Title: Gas-and-air mixing device for natural mixing type gas burner
Inventor: SUGIMOTO TAKIO
IPC: F23D14/48
Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To reduce length of a mixing pipe and at the same time attain high combustion heat valve in a device for mixing gas and air for a natural mixing type gas burner in which there are provided a nozzle having a gas injection port at its extremity end and a mixing pipe, air is automatically sucked with gas flow injected from the gas injection and both of them are mixed within the mixing pipe. SOLUTION: A shape of a gas injection port 24a of a nozzle 24 is formed into a flat slit shape. Due to this fact, a gas flow also forms a flat shape in its cross section, resulting in that a contact area between air around a gas flow and gas is increased and they are mixed rapidly. It is desirable that a shape of inner cross sectional surface of the mixing pipe 1 is formed into a short flat shape which is elongated in a longitudinal direction and a short size in a direction of thickness in correspondence with the shape of the gas injection port 24a.

Filed: 1985-10-28
Abstract: PURPOSE:To couple/uncouple an optical connector by single operation by forming a ferrule building the optical fiber in it, a supporting member, a fixture, and a coupling tool on a center axis. CONSTITUTION:The fixture 52 is located on a position for convering the point part of the ferrule 56 under non-coupled state, and when it is defined that force required for locking the fixture 52 on the coupling tool 61 at the time of coupling is f1 and force required for sliding the fixture 52 on the supporting member 51 is f2, the relation of f1<f2 is formed. Under the finally coupled state, the fixture 52 is located on a position where the fixture 52 does not cover the point part of the ferrule 56, and when it is defined that force required for removing the fixture 52 from the coupling tool 61 is f11 and force required for sliding the fixture 52 on the supporting member 51 is f22 at the time of uncoupling, the relation of f11>f22 is formed. Consequently, the optical fiber can be coupled and uncoupled by single operation.

Inventor: YAMADA RYOICHI
IPC: E02F9/12
Filed: 1986-10-14
Abstract: PURPOSE:To simplify the processing of inner gear to reduce the processing cost by a method in which the tooth shape of an inner gear for slewing wheel bearing is made into a straight tooth form, and the tooth shape of a small gear is made into one surrounded by involute curves. CONSTITUTION:The tooth shape of an inner gear 6 for slewing wheel bearing is made into a straight-line gear form, and the tooth shape of a small gear 9 is made into a shape surrounded by involute curves in such a way as to enable the teeth of the gear 6 to be simply processed and also to have a required turning transmitting performanc. The gear 6 is set on a slewing table 20 and cut by a serrated slice cutter 22 provided to a vertically movable main shaft head 21, and a chip 24 is attached to the body 23 of the cutter 22. In the case of the involute tooth shape, tooth shape changes as module and the number of teeth change. In the case of the straight-line tooth shape, the tooth shape is made constant when the inclined angle is mad uniform. Tools for swing circles of many kinds can thus be used in common and the processing cost can be reduced.

Abstract: PURPOSE:To decrease errors caused by a zero returning magnet and the like and to make it possible to perform highly accurate indication by differentiating the directions of magnetic fields which are generated with a plurality of coils from the direction of a magnetic field corresponding to the pointing direction to be obtained. CONSTITUTION:Driving signals such as currents and voltage are supplied to a cos A coil 4 and a sin A coil 5 by a sin A driving circuit 7 and a cos A driving circuit 8. Said driving signals have a phase difference corresponding to 90 deg. electric angle. The driving signals are changed in an AC mode with the characteristics based on sine waves and cosine waves with respect to an electric angle A. The electric angle A of the driving signals which are supplied to the coil 4 and the coil 5 advances in correspondence with the increase in quantities to be measures such as, e.g. vehicle speeds and engine speeds. The directions of magnetic fields generated with a plurality of the coils are made different from the direction of a synthesized magnetic field to be obtained with respect to the electric angle. Thus an error is generated with respect to indication which is to be obtained originally. Said error is synthesized with an error caused by, e.g. a zero returning magnet and the like. In this way, the pointing errors can be decreased.

Title: Color image forming device
Inventor: OGINO SHIGEO
IPC: G03G21/00
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To shorten image processing time when monochrome and color images coexist by changing image formation order, so as to shorten an image formation processing time, in the case that a coexistent mode is set and two sheets of paper can be held. SOLUTION: A transfer drum 12 has such a size that two A4-horizontal-size papers can be held (wound) by a chucking mechanism. It can be judged whether two papers are simultaneously held (double chucking) or not by the fact that the length of the paper is <= A4-horizontal-size or not. For instance, two A- and B-surface papers 18 and 19 are simultaneously held. When the monochrome image exists besides the color image, the monochrome and color images coexist and then, it is decided whether the double chucking is attained or not. When the double chucking is attained, a coexistent double chucking mode is set and when the double chucking is not attained, a single chucking mode is set. Thus, the contents of a printing job are confirmed and the image formation order is changed.

Filed: 1989-09-20
Abstract: PURPOSE:To ensure the stable working of a servo controller by using tentatively and sequentially the value obtained by subtracting the error command value from the target position value as the new target position value and securing the compliance properties to a control subject. CONSTITUTION:The error command value 11 is produced as a function of an estimated disturbance torque 9, and the value obtained by subtracting the value 11 from the target position value 5 is sequentially set as the tentative target position value 12. Thus a control subject 2 is provided with a function that secures the apparent compliance properties. As a result, the subject 2 is controlled with the compliance properties secured to an artificial disturbance load. Furthermore the subject 2 can be moved artificially even in an excited state. Thus it is possible to ensure the stable working of a servo controller with a slight force and with no use of a balance mechanism nor additional equipments like a force sensor, etc.
