Patent JP-S60166814-A (JP)
Title: Encirclement type length or angle measuring device
Inventor: UARUTERU MIIRERU
IPC: G01D11/24
Filed: 1984-11-09
Abstract: An encapsulated length or angle measuring system includes a follower or a coupling member which extends through a slit in a housing of the measuring system. Thus slit is sealed off against harmful environmental influences by sealing elements which extend along the slit and are spread open by the coupling member in the region where the coupling member passes out of the housing through the slit. This spreading of the sealing elements can result in sealing problems. In order to provide better sealing, the sealing elements are formed as thin, resilient metal sheets which define chambers on their active sealing surfaces which contain a sealing fluid. This sealing fluid, by means of adhesion and capillary action on the follower or coupling member, seals off the extremely fine gaps which are typically present between the follower or coupling member and the sealing lips.

Title: Common flow passage for heat exchanging fluids
Inventor: AKACHI HISATERU
IPC: F28D15/02
Filed: 1983-12-13
Abstract: PURPOSE:To achieve an efficient heat exchanging by constructing a common flow passage comprising three sections of a heat exchanging flow passage section, and a high speed fluid flow passage section and a low speed fluid flow passage section which are mutually connected by said heat exchanging flow passage, in which the fluid that has completed the heat exchange does not adversely affect the downstream side. CONSTITUTION:A common passage is divided into three sections of a low speed fluid flow passage 8, a high speed fluid flow passage 9 and multiple heat exchanging flow passages 10 that connected the former two. When a fluid passes through a passage constructed in this manner, the static pressure in the high speed fluid pressure becomes relatively lower than the static pressure in the low speed fluid passage, and as a result, the low speed fluid is drawn to pass over the heat exchanging passage as it exchanges the heat, and merges the high speed fluid. Therefore, there is no distinction as upstream or downstream between heat pipes 1, 2, and each of them directly exchanges the heat with the fluid 5 before the heat exchange, and so, there is no reduction in the heat exchanging efficiency.

Title: Micro dimension measuring device
Inventor: KOSUGE SHOGO
IPC: G06T1/00
Filed: 1993-08-27
Abstract: PURPOSE:To vertically operate an X-axial stage, accumulate and compose the image signal of the focused image for every measuring position without operating an auto focus, simplify the operation, and shorten the measuring time. CONSTITUTION:When a measurement is started, a TV camera 4 picks up the image of a subject 2 to be measured. An image memory 6 compares the input signal of a differential image signal V' in which absolute values are taken every picture element with the signal held thereby at that point of time, and newly holds a high illuminance level signal. This is repeated until the Z-axial stage 1 moves to positions Z1-ZN and finishes the measuring operation. While the state 1 is within the range from the position Z1 to this side of the position ZA, the signal V' is of low level, and the accumulated composed image signal of the memory 6 is also of low level. The signal V' and the accumulated composed image signal are focused to faces FA, FB in positions ZA, ZB, and become signals having distinct peak waveforms. When the measurement operation is finished, the memory 6 outputs the illuminance signal level held thereby as the accumulated composed image signal, and a measurement processing part 7 measures a required width of the subject 2 from the relative positions of the peak waveforms having high illuminance levels.

Title: Photosensor device
Inventor: YAMANE TOSHIAKI
IPC: G01R15/24
Filed: 1987-09-19
Abstract: PURPOSE:To execute the measurement with high accuracy, even if the number of pieces of photosensors increases by integrating a sensor signal which is received in a photodetecting device and deriving all the energy of a pulse. CONSTITUTION:An optical pulse outputted from an optical pulse generator 1 having a coherent light source such as a laser diode, etc., is transmitted through an optical fiber 3, an optical pulse which is allowed to transmit through photosensors 13a-13n or reflected is photodetected by an optical receiver 6, and physical and electrical variations of the outside working on the photosensors 13a-13n are measured. Subsequently, the optical pulse photodetected by the optical receiver 6 is converted to an electric pulse and transmitted to an amplifier 7 and amplified, so as to output to an integrator 16. This integrator 16 integrates the inputted pulse by a longer time constant than pulse width, holds a peak value and brings it to A/D conversion by a signal processor 8, and outputs it to a display device 9. The integrator 16 derives all the energy of the optical pulse, holds the peak and brings it to A/D conversion by the signal processor 8, therefore, the influence of a model noise can be eliminated, and the S/N is improved.

Title: Signal input circuit
Inventor: OKAMOTO YASUYUKI
IPC: H01L27/10
Filed: 1992-08-11
Abstract: PURPOSE:To speed up the transmission of a write end signal to an internal circuit by providing this signal input circuit with a control circuit for switching the connection/disconnection of a switch circuit by a delay signal of an internal signal. CONSTITUTION:An address input circuit 101 is constituted of a switch circuit 101a for passing or interrupting an address signal and a latching/passing circuit 101b capable of switching the output of the circuit 101a to a latching state and a passing state. When a write activating signal is inputted to a write input circuit 102, the circuit 101b is switched from the signal passing state to the signal latchable state by an internal signal corresponding to the activating circuit and the switch circuit 101a is switched from the conductive state to the non-conductive state by the delay signal of the internal signal. Thereby a change in the address signal can be held in an output terminal 2 independently of the signal level state of an input terminal 1 and the settlement of an error address due to an address signal with a noise can be prevented.

IPC: G02F1/13
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To prevent light leakage without a complex manufacturing process. SOLUTION: A color filter is formed by forming a light shielding layer on one substrate (101, 102) and by coating and patterning a color layer film (103, 104). Subsequently an ITO(indium tin oxide) film is formed (105) and is patterned to form a transparent electrode and a reference mark simultaneously (106). Furthermore an alignment film is formed (107). Thus a color filter substrate is completed. A driving element incorporating TFT is formed on the other substrate (108), thereon a reference mark and an alignment film are formed (109, 110) to complete a TFT(thin film transistor) substrate. Subsequently the color filter substrate and the TFT substrate are placed opposite to each other and are optically positioned by superposing the reference marks with each other (111).  After the positioning is finished, adhesion with a sealant 20 is done (112) and liquid crystal is enclosed therein (113).

Title: Automatic document feeder
Inventor: IMOTO SHINJI
IPC: G03G15/00
Filed: 1999-08-24
Abstract: PROBLEM TO BE SOLVED: To prevent the distortion of a copied image caused by the dispersion of document speed by reducing the carrying force when the trailing edge of a document goes through a roller stepwise, dispersing the sudden change of feeding force when the trailing edge of the document goes through in the axial direction and restraining the unevenness of carrying speed to the minimum in the case of ejecting the document from an exposure part. SOLUTION: As for a carrying roller 43 and a pressure roller 41 carrying the document to the exposure part, the difference of distance from the pressure roller 41 to each exposure position is given to the pressure roller group 41 nearest to the exposure position (41-e<41-c or the like). Thus, the sudden change of the feeding force is restrained and the distortion of the copied image is prevented.

Title: Transition current detection device
Inventor: YAMAGUCHI HIROAKI
IPC: H01F38/28
Filed: 1990-09-07
Abstract: PURPOSE:To obtain induction current for tracking transition current by retaining one part of an electric wire in parallel with a conductor adjacently with a screening material which is mounted to the conductor and then providing the electric wire at an outer periphery of the screening material. CONSTITUTION:When transition current is allowed to flow to a conductor 5, a magnetic field F is generated at its periphery and an electric wire 8 is retained in parallel with the conductor 5 and adjacently, thus allowing induction current to flow to the electric wire 8. Influence of the magnetic field F which the electric wire 8 receives (influence of the magnetic field F in the electric wire 8 at areas other than a part which is in parallel with the conductor 5 and is retained at an adjacent state is reduced by screening effect of a screening material 7 and is ignored) is proportional to a length l of the electric wire and is inversely proportional to a distance r so that transition current can be detected always with a constant accuracy by fixing the length l of the electric wire and the distance r. The detection circuit is only the electric wire 8, inductance becomes extremely small, and an induction current (detection current) 12 can be obtained tracking the transition current 11 rapidly.

Title: Small-sized radio communication system
Inventor: FUENTES JAMES JOSEPH
IPC: H04B7/26
Filed: 1993-09-24
Abstract: PURPOSE: To obtain a compact and inexpensive communication system by directly connecting the transceiver of a cell base station with another transceiver as a pair, and assigning it to a calling station and a called station. CONSTITUTION: A radio cell base station 1 communicates with mobile stations 8 and 35, and this is provided with transceiver groups 2-5 under the control of a processor 10, and the transceivers are mutually connected with the different groups by wire connection. A protocol converter/processor 60 selects the properly selected transceivers, and controls the setting of radio connection. For example, when a request for connection from the mobile station 8 to the mobile station 35 is transmitted, the processor 10 receives a signal from the mobile station 8 which requests the connection, and the protocol converter/processor 60 analyzes a called telephone number, and recognizes that it is the telephone number of the mobile station 35, and that the communication can be attained through the radio connection of the group 3.  Thus, a pair from the radio connection of the groups 2 and 3 mutually connected by wire connection are selected.
