Title: Optical heterodyne/homodyne detecting receiver
Inventor: HONMO HIROSHI
IPC: H04B10/61
Filed: 1985-08-28
Abstract: PURPOSE:To reduce the attenuation of signal light by obtaining monitor light for automatic polarization compensation from the 2nd light output terminal of a photocoupler for synthesizing the signal light and locally oscillating light. CONSTITUTION:The 1st and 2nd polarization controllers 16, 17 respectively constituted of a single mode optical fiber are cascade-connected between the light output terminal of an optical transmission line 1 and the 1st light input terminal 3 of the photocoupler 2 and pressure is applied to the single mode optical fibers by a voltage driving PZT from the direction rectangular to the optical axis of the single mode optical fibers to control polarization. The 1st polarization controller 16 controls polarization so that one of the main axis of polarized light of the output light from the optical transmission line 1 is made parallel with the surface of paper and the 2nd polarization controller 17 executes its control so that linearly polarized light polarizing the elliptically polarized light outputted from the 1st controller 16 in the direction parallel with the paper surface is obtained. Since signals for the control of the 1st and 2nd coontrollers 16, 17 are taken out from the 2nd light output terminal 6 of the photocoupler 2, the attenuation of the signal light can be reduced by the insertion loss of a polarized beam splitter or a mirror which was ordinally used.

Title: Levelness measurement device
Inventor: WAKASA MASAAKI
IPC: G01C7/04
Filed: 1993-08-02
Abstract: PURPOSE:To improve the accuracy and resolution of a measurement value by irradiating a horizontal laser beam, while causing the travel of a movable body having many vertically arrayed photo sensors. CONSTITUTION:A column 10 is fixed on a bogie 4, and a vertically slender sensor aggregate 12 is fastened to the side of the column 10. The sensor 12 consists of units containing photo sensors SN to S1 arrayed at constant intervals. Furthermore, the bogie 4 is placed on a plane R as a measurement object. Then, a laser beam is horizontally irradiated toward the photo sensor 12 from a laser beam transmission section 2 on a support body 1 secured to the ground. As the sensor Sn at the same height as the section 2 receives an optical beam, data about the height of the position is obtained from the output signal of the sensor Sn. In addition, when a measurement start signal is generated from an initiation signal generation section, a height data memory section takes in height data for every constant time, upon the generation of the signal, and continues to save the data. As a result, the height fluctuation of the plane R can be continuously recorded by causing the bogie 4 to travel at constant speed concurrently with the generation of the measurement initiation signal.

Title: Conductive adhesive
Inventor: MORIMOTO HIROSHI
IPC: H05K1/09
Filed: 1991-07-31
Abstract: PURPOSE:To lessen unevenness of bonding strength, stabilize it and enhance a dispensation property by using a granular shape or spherical grain powder in a silver powder having a specific maximum grain size, the specific range of an average grain size and a specific minimum aspect ratio. CONSTITUTION:A silver powder is defined as its maximum grain size is 20mum and its average grain size is within the range of 3 to 10mum, thereby dispersiveness is enhanced, thixotropy is heightened, the sag thus is not generated at the time of dispensation, and clogging a dispenser with coagulated grains can be prevented. Since conductivity of a conductive adhesive is heightened by enhancing the dispensation property and reducing the contact resistance between the silver grains, the electric characteristic can be improved. Further, by using the silver powder of a granular shape and spherical grain having an aspect ratio of 0.5% or more, a coating area of the silver powder is made small in an adhesive interface between an element and a lead frame and a resin area is made relatively large to reduce the interfacial breakage. As a result, the bonding strength is heightened, its unevenness is lessened and stabilized, and the dispensation property can be enhanced.
