Title: Illuminator for liquid crystal display device
Inventor: MATSUMOTO KENJI
IPC: G02F1/1335
Filed: 1988-01-26
Abstract: PURPOSE:To enhance light utilizing efficiency by totally reflecting light from a light source with the collection of the parabolic reflecting surfaces of the bottoms of photoconductors, and deflecting the light in the front surface direction of a light crystal panel with the collection of the fine reflecting surfaces provided on the top of the photoconductor. CONSTITUTION:The light from a light source 1 is totally reflected by the collection of parabolic reflecting surfaces of the bottom of photoconductors 17, approximately converted into parallel light, and next, deflected in the front surface direction of a liquid crystal panel 8 by the collection of fine reflecting surfaces 6 provided on the top of the photoconductor 17. In such a way, by utilizing the two reflecting surfaces and conducting the light, the width of the photoconductor 17 is made thinner. In such a case, however, the light is not conducted into the two areas illuminated on the liquid crystal panel 8 by the two adjacent parabolic reflecting surfaces, and luminance unevenness is generated. There, when a photoconductor 18 consists of first and second photoconductive members 2 and 3, the transparent light is totally reflected on a second reflection surface 11, and conducted to the area where the light is not conducted by a first reflecting surface 10, a diffusion plate is unnecessary, and the light utilizing efficiency is enhanced.

Title: Parallel processing method
Inventor: MURATA OSAMU
IPC: G06F9/46
Filed: 1991-01-11
Abstract: PURPOSE:To improve the overall processing speed by using an independent 1st CPU to perform the approximately periodical input processing in order to reduce the processing burden of a 2nd CPU. CONSTITUTION:A mailbox IC 3 consists of a RAM, for example, and writes the sensor output change data given from a 1st CPU 1 into a prescribed address corresponding previously to each sensor. A 2nd CPU 2 receives an external interruption signal from the CPU 1 and an address that is updated with the data on the IC 3. Then an address is designated for the IC 3 through the received address. Thus the data are read and then fetched and processed as the external input data. As a result, the CPU 2 just has to receive the sensor output that has been processed by the CPU 1 and therefore never receives the influence of the input processing.

Title: Semiconductor integrated circuit device
Inventor: HATTORI KOJI
IPC: H01L27/04
Filed: 1990-01-23
Abstract: PURPOSE:To output reliably an autoclear pulse and to prevent the erroneous operation, which is caused by a chattering, of a power supply from being gener ated by a method wherein when the power supply is changed from an ON-state to an OFF-state, the stored charge in a gate electrode is immediately discharged to the power supply via a diode. CONSTITUTION:When a power supply is changed from an OFF-state to an ON-state immediately after being changed from an ON-state to an OFF-state, a potential of a cathode 8b of a diode 8 becomes lower than that of an anode 8a of the diode 8 and a charge transfer via the diode 8 is generated. Thereby, a stored charge in a node A is immediately emitted to the side of the power supply. As a result, an N channel MOSFET 2 is immediately turned-OFF and subsequently, a P-channel MOSFET 4 is turned-OFF. After that, a potential of the node A rises and when the FET 4 is turned-ON, an inverter 7 is actuated. As a result, even if the power supply is changed from an ON state to an OFF- state and immediately changed to an ON-state, an autoclear pulse is outputted in a normal state.

At the time of deciding whether or not one key is stored in this system, the plural hash addresses in which the hash function is added to the sub-part of a test record are generated. The key for the test record is compared with the key stored in each generated hash address. When the key for the test record is sufficiently close to any key in the hash address, it is judged that the test record is stored in the system.

Title: Very small pore parallelism measuring method of connecting parts for optical fiber
Inventor: SATOU HIROCHIKA
IPC: G02B6/24
Filed: 1983-02-01
Abstract: PURPOSE:To measure a very small pore parallelism without holding an optical fiber by irradiating plural through-otical beams which are emitted through a very small pore and have each different advancing directions, to an optical sensor for converting an image of light of a photodetecting surface to a picture signal, and detecting a distance between the through-optical beams. CONSTITUTION:When there is no incompleteness of a very small pore parallelism in a ferrule, an optical beam 20 passing through a capillary 6 goes straight on 12 as it is and reaches a screen 15. In this case, a plane image generated on the screen becomes 14 and 14. On the other hand, when a bent angle exists in the connector, a part of the optical beam 20 passing through the capillary 6 goes straight on 12 as it is and reaches the screen 15, but the other beam is reflected by the inside surface of the capillary once, changes 13 its course and reaches the screen 15. A plane image on the screen in this case becomes 17 and 18. In this case, 17 is formed by straight light, 18 is formed by reflected light, and an inter-image distance measured on a line 19 where the inter-image distance becomes largest is denoted as X. That is to say, the very small hole parallelism is converted to position information X by only irradiating a parallel beam.
