Patent JP-H0572530-A (JP)
Title: Back light unit
Inventor: KONO MASAO
IPC: G02F1/1335
Filed: 1991-09-12
Abstract: PURPOSE:To reduce the brightness unevenness by nearly equalizing the lengths of cables connecting plural fluorescent lamps and a substrate where their driving circuit is mounted. CONSTITUTION:Cold cathode discharge tubes CFL1 and CFL2 are arranged on a left and a right side in parallel across a light guide plate. The mounted substrate (power source for CFL) on which the driving circuit for turning ON the tubes is mounted is arranged on the right side of the light guide plate. When the power source for the CFLs is mounted on the right side of the panel, the wiring cable 1 for the CFL1 arranged on the right side opposite from it has the shortest size and the length of the wiring cable 2 for the CFL2 arranged on the right side is set matching the shortest length. In this constitution, the CFL1 and CFL2 which have uniform characteristics are selected and assembled to equalize the cables, to which they are connected, equal in length, thereby making floating capacity, etc., generated there by the easy means. The cables, therefore, become nearly equal in generated power loss and the CFLs illuminates with the same brightness.

Title: Method for judging loss of preceding vehicle in control system for distance between vehicles
Inventor: ONO DAISAKU
IPC: G08G1/16
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To reduce the time required for judgement by detecting relative speed and vehicle distance between its own vehicle and a preceding vehicle when the preceding vehicle is lost and changing the time for judging whether the preceding vehicle has been lost or not after the preceding vehicle was lost according to the speed and the distance for adjustment. SOLUTION: When target recognition is initiated (S1), it is judged whether radar beams capture a target, namely a preceding vehicle, or not. When it is judged that the preceding vehicle has not been captured, it is judged whether this is the first loss or not (S2). If it is judged that the preceding vehicle has been captured, 'a reference delay time' is set if the preceding vehicle deviates from beams temporarily (S3). Then, when the relative speed is minus, it is judged whether the preceding vehicle has been lost or not (S4). When it is judged that the preceding vehicle has been lost, a loss judgement delay time is set longer than a reference (S5). The loss judgement delay time is set longer than a reference time to judge whether the preceding vehicle has been positively lost or not (S6). Then, it is judged whether the preceding vehicle has been lost or not when the vehicle distance to the preceding vehicle is shorter than a specific value (S7) and then a judgement delay time is set longer than S6 (S8).

Inventor: KUSHIMA HITOSHI
IPC: H04N3/18
Filed: 1987-09-17
Abstract: PURPOSE:To prevent the operation of an X-ray protecting circuit or a circuit element from being destroyed with the rising of a high voltage by detecting a synchronization in a horizontal synchronizing signal out of specification and causing it to be uneffective. CONSTITUTION:When a horizontal synchronizing signal HS is inputted to a phase difference detecting circuit 1, a saw-tooth-wave is generated to the collec tor voltage of an output transistor Q1 of a horizontal output circuit 4 and im pressed to a yoke 5 and an FBT6. A comparator 9a of a comparing means 8 always compares a voltage, which is detected from the secondary side low voltage of the FBT6, with a reference voltage and when fluctuating quantity is over a prescribed value, a signal is sent to a breaking circuit 10 and a signal to be inputted is grounded or broken and made uneffective. When the regular signal HS is inputted, the operation of the X-ray protecting circuit 7 and the circuit element are prevented from being destroyed.

Title: Timer counter
Inventor: SUZUKI KAZUHIKO
IPC: G06F1/14
Filed: 1990-09-03
Abstract: PURPOSE:To select two kinds of operating modes as standard timer counter operation and extended timer counting operation by acting a storage means operated as a counter using a predetermined value as a compared value like a 2nd counter when extended time counting is required for and operating the 2nd counter in series with a 1st counter. CONSTITUTION:A 1st switching circuit 4 is turned on, a 2nd switching circuit 5 is changed over to receive an overflow output signal OF2 from a comparison value setting register 2 and a 3rd switching circuit 6 is changed over to receive an overflow signal OF1 from the counter 1 respectively. Thus, the comparison value setting register 2 is activated as a counter and the counter 1 receives an overflow output signal OF2 when the comparison value setting register 2 acts like a counter in place of a clock pulse. Thus, the comparison value setting register 2 and the counter 1 are connected in series, resulting that an equivalent counter whose bit length is doubled is realized.

Title: Television sound signal receiver
Inventor: BABA SUMIO
IPC: H04N5/60
Filed: 1985-10-18
Abstract: PURPOSE:To prevent display of a sound multiplex mode independently of external sound signals in a television sound signal receiver that switches and reproduces external sound signals and sound multiplex signals by making a display circuit system of a sound multiplex mode when reproducing external sound signals. CONSTITUTION:When a toggle switch for TV/video switching 36 is turned to video side, a switching signal is supplied from the output port 30c of a computer 30, and electronic switches 11, 12 and 21 are switched to the state of connection shown in the figure, and a picture formed by an external signal source appears in the picture of an image receiving tube 25. At the same time, sound caused by the external signal source is radiated from speakers 17 and 18. Simultaneously, the resistance value of an electronic variable register of a sound detector circuit 7 is increased by a switching signal from the computer 30 and output of the detector circuit 7 is cut off. Accordingly, judging signal is not outputted from a multiplex mode judging circuit 10. Therefore, a light emission diode 41 is not lit up, and characters that indicate a multiplex mode are not displayed independently of sound caused by the external signal source.

Title: Recording method of pcm signal
Inventor: ODAKA KENTAROU
IPC: G11B5/09
Filed: 1982-12-29
Abstract: PURPOSE:To record a signal without detecting the rotary phase of a head by adding address data to every specific sample of a PCM signal and recording a specific PCM signal after time-axis compression. CONSTITUTION:Address data is added to every specific sample of the PCM signal and a time-axis compressed PCM signal within a specific period is read out of a memory for time-axis compression repeatedly; and PCM data in optional sections corresponding to contacting periods of rotary heads 1A and 1B among those repeatedly read data is recorded as one track. Namely, when the PCM signal corresponding to the specific section is recorded, it is written in the memory correctly during reproduction by the added address data and the reproduced data need not be processed, so signals indicating the rotary phases of the recording heads 1A and 1B are unnecessary during recording. Thus, the signal is recorded without detecting the rotary phases of the heads.

Title: Nonvolatile semiconductor memory device
Inventor: WAKE SETSUO
IPC: H01L29/788
Filed: 1987-09-17
Abstract: PURPOSE:To improve writing characteristics of a nonvolatile semiconductor memory device having a floating electrode, by arranging the end surface of a high melting metal silicide film and the end surface of a polycrystalline silicon film, on the same line. CONSTITUTION:A high melting metal film 2 is made to encroach on the end surface of a resist by isotropic etching, and a polycrystalline silicon film 3 is subjected to isotropic etching to make the end surfaces of the films 3 and 2 in almost vertical form. Since, in the sectional form, the high melting metal silicide film 2 and the polycrystalline silicon film 3 are vertically etched, a contact area between a controlling electrode and a floating electrode is kept large, so that a capacitance C1 between the controlling electrode 2 and the floating electrode 4 becomes large. A voltage VPP applied to the controlling electrode 3 is divided by C and a capacitance C2 whose electrode are the floating electrode 4 and a P-pole silicon substrate 7. A voltage between the electrode 4 and the substrate 7, which determines writing efficiency, becomes large. Therefore electron based on avalanche phenomena generated between source and drain parts becomes easy to be implanted in the floating electrode, and writing characteristics are improved.

Abstract: PURPOSE:To drive a capacitive emitter at low d.c. power source voltage, and to reduce consumption power by connecting a drive circuit consisting of two coils and at least two switches, to an EL element, and by specifically controlling the ON/OFF operation of the switch. CONSTITUTION:A first switch means S1 is turned into ON condition from an OFF condition, and power is accumulated in a first inductor means L1, and the S1 is turned into OFF condition after a specific period of time passes, and the power of L1 is fed to and charged in a capacitive emitter EL. A process of accumulating the charged power of the emitter EL in a second inductor means L2, and a process of carrying out the same control for a second switch means S2 and for the circuit of the L2, to accumulate the charged power of the emitter EL in the L1, are also included. The two processes are repeated alternately or in partially the same time, by a controller. The power source voltage can be low, since part of the power accumulated in the emitter EL is returned to the L2, L1, and is re-used, and the power can thus be used effectively.

Title: Radar alitimeter having self-calibrating function
Inventor: JIEIMUZU AARU HAAGAA
IPC: G01S13/88
Filed: 1991-08-22
Abstract: PURPOSE: To increase the accuracy of a radar altimeter. CONSTITUTION: The radar altimeter includes a circuit for regulating reading of an altitude automatically in relation to fluctuations caused by changes in the altitude and temperature. Ordinary target tracking of a radar is interrupted intermittently and a calibration sequence is interposed. At each time point of interruption, the present altitude and receiver AGC information are stored temporarily and a test of introducing a false radar return at this altitude into a receiver is started. The receiver operates as if the false return were an actual return. A transmission power is regulated automatically by determining a correct signal level in tracking equipment.  Consequently, the altitude measured as to the false return is compared with a known test altitude, and when there is a difference between them, the difference is stored as a correction coefficient to be applied to the reading of the altitude stored at the time point when the operation is interrupted for executing the calibration test.

Abstract: PURPOSE:To improve frequency characteristics of a high frequency signal, specially, group delay characteristic and to prevent an electrode finger from being disconnected by putting a surface acoustic wave in phase at the output terminal of a surface acoustic wave converter with more precision, and propagating the wave. CONSTITUTION:Terminal points A and A' of electrode fingers 27 and 28 on the sides of buses 23 and 24 are regarded as coordinate origins. Further, terminal points B and B' are selected to remove dummy electrode finger parts outside two R curves A of ax<n> passing through A and B, and A' and B', and metallic plates 23A and 24A are arranged, but the other terminal part in the propagation direction is terminated by a curve B of bx<n>+c and a free surface is formed at the remaining part of a piezoelectric substrate as it is. In this case, a relation b=a-c is born among parameters. Consequently, the ratio of l1 and l2 is constant at any position on an (x) axis. When v-vm=DELTAvm and v-vp=DELTAvp, where v, vm and vp are propagation speeds of the free space part, metallic plate part, and electrode finger part, a point (c) on an (y) axis is calculated from DELTAvp/ DELTAvm=c/a.
