Title: Apparatus for charging molten metal in block type casting machine
Inventor: TAKAHASHI SHUZO
IPC: B22D11/06
Filed: 1987-03-27
Abstract: PURPOSE:To prevent breakage of end part of a nozzle caused by contact with block due to displacement of the nozzle, by dividing the charging refractory nozzle in iron shells into two, forming the end part thereof to tip exposed shape having small outer shape, and fitting semicircular cylinder type projection part, which are at right angle to line on upper and lower faces of upstream side, into grooves at inner face of the iron shell. CONSTITUTION:The refractory nozzle in the iron shells 14, 15, 17 for charging nozzle 6 arranging to a tundish 5 for a block type casting machine 2, is divided into two parts of a base part 9 and the end part 2. The outer shape of the end part 12 is smaller than the inner size of the iron shells 15, 17 and the tip is exposed from the iron shell 17. Further, the semicircular cylinder type projection parts 11, which are at right angle toward line direction on the upper and lower outer faces of upstream side, are arranged and fitted into the grooves at inner face of the iron shell 17. The refractory nozzle is afraid of the breakage caused by contacting with the block 1 due to displacement of the charging nozzle 6 because of thermal expansion, etc. of the tundish 5 but as the end part 12 is displaced, so as to make supporting point of the fitted semicircular cylinder shape projection part 11, the thermal shock is absorbed and the breakage of the charging nozzle is prevented.

Title: Cleaning method of face of mold for resin molding and brush member for cleaning
Inventor: OSADA MICHIO
IPC: B29C33/72
Filed: 1982-04-30
Abstract: PURPOSE:To perform scratching and stripping of a flash efficiently and shorten a cleaning operation significantly, by tapping the flash of a mold face continuously by the tip of the brush bristled mixedly with a fiber material and a wire. CONSTITUTION:The up-and-down motion of a hand brush member (A) is continuously done, aspirating the surrounding air out of the opening part 5 of a case. Holding this condition, the case (B) descends and a flash is continuously tapped in a vertical direction by the working tip of the hand brush member (A), then the tip of the wire scratches the flash. When the wire descends further, the tip of the wire is deformed elastically so as to slide on a mold face (C). Accordingly the tip of the wire infiltrates from the scratched part to the mold face (C) side after scratching the flash and strips the flash from the mold face (C) efficiently and forcibly.

The second semiconductor region 6 acts as a field plate without mediating an insulating film with respect to the first semiconductor region 3, and as a high resistance field plate that has greater concentrated field moderating effect than that of a conductive field plate. Accordingly, there is moderated concentrated electric field along the surrounding of the rectification barrier 10. Hereby, a high breakdown strength semiconductor device is assured with relatively greater effect of making breakdown strength of the device securely high.

Title: Leakage water detector for cooling water of plasma torch for heating melted steel in tundish
Inventor: SAIKI MASAKI
IPC: B22D41/015
Filed: 1991-04-08
Abstract: PURPOSE:To enable detection of even a small quantity of leakage water leaking from cooling water of a plasma torch for heating melted steel by carrying out operation of a flow rate difference value from a cooling water flow rate difference between this time and a certain time before, and making a judgment that water leakage is caused in the case when the difference exceeds an allowable value. CONSTITUTION:In the first leakage water judging means 7, cooling water flow rate difference operation 5 is carried out consecutively on flow rate differences from flow rate signals of both an inlet side flow meter 3 and an outlet side flow meter 4 in a cooling water passage 2 of a plasma torch 1, and in the case when the difference exceeds a predetermined allowable value A, a judgment is made that water leakage is caused. Furthermore, in the second leakage water judging means, the operation 5 is carried out on a flow rate difference value from the flow rate difference between this time and a certain time before from the time at which the former flow rate is generated, and in the case when the difference exceeds an allowable value B, a judgment is made that the water leakage is caused. Further, since the cooling water flow rate per a unit time can be regarded as constant, in the case when the water leakage is caused, apparent flow rate difference changes, and increases in proportion to the leakage water flow rate. Thereby, by carrying out operation on the flow rate difference value from the flow rate difference between the fixed time and the certain time before, and by comparing with the allowable value B, even a small quantity of leakage water can be detected.
