Title: Production of optical cable
Inventor: SUGAWARA YASUYUKI
IPC: H01B13/02
Filed: 1980-10-22
Abstract: PURPOSE:To obviate the occurrence of breaking of optical fibers despite the exertion of tensile strain upon an optical cable by providing suitable slack to the optical fibers by using a hollow pipe-like material having rubber-like elasticity. CONSTITUTION:A hollow pipe-like material having rubber-like elasticity is used as a central member 12. First, internal pressure is beforehand applied to the central member 12 to keep its outside diameter expanded, on which optical fibers 14 are stranded and assembled to form a cable 10. Thereafter, the inside pressure is released to allow the member 12 to restore the original size, thereby creating the slack of the fibers 14 in the cable 10. With such constitution, the occurrence of breakage in the optical fibers is obviated despite the exertion of tensile upon the optical cable.

Abstract: PURPOSE:To obtain a display panel which has high density picture elements over a wide area by writing alternately signals which orient bistable ferroelectric liquid crystal of liquid crystal elements arrayed in plural rows and columns in two states at intervals of a scanning line in synchronism with the scanning signal, and controlling the continuance of the orientation states for each field. CONSTITUTION:The least significant, intermediate, and least significant digit bits of gradation data of respective picture elements A11-A44 are inputted to memories M1, M2, and M3 respectively. The data in the M1 is selected through a decoder DC and an MPX with a field switching signal and an AND gate is opened with a gate signal GT from a monostable multiplexer MM to use a clock signal CK as a row scanning signal F, thereby turning on drivers DR1-DR5 successively through a counter CNT. Data of respective rows of the M1 are writtenn in respective rows through drivers in an ON state among the DR1-DR5 together with the white signal obtained by inverting the black signal in synchronism with respective row scanning signals. A white signal is inverted in a next field to write the data from the M2. The data in the M1-M3 are displayed successively for a specific time for each field and a next frame is entered.

Title: Surface grinding machine for discarded confidential document
Inventor: FURUKURA KATSUMI
IPC: B24B7/20
Filed: 1990-06-08
Abstract: PURPOSE:To provide possibility of reuse of paper from destroyed documents, not only business sheets of paper but also thermosensitive paper, without involving black spots by furnishing a polishing wheel, on which a polishing sheet of sand paper, diamond abrasive grain paper, etc. is wrapped, and a polish receiving wheel consisting in a timber of Japanese cryptomeria, cypress, etc. or of a construction that such wooden material or any other material of a nature admitting grinding with the polishing sheet is applied to the surface. CONSTITUTION:With the front side facing up, each sheet of confidential documents to be destroyed is fed to between a polishing wheel 50 and a polish receiving wheel 51. Thus all surfaces of the documents are ground by a polishing sheet 52 wrapped on the polishing wheel 50, and when the sheets are sent to the opposite side, the all surfaces are thoroughly ground so as not to allow reading. The surface of this polish receiving wheel 51 consists of a material 56 (for ex., timber of Japanese cryptomeria, cypress, etc.) which admits grinding with the polishing sheet 52. Therefore, there is no risk that the part with paper fed solely decreases with the other portions ground, and because the surface of the polish receiving wheel 51 decreases uniformly, no level difference should be produced on the surface.

Then a data analysis part 10 is actuated and the original data is supplied from a text data storing part 9. Thus the forme processing is carried out in the area decided by an area producing part 8. In such a case, the part 10 refers to a pitch table 14 based on the style of type and the character code used presently for forme. Thus the pitch value of the corresponding character is obtained and the forme processing is carried out by this pitch value.

Title: Vertical deflecting unit
Inventor: YUDA MINORU
IPC: H04N3/16
Filed: 1978-12-06
Abstract: PURPOSE:To continue oscillation even if an operation level would vary greatly by sharing a capacitor between a time-constant circuit generating a saw-tooth wave determining an oscillation period and that generating a reference saw-tooth wave. CONSTITUTION:A constant-current circuit flowing discharging current I2 uses an emitter resistance for its transistor Q2 and can not flow current I2 without a voltage more than VCE of Q2. Here, when collector voltage VC of Q2 becomes higher than VL by reducing a vertical amplitude adjusting variable resistance while increasing the discharging current, the discharging level of capacitor C1 never reaches VL, so that since comparator circuit A1 can not obtain an inversion output, oscillation will stop. Here, a circuit where voltage VL is higher than the discharge stop voltage of capacitor C1 at any time such as Q10 is provided and because of VL1>VCQ2, circuit A1 is inverted to continue the oscillation. When current I2 increases, Q10 operates to equalize VL nearly to VL1 and the voltage increases togehter with I2, so that since VL1>VCQ2 is maintained, the stop of oscillation will never occur.

Title: Liquid crystal display device
Inventor: ADACHI KATSUMI
IPC: G02F1/1347
Filed: 1988-06-17
Abstract: PURPOSE:To obtain satisfactory hue by imparing different thicknesses to a 1st liquid crystal panel pinched between 1st and 2nd polarizing plates and a 2nd liquid crystal panel pinched between 2nd and 3rd polarizing plates. CONSTITUTION:The 1st liquid crystal panel pinched by a pair of transparent substrates 2 and 7 between the 1st and 2nd polarizing plates 1 and 8 is different from that pinched by a pair of transparent substrates 10 and 11 between the 2nd and 3rd polarizing plates 8 and 13 in terms of their thickness. As a result, a blue light source has a wide distribution of its wavlength and leaks green light most sensitive to eyes. The leaked light having wavelength passing through the 1st liquid crystal panel is shielded by the 2nd liquid crystal plate, thereby attaining deep black without leakage. Consequently, an image excellent in color reproducibility can be obtained.

Title: Probe for detecting flaw of pipe
Inventor: HIRATA KUNIO
IPC: G01M3/40
Filed: 1996-06-12
Abstract: PROBLEM TO BE SOLVED: To enable a probe to detect damage in pipes with reliability and accuracy by a simple operation. SOLUTION: A pin electrode 20 is inserted from the hole for checking pipe insertion of a joint, and the fitting recessed part 22c of a supporting body 22 is fitted onto the projected level part of a joint main body. When the fitting recessed part 22c is perfectly fitted onto the projected level part of the joint main body, the tip of the pin electrode 20 is stopped just before an inner insulating layer and in a state firmly on contact with a conductor layer. At this time, a corresponding electrode 21 also comes into a state on contact with the projection plane of the projected level part of the joint main body. In the case of the sticking of a nail on a pipe, the conductor layer consisting the pipe is in a conductive state with hot and cold water which fills the pipe via the nail.  So a limited resistance value according to the distance from a measured part to a damaged part is measured, damage and the location where damage occurs are detected.
