Title: Portable computer
Inventor: IWAI KIYOSHI
IPC: G06F1/00
Filed: 1989-03-07
Abstract: PURPOSE:To save required data before expiration of the life of a battery by reading a warning message from a memory to display it on a display device at the time of detecting that the voltage of the battery is reduced to a reference value or lower. CONSTITUTION:A supply voltage reduction detecting circuit 2 always monitors the voltage of a battery 1; and when this voltage is reduced to a reference value slightly lower than the voltage, with which the operation of a computer is impossible, or lower, this circuit outputs a voltage reduction detection signal. This signal is inputted to a CPU 4 through an OR circuit 3 and is directly inputted to an I/O port 5. The message to warn a computer user of reduction of the supply voltage to the reference value or lower is preliminarily stored in a main memory 7, and the CPU 4 performs interrupt handling to read out and display the warning message from the memory 7 to a display device 10 at the time of input of the voltage reduction detection signal. Thus, the computer user finds expiration of the life of the battery and stops the executing processing to perform a required processing.

IPC: H02M7/48
Filed: 1991-03-19
Abstract: PURPOSE:To eliminate short circuit of arm and to suppress error voltage by providing each arm element in a bridge circuit with a PWM signal and an OFF signal. CONSTITUTION:A current flowing through a current sense semiconductor switch(IGBT) in an upper arm element in response to a PWM signal having no time lag is detected through a current detecting circuit 6 and the polarity thereof is then decided through a polarity deciding circuit 5. It is then fed to a switching operation circuit 10 and a photocoupler 1 is connected through a switching circuit 2 with a driving circuit thus turning the current sense IGBT 8 ON/OFF. At the same time, a switching circuit 21 is connected through the switching operation circuit 10 with an OFF signal generating circuit 91 and a driving circuit 41 thus sustaining the IGBT 81 in OFF state. Consequently, short circuit of arm does not occur even if the IGBT 8 in the upper arm turns ON/OFF with no time lag. According to the invention, error voltage due to time lag can be suppressed even when detection of polarity is difficult.

Title: Emergency stopping device for lpg charging device
Inventor: AINE RIYOUICHI
IPC: F17C6/00
Filed: 1979-04-28
Abstract: PURPOSE:To prevent explosion of LPG by separating the liquid feeding hose from the pipe after shutting off the power source to the whole device by stopping feeding LPG when an abnormal tensile force is applied on the liquid feeding hose. CONSTITUTION:When abnormal tensile force acts upon the liquid feeding hose 5 from below, the second spring in the fitting member body 23 contracts and the balancer body 19 is shifted downward. At the same time, the dog 29 leaves the limit switch 27 which is switched to close the solenoid valve 3 to shut off power to the whole device. By this constitution, not only that residual LPG in the feeding hose 5 would not leak but also there is no fear for explosion even if the liquid feeding hose is separated from the pipe as the power to the whole device is shut off.

Title: Polarization curve measuring instrument
Inventor: YAMAZAKI KIYOSHI
IPC: G01N27/416
Filed: 1985-03-19
Abstract: PURPOSE:To make it possible to check whether the instrument itself is normal or not by measuring a polarization curve by using an actual load prior to the start of the measurement of the polarization curve. CONSTITUTION:Resistors 13, 14 are simulation loads and are the resistors to simulate the actual load consisting of a counter electrode 3, a reference electrode 2 and a test specimen 1. Gates G1-G9 are the gates for changing over the flow of signals. The gates G1, G4, G8 are held closed and the gates G2, G3 are held open and the signals flow to the actual load side during the ordinary measurement. The signals are passed to the simulation load side by opening the gate G1 and closing the gates G2-G4, G8 in the stage of self-diagnosis. Since the simulation load is constituted of the simple resistors 7 and 8, the polarization curve is a simple straight light. Whether the instrument itself is normal or not can be therefore tested by using the simulation load of the known characteristic and measuring the polarization curve. Since the resistors 13, 14 are the simple resistors, the stable testing with good reproducibility with the decreased deterioration with lapse of time, temp., etc. is made possible.

Abstract: PURPOSE:To enable detection of acceleration a low acceleration and low frequency areas by spreading and supporting a laminate body junctioned integral with a diaphragm and an inorganic piezoelectric element in a vibration hole while a circular hole is formed at the center thereof. CONSTITUTION:A detector section 1 is so arranged that a diaphragm 2, a thin film shaped inorganic piezoelectric element 3 and a laminate body R are supported being spread in a round vibration hole 6a at a fixed section 6 while a circular hole 5 with an inner diameter thereof about 15-80% of that of the hole 6a is formed at the center thereof concentrically with the hole 6a and the hole 6a and the element 3 are integrated in a direct junction. Then, when the laminate body R is vibrated in the hole 6a by an external force, a detection of vibration with a higher sensitivity and a higher output is accomplished with the action of the hole 5 formed at the center thereof. As the holes 6a and 5 are arranged concentrically, a balanced vibration is generated to reduce variations in characteristics and moreover, as the diaphragm 2 and the element 3 junctioned directly in an integral manner achieves a higher impact resistance while assuring a stable output and frequency characteristics at low acceleration and low frequency areas.

IPC: F02F1/00
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To provide an oil groove machining method for an engine cylinder bore capable of forming an oil groove in the arbitrary part of the engine cylinder bore through an extremely simple method, reducing an equipment cost and improving workability. SOLUTION: A small diameter part 5 is formed at an engine cylinder bore 4 part needing formation of an oil groove during a cutting work. By a cutting tool and a cutting tool 6 for inner grounding exchanged with a tool, the small diameter 5 is grinding-finished in the same inside diameter size as that of other part. Thereafter, inner surface finishing is effected through honing work. Since a groove deeper than that of other part is formed in a part equivalent to the small diameter part 5 during a grinding finishing work, a part of a deep groove remains as the oil groove.
