Abstract: PURPOSE: To restrain vibration absorption t the minimum and reduce dead center noise by providing a working delay type connecting means between a reaction plate and a damper plate and integrally rotating both of the plates when a clearance in the peripheral direction is eliminated because of relative rotation. CONSTITUTION: A bearing 13, an elastic means 9 and a vibration absorbing means 16 are interposed between a first weight 1 having face plates 3, 4 and a second mass 20 free to relatively move with this and having a damper plate 11 and a reaction plate 14, and damping and vibration absorption between the two masses 1, 20 is carried out. Additionally, a working delay type connecting means 30 to engage a projected body 31 on the side of the plate 11 to demarcate a peripheral direction clearance J against initial relative rotational displacement with a slot 32 of the reaction plate 14 is provided between the reaction plate 14 and the damper plate 11, and when the clearance J is eliminated, the both plates 14, 11 integrally rotate.  Consequently, it is possible to idealistically absorb dead center noise by restraining vibration absorption to the minimum at the time of engine low speed rotation.

Title: Adhesion inhibitor of combustion residue
Inventor: UCHIKAWA HIDEFUSA
IPC: F01N1/24
Filed: 1982-01-29
Abstract: PURPOSE:To obtain the adhesion inhibitor of combustion residue capable of removing tar or soot on the surface of a sound absorbing base material rapidly and perfectly, by combining a solid acid catalyst with an adhesion inhibitor consisting of graphite fluoride and a heat resistant binder. CONSTITUTION:The adhesion inhibitor of combustion residue used in coating the surface of the sound absorbing material of an exhaust muffler apparatus for an internal combustion engine is constituted by containing and dispersing graphite fluoride low in surface energy in a heat resistant binder along with a solid acid catalyst. When the surface of the aforementioned sound absorbing material is coated with this adhesion inhibitor, the polymerization of tar is suppressed to smoothly blow off almost all tar from said surface and the adhesion of tar or soot can be availably prevented.

Abstract: PURPOSE: To prevent the occurrence of cracks in the vicinity of the central hole of a high pressure turbine rotor by desulfurizing a molten low alloy steel having a specified composition for the rotor to ≤0.002% S value analyzed in a ladle.  
     CONSTITUTION: A low alloy steel for a high pressure rotor contg. 0.25W0.35% C, 0.15W0.35% Si, <1.00% Mn, 0.90W1.50% Cr, 1.00W1.50% Mo, 0.20W0.30% V, <0.75% Ni, <0.015% P and <0.018% S is refined in an electric furnace. This molten steel is desulfurized in a ladle refining furnace to ≤0.002% S value analyzed in the ladle. It is then cast in a vacuum, and the resulting ingot is worked into a high pressure turbine rotor by an ordinary forging method and heat treatment. Thus, the occurrence of cracks in the vicinity of the central hole of the rotor is prevented during use.

Title: Manufacture of electric double layer capacitor
Inventor: SAITO TAKAYUKI
IPC: H01G11/10
Filed: 1990-01-26
Abstract: PURPOSE:To provide a title condenser reduced in size and increased in capacitance by manufacturing active charcoal by carbonizing thermosetting resin at 500-700 deg.C. CONSTITUTION:When polarizable electrodes are formed of mixture of active charcoal 1 and electrolyte solution, and a current collector 2, and a capacitor is manufactured, the charcoal is manufactured by carbonizing thermosetting resin at 500-700 deg.C. When the resin is carbonized, a transition point for varying from resin to carbon precursor exists between 400 and 500 deg.C. Thus, a large difference exists at equivalent series resistances at between 400 and 500 deg.C. On the other hand, when the carbonizing temperature is raised to advance carbonization, weight is reduced and contraction occurs. Since the influence of the reduction in the weight is large up to the vicinity of 650 deg.C, the surface area of the carbide becomes maximum near at 650 deg.C. Since the influence of the contraction of the carbide at 650 deg.C or higher is large, pores are gradually vanished. Accordingly, its capacitance is apparently large, and a range of the carbonizing temperature having no problem at the value of the equivalent series resistance is 500 deg.C or higher and 700 deg.C or lower. Thus, a large capacitance is provided with small size.

Title: Semiconductor device
Inventor: YATANI YUTARO
IPC: G11C11/418
Filed: 1992-01-30
Abstract: PURPOSE:To prevent the transmission of data from delaying even when a power source noise ocurrs at a reading time in a static memory circuit connecting at least two or above bit line pairs to a common data bus line pair through a CMOS pass gate. CONSTITUTION:The bit line pair Bn, Bn and bit line select MOSFETs Pn, Nn indicate respectivly P type and N type. However, the threshold value VT of the P type MOSFET Pn is made larger than the VT of other P type MOSFETs in the static memory circuit. Since the VT of the bit line select MOSFET in the static memory circuit is made large and the bit line select P type MOSFET in a non-selection state is not turned on even when a power source noise ocurrs at a reading time, only the data of the bit line selected regularly is transmitted to a data bus and a delay caused by the quarrel of the data in the data bus is prevented.

Filed: 1984-02-01
Abstract: PURPOSE:To obtain a deflection characteristic the same as that when no external magnetic field exists by providing a detector detecting the external magnetic field, and controlling a deflection current in response to the detected output. CONSTITUTION:Magnetic field detectors 7, 8 detect the external magnetic field in X and Y directions around a cathode-ray tube and the detected output amplified by amplifiers 9, 10 controls respectively a horizontal deflection amplifier 3 and a vertical deflection amplifier 4. The deflection is corrected to a value subtracting the effect of the external magnetic field so as to obtain an object deflection after the said external magnetic field is superimposed on the magnetic field due to the said deflection current in advance in both X and Y directions. Thus, the effect of the external magnetic field is cancelled substantially and the deflection characteristic as designed is obtained.

Abstract: PURPOSE:To facilitate grinding of material hard to be ground by dispersing air bubbles of 10mm or less in diameter, and setting the volume to be 20-95%. CONSTITUTION:To a metal which was melted, grinding particles 1 having volume 2-40% of the metal 3 are added while the metal 3 is stirred. Next, a foaming agent is added thereto while they are stirred to form inside thereof air bubbles 2 having diameter of 10mm or less and volume 20-95% of the whole, resulting in obtaining of a required foaming metal wheel. As a result, it is possible to enhance strength of the foaming metal wheel produced as well as retaining force for grinding particles, and also, to effectively supply a grinding liquid to the surface to be ground, and further to escape powders ground in a good manner. It is thus possible to grind and polish a material hard to be ground such as ceramics or cemented carbide, with this wheel. During operation, the grinding particles 1 are protruded from the surface of metal 3 through the application of voltage between the wheel and the material to be ground, and therefore, it is possible to automatically make good arrangement of particles of this wheel.
