Title: Ferroelectric liquid crystal element
Inventor: ISHIWATARI KAZUYA
IPC: G02F1/1343
Filed: 1989-03-03
Abstract: PURPOSE:To prevent a flaw from extending from a metal electrode end surface into a picture element and to improve the display quality by providing a step between an upper metal electrode part and a metal electrode part on the side of a transparent electrode. CONSTITUTION:Two metal electrode layers 1 and 2 are provided on the transparent electrode 3 of a ferroelectric liquid crystal panel whose one side is >=150mm long and the metal electrode layer 2 on the side of the transparent electrode has wide line width in a picture element direction from the upper electrode 1. Namely, metal electrodes on the transparent electrode 3 need specific film thickness because of the relation of resistance values, so the metal electrodes themselves are provided with a step. Consequently, even when a hairpin flaw part and a lightening defect part are generated, the metal electrode 2 on the side of the transparent electrode increases in line width toward the side of a picture element 6 more than the upper metal electrode 1, so the flaws are precluded to improve the display quality.

IPC: E02D5/58
Filed: 1995-03-09
Abstract: PURPOSE: To increase strength by tensioning axial reinforcements to provide specific prestress with high strength concrete and, at the same time, specifying difference between yield point or strength of the reinforcements and stress acting on the reinforcements with tensile force. CONSTITUTION: Tensile force is applied to axial reinforcements 2, and prestress less than 40kgf/cm<2> is provided to high strength concrete 5 formed by centrifugal force by means of a form 4. Then, the reinforcements 2 have difference more than 3000kgf/cm<2> between yield point or 0.2% strength and stress acting on the reinforcements 2 with tensile force. Then, even if bending load always works, prestress absorbs stress caused by bending load, and cracks can be prevented over an extended period of time. In order that the reinforcements 2 is made to reach the yield point or 0.2% strength, since stress more than 3000kgf/cm<2> is required to be applied to the stress, sufficient strength is obtained. By the constitution, cracks can be prevented, and axial force resistance and bending moment resistance can be increased to be stronger than even.

Abstract: PURPOSE:To improve the transmission quality by controlling an output/input ratio of a packet in accordance with the precedence of the packet and a combination of stagnations of a buffer. CONSTITUTION:The output frequency of a packet of buffers (2-1)-(2-4) is controlled by output permitting signals ACK(pr1)-(pr4) stored in a ROM 30 of an output control part.

When any of the stagnation signals Utr1-4 is not generated, and the signals Req(pr1-4) are generated, one of memory planes is selected, and the signal ACK is outputted. Subsequently, an address in the line direction in the memory plane is selected successively by a count value Q of the counter 4, and the signal ACK which is set to an address in its row direction is outputted. In such a way, both of immediateness and rejectiveness are satisfied and the transmission quality can be improved.

Abstract: PURPOSE:To prevent the adhesion of dust to a medium or an optical head by providing a tapestry weave-like filter in the outer peripheral part of the medium so that the medium is not brought into contact with the medium inside a cartridge case. CONSTITUTION:In the outer peripheral part of the optical disk medium 3 in the cartridge case 1, the tapestry weave-like air filter 2 is provided so that it is not brought into contact with the medium 3 with a guide plate 6.

It passes the filter 2 with a large action so as to be purified and the circulation 5 of air is formed. Thus, the adhesion of dust to the medium 3 and the optical head can be prevented, and since the filter is tapestry weave-like, the medium effectively operates even if in the case of reverse rotation.

Filed: 1992-03-09
Abstract: PURPOSE:To provide the interruption resetting packet communication system efficiently using a network by improving the possibility of transmission for a non-preferential transmitting packet while transferring a preferential transmitting packet within allowable oscillation delay time. CONSTITUTION:Respective communication nodes A-F store the number of communication waiting preferential transmitting packets (the number of succeeded preferential transmitting packets) at the time of starting current both-class communication mode for the transmission of high-class interruption reset and subtract that number from the number of succeeded preferential transmitting packets stored each time the preferential transmitting packet is transmitted in the current both-class communication mode and since the number is judged by using a parameter not to be added to the number of stored packets even when any preferential transmitting packet to be newly transmitted arrives at, the communication node residual time of the preferential transmitting packet can be suppressed within the allowable oscillation delay time.
