Title: Guidance line for transportation machine and formation of the line
Inventor: SASAKI YOSHINOBU
IPC: E01F9/518
Filed: 1994-04-18
Abstract: PURPOSE:To prevent a guide line from diffusively reflecting due to wet conditions during the rainy season and illumination at night, by forming a black powder layer having a large difference of brightness from the road face and a low brightness. CONSTITUTION:When a guidance line 1 for transportation machines, having a powder layer is formed on a concrete road face 4, At first, a two-liquid mixed type black resin paint 2 is applied on the concrete road face 4 by use of a line-drawing machine to make lines. Next immediately after application of paint, black rubber powder as a black powder layer 3 is scattered on the line 1. After 24 hours, the excess rubber powder which is not stuck to the line 1 is removed by use of a brush. In this way, the brightness of the surface of the line 1 is made greatly different from the road face 4 and the line is made of a black powder having a low brightness. Hence, diffused reflection due to the wet conditions during the rainy season and illumination at night can be prevented.

CONSTITUTION:The high alloy member such as maraging steel contg. 10% either of Cr or Ni and the mixture composed thereof is made to co-exist with the iron oxide. The above-mentioned co-existence is executed by heating the above-mentioned member in an oxidizing atmosphere to form the iron oxide film on at least part of the surface thereof, or in the case of the above- mentioned member having a small wall thickness of 0.1-5mm, by disposing said member and a member having the iron oxide film in proximity to each other at about 0.1-10mm distance. The member is then treated for about 10 min-4hr at 400-500 deg.C in the atmosphere essentially consisting of gaseous NH3 in the above-mentioned co-existence state. At least part of the surface part of the high alloy member is thereby nitrided.

Title: Rotating classifier for roller mill
Inventor: YOSHIDA HIROHISA
IPC: B02C15/00
Filed: 1995-04-04
Abstract: PURPOSE: To enlarge the area rate occupied by the width of a rotating blade on an upper section, increase the collision probability of particles carried by air flow with the blade on the upper section and provide the superior classifying characteristics by forming the blade width of the upper section of the rotating blade wider than that of a lower section. CONSTITUTION: In a rotating classifier for a roller mill, the blade width of an upper section of a rotating blade is formed wider than that of a lower section. What is important for the action and principle of the classifier is the action of a rotating blade upper classifying zone C. In the flow of particles in the rotating blade, rough grains move into the zone C with strong straight moving characteristics. The rough grains are more on the upper section of the rotating blade, and are concentrated on the zone C in the rotating blade. The action of zone C on the blade upper section, therefore, controls the rough grain classifying efficiency.  As the blade width of the upper section of the rotating blade is wider than that of the lower section, the area rate occupied by the width of the rotating blade is larger on the upper section in the circumferential direction to improve the collision probability of rough grains with the rotating blade remarkably than the rate heretofore available.

Filed: 1988-03-31
Abstract: PURPOSE:To improve orientation characteristic of a liquid crystal element with a simple method by constituting a liquid crystal element of a liquid crystal high molecular thin film having an orientation film oriented in one direction. CONSTITUTION:Liquid crystal high molecular thin films comprising orientation films 5, 6 having liquid crystals arranged thereon in one direction are formed on transparent electrode substrates 1, 2. When the liquid crystal high molecular thin films consist of a lyotropic liquid crystal high molecular compd., the thin film are produced by spreading a conc. liquid crystalline soln. to a thin layer on the substrates 1, 2 in one direction to form a thin film by evaporating a solvent. When the high molecular thin films consist of a thermotropic liquid crystal high molecular compd., the conc. liquid crystalline soln. is spread to a thin layer on the substrate 1, 2 in one direction at high temp. by elevating the temp. during film formation to >= transition temp., then forming a thin film by cooling the temp. to below the transition temp., thus causing orientation in one direction. By thin method, a liquid crystal element having superior orientation characteristic is prepd. conveniently.

IPC: A61J3/00
Filed: 1991-04-12
Abstract: PURPOSE: To prevent undesirable movement of a fluid by giving positive pressure to a storing chamber under evacutated pressure during movement of the fluid so that the fluid in a transfer line associated with pulsation of an upstream occluder is released. CONSTITUTION: A pressurizing means is a single pulsating pump and creates positive pressure or negative pressure in the chamber 18 during operation of apparatus in order to control ratio of liquid flowing in the chamber 18 or flowing out of the chamber 18. A controlling means 32 makes the pressurizing means generate positive pressure in a pressure conduit 26 fluid-communicating with the chamber 18 to increase fluid flow-out from the chamber 18 into a storing container 24 by a pressurizing means. Thereby positive pressure is given in the chamber 18 and when a second occluder means 30 is released in order to flow out the fluid from the chamber 18 to the storing container 24, the positive pressure makes the fluid flow out of the chamber 18 and enter the storing container 24. Thereby, reservation of the fluid in the chamber 18 is extremely reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a material feeding device by which miniaturization of an exposure device can be realized as a whole by suppressing generation of air bearing effect when a sensitive material is fed to a table in the exposure device and effectively using a dead space in the device. SOLUTION: A discharging roller 14h discharging a sensitive material 11 is set in the position higher than the upper face of a table 22.
