Title: Scintillation camera having split light guide tube
Inventor: SEBASUCHIYAN JIENNA
IPC: G01T1/202
Filed: 1988-09-02
Abstract: PURPOSE: To couple a photodetector effectively with a scintillation material by providing a scintillation material emitting light in response to absorption of radiation, a photodetector, and a plurality of segments. CONSTITUTION: A scintillation camera 10 comprises a polygonaliy split optical waveguide 12 for coupling a photodetector 14 optically with a scintillation crystal 16. The waveguide 12 comprises separated segments 17, 18, 20, 22. The separated segments can be assembled inexpensively and can be arranged easily with a scintillation material on the intermediate plane regardless of the shape thereof. When the photodetector is coupled optically with the scintillation material utilizing the split optical waveguide, an effective scintillation camera can be realized at low cost.

Title: Galvano-mirror unit
Inventor: KUWATA NAOKI
IPC: G11B7/09
Filed: 1989-08-28
Abstract: PURPOSE:To use only one mirror to make the title unit easily adjustable by performing operations to deflect a light beam in the radial direction and tangen tial direction of the information track of a recording medium by means of the mirror and using a laminated piezo-electric element for driving the mirror. CONSTITUTION:Four laminated piezo-electric elements 31a-31d are fixed on the X and Y axes on the rear of a mirror 21 in the vicinity of the outer periphery and other ends of the elements are fixed to a fixing section 32. When such a voltage that elongates the element 31a and contracts the element 31b is applied across the elements 31a and 31b, the mirror 21 rotates in one direction around the Y axis. When a voltage of the opposite polarity is applied across the elements 31a and 31b, on the other hand, the mirror rotates in the opposite direction around the Y axis. When similar operations are made by using the elements 31c and 31d, the mirror 21 can be rotated around the X axis. Therefore, when such operations are simultaneously performed, the mirror 21 can be deflected by a desired angle. Therefore, adjustment of this galvano-mirror unit can be adjusted easily in optical axis by only one mirror and the number of parts can be reduced.

Title: Manufacture of single-crystal semiconductor substrate for semiconductor sensor, and semiconductor sensor
Inventor: UKAI SEIICHI
IPC: H01L21/306
Filed: 1991-09-02
Abstract: PURPOSE:To reduce the variation of sensor output by constituting a sensor having a hollow region from one 14-type semiconductor single-crystal substrate. CONSTITUTION:A sensor diaphragm 2 is composed of the same maternal(N-type single crystal) as that of a substrate 1 and further has a structure where no bonding is carried out. Also, the small hole of a diaphragm 2 opened for forming a hollow part 3 is filled and closed by a cap 4. Moreover, a piezoresistance element 5, of which the value of resistance varies by a change of stress, is provided on the surface of the diaphragm 2 corresponding to the periphery of the hollow part 3. When pressure is applied to this sensor, the diaphragm 2 changes shape and a large force acts upon the periphery because the pressure of the hollow part 3 is almost constant. In this case, because the value of resistance of the piezoresistance element 5 changes, the pressure is measured by the detection of the value. Thus, it is possible to reduce the variation of sensor output.

Title: Method of brazing ferrous metal
Inventor: BURAIAN BAANAADO BONAA
IPC: B23K1/008
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a brazing method of ferrous metal which provides a good flow of brazing filler metal, a brazed joint of good quality and no soot at the brazed joint.
