Title: Memory protecting circuit
Inventor: MURAKAMI ISAO
IPC: G06F1/00
Filed: 1985-06-11
Abstract: PURPOSE:To evade abnormal writing to a memory which is caused in a switching mode of a secondary power supply, by applying surely the signal to a memory protecting circuit to secure a writing action to the memory in said switching mode. CONSTITUTION:A timer 4 is set to satisfy t2>t1, where t1 is equal to the time needed for generation of a set signal 120 after the rise of a voltage signal 110 and t2 is equal to the time needed for completion of the counting action of the timer 4 after the rise of the signal 110. Therefore the output 13a of an FF3 is equal to 0 as long as the signal 120 is not produced by the time t2. While an AND gate 5 is set under an output inhibiting state and a writing pulse signal 130 is inhibited. Thus no memory writing signal 15 is produced. The output of the timer 4 is set at 1 with the output 13b of the FF3 changed to 1 from 0 after the time t2. Thus the output of an AND gate 6 is equal to 1. Then a single pulse generator 7 produces a reset signal 17. This signal 17 has the same function as the reset signal obtained when a primary power supply has arise. Thus a program is executed again at a specific address.

Title: Mobile course guiding system with offset warning mechanism
Inventor: HATANO ITARU
IPC: G01C21/28
Filed: 1981-08-14
Abstract: PURPOSE:To prevent the accumulation of errors caused by the drift of a direction sensor, by delivering the warning message of the direction sensor every time when a car travels continuously for a certain period of time. CONSTITUTION:The 1st counter 32 is reset when a pulse counter 13 works to transmit the sample clock signal and starts counting again. Accordingly the output of the counter 32 is never turned on while a car is travelling. The counter 32 has an overflow and transmit the reset signal to the 2nd counter 33 when the car stops and no output arrives from the counter 13 for a certain period of time. When the car travels continuously for a certain time, the counter 33 has an overflow and transmits the message output signal to a message output processing part 34. Then the counter 33 sends a warning message onto a travelling locus display 10 to perform the offset of a direction sensor. As a result, the accumulation of errors caused by the frift of the direction sensor can be prevented.

Title: Valve system for internal combustion engine
Inventor: KIMURA SATOSHI
IPC: F02B27/06
Filed: 1994-06-09
Abstract: PURPOSE:To relieve sudden starting of exhaust blow down so as to reduce exhaust pulsation noise by providing a cam by which the maximum value of acceleration in the normal direction on the valve opening side of an exhaust valve is reduced below the maximum value of acceleration in the normal direction on the valve closing side. CONSTITUTION:The maximum acceleration A1 in the normal direction on the valve opening side is set to 60-90% of the maximum acceleration A2 in the normal direction on the valve closing side, and a position in which acceleration reaches the maximum acceleration A1 on the valve opening side is set to an approximately 20 degree previous to the bottom dead center. As a cam is set so that the acceleration is gradually increased to the maximum acceleration A1, a speed on the valve opening side of an exhaust valve is increased slower than a conventional one. In each of the number of revolutions from 3000 to 6000, starting of exhaust blow down can be changed more gradually than a conventional one. In this way, exhaust pulsation noise can be remarkably reduced in the vicinity of 2000 revolutions and 3500 revolutions or more, and especially, higher components in the exhaust pulsation noise can be greatly reduced.

Title: Fuel injector
Inventor: NAKAGAWA TOYOAKI
IPC: F02D41/00
Filed: 1983-07-14
Abstract: PURPOSE:To prevent excessively high electric power from being applied to the solenoid of a solenoid valve in the defectiveness of a control system or in the like, by cutting off electric power and sending an action stop instruction to a control circuit when the detected value of the electric power applied to the solenoid has been higher than a set value for a prescribed time. CONSTITUTION:Fuses 70 are connected as electric power detection and cutoff means in series between a control circuit 69 and the solenoids 53 of solenoid valves 42 so that the fuse is molten off when a prescribed quantity of electric power is applied for more than a prescribed time. When the fuse 70 is molten off, the voltage across the solenoid 53 becomes zero, the level of the output signal of an OR circuit 75 becomes low, and an exclusive OR circuit 77 sends out a high-level signal to the control circuit 69. As a result, the circuit 69 stops supplying driving electric power to the solenoid valve 42, to suspend a control function or give warning or the like. The solenoid 53 is thus protected from excessively high electric power even if a control system develops a trouble or acts wrongly. Therefore, the solenoid 53 is prevented from being overheated, burned out, or the like.

The layer may be a laminate type photoconductive layer consisting of a charge generating layer and a charge transferring layer. The planar heating element may be cylindrical or platelike. When the sensitive body is kept at about 40 deg.C by supplying electric current to the heating element, a clear image is formed at all times. The relative humidity of the sensitive body is reduced especially at high humidity by increasing the temp. to prevent reduction in the potential and to maintain high image density. The sensitive body has superior durability.
