Title: Switching device
Inventor: KUDO TOSHIYUKI
IPC: H01H47/00
Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To restrict the generation of arc by opening a movable contact of a capacitor and a resistor first at the time of disconnecting operation, and absorbing the transient current to be a cause of the generation of arc with the capacitor and the resistor. SOLUTION: A movable contact 42a is formed to be disconnected first, and there is a possibility of an arc generation between the movable contact 42a and a fixed contact 41a at a moment when the circuit is disconnected. A capacitor 6 and a resistor 7, which are connected in series to each other, is connected in parallel with the movable contact 42a and the fixed contact 41a so as to absorb the transient and excessive current to be a cause of the generation of arc. Generation of arc can be restricted at the minimum by appropriately selecting the data of the capacitor 6 and the resistor 7. A control unit 5 controls a driving unit for separating the movable contacts 42a, 42b from the fixed contacts 41a, 41b, and as an easiest method, shape of cams is formed different from each other. With this structure, deterioration of the contact is prevented, and lifetime of a product is prolonged.

Title: Ignition control device for internal combustion engine
Inventor: WATANABE SATORU
IPC: F02D45/00
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To quickly interrupt current-carrying of a cylinder held in a current- carrying condition and avoid two-cylinder simultaneous current-carrying while quickly restart ignition control, by eliminating generation of backfire in an intake system after resetting to normality from cylinder discriminating abnormality. SOLUTION: A cylinder (#3), stopping ignition control when cylinder discrimination NG is judged and starting current-carrying in an ignition coil just before judging of NG, holds a current-carrying condition. After resetting to cylinder discrimination OK, the current-carrying hold cylinder (#3) interrupts current- carrying by the ignition timing of a back cylinder (#6) with a phase different from this cylinder by 360 deg. at a crank angle. Here, the intake valve open timing is delayed so as to prevent open starting of an intake valve of the cylinder (#3) interrupting current carrying. Thereafter, ignition control is restarted from a cylinder (#1) generating the regular current-carrying start timing.

Title: Rotary knife
Inventor: MATSUNAGA MOTOYUKI
IPC: B23D61/04
Filed: 1987-07-24
Abstract: PURPOSE:To maintain the good cutting quality of a cutting edge without any contact between the radial external face of the cutting edge and a workpiece, and without any re-polishing of the cutting edge by forming a recess open to a radial external side from the cutting edge of each cutter tip to the rear side thereof in the direction of chip thickness. CONSTITUTION:A chip 6 is brazed to a notch part 5 formed at the cutout part 2 of a plate 1, the external surface 7 of the chip 6 is formed to have a slope projected by an angle gamma with the tangential direction l of the external surface of the plate 1 and a corner part at the front 8 of the chip 6 in a rotational direction is polished, thereby forming a cutting edge 9. A V-shape recess 10 open to the external surface 7 is formed at a position backward of the cutting edge 9 in the rotational direction thereof, extending over the thickness of the chip 6. When the external surface 7 of the chip 6 wears and the cutting edge 6 becomes blunt due to cutting process, the external surface 7 nears a workpiece but the wear reaches the recess 10 before the external surface 7 comes in contact with the workpiece. As a result, the cutting edge 9 continues to maintain the cutting effect thereof and the cutting quality is maintained until the corner part of the back face of the recess 10 and the external surface 7 come in contact with the workpiece.

Title: Detector for abnormal wear of gear
Inventor: GOTOU HISAO
IPC: G01N3/56
Filed: 1980-12-26
Abstract: PURPOSE:To realize an early detection for an abnormal wear, by detecting the wear based on the difference of turbidity of the lubricating oil between the right- under part and the side part of the gear engagement within an oil tank. CONSTITUTION:The gears 2 and 3 engaging to each other are turned while being dipped into the lublicating oil in an oil tank 1. The turbidity of the lubricating oil is detected by sensors 3 and 4 for the right-under part and the side part of the engagement of these gears, respectively. The difference of these detection values is compared with the standard set value through a comparator 7. Then the output of comparison is displayed to a display device 8 via the comparator 7 when the difference of detection values becomes larger than the set value owing to the change of an operation time-lubricating oil turbidity curve which is caused by the abnormal wear of the gears 2 and 3. In such way, the abnormal wear is detected in an early period and assuredly.

Filed: 1987-07-24
Abstract: PURPOSE:To exactly measure the number of fine particles regardless of room temp. and to reduce the consumption of a solvent by enlarging the size of the fine particles of the mixed air cooled together with an air cooling chamber. CONSTITUTION:Laser light is focused by lenses 33, 34 by which the laser beam is applied to a measuring chamber 36 and is focused to the the upper part of a nozzle 21. The air in a mixing chamber 16 and a diffusion chamber 17 is sucked from a discharge duct 41 by a pump 43. The air for measurement is, therefore, guided into a high-temp. satd. steam chamber 2 via an inlet part 3. On the other hand, the air in the chamber is guided to the cooling chamber 8 and is controlled to a prescribed temp. The steam is the high-temp. satd. steam chamber 2 is, therefore, rapidly cooled and since the alcohol vapor deposited in the diffusion chamber 17 sticks to the fine particles of aerosol, the particle size of the fine particles is enlarged. The enlarged fine particles are ejected to a dust 41. Laser light is scattered when the fine particles passing through the focus of the laser beam and the scattered light is condensed 38, 29 and is converted 40 to electric signals. The number of the fine particles are displayed via a comparator and counter.
