Title: Manufacturing of foamed molded article
Inventor: KASHIMURA MUTSUHIKO
IPC: C08J9/16
Filed: 1980-05-08
Abstract: PURPOSE:To manufacture foamed molded articles by bead molding without over- filling, by reacting a compound having two or more active hydroxy groups with the acid anhydride group of a styrene-maleic copolymerized resin and also impregnating a foaming agent thereto. CONSTITUTION:With a styrene-maleic acid copolymerized resin is reacted a hydroxy compound having 2-4 active hydroxy groups of 2.5-150mol% with respet to the maleic anhydride molecule of the resin, and a volatile foaming agent is impregnated in the above described resin thereby to form foaming particles. Then, the foaming particles are introduced in preliminary foaming particles, and are formed in a mold in an amount equal to or 10% excess of the capacity of a cavity of the mold thereby to obtain a formed molded article of a low specific gravity and an excellent thermal stability. As copolymerized resin particles, those containing 5- 15wt% of maleic acid and having a mean polymerization degree of 900-2,000 are preferable.

Title: Method for mountin fitting to coated stainless steel wire rope
Inventor: HAMADA KOUICHI
IPC: B21F15/00
Filed: 1980-05-09
Abstract: PURPOSE: To make fit of fittings easy, to intensify their pulling force and to eliminate the failure of the coating and the fittings per se by using the fittings of the shape corresponding to the dimensional shape owing to compressive tightening of wire ropes and the material of the plastic deformation characteristics conforming to purposes.  
     CONSTITUTION: A nickel type free-cutting stainless steel having undergone softening and annealing and skin-pass working is cut to a precribed shape, after which it is subjected to nonoxidation solution heat treatment, thereby making fittings 1. The minimum diameter O. dr of a wire rope which is compressed to a range in which the wire rope coating material is not damaged is determined by the equation I (η; the diameter of the total strands of the wire rope, δ; the diameter of each strand thereof, (t); the thickness of the coating, (x): an allowance for shrinkage, k 1 , k 2 ; the coefft. of correction). The required volume V 0  of the fittings (spherical body) is the equation II (Cb; the thickness of a rough ball prior t worling, Rb; the diameter thereof, (a); a coefft., V; the volume to be removed by cutting). If the wire rope 2 is gripped by the fittings 1 while a coating layer 3 is held put and the wire rope is compressed from above the fittings, the fittings 1 conform to the surface shape of the rope 2, thereby deforming and biting the same.

Title: Constant temperature water tank of simple structure
Inventor: ABE YUKINDO
IPC: G05D23/20
Filed: 1982-04-15
Abstract: PURPOSE:To make it possible to control the temperature of constant temperature water with a high degree of accuracy in the same manner as in the case of a manual control operation by a method wherein a set temperature determined by a digital switch is operated to coincide with the characteristic of a temperature sensing element and the current feeding time for a heater is controlled on the base of the difference between the set temperature and the temperature detected by the temperature sensing element. CONSTITUTION:The outputs of thermosensors 15 and 16 attached to the constant temperature water tank 1 are applied on differential amplifiers 19 and 23 through linearizers 17 and 18, respectively. Further, a temperature to be set by the digital switch 21 of a temperature setting device is read out in a programmable processor 20 and is operated to coincide with the output of the linearizer 17 of the thermosensor 15 and after being passed through a D/A converter 22, it is outputted to the differential amplifiers 19 and 23. The output of the differential amplifier 19 is then transmitted to the processor 20 through a threshold value detector 24 where it is compared to the set value and when the output is lower than the set value, the feeding of electric current to the heater 13 is controlled. On the other hand, the output of the differential amplifier 23 is recorded in a recorder 36 which in turn controls the gain of the differential amplifier through the processor 20 so that the output is recorded within a predetermined range.

Title: Fuel cell system
Inventor: NONOBE YASUHIRO
IPC: H01M8/04
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To prevent the drop of a battery output voltage and an abnormal battery reaction at a system starting time so as to normally supply electric power to a load at the system starting time. SOLUTION: In a fuel cell system 10, a secondary battery 14 drives a motor 16 at a system starting time. This time, a fuel cell 12 supplies electric power to auxiliary machines 18 for which a predetermined low current is sufficient so as to conduct warming up. A temperature sensor 22 measures the inside temperature of the fuel cell 12 so as to transmit the measurement result to a control portion 24. The control portion 24 judges the warming up state of the fuel cell 12 based on the measurement result, and drives a change-over switch 20 so as to connect the fuel cell 12 and the motor 16 mutually when the warming up terminates.

Title: Start fuel injection timing control device for internal combustion engine
Inventor: MUNAKATA HIROKI
IPC: F02D41/06
Filed: 1995-02-24
Abstract: PURPOSE: To prevent fuel blow by at starting and reduce starting time by calculating injection timing based on overlapping start time of an intake/exhaust valve, reached time of injected fuel to a combustion chamber and fuel injection time. CONSTITUTION: ECU 5 operates injection time of fuel by a fuel injection valve 6 and detects at least one of engine rotational frequency by a CRK sensor 13, engine temperature by a water temperature sensor 10 and intake air temperature of an engine by an intake temperature sensor 9 and reaching time of the injected fuel to a combustion chamber using various table data in response to this detected output. The ECU 5 further operates overlap timing when an intake valve and an exhaust valve of the engine 1 are simultaneously opened. Fuel injection timing is calculated based on the overlap start time, the fuel reaching time and the fuel injection time preferably such that the fuel injection is finished before the overlap start time. Whereby, blow by of the fuel is prevented to reduce emission.

Title: Hose coupling for faucet
Inventor: TAKAGI TOSHIO
IPC: F16K17/30
Filed: 1980-05-10
Abstract: PURPOSE: To prevent vibration due to the change in secondary pressure at a hose coupling in which a water port is automatically shut off by abnormal pressure in a hose, by gradually closing the water port with a valve.  
     CONSTITUTION: When a neck 1 is fitted on a faucet and a hose 9 is connected to a body 10, the body is pulled up to an ascent position by a spring 17 and a valve 22 is moved into a cylindrical part 6 of middle diameter so that a water port 8a is opened. When secondary pressuree in the hose 9 has increased due to the folding or the like of the hose 9, the pressure acts to a bellows 18 through the water port 8a and compresses the spring 17 to move down the body 10 so that the valve 22 shuts off the water port 8a to stop water outflow. When the valve 22 shuts off the water port 8a, the water passage constriction is gradually effected because of a slope 27 at the water port 8a. For that reason, the valve 22 does not vibrate.

Abstract: PURPOSE:To improve the efficiency through the reduction of mechanical frictional loss by making a distance of up to a rotation supporting part from the spherical pair supporting center of a lever member imparting its revolving motion to rollers larger than another distance of up to the supporting center of these rollers. CONSTITUTION:When a rotor part 18 of a compressor driving motor is rotated, the center of spherical parts 19a and 19d of a lever member 19 performs a circular motion, a revolving motion is imparted to two rollers 21 and 22 supported in a spherical pairing manner by these spherical parts 19a and 19d, the increase or decrease of capacity is repeated in each of cylinders 1 and 2. At this time, supposing load relations to be produced by pressure in compressed gas acting on each circumference of these rollers 21 and 22 are as follows; the center of these spherical parts 19a and 19b is a load point, the center of a spherical part 19c is a fulcrum and the center of a spherical bush 16 is a force point respectively, a distance between the fulcrum and the force point is large enough as compared with that between the fulcrum and the load point, so that a size of the load acting on the force point is sharply reduced by the principle of the lever. Therefore, either of sliding speed or sliding load is reducible at each sliding part.
