Title: Thick film ultrasonic optical switch
Inventor: HASUMI RITSUO
IPC: G02B6/12
Filed: 1980-01-19
Abstract: PURPOSE:To obtain the thick film ultrasonic optical switch which is small-size and has a high energy efficiency, by interposing upper and lower faces of the ultrasonic transducer and the ultrasonic medium, which are processed into several tens mum thickness, between clad layers and by arranging thick film lenses before and after them and by connecting end faces of I/O optical fibers thereto. CONSTITUTION:The first clad layer 2 is formed on substrate 1, and lenses 3 and 4, ultrasonic transducer 5, and ultrasonic medium 6 are arranged, and core layer 7 is formed, and they are coated with the second clad layer 8. End faces of input fiber 10 and output fibers 11 and 12 are connected to focuses of lenses 3 and 4. Ultrasonic wave absorbent 9 is fitted to a part of ultrasonic medium 6. Light 13 incident from fiber 10 is propagated through core layer 7 and becomes parallel light beam only in the plane directionly lens 3. When high-frequency power source 15 is connected to electrode 14 of ultrasonic transducer 5, light 13 is subjected to Bragg's reflection, and connection is switched from fiber 11 to fiber 12 by lens 4. Consequently, the optical switch is small-size and has a high energy efficiency.

Title: Dry type electrophotographic device
Inventor: EGUCHI YUJI
IPC: G03G15/09
Filed: 1988-01-13
Abstract: PURPOSE:To drive a electrifying part and a developing part by a common high voltage generating circuit by delaying the timing for starting to rotate the sleeve and the magnet roll of a developing part, from an applied time of a high voltage. CONSTITUTION:The driving start of a sleeve 5a and the magnet roll 5b of a developing part 5 is delayed by a prescribed time T0 from a high voltage output time. Accordingly, even if negative high voltages Vc, Vb are applied by the same timing to the sleeve 5a of an electrifying part 2 and the developing part 5, the developing part 5 does not operate immediately, therefore, it does not occur that a magnetic toner sticks to the outer peripheral surface of a photosensitive drum 1 which is not electrified yet. In such a way, the magnetic toner is not consumed uselessly, and also, it becomes unnecessary to separate a high voltage generating circuit by the electrifying part 2 and the developing part 5 and to install two sets.

IPC: A01M29/00
Filed: 1980-01-22
Abstract: PURPOSE: The titled rope without losing its effects in a wide temperature range for a long time, obtained by attaching pressure-sensitive adhesive for repelling birds prepared by blending polybutene with colloidal silica and diethylhexyl adipate to a rope or string.  
     CONSTITUTION: 100pts.wt. polybutene is blended with 3W15pts.wt. colloidal silica exhibiting cold flow preventing effects and colorless transparency and 5W20pts.wt. diethylhexyl adipate exhibiting low-temperature characteristics to give a pressure- sensitive adhesive for repelling birds. To make birds not approach building structures, the surface of a rope or string is covered with the adhesive evenly. The prepared rope or string can exhibit repulsing effects against any kinds of birds by changing properly the thickness of the rope or string. It has improved workability and stability in its application and can be applied to any place or space readily, so long as there are spots to fix the rope. The rope can be carried readily to sites where it is used, and an amount of the adhesive to be used is small.

Title: Electronic switch
Inventor: MIYAMOTO KIYOSHI
IPC: H03K17/082
Filed: 1984-01-18
Abstract: PURPOSE:To attain an electronic switch with ease of use by enabling the short- circuit protection to be released by simply spacing away an object to be detected from a sensor circuit even if the short-circuit state is eliminated with a load short-circuited. CONSTITUTION:When an object approaches a proximity switch with the load L short-circuited, a sensor circuit 10 outputs an NL output, and a large current flows to a thyristor 6 and an FET7, but a power voltage given to the sensor circuit 10 is limited by a constant voltage circuit 9 and the short-circuit current is limited by the constant current characteristic of the FET7. Just thereafter, the thyristor 8 is turned on by a voltage division circuit comprising resistors R22, R23. Thus, the short-circuit current is cut off by the FET7. After the short-circuit state is finished, if the proximity switch detects no object, the NL output restores to L to stop the holding of the thyristor 8. Thus, the short-circuit state is eliminated, the state restores automatically to the stand-by state.
