Title: Fog-resistant resin
Inventor: SAKURAI SHINJIRO
IPC: C03C17/32
Filed: 1988-10-19
Abstract: PURPOSE:To obtain a fog-resistant resin providing fog resistance by coating the surfaces of glasses, plastic materials, etc., with it and being capable of keeping its effect for a long time by graft-polymerizing a specified vinyl monomer onto a water-soluble polymer. CONSTITUTION:A fog-resistant resin is prepd. by graft-polymerizing 0.1-10.0 pts.wt. vinyl monomer (A) wherein methyl (meth)acrylate and/or (meth) acrylonitrile are main components onto 1.0 pt.wt. water-soluble polymer (B) (e.g., wholly or partially saponified polyvinyl alcohol). The component B is a component holding the affinity to water and providing fog resistance, but has no water resistance, is soluble in water and has no durability. When the component A is grafted onto it, the grafted chains on the component B become hydrophobic and a colloidally water-dispersed resin is formed. While fog resistance is kept, the durability to water is not spoiled and if the surfaces of various molded items and films made of glasses, plastic materials, etc., are coated therewith, fog resistance is provided and the effect is durable for a long time.

Filed: 1985-11-22
Abstract: PURPOSE:To obtain an optical switch which switch numbers of input and output signals with low insertion loss and low crosstalk by switching light signals by utilizing the fact that the deflection direction of a light beam is controllable with the oscillation frequency of an acoustooptic element. CONSTITUTION:Light emitted by an input optical fiber 1 is converted by a lens 2 into a parallel beam, which enters the acoustooptic element 4. An acoustic wave is propagated in the acoustooptic element 4 by the vibration of a vibrator 6 to change the propagation direction of the light beam passing through the acoustooptic element 4. The (m)th input optical fiber 1 can be connected to an optional output optical fiber 8 by controlling the frequency of the vibrator 6 properly. Further, the light beam is made incident on the 2nd acoustooptic element 5 and the vibration frequency of the vibrator 6 is controlled by a vibra tion frequency control circuit 9 to make the propagation direction of the light beam coincident with the optical axis of an output optical fiber 8, thereby coupling the light beam with the output optical fiber 8 efficiently.

IPC: G11B7/26
Filed: 1987-10-19
Abstract: PURPOSE:To prevent the uncuring of the resin in the outermost circumferential part by introducing a gas for air discharge into a mold space and curing the photosetting resin by photoirradiation, thereby forming a substrate. CONSTITUTION:The air in the mold space formed of a quartz plate 1, an Ni stamper 3, an outside circumferential ring 5, a gas sealing ring 9 for air discharge, etc., is expelled through a gas discharge pipe 8 when gaseous N2 is admitted from a piping 6 into the above-mentioned mold space by opening a valve 7. The photosetting resin 10 is then injected from an injection nozzle into the mold space. The resin 10 is cured by the photoirradiation from a light source 12, by which the substrate for optical disks is formed. The oxidation of the resin 10 is prevented by the expulsion of the air and the uncuring of the resin in the outermost circumferential part by the oxidation is thus prevented.

Title: Control device for airconditioner
Inventor: ITOI YUICHI
IPC: F24F11/02
Filed: 1988-10-19
Abstract: PURPOSE:To make it possible to reduce the load of a microcomputer for outdoor equipment in terms of a multi-type airconditioner by providing to said outdoor equipment a synchronizing means which synchronizes the timing which starts the transmission of a signal to said outdoor equipment from each indoor equipment and a reader which reads the signals synchronously transmitted from each indoor equipment at one time. CONSTITUTION:A transmission and reception starting means 82 is transferred to an outdoor equipment side from an indoor equipment side so that signals transmitted from each room may be synchronized. To synchronize the signals, at first, the indoor equipment outputs a signal 91 which informs operation start to the outdoor equipment. Every time when the indoor equipment in a room A receives a signal from the outdoor equipment, it outputs a signal subsequently. When a transmission start signal is transmitted from a chamber B, the outdoor equipment does not respond with the signal immediately, but saves time which can meet the transmission and reception from the chamber A. A reception port is concentrated to the same input port 39 for exclusive use so that simultaneous reading from every chamber may be available. Therefore, the load of a program is substantially equivalent to that of one room.

Title: Method for diagnosing cause of process abnormality
Inventor: TEI KINGOU
IPC: G21C17/00
Filed: 1987-10-19
Abstract: PURPOSE:To diagnose the fault cause nodes independently of each other based on the abnormality pattern data after dividing those nodes into groups and to cope with contacts produced at one time by using a valid graph containing codes that defines plural measured points and non-measured points of a process as nodes. CONSTITUTION:The valid measured points are divided into groups excluding the invalid measured points showing no abnormality. The pattern of the non- measured points in each group is supposed as a valid measured point based on a valid flag containing codes. Then it is decided that the diagnosis of the relevant group is impossible in case such points corresponding to all valid measured points in the group with no conflict are available. When an invalid measured point showing no abnormality is detected, the corresponding pattern is supposed to count the detecting frequency of said invalid measured point and at the same time the subsequent transmissions of abnormality are neglected for discontinuation of the supposing process. In case an invalid measured point where the same abnormality patterns are supposed via >=2 groups is detected at the end of diagnosis, it is regarded that the connection is secured via said measured point and an inquiry is given to an operator.
