Patent JP-H045935-A (JP)
Title: Vacuum cleaner
Inventor: BABA MASAHIRO
IPC: A47L9/00
Filed: 1990-04-23
Abstract: PURPOSE:To prevent air from leaking in a contact part of a safety device and to stabilize the performance by installing a seal member formed by a soft material on the seal surface of an inner cover. CONSTITUTION:To the seal surface of an inner cover 17, a seal member 21 formed by high density urethane is fixed, and brought into contact with an edge part 17a of an air inflow port of a cover. Since an inner cover 18 is pressed toward a cover 16 through a spring holder 20 by a spring 19, the seal member 21 is pressed against the edge part 17a of the air inflow port, but since the seal member 21 is formed by high density urethane, adhesion of the seal member 21 and the edge part 17a of the air inflow port is satisfactory, and its seal becomes complete. As a result, in a standard use state, it does not occur that air flows in from the seal face. Also, even if there is variance of spring force in the spring 19, since the seal of the seal member 21 and the edge part 17a of the air inflow port is complete, there is no malfunctioning of the cleaner due to air leakage.

Title: Electric automobile
IPC: B60L11/18
Filed: 1992-03-31
Abstract: PURPOSE:To suppress lowering of charge recovery performance of a driving power supply due to overdischarge. CONSTITUTION:A power supply capacity detecting means detects capacity of a driving power supply. In other words, a voltage detecting circuit 31 detects voltage of a DC power supply 14 and determines the capacity of the driving power supply 14 based on a relationship between the capacity and the voltage. If the capacity thus detected is lower than 180V, maximum torque level Tmax is limited. In other words, even if an operator delivers a request torque command T1 higher than the maximum torque value Tmax, output torque value Tout is limited below Tmax. Consequently, power consumption required for driving a vehicle through a DC brushless motor 13 is suppressed and thereby the DC power supply 14 is prevented from entering into overdischarge state.

Title: Gas processing method of j-shaped or u-shaped groove
Inventor: YOSHIKAWA MITSUAKI
IPC: B23K7/00
Filed: 1978-08-31
Abstract: PURPOSE: To greatly alleviate the cutting precision allowed at the time of cutting, by applying gas gouging of linear semi-elliptical form to the position forming part of bottom curve of the J-(U-)shaped groove at the junction end, when processing the J-(U-)shaped groove using gas gouging and gas cutting at the same time.  
     CONSTITUTION: A gouging face 3 having a linear part parallel to the junction end is pierced in semi-elliptical form in the junction end of a base metal 1 by gas gouging torch. The base metal 1 is then cut in an oblique direction toward the linear by means of gas cutting torch 4. As a result, the cuttable range is enlarged by the linear portion (shaded part), and the cutting precision allowed at the time of cutting may be greately alleviated by the corresponding portion. Besides, when the cutting line 5 is placed on the linear part of the gouging face, dross does not flow directly into the gouging face 3. In addition, the groove may be machined easily under the similar gas cutting conditions as in the conventional V-groove preparation method.

IPC: B01D19/00
Filed: 1995-04-28
Abstract: PURPOSE: To miniaturize a deaerator by a method wherein steam, introduced from a steam inlet pipe, is injected by a steam nozzle into the opening end direction of a mixing pipe with an ultrasonic wave to increase the blowing speed of the steam into feed water. CONSTITUTION: Steam, introduced from a steam inlet pipe 8, is injected from a steam nozzle 3 into feed water, which has flowed into a mixing pipe 2 through a feed water inlet port 1 and is provided with the subcool degree or 20 deg.C, with the speed of about 900m/s and is condensed while forming steam cone 9 whereby two-phase flow of feed water, which has become substantially saturated water, and the steam, containing an inert gas, is generated. The two-phase flow flows into an outlet nozzle 4 and flows out of a cyclone type steam separator with a high speed while the steam, containing the inert gas, is separated through a centrifugal separator and is discharged out of an inert vent 7 but the feed water flows out of a feed water outlet port 6. According to this method, a deaerator can be miniaturized.

IPC: G06F13/12
Filed: 1989-04-25
Abstract: PURPOSE:To save the peripheral circuits and to miniaturize a base board by preparing a selection circuit containing a shift register which outputs successively the corresponding selection pulses to plural input signal lines and an output port which transmits a clock train and synchronism instruction equivalent to a single period of the clock train to the shift register. CONSTITUTION:The input signals 1 - n of the digital data are inputted to a selection circuit which contains a shift register 21. A signal A' produced from a signal A is inputted to a clock terminal of the register 21. A signal B' produced from a signal B is inputted to a data-in terminal of the register 21. Then the register 21 produces the selection pulses Q1 - Qn and secures an AND between these pulses and the signals 1 - n. Thus it is possible to attain the input and the identification of signals via two output lines and an input line against the inputs received from many signal lines. Then the peripheral circuits can be saved down to the three lines and the overall size of a base board is also reduced.

Title: Gate signal delay circuit
Inventor: SAKADO YOSHITOMO
IPC: H03K5/135
Filed: 1984-05-24
Abstract: PURPOSE:To obtain an inexpensive gate signal delay circuit which is constituted in a narrow space, by using an up/down counter. CONSTITUTION:While a signal is inputted to a gate signal input terminal 1, an up-counting control terminal S1 goes to the high level, and an up/down counter 10 performs up-counting. If a timing signal is impressed from a terminal 2 on the way of up-counting, an FF8 is set, and a down-counting control terminal S2 goes to the high level, and the up/down counter 10 is set to the holding state. When the input signal in the gate signal input terminal 1 disappears thereafter, the up/ down counter 10 starts down-counting because the up-counting control terminal S1 goes to the low level. When the counted value becomes +1, a decoder 11 transmits the output of logical ''1'' to reset the FF8, and the up/down counter 10 is reset. Thus, the gate signal is reproduced and outputted to an output terminal 9 of the FF8 as a signal which is delayed till application of the timing signal.
