Title: Self-color-forming pressure-sensitive recording sheet
Inventor: IIDA TOSHIZO
IPC: B41M5/124
Filed: 1993-06-02
Abstract: PURPOSE:To improve an unnecessary color-forming stain while keeping a necessary color-forming performance in a self-color-forming pressure-sensitive recording sheet. CONSTITUTION:A recording layer of a self-color-forming pressure-sensitive recording sheet is covered with a protective sheet. Both the sheets integrally adhere to each other through an intermediate layer mainly composed of a pigment and an adhesive. As the protective sheet, wood free paper, under paper for no-carbon required paper, or the like can be used. A release strength between the self-color-forming pressure-sensitive recording sheet and the protective sheet can be adjusted by the coating amount of the intermediate layer, the kind of the adhesive, the kind of the pigment, the ratio of the adhesive to the pigment, and the like. This recording sheet is remarkably improved in unnecessary color-forming stain occurring in a self-color-forming pressure-sensitive recording sheet and exhibits a superior color-farming performance.

Title: Precision location device
Inventor: OKUZONO HIROMI
IPC: B23Q5/44
Filed: 1985-06-18
Abstract: PURPOSE:To enhance the feeding accuracy for a slide table in the sliding direction by pinching spheres with a nut retaining part and a table plate in such a way that they are capable of rolling. CONSTITUTION:A joint 4, bearings 6, 7 and a feed screw 5 are rotated by driving a motor 1. Thereby a nut 10, a nut retaining part 11 and a slide table 17 are fed.

Title: Magnetic-field detector
Inventor: FUKUSHIMA YUUJI
IPC: G01R33/02
Filed: 1979-10-15
Abstract: PURPOSE: To enable employment of a two-core cord and make the device substantially free from noises by a method wherein a feed wire is short-circuit by an open-and-close element, such as a thyristor, which operates corresponding to a magnetic-field detection pulse and thereby the connection between the detection circuit and an outside power source is controlled.  
     CONSTITUTION: When a rotary magnetic-field and the like is detected by a bridge circuit formed of magnetic resistance effect elements 10 and 10' and bias resistances 11 and 11', a pulse is outputted from the operational amplifier 2 of a waveformshaping circuit. Then, a thyristor 12 in parallel to the amplifier 2 is placed in the state of continuity and the receiving terminals 13 and 13' of a magnetic-field detector 8 are short-circuited, whereby the pulse s received by the receiving circuit 4 of a receiving device 9. Then, a switch 14 is turned off through the intermediary of the circuit 4 and accordingly, the connection between the outside power source 5 and the detector 8 is broken. By this constitution, when the thyristor 12 is turned off, the switch 14 is turned on. By this shared constitution of the power line and the signal line, the detector and the receiving device can be connected with each other by the two-core cord without using a three-core cord. In addition, since the detection outut signal is a loop signal which short-circuit the feed wire, the current which flows turns large, whereby the device is made substantially free from noises.

Title: Production of oxidation product and generation of power using solid electrolyte membrane integrated with gas turbine
Inventor: DRNEVICH RAYMOND FRANCIS
IPC: F02C3/22
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To integrate an ion transport membrane reactor with a power generating system and produce both a power and an oxidation product by bringing an oxygen- containing gas stream into contact with a solid electrolyte oxygen ion transporting membrane in a reactor, reacting a reactant with oxygen, producing the oxidation product and adding the resultant oxygen-reduced gas to a gas turbine combustor. SOLUTION: A compressed and heated oxygen-containing gas stream (air) is brought into contact with one or more solid electrolyte oxygen ion transporting membranes to transport a part of the oxygen across the membranes from a retention zone to a permeation zone in a method for producing an oxidation product such as a synthesis gas in connection with a gas turbine system for generating a power. Thereby, a permeated stream and an oxygen-reduced retention stream are produced. A reactant such as a hydrocarbon is fed to the permeation zone and reacted with the oxygen to afford the oxidation product. The oxygen-reduced retention stream is added to a turbine combustor and heated by combusting reaction thereof with a fuel and converted into the oxygen-reduced gas stream, which is then recovered from the turbine combustor and expanded in a turbine expander for generating the power.

IPC: F16H61/08
Filed: 1984-06-27
Abstract: PURPOSE:To prevent the generation of switching shock by adjusting the time ranging from the switching operation of a shift lever to the discharge of the working oil of a hydraulic actuator by a control-time adjusting means. CONSTITUTION:Each output supplied from an engine revolution speed detecting means and a lever operation detecting means is input into a control-time adjusting means, and the time ranging from the switching operation time for a shift lever to the start of discharge of the working oil for an actuator is adjusted in the relation predetermined on the basis of the engine revolution speed by the control-time adjusting means. Therefore, even in the state where the engine revolution speed is high such as in first idling or idling, the generation of switching shock due to the operation of the shift lever from neutral range to advance range can be solved.

Title: Measuring force converter
Inventor: FUJISAWA KATSUHIDE
IPC: G01B5/06
Filed: 1984-06-29
Abstract: PURPOSE:To enable easy and quick exchange of the force pressing a sample with a measuring terminal, by arranging a cylinder, a step, a transmission rod having an outward flange, a sleeve, a diaphragm for keeping airtightness and an air feed/exhaust to a clearance. CONSTITUTION:Sleeve tubes 21 and 22 are internally inserted into a cylinder 19 fixed in the vertical way, channels 24 and 25 are made on the top and bottom of the tube 21 respectively while a channel 35 is on the tube 22 so as to communicate with feed/ exhaust ports 26, 27 and 34 provided on the side of the cylinder 19. A transmission rod 37 is inserted slidably through the tubes 21 and 22 in the vertical way to keep airtightness and regulate movement with an O ring, a diaphragm, a step and the like. A comparator end for measuring the lift level thereof is made to abut elastically on the upper end of the transmission rod. Compressed air is fed or exhausted separately through the feed/exhaust ports. With such an arrangement, to reduce the measuring capacity, air is passed through the feed/exhaust port 26 to lift the sleeve tube 21 and a downward push is given by the force of the transmission rod itself alone with the other feed/exhaust ports 27 and 34 set the same in the condition. To enlarge the measuring capacity, the feeding of air to the feed/exhaust port 24 is stopped to apply forces of the transmission rod and the sleeve. To lift the transmission rod, air is simply fed to the feed/exhaust ports 27 and 34.

IPC: H03K3/356
Filed: 1988-05-31
Abstract: PURPOSE:To attain high speed operation and low power consumption by decreasing the difference from the response time till the level of each output terminal is decided in applying preset or clearing. CONSTITUTION:NAND gates 4, 8 and OR gates 7, 14 constitute a master flip- flop circuit 19 and NOR gates 2, 10 and AND gates 9, 13 constitute a slave flip-flop circuit 20. In applying preset, the output level of an output Q depends on three stages comprising an inverter 1 and the NOR gates 2, 21 and the output level at an output, the inverse of Q depends on two stages comprising the inverter 1 and the NOR gate 22, and the difference from number of stages between both the outputs is only one stage. This is applied similarly to the case in applying clearing as with the case of application of preset. Since the response time and its difference till the level of each output terminal is decided are reduced in this way, high speed operation and low power consumption are attained.
