IPC: H01M4/38
Filed: 1996-06-10
Abstract: PROBLEM TO BE SOLVED: To provide a nickel-hydrogen storage battery excellent in high ratio discharge characteristic in which the initial battery internal pressure is reduced by treating a hydrogen storage alloy with acid without drying after it is pulverized in a solution. SOLUTION: In the manufacture of a hydrogen storage alloy electrode using a hydrogen storage alloy as negative electrode material, a method of pulverizing the hydrogen storage alloy in a solution, and then adding an acid solution thereto so that the pH value of the solution is 0.5 or more and 3.0 or less. When the hydrogen storage alloy is treated with acid, a Ni rich layer is formed on the surface to improve the high ratio discharge characteristic. On the other hand, since the hydrogen storage alloy is not dried by pulverizing the hydrogen storage alloy in the solution, and adding the acid solution having a high concentration thereto, the acid treatment can be performed without oxidizing the surface. Therefore, the high ratio discharge characteristic is improved, and the battery internal pressure can be prevented from being raised in the initial charging.

Title: Sensor-level checking system
Inventor: HIGASHIDE TOMOHIRO
IPC: G01D5/347
Filed: 1987-06-15
Abstract: PURPOSE:To perform highly reliable maintenance, by comparing the voltage of a comparing voltage generating circuit and the voltage of a sensor. CONSTITUTION:A voltage V1 from a sensor 1 is compared with a comparing voltage V3 from a comparing-voltage generating circuit 15 in a differential amplifier circuit 9. When the voltage V1 is larger than V3, a voltage from a power source E3 is sent to an input port 11. The fact that a medium is not present in the sensor 1 is recognized with a processor 12. The processor 12 gives instructions to the circuit 15 through an output port 14 on the basis of the instructions of an instructing means 13 so that the voltage V3 is change stepwise. Thus the voltage is sequentially changed from a low voltage value to a high voltage value. Data, which are inputted into the port 11, are monitored. The value of the comparing voltage, which is increased stepwise, and at which the signal of the sensor 1 or 5 that is selected with the port 11 erroneously recognizes the presence of the medium, is checked. The result is stored, e.g. in a memory. Since the value of the voltage of the circuit 15 is increased stepwise by the means 13, the processor 12 can find the allowance of the medium detecting sensitivities of the sensors 1 and 5. In this way, highly reliable maintenance can be carried out efficiently.

Title: Illegal ride check system
Inventor: YAMADA KENICHI
IPC: B42D25/25
Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To prevent illegal rides in regard to the use of a stored fare passenger ticket or a commutation ticket by making each passenger ticket receive and store the passing information on each station, where the train does not stop, that is sent from the passing information transmission means prepared in each vehicle of the train. SOLUTION: When a train arrives at a station F, an F-station passing information signal is produced by a passing information signal generator 3 of a passing information transmission device 100 prepared in each car 90 of the train and transmitted into the car 90 by a transmitter 2 via an antenna 1. Each stored fare passenger ticket receives and stores the passing information signal. In the same way, the passenger ticket stores an E-station passing information signal when the train arrives at a station E. When a passenger passes through an automatic ticket examination machine of a station D, the information showing that the passenger passed through the stations F, E and D is sent to the ticket examination machine from the passenger's ticket.  The ticket examination machine calculates a fare covering the section where the passenger actually passed and sends the fare to the passenger's ticket. The passenger's ticket adjusts the difference of the fare and transmits a normal ride signal to the ticket examination machine if the balance is confirmed.

Title: Switch for gas insulated circuit breaker
Inventor: YAMAGIWA TOKIO
IPC: H01H33/91
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To reduce the used quantity of gaseous sulfur hexafluoride without deteriorating the insulation property and arc-extinguishing performance by providing a conductor section stored in a grounded tank, a stator, a needle contacting to or separated from the stator, an action unit driving the needle, a first block storing an insulating medium, a feed section of the insulating medium, a second block surrounding the needle and the stator, and an exhaust section for the flowing-out insulating medium. SOLUTION: A compressor 13 is installed on the outside of a feed section. When the needle 4 is separated and disconnected from a stator 5 by the open instruction from a control device 60, an action unit 7 is operated to move an action rod 6 to the action unit 7 side. When the needle 4 is moved, the compressed air stored in a first block 32 passes through an opening section 40 and extinguishes the ignition arc between the stator 5 and the contact piece of the needle 4. When the pressure in a second block 31 is increased, a valve 23 is opened to release the pressure into the atmosphere. The mixed gas with sulfur hexafluoride (SF6 ) or nitrogen gas is used for the gas filled in a third block 30, and the used quantity of SF6 gas can be reduced.

Title: Terminal mounting machine and wire harness manufacturing equipment provided with it
Inventor: SUZUKI TOSHIAKI
IPC: H01B13/012
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To accurately feed a hoop and to disengage a terminal while keeping its accurate shape. SOLUTION: A feed pin 146 is fed by inserting and passing the feed pin 146 straight down through an insertion hole (h) provided along the feeding direction of a hoop T and by moving it in the feeding direction. Since the feed pin 146 constrains the hoop T in the feeding direction by being perfectly caught by the hoop T to perfectly prevent the overrun of the hoop T, the hoop T can be stopped at a designated position, the hoop can be accurately cut and a terminal can be accurately disengaged. If a hoop holding pin 151 is inserted straight down into an insertion hole located at a different position from the insertion position of the feed pin 146 in advance of insertion of the feed pin 146, the hoop T can be more accurately fed, accordingly, the hoop T can be accurately cut and the terminal can be accurately disengaged.
