Title: Light integrated type interferometer
Inventor: TAKI KAZUYA
IPC: G02F1/095
Filed: 1990-09-12
Abstract: PURPOSE:To enable measurement with an improved S/N ratio by combining a mode converter and a mode splitter or a Y branch waveguide and a mode filter to prevent the reflected light from an object to be measured from returning to a light source. CONSTITUTION:A laser light reflected from an object 43 to be measured is subjected to a Doppler shift by a frequency fs according to a speed. The resulting signal light is introduced to a ridge type waveguide 37 with an index distribution-type light waveguide 41 and passes through a mode converter 36 again to cause a 50% mode conversion while the remaining TE mode is turned to a TM mode completely. A mode splitter 34 is made up of two parallel light waveguides 45 and 46, a buffer layer 47 and a metal clad 48. As a result, the TM mode impinged into the light waveguide 46 from the mode converter 36 does not move to the waveguide 45 but propagates through the waveguides 46 and 49.

Title: System for receiving exhaust gas pressure of exhaust gas boiler
Inventor: TOYOMARU MAKOTO
IPC: F22B1/18
Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To reduce the weight of a system for receiving exhaust gas pressure of a vertical gas flow type exhaust gas boiler having a denitrification device by changing a horizontal orientation of back-stays to a vertical orientation of back-stays. SOLUTION: A plurality of boiler supporting hot beams 1 passing through a side wall casing 11 are provided at an upper part in parallel with each other. The beams are enclosed by a front wall casing 9, a rear wall casing 10, right and left side wall casings 11. Within them are provided groups 7, 8 of upper and lower heat transfer pipes, a denitrification device 3 and a header supporting device 12. The right and left side wall casings 11 are provided with a plurality of side walls and lower side wall vertical back-stays 13, 13'. Each of them is connected to a denitrification device supporting beams 2 at a central part of each of them.  The upper end of the back-stay 13 is connected to the hot beams 1 and the lower end of the back-stay 13' is connected to a bottom face back-stay 14 so as to make a balanced state of pressure between rightward-directed exhaust gas and leftward-directed exhaust gas. Pressure of exhaust gas at the forward part is well balanced with that at the rearward part in the system through the supporting device 12 and the side wall casings 11. Since the back-stays are arranged in vertical orientation in place of their horizontal orientation so as to eliminate the forward back-stays and the rearward back-stays, their weight can be reduced.

Title: Image pickup device
Inventor: TSUDA YUJI
IPC: H04N5/235
Filed: 1992-09-10
Abstract: PURPOSE:To prevent an S/N from being deteriorated due to the shortage of illuminance of an object by selecting a photographic mode provided with an area to control exposure at shutter speed in the area with frequency lower than field frequency before the gain of an AGC circuit is increased. CONSTITUTION:The exposure is controlled by combining three kinds of exposure control means for an iris 2, the AGC circuit 5, and the shutter speed (slow shutter) by keeping the light accumulation time of an image pickup element 3 longer corresponding to the illuminance of the object. Each setting value of an exposure control means in accordance with a selected photographic mode is read out of a data table memory 22 by selecting every kind of photographic mode by a photographic mode selection switch 21 by an operator, and the characteristic of an exposure control system is set by those information. Since exposure time can be changed successively even for a long period exceeding one field period by employing such constitution, it is possible to perform exposure correction in detail corresponding to the brightness of the object even when the illuminance of the object is insufficient.

Title: Angular velocity sensor, its resonance-frequency adjusting method and its manufacture
Inventor: ATSUJI KENICHI
IPC: G01C19/5755
Filed: 1994-10-06
Abstract: PURPOSE: To obtain an angular velocity sensor in which a resonance frequency in a moving part can be adjusted and to adjust the resonance frequency by etching and shaving any one of protective films by a method wherein the cross section of a support beam in the moving part is formed to be a quadrangle and the protective films against an etching operation are formed on either or both of the surface and the rear surface and both side faces of the support beam. CONSTITUTION: A support-beam part 12 is formed as a support beam 13 whose cross section is rectangular and which is made of polysilicon. Silicon nitride films 14 are formed on the surface and the rear surface, and silicon oxide films 15 are formed on both side faces. The protective films 14, 15 differ in their etching characteristic. In order to adjust a resonance frequency after the support beam has been manufactured, a resonance frequency in the horizontal direction B1, B2 and that in the vertical direction C1, C2 are measured and compared, and the direction in which the resonance frequecny is high is selected as an object to be adjusted. For example, when the resonace frequency in the vertical direction (detection mode) is high, the silicon nitride films 14 are shaved by CF4 /O2 /N2 mixed gas. The mixed gas does not affect the silicon oxide films 15.  When the resonance frequency in the horizontal direction (vibration mode) is large, the silicon oxide films 15 are ground by CHF3 gas.

Title: Thrust bearing device and water wheel generator
Inventor: INOUE TOMOAKI
IPC: H02K5/167
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To prevent a thrust pat during pressure oil lubrication from being inclined greatly in circumferential direction so that a front edge part can be lifted for the rotary direction of a thrust runner by forming the shape of the outer-periphery part of a pressure oil lubrication port in a structure where no dynamic pressure is generated at a rear edge part in rotary direction. SOLUTION: A guide bearing 11 for preventing a rotary shaft 1 from swinging is arranged at the outer-periphery side of a stoker part 9. A thrust bearing being constituted of a plurality of thrust pads 3 is arranged at the lower portion of a thrust runner 2, thus supporting the entire weight of the rotary shaft 1 with the thrust bearing. Since the thrust pad does not generate any dynamic pressure due to the low peripheral speed of the thrust runner 2 on activation, the thrust runner 2 is supported by a static pressure bearing operation using a lifter device at a low-speed rotary region. When the lifter device is activated, a pressure oil flows onto the slide surface of the thrust pad 3 and the thrust runner 2 by a pump 7, thus forming an oil film.
