Title: Color filter
Inventor: TABAYASHI SEIICHI
IPC: G02B5/20
Filed: 1990-03-29
Abstract: PURPOSE:To obtain color filters without making delicate registration by regulating the width of colored printing images by projecting lines and injecting colored liquids without exceeding the height of the projecting lines. CONSTITUTION:The chromatic liquids r, g, b are respectively colored and injected into plural pieces of recessed parts 13 on a transparent substrate 11 segmented by the projecting lines 12 and are sealed by over coating layers 14. Namely, the chromatic liquids r, g, b are regulated in width by the spacing distance of the adjacent projecting lines 12 and, therefore, the chromatic liquids r, g, b are naturally regulated to a specified width and height within the respective recessed parts 13 if the projecting lines 12 are formed with desired accuracy. The superposing of the ends of adjacent printing images on each other and the generation of void-like defects arising from the generation of drop-out parts do not arise even if the registration is executed with not so much high accuracy at the time of the injection. The simultaneous formation of printing images of plural colors is possible in this way and the color filters are obtd. without making the delicate registration.

Title: Safety valve
Inventor: TERAI TOSHIO
IPC: F16K17/02
Filed: 1980-06-16
Abstract: PURPOSE: To release a working pressure securely to obtain a nonreturn state by a method wherein the working pressure is expanded in two stages during the detecting operations.  
     CONSTITUTION: When the pressure governing valve of a pressure cooker gets  trouble and the pressure reaches the working pressure of a safety valve, steam comes from a valve hole 5 into a chamber 13. Said steam pushes a seal 11 and is filled  quickly in the chamber 13 keeping a hermetic seal thereof. This pressure simultaneously breaks the balance with an energizing force F by a force corresponding to  the pressure on a diameter B and the valve body 9 rises. Then, the valve body 9  interrupts a parallel movement by means of a projection 7, is upset and does not  return to the original state.

Title: Prefoaming of expandable thermoplastic resin particles
Inventor: ANDOU MASAO
IPC: B29C44/34
Filed: 1982-05-14
Abstract: PURPOSE:To obtain thermoplastic resin prefoamed homogeneous particles having fine voids by a method wherein thermoplastic resin particles containing volatile foaming agent and inorganic nucleator are heated under a specified pressure and temperature and then discharged into a low pressure zone. CONSTITUTION:In a prefoaming method of thermoplastic resin wherein expandable thermoplastic resin particles containing volatile foaming agent dispersed in water is heated up to the resin softening temperature or more at the vapour pressure of the volatile foaming agent or more in a pressure resisting container and then the mixture of the above-mentioned particles and water is discharged to a low pressure zone, thermoplastic resin particles in which inorganic nucleate of 0.01-5pts.wt. are added to thermoplastic resin 100pts.wt. are used. When the addition quantity of inorganic neucleate does not exceed 0.01pts.wt., the desired homogeneous pulverization effect of voids can hardly be obtained and even though 5pts.wt. or more are added, a remarkable effect due to large quantity addition can not be available. Talc, potassium carbonate, alumina, barium sulfate, etc. are used as the inorganic nucleate.

Abstract: PURPOSE: To make best use of the advantages of soft welding and make joint strength more than equivalent to that of the materials to be welded by making the strength near the boundaries between the materials to be welded and deposited metal higher than that of the materials to be welded.  
     CONSTITUTION: A material of strength higher than that of the materials 1 to be welded is build-up-welded on the groove surfaces of the materials 1 to be welded and deposited metal 2' is constituted by a material of strength lower than that of the materials 1 to be welded by way of the build-up portion, whereby a weld zone 2 is formed. The groove is welded by a material of strength lower than that of the materials 1 to be welded, after which the weld heat affected zone is melted by high energy density beams such as electron beams or laser beams and is then frozen, whereby the reinforcing parts 3 made stronger than the materials 1 to be welded are formed. These result in that the fracture of the joint occurs in the portions to be welded sufficiently apart from the weld zone.

Title: Powder circulating fluidized bed reactor
Inventor: KUNITOMO KAZUYA
IPC: C21B13/00
Filed: 1991-04-15
Abstract: PURPOSE:To uniformly make powder flow throughout a fluidized bed to uniformly perform solid-gas reaction by forming projections of specific size in a specific place of a riser inside wall. CONSTITUTION:Projections that project about 1/20 to 1/5 of the inside diameter of a riser 4 forming a fluidized bed F are fitted all around the inside wall of the riser 4 in a place of 1/4 to 2/3 of the total length of the riser 4 from its top. Pulverized ore supplied from a feed supply port 1 forms the fluidized bed F by reducing gas introduced from below. The partly reduced ore is collected by a cyclone 5 and introduced from a downcomer 6 through a connecting pipe 8 to the lower part of the riser 4 by circulation. The pulverized ore from the fluidized bed F is made to flow in the riser 4 by reducing gas blown up, but the ore once raised falls along the surrounding inside wall to stay temporarily nearby the projections 9. The ore thus stayed is moved in the central direction by the projections 9 and fluidized again by reducing gas blown up hard in the central part to improve reaction efficiency.

Filed: 1994-04-21
Abstract: PURPOSE:To correct color slurring at a non-focused part by inputting an image with high fidelity concerning the image input method for inputting a three- dimensional object as a two-dimensional image. CONSTITUTION:First of all, the distance image and color image of the three- dimensional object as an image pickup object are possessed by a range sensor, optical system and image pickup system (Sl). Next, the position of the distance image is corrected from the arrangement of the range sensor and the lens of the optical system, and it is arranged at the same position as the color image (S2). Afterwards, the deviation of all the picture elements in red, green and blue is calculated according to the resolution of the color image or the distance image and the value of the distance image (S3), and the picture elements at positions deviated just for the respective calculated deviation components are pulled out and synthesized for each of picture elements in red, green and blue (S4). Finally, the color image is outputted (S5). Thus, the deviation of picked-up picture elements caused by the difference of positions from the optical and image pickup systems caused by the three-dimensional shape is corrected, and the color image can be inputted with no color slurring.
