Title: Electron gun for electron tube
Inventor: MURAYAMA YOICHI
IPC: H01J23/06
Filed: 1985-02-05
Abstract: PURPOSE:To heighten dielectric strength, by providing a heater electrode inside the outer end of an electrically-insulating cylinder provided between an anode and an electrode for a heater and a cathode so as to serve as a vacuum enclosure, and by providing an electrically-insulating thin tube between the exterior of the cylinder and the vicinity of the heater electrode located in the cylinder. CONSTITUTION:A heater electrode 7 and an electrode 5 for a heater and a cathode are provided inside the outer end of an electric insulator 4. An electrically-insulating tube 12 is provided. The length of a Wehnelt cylinder can be reduced to diminish the temperature difference between the cylinder and the electrode 5 and the rise in the temperature of the inner end of the cylinder to suppress vacuum discharge. A volume from which gas is evacuated in a gas evacuation process can be also reduced to shorten the time which it takes to perform the process. When an electron gun is dipped in insulating oil, the electrically-insulating tube 12 made of Teflon or the like acts to remove air out of the gun to wet the electrode 5, an electric insulator 6 and the heater electrode 7 with the insulating oil so as to transfer heat out well. The cooling property and dielectric strength of the electron gun are thus enhanced.

Title: Connector for connection of printed board
Inventor: MORI SHUNGO
IPC: H05K7/14
Filed: 1992-01-10
Abstract: PURPOSE:To prevent noises from affecting a bus signal line when a printed board is inserted by a method wherein the communication of bus signals is permitted between a back board and the printed board only when a receptacle connected with a plug-in signal line is fitted in a plug. CONSTITUTION:A bus signal control circuit allows bus signals to be transmitted between a back board 1 and a printed board 6 only when a receptacle 13d connected with a plug-in signal line 12 is fitted in a plug 14d. Therefore, bus signals are not transmitted between the back board 1 and the printed board 6 only when a receptacle 13c connected to a bus signal line 3 is fitted in a plug 14c, but bus signals are made to start being transmitted between the back board 1 and the printed board 6 when the receptacle 13d connected to the plug-in signal line 12 is fitted into the plug 14d. Therefore, noises generated when the back board 1 and the printed board 5 are connected together are prevented from affecting the signal line 3.

Title: Surface acoustic wave filter, branching filter and mobile radio equipment
Inventor: WATANABE KAZUSHI
IPC: H04W88/02
Filed: 1994-02-18
Abstract: PURPOSE:To attain miniaturization and light weight by using part of a frequency band causing an inductive impedance for a pass band of the filter. CONSTITUTION:A surface acoustic wave resonator 4 and an inductive element pattern 9 are connected in series, one terminal connects to ground and a surface acoustic wave resonator 6 and a wire 10-3 used for the inductive element pattern are connected in series and one terminal connects to ground. Since the resonators 2-6 in use are arranged in this order from an input terminal, the length of the wire used for connecting the resonators 5 is reduced and then deterioration in a pass band insert loss attending a shift of the resonance frequency of the resonators 5 is reduced. Since part of the frequency band where the impedance is inductive is used for the pass band of the filter, the two surface acoustic wave resonators whose one-side terminal connects to ground are inductive for the pass band and the other side terminals of them are connected by a capacitive element to obtain a high pass filter in terms of an equivalent circuit. Thus, the surface acoustic wave filter in which the insertion loss for the pass band is small and the attenuation for the black band is high is formed in this way. A small branching filter easily realized and a subminiatured mobile radio equipment is formed.

Title: System for compressing and developing initial value
Inventor: GOTO ATSUSHI
IPC: G06F9/45
Filed: 1988-01-30
Abstract: PURPOSE:To prevent performance from being lowered at the time of compiler and link processings and to prevent the size of an object module from being increased by referring initial value information when the initial value in the object module is developed on a load module and repeatedly developing the initial value so that the size of an area, in which the initial value is embedded, can be filled up. CONSTITUTION:When object modules OM1-OMn are generated and it is necessary to store the repetition of initial value in the object modules OM1-OMn, not the number of repetition of the initial value but the size of the area, in which the initial value is embedded, is set to the initial value control information to correspond to the storing initial value. Then, in a link processing 22, the initial value is repeatedly developed so the size can be filled up. Accordingly, in a compiler 1, it is not necessary to separate the couple of an initial value image and the initial value control information to one initial value and in the link processing 22, the number of the processing initial value control information is not increased. Thus, the performance is prevented from being lowered at the time of the compiler and link processings and the size of the object module can be prevented from being increased.

Title: Fuel controller for engine
Inventor: HAYAKI TAKASHI
IPC: F02D41/12
Filed: 1989-01-31
Abstract: PURPOSE:To expand a fuel-cut range by resetting a fuel supply when a throttle valve is once operated in the more opening direction than the specified valve opening through fuel-cut rotational frequency, while maintaining the fuel supply unless it becomes more than the fuel-cut rotational frequency. CONSTITUTION:When valve opening of a throttle valve being detected by a valve opening detecting means is less than the specified value as well as when it is detected by a speed detecting means and engine speed is more than fuel-cut rotational frequency, a fuel-cut means controls a fuel supply means, performing a fuel cut, and when it becomes less than reset rotational frequency, a first resetting means resets the fuel supply. When the valve opening of the throttle valve is once operated in the more opening direction than the specified valve opening after entering the speed range through fuel-cut rotational frequency at the range between the fuel-cut rotational frequency and the resetting rotational frequency, a second resetting means rests the fuel supply, while this fuel supply resetting is maintains unless it becomes more than the fuel-cut rotational frequency. Thus the fuel-cut range can be expanded without any torque shock.
