Abstract: PURPOSE:To adhere a metal fine particle in a uniform adhesion amount and a uniform particle size regardless of the shape of an object to be adhered, by contacting a hydrogen sorbing metal having H2 sorbed therewith by the electrolysis of water with an aqueous solution containing Rh, Pd or Pt. CONSTITUTION:Water is usually electrolized in an alkali (e.g., NaOH) aqueous solution according to a usual method by using a hydrogen occluding metal as a cathode. In this case, the temp. of an electrolyte is usually 0-100 deg.C and current density is 0.001-5A/cm<2>. In the next step, the hydrogen occluding metal (the metal to be adhered) after the completion of electrolysis is contacted with an aqueous solution containing Rh, Pd or Pt. The aqueous solution containing Rh, Pd or Pt is the one containing a Rh compound (e.g., rhodium sulfate), a Pd compound (e.g., palladium sulface) or a Pt compound (e.g., platinic chloride). The hydrogen sorbing metal to which a metal fine particle is adhered by the aforementioned contact treatment is suitably used as a hydrogen permeable membrane and water electrolysis electrode as well as can be used as the electrode of an electric conductivity meter and the electrode for water electrolysis using a caustic alkali aqueous solution.

Abstract: PURPOSE:To provide a zinc shop coat primer for use in high-speed welding, which has excellent weldability, workability, rustproofness, etc., by mixing a soln. of colloidal silica in an org. solvent with polyvinyl butyral and then mixing the mixture with an extender pigment, a suspending agent and zinc powder. CONSTITUTION:A soln. of colloidal silica in an org. solvent is mixed with polyvinyl butyral in a weight ratio of pref. 100:0-35 on a solid basis. The mixture is mixed with a conventional extender pigment, a conventional suspending agent and zinc powder in such an amount that the amount of zinc powder accounts for 50-70% of the resulting dry coating film, thus obtaining the desired zinc shop coat primer for use in high-speed welding. The org. solvent is evaporated from the coating film of the org. solvent type colloidal silica, whereby the dry film is converted into a completely inorg. matter which contains no hydrogen source. Since polyvinyl butyral has a low heat decomposition point and is heat-decomposed during welding and converted into a material which contains less hydrogen sources, the resulting zinc shop coat primer has excellent weldability.

Abstract: PURPOSE:To improve the reliability by pushing a hollow seal member in which a mandrel material having elasticity in a tip part of a piston rod and a cylindrical body are fitted and placed in the inside into an oil passage of a work, sealing it, and executing a pressure leakage test. CONSTITUTION:At the time of executing a pressure leakage test of an oil passage 5, a work 6 is positioned on a jig base 2, and by operating a clamp cylinder 9, a clamp plate 10 is allowed to descend and the work 6 is fixed. Subsequently, by operating a seal cylinder 12, a piston rod 14 is allowed to ascend, and a seal member 17 is pushed into the passage 5. In this state, an expanded diameter part of the member 17 corresponding to a cylindrical body 16 is pressed against the inner wall surface of the passage 5, and also, placed in the upper part of an oil escape groove 21, therefore, compressed air does not reach the groove 21 and does not leak to the open air. Thereafter, compressed air is brought to force feed into the passage 5 and injected, and a prescribed pressure leak test is executed. In this regard, since a mandrel material 15 is allowed to have elasticity by using a spring steel material, it does not occur that its material is bent and damaged in accordance with a working position of the passage 5.

Title: Controller for ac-dc converter
Inventor: SUZUKI HIROKAZU
IPC: H02J5/00
Filed: 1996-01-22
Abstract: PROBLEM TO BE SOLVED: To prevent operation at a value, where DC voltage differs from a rated value, for a prolonged time by correcting the DC-voltage set value of a converter in response to the difference of the set value and detecting value of effective power while correcting the set value of effective power by the response later than the correction. SOLUTION: The effective-power detecting value Pa of a converter is augmented (or reduced) with the decrease (or increase) of the effective power of another converter constituting a DC transmission system. Consequently, an output from a coefficient multiplier 18 reaches a negative value (or a positive value), and DC voltage Ed is controlled by a DC-voltage controller 20 so as to be made lower than an initial DC-voltage set value Edref because a DC- voltage set value Edrefx is lowered (or increased) when the output is input to an adder 19.  On the other hand, the output from the coefficient multiplier 18 is added to an initial effective-power set value Pref through a primary delay circuit 17 and an effective-power set value Prefx is increased (or decreased) gradually to reach an equal value to the effective-power detecting value Pa, and the DC-voltage set value Edrefx is brought to the intitial voltage set value Edref, a rated value.

Title: Detector for ply feed
Inventor: YAGASAKI TOSHIAKI
IPC: G03G21/00
Filed: 1981-02-27
Abstract: PURPOSE:To enable to detect a feed of paper being stuck together having various thicknesses by detecting the spacing between sheets of paper at a place between the first feed part provided with a sheet separating means and the  second feed part feeding the sheets at a higher speed, in a duplicator capable of  feeding paper continuously. CONSTITUTION:When the front end of the sheet is detected by a light-emitting diode PD and a photo-transistor PT, an H-signal is generated, which is changed to an L-signal at the rear end of the sheet, and the signals are inverted by an inverter Q1 to produce a trigger signal upon the detection of the rear end. By the trigger signal, a mono-stable multivibrator Q2 is set and maintained at an H level for a predetermined period of time. Next, when the second sheet is fed in a condition of stacked state feed, the sheets are separated from each other, while the third sheet reaches the sensor 50 earlier than in normal cases. Since the signal Q2 is at the H level at this time, an H signal is fed from an AND gate Q3 into a CPU, thereby detecting the paper feed being stuck together and feed rollers are controlled accordingly.

Title: Substrate bias circuit
Inventor: MATSUO RYOSUKE
IPC: G11C11/408
Filed: 1991-01-29
Abstract: PURPOSE:To enable a pump efficiency of a charge pump circuit in a substrate bias circuit which gives a bias potential to the substrate of a semiconductor integrated circuit. CONSTITUTION:A transistor T5 conducts when a control signal A rises from a potential Vdd to Vss, transmits a potential -j.Vdd of a node N1 according to a capacitor C1 to a node N2 and then performs one-stage booting, and becomes non-conductive when a control signal B rises from the potential Vdd to Vss, thus playing a role of a two-stage booting for obtaining an approximate -2Vdd by adding -m.Vdd to a potential of the node N2. Conduction of a transistor T2 is controlled by the potential of the node N2. Therefore, a node control circuit 33 plays a role of reducing a gate potential of the transistor T5 to (-J.Vdd-Vthp) or less for allowing the transistor T5 to conduct completely at a specified timing. Even if a power-supply voltage of an integrated circuit is low, a pump efficiency of a charge pump circuit is high and can be operated fully even at a low power-supply voltage, thus enabling a node of an output edge to be set to a specified level rapidly also when a circuit is started after power is turned on.

Filed: 1995-02-16
Abstract: PURPOSE: To improve the pressure detecting sensitivity by using a pressure sensitive conductive elastic body having a conductive film formed by applying a conductive material to the pressing surface side opposed to the contact side with a fixed contact. CONSTITUTION: Top end parts 30a, 30b, 30c, 30 of a pressure sensitive conductive elastic body 30 consisting of a pressure sensitive conductive rubber having a conductive film 33 formed by applying a conductive material to the pressing surface side opposed to the contact side with fixed contacts 19-22 are arranged on the upper parts of four pairs of independent contacts 19-20. When a control lever 32 is pushed by an A-directional force, a B-directional force corresponding to the pushed position acts on four protruding parts of a pressing plate 31. Since a down force is particularly added to the body 30 as B1 , B2 , the resistance value between the upper and lower parts of the top end parts 30a, 30b, 30c, 30c of the body 30 is measured, whereby 'direction' and 'magnitude of force' that in which direction and which force is added can be known.  Compared with a conventional structure using an upper film, a more sensitive pressure detection can be performed.
