Title: Noncooling type smelt spout
Inventor: TAKITA KATSUHIKO
IPC: F23J1/08
Filed: 1992-10-16
Abstract: PURPOSE:To prevent a smelt from corroding by fitting a tip ceramic block into slopes of specific protrusions provided in the tip of a smelt spout made of a highly corrosion-resistant alloy. CONSTITUTION:Protrusions 14 having slopes (2b) on the sides thereof are formed in the tip of a smelt spout, having the inner surface coated with a ceramic block and made of a highly corrosion-resistant alloy. The tip ceramic block 11 having slopes (2a) in a form fitted into the slopes of the protrusions is fitted into the protrusions. Thereby, the ceramic block can be prevented from breaking and the smelt can be prevented from falling off in the flow direction even if the breakage occurs. As a result, the body made of the highly corrosion- resistant alloy such as high-Cr alloy can be prevented from corroding.

Inventor: ISOZAKI TSUNEAKI
IPC: H01L27/04
Filed: 1988-11-02
Abstract: PURPOSE:To eliminate the formation of an unnecessary groove on the periphery of a substrate even if a deep groove is formed by etching, and to prevent a film from increasing on the periphery of the substrate of a photoresist coating film generated in a next step by altering a photoresist film removing amount of the periphery of the substrate in each step of photolithography. CONSTITUTION:After an SiO2 film 2, an Si3N4 film 3 and a photoresist film 4 are sequentially formed on a silicon wafer, the film 4 approx. 5mm inside from the periphery is removed. Then, the pattern of an inner element is formed, the film 3 is etched, the film 4 is removed, and an element isolating thick SiO2 film 5 is formed by selective oxidation. Then, the film 3 is removed, it is coated with a resist film, and approx. 3mm from the periphery is removed. Thereafter, a patter for forming a groove is formed, and the film 2 and then the wafer 1 are etched. In this case, when the conditions are so set as to reduce the etching amount of the SiO2 film, a groove is not formed on a region 7 due to the thick film 5, and even if it is coated with resist in a next step, the thick film is not formed on the periphery of the wafer 1.

Abstract: PURPOSE:To form simply and easily etching resistance silicon nitride film and to flatten a dielectric isolation type semiconductor device by forming a groove in the end of an isolating oxide film exposed on the face of a substrate, and then filling the groove with the silicon film by utilizing etchback technique. CONSTITUTION:Only the end of an isolating oxide film 15 exposed on the face 19 of a base substrate is selectively removed by etching to form an opening on the face 19, and a groove 31 is disposed. Then, a silicon nitride film 33 is deposited approx. 7000-1000(Angstrom ) thick at the upper side of a substrate 21 by a CVD method. Then, after PSG is deposited approx. 10000(Angstrom ) at the upper side of the film 33 by a CVD method, it reflows. After this step, it is etched back to the face 19 by etching technique capable of substantially equalizing the removing speed of the PSG used for eliminating a recess to that of the silicon nitride, and the film 33 remains only in the groove 31.

Abstract: PURPOSE:To generate a test pattern signal not to cause the competition of a bus control at the time of generating the test pattern signal of a logical circuit including a bus by providing a bus extracting means, a bus control means and a test pattern preparing means. CONSTITUTION:In the test pattern signal generation of a logical circuit including a bus, a bus extracting means 4 extracts the bus after a first test pattern preparation executed by paying attention to a certain trouble while the input value of a control gate is not determined, and outputs the bus control information to a bus control means 5. The means 5 determines the input value of the control gate so as to make only one bus control effective in accordance with the bus control information. A test pattern preparing means 2, when the control gate input value of the bus is not determined, assigns the defined value to one of the control gate input values of the bus, assigns a high impedance value to others, executes the backward pursuit, and prepares a partial test pattern 7 which is a third test pattern. As needed, by the output of a second test pattern 9, the test pattern signal not to cause the competition of the bus control can be prepared.

Filed: 1998-10-01
Abstract: PROBLEM TO BE SOLVED: To prevent the oscillation and overturning of baggages by the tilt motion by providing a link body journalled to a point of a first arm as a point of application of a parallel link, and a point of a second arm as a point of application of a parallel link to a point on a supporting base. SOLUTION: The total weight of a link body 13, a loading plate 29 and the baggages placed on the loading plate acts as the force in the direction to rotate a pin 17 clockwise on a pin 12. When a lift cylinder 20 is contracted, an auxiliary link 16 is slightly rotated anticlockwise on a pin 18. The pin 15 is rotate anticlockwise on the pin 18. The pin 17 is rotated clockwise on the pin 12, and the loading space 29 is tilted to lower its point. The tilt motion is executed at an approximately AB/AC rotating distance to the contraction of the lift cylinder 20 at an approximately constant speed. Accordingly the loading space 29 is slowly inclined at a constant speed.

Title: Mold apparatus
Inventor: ENDO MASAMI
IPC: B29C45/34
Filed: 1986-11-25
Abstract: PURPOSE:To carry out a complete degassing from a part where a hollow projection should be molded and to make it easier to repair a part where a hole of the projection is molded, by inserting a core pin being served as a gas vent on one of the two molds, and forming a hole by contacting the apex part with another mold. CONSTITUTION:A groove 25 having a slope 25a is formed on one side face of an apex part of a projecting mold 19 and a projection part 24 is tightly inserted in the groove 25. A hole 4 is formed in a hollow projection 3 by contacting the projection part 24 with the groove 25. A movable mold 12 is fitted to a fixed mold 11 and a molten resin is supplied in a cavity C. While the molten resin flows into the cavity, the gas in the cavity flows through a small gap existing between a core pin 20 and the movable mold 12 in the direction shown with an arrow mark 28 and is evacuated outside through a gap between a fixed plate 13 and a movable diaplate 14. The molten resin is accordingly applied into the cavity C. Since the projection part 24 of the core pin 20 is inserted in and contacted with the groove 25 of the projecting mold 19, the resin can not flow into the part and a hollow projection 3 having a hole 4 on its side can be thereby molded.

Abstract: PURPOSE:To improve the efficiency of a system test by executing a recognition to all slots, and transmitting all of its results to an external information processor through a shelf interface and an external interface. CONSTITUTION:When an external information processor 1 designates a rack train and a rack number with respect to a rack to which it is desired to know mounting information, an on-rack mounting recognizing circuit 2 of the corresponding rack discriminates a fact that its circuit itself is designated, and sends out the contents of a self-display circuit to an external interface. When the mounting information related to an n-th shelf in the own rack is requested from the external information processor 1, an in-shelf mounting recognizing circuit in the corresponding position sends back the contents of the self-display circuit. Also, in the case the external information processor 1 requests mounting information of a package with regard to a specific shelf in a specific rack, its instruction is accessed in order of all mounting slots, and a classification of a mounting package is recognized.
