Filed: 1982-03-05
Abstract: PURPOSE:To attain free exchange in the unit of one channel, by providing time division switches synchronized with each earth station so that satellite lines are used as if they were transmission lines in one exchange. CONSTITUTION:Lines 6 on the earth are connected to time division switches 8, and the time division multiplex signal of the switches 8 is transmitted from a transmitter 9 on the earth station to a satellite reception circuit 11 of a satellite 7. The outgoing side of the circuit 11 of the satellite 7 is connected to the incoming side of a satellite spatial split switch 12, and the outgoing side of the switch 12 is connected to the input side of a satellite transmission circuit 13. Electromagnetic waves transmitted from the satellite 7 are received at a receiver 14 of the earth station, and the reception signal is shared to the lines 6 at a time division switch 15. Through the constitution, each earth station has the time division switch memory of the same content and a spatial split switch memory synchronized with the time division switch memory. Thus, the line exchange is made possible easily by changing the content of the time division switch memory of each earth station and of the spatial split switch memory of the satellite.

Title: Scroll compressor
Inventor: ARATA TETSUYA
IPC: F04C29/02
Filed: 1984-02-29
Abstract: PURPOSE:To secure the oil feeding pressure over a limit oil feeding pressure by installing a valve apparatus for cutting-off the communication to a suction passage into the suction passage of a compressor and reducing the pressure ratio by the valve apparatus when the pressure ratio between the discharge pressure and the suction pressure lowers under a certain value, as in low pressure ratio operation, etc. CONSTITUTION:When the pressure ratio between a discharge pressure and a suction pressure reduces lower than a certain value in case of low pressure ratio operation or frost removing operation, the spool 32 of a valve apparatus 30 installed between the suction chamber 13 and the suction pipe 12 of a compression mechanism shifts to the vacant trunk side 34 of a valve case 31. The opening area of a suction hole 32c for the ports 36 and 37 reduces through the shift of the spool 32. In other words, a suction passage is throttled, and pressure ratio increases. Therefore, when the pressure ratio comes close to a set pressure ratio, the pressure ratio can be kept at a set pressure ratio or more by the operation of the valve apparatus 30. Therefore, the supplied-oil pressure is kept at a limit oil feeding pressure or more, and a necessary amount of oil is stably supplied onto each bearing, and the breakage trouble of the bearing can be eliminated.

Title: Electron gun for camera tube
Inventor: ISHIYAMA KUNIO
IPC: H01J29/48
Filed: 1984-02-29
Abstract: PURPOSE:To enable a small bean spot diameter to be obtained and prevent any image shift which might be caused by the thermal deformation of a beam disk from occurring by maximizing the diameter of an electron-beam-restricting hole in the thickness direction of a beam disk electrode at the center of the hole. CONSTITUTION:A hole which has small inlet and outlet and the diameter of which is maximized at its center, is formed in a considerably thick beam disk (c). The electron-beam-controlling hole is formed, for example, by forming a hole with relatively large homogeneous diameter in a relatively thick plate (C) and then squashing the periphery of the hole by pressing both surfaces of the plate (C) in such a manner as to decrease its thickness as it becomes distant from the center of the hole. As the result, areas of the plate (C) around the inlet and the outlet of the hole protrude toward the center of the hole in canopy-like form and therefore the diameters of the inlet and the outlet of the hole are reduced. Therefore, even when irregularly reflected electrons occur inside the electron gun, they are caught in the hole without being discharged outside. Accordingly, image signals with high resolution and high S/N ratio can be obtained.

Title: Image forming device provided with self-diagnostic restoration system
Inventor: UMEDA YASUSHI
IPC: G03G15/00
Filed: 1991-03-01
Abstract: PURPOSE:To more rapidly and more accurately specify the cause of a fault, to prevent useless restoration from being executed and to perform effective self-restration by specifying the cause of the fault by considering the occurring degree of a fault phenomenon while dealing with a fuzzy qualitative value obtained by considering a deterioration amount read out from a storage means. CONSTITUTION:Since the fuzzy qualitative value of a parameter changed according to the deterioration amount of every previously set timing of diagnosing the fault and the occurring degree of the fault phenomenon caused by the deterioration amount are stored, the qualitative value and the occurring degree are read out in each diagnosing timing. Meanwhile, the condition data detected by sensors 1a, 1b and 1c is made to be the fuzzy qualitative value and the presence or absence of the fault is decided according to the value. When the fault is found, as a result, it is diagnosed by setting the parameter value changed according to the deterioration amount as an initial value, and the cause of the fault is identified. Whether the identified cause of the fault can be restored or not is discriminated, and only when it can be restored, corresponding actuators 6a, 6b and 6c are actuated, and the fault is restored.

Filed: 1989-02-17
Abstract: PURPOSE: To prevent a staple forming track from being clogged with additional staples by allowing the once arrangement of only one staple from a staple stack inside the staple forming track while using a holding means. CONSTITUTION: When moving a driver 18 from an anvil forming surface 20 to a non-contact position, a flexible tab 30 moves to a staple forming track 14 once more. The flexible tab 30 is positioned again just under a convergent point between a skin staple stack 12 and the staple forming track 14. Therefore, the driver 18 passes mover an opening at the skin staple stack 12. Based on this movement of the driver 18, the spring means of the skin staple stack 12 forcedly moves a new staple 16 to the staple forming track 14. Since the flexible tab 30 exists at such a position, only one staple 16 is positioned on the staple forming track 14. Thus, the staple is accurately and effectively driven without the clogging of staples inside the staple forming track 14.
