Title: Automatic answering telephone system
Inventor: KAWAMURA TAKU
IPC: H04M1/65
Filed: 1990-01-17
Abstract: PURPOSE:To allow the user to surely listen to a message by devising the set such that reproduction is automatically started when a travelling object detection means detects return of a user who is a travelling object. CONSTITUTION:When the user returns home and enters a room, an ultrasonic wave pulse radiating from an ultrasonic wave transmitter 11 is reflected in the user near the ultrasonic wave transmitter than a main reflecting body and returns to an ultrasonic wave transmitter 12, then the time of the arrival to its peak is shorter than a mean value during the absence of the user. Then a control means 10 activates a message recording/reproduction means 7 to rewind a magnetic tape 8 till a set initial position and to reproduce a message recorded during the absence. Thus, the user does not require any key entry operation and a mistake leaving the reproduction of a message undone is prevented.

Title: Hydraulic pressure control system for multi-system brake
Inventor: KONDOU TOSHIYUKI
IPC: B60T8/40
Filed: 1978-01-26
Abstract: PURPOSE: To eliminate the malfunction of a cut-off valve within a control valve means and improve the safety by electrically connecting the cut-off valve to an antiskid actuator operating means.  
     CONSTITUTION: When a sensor senses a skidding state and produces a signal, a pneumatic directional control valve 200 is switched in response to that signal. As a result, a power piston 140 in an actuator is moved to the left with the pressure difference between changes 160 and 150, whereby a cut-off valve 110 is moved to a cut-off position. In an interlocked relation to the switching action of the pneumatic directional control valve 200 a switch 210 is closed, while at the same time the power piston 140 is moved to the left to turn "on" a switch 180. Since the switch 180 is "on" during the antiskid action, a solenoid 431 is held excited irrespective of the repeated "on"-and-"off" operation of the switch 210 interlocked to the pneumatic directional control valve 200, and thus a ball valve of a control valve means holds its cut-off state and thus prevents pressure variations from occurring.

Title: Measurement method for particle size distribution by light penetration deposition method
Inventor: SUJITA SHIGEKO
IPC: G01N15/04
Filed: 1992-01-21
Abstract: PURPOSE:To enable exactly measuring particle size distribution even for suspension with large light penetration rate and small light absorption by adding a solvent having a different refractive index from that of the measured object particles. CONSTITUTION:In the suspension 2 in a deposition pipe 1, a solvent having a different refractive index from that of the dispersed particles is added. The difference in the refractive index between the dispersed particles and the solution added with the solvent is made larger than 0.05 and the light penetration rate from the light source 3 through the measured sample liquid (suspension) is made less than 50%. If the difference of refractive index between the dispersed particle and the solution is below 0.05, reduction of the penetration light is not expected and therefore, exact measurement of particle distribution by centrifugal deposition is not possible. By controlling the suspension 2 like this, exact measurement of particle distribution becomes possible even for a sample liquid with small, absorption and large light penetration rate. For the solvent, methyl- ethyl-keton, piligin, chloroform, cyclohexan, etc., are preferably used. And this solvent is desirablly added for 5 to 50vol% in 100vol% suspension.

IPC: F02D41/06
Filed: 1999-01-18
Abstract: PROBLEM TO BE SOLVED: To restrain large vibrations of a driving system during operating am accelerator pedal without lowering a quick-response property of torque of a driving shaft according to the accelerator pedal, in a vehicle in which an air-fuel ratio changes. SOLUTION: This control apparatus compensates a delay in engine torque caused by a change in air-fuel ratio of an engine, by converting an accelerator opening detection value θa to an engine torque instruction value Te to execute advancing compensation on the engine torque instruction value Te depending on the change in the air-fuel ratio. Next, an engine torque instruction value Te' obtained by the advancing compensation is processed by a phase compensator (an inverse filter) obtained by mathematical models of own vehicle and a target vehicle, and then an engine torque instruction value Te" obtained by the inverse filter processing is converted to a throttle valve opening instruction value θt-com. A throttle actuator is driven and controlled to match a throttle valve opening detection value θt with the throttle valve opening instruction value θt-com.  Accordingly, even if the air-fuel ratio of the engine changes, large vibrations of a driving system during operating an accelerator pedal can be restrained without lowering a quick-response property of torque of a driving shaft according to the accelerator pedal.

IPC: F02D41/16
Filed: 1988-01-19
Abstract: PURPOSE:To improve fuel consumption by setting the desired idling speed higher, as the discharge per rotation of a variable displacement compressor is larger at the time when an engine is in an idling state.

IPC: H02M3/28
Filed: 1998-01-21
Abstract: PROBLEM TO BE SOLVED: To operate a converter with stability, by adding a circuit which absorbs variation in the characteristics of circuit elements according to relation between oscillation frequency and current resonance frequency. SOLUTION: In a current feedback self-exciting converter, a voltage is fed back from the additional winding of an output transformer 7 to a drive current transformer 4 through a voltage feedback resistor 6. According to the resistance value of the voltage feedback resistor 6, its feedback factor is adjusted to determine the oscillation frequency of a converter. The relation to current resonance frequency determined according to the capacitance of a capacitor 5 series- connected with the middle point between a pair of transistors 3 and the leakage inductance of the output transformer 7 is maintained so that the oscillation frequency is smaller than the resonance frequency. As a result, small-sized, efficient 'zgro current switching' is achieved through inexpensive measures.
