Title: Emergency information transmitting device
Inventor: IKEDA MASATOSHI
IPC: B60L15/40
Filed: 1995-11-01
Abstract: PROBLEM TO BE SOLVED: To make it possible to perform continuous control comparable to the function of an ATC at a low cost. SOLUTION: An emergency information transmitting device is made up of ground devices, a power receiving device, and an on-vehicle device. The ground device receives inward track circuit current or the condition of indicating the presence or absence of the inward circuit current to turn its output ON when the inward track current exists. Then, after an elapse of a fixed time after the inward track circuit current is shut off, the output turns OFF, and when the inward track circuit current is left shut off, the output turns ON after maximum dropping time has elapsed. Sending current of an outward track circuit is controlled so as to turn ON and OFF by the output of the device. The power receiving device receives track circuit current. When it is detected that the track circuit current is shut off momentarily for specified time interval, the on-vehicle device recognizes that an emergency is generated on the ground.

Abstract: PURPOSE:To reduce the amt. of jitters contained in a reproduced signal from recording pits by forming a protective layer interposed between a recording layer and a reflecting layer with a material having a specified refractive index or above to the wavelength of light for irradiation. CONSTITUTION:A 1st protective layer 2, a recording layer 3, a 2nd protective layer 4 and a reflecting layer 5 are successively formed on one side of a transparent substrate 1 and a UV-curing resin layer 6 for protection is disposed on the surface of the reflecting layer 5 to obtain a phase change type optical disk.

The material of the 2nd protective layer 4 has a refractive index of >=2.4 to the wavelength of light for irradiation. The difference in absorptivity of an amorphous part in the recording layer 3 can be made lower than that of a crystalline part and the difference in absorptivity in the reflecting layer 5 can be made larger than that in the recording layer 3.

Filed: 1992-09-30
Abstract: PURPOSE:To eliminate the disturbance of a screen even when the outside of a virtual screen area is displayed and to form plural screens by providing a non-canister virtual mode for which the outside of a specified area is a transparent area in the formation of images by a computer system using a virtual screen. CONSTITUTION:A mode for which the outside of the specified area is entirely the transparent area on the virtual screen on a memory is prepared and called as the 'non-canister mode'. Then, by providing such non-canister mode, the virutal screen can be constituted of the plural screens such as main and sub screens. In the non-canister mode, the area outside of the virtual screen is the transparent area. For a real screen belonging to the virtual screen in such mode, the area of the real screen outside of the virtual screen becomes transparent (hatched part). Thus, the screen of the area outside of the screen is not disturbed. Also, a screen size can be freely changed and the efficiency of the memory can be enhanced.

Abstract: PURPOSE:To correct a tracking error of a scanning light beam at a high speed by adopting such the constitution that a collimator lens is moved as the scanning light beam is landed onto a prescribed scanning line. CONSTITUTION:A laser beam LA1 radiated from a light source 1 is converted into a collimated light by a collimator lens 2, converged as a scanning beam LA2 via an objective lens 6 to scan an optical recording medium 7. The reflected light LA3 is restored to a scanning position detector 9 via a beam splitter 3. Thus, if the landing position of the beam LA2 is deviated, a scanning position detection output S1 is obtained and a tracking control circuit 10 sends a tracking error signal S2 to a tracking drive section 21 accordingly. The drive section 21 uses the signal S2 to apply the moving control the lens 2 in a direction (a) orthogonal to the optical axis. The size and weight of the lens 2 is made small sufficiently comparing to those of a lens 6 then the lens 2 follows the signal S2 even if its speed change is made larger.

Title: Conveying device for sheet
Inventor: MORI MASAHIRO
IPC: B65H29/22
Filed: 1987-11-11
Abstract: PURPOSE:To greatly reduce projection marks and remaining unevenness and obtain a copy with a high-quality sheet material condition by discontinuously providing projections having a large outside diameter in the circumferential direction on one end portion of each of wider rollers out of pairs of rollers while continuously providing projections having a larger diameter than the former projections on the other end portions. CONSTITUTION:Projections 1a, 2a having larger outside diameters are continuously formed in the circumferential direction while projections 1b, 2b, 3b, and 4b having smaller outside diameters are discontinuously formed in the circumferential direction. When a sheet material 9 passes through discharging rollers 1, 2, curls perpendicular to the advancing direction can be formed by means of the projection 1a and rollers 5, 6 and the projection 2a and rollers 7, 8. On the other hand, the projections 1b-4b kick out the rear end of the sheet material 9 with their discontinuous portions, preventing the sheet material from stopping with its rear end left riding over the rollers 1, 2. At this time, the sheet material 9 on the projections 1b-4b can hardly suffer deformation because of the projections, making it hard to leave projection marks and obtaining a copy with a high-quality sheet material condition.

Abstract: PURPOSE:To make slit width of a cylinder into a constant state at all times by installing a buffering stop means tightly in a desired position on top of the cylinder via a fitting mechanism astride the top of the cylinder and the underside of the buffering stop means. CONSTITUTION:Kinetic energy given by an impact causes mutually reverse reaction to one end and the other end of a connecting part, and this reaction acts on engaging guide means 22 opposedly set up on an almost triangular cylinder outer circumferential surface 352. Consequently, a horizontal component is induced in a ramp 353 on one side, a vertical component on an incline and the horizontal component is induced in a ramp 354 on the other, the vertical component on the incline, respectively. Even if such-like components act thereon, a clearance between the top of a cylinder 35 and the underside of a buffering stop member 10 is in no case produced there and solidly unified as one body owing to a fitting mechanism being made up of fitting one set of a recessed groove 23 and a projection 24 symmetrically to axis set up in a slit 21, so that these horizontal components can be internally offset.
