Patent JP-H08301093-A (JP)
Title: Antiskid controller
Inventor: WATANABE TAKASHI
IPC: B60T8/48
Filed: 1995-05-11
Abstract: PURPOSE: To lower as far as possible the depressurization-possible-pressure with regard to the wheel cylinder pressure by providing a discharge adjusting means, which decreases the discharge of a brake fluid from a pump, when the pressure intensifying control is unnecessary to any wheel cylinder which is to be controlled by an antiskid controlling means. CONSTITUTION: In antiskid control, the slipping condition of a wheel is controlled to an optimum condition. Especially in a low-μ(-value)-road like on the ice, the wheel cylinder pressure should be made as low as possible. Here, the depressurization-possible-pressure is obtained by adding the pulsating pressure of a pump discharge to the back pressure of reservoirs 25, 26. By turning a motor OFF in order to stop (bring the discharge to 'zero') the discharge of the brake fluid from pumps 9, 10, the pressure equal to the pulsating pressure due to the pump discharge can be lowered. As a result, the depressurization- possible-pressure can be lowered. Accordingly, this is advantageous for the pressurization control when a car runs on the low-μ(-value)-road.

Title: Heat exchanger* particularly recuperator for high temperature nuclear reactor
Inventor: HAINTSU FUISHIYURI
IPC: F28D7/16
Filed: 1978-09-14
Abstract: A heat exchanger, especially recuperator for high temperature reactors, comprising a prismatic extending jacket and a multiplicity of elongated hexagonal elements arranged within the jacket and essentially parallel to the primary direction or extent thereof. Each hexagonal element has a central tube and heat transfer surfaces arranged about each central tube and extending axially up to the outer contour or outline of the corresponding hexagonal element. Both ends of the heat transfer surfaces are connected to collectors seated upon the central tube. Each hexagonal element is connected by spacers with its neighboring elements and with analogous spacers spatially fixedly arranged at the region of the jacket laterally bounding the heat exchanger. The spacers have play so that the spacing between the elements and between the elements and the spatially fixedly arranged spacers can alter by the amount of such play. This play is dimensioned such that the sum of the play in any one respective direction over the cross-section of the heat exchanger still positively takes up without constraint the greatest differential expansion arising between the package of hexagonal elements and the spatially fixedly arranged spacers in such direction under extreme operating conditions.

Title: Distribution system for attendant board incoming call
Inventor: TAMURA MASAHIKO
IPC: H04M7/00
Filed: 1990-04-27
Abstract: PURPOSE:To attain detailed distribution by combining caller subscriber information distributing an attendant board incoming call and dial information representing a request service content. CONSTITUTION:Subscriber line exchanges (LS) 1-3 accommodating subscribers located in a thickly populated area are connected to a trunk exchange TS 4 located similarly in the thickly populated area. Then a reference table between a control operation center number and a caller subscriber number stored in a memory of an exchange in advance is compared with an entered dialed subscriber number 8 at a distribution destination operation center selection means 12 of an control section 11 to extract the distribution destination operation center number. Then an idle attendant board satisfying a dial number 9 offering the service requested from the subscriber is selected among idle exchange boards selected by the distribution destination operation center selection means 12 from a distribution destination selection means 13 and the selected number is outputted. Thus, calls are distributed in details.

IPC: F02B3/06
Filed: 1987-05-12
Abstract: PURPOSE:To prevent the jumping phenomenon by installing a spring for urging a locker arm for driving a unit injector to a cam side and a return spring for urging the plunger of the injector to the projection direction against the spring. CONSTITUTION:As for an internal combustion engine, e.g., diesel engine 1, the pump part 24 of an L-shaped unit injector 23 is moved in reciprocation through an injector driving locker arm 22. In this case, the slipper 22c of the locker arm 22 is always pressed to an injector driving cam 18 by a coil spring 50 for attaching a cam. Further, a roller 36 at the top edge of the plunger is pressed to the pressing piece 22d of the locker arm 22 by a return spring arranged in the pump part 24. Therefore, even if the engine 1 revolves at a high speed, the separation of the slipper 22c from the cam 18 and the separation of the pressing piece 22d from the roller 36 can be prevented, and the jumping phenomenon can be prevented.

IPC: G10L15/00
Filed: 1983-06-23
Abstract: PURPOSE:To recognize an aural signal and transmit the recognized result from a transmitting circuit to a receiving circuit after coding the recognized sound signal, by decoding the coded signal and transmitting the decoded signal after converting the decoded signal into a serial pulse string signal through a matrix circuit. CONSTITUTION:Data corresponding to language are previously stored in a speech recognizing board E1. Moreover, the speech recognizing board E1 compares an aural signal inputted from a microphone 23 with the previously stored data and, when they coincide with each other, sends out data corresponding to the inputted aural signal as a code signal which is then decoded at a decoder circuit D. At a matrix circuit C, a photocoupler corresponding to the output signal from the decoder circuit D is turned on. A pulse string output circuit B2 sends out pulse signals corresponding to signals given from the matrix circuit C to terminals DT1- DT4 and KY1-KY8 as pulse string signals from its terminal OUT and gives the pulse string signals to an output terminal 14 through a transistor 11.

Title: Speed detecting method for electric motor
Inventor: SANO KIMINORI
IPC: G01D5/245
Filed: 1989-05-09
Abstract: PURPOSE:To accurately calculate a rotating speed when a rotating direction is switched by generating the rotation directional identification signal of the electric motor from plural sets of PG pulse trains which have different phase angles with one another and generating a counter clear signal at the time of direction inversion. CONSTITUTION:A control signal generating circuit 4 receives the rotation directional identification signal fU/D generated by a direction identifying circuit 3, a pulse train PG3, and a reference clock pulse train Pd having a specific clock period Tc and generates counter clear signals fc1 and fc3 when the rotation direction of the electric motor is switched. When a measurement mode signal fm indicates a fast mode, a CPU 11 calculates the absolute value ¦Fm¦ of the rotating speed from ¦Fm¦=(C1-1)/(C2-C3)Tc by using counted values C1, C2, and C3 of counters 5, 7, and 9 held by counter latch circuits 6, 8, and 10. In slow mode, on the other hand, ¦Fm¦=1/C4Tc is calculated by using a counted value C4 held by the counter latch circuit 10 to calculate the accurate speed even when the rotation of the electric motor is switched.

Abstract: PURPOSE:To improve operability by detecting that a mouse is separated from an operation face and obtaining the moving speed of the mouse just before this separation to move a cursor. CONSTITUTION:A mouse 11 which moves the cursor on a screen is provided with a movement extent detecting part 12, a moving speed operating part 13, and a separation detecting part 14 which detects that the mouse 11 is separated from the operation face. A processing part 15 which controls the movement of the cursor consists of a movement extent operating part 16 which obtains the extent of movement of the cursor at the time of non-detection of said separation detecting part 14, a storage part 17 in which the moving speed obtained by the moving speed operating part 13 is stored, a temporary movement operating part 18, a cursor moving part 19, and a control part 20 for these parts. When it is detected that the mouse 11 is separated from the operation face, the moving speed of the mouse just before this detection is obtained and the cursor on the screen is moved by an extent corresponding to this speed. Thus, the number of times of separation of the mouse 11 from the operation face is reduced to shorten the movement time of the same distance.
