Abstract: PURPOSE:To prevent a propeller from being stolen by providing a lock means for selectively rotating a cam main body for releasing the engagement of a stopper and a nut. CONSTITUTION:In order to detach a propeller, a magnet key (lock means) 40 is fitted to the circular groove 33d of a cam main body 33 and its claw is fitted to a fitting part 33e. Then, a magnet in the key 40 is repulsed with a magnet in a lock main body 32 side arranged at the same position as it, the magnet of the lock main body 32 side is moved to a left side against a spring 37 force, slipped out of the circular groove 38 of the cam main body 33 side and the cam main body 33 can be freely rotated. Then, when the key 40 is rotated and the cam main body 33 is rotated by a required angle, the cam part 33b of the cam main body 33 retracts a stopper 35 horizontally and internally against the spring 36 force and releases the engagement of the stopper 35 and a lock nut 21. Thereafter, a cotter pin 23 is pulled, the lock nut 21 is loosened and the propeller is removed from a propeller shaft 11.

Filed: 1984-06-11
Abstract: PURPOSE:To use efficiently a memory by providing a means for selecting and controlling the case when both memories in a processor body or a memory module are used, and the case when only the memory in the memory module is used. CONSTITUTION:The case when only a memory of a memory module is used, or the case when both the memories of an information processor body and the module are used is instructed by a key input of a key input part.

Title: Recording and reproducing device and communicating method
Inventor: IKEDA KATSUMI
IPC: G11B15/02
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To improve reliability in reading and writing data in a nonvolatile memory when a tape which uses the nonvolatile memory is used. SOLUTION: When a tape is loaded, data in an MIC (internal memory) are read and the parity is checked (S10). When no error is found, the data are written to the memory (S11, S12). When an error is found, MIC contact restoring operation is performed by moving a cassette up and down (S15 to S17) and the parity is checked again (S10). The check and restoring operation are repeated and if an error is still found after restoring is repeated up to an upper- limit frequency (S14), the tape is fed to a ready position (S18) and the data in a system area on the tape are read in (S19). At this time, a flag in the system area which indicates which of MIC and tape system area data is used is so changed that the tape is used.

Title: Forming method for resin film on semiconductor substrate
Inventor: SASAKO MASARU
IPC: G03F7/16
Filed: 1979-09-20
Abstract: PURPOSE:To obtain a uniform resin film-thickness by applying photo resin to a semiconductor substrate before exposing it in an organic solvent atmosphere. CONSTITUTION:A semiconductor substrate is sent from a sender 9 to a spinner 10, which drops photo resin on the substrate rotating. Then the substrate is sent to a surface processor 11, in which an organic solvent is continuously injected from a nozzle to make an organic solvent atmosphere in the processor 11 provided with a cover. After this state is kept for a given time, the substrate is moved to an oven 12. This permits the step amount on the resin surface to be greatly reduced, and consequently its film thickness to be uniform, so that a micro pattern is readily formed.

Title: Wiring board
Inventor: KONDO HIROSHI
IPC: H05K1/11
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To protect joints against crackings caused by thermal stress, and to prevent a BGA(ball grid array) board from getting out of position due to a wiring wetted with solder. SOLUTION: Electrodes 12 arranged in a matrix form are smaller in diameter than the exposed parts 16 of a board, and wirings 15 are so formed as to be each possessed of a narrow part 14 in the exposed part 16 of the board. Therefore, solder melted and fixed to the electrode 12 is formed so as to wrap it up and does not cover a solder resist. Solder is hard to flow into the narrow part 14, so that a BGA board to be jointed hardly gets out of position due to the surface tension of the solder. Moreover, the narrow part 14 may be formed like parallel lines which are lessened in resistance, or a projection is provided to the electrode 12 in a direction opposed to the wiring 15 so as to cancel a tensile force caused by the surface tension of solder, which is conductive to enhancement in effect.

Title: Method and device for manufacturing butt welded steel tube
Inventor: KUROSAWA TOSHIYUKI
IPC: B23K20/14
Filed: 1988-05-18
Abstract: PURPOSE:To constrain the formation of the scale of an inner face by blowing air toward the external part of a tube from the inner face side of the pipe to the welding part which abutts both edge faces by forming a heated hoop in a tubular shape and blowing an inert gas or CO2 gas into the pipe. CONSTITUTION:The nozzle part 8 of an air blowing nozzle tube 7 is located near the welding part of a tube 18 inside to blow air toward an arrow mark A for the tube outer face from the pipe inner face. On the other hand the nozzle port 10 of an inert gas nozzle tube 9 is located inside the pipe 18 and an inert gas or CO2 gas is blown into the pipe for an arrow mark B. The temp. rise of the welding part is performed and the approach of the cooling water of a welding roll to the welding part is prevented as well. The generation of a scale on the pipe inner face can be prevented because the pipe 18 inside is filled up by an inert gas, etc. The scale loss of the pipe inner face is thus reduced and the welding defect by the cooling water of the welding roll can be prevented.

IPC: H01L31/04
Filed: 1994-06-03
Abstract: PURPOSE:To improve safety and reliability by a method wherein reactive power output from an inverter is detected, a phase-difference measured value based on the detection and a phase-difference command value transmitted over the inverter are compared, the single operation of the inverter after the generation of system service interruption is detected and the single operation is stopped. CONSTITUTION:The phase-difference measured value of output currents to reactive power, output voltage, actually output from an inverter 12 is computed by a single-operation decision circuit 22. On the other hand, a phase-difference command value transmitted over the inverter 12 is transmitted over the single- operation decision circuit 22 from a current control circuit 20. The single- operation decision circuit 22 compares the phase-difference measured value and the phase-difference command value, decides the inverter 12 as single operation when the absolute value of the difference of the phase-difference measured value and the phase-difference command value is larger than a tolerance, and stops the inverter 12. Accordingly, safety and reliability are improved.

Filed: 1985-06-04
Abstract: PURPOSE:To produce spherical low melting point alloy grains with a compact cooler by feeding a low melting point alloy in a particle state into the liquid in a heating zone to spheroidize the particles then solidifying the particles with the liquid in a cooling zone. CONSTITUTION:The high boiling liquid is preliminarily filled in a vertical pipe 2 and a liquid tank 1 and the upper part of the pipe 2 is heated by a heater 4 to form the heating zone A and the cooling zone B. The low melting point alloy is supplied to an injection nozzle 5 and is melted by a heater 6. The low melting point alloy is oscillated by an exciter 7 and is fed in the fine granular state into the liquid in the zone A. The pulverous particle alloy is spheroidized by the surface tension during descending in the heating liquid of the zone A. The spheroidal granular particles enter the cooling zone B where the particles solidify. The solidified particles accumulate in the tank 1 and the excess liquid overflows from an overflow pipe 8 according to the accumulation. The length of the cooling pass necessary for the solidification is thereby made shorter.
