Title: Polymer dispersion type liquid crystal display device
Inventor: IGARASHI TAKAHARU
IPC: G02B5/00
Filed: 1991-07-31
Abstract: PURPOSE:To miniaturize the display device constituted by combining a polymer dispersion type liquid crystal display element and louvers by reducing the thickness over the entire part thereof and to attain higher efficiency by eliminating the light loss by the reflection at the boundary between the liquid crystal display element and the louver member. CONSTITUTION:This display device is constituted of the liquid crystal display element constituted by interposing the louver parts 13a between counter electrode substrates 11 and 12 and packing a liquid crystal part 15 formed by microcapsulating a liquid crystal material and dispersing and holding the capsules into a polymer matrix into the spacings of the louver parts 13a and a rear surface light source body (EL lamp). The liquid crystals in the capsules array orderly in the parts impressed with an electric field. The liquid crystals array disorderly in the parts not impressed with the electric field. The light transmitted through the orderly arraying liquid crystal parts advances rectlinearly as it is. This light is absorbed on the wall surfaces of the louver parts and is admitted dark without emitting to the front surface side. The incident light scatters in the disorderly arraying liquid crystal parts and, therefore, the light which is not absorbed in the louver parts emits to the front surface side and is eventually admitted bright.

Title: Preparation of catalyst solution
Inventor: TANAKA YOSHIO
IPC: C08G63/86
Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To obtain a catalyst solution of high purity for polycondensation of polyethylene terephthalates by reacting antimony trioxide and acetic anhydride in the presence of a solvent, such as toluene, xylene or the like, to form antimony triacetate, adding a predetermined amount of ethylene glycol thereto or adding it to ethylene glycol, thereby preventing the hydrolysis of antimony triacetate. SOLUTION: The catalyst is prepared according to the reaction formula in a solvent. After the reaction, a calculated amount of ethylene glycol may be added to the reaction mixture, or the mixture may be added to ethylene glycol, without separating solid antimony triacetate. Subsequently, the solvent is removed in the form of an azeotropic distillate with ethylene glycol, and the resultant ethylene glycol solution of antimony triacetate is thermally insulated and delivered after encapsulation filled with dry nitrogen. All the steps are performed only by valve operations, so that antimony triacetate does not undergo hydrolysis. Toluene is used as a preferred solvent because of its low boiling point and the reduced content of ethylene glycol in the azeotropic mixture.

Abstract: PURPOSE: To ensure uniform drying by supplying particles to be dried into a cylinder together with hot air, and forming a spiral flow passage in the cylinder with a guide plate and a circulation adjusting plate. CONSTITUTION: A recirculation hole 7 is constructed between a casing 1 and guide plates 5, 6, and a circulation adjusting plate 8 is rotatably mounted on ends inside the casing 1 and the guide plate 5 for adjusting an opening of each recirculation hole 7, and a hot refrigerant inlet 9 and a hot refrigerant outlet 10 are formed in the casing and in both guide plates 5, 6. Once wet matter and hot air are supplied from an inlet cylinder 2 into the easing, these are violently mixed and form a turning flow from an outer peripheral side of the easing 1 in the central direction after passage through a flow passage 13, and they are discharged to the outside through an outlet cylinder 11 and an outlet cylinder 12.  Thereupon, when the circulation adjusting plate 8 is rotated to open the recirculation hole 7, solid matter with a large particle diameter moving along an outside wall surface of the flow passage 13 returns to the outside flow passage 13 from the recirculation hole 7 so that residence time, i.e., drying time is prolonged and hence uniform drying is realized.

Title: Tap position detector for on-load tap changing transformer
Inventor: AIKAWA KENICHI
IPC: H01F29/04
Filed: 1995-08-24
Abstract: PROBLEM TO BE SOLVED: To detect the tap position accurately at all times by prohibiting updating the detected tap position based on an output read out from a dial switch during a period when the operating time of an on-load tap changing transformer is being counted after receiving a tap up/down signal. SOLUTION: A tap position signal and a tap up/down signal 6 are read in from an LRT(on-load tap changing transformer) dial switch 3a. Presence of a main signal is then determined based on the tap up/down signal 6. When input of the tap up/down signal 6 is determined, updating the LRT tap position detection data is prohibited during a period preset in an arithmetic unit 5 and the detecting position is sustained in the previous state. Consequently, erroneous tap position detection output is surely prevented from being delivered during the tap change transient period of the LRT.
