Title: Dividing device
Inventor: ITO TOSHIO
IPC: F16H27/02
Filed: 1991-05-24
Abstract: PURPOSE:To divide a main spindle through synchronism of a feed amount in the direction of the axis of the main spindle and the rotation angle of the main spindle with each other by rotatably and axially movably arranging an input shaft to a body and locating a on-way clutch in a transmission machine extending from an input shaft to as dividing table. CONSTITUTION:A clutch 18 (19) of an input shaft 4 (5) is engaged with a clutch 11 of a main spindle 3 of a machining center, and the main spindle 3 is rotated through the rigid tap function of the machining center to effect rotation through synchronism of a moving amount in an axial direction and the rotation angle of the main spindle 3 with each other. Since, during forward rotation of the main spindle 3, rotation is not transmitted through operation of a one-way clutch 20 (21), no dividing of a dividing table 47 is carried out. When the main spindle 3 is reversed after a stop, the one-way clutch 20 (21) is operated, the rotation thereof is transmitted, and the dividing table 47 is rotated to effect dividing.

Title: Electric motor vehicle
Inventor: FUKATSU TOSHISHIGE
IPC: H02J7/04
Filed: 1987-06-15
Abstract: PURPOSE:To enable preventing too little current and performing a charge surely by initializing a timing action, when a power supply from a power source side is interrupted and a traveling motor is driven by operation of an operating means during a charge. CONSTITUTION:When a microcomputer 14 judges that a power supply from a power source side is interrupted on the basis of a detection signal from an AC detection circuit 34 during a charge, it causes the timing action of a timer counter 15a to be held as said action is in the existing timing state. When said microcomputer 14 detects in its timing holding state the operation of any of a forward and backward lever 19, an accelerator pedal 23, a lift lever 28, a tilt lever 29, and a reach lever 30, it initializes the timing action of said timer counter 15a. As a result, when a charge is performed after said power supply from the power source side has been interrupted and a traveling motor 6 has been driven by a battery 5 during a charge, the timer counter 15a starts the timing action for charging from its initialized state.

Title: Production of electrophotographic organic photoreceptor
Inventor: HINATA NAOHISA
IPC: G03G5/10
Filed: 1995-06-16
Abstract: PURPOSE: To obtain a photoreceptor with which images having high quality are obtainable even when this photoreceptor is used for an electrophotographic device of a reversal development system by including a stage for rubbing and washing the surfaces of conductive substrates with a polishing agent-contg. plastic brush into a stage for cleaning the surfaces. CONSTITUTION: The stage for rubbing and washing the surfaces of the conductive substrates with the polishing agent-contg. plastic brush is included into the constitution cleaning the surfaces. As a result, the stains of the surfaces are chipped off by the polishing agent and the cleanliness is improved. The occurrence of image defects, such as black spots on white paper parts and white dots and unequal densities on black paper parts is drastically lessened. The material of the brush may be any materials, insofar as such materials have the hardness to the extent of not damaging the surfaces of aluminum base materials and having resistance to an alkaline detergent, etc., for which a polyamide resin is more adequate. Silicon carbide or alunma is adequately used as the polishing material to be incorporated into the brush.  While an alkaline detergent and neutral detergent are adequate as the detergent to be used for the rubbing and washing with the brush, the mere use of water is equally effective.

IPC: G01M15/00
Filed: 1982-08-31
Abstract: PURPOSE:To lower the cost and to enhance the reliability of the titled operation, by employing such an arrangement that the idling operation is detected from the discharge quantity of a hydraulic pump driven by an engine. CONSTITUTION:A hydraulic pump 14 for feeding oil 12 in an oil sump 11 via a hydraulic pressure feed passage 13 is driven by an engine and the discharge quantity of oil 12 is varied with the engine speed. Here, arrangement is such that a required hydraulic pressure is not produced before the engine speed becomes 100rpm-200rpm higher than the idling speed. A manual valve or a change-speed range control valve is communicated with the hydraulic pressure feed passage 13, and a hydraulic pressure control valve 15 functioning as a hydraulic pressure detecting means is disposed at an intermediate portion of the passage 13. Here, since pressure oil is not supplied to an oil passage 32 when the hydraulic pressure control valve 15 is in the idling position as shown in the drawing, gears are shifted to the second-speed position and occurrence of creep is prevented.

Abstract: PURPOSE:To suppress the splashing of condensed water scraped up from a water receiver and to efficiently spray the condensed water to an outdoor side heat exchanger. CONSTITUTION:Blades 8 for scraping up condensed water are disposed at separate positions at the front side of a propeller fan 6 to be rotated coaxially with the fan 6.
