Title: Start load reducing device of vacuum device using flow control valve
Inventor: ISHIMARU HAJIME
IPC: F04C25/02
Filed: 1990-05-02
Abstract: PURPOSE:To carry out the load reduction at the starting stably by furnishing a flow control valve having a valve body, which is driven by bellows to be driven by the inner-outer pressure difference, in a pipe leading from a vacuum vessel to a rotary pump for exhaustion of the fluid in the vacuum vessel. CONSTITUTION:Before a rotary pump is started, the pressure inside and outside bellows 5 as well as the pressure in a vacuum vessel shall be approx. atmospheric, wherein the bellows 5 are put eccentric to the right by a spring 9, and a valve body 10 is in full closed condition. When this rotary pump is started, the fluid on the line situated on the side nearer the pump than the valve body 10 is first sucked to cause sink of the intra-pipe pressure on the vacuum vessel side and the fluid pressure in the bellows 5. When the force due to the pressure difference between inside and outside of the bellows 5 is enlarged by the resilience of the spring 9, the bellows 5 are contracted against the force of the spring 9, and the valve body 10 is opened through a rod 7 and a con. rod 14. This increases the rate of flow to be sucked toward the pump, and inside of the vacuum vessel the fluid will be sucked until the specified degree of vacuum is attained.

Filed: 1986-05-20
Abstract: PURPOSE:To generate pulses in n-phase formed by accurate by and equally dividing into n-part without any hindrance even if the repetitive period is dissident by always dividing digitally one period of an input signal into (n)-part. CONSTITUTION:A 3-phase clock generator 1 being an n-phase pulse generator converts a clock signal into 3-phase clock signals CK1-CK3 synchronously with a signal fed to an input terminal, the signals CK1-CK3 are counted by counters 2a-2c and the count is latched digitally in latch circuits 3a-3c. The counters 2a-2c and the circuit 3a-3c are reset by the input signal and an output of the circuits 4a-4c is inputted to latch circuits 4a-4c. Further, the output data of the circuits 4a-4c is read as a preset value by using the counters 5a-5c to count the original clock by the number of read values. In counting the clock signal, 3-phase pulses phiR-phiB are outputted to control an analog switch thereby outputting a color signal.

Title: Error detecting system for information processor
Inventor: MIYANO YOSHINOBU
IPC: G06F11/22
Filed: 1986-05-19
Abstract: PURPOSE:To detect the troubles occurring in a system operation mode and also to recognize normal operating period by applying periodically the interruptions to an information processor to carry out a test for check of the presence/absence of an error and at the same time writing a series of time points. CONSTITUTION:An interruption generating means 1 gives the interruption signals periodically to a working information processor via a timer. In this interruption mode a job state store means 2 saves the states of the mobs under execution to a table 3. A test instruction executing means 4 extracts a test instruction out of the block in the table 3 that is indicated by a pointer and executes it. A test result checking means 5 compares the test result with a correct answer in the table 3 and produces an alarm to show detection of an error when no coincidence is obtained from said comparison. While a pointer replacement means 6 replaces such a pointer that shows the store block of the next test instruction when the coincidence is obtained from said comparison. These means 4-6 repeat their operations until a prescribed number of items are attained. A time point writing means 8 writes the time needed for extraction of instructions through comparison of them in a column of 'time point 2' of the table 3 and then the time point when the pointer is replaced to the first instruction store block from the final one in a column of 'time point 1'.
