Title: Control device and method for hybrid automobile
Inventor: SUMIYA TOSHIHIRO
IPC: B60L50/16
Filed: 1999-09-08
Abstract: PROBLEM TO BE SOLVED: To reduce an output of an internal combustion engine without deteriorating efficiency of the internal combustion engine. SOLUTION: An operation rate of an accelerator pedal is sensed by a CPU based on a signal sensed by means of an accelerator pedal sensor (S1). Self car speed is sensed based on a vehicular speed signal from a car speed sensor (S2). An output required by an engine is calculated from the accelerator pedal operation rate and the self car speed (S3). It is determined whether the calculated requirement output value is less than a set value or not (S4). When the answer is YES, a changeover valve is changed over according to a changeover control signal from the CPU (S5). Air heated by a radiation means of an inverter is intaken into an intake system through a heating passage.

Title: Relay arrangement
Inventor: KAWAGUCHI KOJI
IPC: H01H50/34
Filed: 1988-10-07
Abstract: PURPOSE:To attempt reduction in working noise generated between contacts at the time of attracting and making a relay contact, and generated between an iron segment and a core, by setting the spring force of a plate spring holding a movable contact and also the attracting force of an electromagnetic coil to always have a balanced point against each other in the course of deforming the plate spring. CONSTITUTION:The arrangement in the title, which includes a movable contact 2 held by a plate spring 1 and spacedly opposed to a stationary contact 3, and an iron segment 11 held by the plate spring 1 and being attracted by the core of an electromagnetic coil 4, has the iron segment 11 attracted by the electromagnetic coil 4 so that both of contacts 2, 3 are mutually contacted and electrified. Both the spring force of this plate spring 1 and the attracting force of the electromagnetic coil 4 are set to always have a balanced point against each other in the course of attracting and deforming the plate spring 1. The attracting force of the electromagnetic coil 4 is gradually increased having the passage of time after being electrified according to its self-inductance. Accordingly, the attraction and deformation of the plate spring 1 may be relaxed having the passage of time with an increase in the attracting force. Thus, the movable contact 2 provided onto the plate spring 1 is connected gently to the stationary contact 3 and at the same time, the iron segment also is contacted gently to the core of the electromagnetic coil 4 so that the working noise of the arrangement may be reduced to such a king of one as having lower volume.

Title: Production of regenerative pump and impeller
Inventor: ITO MOTOYA
IPC: F04D29/18
Filed: 1993-10-12
Abstract: PURPOSE:To improve pump efficiency by improving shape of an impeller and improving both of inflow to vane grooves and outflow from the vane grooves. CONSTITUTION:A lot of vane pieces 39 and bulkheads 41 for dividing each vane groove 40 between respective vane pieces 39 in two are formed on the outer circumference of an impeller 28. The vane pieces 39 are so curved that the root parts of the vane pieces 39 tilt backward in the rotational direction R of the impeller 28 and the tip sides of the vane pieces 39 tilt forward in the rotational direction R. Backward tilting of the root parts of the vane pieces 39 reduces each angle formed between circling flow, which flows from a side face to the vane grooves 40, and the roots parts of the vane pieces 39 so that the circling flow flows smoothly into the vane grooves 40. Moreover, forward tilting of the tip parts of the vane pieces 39 in the rotational direction R provides kinetic energy from the vane pieces 39 to fuel flowing into the vane grooves 40 so efficiently that pump efficiency may be enhanced effectively.

Abstract: PROBLEM TO BE SOLVED: To provide a motion detection method capable of promptly detecting motion and to easily transmit pictures when the motion is detected. SOLUTION: Data SDV based on signals SV from a device 1 are encoded by a block unit in an encoding part 20 and encoded data CS are stored in a memory part 30.

In a control part 31, the difference amount of the DC component data of the memory part 30 to the DC component data of the memory part 32 is calculated for the respective blocks and integrated. It is judged that the motion is generated when an integrated value exceeds a prescribed value and communication data SD are generated based on the data CS of the memory part 30.  The communication data SD are transmitted through an interface and a public communication channel to a prescribed transmission destination as transmission signals SS in a modem part 34.

Title: Assist air controller for internal combustion engine
Inventor: FURUTA KOICHI
IPC: F02M23/12
Filed: 1987-10-08
Abstract: PURPOSE:To achieve both idle control and assist air control efficiently by setting first intervals for increasing flow of a flow control valve and second interval for reducing flow alternately, and setting the first interval synchronously with an interval which includes an interval immediately preceeding the fuel injection interval. CONSTITUTION:In regulation of bypass air through an assist control means 10, first intervals for increasing flow of a flow control valve M7 and second intervals for reducing flow are set alternately, where the first interval is set synchronously with the interval which includes an interval immediately preceeding the fuel injection interval. Since large quantity of bypass air synchronized with the interval which includes an interval immediately preceeding the fuel injection interval is led in an assist air during first interval, atomization of fuel is promoted. Large quantity of bypass air is fed only during a short interval synchronized with fuel injection during the second interval to promote assist function and the quantity of bypass air is controlled during other intervals, and thereby regulation of suction air suitable for idle control can be carried out easily.

The molten composite material is dropped onto the rotor 23 rotating around a horizontal shaft 26 at high speed in the heat-resistant vessel 22, and spattered by the rotation and agitation. Consequently, the formed primary Si crystal is crushed. The spattered semi- molten composite material is received by the vessel 22, and discharged as the massive semi-solid aggregate having a homogeneous microstructure. By this method, a wear-resistant hypereutectic Al-Si alloy composite material having excellent mechanical properties is obtained.

This saw-tooth-wave signal E drives a transistor 6, and corrects the cathode waveform of a cathode ray tube 7 to a signal waveform F. When the amplitude of the inverse of Y signal A is high, the amplitude of the detection signal B is also high. The current of the current source transistor 5 is increased to make the amplitude degree of the differential amplifier high. The amplitude and inclination of the saw-tooth-wave are increased and the correction quantity of the cathode waveform of the cathode ray tube 7 is increased. On the other hand, when the amplitude of the inverse of Y signal A is low, the opposite operation is made and the correction quantity is made small.
