Title: Commutation failure detector of chopper circuit
Inventor: AWANO TOSHIAKI
IPC: H02M3/135
Filed: 1983-01-31
Abstract: PURPOSE:To enhance the reliability without erroneously outputting a detection signal by forming a current detection timing pulse in double systems and obtaining the detecting timing pulse under AND condition. CONSTITUTION:When a chopper circuit CH fails in commutation at a regenerative brake time with an armature A and a field winding F, a counter CT outputs a detection allowance pulse (f). When a current I flows to the chopper, and the commutation failure is detected by the AND condition of the current I and the output C of the DC current transformer DCCT. In this case, a current detection timing pulse (g) is produced from a one shot circuit OS on the basis of the OFF pulse signal (b), the final current detection timing pulse (d) is obtained through a logic product circuit AND2 of the pulse (g) and the current detection timing pulse (f) from the counter CT, thereby accurately detecting the commutation failure. A switch LB is turned OFF by this detection, thereby interrupting the circuit.

Title: Two-stage compression type refrigerating apparatus
Inventor: TAKAHASHI TOSHIMASA
IPC: F25B1/10
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To control the temperature of the discharged gas with excellent responsiveness by interposing a parallel circuit of a capillary tube and a liquid injection valve to an inlet side of an intercooler, and controlling the liquid injection valve by the temperature of the discharged gas of a higher stage side compressor. SOLUTION: A capillary tube 11 is set to the resistance so as to secure the minimum liquid refrigerant flow rate required in an intercooler 6 and required to keep the degree of superheat of the higher stage side sucked gas to an appropriate value. A liquid injection valve 12 controls the temperature of the higher stage side discharged gas, and a temperature sensing cylinder 12a is installed on a higher stage side discharge pipe 23. When the temperature of the higher stage side discharged gas D is below the allowable value, the liquid injection valve 12 is closed.  When the temperature of the higher stage side discharged gas is not less than the allowable value, the liquid injection valve 12 is operated, and controls the opening to increase the flow rate of the refrigerant flowing into the intercooler 6 to drop the temperature of the higher stage side discharged gas below the allowable value.

Title: Counting system
Inventor: TAKEUCHI EIICHI
IPC: G01P3/489
Filed: 1978-02-13
Abstract: PURPOSE: To count accurate number of revolutions including that at the non-steady rotating by forecasting the rotating periods of a rotator based on the pulses corresponding to the 1/n frequency division of the rotating periods of the rotator in performing counting.  
     CONSTITUTION: The pulses of a pulse generator 8 corresponding to the revolutions of a capstan shaft 4a, etc. cause a one-shot circuit 13 to generate a pulse at each 1/2 frequency division of the rotating period of the shaft 4a and this clears the counter 14 which counts the clock of frequency ϕ/2 of a clock generator 15. These pulses are then counted in a counter 21 via OR gate 20. The count contents of this counter 14 are subtracted from the clock of the period ϕ via register 17 and the borrow output outputted by a subtractor 19 becomes the forecast signal including the period at which the non-steady revolutions change linearly to steadily revolutions, by which the gate 20 is controlled. On the other hand, the output pulse of the circuit 13 causes the count value of the counter 21 to which the addition signal is applied via one-bit counter 24 to be corrected of the count by the initial output pulse of the circuit 13 absent of the forecast signal, thus the accurate counting of the number of revolutions including that at the non-steady rotating time is accomplished.

Title: Structure for preventing dew condensation in enclosed distribution panel
Inventor: SUZUKI NOBUO
IPC: H02B1/28
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To make enable prevention of dew condensation at desired places inside an enclosed distribution panel, without providing a space heater of large capacity. SOLUTION: This structure prevents dew condensation, not by raising temperature in an entire area inside an enclosed distribution panel, but by increasing the surface temperature of a molded insulator 4 supporting a charged part. To do this, a current is caused to flow from a screen electrode power supply 2 to a screen electrode 5, built in the molded insulator 4 via screen electrode switches 3. In this instance, the output voltage of the screen electrode power supply 2 is adjusted or the output current is suppressed, so that the current can be minimal for requirements. In addition, the housing of the enclosed distribution panel is constituted of metal plates using a heat insulating material, and only the molded insulator 4 among inside devices are heated by similar means.

Filed: 1985-02-01
Abstract: PURPOSE:To decrease the stress on film substrates during cutting by forming the film substrates of a multi-worked substrate in such a manner that the stretching direction of the film substrates is perpendicular to the end face on the terminal part side. CONSTITUTION:Cut outs 2 are preliminarily provided to the parts corresponding to the terminal parts of the film substrate on the side where the terminal parts of the multi-worked substrate 1 are not formed. The substrate 1 is cut at the cutting parts 3 at the end face of the terminal parts, i.e., in the direction perpendicular to the parts 2 by using, for example, an air cylinder type cutting machine using a blade edge. The stress onto the film substrates is decreased if cutting parts 3 for cutting simultaneously two sheets of the upper and lower substrates in the stretching direction of the film substrates of the multi-worked substrate are formed in the direction perpendicular to the end face on the terminal part side, i.e., in parallel 4 with the stretching direction. The exfoliation of the seal and defective size are thus prevented and the yield is prevented.
