Title: Hydraulic brake controller for vehicle
Inventor: ARIKAWA TETSUO
IPC: B60T8/42
Filed: 1989-08-03
Abstract: PURPOSE:To prevent increase in piston push-in stroke at the time of braking slip control and prevent communication between a pressure source and a master cylinder at the time of switching over a valve device by constituting such a valve device that during drive slip control a hydraulic control valve side and a hydraulic pressure source are communicated so that fluid discharged from a hydraulic pump can be supplied to the hydraulic pressure source. CONSTITUTION:At the time of starting drive slip control, a solenoid Sa is first excited to switch a cut valve 42A to a cup position and then a solenoid Sb is excited to switch a cut valve 42B to a communicating position. Therefore simultaneous conduction states can be avoided, transmission of high pressure fluid from an accumulator 13 to a master cylinder 1 can be prevented, and damage of a seal, etc. in the master cylinder 1 can be prevented. In addition, discharged fluid in a hydraulic pump 41, that is, hydraulic fluid discharged from a wheel cylinder is returned into a main pipe of brake oil so that piston stroke of the master cylinder 1 can be securely prevented from being increased to full stroke.

IPC: H04L5/22
Filed: 1992-07-06
Abstract: PURPOSE:To provide the multiplex transmission method and its equipment in which synchronization is taken without giving redundancy to information to be sent and efficient information transmission is attained. CONSTITUTION:An area in which consecution of a same logic state is probably high is defined in advance as an inversion object area in transmission reception data. An area discrimination section 40 switches a selector 10 to send the inversion object area in transmission data to an encoder 20 and selects a selector 50 to send the inversion object area in the data fetched via a common bus 100 to a decoder 60. Logic inversion processing of even number bits is implemented in the encoder 20 and the decoder 60. Thus, even when same logic states are consecutive in the substantial transmission data, the data on the common bus 100 have frequent logic inversion and then synchronization is easily taken.

IPC: G03G15/05
Filed: 1984-09-27
Abstract: PURPOSE:To form the fine image having the resolution higher than the density of passage holes and high accuracy by providing an ion current modulating device which controls the ion current passing through the passage holes according to image information and oscillating the same in the direction where the passage holes are arranged. CONSTITUTION:When light is irradiated on a photoconductor layer 10, an electric field toward a common electrode 8 from an ion current control electrode 4 is formed in the ion passage holes 5 on the electrode 4 and the passage of the positive-polarity corona ions from a corona charger 11 toward the electrode 4 is blocked. The ion passage is assisted in the holes 5 connected to the layer 10 to which the light is not irradiated. An electrostatic latent image is therefore formed on a photosensitive body 1 when the light from an original surface is irradiated via a selfoc lens 18 to the layer 10. The density of the ion current control is doubled when a modulator 2 is oscillated toward arrow C direction by an exciting mechanism 20 consisting of magnets 21, 22 by which the formation of the fine image having the substantially good resolution and high accuracy is made possible.

Patent JP-S5993188-A (JP)
Title: Heat exchanger
Inventor: YANO NOBUYUKI
IPC: F24F3/14
Filed: 1982-11-17
Abstract: PURPOSE:To reduce the sliding sound of a rotor by a method wherein the rotor is rotated and a primary air current and a secondary air current change their flowing positions for each other periodically so that the heat storage capacity of the rotor is not saturated even when the rotational velocity of the rotor is reduced. CONSTITUTION:An air current B flows along a first element 4 and an air current A flows along a second element 5 at the upper surface of the rotor but the air current A flows along the first element 4 and the second air current B flows along the second element 5 at the lower surface of the rotor. Thus the air currents A and B change their flowing positions for each other repeatedly so that the latent heat stored in one of the elements 4 and 5 is transferred to the air current flowing along the other element. Consequently, due to the transfer of the latent heat through a partition wall 6, the heat storing capacity of each of the elements does not become saturated even when the rotor is held stationary by lowering the number of revolutions of the rotor.

Title: Quantization noise reducing device and bit length extending device
Inventor: TSUKAMOTO MASAKI
IPC: G11B20/10
Filed: 1998-07-02
Abstract: PROBLEM TO BE SOLVED: To reduce quantization noise component in a digital audio signal without deteriorating the sound quality of a music signal (audio signal) by detecting a high frequency band including up to a point where the average of time average powers exceeds the prescribed threshold as a quantization noise band. SOLUTION: A conversion means 1 converts the digital data which are divided in every block into the frequency axis components from the time base components. A level detection means 2 calculates the time average power of each frequency component and averages these time average powers in a specific range and in the frequency axis direction. A quantization noise detection means 3 successively compares the average of time average powers calculated by the means 2 with the threshold set previously from the high frequency bands toward the low frequency ones and decides the frequency bands exceeding the threshold as the quantization noises only. A level adjustment means 4 attenuates the level of a detected quantization noise band to reduce the quantization noise.

Title: Memory management device and computer-readable recording medium
Inventor: FUNATO NOBUHIKO
IPC: G06F12/16
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To actualize a garbage collection which is short in process time while prolonging the life of a rewrite-frequency limited type memory. SOLUTION: A stability setting part 12, sets the stability of a new object to 0 and the stability N of an object which is neither collected nor written while a garbage collecting process is performed by a specific number of times to (N+1). An object allocation part 14 allocates the objects of 0 and 1 in stability to a RAM 8 and allocates objects of 2 and 3 in stability to a flash memory 7. When there is no unused area, a garbage collection execution part 13 adds an area of higher stability from an area of 0 in stability and repeats the garbage collecting process. Thus, the frequency and time of the garbage collecting process are reduced and shortened to rewrites the flash memory 7 accompanying the garbage collection, thereby prolonging the life of the write-frequency limited type memory.

Title: Grounding position detecting method for winding of alternating-current equipment
Inventor: TABEI KUNIO
IPC: G01R31/34
Filed: 1986-08-29
Abstract: PURPOSE:To perform easy and accurate detection by connecting one terminal of a power source which is grounded at the other terminal through a current limiting resistance to the external connection terminal of winding, and measuring the earth current of a coil end part successively by a search coil. CONSTITUTION:The terminal of the single-phase AC power source 6 which is grounded at the other terminal through the current limiting resistance 6 is connected to the input terminal 2U of, for example, fixed winding 1U whose grounding position is to be detected while input terminals 2U-2W are held open. Then, the earth current IE is measured from the winding-start side coil end part of the winding 1U successively by the search coil 7. The current IE is relatively high until the grounding position is reached. Then the current IE becomes relatively low after the grounding part, so the current IE varies abruptly about the grounding position. Consequently, the coil end part where the current IE varies abruptly is detected as the grounding position.

Title: Tape recorder device
Inventor: YOKOYAMA HIDEO
IPC: G11B15/24
Filed: 1982-11-19
Abstract: PURPOSE:To prevent assuredly the deflection of a tape due to the revolution inertia of a flywheel, etc. when a tape is changed to a pause mode from a constant speed drive mode with a simple constitution, by providing a control mechanism which sets rotor in a non-transmission state of revolving power in response to the operation of a tape drive stop control member. CONSTITUTION:A high-speed slider 24 is slided downward with each operation of a quick traversing control plate, a rewind control plate and a temporary stop control plate respectively. Thus a constant speed gear 19f is separated from a constant speed gear 39 via a gear control slider 43 and a gear control lever 44 to prevent the transmission of the revolving power due to the inertia of a flywheel to the gear 19f. Therefore the drive of a micro-cassette tape is stopped immediately at a time moment when a stop control plate 27 is operated. This prevent the deflection of the tape.
