Title: Deformation type optical switch
Inventor: KISHI YASUNARI
IPC: G02B26/02
Filed: 1982-03-31
Abstract: PURPOSE:To improve switching performance in a deformation type switch which utilizes the attenuation of the light generated by the deformation of the fiber formed by the external force exerted on an optical fiber as a switching effect by constituting the switch in such a way that the external force is applied at two places of the optical fiber at a 90 deg. algle difference from each other roughly at a right angle to the axial direction of the fiber. CONSTITUTION:When external forces FV, FH are applied to a pair of jigs 7, 8 and a pair of jigs 9, 10 toward the central axis of a fiber 6 at a 90 deg. angle difference from each other roughly at a right angle to the axial direction of the fiber 6, the fiber 6 is snaked minutely in the direction of a 90 deg. angle difference from each other. Therefore, while the fiber 6 is kept free from the external force, that is, it is not snaked as shown in the figure (a), light p passes through the fiber 6 with substantially no attenuation but when the external force F is applied thereon by means of the jigs 7, 8, 9, 10, the fiber 6 is snaked as shown in the figure (b), and part of the light P progresses in the fiber 6 while reflecting on the inside surface of the snaking position. The rest of the snaking position. The rest of the light advances rectilinearly. Thus, the light progresses in the fiber 6 while attenuating. A polarization characteristic is provided to this light P by the deformation of the fiber 6.

Title: Clock generator and information processing system using the same
Inventor: KURITA KOZABURO
IPC: H03L7/10
Filed: 1989-03-03
Abstract: PURPOSE:To surely synchronize the operation relating to a data processing including the data transfer between plural related information processing units by varying the range of the oscillating frequency of a voltage controlled oscillation means in response to the change in the frequency of a timing signal. CONSTITUTION:When the frequency of a timing signal is high, a compensation means 15 changes the range of the frequency oscillated by a voltage controlled oscillation means to a high frequency. Since the frequency range of the clock signal of a clock generating circuit is changed to a high frequency thereby, it is prevented that the frequency of the timing signal goes to the outside of the frequency range of a synchronizing clock signal. When the frequency of the timing signal is lowered conversely, the compensation means 15 is operated to change the frequency range of the synchronizing clock signal to the lower frequency. That is, the frequency range of the synchronizing clock signal is changed in response to the frequency of the timing signal. Thus, the inoperation of the clock generating circuit is prevented.

IPC: H01S5/00
Filed: 1990-03-02
Abstract: PURPOSE: To enable high-speed operation by cascading modulation-doped quantum well heterostructures in a semiconductor device. CONSTITUTION: A light signal 22 which has mean photon energy below the energy of absorption band edges of clad areas 11 and 13 impinges on a device semiconductor layer vertically. A modulated light signal 23 after exiting from the semiconductor device is used by an element 24. The average ring type contacts 20 and 21 are preferably provided so as to input and output the light signal to and from the semiconductor layer at right angles. The absorption of the signal 22 is proportional to the length by which it crosses an absorber. To effectively extend the absorption distance, the light signal entering the device semiconductor layer at right angles is reflected on the opposite side and crosses the absorber twice.  A light signal 32 which has mean photon energy hw and impinges areas 11 and 13 is modulated once, reflected by an electrode 30 through the absorber, and then projected as a modulated light signal 33 eventually. Consequently, while optical effect for modulation is obtained, high- speed operation can be done.

Title: Ink jet recorder
Inventor: YAMASHITA TOMIO
IPC: B41J2/18
Filed: 1990-03-05
Abstract: PURPOSE:To enable the title ink jet recorder to be miniaturized by decreasing space for arranging a suction port component by a method wherein each suction port component for sucking ink which in effected by following rotation is so constructed as to be capable of sticking fast to a discharge port surface of a recording head corresponding thereto. CONSTITUTION:When a carriage 3 moves from a recording area to an area adjacent thereto, a rack 7 starts meshing with a rotary gear 17. When the carriage 3 further moves, the rotary gear 17, i.e., a suction rotor 6 is rotated in the arrow A direction. By this rotation and movement of the carriage 3, a suction port component 61 comes first in contact with a discharge port surface of a recording head 21. By elasticity of rubber of which this suction port component consists, the suction port component sticks fast to the discharge port surface. Under this adhesion state, air in a suction chamber 60 is attracted with a pump 8, and ink in the discharge port of each recording head is attracted by negative pressure to be generated thereby. Then, the attracted ink is conducted to a waste ink tank 16 via a pipe 60 A. Consequently, at the discharge port of the recording head and its vicinity, a space for arranging the suction port component in order to perform discharge recovery process by sucking ink, and stuck water drop, etc., can be lessened.

Abstract: PURPOSE:To keep white balance, to suppress the generation of a color noise and to improve color saturation by detecting whether the color saturation is high or low and varying the relation between a video signal and the transmissivity of a liquid crystal panel. CONSTITUTION:The relation between the transmissivity of respective pixels of the liquid crystal display device and an RGB analog video signal are shown by using a T-V curve b102 when the color saturation is high or a T-V curve a101 when low. Then the 75% white part at the left end accords with the characteristics of the T-V curve a101, so the voltage level correspond to ACOL of 75% of AB/W and a display of TLCD=75% is obtained. A part from yellow to blue where the color saturation is high, however, accords with the characteristics of the T-V curve b102, so a luminance level of 75% is TLCD=100% at a voltage level of ACOL. Namely, the same display as before is obtained as to black-and-white parts of 75% white and 0% black, but the respective colors R, G, and B are improved in luminance by 25% from 75% to 100% as to the high-saturation part from yellow to the blue. Consequently, the color saturation of the display is considered to be improved.
