IPC: F24C7/06
Filed: 1990-02-09
Abstract: PURPOSE:To prevent an accident by stopping the supply of a current in rapid response to the abnormal temp. rise in a main body case by connecting a heat conductive plate to the mounting plate mounting the bent part of a heater to the main body case and fixing a temp. excessive-rise preventing device thereto. CONSTITUTION:A U-shape heater 2 is provided to a main body case 1 and radiation fins 3 are provided to a straight pipe part 2b. Therefore, the surface temp. of a U-shape part 2a is higher than that of the straight pipe part 2b and, then, a heat conductive plate 10 having good heat conductivity is clamped to the heater mounting plate 9 fixing the heater bent part 2a to the main body case 1 and a temp. excessive-rise preventing device 11 is fixed thereto. By this constitution, the temp. of the heat conductive plate 10 suddenly rises at the time of the abnormal situation such that an exhaust port 8 is closed to stop the supply of a current to the heater 2. Therefore, an accident such as a burn or a fire can be prevented.

Title: Method for controlling stoppage to bucket of dump type carrier at fixed position
Inventor: HARADA AKIRA
IPC: G05D3/12
Filed: 1993-02-18
Abstract: PURPOSE:To accurately stop a carrier at a target stopping position by decelerating the carrier in the neighborhood of the target position, stopping the carrier when a bucket is detected by a photoelectric sensor, and performing dump-up by confirming the position of the bucket by an ID sensor finally. CONSTITUTION:The target stopping position of the carrier G is calculated by detecting the rocking angle of a cable crane main lanyard by an external computer. The carrier G is decelerated until the bucket is primarily detected by the photoelectric sensor 8a when the front end of the carrier arrives in the neighborhood of the target stopping position. The carrier G is stopped at a fixed position where a vessel 5 faces the bucket without being brought into contact with it when the bucket is secondarily detected by the photoelectric sensor 8b. It is decided whether or not the bucket is secondarily detected continuously by the photoelectric sensor 8b and also, the vessel 5 is detected by the ID sensor 6 i.e., a position is the target position by the external computer. In other words, the position of the bucket can be confirmed finally by the ID sensor 6, and the dump-up is performed by correcting the position of the carrier G when it is not the target stopping position. Thereby, accurate stopping can be performed.

Title: Semiconductor type pressure sensor
Inventor: MIURA SHIYUNJI
IPC: G01L9/00
Filed: 1982-02-25
Abstract: PURPOSE:To obtain a highly accurate pressure sensor not generating thermal stress, by sticking a circuit substrate to the one side of a supporting plate consisting of metal having a coefficient of thermal expansion resembled closely to that of a substrate material and sticking locally the other side to a bottom board. CONSTITUTION:A ceramic substrate 9 is joined by soldering etc. to a supporting plate 16 made of metal e.g. iron, nickel alloy having a coefficient of thermal expansion approximate to that of ceramics and also, this plate 16 is joined locally to the part near an opening 3 of a stem 2 e.g. only by a soft soldering layer. Hereby, on occasion of joining the substrate 9 to the plate 16, thermal stress is not generated because both coefficients of the thermal expansion are resembled and also, the thermal stress is not generated because there is a joining part at the time of joining the plate 16 with the stem 2. In this manner, a highly accurate pressure sensor is obtained.
