Title: Magnetic recording and reproducing system
Inventor: OKAMURA SHIROU
IPC: G11B5/008
Filed: 1980-05-09
Abstract: PURPOSE:To form parallel recording tracks at a time on a medium and then carrying out a reproducing action, by using plural heads having different azimuth angles. CONSTITUTION:The parallel recording tracks 2-7 or the like are produced on a magnetic tape 1 with different azimuth angles. The recording tracks 2 and 3 plus 4 and 5 are scanned simultaneously at different times, and tracks 6 and 7 also receive the same scan.

IPC: G01L11/00
Filed: 1993-02-26
Abstract: PURPOSE:To finely measure the distribution of pressure applied directly to a rubber mold stress cone by arranging a piece of or a plurality of optical fiber pressure-sensitive sensors in the rear of the rubber mold stress cone, and monitoring the mounting pressure of the rubber mold stress cone, using this. CONSTITUTION:A rubber mold stress cone 4 is made by integrally molding the conductive rubber part 2 on rear side and the conical insulating rubber part 3 on the side of a pointed end. And, an optical fiber pressure-sensitive sensor or a rubber optical fiber pressure-sensitive sensor 1 is arranged in spiral shape at the rear, where a press metal fitting abuts, at the right of the conductive rubber part 2. Accordingly, the distribution of pressure applied to the rubber mold stress cone 4 can be measured accurately with the sensor 1, and besides, since this measures it with a light, it becomes possible to always measure the pressure distribution without being affected at the connection at current application.

Title: Surgical operation apparatus
Inventor: KARASAWA HITOSHI
IPC: A61B18/00
Filed: 1988-03-14
Abstract: PURPOSE:To efficiently excise a part to be treated in such a state that a meniscus is certainly fixed and to perform treatment within a short time, by a method wherein the leading end part of the vibration transmitting member of an ultrasonic suction apparatus is brought into contact with the curved part provided to the leading end of a fixing jig and slides along the curved part to be moved in the direction right-angled to an insert direction. CONSTITUTION:The insert part 19 of a fixing jig 13 inserted in a joint cavity along with a vibration transmitting member 3. Finger rests 18 are grasped so that the curved parts 21 of the leading end of the fixing jig 13 protrude toward the vibration transmitting member 3 as shown by Fig (a) to grasp the damage part 26 of a meniscus 24. An ultrasonic suction apparatus 2 is operated to further insert the vibration transmitting member 3 in the joint cavity to excise the damage part 26. When the vibration transmitting member 3 is inserted, the leading end thereof moves along the radius of curvature of the curved part 21 while performs excision. Since each of the curved parts 21 has the radius of curvature near to the inner diameter of the meniscus 24, the vibration transmitting member 3 is moved using the curved parts 21 as guides to excise the damage part 26 and the excised surface can be made smooth.

Title: On-train public address mechanism for vehicle of railroad or the like
Inventor: NISHIYAMA TOYOO
IPC: B61L25/02
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To simply and easily confirm the performance of a public address(PA) system and the presence and absence of a fault at the time of the test or the fault of the PA system in a driver's cabin by providing a microphone for detecting a reference signal sound from a speaker for on-vehicle PA so as to detect the normal/abnormal state of the on-train PA system by the level of the reference signal sound from a microphone. SOLUTION: A signal for inspection is emitted from a reference signal generator and amplified by a microphone amplifier. A reference signal power-amplified by a PA amplifier is emitted into the vehicle as voice from a speaker for on- train PA. The voice is received by a receiving microphone installed in the vehicle, and a received voice controller executes amplification, level-comparison and the judgment on passing or not the inspection to the voice and gives a vehicle number address for discriminating vehicles. Then, the sound passes through a transformer T3 and PA lines L, L2 from a transformer T2 and passes through the transformer T1 of a PA controller to be inputted to the transformer 2, and a PA control display displays the vehicle number address and an inspection result.

Title: Spindle motor
Inventor: OSAWA HARUSHIGE
IPC: F16C19/06
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To obtain a spindle motor which maintains the existing size or reduce the size and assures good bearing performance, by displacing a ball bearing to the axial center of the inner ring or outer ring of rolling element, and them providing face to face the end faces in the longer isolation distance from the rolling element. SOLUTION: Length of axial direction of inner and outer rings 1, 2 is set larger than the existing size, such increment is extended in the side where a pair of ball bearings 5, 7 are provided face to face, and the rolling element 3 is loaded with deviation from the center position in the axial direction (for example, the ball bearing 6 is deviated to the upper side and the ball bearing 7 to the lower side). As explained above, since the ball faces 8, 9 having the longer isolation size M from the rolling element 3 are provided opposed with each other, the spindle motor can reduce the inclination of the inner and the outer rings 1, 2 without increasing the length in the axial direction longer than the existing length.  Accordingly, the rolling element 3 which plays like the existing one can be eliminated, thereby preventing degradation of bearing performance and rotating performance of spindle motor.

Abstract: PURPOSE:To improve the heat exchange efficiency of an air pre-heater, by providing a rotor's upper position detector at a portion remote from a seal plate in the reverse direction of the rotor's revolution, and measuring distortions on the upper portion of the rotor in advance so as to maintain the sealing clearance to minimum. CONSTITUTION:A rotor's upper position detector 8 is mounted at a portion remote from a seal plate 1 in reverse direction of rotor's rotation, and measures a distance between the upper position of the rotor and the upper limit position of the seal plate to input it to a control device 7. A period of time required for the upper position of a control rotor to move a distance from its upper limit to its lower limit, and the initial value of the seal plate 1 are input to calculate an optimum position of the seal plate 1. The optimum position is defined as a position satisfying both conditions that the upper position of the rotor in continuous rotation is close enough to the back surface of the seal plate without coming into contact with the seal plate, and the upper position of the rotor in moving is close enough to the seal plate without coming into contact with the right lower edge of the seal plate while the seal plate is in ascending operating to correct its position. When the conditions are not satisfied, the seal plate is moved upward or downward by operating a motor 4, and the control is continuously carried out until the rotor stops.

Title: Separation purification method of macromolecule of living body
IPC: B01D15/08
Filed: 1992-03-18
Abstract: PURPOSE:To reduce the amount of buffer liquid for washing and miniaturize a buffer liquid storage tank and then reduce waste liquor throughput by recycling after eliminating an Impurity from the buffer liquid after washing without virtually changing the salt concentration. CONSTITUTION:A detection piping 16 with a detector 6, a piping 17 for supplying a washing liquor waste to an impurity separation means 7, a liquid waste delivery piping 18, and a collection piping 19 of a collection liquid are connected to an effluent extraction piping 15 of a separation column 5. A reproduction buffer liquid whose impurities were separated by an impurity separation means 7 is returned to a buffer liquid container 3 for washing through a piping 20. When a separation method by a precision film separation device is used as the impurity separation means 7, only impurities are eliminate from the washing liquor waste by using a precision separation film with a proper thin hole which does not allow impurities such as an unneeded protein to be transmitted but allows salt within the buffer liquid or buffer liquid components to be transmitted. A penetration liquid which is obtained by this sort of film separation treatment has the same composition as that of the buffer liquid, thus enabling it to be recycled.
