Title: Gun type burner device
Inventor: NISHIMURA SHIGEO
IPC: F23L13/04
Filed: 1993-12-27
Abstract: PURPOSE:To stabilize a flame holding operation of a gun type burner device during its minimum combustion state by a method wherein a supplying ratio between an amount of inner air to be supplied to a main flame combustion region through an inner air flow passage and a flame holding air volume supplied to the flame combustion region through a flame holding air passage is made variable. CONSTITUTION:A plurality of inner air valves 54 are formed at an upper part of a wall member of a main body 22a of an inner cylinder to cause an upper air chamber 41 to be communicated with an inner part of an inner cylinder 22, thereby an inner air passage 53 is constructed. In turn, a flame holding air valve hole 44 is constructed such that an upper air chamber 41 is cut and raised and communicated with an upper part within a main body 35 of a flame holding cylinder through a vane 32, thereby a flame holding air passage 45 is formed. An air volume distributing means makes a variable supplying ratio between an inner air volume supplied to a main flame combustion region through the inner air passage 53 and a flame holding air volume supplied to a flame holding combustion region through the flame holding air passage 45. That is, the air volume distributing means increases the ratio of flame holding air volume against the inner air volume from 1/3 to 1 as a combustion amount if decreased.

Title: Yarn winding method
Inventor: KAWABATA HIRAYUKI
IPC: B65H55/04
Filed: 1994-12-05
Abstract: PURPOSE: To eliminate throwaway yarn, and save yarn by alternately winding a dyed package and a package rewound once, and forming them into a single package. CONSTITUTION: For example, in a winding unit 1u where two kinds of packages Pa and Pb are alternately positioned in a paper feeding device 2 and standby positions 29 and 30, the yarn ends of these packages Pa and Pb are respectively connected to each other by yarn, and are continuously and completely wound, and are doffed as a single winding package Pw. In this way, since dyed yarn wound round the winding package Pw becomes yarn on which mutual darkly dyed parts of the dyed yarn and mutual lightly dyed parts are continued with each other, product cloth by knitting and weaving this dyed yarn does not cause a difference in a shade of color. Therefore, since there is no need to cut away the product cloth in a changing place of the yarn, throwaway yarn is eliminated, and the yarn can be reduced by its quantity.

Inventor: OGAMI HIROSHI
IPC: G03G15/04
Filed: 1988-12-27
Abstract: PURPOSE:To reduce surface fogging that developer adheres to an unnecessary part by providing such a gap that the developer does not contact with a recording body directly in a nonimage part between the recording body and a developing unit. CONSTITUTION:A developer carrier 27 carrying conductive magnetic toner 25 has a multipolar magnetic roller 32 where magnetic poles are made approximate and fixed on its inner circumferential surface inside a cylindrical developing sleeve 31 made of nonmagnetic material such as aluminum, etc., for example, which rotates in a direction shown by an arrow. In such a case, the gap between the developer carrier 27 and the recording paper 21 has such a distance that toner 25 on the developer carrier 27 does not contact with the recording paper 21 directly in the nonimage part. Thus, the surface fogging that the toner 25 adheres to the unnecessary part of the recording paper 21 is reduced and excellent development is performed.

Title: Steering device for skid steering vehicle
Inventor: NODA NOBORU
IPC: B62D7/14
Filed: 1987-12-28
Abstract: PURPOSE:To enable pivot turning to be smoothly carried out, when pivots are turned, by steering a vehicle so that the direction of wheels approach the actual proceeding direction of the vehicle. CONSTITUTION:When pivot turning in the right direction is carried out, the steering lever 25b on the left side is tilted forward, and the steering lever on the right side is tilted backward. Then, a limit switch 27bf and a limit switch 27ar are pushed by the extended parts 26a, 26b of trunnion levers 23a, 23b so as to be turned ON. A control box 28, receiving this ON signal, sends a control signal so as to change over the positions of control valves in a hydraulic circuit 29 so that wheels 4 can be brought into the pivot turning condition. As a result, the piston rods of all the hydraulic cylinders 21 are retracted to steer the front and rear, right and left wheels 4, so that the directions of the wheels 4 agree with the proceeding direction, thereby smooth pivot turning can be enabled.

Title: Unilateral step motor drive
Inventor: YOSHINO HIROBUMI
IPC: G03G15/041
Filed: 1989-12-20
Abstract: PURPOSE:To easily change an objective position by a method wherein a load is moved from a present position by a predetermined amount by a stepping motor pivoted into two ways and the difference of the number of pulses as well as the positive or negative value of the difference upon returning the load to the present position are detected to correct the present position. CONSTITUTION:A driven gear 14 is rotated by the driving gear 15 of a bilaterally rotatable stepping motor 16 to move a carriage 31, secured to an endless wire 11 extended between pulleys 12, 13, toward left-and-right. The carriage 31 is equipped with a lense 8, a photosensor 17 and a light shielding plate 18, for example, to detect the position of the carriage 31. When the carriage 31 is moved by a CPU, not shown in a diagram, by a predetermined amount in order to change the set magnifying power of the lense 8 and, thereafter, the carriage is returned to the present position, the number of pulses given to the stepping motor 16 is counted and a backlash is detected based on the difference of the numbers of pulses and the sign thereof whereby the amount of correction can be obtained. According to this method, the backlash may be detected and the positioning of the lense 8 to an objective position may be effected simultaneously, correctly and quickly.

IPC: G07D9/00
Filed: 1996-12-11
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a medium housing by providing a medium guide guiding the medium in the direction of separating from a notch part when the medium on a stage passes through the notch part in a second direction so as to avoid generating defective supply at the time of supplying the medium. SOLUTION: Even when a paper money 1 passes through a second output and input hole by moving in the direction of arrows A=B being the second direction of the stage 3 at the time of outputting money, the money on the stage 3 is brought into contact with a paper money guide 10 and passes through the second hole along the guide 10. Then the paper money 1 is not caught by the tip part of the second hole and moves with the moving of the stage 3. As the result, the paper money 1 is not folded to avoid generating defective supply when the paper money 1 is supplied out by a supplying roller 12, a paper feeding roller 13 and a separation roller 14. Thereby the reliability of the paper money housing is improved.
