Title: Fiber-reinforced plastic product
IPC: B29D23/00
Filed: 1993-01-18
Abstract: PURPOSE:To prevent defective molding and poor appearance from developing, improve dyeing properties so as to obtain more favorable appearance by a method wherein the product contains reinforcing fiber and nonwoven fabric layer employed outside the reinforcing fiber. CONSTITUTION:The product contains reinforcing fiber such as aramid fiber, carbon fiber, glass fiber or the like and nonwoven fabric layer made of glass fiber paper, carbon fiber paper, polyester nonwoven fabric or the like locating outside the reinforcing fiber. The product concerned is obtained by providing the nonwoven fabric layer between the reinforcing fiber and a mold when the product is subjected to reaction injection molding (RIM) under the condition that the reinforcing fiber is arranged in a mold or molded at normal temperature or elevated temperature by introducing mutually reactive monomers in the mold. As the resin used for RIM, polyurethane, polyamide and the like are exampled. By providing nonwoven fabric layer, the permeation of the reactive monomers for RIM in the fiber becomes easy, resulting in preventing defective molding and poor appearance from developing.

Title: Oxygen aeration of waste water
Inventor: MIURA MITSUGI
IPC: C02F3/26
Filed: 1981-01-14
Abstract: PURPOSE: To eliminate oxygen loss by a method wherein an impurity gas such as a carbon dioxide gas or the like in an aeration gas prepared by oxygen aeration is removed and, thereafter, oxygen is replenished in an amount corresponding to the removed gas amount to carry out recirculation aeration to enable constant high concn. oxygen aeration.

Title: Method of applying resist
Inventor: USHIJIMA MITSURU
IPC: B05D3/00
Filed: 1990-01-12
Abstract: PURPOSE:To form a resist film which can be exposed to obtain high-accurate uniform pattern width by applying light to which the resist is insensitive to the periphery, on which no semiconductor chip is formed, to measure film thickness when resist of the desired thickness is applied to the surface of a semiconductor wafer. CONSTITUTION:A light projector-receiver 8 to measure the reflection factor, refractive index, and thickness of a multilayer thin film 7 laminated on a wafer 1 is installed. The light projector-receiver 8 applies light as a beam b1 from a light source to the specified section 10 through the tip of an optical fiber 8, enters the reflected light b2 of the beam b1 through the tip of the optical fiber 9, converts it into an electric signal with a light receiving element, and measures the thickness of the thin film 7 by the light interference method. Since an excess region 17 is formed in the periphery 16 of the wafer 1, a detection part 10 is made there. Resist which is the pollution source of the wafer 1 and applied to the periphery 16 is removed from the flat detection part 10 on which no pattern is formed, therefore, the reflected light can be measured, while that on a semiconductor chip 15 having an uneven surface on which a pattern is formed cannot be measured because of irregular reflection.

Title: Image forming device
Inventor: YOSHINO KUNIHISA
IPC: G03G15/01
Filed: 1988-01-18
Abstract: PURPOSE:To form a desirable monochromic image without a setting bias independently at every developing means by performing monochromic mode development at a developing bias set by a setting means. CONSTITUTION:The combination of developing bias value corresponding to color specification is previously stored in a memory, and when a monochromic button is depressed, a CPU reads out the combination corresponding to specification made by a color specifying dial and inputs it to a control substrate. The substrate selects a developing device, determines a voltage impressed on a developing sleeve, and drives the developing device in receiving a timing signal. In a monochromic mode, the order of arranging developing devices determines the order of development. The arranging order of the developing devices 9Y, 9C, 9M, and 9BK is the order that maximizes reproducing ranges of B, G, and R in the monochromic mode. Thus, the monochromic image of color set by the color specifying dial is formed on a photosensitive drum 3 and the image is transferred and fixed on a transfer material P.

Title: Reducing valve
Inventor: HASEGAWA YOSHIHIKO
IPC: G05D16/02
Filed: 1987-01-13
Abstract: PURPOSE:To prevent chattering from being generated by decreasing a flow rate when a pressure reduction ratio is large and responsiveness from being lowered by increasing the flow rate when the pressure reduction ratio is small, by changing an aperture area almost in proportion to a pressure difference between pressure on a primary side and the pressure on a secondary side. CONSTITUTION:In the titled reducing valve, a flow rate adjusting valve 31 whose aperture area changes almost in proportion to the pressure difference between the primary side and the secondary side is provided at a path 17 which introduces a fluid boy on the primary side from a pilot valve 4 to a pressure room 7a on the upper part of a piston 7. When the pressure reduction ratio is large, it is assumed that the pressure on the secondary side is decreased less than set pressure from a state where the valve 4 is closed and a main valve 3 is also closed. Then, since a spring 6 overcomes the pressure on the lower plane of a diaphragm 5 and descends the diaphragm, the valve 4 is opened. Since a big difference between the primary side and the secondary side exists, a valve 34 is pressed to the valve seat side of a valve hole 33, and since the valve hole 33 is in a stopped state, the pressure fluid body is introduced to the pressure room 7a after the flow rate of the pressure fluid body on the primary side is limited. Therefore, it is possible to prevent a chattering phenomenon from being generated.
