Title: Driving machine utilizing magnetic force, gravity, and inertia force
Inventor: ASANO KOJI
IPC: H02K53/00
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To freely take out energy wherever and wherever, without being influenced by change in the weather and the nature by using natural energy such as a permanent magnet. SOLUTION: An electromagnet 1 is fixed to an upper part, and a movable permanent magnet 2 is arranged on a lower part. The lower surface of the electromagnet 1 is set to zero of a condition in which an electric pole is cut, and the upper surface of the permanent magnet 2 is disposed on a N-pole. As a result, the permanent magnet 2 at the attraction limit is moved upward. When the movement is completed, the electric pole of the electromagnet 1 is put in to become the N-pole. Repelling is generated, and the permanent magnet 2 is moved downward. Namely, power supply is switched, and thereby, vertical motion is repeated. The vertical motion is converted into circular motion by a crank, and a power generator is rotated to generate power.

Title: Synchronous data latch circuit
Inventor: UCHIDA MAKIO
IPC: H03K3/037
Filed: 1988-04-22
Abstract: PURPOSE:To prevent oscillation of a synchronous flip-flop by connecting plural gates, which have operation areas different from one another and are different in driving capability, in parallel as inverter gates of a latch loop used in the flip-flop. CONSTITUTION:In the flip-flop, the data input is transmitted to a latch circuit consisting of inverters 2a, 2b, and 2c and a feedback clocked inverter 3 through a transfer gate 4 controlled by a clock input CLK and a signal obtained by inverting this input CLK by an inverter 1. Gray zones a', b', and c' for the input voltage of various inverters 2a-2c overlap one another. When the input voltage exists in an area l7 which is not included in gray zones of inverters at all, the output level of one or more inverters out of inverters 2a-2c is certainly stabilized for any input voltage level, and therefore, oscillation of the flip-flop is prevented.

Filed: 1986-04-28
Abstract: PURPOSE:To obtain optical parts having excellent resistance to staining and scratching and workability by forming an org. material-contg. curable material on the surface of antireflective films and specifying the surface reflectivity and static contact angle with water of the optical parts to prescribed values.

Title: Engine control apparatus
Inventor: ISHIKAWA HIDEAKI
IPC: F02D41/00
Filed: 1984-05-18
Abstract: PURPOSE:To prevent engine-stall due to over-rich air-fuel mixture at the time of starting an engine, by calculating the fuel pulse width at the time of starting the engine on the basis of an arbitrary engine speed and a start signal, and injecting fuel by the starting pulse width until the engine speed is raised to said arbitrary engine speed. CONSTITUTION:When a starter switch 4 is turned ON, the voltage at an S- terminal of a magnet starter 2 is raised to the battery voltage and residual voltage is generated even after the switch 4 is turned OFF. Here, since the voltage level for judging that a start signal is ON is set at a low value in an engine control unit 1, judgement is made by the control unit 1 that the start signal is ON even after the switch 4 is turned OFF. In order to overcome the above problem, the engine speed is detected by a crank-angle sensor 5, and the fuel- injection pulse width at the time of starting an engine if the detected engine speed is lower than an arbitrary speed N1. With such an arrangement, fuel is injected by the starting pulse width until the engine speed is raised to said arbitrary speed N1. Thus, it is enabled to prevent occurrence of engine-stall due to over-rich air-fuel mixture at the time of starting the engine.

Title: Terminal part of optical fiber
Inventor: HAYAKAWA KOICHI
IPC: G02B6/42
Filed: 1988-04-21
Abstract: PURPOSE:To prevent the return of the reflected light generated at the time of incidence or exit of light to the oscillation region of a light emitting element by forming the terminal of an optical fiber to a hemispherical by using an optical adhesive agent. CONSTITUTION:The terminal of the optical fiber 1 is formed of the optical adhesive agent 4 to the hemispherical shape and this adhesive agent layer 4 is disposed to face an LD (laser diode) 5. The light emitted from the LD 5 is partly irregularly reflected by the surface of the adhesive agent layer 4 and the remaining light enters the inside of the adhesive agent layer 4. The light is refracted in the hemispherical adhesive agent layer 4 and is condensed into a core 2 of the optical fiber 1. Since the adhesive agent has the refractive index equal to the refractive index of the core 2, the reflection of the light at the boundary face of the adhesive agent layer 4 and the core 2 is obviated. The incident light on the optical fiber or the exit light from the optical fiber is thus irregularly reflected by the end face of the optical fiber and the reflected light is no longer returned to the light emitting element.
