Filed: 1989-09-14
Abstract: PURPOSE:To reduce the occurrence of charging sound generated when a pulsating current is impressed to a contact charging member without losing uniform electrification property by specifying the range of the frequency of an oscillating voltage. CONSTITUTION:The contact electrifier is set at an anechoic chamber, and the value of an AC frequency (f) is varied as maintaining an inter-peak voltage over two times the electrification start voltage at the core bar 1a of a charging roller from an external power source 3.

Title: Earth leakage breaker with overvolatge protection function
Inventor: FURUMOTO TETSUO
IPC: H02H3/33
Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To prevent malfunction for surge or noise impressed through superimposing to a power supply voltage, by dividing the power supply voltage into leakage detecting circuit, connecting a divided voltage to a secondary coil of a zero-phase current transformer via a zener diode, and than grounding the other second coil via a capacitor. SOLUTION: When an overvoltage is impressed across the power supply terminals 101, the same overvoltage is also impressed cross A-C so that the potential B rises proportionally. When the potential B exceeds the preset zener level, the zener diode 303 becomes conductive and a current flows into one end D of a secondary coil of a zero-phase current transformer 203. When a current flows to D, a leakage detecting section 2 performs the same operation as that of the case when leakage current higher than the constant level is detected and causes a thyristor 201 to operate, thereby protecting a load device from an overvoltage by releasing the contacts of a relay 102. Here, when an irregular overvoltage is impressed, a current limiting resistor 304 limits the current flowing to D to a level lower than the constant value.

Title: Pto control device for vehicle equipped with automatic transmission
Inventor: OKUBO TAIJI
IPC: B60K25/06
Filed: 1995-08-24
Abstract: PROBLEM TO BE SOLVED: To prevent unintended sudden transmission of power to a mounted device by connecting a switching means which is closed only when a shift lever is in a parking or neutral position with a PTO relay coil. SOLUTION: A switching means 18 does not cause operation of a PTO relay 10 even at the operation of a PTO operating switch 11 unless a shift lever is in P or N position. Even if the PTO operating switch 11 is pressed by mistake while the shift lever is in positions other than P and N and the engine is at idle, no current flows through a PTO relay coil 10-1. Thereafter, even if the shift lever is moved to P or N position and the switch 9-1 or 9-3 of an inhibitor switch 9 is turned on, no current flows through an electromagnetic clutch relay coil 12-1. This is because a PTO relay contact 10-2 is in an off position. Therefore an electromagnetic clutch 15 does not operate.
