Abstract: PURPOSE:To inspect pulse width and a phase of a pulse signal of a digital circuit in a short period by constituting the circuit of first and second exclusive OR (Ex-OR) gates, NOT AND (NAND) gate, an FF, a display circuit, etc. CONSTITUTION:A standard pulse signal of a digital circuit and a signal which has delayed this standard pulse signal by a first delaying circuit 3 are applied to the first Ex-OR gate 2, and by its output signal, an allowable value of a pulse signal is generated. Also, the standard pulse signal which has been delayed by the second delaying circuit 4, and a pulse signal to be inspected which has been delayed by the third delaying circuit 7 are applied to the second Ex-OR gate 5, and by this output signal, a detecting pulse signal is generated. Moreover, the output signal (allowable value) of the gate 2 is brought to signal inversion, and the output signal (detecting pulse signal) of the gate 5 is inputted to a NAND gate 8 through an AND gate. Subsequently, by an LED of a display circuit 10 for showing an output state of a reset/set FF 9 which is triggered by an output signal of the NAND gate 8 and whose output is inverted, whether a circuit to be inspected is good or bad is displayed.

Title: Controller for motor
Inventor: KATAGIRI TAKASHI
IPC: H02P29/00
Filed: 1991-10-29
Abstract: PURPOSE:To prevent the run away of a motor and other abnormal operations by constituting it such that a control means stops the motor when a detection means detects that the speed command signal has gone out of the amplitude of a triangular wave. CONSTITUTION:In case that the command signal at the time of the pulse width- duration modulation signal 9 is 'H' gets over the amplitude of the rectangular wave and is fixed to 'H', a second timer 34 is preset and counts down each time the pulse-duration modulation signal is reversed to 'H' or 'L'. And, while the pulse-duration modulation signal 9 is reversed alternately to 'H' and 'L', it is preset when the count value reaches the value according to the duty. But, when the pulse-duration modulation signal 9 is 'H', if the command signal 7 gets over the amplitude of the triangle wave 8 and the pulse-duration modulation signal 9 is set to 'H', the second timer 34 continues the counting, so the count value becomes zero, and outputs an alarm signal as a detection signal, so a microprocessor 3 stops the motor 5.

Title: Abnormality detecting device of diesel engine start auxiliary device
Inventor: MORISADA KAZUTOSHI
IPC: G01M15/04
Filed: 1993-12-10
Abstract: PURPOSE:To provide an abnormality detecting device of diesel engine start auxiliary device which can utilize the effect of a glow plug at the maximum level. CONSTITUTION:An abnormality detecting device of diesel engine start auxiliary device decides that it is abnormal when the voltage levels of a power feeding signal 1a to a glow plug, relay driving circuits 2 and 3, and the glow plug, generate a disagreement with each other. A time measuring circuit 12 decides that it is abnormal when the time to generate the above disagreement continues for a specific time. As a result, a case to restore to the normal condition after disagreement is generated instantly is not decided as abnormal. A pulse measuring circuit 12c counts the number of the above disagreement, and when the number exceeds a specific value, it decides as an abnormal condition. In other words, when the instant disagreements are generated repeatedly, it is decided to be abnormal. When it is decided to be abnormal, the power feed to the glow plug is stopped through the relay circuits 2 and 3.

Title: Delayed-open type solenoid valve
Inventor: KUNO HIROSHI
IPC: F25B41/04
Filed: 1989-12-01
Abstract: PURPOSE:To restrain and ease the abrupt inflow of refrigerant without using a special controller by a method wherein a pilot type refrigerant on-off valve is provided on a pipe upstream an expander in a refrigerating circuit and its main valve is brought in action after the refrigerant pressure on the outlet side is increased to some extent. CONSTITUTION:Where flow resistances of a leakage flow path 2a, bypass flow path 1f and pressure equalizing pipe 2b and A, B and C, those flow paths are designed so that a relationship of A > B > C is established, and where the refrigerant flow resistance of an expansion valve is D, D >= B. When the difference between pressures in a back pressure chamber 1e and a low pressure chamber 4c decreases gradually and becomes less than the compression force of a valve spring 6, a differential pressure valve 5 closes the pressure equalizing pipe 2b. As a result, the pressure in the back pressure chamber 1e sharply drops because the refrigerant is fed into the back pressure chamber 1e only from the leakage flow path 2a and the refrigerant rapidly flows out through the bypass flow path 1f. Therefore, a main valve disc 2 is pushed up by the refrigerant pressure in a valve chamber 1a against the compression force of the valve spring 6, and the refrigerant is directly supplied from an upstream flow path 1b to a downstream flow path 1d.
