Title: Soldering method and soldering iron
Inventor: SHIMADA WATARU
IPC: B23K31/02
Filed: 1980-05-02
Abstract: PURPOSE: To reduce the quantity of molten solder that remains on the soldering iron in soldering process by using a nozzlelike soldering iron provided with a heater and an enclosure and blowing hot air to the molten solder at the joint.  
     CONSTITUTION: In soldering a wire 3 to a terminal board 4, a soldering iron 1 provided with a heater and an enclosure around the iron and shaped to a nozzle 9 is used, and soldering is made with molten solder 5. When the soldering iron 1 is pulled apart from the joint of the terminal board 4 and wire 3, high temperature air B heated by the heater in the nozzle 9 is blown to the molten solder 5 near the tip of the iron 1a to heat the solder. By this heating the viscosity and surface tension of the molten solder is lowered and the molten solder is perfectly separated from the tip of the soldering iron. Thus, the quantity of the solder at the joint is made uniform without excess and deficiency.

Title: Dust removing means for sweeping machine
Inventor: KAJIKAWA SABUROU
IPC: A47L9/10
Filed: 1978-05-17
Abstract: PURPOSE: To eliminate the fine dust throwing operation with a prefilter which should be handled manually for throwing dust out of a sweeping machine by adapting the valve of a fine dust pool to be opened by utilizing the force for rotating a dust dropping lever.  
     CONSTITUTION: When a dust dropping lever 9 is rotated, it produces rotating force and downward pushing force, and the latter pushes down a fine dust valve 28 to open a fine dust opening 29 for dropping down the fine dust from a fine dust pool 30. The dust dropping lever 9 transmits the vibration to a main filter 5 through a dust dropping spring 12 and a diaphragm 13, and the fine dust valve 28 receiving the vibration vibrates to drop the fine dust downward. Accordingly, before the dust is thrown out of the sweeping machine, the fine dust is transferred from the fine dust pool into the rough dust only by rotating the dust dropping lever 9, which eliminates the fine dust throwing operation with a prefilter which should be handled manually and achieves a clean dust throwing.

Title: Magnetic disk device
Inventor: MURAKAMI SATORU
IPC: G11B5/596
Filed: 1989-03-14
Abstract: PURPOSE:To always position a head in an accurate position by discriminating whether a data write operation is under work and performing a magnetic head positioning control based on a bit of position information read previously from a servo-pattern before the data write operation at the time of discriminating that the data write is under operation by an operation discriminating means. CONSTITUTION:Whether or not a magnetic disk control device is under the data write operation is discriminated by the operation discriminating means, and when it is discriminated by the operation discriminating means that the data write operation is under action, the positioning control on the magnetic heads 1-0 - 1-N is performed by a head positioning control means based on the position information read from the servo-pattern before the data write operation by a servo-head 2. Consequently, such a defect is eliminated that the head positioning is carried out into an inaccurate position due to an effect of cross talk of a magnetic field to be generated by a write current of the head during the data write operation. By this method, the head positioning control in the accurate position is always feasible, thus contriving high densification and promoted reliability of the magnetic disk device.
