Abstract: PURPOSE: To manufacture main rotors of various shapes at various tolerances with one cutter by fitting the cutter rotatable about its axis so that the plane thereof is parallel to the rotor body longitudinal axis and so that the cutter rotational axis is perpendicular to the rotor longitudinal axis. CONSTITUTION: A cylindrical rotor body 60 to be machined is fitted to a shaft 62 rotatably supported on a bracket 64, a cutter 68 is fitted to a shaft 70 having the axis perpendicular to the axis of the shaft 62, and a gear box 72 rotates the cutter 68 around the shaft 70.

Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To accurately discriminate between the passage and stay of a person so as to consume less power when the person is determined to pass than when the person is determined to stay and to provide sufficient illumination when the person stays.

Title: Suction valve controller for engine
Inventor: IKEDA YOSHITO
IPC: F02B31/02
Filed: 1984-12-10
Abstract: PURPOSE:To improve engine output in times of medium and low speeds, by forming a suction port of an engine, installing two suction valves in one cylinder, asymmetrically to each suction valve, while quickening closing timing of the suction valve at the side where a swirl is liable to be produced reversely to the suction direction. CONSTITUTION:A suction port 3 of an engine, installing two suction valves 1 and 2 in one cylinder 4, is formed asymmetrically to these suction valves 1 and 2. In time of valve opening in these valves 1 and 2, especially suction air at the side of the valve 1 strongly flows into the inside of the cylinder 4 whereby a swirl consisting of an air flow as shown in a full line is produced inside the cylinder 4. With this swirl, blowing back of the suction air from the side of the valve 2 is going to be produced inside the port 3, but valve opening timing at the side of the valve 2 is made quicker than that of the valve 1 whereby the blowing back is in no case produced there, thus an air flow as in a dotted line is produced.

Filed: 1990-09-28
Abstract: PURPOSE:To always achieve an appropriate grilled finish by a method wherein a heating operation is stopped a specified time period after the peak of steam generation is detected and then a specified amount of steam is generated. CONSTITUTION:When food to be cooked is heated by upper and lower heaters 4 and 5, the radiant heat of the heaters acts directly on the surface and steam is generated mainly from the surface of the food. During heating, an operating control circuit 10 always reads detected signals from a sensor 9 and detects a peak point of steam generation where the change rate of the signals reaches 0. After that, the operating control circuit 10 still continues to read signals from the sensor 9 to judges whether or not the steam generation amount reaches the specified value. Steam generation reaches the peak at the time tb and diminishes to almost nil at the time tc. Time count is started from the time tc and when a specified time period elapses, heating operation is stopped.

Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To manufacture an optical fiber coupling device low in cost. SOLUTION: In this unidirectional or bidirectional optical fiber coupler which uses POF(polymer optical fibers) having a mirror 210 in themselves so as to reflect a light signal, the mirror has >=1 cut part 240 having >=1 surface reflecting a light signal perpendicular to the center axis of the fiber at an angle to the center axis of the optical fiber.

With a bidirectional implementation style, the light signal from a tap fiber can be reflected in an opposite direction along a 1st optical fiber, i.e., a bus optical fiber. With another style, the depth of a cut part 240 is controlled by monitoring the residual power from the optical fiber during the cutting of the cut part.
