Title: Complementary output light source
Inventor: MASUDA SHIGEFUMI
IPC: G02B6/287
Filed: 1985-06-28
Abstract: PURPOSE:To obtain coherent light even from light source light of low coherency by bringing blocks into contact with each other with inclination and disposing two fibers in such a manner that the fibers are folded back interdigitally from each other and are coupled to each other. CONSTITUTION:The fiber 11 (extending to a-a') is embedded in the block 15 and the fiber 11 is cut by cutting off and polishing the fiber except the core shown by a black dot on a plane 13. The fiber 12 (extending to b-b') is similarly embedded in the block 16 and is similarly cut on a plane 14. The fibers 11, 12 are embedded in the blocks 15, 16 and the surfaces of the respective blocks are cut off and cut by polishing in such a manner that the cores of the respective fibers remain. The cut planes 13, 14 of the respective blocks are brought into contact with each other with the slight inclination and the fibers 11, 12 are so disposed as to be folded back interdigitally from each other and are coupled to each other. Then the light is propagated into an arrow direction in the fiber 12 by the interference when the light is propagated in the arrow direction into the fiber 11. The device acts as a light coupler.

Abstract: PURPOSE:To realize a displayed picture of uniform brightness by reversing polarity of of voltage applied to a common electrode for each field by polarity inversion of picture element voltage and antiphase and increasing the absolute value gradually from the starting point to end point of the field. CONSTITUTION:A sample hold circuit 24 holds successively picture element voltage for 1 line sent from a polarity inversion circuit 23 synchronously with timing of a shift register 22 and supplies all at once to corresponding switching element string gij-gmj of a picture element electrode group of the line.

Further, a pulse modulation part 5 consists of a pulse width modulating circuit 6 and the driving circuit 7 and the circuit 6 is driven with a signal from an input/output terminal 8 for synchronism. Then, the output of an amplifying circuit 4 which amplifies the output of the temperature sensing body 1 is pulse- modulated by a modulation part 5 as specified. The output of the modulation part 5 has its higher harmonic component removed when passing through a low-pass filter 9 and is fed back to the heater 3, which generates heat to hold the temperature sensing body 1 at the specific temperature.

Title: Data transfer compensation output buffer
Inventor: TAGISHI MITSUAKI
IPC: H03K19/0944
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To allow an output buffer to correspond to transmission channels different from each user by providing a means controlling veriably a delay value and a through-rate value so as to conduct prescribed data transfer even when the environmental condition and the process condition are fluctuated. SOLUTION: A control circuit 12 controls a delay value of a delay circuit 8 and a through-rate value of a through-rate circuit 7. The control circuit 12 is composed of an N-channel MOS transistor(TR) 14 in the inside of the chip and an externally mounted resistor 13 and acts like a kind of detection circuit. When the environmental condition and the process conduction are fluctuated in a direction to increase an operating speed of the TR, the on-resistance of the N-channel MOS-TR 14 is decreased and a potential at a point E changes decreasingly. Since the potential at the point E is supplied as a control signal, the output buffer itself is operated to slow down the operating speed. Conversely when the conditions are fluctuated in a direction to slow down the operating speed of the TR, the potential at the point E changes increasingly.

Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To absorb and damp hammering noise of an air hammer during excavating work to reduce noise to a minimum by charging sound absorbing material in a space part between the air hammer and a casing. SOLUTION: A support ring 14 having a clearance to the outer peripheral surface of a hammer body 8a is fastened to the inner peripheral surface lower end of a casing 7 for a hammer. A partition wall 15 surrounding the body 8a is disposed between the support ring 14 and a holding plate 9b of the casing 7, and sound absorbing material 16 is charged in a space part between the outer peripheral surface of the partition wall 15 and the inner peripheral surface of the casing 7. A synthetic resin foam body, unwoven fabric, or the like is used as the sound absorbing material 16, and impact sound is absorbed and damped by a large number of air layers and resiliency. Storing hammering noise generated by the drive of the hammer 8 during excavating work are therefore absorbed and damped by the sound absorbing material to reduce noise.  Work environment is therefore improved to avoid noise pollution around a construction site.
