Title: Address reading method for optical recorder
Inventor: UKITA HIROO
IPC: G11B20/18
Filed: 1981-09-11
Abstract: PURPOSE:To surely access tracks, by using a different error correcting system of address information formatted as pit information in advance from that of data information to be additionally recorded. CONSTITUTION:Reproduced digital information 61 is separated into addresses and data with an address data separating circuit 62. The addresses and the data are respectively error-corrected at error correcting circuits 63, 65. Since the address information produced with pressing through formatting in advance has different error characteristics from that of data information recorded afterward, and since the error correcting system suitable for the respective errors is used, correct detection of the address information can be done and the high- speed accessing to tracks can surely be performed.

Inventor: ANZAI MASAYASU
IPC: G03G15/01
Filed: 1981-09-14
Abstract: PURPOSE:To make the high speed formation of two-color images possible with a simplified optical system by using a recording medium consisting of a conductive substrate, a photoconductive substrate and a transparent insulating layer, and subjecting the same to a specific electrostatic charging treatment then to the 1st developing after exposure of the 1st light image and the 2nd light image followed by the 2nd developing after uniform exposure. CONSTITUTION:The surface of a photoreceptor formed successively with a photoconductive layer 2 and a transparent insulating layer 3 on a conductive substrate 1 is electrostatically charged uniformly to form the electric charge reverse from that of the surface at the boundary of the layer 2 and the layer 3. Said surface is electrostatically charged reverse to decrease or invert the surface charge. After the 1st light image 1E is exposed thereon and the surface of the recording medium is charged uniformly in succession, the 2nd light image 2E is irradiated thereon. The area irradiated with the 2nd light image is reversally developed by using an electrostatically charged toner 4 of the same polarity as that of the 1st latent image and the recording medium is exposed uniformly; thereafter the 1st light image part is developed with the 2nd developer. The two-color images are transferred, whereby two-color images are obtained.

IPC: B41J29/377
Filed: 1995-06-12
Abstract: PURPOSE: To detect a clogging in a suction nozzle and a filter downstream of the former individually by measuring a negative pressure using a single vacuum gauge. CONSTITUTION: A vacuum gauge 15 is arranged in a communicable manner with the upstream and downstream of a filter 3 through a switching means 16, then a reference air inflow path 17 is provided on the upstream side of the filter 3, and a suction nozzle 1 is closed, while the reference air inflow path 17 is opened. Thus a negative pressure in the upstream and the downstream of the filter 3 is sequentially measured by switching the switching means 16 in such a state that air is aspirated from the reference air inflow path 17, so that the clogging of the filter 3 is judged by the difference in the measured negative pressures.  In addition, the negative pressure upstream of the filter 3 in the state that the suction nozzle 1 is closed and the reference air inflow path 17 is opened and in the state that the suction nozzle 1 is opened and the reference air inflow path 17 is closed is sequentially measured. Finally it is interpreted whether the suction nozzle 1 is clogged using the differential pressure reading.

Title: Solid laser ocillator
Inventor: IMAI SHINICHI
IPC: H01S3/04
Filed: 1984-07-12
Abstract: PURPOSE:To uniformize the temperature distribution inside a solid laser element and improve the laser performance, by providing excited light diffusing members for uniformly applying excitation light to the cooling surfaces of a solid laser element. CONSTITUTION:Excitation light rays radiated from excitation light radiation lamps 4, 4 are applied to diffusing plates 5, 5 directly or after they are reflected by excitation light reflecting parts 6, 6, as shown by the one-dot chain line. When passing through the diffusing plates 5, 5, the excitation light is diffused so as to be uniformly applied to excitation cooling surfaces 3, 3 of a solid laser element 2. Accordingly, the excitation light radiated from the lamps 4, 4 can be uniformly applied to the whole of the excitation cooling surfaces 3, 3 of the solid laser element 2. It is therefore possible to uniformize the temperature distribution inside the laser element 2. Thus, it is possible to prevent saturation of the laser beam output due to self-focusing or self-double refraction.

IPC: B22D11/12
Filed: 1986-06-23
Abstract: PURPOSE:To uniformize cast slab temp. and to reduce the cost by arranging a plane combustion burner around the cast slab at the end period of solidifica tion and also using commonly heating of the burner and the diffusion of latent heat in the cast slab. CONSTITUTION:At the end period of solidification in the cast slab 1, the plane combustion burners 2-1-2-3 are arranged and by burning the fuel gas at this internal part, a refractory permeable solid existing therein is heated. Then, radiated heat of the heated solid radiates to each face of cast slab 1, to execute uniform heating. As the heat radiation face by the plane combustion burner is plane, the uniform heat radiation covered on the wide area is possible. Further, the latent heat in non-solidified cast slab part 1 is diffused to the outer face of solidified shell together with heating by the plane combustion burner. Therefore, high temp. in the cast slab 1 is uniformized and the cost is reduced by effective use of the heat.

Abstract: PURPOSE:To inexpensively and efficiently form a thin sheet even if it is a hard-to-work material such as an intermetallic compound by passing plural, parallel, metallic fine wires through a molten metal bath and solidifying molten metal adhered. CONSTITUTION:The molten metal bath 3 is formed in a vessel 1, plural metallic fine wires 4 of the same kind of metal as the molten metal bath are dipped in parallel from the upper part in the molten metal bath 3 in such a state that the fine wires 4 are brought into contact with one another or they are very adjacent to one another and lead out of an opening 2 to the outside of the container 1. The molten metal 30 around parallel metallic fine wires 4 lead out of the opening 2 is solidified by a cooling zone 5 and each metallic fine wire 4 is integrated with the solidified metal 30' to obtain a thin sheet 6. The metallic fine wire 30 is made of fine crystals in property and since the molten metal 30 adhered to the metallic fine wires 4 is small in capacity, it is rapidly cooled by the cooling zone 5 and makes fine crystals. Consequently, the thin sheet 6 obtained is, as a whole, of fine crystals and, as a result, rolling, too, can be carried out comparatively easily.

Title: Communication device for train control
Inventor: SUGAWARA ATSUSHI
IPC: H04B1/707
Filed: 1994-06-03
Abstract: PURPOSE:To carry out train detection being high in antinoise property by providing an on-train information generating means for generating on-train information on the PN marked correlative detection signal of an on-train side PN mark generating means in the case where a signal sent from an on-train side modulating means is in process of detection. CONSTITUTION:Since a rail R is short-circuited by the axle of a train A, the level of a signal sent out from a ground transmission section (a) on the side of final end Y becomes small. The output level of a receiver 10 inputted from the rail L through a connection transformer (t) is therefore small, and the output of a correlative matched filter 12 thereby also becomes small, and synchronous detection becomes impossible. Even in the state where the train A is in process of detection, since the level state of a narrow zone signal component (deviation frequency component) is always checked in the coincident state of PN mark (PN1) and a circuit after a reverse diffusion circuit 15, noise in the output of the correlative matched filter 12 is effectively removed. Thus the excellent signal detection of S/N can be carried out, and train detection being excellent in antinoise property can be carried out.
