Title: Multirepeater
Inventor: TSUDA HIROHIKO
IPC: G06F13/36
Filed: 1992-05-22
Abstract: PURPOSE:To give no limitation to the number of connection substrates by deciding the signal transmitting direction based on the data transferring direction for a bus repeater including a buffer which receives the address or the data set on a bus and outputs them after amplification. CONSTITUTION:A multirepeater consists of the bus repeaters BR1-BR3 provided for each largest number of pieces N of connection substrates in an ordinary bus system and a control circuit 10. Then repeaters BR1-BR3 have the bidirectional buffers which receive the addresses and the data set on the buses and then amplify and output them and the circuits which decide the signal transmitting directions respectively built-in. A control circuit 10 secures the coincidence of the signal transmitting directions, i.e., the output directions of those repeaters BR1-BR3 between a request substrate and an answer substrate with the direction of data flow. Thus the multirepeater can eliminate the limitation given to the number of substrates owing to the load kept constant for the bus interface set at the output side.

After the growth, the internal pipe 6, the susceptor 4, and the substrate 3 are moved to a receiver chamber 7 with a magnet rod 13, and a gate valve 14 is closed. After that, the internal pipe 6 is separated from the susceptor 4 with a hydraulic magnet cylinder 8 to move the susceptor and substrate to a substrate replacement chamber 9. On the other hand, the internal pipe 6 is further moved to an internal pipe replacement chamber 11 to be isolated from the susceptor receiver chamber 7 with a gate valve 15. After that, an internal exchange opening 12 is opened to replace it with a new one.

Abstract: PURPOSE:To facilitate the adjustment of output by an arrangement in which when the second control switch that sequentially changes the set temperature within a predetermined range is operated under the condition where the test operation mode is selected, the load control is performed by sequentially selecting the output from among the predetermined multistages regardless of the temperature detection by the temperature detection element. CONSTITUTION:When the first control switch 14 is operated, numerical value E1 stored in PP+1 address is loaded to registor S0. When the second control switch 16 is turned on and off one time under such condition, the address of memory A0 assumes PP+2, and the value in the registor S0 becomes E2. The drive pulse having the cycle of E2XTt and width of Tt is outputted from the output terminal T to the solenoid pump 20. Since the cycle of the drive pulse outputted from the output terminal T is repeatedly changed in stages like E1XTt, E2XTt, E8XTt, E1XTt every time on-off operation of the second control switch 16 takes place under the test operation mode, which is totally independent from the room temperature detection action of the thermistor 18, a suitable amount of kerosene for respective stages is supplied by the solenoid pump 20.

Title: Radiation detector
Inventor: TANAKA MITSUHIRO
IPC: G01T1/164
Filed: 1982-07-28
Abstract: PURPOSE:To elevate the enumeration rate characteristic with reduced time required for processing unnecessary signals by setting a trigger level to be slightly lower than the lower limit of a window being set. CONSTITUTION:A window setting device 24 outputs energy level, window width or the like corresponding to setting according to nuclide. With the application of the set output, a trigger level generation circuit 27 computes the lower limit of the window level and determines a trigger level reference value slightly lower than the value to be applied to a comparator 25 to which a detection radiation energy is to be applied through an adition circuit 21. A required trigger signal varying according to the set window is outputted from the comparator 25 to control the start of operation. This prevents the unwanted start of operation according to scattered energy or the like thereby elevating the enumeration rate characteristic with a reduction in time wasted for unnecessary signal processing.
