Title: Sucker structure
Inventor: OCHIAI NOBUTOSHI
IPC: B25J15/06
Filed: 1991-10-22
Abstract: PURPOSE:To constantly maintain proper suction force by dividing a lower chamber in a sucker main body into a plurality of suction chambers, by communicating each suction chamber to an upper chamber through a communication hole and an auxiliary hole, and by providing a valve by which the communication hole is closed when the air flow floating from the suction chamber into the upper chamber reaches a predetermined value. CONSTITUTION:When a porous plate 3 is brought into contact with an objective 15 to be sucked to suck the objective 15 by a suction tube 6, a lower chamber 5 is divided into a plurality of suction chambers 9, and since a valve 12 is provided on a communication hole 11 for closing the communication hole 11 when the air flow floating from each suction chamber 9 into an upper chamber 7 reaches a fixed value, even when there is a partial gap between the objective 15 to be sucked and the porous plate, the air flow to be sucked is increased in the suction chamber 9, and the valve 12 is closed. The negative pressure of a vacuum source is prevented from being reduced, and suction force of the other suction chamber 9 can be maintained, and even when there is a crack or uneven part on the objective 15 to be sucked suitable suction force is constantly maintained. Suction of the suction chamber 9 is stopped by an auxiliary hole 13 of small diameter when the communication hole 11 is closed, and loss of suction force is thus prevented.

Abstract: PURPOSE:To efficiently supply electric power to the cursor part of the cordless digitizer which consists of the cursor part and a tablet part and performs electric power supply to the cursor part and the attraction of a form mounted on the tablet part by radio. CONSTITUTION:The pattern of electrodes 3a and 3b is formed on an insulation plate 3, a DC voltage is applied from a DC power source 14 to the formed electrode pattern to attract and hold the form, and an alternating voltage is applied from an AC power source 15 to the same electrodes 3a and 3b through capacitors C1 and C2 to supply the electric power to the cursor part. Consequently, a grid plate for power supply which is conventionally used is omitted, the table part and cursor part can be arranged adjacently to each other, and the gap between them is eliminated, so the electric power can efficiently be supplied. Further, the same effect is obtained even when a winding coil for supplying the electric power by electrostatic coupling and the electrodes for attracting the form electrostatically are constituted on the insulation plate in one body.

Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To enable function setting to a hand set by simply inputting the identification information of call originating side equipment to that hand set in a communications system composed of a base unit and hand set. SOLUTION: The telephone number of equipment on the side of an oppite party inputted by pressing the ten key of a hand set is stored in the first telephone number area of a base unit (S26) and the hand set, which inputs that telephone number, is stored in a registered equipment area (S27). When a call is terminated from the party side equipment of the telephone number stored in the first telephone number area, a ring back tone is sounded only from the equipment (base unit or hand set) stored in the registered equipment area corresponding to that telephone number. Thus, when there is a call terminated from the equipment on the side of the party, only by simply inputting the telephone number of that equipment on the side of the party, setting for sounding the ring back tone only with the hand set used for inputting can be performed.

Title: Engine
Inventor: OTANI NOBORU
IPC: F02B53/00
Filed: 1988-11-29
Abstract: PURPOSE:To obtain a compact and high powered engine with good fuel efficiency by confining a mixed gas in a sealed space with projections and notches of two rollers, igniting and exploding it to give a revolving force to a rotary shaft with the expanding pressure of the burning gas. CONSTITUTION:As the front of a projection 4 passes a suction port 10, the blocking of a compression chamber 8 is done by the contact of the projection 4 and circles of rollers 1, 2, and its hermetical sealing by the contact of the projection 4 and the edge of an ignition/explosion chamber 5. The projection 4 then gains its maximum entrance into the ignition/explosion chamber 5 to achieve the maximum compression of a mixed gas sucked in, and the ignition and explosion take place at that time or immediately before. Although an expanding pressure is evenly applied to the projection 4 and the explosion chamber 5 at that moment, a revolving force is generated as revolution starts with an inertia and a difference is caused in the areas in the front and at the back of the projection 4 receiving the expanding pressure. With further revolution, the pressure on the back of the projection 4 turns out to be a revolving force in its entirety, which pushes out exhaust gas from an exhaust port 11 in the front of the projection 4 and sucks in the mixed gas from a suction port 10 into a suction chamber 9 at the back of the projection 4.
