Title: Adjusting method for diffraction grating of optical pickup
Inventor: OHAMA YUZO
IPC: G11B7/08
Filed: 1986-08-06
Abstract: PURPOSE:To make movement of an optical pickup to the position of a mirror at each time of adjustment unnecessary by comparing and observing the signal waveform of a track obtained with one auxiliary spot and that obtained with the other auxiliary spot and adjusting a diffraction grating in accordance with the interval of appearance of signal strings having the same waveform. CONSTITUTION:In case a spot 13 is put on one track, an auxiliary spot S1 of the spot 13 describes a waveform (b) when an auxiliary spot S2 describes a waveform (a). The same waveform appears on waveforms (a) and (b) at an interval (d). The interval (d) is determined by the distance between auxiliary spots S1 and S2 and the linear speed of a disc 6. If auxiliary spots S1 and S2 are arranged on tracks between which two tracks exist, this interval is too long to observe the appearance of the same waveform. Consequently, a diffraction grating 2 is adjusted by rotation so that the same waveform appears. Thus, it is unnecessary to move the optical pickup to the position of the mirror.

Abstract: PURPOSE:To improve the freedom in profile by a method wherein the title manufacture is composed of the process bringing about the amorphous alloy state comprising the stoichiometric composition of metallic elements comprising the objective oxide superconducting material and the process oxidizing the amorphous alloy. CONSTITUTION:In order to manufacture an amorphous alloy out of yttrium base superconducting material (Y1Ba2Cu3O7-y) by single rolling process, a metallic powder mixed in the ratio of Y:Ba:Cu=1:2:3 is fed into a crucible 1 to be heated and melted down using high-frequency coils 2 and then high pressure argon gas is led into the crucible l by a pressure regulator 5 to spray a melted solution over a roll 4 from a stopper nozzle 3. This roll 4 is structured to be driven at high speed so that cooling water may be fed to the inside. The ribbon type amorphous alloy is processed while being pressurized in vacuum atmosphere at relatively low temperature to relieve the structure and successively this film is heat-treated in oxygen atmosphere to form a superconductor layer. Through these procedures, the superconducting layer can take the specific shape while keeping the superconductivity.

IPC: H04L23/00
Filed: 1984-09-04
Abstract: PURPOSE:To prevent the occurrence of an underflow in buffer memory by issuing a transmission request signal from an encoding part when one side of the buffer memory is full, and transferring and controlling data stored in the buffer memory side to an output control part with the transmission request signal and a reception request signal from an output control part. CONSTITUTION:A facsimile image signal which id displayed in black/white binary values and inputted from an input terminal 1 is converted by an encoding part 2 to write it in one of plural built-in buffer memories. When said memory is full or conversion data of input signals of the prescribed number of lines are accumulated, the transmission of data is demanded to a control part 4, and simultaneously said buffer memory is switched to another memory to continue writing of the conversion data. On the other hand, an output control part 3 incorporates two buffer memories, reads out the data written in one memory at a constant speed and outputs it to a facsimile device from an output terminal 5. When the data in said memory becomes empty, the output control part 3 requests the control part 4 to receive the data and simultaneously said buffer memory is switched to the other to read and transmit data.

Abstract: PURPOSE:To obtain the detecting device which grasps an invariably accurate position by integrating the angular velocity voltage obtained by subtracting a voltage stored in a zero-voltage storage means from the output voltage of an angular velocity sensor when a radio wave from an artificial satellite cannot be received. CONSTITUTION:This system normally calculates the latitude, longitude, and altitude of the current position of a vehicle with signals received from three satellites, reads map data on the neighboring position out of a CD-ROM 3, and displays the data on a CRT 4. When, however, the vehicle moves to a place where a radio wave is not received from an artificial satellite, a data processor 5 performs switching to a method which calculates the position from the position which is found last by using the artificial satellites with signals from a tuning-fork vibration type angular velocity sensor 6 and a vehicle speed sensor 8. Then the angular velocity voltage obtained by subtracting the voltage stored in the zero-voltage storage means from the output voltage of the sensor 6 is integrated to calculate the variation angle of the current travel direction of the vehicle and also calculate the travel direction of the vehicle, and the current coordinates of the vehicle in a travel on the map are calculated from said calculated value and the movement quantity of the vehicle detected by the vehicle speed sensor 8.

IPC: F24D11/00
Filed: 1983-10-04
Abstract: PURPOSE:To contrive to reduce the heating load by raising the temperature of underground water to be pumped up from a pumping well by a method wherein heat is accumulated in pebbles during the hot water filled in a return well flows in underground water bearing strata. CONSTITUTION:When the temperature of hot water in a medium temperature heat storage tank 4 is raised up to the set value, a return pump 14 is put into operation so as to return the hot water in the medium temperature heat storage tank 4 through a return pipe 12 in a return well 9. When the water level in the medium temperature heat storage tank 4 lowers down to the predetermined value, an FM valve 17 is opened and underground water is pumped up from a pumping well 11 through a lift pipe into the medium temperature heat storage tank 4 by means of a pressure water feeder 18. During the hot water filled in the return well 9 flows in underground water bearing strata 10 with no pressure therein towards the lift well 11, the heat contained in said hot water is absorbed and accumulated by pebbles. The underground water supplied to the medium temperature heat storage tank 4 absorbs heat and raises its temperature while flowing in underground water bearing strata 10 with no pressure therein. Thus, the effective utilization of excess heat during the summer season and the reduction of heating load during the winder season and the like are performed.

IPC: G09F3/03
Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To provide a sealing device for a housing which makes it possible to easily and accurately confirm that the housing sealed containing a specific device is illegally unsealed.

An insoluble solid matter aggregated from the pressed juice is finally separated by, e.g. centrifugation. The heating is preferably conducted for about 1 sec to 10 min. The cooling may be either instantaneous cooling according to a plate type or slow cooling with a jacketed tank. The centrifugation is carried out at about 500-1,000 r.p.m. rotational frequency in the case of performing the separation by the centrifugation.

Title: Image reader
Inventor: SAWADA MITSUSHI
IPC: H04N1/19
Filed: 1989-07-20
Abstract: PURPOSE:To always obtain a satisfactory read image by starting the subscan of the original image of a line image sensor after awaiting an operation until the peak value of a picture signal exceeds a constant value, and reading the image sequentially. CONSTITUTION:When environmental temperature is low, the output level of the picture signal of a CCD line image sensor 104 is also decreased due to the reduction of the initial light quantity of a fluorescent lamp 103, and the signal level of the picture signal VD is also decreased. Then, a constant value vS set at a comparator 109 in advance is compared with the peak value vP of the picture signal VD for the output level of the picture signal VD in a stationary state, and assuming that the environmental temperature is low and the peak value vP is less than the constant value vS, the operation is awaited. When the fluorescent lamp 103 is lit, then, the light quantity of the fluorescent lamp 103 is increased gradually and the signal level of the picture signal VD is also increased and the peak value vP of the picture signal VD exceeds the constant value vS, the subscan control of an original DP is started with a scanner 1. Thus, since the light quantity of a light source is increased, then, the original image is read after the S/N of the picture signal is increased, the satisfactory image can always be obtained.
