Title: Power output device
Inventor: TAGA YOSHIAKI
IPC: B60L50/16
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To prevent overcharging of a battery by the generated power when a vehicle is started on an uphill or when the vehicle is running at low speed. SOLUTION: The energy from motors 30, 40 operated by an engine 50 at the efficient operating point is converted into the energy expressed by the product of the number of revolution of a drive shaft 22 by the torque. When a vehicle is started on an uphill or the vehicle is running at low speed where a large torque is required, the engine 50 is operated at the operation point of high energy where the torque is large and efficient, and the large power is regenerated in excess over the consumed energy, and a battery 94 is charged by the large power. The charging by the large power is estimated by the run condition or the geographical information, and the residual capacity of the battery 94 is reduced in advance. As a result, the battery 94 can be prevented from being damaged by overcharging.

Title: Digital-analogue converting circuit
Inventor: TAKEGAWA TOUJIROU
IPC: H03M1/80
Filed: 1979-07-31
Abstract: PURPOSE:To constitute a D/A converting circuit, by connecting many current control circuits consisting of IGFETs in parallel. CONSTITUTION:Double and quadruple mutual conductances are given to IGFET E14 and E15 respectively on a basis of IGFETE13 as a reference transistor. When input terminals I1 and I4 are low-level and input terminals I2 and I3 are high-level, IGFETE16, E19 and E21 are conductive, and E17, E18 and E20 are nonconductive, and therefore, the gate potential of E13 becomes equal to the potential of node 12. At this time, a current flowed from output terminal 13 to E12 operating in the saturation region is denoted as (i). Next, when input terminals I1 and I3 are high-level and input terminals I2 and I4 are low-level, the gate potential of E14 becomes equal to the potential of node 12, and the current flowed from the output terminal becomes i/2 becuase E14 has the double mutual condactance of E13. Similarly, the current flowed to the output terminal can be changed to i/n by changing combinations of input levels of input terminals I1, I2 and I3.

Title: Overload protecting device of inverter device
Inventor: SAITOU NORIYOSHI
IPC: H02M7/48
Filed: 1983-06-03
Abstract: PURPOSE:To prevent the saturation of a transformer by limiting the width of a gate pulse to be applied to an inverter in the half cycle when an overcurrent is detected and setting the gate pulse of th next half cycle to the same shape as the previous pulse. CONSTITUTION:The output of an oscillator 16 is applied though a waveform shaper 17 to one input terminal of a comparator 21. The AC output voltage of an inverter 4 detected by a detecting transformer 18 is applied to one input terminal of a comparator 20 through a rectifier 18, and compared with the output of a DC current detector 15. The output of the comparator 20 is applied to the other input terminal. A gate pulse of the output of the comparator 21 is applied through a pulse width limiter 22 to a pulse amplifier 23. The output of the limiter 22 becomes narrow in the pulse width when an overcurrent is generated. The amplifier 23 amplifies the gate pulse output of the limiter 22 and applies it to the inverter 4.

Filed: 1985-05-07
Abstract: PURPOSE:To search a victim of distress from a long distance, by providing a propulsive rocket which launches a transponder into the sky and a helium-gas balloon which expands in the sky and dropping and floating a battery onto and on the sea. CONSTITUTION:A transponder is launched into the sky by means of a propulsive rocket. Since helium gas is blown into a balloon 3 from a helium-gas cylinder 2, the balloon 3 floats in the sky. The buoyancy of the balloon 3 is set a little stronger than the weight of this transponder system except a battery 7 and cable 6. Since the transmission/reception antenna 4 of this transponder system can be floated at a position higher than the sea level in the sky under this condition, the transponder can be discovered from a long distance by means of a searching radar. The battery 7 is floated on the sea by means of the cable 6.

Title: Method and device for ultrasonic thickness measurement
Inventor: IIDA KAZUHIRO
IPC: G01B17/08
Filed: 1989-04-18
Abstract: PURPOSE:To securely recognize even the waveform of a fine-level bottom surface by setting the recognition range of the bottom surface waveform based upon the peak position of a surface waveform. CONSTITUTION:The variation range of the distance of water as a delay material due to the shake of an ultrasonic wave sensor which is delayed behind the sent pulse of an ultrasonic wave by a time corresponding to the water distance and the unevenness of the surface of a body to be measured is set previously as a surface recognition range 20. Then the surface wavform 14 is read within the range 20 and when the waveform 14 is recognized, the amplitude level of the waveform 14 and the peak position of the time are measured to set the recognition range of the bottom waveform 15 according to the peak position of the waveform 14. Consequently, the bottom surface recognition range 21 is set finely excluding the range of the ringing, etc., of the waveform 14, and the waveform of the fine-level bottom surface can be recognized. Further, the half of the time interval between the peak values of the waveforms 14 and 15 is multiplied by a sound speed value to calculate the thickness of the body to be measured. Further, when the waveform 15 can not be recognized, only time information on the peak value of the waveform 14 is employed and the degree of variation of the surface shape of the body to be measured is measured from the difference from the peak value of the waveform 14 at another place.
