Title: Lighting fixture for vehicle
Inventor: AKIYAMA ICHIRO
IPC: F21Y101/00
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To provide a lighting fixture for vehicle which can generate an ideal light distribution pattern. SOLUTION: A first reflecting surface 61 consists of a rotational paraboloid where a focal distance f1 is greater than a focal distance (f) of the virtual rotational paraboloid and a focal point F is positioned identical to the focal point F of the virtual rotational paraboloid. A second reflecting surface 62 consists of a rotational paraboloid where a focal distance f2 is smaller than a focal distance (f) of the virtual rotational paraboloid and the focal point F is positioned identical to the focus F of the virtual rotational paraboloid.  As a result, the spreading width of the reflected light by the first reflecting surface 61 becomes smaller than that of the reflected light by the virtual rotational paraboloid to approach the spreading width of the reflected light where the ideal light distribution pattern is obtained, while the spreading width of the reflected light by the second reflecting surface 62 becomes greater than that of the reflected light by the virtual rotational paraboloid to approach the spreading width of the reflected light where the ideal light distribution pattern is obtained. Accordingly the ideal light distribution pattern is obtained even if the direction of the reflecting surface axis Z-Z differs from the direction of the light source bulb axis B-B.

Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To miniaturize a detector and to continuously detect an optional level with a high precision by extending an optical fiber in a liquid, and detecting the light that reaches the tip part of the optical fiber while successively reflected by the inner wall, and is reflected by the tip part and returned while successively reflected. SOLUTION: A level detecting sensor 80 comprises a sensor body 83 having a light emitting part 81 and a light receiving part 32, and an optical fiber 84 extended from the sensor body 83 to a liquid, the optical fiber 84 having a reflecting surface 84 formed on the tip. The light emitted from the light emitting part 81 toward the inner wall of the optical fiber 84 reaches the tip part while successively reflected by the inner wall, reflected by the reflecting surface 85, and returned to the sensor body 83 while successively reflected by the inner wall, and detected by the light receiving part 82. The refractive index of the inner wall of the optical fiber 84 is varied between the part exposed to a liquid and a part exposed to air, and according to this, the intensity of the reflected light is changed. Thus, the intensity of the reflected light changed following the change of liquid level is detected by the light receiving part 82, whereby an optional liquid level can be continuously analogously detected.

Title: Microcomputer system
Inventor: SUNAGA YUKIO
IPC: G06F13/38
Filed: 1991-04-20
Abstract: PURPOSE:To restart the internal process of a CPU board even in the absence of a connection confirmation signal input due to the omission of the I/O board by outputting an overtime signal to the CPU by the 1st timer circuit in the CPU board instead of the connection confirmation signal. CONSTITUTION:The signal holding circuit 15 of the CPU board 10 sends out a connection holding signal when a connection path 34 is connected and closes a gate circuit 16 when not. A selector circuit 13 transfers the connection holding signal 43 as an operation inhibition signal 44 by referring to an I/O request signal 41 and an I/O address. A timer circuit 14 starts time-limit measurement by referring to the I/O request signal unless the operation inhibition signal 44 is being received, and inputs time-limit overtime signals 45 and 48 to the interruption signal input and operation permission signal 44 of the CPU 11 a specific time later. A timer circuit 17 operates similarly as mentioned above and quits the time-limit measurement on inputting the time-limit overtime signals 45 and 48 from the timer circuit 14 or the connection confirmation signal 42 from the I/O board 20.

Abstract: PURPOSE:To reduce the generation of noise, by attaining a reduction of pressure with a working mechanism that applies a working pressure to a bellows with the dynamic pressure of a fluid itself and giving a balance to the bellows so that it keep an opening appropriate to a flow. CONSTITUTION:A bellows 4 is provided at a port part to extend from a fixed end 10' and then presses with a free control the gap between the port part and a sheet part. when a working pressure having a relation of P1>P2>P3 is applied to the bellows 4, a downward force to press the port part down by the pressure P2 is applied to a pilot governor secondary room 19 through a tube 22. And a balance is obtained at a certain position between the push-up force and the push-down force. Both the balancing position and the working pressure P2 are decided by the primary side pressure P1 and the secondary side pressure P3 plus the flow rate of gas which flows at that moment. When the pressure P3 is higher than the set value, the pressure P2 becomes high to increase the force that pressed the port part down via the function of a pilot valve with which a part of the fluid works in division.
