Abstract: PROBLEM TO BE SOLVED: To control acceleration at low sound and large torque by driving a timer actuator so as to obtain such an injection timing as decreasing acceleration sound and at the same time increasing the torque, when an accelerator is operated right after starting a self-sustaining driving continuing to the starting operation. SOLUTION: In starting an engine, when a key switch 13 is turned on, a control part 21 recognizes a cooling water temperature, a fuel temperature, an intake air temperature, a voltage coefficient of a battery 12, etc., and decides a target adjustment quantity rack position in starting control and a target timer rack position in starting control are decided based on respective maps. And a rack actuator 2 and a timer rack actuator 3 are driven by control signals output from a CPU 33 based on the respective rack positions. The pre-starting timer is counted under this starting preparation state and a starter is driven. After starting of the engine and when the engine speed is larger than a stall recognition engine speed, it is moved to a steady operation state based on a position of an accelerator 8.

Title: Method and device for receiving orthogonal modulation wave
Inventor: TANAKA HIRONORI
IPC: H04L27/22
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in a reception characteristic due to an image component of an undesired wave in the receiver that applies quasi-synchronization orthogonal detection to an intermediate frequency signal from an RF section where a frequency step of a frequency synthesizer for intermediate frequency conversion is set to be an integer multiple of a frequency step of a reception channel.

The quasi-synchronization orthogonal signal is given to an A/D converter 8, where the signal is converted into a digital signal and it is fed to a digital frequency shifter section 32.  The digital frequency shifter section 32 uses a frequency converter 9 to shift a frequency to allow an LPF 13 to output a desired wave component so that a desired reception channel is a base band signal, a frequency converter 11 detects a base band component of an undesired wave and applies prescribed arithmetic operation based on both the base band components to calculate an image component of the undesired wave and when the undesired wave is a prescribed level or over, the image component of the undesired wave is subtracted from an output of the LPF 13.

Abstract: PURPOSE:To attain small power consumption and leakage current measurement, by using a constant current circuit or a constant voltage circuit as a power supply of an oscillation circuit and a dynamic frequency division circuit and intermittently interrupting said power supply and the dynamic frequency division circuit. CONSTITUTION:A power supply voltage Vs outputted from a constant current circuit or a constant voltage circuit 4 is applied to dynamic frequency division circuits 2 and 3 via an N channel transistor 7.

Title: Abnormal cylinder detecting device for internal combustion engine
Inventor: OSAWA KOICHI
IPC: G01M15/11
Filed: 1990-04-02
Abstract: PURPOSE:To properly detect an abnormal cylinder by correcting the allowable range according to the load, offsetting the variation portion of the degree of the angular speed variation according to the load, and judging the degree of the angular speed variation, thus eliminating the influence of the load. CONSTITUTION:The angular speed variation generated on an output shaft during the preceding and succeeding explosion processes is detected in each explosion cycle by an angular speed variation detecting means M1. An abnormal cylinder detecting means M2 calculates the degree of the angular speed variation in each cylinder on the basis of the angular speed variation, and the cylinder outside an allowable range is detected as abnormal cylinder. In this detection, an allowable range correcting means M4 corrects the allowable range according to the load of the internal combustion engine which is detected by a load detecting means M3. The allowable range is spread and contracted according to the increase and decrease of the load of the internal combustion engine. Accordingly, the abnormal cylinder detecting means M2 detects the abnormal cylinder through the offset of the variation portion of the angular speed variation due to the load, and the proper detection of the abnormal cylinder which is not influenced by the load can be realized.

Filed: 1979-07-10
Abstract: PURPOSE: To utilize a small pressure of fluid for a motive force to pump up and drain water by forming a forced water curtain or a siphon on the injection line of a nozzle on the discharge side of a jet pump.  
     CONSTITUTION: A water-conduct pipe 2 is circular ring around a center line 7 of a nozzle 1 with a circular section, and connected to a joint 3. A slit 4 is provided to form a water curtain with a curved surface of a cone given by the locus of a right line which connects between the center of the section of the water-conduct pipe 2 and a point on the center line 7 of the nozzle 1 and provides an angle α of about 45 degrees when pressurized water is sent to the joint 3. The pressurized water introduced from the joint 3 is conducted through the water-conduct pipe 2 and the slit 4 to form the water curtain with the curved surface of the cone, which not only intercepts the atmospheric pressure on the discharge side, but also sucks the air on the side of the nozzle 1 and discharges to the discharge side to reduce the air-pressure on the side of the nozzle 1. Since the surrounding pressure is further lowered by the velocity of water jetted out from the nozzle 1, liquid can be pumped up from the end of a hose connected to a section joint 5.

Title: Electric power source for electroluminescence(el) lamp
Inventor: MIKI YUJI
IPC: H05B44/00
Filed: 1990-04-02
Abstract: PURPOSE:To lower the rise of voltage applied to a deteriorated EL lamp by oscillating alternating current with a specific frequency by an astable multivibrator and controlling the oscillation frequency of the astable multivibrator by the alternation of the electrostatic capacity of an EL lamp. CONSTITUTION:Low voltage direct current V1 to be put in is altered into high voltage by a high voltage generating circuit 1 and converted into alternating current by a DC-AC converting circuit 2. An astable multivibrator 3 of the DC-AC converting circuit 2 oscillates rectangular wave with the same frequency as that of the alternating current to be supplied to an EL lamp. The frequency of the astable multivibrator 3 is determined by a frequency specifying device 6 to specify a self-running oscillated frequency and the return from a transformer T2 connected with the EL lamp. Accordingly, the oscillated frequency is not specified only by the electrostatic capacity of the EL lamp and even the EL lamp becomes deteriorated, the voltage applied to the EL lamp does not immediately increase. As a result, the EL lamp is lighted brightly for a long duration and the rise of voltage of alternating current to be supplied to the EL lamp is suppressed and electric consumption is lowered.

CONSTITUTION:An adhesive tape 12 is fed out from a paper roll mounted to a mounting roller 16 and allowed to pass between a feed roller 18 and tape retainer belt 28, then fed out externally by the prescribed dimension through a tape offset guide 32 and outlet 40 to perform feed preparation. If the tape 12 is cut by a cutter 42, a microswitch operates to urge a rotary driving source 26, and the tape 12 is fed by rotation of a mounting roller 20 transmitted with power by the feed roller 18 and a belt 24. When a photosensor 46 and dot mark 44 detect a prescribed rotary distance, the rotary driving source 26 instantaneously stops. In this way, a fixed dimensional tape can be surely fed to rationalize adhesive tape sticking work.
