Inventor: SATO MAKOTO
IPC: G01B11/26
Filed: 1986-06-20
Abstract: PURPOSE:To easily take a high-accuracy measurement by a simple device by irradiating a screen with light projected from an end of an optical fiber to be measured through a transparent glass plate and measuring the distance between the center of a formed projection image and the center of a concentric interference image. CONSTITUTION:The end 1b of the optical fiber 1 to be measured is fixed to a fixed base 4 and the transparent glass plate 2 which has uniform thickness is provided at optional distance from the fixed base 4. Further, an image pickup device 3 which has the screen 3a is provided opposite the fixed base 4 across the glass plate 2. The glass plate 2 and screen 3a cross the axis of the optical fiber 1 at right angle. Then, the light projected from the end surface of the optical fiber 1 to be measured is projected on the screen 3a through the glass plate 2 and the distance between the center of the projection image formed on the screen 3a and the center of the concentric interference image formed on the screen 3a over said projection image is measured to calculate the end surface angle of the end of the optical fiber 1 to be measured from the obtained distance.

Title: Seat equipped with fatique relaxing apparatus
Inventor: EMA KIYOO
IPC: A47C7/14
Filed: 1987-06-08
Abstract: PURPOSE:To reduce the oppressive sensation of a seat by forming partial spaces to the parts brought into contact with the waist and the back, by pressurizing or decompressing the arbitrary air chamber among a plurality of the air chambers provided to the seat part and backrest part of the seat. CONSTITUTION:For example, the air chamber 3a-3n of a fatique relaxing seat 3 are divided into four groups I-IV. When 20sec is elapsed after the supply of air to all of the air chamber 3a 3n was started, the three-way solenoid valve connected to piping 4a changed over to be opened to the atmosphere and the air chambers 3a, 3e,... of the group I are decompressed to the atmospheric pressure for 10sec while the air chambers of the other groups II, III, IV are held to an expanded state and the surface of the corresponding part of the air chamber 3e of the group I is depressed. After the group I is decompressed for 10 sec, the three-way solenoid valve of the group I is changed over to supply the compressed air of a tank 9 to the piping 4a and the air chamber 3a, 3e,... of the group I are pressurized to return the fatique relaxing seat 3 to the original state. By this method, the air chambers 3a-3n are selectively pressurized or decompressed at every predetermined time to change the contact parts of a seat part 2a and a backrest part at every definite time.

Title: Vane compressor
Inventor: IIO MASAHIRO
IPC: F04C28/10
Filed: 1980-10-14
Abstract: PURPOSE: To minimize energy loss caused at the time of starting a vane compressor used in an air-conditioning system for a vehicle or the like, by lowering the compression power automatically at the time of high-speed operation of the compressor, and thereby decreasing the on-off switching frequency of the compressor.  
     CONSTITUTION: A vane compressor shown in the drawing compresses coolant introduced from an inlet port 9 and then discharges the same to the outside of a pump chamber 7 along with increasing and decreasing of the volume of the pump chamber 7. Here, a suction port 11 is formed at the part of a side block 2 facing a coolant suction chamber 8, and a slidable member 12 is disposed in the port 11. The slidable member 12 is urged radially outwards by the force of a spring 13 when the compressor is stopped or operated at a low or medium speed but moved radially inwards by the force of the spring 13 as the speed of the compressor is increased. Since, in this state, the distance d between the slidable member 12 and rotor 4 is decreased, coolant in a groove 4a communicated to a slit 5 is allowed to flow into the pump chamber 7, so that the compression power of the compressor is lowered.

Title: Dynamic random access memory device
Inventor: TANIZAKI TETSUSHI
IPC: G11C11/401
Filed: 1992-06-04
Abstract: PURPOSE:To shorten a time required for a self-refresh function confirming test by using a clock signal having a higher frequency than that in a normal self-refresh mode. CONSTITUTION:When the self-refresh function confirming test is executed, a test mode designation signal in a higher voltage level than a power supply voltage Vcc is applied to a terminal 22. A test mode detecting circuit 19 outputs a test mode signal CTE in a high level in response to a high voltage applied to the terminal 22. Transmission gates 17 and 18 are turned-on and off in response to the signal CTE. Therefore, a clock signal phit having the higher frequency generated from an oscillation circuit 16 is applied through a gate 18 to a refresh counter 14 as a signal phic. As the result, a refresh address signal REF having a shorter refresh cycle than that in the normal self-refresh mode can be generated from the counter 14.

Filed: 1990-05-31
Abstract: PURPOSE:To reduce the visual field of a television camera by providing an inspection means to inspect a material to be measured integrally with the television camera. CONSTITUTION:A control circuit 30 responds to output from an image processing circuit 14, and judges whether or not the neighboring next new mark for positioning in the visual field is detected, and the circuit 30 switches the common contact 24 of a change-over switch 20 to an individual contact 21. Thereby, a servo motor 11 is a driven so as to set the neighboring next new mark for positioning at a position set by a setting circuit 18 in the visual field. Thus, since the visual field of the television camera 4 can be comparatively reduced, it is possible to set the mark for high positioning at the position decided with high accuracy in the visual field. Therefore, it is possible to measure a desired position sequentially and with high accuracy by a flux meter.
