Title: Heat-exchange type blower
Inventor: YAMAMOTO TOSHIYOSHI
IPC: F28D11/02
Filed: 1981-10-01
Abstract: PURPOSE:To prevent mixing between two kinds of fluids running on both sides of a blade by inserting a cylindrical projection provided on a partition plate positioned toward the periphery of a peripheral plate holding the peripheral part of the blade into a ring-shaped groove provided on the peripheral plate. CONSTITUTION:When an impeller 1 is rotated, two different air streams 9 and 10 are generated on both sides of the impeller 1. Since there is a gap between the rotating impeller 1 and a fixed partition plate 4, air streams 9 and 10 on both sides of the impeller 1 are mixed to some extent when they are discharged to air ducts from the impeller 1. Therefore, a cylindrical projection 19 provided on a partition plate 4 positioned toward the periphery of a peripheral plate 14 holding the periphery of a blade 11 constructed of a corrugated thin plate into a ring-shaped groove 15 provided on the peripheral plate 14. This construction permits to keep the mixing between two kinds of fluids running on both sides of the impeller 1 at the minimum level.

Title: Method of sintering piezoelectric element
Inventor: TAKAHASHI JUICHI
IPC: H01L41/39
Filed: 1987-06-24
Abstract: PURPOSE: To prevent the change of a composition and the lowering of sintered density by holding a dummy element having the same composition as a molded element and thickness of one fifth or smaller of the molded element between the molded element having a PZT group composition and thickness of 1mm or more and a zirconia bottom plate.  
     CONSTITUTION: Two molded elements 1 having a PZT composition and thickness of 1mm or larger are superposed, zirconia bottom plates 2 are mounted to upper and lower sections one by one, and dummy elements 3 made up of the same elements as the molded elements 1 and having thickness of one fifth or smaller of the elements 1 are disposed among the elements and the bottom plates. The temperatures of the elements 1 are elevated to 1260°C from the normal temperature, and held for one hr and sintered. PbO is evaporated from the dummy elements during that time, the evaporation of PbO from the surfaces of the sintered elements is inhibited, and the diffusion reaction of materials of a different kind is not generated because the sintered elements and the dummy elements are brought into contact mutually. Since the thickness of the dummy elements is brought to one fifth or smaller, the molded elements are not overloaded. According to the constitution, the generation of cracks is prevented on sintering, thus improving the state of the surface.

Abstract: PURPOSE: To reduce the production cost of large-size molds etc. and lessen manpower by coating parting powder on the surface of a pattern provided in a metal flask and blowing a binder and aggregate then filling the metal flask inside with reinforcing sand and parting the mold.  
     CONSTITUTION: A pattern 1 is installed in a metal flask and a parting powder layer 2 is formed on the surface of said pattern 1. Thence, a liquid-form binder 3 contg. fine powder for coat such as silica sand powder and a binder such as phenolic resin is blown thence aggregate 4 such as silica sand is blown and is secured to the binder layer 3. Further, the liquid-form binder and aggregate are blown simultaneously or alternately, whereby laminar facing sand A of about 2W20mm thickness is formed and is thence hardened. Next, the space in the metal flask is filled with reinforcing sand and the pattern 1 is parted, whereby the mold is obtained. The formation of the facing sand is made easy by this method irrespective of the shape and position of the pattern 1. In addition, the laminar facing sand of high density and strength is obtainable; hence, the facing sand is made thin.

Title: Image display method of electro-optic device
Inventor: YAMAZAKI SHUNPEI
IPC: G02F1/133
Filed: 1991-05-31
Abstract: PURPOSE:To obtain a precise gradational display with suppressed influence of variance among elements by controlling the width of pulses when the pulses are applied to a liquid crystal material at such a period that the liquid crystal material does not respond. CONSTITUTION:When twisted nematic liquid crystal is used, for example, when the period of pulses is set to 1msec in a figure (a), a gradational display which is the brightest with A and brighter in the order of B, C, and D is displayed. The concrete principle is not known in detail yet. When, however, the pulses are applied to the liquid crystal material at the period in which the liquid crystal material does not respond, the width of the pulses is controlled to obtain intermediate density under digital control. The period of the pulses for obtaining the intermediate density like this is <=10msec in case of the twisted nematic liquid crystal. This control can be performed by connecting the output terminal of a deformed transfer circuit in which an N type and a P type thin film transistor act complementarily to a liquid crystal pixel electrode.
