Title: Garbage disposer
Inventor: MORISHITA TAKUYA
IPC: B02C18/00
Filed: 1993-01-28
Abstract: PURPOSE:To decompose garbage for disposal in a short time and safely check the inside of a disposal tank by providing a garbage grinding means, a disposal tank, a treating medium, a mixing means and a cutout switch for stopping the grinding means and the mixing means when a freely opening and closing door is opened. CONSTITUTION:In garbage disposing operation, a helical body 12 is rotated to send garbage through a garbage entrance opening 10 to the forward end of a transfer cylinder 9 to grind up the garbage by fixed teeth 11 and rotating teeth 14 and the ground garbage is discharged therefrom into a disposal tank 15. The ground garbage in the disposal tank 15 is mixed with treating medium 33 by rotation of a stirring blade 16 and is eliminated by decomposition into water and carbon dioxide by the bacillus and coccus naturally occurring in the treating medium 33. In case the garbage incapable of being decomposed by the treating medium 33 should be placed into the disposal tank 15 by mistake or the transfer cylinder 9 of a grinding machine should be clogged up, when the door of the disposal tank 15 is opened, a cutout switch is activated to prevent the operation of a grinding machine driving motor 13 and of a stirring blade driving motor 19, even if a switch is turned on, thereby making a safe operation possible.

Title: Vertical gap automatic location method of cutting blade at rotary slitting shear device
Inventor: TANABE NOBUO
IPC: B23D15/08
Filed: 1978-02-08
Abstract: PURPOSE: To automatically control the gap by approximating to a sine wave the movement relation between a running gear and a shearing blade.  
     CONSTITUTION: A carried steel plate 1 is sheared between upper and lower shear blades 2, 3 of a rotary slitting shear device. The fixed movement G of the upper shear blade 2, which is vertically adjusted according to the thickness of the steel plate 1, has a circular relation with the fixed movement θ on the running gear side, due to the arrangement of a transmission running gear; it can be approximated as G=Acosθ + C. The compensation Δθ for rmoved layer θ due to the blade abrasion ΔG is shown as θ + Δθ = cos -1 {(G + ΔG - C)/A}, which can be obtained by a reversed trigonometrical function generator 36. The fixed movement on the running gear side is automatically controlled through a feed-back circuit.

Title: Multicylinder internal combustion engine
Inventor: FUJIEDA YASUO
IPC: F02B75/10
Filed: 1979-02-06
Abstract: PURPOSE: To recirculate exhaust gas in reliable manner and to thereby minimize the amount of NO x  contained in the exhaust gas, by carrying out recirculation of exhaust gas by way of exhaust- pressure controlling method, and preventing that control for the recirculation of exhaust gas is affected by supply of the secondary air into the exhaust system.  
     CONSTITUTION: When throttle valve 7 is fully closed, valve element 26 is located in a position closing an exhaust-gas recirculating passage. When the throttle valve 7 is opened, however, valve element 26 is opened so that exhaust gas is recirculated to the intake system. When recirculation of exhaust gas is started, negative pressure in controlling valve 22 is lowered so that recirculation of exhaust gas is stopped. Recirculation of exhaust gas is carried out through the repetition of the above procedures, and the amount of exhaust gas recirculated is increased with increasing of exhaust pressure that is caused by the opening of throttle valve 7. When the throttle valve 7 is fully opened, negative pressure at a sensing port becomes equal to the atmospheric pressure, so that controlling valve 22 is opened and recirculation of exhaust gas is stopped. On the other hand, suction of the secondary air is caused by a combined effect of exhaust-gas pulsation in exhaust pipe 12 and suction in the other pipe 13 caused by the flow of exhaust gas. Here, by a proper positional  relationship of inlet port 18 and outlet port 21, it is prevented that exhaust pressure is disturbed by the drawing of the secondary air into the exhaust pipe.

Abstract: PURPOSE:To prevent the gas leakage, by making an outer diameter of a washer of self holding type solenoid for a solenoid valve for use with a gas instrument or the like slightly greater than an inner diameter of a washer inserting portion of a valve rubber, and thereby eliminating a gap between a valve rubber receiver and the valve rubber. CONSTITUTION:An outer diameter phid of a water 9 is greater than an inner diameter phiD of a washer inserting portion 8a of a valve rubber 8 by about 0.3-1mm. Accordingly, the washer 9 is forcibly inserted into the washer inserting portion 8a of the valve 8 in such a manner as to expand the latter. As a result, an outer peripheral portion of the valve rubber 8 is bent in the direction of an arrow, and is urged against a valve rubber receiver 7 to closely contact same regardless of whether or not a dimension A of a recess 7a of the valve rubber receiver 7 is equal to a dimension B of a projection 8b of the valve rubber 8 to be engaged with the recess 7a.

Abstract: PURPOSE:To reduce the reflection on the surface of a plastic lens, by coating a thin film of Al2O3 on the surface of the plastic lens and then a thin film of MgF2 on the Al2O3 film. CONSTITUTION:The Al2O3 thin film II having a high adhesion to the plastic B with a larger refractive index than the same plastic is coated by vapor deposition on the surface of an optical parts such as a plastic lens or the like. Furthermore the thin film I of MgF2 having a smaller refractive index is evaporated on the film II to obtain an evaporated film C. Thus the spectral reflection properties of the plastic lens can be varied to the wavelength of incident rays by changing the thickness of the film II and film I each.

Title: Optical information recording/reproducing device
Inventor: SHIKICHI SATOSHI
IPC: G11B7/24
Filed: 1989-01-25
Abstract: PURPOSE:To discriminate the upper side from the rear side of an optical information recording medium having an equal reflection factor between its both sides by using a means which detects the depth of a light reflecting surface and discriminating the upper and rear sides of the recording medium based on the detected depth of the reflecting surface. CONSTITUTION:When an optical card 1 is set normally, a distance sensor 2 is positioned so that the distance is set at l0 between the sensor 2 and a card substrate 1b serving as a reflecting surface. In this case, the output current of the sensor 2 is equal to I0. When the card 1 is set upside down, the distance l1 between the sensor 2 and the substrate 1b is less than the distance l0. In this case, the output current I1 of the sensor 2 is less than the current I0. Thus it is possible to decide whether the card 1 is set normally or not based on a fact that both currents I0 and I1 are different from each other. As a result, the upper and rear sides are discriminated from each other for an optical recording medium having an equal reflection factor between its both sides.

Title: Device for protecting thyristor converter
Inventor: INO HIDETOSHI
IPC: H02H7/12
Filed: 1979-02-13
Abstract: PURPOSE: To eliminate the damage of a thyristor by a device for protecting a thyristor converter by temporarily interrupting the stop of a gate pulse signal by a switching element when a damage occurs during a gate pulse.   
     CONSTITUTION: When a power supply malfunction occurs during the period while a gate control signal is generating to thus generate a power supply malfunction signal, a power supply malfunction signal to an OR gate 13 is generated after the period while the gate control signal is generating is ended. After a gate current incorporates a sufficient pulse duration, a current will therefore flow through the switching element 14 by a switching signal. Accordingly, the damage of a thyristor due to insufficient pulse duration of the gate is prevented.
