Title: Vibration removing device for cooling focal plane
Inventor: FUJII GENSHIRO
IPC: G01J1/02
Filed: 1987-12-10
Abstract: PURPOSE:To obtain the device which can remove fundamentally the vibration of a refrigerator to an infrared detector by floating the infrared detector by the repulsion of a superconductive magnetic field. CONSTITUTION:The superconducting focal plane 2 coupled thermally with the infrared detector 1 is made of a superconducting material and join temperature is made uniform to hold the detector 1 at constant temperature. A superconducting cold head 3 is cooled to cryogenic temperature by a cooling machine cold stage 7 made of a superconducting material coupled thermally. This baffle 6 is also cooled to cryogenic temperature by the stage 7. Therefore, when the detector 1 is in operation, the plane 2 floats over the head 3 by a repulsive magnetic field and stays at a stable position. In this state, cooling to below superconduction transition temperature is performed by a radiant heat exchange among the detector 1, the plane 2, the head 3, a nonmagnetic support member 4, and the baffle 6. Then a superconduction displacement detector 5 detects the displacement of the detector 1 and head 3 when they are displaced by the vibration of the stage 7, and then controls them to their reference positions.

Title: Image pickup device
Inventor: KANEDA SADAFUMI
IPC: H04N5/372
Filed: 1991-10-31
Abstract: PURPOSE:To obtain an image pickup device capable of obtaining sample value analog signals maintaining the independence of picture elements corresponding to picture elements on a CCD. CONSTITUTION:A signal obtained from the CCD l is color-separated by a color separating circuit 5 through a CDS(correlation double sampling circuit) 3.

Respective R, G and B signals obtained through matrix circuits 8, 11 and R, G and B signals outputted from the circuit 17 are inputted to a switching circuit 15. Since the circuit 17 executes only linear sequential interpolation, a sample value analog value maintaining the independence of picture elements are obtained from output amplifiers 12 to 14 by selecting the outputs of the circuit 17.

Title: Tank facility with pressure discharging device
Inventor: NISHI SHIGETO
IPC: F15B1/26
Filed: 1998-11-05
Abstract: PROBLEM TO BE SOLVED: To prevent a pressure tank and a supplementary unit from being deformed and broken caused by the operation of a discharging device when pressure is abnormally increased, by running a pipe from an upper cover part of the pressure tank, providing a U-shaped pipe by disposing its U-shaped part on the lower side, and making a pipe opposite to the tank side release to the atmosphere. SOLUTION: A case of a compressor 1 is filled with high-pressure gas and partitioned from a bearing box by a shaft seal mechanism. In a case where the shaft seal mechanism is broken in this state, high-pressure gas in the compressor case is leaked into the bearing box, and pressure in the bearing box is suddenly increased and transmitted from an oil discharging pipe 3 to a tank 4. At this time, tank internal pressure is increased, liquid in a U-shaped pipe of a pressure discharging device 12 is ejected, pressure in the tank is discharged to restrain tank internal pressure from being increased, and therefore, a supplementary unit such as the tank 4, the oil discharging pipe 3, an exhaust gas discharging blower 8 and a level gauge 9 is protected.  When pressure is abnormally increased, the discharging device is operated, and therefore, the pressure tank and the supplementary unit can be prevented from being deformed and broken.

Title: Brush for endoscope
Inventor: OKADA SHINSUKE
IPC: A61B1/00
Filed: 1998-11-05
Abstract: PROBLEM TO BE SOLVED: To enable the insertion of a brush into an endoscope pipeline by intertwining many slender strands to form a rope insertable and removable into and from the pipeline of the endoscope and unraveling its one end side, thereby forming a brush hair part. SOLUTION: The twisted wire rope of about 0.9 mm in diameter is formed by using for example, 49 pieces of the strands 1a of fine stainless steel wires of about 0.1 mm in diameter and intertwining these strands to 7×7. The rope which is insertable and removable into and from the endoscope pipeline is formed by using these rope as a blank. This rope is formed longer than the overall length of the endoscope pipeline, to for example, about 1 mm and is held as it is at the shape of the rope exclusive of its both ends. The strand twists at one end of the rope are unraveled to form the brush hair part. A fixing part is formed at the root part of the brush hair part to prevent the loosening of the twists in the rope part. The other end of the rope 1 is provided with a hemispherical front end fixing part.  As a result, the insertion of the brush hair part into the endoscope pipeline and the cleaning thereof are made possible.

Title: Track jump control circuit
Inventor: EBARA KAZUNORI
IPC: G11B7/00
Filed: 1991-11-28
Abstract: PURPOSE:To certainly stop at a target track by providing 1st and 2nd pit reproducing signal detecting parts, a record/nonrecord discriminating part, a brake signal generating part and a changeover switch. CONSTITUTION:A read signal RFI of a pickup is inputted to the discriminating part 4, where a peak value is detected and is compared with a reference value. The changeover switch (SW) 6 is selectively changed to make a terminal 6c select terminals 6a and 6b based on a signal corresponding to a discriminating result. The signal is compared with a reference value by a waveform shaping circuit 12 in the 1st detecting part 1. When the RFI is in a part corresponding to a nonrecorded track, a signal MIRR is not generated. The same is the case with the 2nd detecting part 5 where the comparison with a reference value is made to output a signal mirr, and the signal MIRR corresponding to a level of the mirr is inputted to a terminal D of the brake signal generating part 3. An input of a TEI signal detecting part 2 is waveform-shaped, and is edge-detected to generate a CLK signal. An output of a brake signal BRK is controlled with a level of the MIRR at the time of inputting the CLK. A digital signal by a waveform shaping circuit 21 is counted by a control system which is not shown in the figure, and the control is performed when the number of tracks to be traversed becomes a target value, and the jump is stopped.

Abstract: PURPOSE:To efficiently perform the recovery processing at the time of the occurrence of trouble preventing contradictions of data in an application file and without the unnecessary use of computer resources by performing not only protection control dependent upon exclusive control of an application file but also confirmation of the processing state and update of the application file for the unprocessed state. CONSTITUTION:During the processing of a designated application related to the interlocking processing in a start request destination computer 2, not only protection control dependent on the exclusive control of an application file is performed for the purpose of preventing contradictions of contents of the application file 14 to be updated in a start request source computer 1 but also the control processing of data transmission/reception between computers 1 and 2 is so performed that the application processing is independently executed and concluded. At the time of the occurrence of trouble, a cancel instruction is not outputted from the start request source computer 1 to return an application file 24 in the start request destination computer 2 to the state before processing, but output the processing confirmation and reprocessing instruction to confirm the processing then instruct the reprocessing if confirmed that the application file is not update. Thus, the recovery processing is simplified to prevent the unnecessary use of computer resources due to the cancel instruction.
