IPC: G06F3/0354
Filed: 1990-01-26
Abstract: PURPOSE:To use both of a mouse and a tablet with high operability by providing a lattice pattern for optical mouse on the tablet. CONSTITUTION:A lattice pattern 3 for optical mouse is printed on the coordinate input face of tablet 1 to constitute the tablet 1 as a coordinate input device using an electronic pen or a pointing device using a mouse 4. That is, the plate (input operation face) of the mouse (optical pointing device) 4 and the tablet (the coordinate input face of the coordinate input device) are constituted as one body. Thus, the tablet is shared between respective input faces, and the required area is reduced to reduce the space of the installation place, and their operability is improved.

Title: Direct current restoration circuit
Inventor: SHIZUTANI OSAMU
IPC: H04N5/16
Filed: 1983-01-31
Abstract: PURPOSE:To eliminate signal distortion near a vertical synchronizing signal and to prevent variation in DC restoration level due to an input signal by utilizing the switching operation of a transistor (TR) when the DC component of a video signal is restored. CONSTITUTION:The video signal impressed to an input terminal 16 is applied to the base of a TR17. The emitter terminal of the TR17 is connected to a constant current power source 25 through a capacitor 18 and also connected to the emitter of the 2nd TR19 for clamping. The capacitor 18 blocks unnecessary low frequency components. The TR19 has the base voltage held constant by the bias circuit consisting of resistance 20 and 21 and a capacitor 22, and its connector is connected to the base of a TR24. Those TRs 19 and 24 restores the DC component of the input video signal into a bias voltage V1.

Title: Gutter
Inventor: YAMAMOTO KUNIO
IPC: E04D13/072
Filed: 1988-01-25
Abstract: PURPOSE:To prevent the occurrence of breakage, by a method wherein a title gutter comprises a gutter main body formed in a semicircle or a box-shape in cross section and an eaves securing part expanded downward from a position in the vicinity of the one edge of the gutter main body to form a resilient deforming part, and release from a snow load causes restoration of the gutter to its original position. CONSTITUTION:A gutter comprises a gutter main body 1 formed in a semicircle or a box-shape in cross section and an eaves securing part 2 expanded downward from a position in the vicinity of the one edge 11 of the main body 1 to form a resilient deforming part 21. The gutter is formed integrally by a material, e.g. polycarbonate, having abundant resilient restoring force, or formed separably by the material to form an integral one-piece. When a snow load is exerted, through deformation of the deforming part 21, the main body 1 is lowered, snow on a roof surface with which the main body 1 is covered is naturally dropped, and the deforming part is restored to its original position by means of the restoring force of the deforming part 21. This constitution enables prevention of the occurrence of breakage.

Title: Holding insulator
Inventor: TAKAHASHI HIDEOMI
IPC: H01B17/56
Filed: 1993-02-02
Abstract: PURPOSE:To obtain a holding insulator with a small size and a very good insulating property, by composing the holding insulator in the continued surface of a smooth curved surface in which the surfaces from two electrodes separating a specific distance are extended along the equipotential surface, and the curvatures are made reverse near the middle part between both electrodes. CONSTITUTION:A holding insulator 4 is composed of five curved surfaces of curved surfaces C0 and C1 along the equipotential surface around the first electrode 1, curved surfaces C2 and Cn along the equipotential surface around the second electrode 2, and a curved surface Cl for connection having a curvature reverse from these curved surfaces. As a result, the electric field is made vertical on the surface of the insulator at any place near the electrodes, and even though a corona is generated, it is not developed. Since the electric field is in a guitar shape as the whole, although it faces the connecting direction in the curved surface Cl, the corona is never developed further even though it is generated, because it is put in the area where the electric field is vertical rapidly. And, since the equipotential surface is converted in the curved surfaces C0 and Cn and the electric field is relatively small at the rear side of the opposing part, the electric field in the connecting direction can be permitted.

Title: Solar system for generating steam
Inventor: TANAKA TADAYOSHI
IPC: F24S90/00
Filed: 1987-01-27
Abstract: PURPOSE:To reduce the installation space and cost for equipment and installations by providing a first heat exchanger in which heat is exchanged between hot thermal medium heated by collected heat and transported feed water as well as a second heat exchanger which generates steam for processing by heating the feed water with the operating medium. CONSTITUTION:Thermal medium 15 heated to the set temperature by collecting heat in a solar collector 1 exchanges heat with feed water 16 in a heat exchanger 2 where the feed water 16 is heated by the thermal medium 15. As the quantity of heat that can be collected by the solar collector 1 exceeds the set value when the sunshine is abundant, only the set amount regulated by a control valve CV3 is introduced into a heat exchanger 12, and the excessive hot feed water 16 passes through a control valve 4 to be stored in a storage tank 3. The feed water 16 now regulated to the set temperature and set flow rate becomes saturated gas by receiving heat of waste heat source 14 in a heat exchanger 9, which is then compressed in a compressor 10 and exchanges heat with operating medium 17 in the heat exchanger 12. Consequently, the feed water 16 becomes usable steam at still higher temperature and pressure and is supplied to the process.

Title: Optical disk device
Inventor: ENSHIYUU HISASHI
IPC: G11B7/0045
Filed: 1993-02-02
Abstract: PURPOSE:To accurately record information from immediately after the light output of a semiconductor laser at a recording time is corrected and ended according to a nonfocusing amount between the recording layer of an optical disk and a light spot. CONSTITUTION:The reflected light quantity from the recording layer of the optical disk is detected by a photodetector 65, and a focus error signal FE is generated by an ALU 66. The signal FE is made an absolute value by an absolute value circuit 67 to become the absolute value amount FE2 of the nonfocusing amount. In a nonfocusing state, a first prescribed reference voltage value VREC1 is corrected to be high according to the absolute value amount FE2 of the nonfocusing amount by a recording reference voltage setting circuit 68. The signal MOD1 inputted to a time measuring circuit 1 is changed from 'HIGH' to 'LOW' at the same time when the first prescribed reference voltage value VREC1 is corrected and ended by the recording reference voltage setting circuit 68. The time is measured before a prescribed time arrives by the time measuring circuit 1 according to the change, and a second reference voltage value VREC2 lower than the first prescribed reference voltage value VREC1 is set as the VREC.

Title: Steering apparatus for rear wheels of car
Inventor: NAKAMURA KENJI
IPC: B62D7/15
Filed: 1984-01-31
Abstract: PURPOSE:To reduce the turning circle of a car in low-speed traveling by steering rear wheels in the opposite direction to the steering direction of front wheels only when a steering torque increases over a prescribed value. CONSTITUTION:When a steering torque becomes a prescribed value or more and the difference of internal pressure between in the oil chambers 49a and 49b of a power cylinder 19 becomes a prescribed value or more, the difference between the forces which act onto the pistons 45 and 46 of an actuator 31 for steering rear wheels becomes larger than the set load of a coil spring 42. Then, the pistons 45 and 46 or a steering rod 32 shifts in a certain direction by the amount corresponding to the internal-pressure difference between the oil chambers 37 and 38. Therefore, rear wheels 34a and 34b are steered rightward or leftward by the amount corresponding to the shift amount, and the turning circle of car is reduced markedly.
