Title: Air cleaner
Inventor: KUTSUWADA TOKUICHI
IPC: E02B5/08
Filed: 1987-05-30
Abstract: PURPOSE:To house dust raked up into a hopper by turning a rake operating along a screen by a guide set on an apron. CONSTITUTION:A vertically movable rope 7 and an opening/closing rope 8 are connected to a rake 1 having a top roller and a base roller 3 to enable the rake 1 to vertically move by a drum 10. A guide arm 11 is also provided for the back side of a screen 4 in such a way as to permit it to turn on a supporting point 11a. Since the rake 1 ascending along the screen 4 and the apron 13 pushes up the arm 11 by complement of the roller 3 with a coupler 12, the rake 1 turns on the point 11a and is guided toward above the hopper 6, and dust 5 is thereby dropped and housed into the hopper 6.

Title: Winding method for metal strip
Inventor: TANAKA TSUKASA
IPC: B21C47/02
Filed: 1985-06-21
Abstract: PURPOSE:To reduce generation of cracks on a silicon steel sheet remarkably and to increase a yield by heating only the front end part of a strip above a specific temperature just before winding and winding the strip on a gripper type tension reel. CONSTITUTION:When a silicon steel sheet 3 containing 3% or more Si is wound on a gripper type tension reel 1, the front end part of the plate 3 is heated in a heating furnace 9 just before the winding. As for the front end part of the sheet 3 gripped by the reel 1, the temperature of about 1m length from the front end being equivalent to about 3/4 turn of the reel is kept above 100 deg.C; the temperature of the remainder is kept at 50-60 deg.C. The heating furnace 9 employs a heating means by a burner heating with town gas or be an induction heating. By this method, generation of cracks on the sheet 3 is preventable.

Title: Pneumatic radial tire
Inventor: TAWARA AKITOSHI
IPC: B60C9/08
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To accomplish the weight reduction of radial tire having sufficient case strength by constructing a core of a specific number of filaments and a sheath of a specific number of the same filaments in a steel cord excepting a wrap filament. SOLUTION: Excepting a wrap filament locking sheath filaments 3, a core is constructed of three steel filaments, each of which has a diameter of 0.2 mm or less and tensile strength of 400 kgf/mm<2> or more, while a sheath 4 is constructed of 8 steel filaments so as to reinforce a carcass. In this 3+8 structure cord in which clearances are provided between the sheath filaments 3, cord fracture is prevented when a great bending is inputted, so that deterioration of a cord life against fracture can be suppressed, and consequently, reduction in cord strength due to removal of the wrap filament can be suppressed without causing any deterioration in the card life against fracture. In this way, carcass strength of a branch new time can be lowered, and reduction in weight can be accomplished while durability is maintained.

Abstract: PURPOSE:To perform multiple-step combustion controls by a method wherein one or n motor-driven valves are additionally furnished on a combustion apparatus consisting of a booster pump, motor-driven valves, nozzle tips and others, and opened and closed. CONSTITUTION:Fuel pressurized by a booster pump 7 is blown from a low- combustion nozzle tip 1 via a main motor-driven valve 6 and a low combustion motor-driven valve 3 and burned. When the combustion rate is increased, a high-combustion motor-driven valve 4 and a return motor-driven valve 5 are opened at the same time, so that a portion of pressurized fuel is returned to a fuel tank via a return motor-driven valve 5 after passing through line main motor-driven valve 6 and a high-combustion motor-driven valve 4 and the rest is blown from a high-combustion nozzle tip 2 and burned. When the combustion rate is increased further, the return motor-driven valve 5 is closed and the total amount of fuel is blown from line high-combustion nozzle tip 2 via tire high-combustion motor-driven valve 4 and burned. Those actions are carried out corresponding to the load. Addition of a return motor-driven valve 5 enables four-step combustion rate controls and addition of n return-n motor-driven valves enables (n+3)-step combustion rate controls.

Filed: 1989-05-29
Abstract: PURPOSE:To eliminate the looseness of a screw between a coil and a head arm and to stably execute the positioning operation of a magnetic head by providing a bobbin, for which a notched part from an outside to a pickup hole is provided, between fitting holes. CONSTITUTION:A notched part 12 is provided in a central part in the inside of each fixed part 11 in a bobbin 6a and this notched part 12 reaches a pickup hole part 13a of the bobbin 6a.

Abstract: PURPOSE: To make automatic processig possible at the time of abnormal recovery by recording dummy data.  
     CONSTITUTION: To read control part 3, comparator circuit part 5 and dummy address recording part 7 are connected in sequence and between comparator circuit part 5 and dummy address memory part 7, write control part 4 is connected. As a result, when addresses fo address memory part 6 are updated, dummy data address memory part 7 is stored those updated addresses and write control part 4 refers to addresses in address memory part 6 by a write request signal from transmission- reception control part 8 to controller 2. In case that when transmitted data are written at a corresponding address position on floppy disk 1, the previous write position is lost due to the occurrence of abnormality such as power break, data read from floppy disk 1 by read control part 3 is compared by comparator circuit part 5 with dummy data in dummy data memory part 7. Then, addresses of write address part 6 are read out being updated until the both agree each other and the next process starts automatically from a coincidence point.

CONSTITUTION:The input of a digital signal is inputted to a compensating delay device 25 for the first and a signal on which a prescribed delay volume is given from a tap is sent out to signal lines l1, l2, m1 and m2. The inputs from l1 and l2 are outline-corrected respectively at a vertical outline correction FIR filter 21 and a horizontal outline correction FIR filter 22, and are synthesized at a synthesizing circuit 28a, and the inputs from signal lines m1 and m2 are respectively flare-corrected at a vertical flare correction compound 11R filter 23 and a horizontal flare correction compound 11R filter 24, and are synthesized at a synthesizing circuit 28b. The outputs are synthesized further at a synthesizing circuit 26 and is outputted as a correction signal. The delay volume is decided at the synthesizing circuits 28a, 28b and 26 so that all of the phases of the inputs are coincided, but because processes in a vertical and horizontal directions are executed in parallel, the corrections are not related with each other and a good correction can be obtained.

Abstract: PURPOSE:To reduce a non-linear error, and also to adjust a spot interval with high accuracy by synthesizing optically plural optical beams by using a diffraction grating, and adjusting the beam spot interval by changing an angle of the diffraction grating. CONSTITUTION:Optical beams B1, B2 emitted from laser light sources 11, 12 are made incident on a diffraction grating 9, and synthesized optically to a light whose optical axis is made to approach optionally, by the diffraction grating 9. Subsequently, the synthesized light is reflected by a polygon mirror 6 and projected to a photosensitive drum 8, but in that case, an interval of a beam spot is adjusted by driving an actuator 11 and changing an angle of the diffraction grating 9. In such a way, by using the diffraction grating, the optical axis can be made to approach optionally, and a non-linear error can be reduced. Also, the spot interval can be adjusted by only changing the angle of the diffraction grating 9, therefore, the spot interval can be adjusted with a high accuracy.
