Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a half precast member by which it is possible to easily release an inner molding frame and at the same time, manufacturing the member without the necessity to depend upon centrifugal molding. SOLUTION: An inner molding frame 6 is diametrally expanded elastically until the diameter of the frame 6 equals the inner diameter of a half precast member to be manufactured by elongating a jack part 9 arranged in the inner molding frame 6. Next, concrete is poured and tamped into a gap between the diametrally expanded inner molding frame 6 and an outer molding frame 11, and after the concrete is cured, the jack part 9 is contracted to cause the diameter of the inner molding frame 6 to be reduced by elastic contraction. Consequently, the inner molding frame 6 is separated from the inner face of the poured concrete C and thereby is easily released.

Title: Preventive device for crack due to stress and corrosion of shrink fit wheel
Inventor: SENZAKI TOMOHARU
IPC: F01D11/02
Filed: 1983-05-04
Abstract: PURPOSE:To prevent a crack due to stress and corrosion of a key way by forming steam escaping holes to a diaphragm and a packing ring for a steam turbine and making wet steam escape to a stage on the downstream side. CONSTITUTION:Steam escaping holes 9a, 9b are formed to a diaphragm 6 and a packing ring 7 for a steam turbine. Since pressure difference among stages increases by the escaping holes 9a, 9b, wet steam 8a on the upstream side does not enter into a key way 5, and flows to the next stage through the escaping holes 9a, 9b. Even when a condensation 11 is generated in the key way 5, it is scattered to an outer circumference by centrifugal force, and discharged to the outside through the escaping holes 9a, 9b. Accordingly, a crack due to stress and corrosion of the key way 5 can be prevented.

Title: Pattern recognition system
Inventor: SHIMIZU HIROSHI
IPC: G06K9/68
Filed: 1985-04-12
Abstract: PURPOSE:To prevent recognition mistake due to mis-operation of the user by applying check discrimination with the maximum similarity decision with the full standard pattern, switching automatically the designation of partial group into a partial group decided by check discrimination when a contradiction between the discrimination result and the check discrimination is caused and it takes lace continuously as to an input pattern of a prescribed number of times and correcting the result into a category decided by the check discrimination newly. CONSTITUTION:The standard pattern is divided into the partial group depending on the font, the partial group is designated to apply matching. For example, if Katakana(square form Japanese syllabary) is kept writing in error while keeping the font as Kanji(Chinese character), the result of matching between the designated partial group and the entire standard pattern differs continuously and the result in the full standard pattern belongs all to the same partial group. In this case, the user considers that the designation of the partial group is in error, and the designation of the partial group is changed into the partial group to which the result of the full standard pattern belong so as to correct automatically the error in the partial group designation.
