Patent JP-S63234312-A (JP)
Title: Coordinate input device
Inventor: YOSHIMURA YUICHIRO
IPC: G06F3/041
Filed: 1987-03-24
Abstract: PURPOSE:To reduce the noises produced when vibrations are detected by providing a vibration preventing member at the peripheral part of a vibrating plate together with a part where said member is discontinuously changed and securing the interference among the reflected waves produced on the boundary surfaces. CONSTITUTION:A vibration preventing member 7 is attached at the peripheral part of a vibration transmitting plate 8 to prevent the vibrations transmitted from a pen from being reflected at said peripheral part and sent back to the center part of the plate 8. The member 7 has the width equal to an integer multiple of 1/2 wavelength lambda of a vibration transmitting wave on the surface of the plate 8. The elastic wave produced by the pen is first reflected on a 1st boundary surface K1 of the member 7 like a code D together with a 180 deg. phase shift. While the elastic wave component which is not reflected on the surface K1 is reflected on a 2nd boundary surface K2 at the edge of the plate 8 like a code E with no phase shift. Therefore, both reflected waves D and E interfere with each other and are canceled mutually. Thus, the reflected waves are extremely decreased.

Abstract: PURPOSE:To obtain a method for recording and reproducing a picture signal was not susceptible to the effect of picture quality deterioration even on the occurrence of an error through a transmission between a recording device and a reproducing device. CONSTITUTION:Error correction circuits 31, 32 of a picture signal reproducing device 30 receive respectively a reproduction signal 31i for usual reproduction and an auxiliary reproduction signal 32i for special reproduction and correct errors. A comparator circuit 35 compares an auxiliary coded signal 34s obtained from the reproduction signal 31i with an auxiliary coding signal 34s obtained from the auxiliary reproduction signal 32i and gives the result of comparison 35s to a correction circuit 33. The correction circuit 33 corrects a coded signal 31t outputted from the error correction circuit 31 only when a comparison result 35s from the comparator 35 indicates dissidence.

Title: Driving device of moving body
Inventor: OONO YUKIHIRO
IPC: G03B27/50
Filed: 1979-05-31
Abstract: PURPOSE: To eliminate the need for evacuating means of control member by directly providing protruding elements such as pins to an annular transmission body such as chain and actuating the control members for sheet feed mechanism, etc. by these protruding elements in the driving device of moving body such as an original platen and an optical system of an electrophotographic copier.  
     CONSTITUTION: A chain 23 is mounted with a moving body 24, a pin 26 for moving a bracket 25 and a pin 27 for actuating a control member 28. The pin 26 fits into the oblong hole 25a of the bracket 25. The directions of the pins 26, 27 differ with each other as shown in the sectional drawing A. Every time when the chain 23 makes one turn in the arrow direction, the moving body 24 moves reciprocatively linearly and the pin 27 actuates the control member 28 only once. Namely, the moving locus of the pin 27 for actuating the control member 28 differs in its height direction at the forward and backward movement of said pin owing to the chain loop, thus there is no need for evacuating means of the control member as in conventional devices.

Title: Guest host liquid crystal display element
Inventor: MASUDA HIROSHI
IPC: G02F1/137
Filed: 1980-05-23
Abstract: PURPOSE:To improve the contrast without darkening the display surface by subjecting pigment-added liquid crystal molecules to inclined longitudinal orientation and by placing a special wavelength plate and a reflecting plate on the back surface of a transparent electrode. CONSTITUTION:A nematic liquid crystal 14, having a negative dielectric anisotropy, to which a dichromatic pigment 15 was added is oriented longitudinally in an inclined form to be put between transparent elecdrodes 12, 17. A 1/4 wavelength plate 23 and a reflecting plate 20 are placed on the back of a glass substrate 18 supporting this transparent electrode 17. A light having an electric field vector crossed at right angles to the direction of the long axis of dichromatic pigment molecules at the incident time, when it is reflected at a reflecting plate 20 and returns to the liquid crystal, is rotated by pi/2, after changing to a light having an electric vector with the same direction as that of the long axis of a dichromatic pigment molecule, is absorbed to the dichromatic pigment. The light which does not contribute to the light absorption of the dichromatic pigment molecules goes out as it is as a reflected light. As a result, the contrast of the display is improved without darkening the display surface.

Title: Liquid drop separator
Inventor: ASAE MASAJI
IPC: B01J4/00
Filed: 1980-05-22
Abstract: PURPOSE:To prevent rescattering of liquid drops and improve separation efficiency by connecting a hollow porous tube to a liquid pool, filling liquid therein thence taking out the liquid stuck on the surface of the porous tube. CONSTITUTION:A hollow part is provided in a porous material to make a hollow porous tube 1, and this is connected at a head H to a liquid pool 3 by means of a conduit 2. Thence, the capillary adsorption force of the microcapillary tube in the porous material and the head H are maintaining balance, but when the liquid drops stick on the outside surface of the tube 1, the balance is broken and the liquid drops are sucked to the inner part by the force of the head H. Thence, the flow of the liquid 4 flows into the liquid pool 3 as much as it was sucked. Hence, the liquid can be taken out continuously, and the rescattering of the liquid drops does not occur.

Abstract: PURPOSE:To automatically set a control parameter for auto-repeat of a key in real time and in response to the using form of a user by adjusting the conditions of the auto-repeat of the key control in response to the key input device. CONSTITUTION:A duplication estimated character string memory 3 stores the character strings of the command which are frequently used. A character string comparison means 4 compares an inputted character string to be stored in a key buffer 2 with a character string to be stored in the memory 3. When the duplication of character strings is detected in the frequency higher than a prescribed level, the control parameter of a repeat parameter setting means 5 is changed. Then the time required for start of the repeat is extended or the repeating interval is shortened. Thus it is possible to automatically set the control parameter of the auto-repeat of the key in real time and in accordance with the using form of a user.
