Filed: 1993-11-18
Abstract: PURPOSE:To provide a transient voltage waveform with almost no lag time between the poles of a circuit breaker to be tested by inserting a lag time compensating circuit between a simulation circuit simulating a short line and the circuit breaker to be tested. CONSTITUTION:A current-source current i1 shown in an AC circuit breaker standard is supplied from a current source 2 to a circuit breaker 1 to be tested.

Title: Electric field emission type electron gun
Inventor: MATSUMOTO KAZUHIDE
IPC: H01J29/48
Filed: 1987-11-18
Abstract: PURPOSE:To realize a high vacuum in an electron gun chamber within a short period of time by generating discharge by controlling the voltage power source while introducing an inert gas required for glow discharge into the electron gun chamber. CONSTITUTION:An electron gun chamber is exhausted with a vacuum pump and is further heated to perform ordinary degassing treatment. When a certain degree of vacuum is reached during this treatment, an inert gas for generating glow discharge is introduced into the electron gun chamber and, under this condition, an appropriate voltage is applied between oxide-coated cathodes 2 and anodes 3, 4 to generate glow discharge. The energy of the glow discharge easily removes the gas adhering to the surface of an electron gun constituting member and accelerates the gas removal treatment out of the electron gun chamber. Thus, the high vacuum in the electron gun chamber can be reached in a short period of time.

Title: Transmission control system for satellite communication earth station
Inventor: TSUBOIKE MITSUYOSHI
IPC: H04B7/155
Filed: 1995-11-09
Abstract: PROBLEM TO BE SOLVED: To attain simultaneous transmission of transmission signals with plural satellite communication base stations causing crosstalk by continuing the transmission of the transmission signals till prescribed transmission is finished even when a reception signal is detected during the transmission of the transmission signal of its own station. SOLUTION: When a reception signal S17 is detected in a transmission channel of its own station, transmission of a transmission signal S8 is stopped and even when the reception signal S17 is detected during transmission of the transmission signal S8 of its own station, the transmission of the transmission signal S8 is continued automatically till prescribed transmission is finished. Thus, in the satellite communication system where plural satellite communication base stations use a same communication satellite 101 and a transmission channel in common, simultaneous transmission of transmission signals by plural satellite communication earth stations causing crosstalk is prevented.  In the SNG(Satellite News Gathering) system or the like especially, artificial operation mistake in transmission control is almost prevented and since the equipment configuration is simple, the installation investment is reduced.

Filed: 1988-11-17
Abstract: PURPOSE:To facilitate the control of a bank register by storing the bank information showing the banks used by plural tasks working in time division into a control table and then setting the bank information stored in the control table at the bank register when each task is working. CONSTITUTION:The values of banks which are used by plural tasks (a) - (n) working in time division are stored in a control table 12. These bank values stored in the table 12 are set at a bank register 5 under the control of a monitor part 11 and every time the tasks (a) - (n) are switched. Therefore the tasks (a) - (n) are not required to care the setting timing of the value of the register 5. Thus it is possible to avoid the confusion of the setting timing and value of the register 5 even though those tasks work at one time in a multi-task mode. Then the control of the register 5 is extremely simplified.

Title: Measurement for gas concentration
Inventor: USUI TOSHIO
IPC: G01N27/416
Filed: 1985-12-24
Abstract: PURPOSE:To measure the concentration of water in a gas to be measured, by applying a voltage to an oxide sensor using a solid electrolyte to determine a difference between a threshold current value and a threshold current value of a dry gas at a first and second flat sections. CONSTITUTION:An oxygen sensor has a hollow capsule with a fine gas passage port opened to the open air capped on a solid electrolyte with an electrode formed on both sides and a threshold current characteristic is utilized as generated by a gas diffusion resistance of the gas passage port. As a voltage applied of the sensor rises, first, a first flat section 12 appears due to the existence of oxygen. Then, a second flat section 13 does because of addition of water. On the other hand, in the case of atmosphere previously cleared of water, a single-stage broad section 15 appears by a dry oxygen portion. Water concentration is determined previously with respect to the difference DELTAIL1D of threshold current value between the flat section 15 and the flat section 12 or the difference DELTAIL2D of threshold current value between the flat section 13 and the flat section 15. Thus, water concentration in a gas to be measured can be measured from the current value DELTAIL1D or DELTAIL2D.
