Title: Shutdown device for dust collector
Inventor: GOTO KAZUYA
IPC: E21B21/00
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To avoid the closing of a cutting conveying passage by arranging a moisture sensor on the inlet side of the cutting conveying passage for a dust collector collecting the cutting of a drilling machine and stopping the operation of the dust collector by the detecting value of moisture. SOLUTION: Cutting discharged to the outside of a pit by blow air generated by drilling is conveyed to a pre-cleaner 13 through a transport pipe 15 form a suction cap 12, and coarse cutting is collected. Fine cutting is collected by a dust collector 14. A moisture sensor S is disposed at a place in the vicinity of the suction cap 12, and a decision section 20 is installed into a control panel 19 on a truck 2. The moisture sensor S detects the moisture of cutting, and transmits a detecting value to the decision section 20. The detecting value is compared with beforehand stored data in the decision 20, and whether or not suction stoppage is required is judged.  Since a stop signal is transmitted at the time of much moisture content and a fan 17 for the dust collector 11 is stopped, trouble, in which cutting adheres on a side wall in the cutting conveying passage and the passage is closed, is avoided.

Title: Output controller for generator
Inventor: SATO OSAMU
IPC: H02P9/00
Filed: 1991-03-13
Abstract: PURPOSE:To sustain operation of generator at maximum allowable output by operating generator output so that the temperature will be within an allowable range, with reference temperature rise data at temperature limit parts, at the time of trouble in cooling system and then controlling the generator output control system based on the operation results. CONSTITUTION:A generator 1 is provided with four hydrogen gas coolers 2. Upon missing of one hydrogen gas cooler, a computor 3 executes an operation based on detected values S1-S4 of generator temperature and delivers a generator output lowering command S5. If the generator output is not lowered, temperature S1 of stator winding exceeds an upper limit. Consequently, generator output is lowered so that the temperature of stator winding lowers below the upper limit. Since the generator output lowering command S5 is determined based on the measured value S1 of stator winding temperature, maximum allowable output can be produced from the generator.

Title: Carrier wave regenerating circuit
Inventor: SASAKI SUSUMU
IPC: H04L27/227
Filed: 1981-04-02
Abstract: PURPOSE:To simplify the circuit constitution in the poststage, by subjecting an input PSK signal to frequency conversion with the output of a voltage control oscillator and multiplying the signal by (n), in the carrier wave regenerating circuit of a PSK demodulating circuit. CONSTITUTION:A carrier frequency omegai of an input P<n>-phase PSK signal is inputted to a frequency converting circuit 6 and is converted to a frequency omegai- omega0 by an output frequency omega0 of a voltage control oscillator 5, and this frequency Wi-W0 is multiplied in a multiplier 1 by (n) to become a frequency nomegai-nomega0, and this frequency is inputted to a BPF2. The center frequency of the BPF2 is nomegai-nomega0, and the phase difference between input and output signals of the BPF2 is detected by a phase detector 4, and the oscillator 5 is controlled by this detection signal. The output of the BPF2 is divided to 1/n by a frequency divider 3, and the frequency becomes omegai-omega0. The output of the frequency divider 3 is inputted to a frequency converter 8 and subjected to the frequency conversion by the output frequency omega0 of the oscillator 5 to output a frequency omegai. Thus, since the frequency after the frequency multiplication is lowered, the circuit constitution in the poststage is simplified.

Filed: 1982-03-29
Abstract: PURPOSE:To allow other memory banks even if one or more memory banks are in busy state under one transfer command, by connecting transfer control circuits which control the execution of transfer commands to respective memory banks. CONSTITUTION:Under a transfer command from a processor, information is transferred to every memory bank independently. In this case, plural memory banks B0-B7 are provided with transfer control circuits C0-C7 which control the information transfer of plural words. Each transfer control circuit operates independently for every memory bank and sends a transfer request to the connected memory bank on the basis of the transfer command supplied from the processor. Consequently, even when one or more memory banks are in busy state under one transfer command, other memory banks perform transfer processing.
