Title: Plasma address display device
Inventor: HAYASHI MASAYASU
IPC: H01J17/04
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To facilitate the discharge of a plasma address display device, to suppress a discharge charge quantity and to make a life longer. SOLUTION: The plasma address display device has a laminated structure obtained by superposing display cells 1 and plasma cells 2. The display cells 1 are filled with liquid crystals 9 and have column-like signal electrodes Y. The plasma cells 2 are filled with discharge gas and have row-like discharge channels 5 parted from each other by partition walls 7. Discharge is induced by impressing sequential selection pulses to the electrodes formed in the respective discharge channels 5 to form charge particles, by which the linear sequential scanning of the respective discharge channels 5 is executed. On the other hand, image signals are impressed to the respective signal electrodes Y in synchronization with the linear sequential scanning to drive the liquid crystals 9, by which image display is carried out.  The partition walls 7 have openings 10 to communicate the adjacent front and rear discharge channels 5 with each other. The charge particles formed in the front discharge channels are introduced into the rear discharge channels 5s from the openings 10 to stabilize the rising of the discharge in the rear discharge channels. The charge particles diffused into the adjacent discharge channels acts as pilot fire, by which the rising of the next discharge is accelerated.

Title: Cement composition and its production
Inventor: DAIMON SEIKI
IPC: C04B22/00
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To obtain a cement composition capable of enabling chlorine bypass dust to be further effectively used without the reuse as a raw material for cement, having improved initial strength and hardly causing decrease of the strength with the passage of time by forming the composition out of each specific amount of a cement containing blast furnace slug and/or flyash, and the chlorine bypass dust. SOLUTION: The cement composition comprises 99.7-90 pts.wt. cement containing blast furnace slug and/or flyash, obtained by adding the blast furnace slug and/or the flyash to a blast furnace cement, a flyash cement of a Portland cement, and 0.3-10 pts.wt. chlorine by pass dust. Potassium chloride accounting for about 50wt.% in the chlorine bypass dust can improve and progress the initial strength of the cement composition. If the content of the chlorine bypass dust is lower than 0.3 pts.wt., the progressing effect is not manifested, and if the amount is higher than 10 pts.wt., the use of the concrete is limited because of high chlorine content.

Title: Ferroelectric high-polymer liquid crystal element
Inventor: TOSHIDA YOSHI
IPC: G02F1/1333
Filed: 1989-02-20
Abstract: PURPOSE:To prevent the deterioration in the orientability of a ferroelectric high- polymer liquid crystal arising from repetitive driving and the decrease of a contrast by crimping the ferroelectric high-polymer liquid crystal between substrates consisting of plastic films having >=200kg/cm<2> tensile strength. CONSTITUTION:The ferroelectric high-polymer liquid crystal element formed by crimping the ferroelectric high-polymer liquid crystal 2 between a pair of the substrates 1 and 1a having electrodes is so formed that the substrates 1, 1a consist of the plastic films having >=200kg/cm<2> tensile strength. Such plastic films the tensile strength of which is preferably >=300kg/cm<2> at ordinary room temp. are preferable for the substrates 1, 1a. At the time when the tensile strength is <200kg/cm<2>, the ferroelectric high-polymer liquid crystal element repeatedly receives the stresses generated by the electrostrictive effect at the time when the element is driven, by which a change is gradually generated in the substrate surfaces as well and the orientation of the ferroelectric high-polymer liquid crystal phase is eventually influenced. This influence appears as the deterioration in the orientability. The deterioration in the orientability of the ferroelectric high-polymer liquid crystal 2 arising from the repetitive driving is prevented in this way and the ferroelectric high-polymer liquid crystal element with which the decrease of the contrast is extremely little is obtd.

IPC: G06F15/16
Filed: 1984-02-29
Abstract: PURPOSE:To execute easily assignment without increasing hardware by constituting so that a processing element (PE) whose address has been determined sends address information to its adjacent PE, and the PE which has received it uses it as its own address. CONSTITUTION:A processing element whose processing element address generating flag 4 is logic ''1'' can determine its own address by itself, and a processing element whose processing element address generating flag 4 is logic ''0'' uses an address sent from other processing element, as its own address.

Abstract: PURPOSE:To obtain a magnetic recording medium having surface state of uniform and stabilized roughness by subjecting a substrate element to texture machining using an abrasive tape previously permeated with a slurry liquid of free abrasive grains uniformly over the entire width of the tape. CONSTITUTION:A disc-like substrate 1 is rotated in the direction A and a plurality of abrasive tapes, previously permeated with a slurry liquid of free abrasive grains uniformly over the entire width, are pressed to the opposite sides of the substrate 1 by means of a contact roller 3 and then the tapes 2 are run in the direction B thus polishing the substrate 1. Since the surface of the substrate 1 is subjected to texture machining under a state where free abrasive grains are permeated uniformly over the entire width of the tape 2, a magnetic recording medium excellent in stability is obtained in which average roughness is made uniform by lowering the height of maximum protrusion on the surface of the substrate.

Title: Mold structure for treating undercut in injection mold
Inventor: SAWADA MITSUO
IPC: B29C45/44
Filed: 1989-02-21
Abstract: PURPOSE:To obtain such a mold structure that a molded object is ejected straight forward at the time of ejection and a slant pin does not interfere with the molded object by providing an angle equal to the angle of the tip of the slant pin disposed along the inside of the molded object, at a support part of the other end of the pin. CONSTITUTION:A molded object 7 has an acute angular part at an upper surface thereof, and is provided with an undercut 11 in an inside surface part thereof. A cavity formed by a fixed-side mold plate 1 and a core 3 is filled with a molding resin. A slant pin 5 is guided relative to an ejector plate 4 by a retaining groove 6 having an angle beta greater than the slant angle alpha of the tip of the pin 5, and is ejected slantly while being guided by a guide groove 8 of the core 3. When the plate 4 is moved by a distance l, a tip part of the pin 5 is moved horizontally by (a). The distance L between the tip part of the pin 5 and the upper surface of the core 3 becomes equal to or smaller than l (L<=l) when alpha<=beta. Therefore, when the angle beta of the retaining groove 6 for the pin 5 is so set that alpha<=beta, the tip part of the pin 5 will not collide against the inner surface of the molded object 7, and the tip part will not interfere with the inner surface of the molded object 7. Thus, there is no possibility of defective molding, such as blushing and cracking.

Title: Electronic watch
Inventor: HASHIMOTO YUKIO
IPC: H03L7/00
Filed: 1978-04-04
Abstract: PURPOSE:To enable circuits to be stably operated even if the voltage of a battery decreases at the output generation of driving pulses by differing the time for performing digital frequency adjustment and the time when driving pulses generate. CONSTITUTION:A variable frequency divider 205 performs 5/8 frequency division when the output signal 206 of a data type flip-flop 204 is fixed at a low potential. If the signal phi12 207 is at a high potential when the signal 205 is outputted, the output of the variable frequency divider 205 becomes equivalently 6/8 frequency division as one pulse increases. If the signal phi12 207 is at a low potential, one pulse conversely decreases and the output becomes equivalently 4/8 frequecny division, thus the output is subjected to variable frequency division. As the time when the driving pulses are produced and the time when digital frequency adjustment is accomplished varies in this way, the circuits may be stably operated even if the battery voltage lowers at the output production of the driving pulses and the accuracy of the electronic watch may be enhanced.
