Filed: 1994-03-31
Abstract: PURPOSE: To calibrate response time without a sensor receiving an air flow by laser-trimming a pair of bias resistances of a balanced bridge control circuit, making the initial bridge offset voltage equal to a desired value. CONSTITUTION: A sensor head has heating resistance RH and low temperature resistance RC extended into a sensor air passage and exposed to air flow. An electronic circuit 20, which is formed of a balanced bridge circuit, has resistances RH, RC within its branched passage. The value of initial bridge offset voltage Vbr is measured as the difference V2 -V1 of voltages V2 , V1 measured in connecting points 26, 24 in the circuit 20. The offset voltage VOS is calculated by the expression I. The value of a constant C1 for controlling the response time of the sensor (the smaller the value, the shorter the response time) is calculated by use of the expressions II, III. When the measured Vbr is larger (less than) than a required Vbr , the resistance R<7> (R<6> ) is laser-trimmed to increase the resistance value, and the value of Vbr is reduced (increased) and made equal to a desired value.

Title: High-speed packet exchange device using special dividing type switch
Inventor: AMADA EIICHI
IPC: H04L12/931
Filed: 1988-03-18
Abstract: PURPOSE:To enable the packet of fixed length to be exchanged at a high speed by analyzing the header of the packet from each input port, deciding the packet which can be outputted, controlling the connection of a switch and outputting the packet which can be outputted all at once. CONSTITUTION:The delay of the packets arriving at output ports 112-1-112-32 is fluctuated according to the number of the input port from which the packet is outputted and the connection path of the spacial dividing type optical switch 106. Therefore, the bit phase synchronization is needed to be executed by an output side. Then, a clock used for outputting the packets from output control circuits 102-1-102-32 is wave-length-multiplied, sent to the output port by the identical path and bit phase synchronization is executed after temporarily storing the packet inputted from the input port in an input buffer. That means, by an arbiter 108, the packet which can be outputted is decided and the connection path of the switch 106 is set. Then, the packets are outputted all at once from the circuit 102-1-102-32.

IPC: H02G15/113
Filed: 1995-02-28
Abstract: PURPOSE: To make it easy to set a cable connection in a cable connection housing, enhance safety and hermeticity, and significantly improve assembling workability. CONSTITUTION: A sleeve 1 is vertically divided into two in the axial direction to form butting mating faces. The opposed mating faces are coupled together by a securing means, and the divided halves of the sleeve are thereby integrated into one to form a closure. At least one insertion hole 20 is formed in an end face plate 3 to be attached to the sleeve 1. Slits 22 that connect to the insertion holes 20 are formed in the periphery of the end face plate so that the periphery can be opened at the slits 22. This makes it possible to simply fasten the sleeve using a fastener with the mating faces of the halves of the sleeve butted together. This remarkably facilitates the work of leading cables out of, covering and housing, the cable connection, and ensures the sleeve with reliable hermeticity.

Title: Automatic reset circuit
Inventor: SUZUKI OSAMU
IPC: H03K17/22
Filed: 1979-05-23
Abstract: PURPOSE: To inhibit a reset signal from being generated even with a power voltage lowering by providing a latch circuit which stays ON until the power voltage decreases down to a fixed potential.  
     CONSTITUTION: When voltage line l 1  rises in potential V cc  from zero above V cc = 4VBE (VBE; forward voltage drop of diode), currents flow through thyristor-connected transistors T 1  and T 2  to set a latch state. When latch circuit (b) turns ON temporarily, its ON state is maintained until power voltage V cc  is lowered approximately down to zero. On the other hand, when V cc =2VBE, transistors T 3  and T 4  turn ON and when VCC=4VBE, both turn OFF. During this period, a reset pulse is output to output VO. Once a single reset pulse is output, the latch circuit stays ON even if power potential VCC lowers, so that any reset signal will not be generated.

Abstract: PROBLEM TO BE SOLVED: To restrict partial discharge concentration being remarkable in DC-type discharge by making one surface of a discharge electrode pair an AC-type discharge electrode coated with an insulating film and the other electrode a DC-type discharge electrode where the front surface of electrode metal is exposed to gas space. SOLUTION: A discharge electrode anode 7, a cathode 8 and a partition 6 are aligned in a stripe shape in parallel and the surface of the cathode 8 is coated with an insulating layer 9. That is, one of the discharge electrode pair is the AC-type discharge electrode whose surface is coated with the insulating layer and the other electrode is a DC-type discharge electrode where the surface of electrode metal is exposed to gas space. Thus, at least one of the surfaces of the discharge electrode of a display device, that is, the anode 7 or the cathode 8 is made to be AC-type electrode structure coated with the insulating layer and an impression pulse for exciting discharge is arranged so that DC reference potential is prevented from fluctuating.  When one of the discharge electrodes is made to be the AC-type electrode, the capacitance of the insulating layer on the surface is serially inserted to a discharge path so as to play a roll for loading or current restricting.
