Title: Manufacture of semiconductor device
Inventor: OKUYAMA YASUSHI
IPC: H01L21/768
Filed: 1982-07-07
Abstract: PURPOSE:To form a stable inclination to a contact hole by applying an applying liquid for forming an SiO2 group coating, thermally treating the whole at a proper temperature, and obtaining an etching rate faster than an insulating film as a foundation. CONSTITUTION:The applying liquid (a silica film) 26 for forming the SiO2 group coating is applied to a sample, in which the photography of gate poly Si and the formation of source-drain are completed and to which a phosphorus glass film 25 is formed. The whole is thermally treated at a proper temperature. The etching rate of the film 26 through heat treatment in this manner is made faster than that of the film 25. When the contact hole is bored by a photo- resist and the surface is etched, a stable taper can be formed to the film 25 because the etching rate of the film 26 is faster. Accordingly, a disconnection in the contact section of an Al wiring can be prevented.

Title: Cash memory controller
Inventor: NISHIMURA HIROYUKI
IPC: G06F9/38
Filed: 1980-08-28
Abstract: PURPOSE:To increase the hit rate of cash, by processing in preference the data corresponding to an address of the reading request given from a CPU when said address coincides with the contents of an address buffer circuit. CONSTITUTION:Accepting the reading request of a certain instruction from a CPU1, a cash memory control circuit 20 for operand reads the data of a memory address supplied via a line 2 out of an operand cash memory 30 and supplies it to the CPU1. In case no reading request is outputted from the CPU1, the data supplied from a main storage device 4 stored in an operand data buffer circuit 50 is stored in the memory 30. When the memory address of the operand coincides with the data stored in an address buffer circuit 40, an operand coindidence detecting circuit 60 applies a coincidence signal to the circuit 20. Thus the circuit 20 processes in preference the request of storage from the circuit 40. The process to the memory 30 is also executed to an instruction cash memory 31.

Title: Dry-type transformer and installation structure thereof
Inventor: YASUDA TOSHICHIKA
IPC: H01F27/34
Filed: 1990-05-10
Abstract: PURPOSE:To improve a vibration-proof characteristic and reduce an installation space by a method wherein a coil axis is disposed in the transverse direction, a frame is provided on at least either side of the upper portion or the lower portion, a coil is fixed to the frame through an insulating material, and a ferrous core is supported through a vibration-proof device and without bringing it into contact with the coil. CONSTITUTION:When a ferrous core 1 is excited, a distortion corresponding to magnetic flux generates at the ferrous core 1, if a distortion rate in a rolling direction is 10, that in a right-angled direction is about 3. On the other hand, if a length of the ferrous core 1 in a rolling direction is 10, that in a right-angled direction is 0.5. Since, when the ferrous core 1 is excited on an alternating current, a magnetostriction is varied, the ferrous core 1 expands and contracts, and this expansion and contraction becomes an amplitude to produce a vibration, however an amount of distortion in a right-angled direction in a rolling direction becomes the order of 1/70. The ferrous core 1 does not come into contact with coils 2 and 3 and is supported by a pivot supporting device 7c, and since there is not anything restricting with respect to the expansion and contraction in a rolling direction, the vibration is not transmitted to a frame 5, namely a floor. Since the ferrous core 1 is suspended and supported through a vibration-proof rubber 7a in a vertical direction, the vibration is transmitted. However, a value in a vertical direction is small, and an apparent vibration transmitting rate becomes small.

SOLUTION: When large garbage such as a drifting log flows down, it collides with a coarse net 6, and its flow is blocked. The shock of the drifting log is not applied directly to a fixed bar screen 2 and is damped by the coarse net 6. When a large quantity of garbage is blocked by the coarse net 6, a net winding rope 23 is hoisted by a crane from the slightly upstream side than the fixed bar screen 2, the coarse net 6 is formed and lifted in a triangular shape on the side view together with the inclined bar screen 2 if there is no stream, and the garbage is lifted. When the lower pipe 9 of the coarse net 6 is lifted above a water intake path 1, the garbage is raked out with a fork.
