Title: Electronic advancement ignition system
Inventor: KATADA HIROSHI
IPC: F02P3/045
Filed: 1978-06-23
Abstract: PURPOSE: To make the promotion of ensuring a spark performance and suppressing a power consumption, by such means that, ON-timing of the switching element be set to at a constant crank angle in a range below a certain rotational speed of the engine and advanced as the rotational speed increases in a range above a certain rotational speed of the engine.  
     CONSTITUTION: A comparator circuit 13 normally keeps a level of H for a rotational speed of the engine below a certain value, and a power transistor T 2  is turned ON at the time of -Q output of a flip flop 5 becoming OFF. And with a rotational speed of the engine coming to be above a certain speed, the comparator circuit 13 goes toward the level of L by a time corresponding to the speed, and the power transistor T 2  is turned ON at the time of becoming the level of L. Accordingly, the power transistor T 2  is turned ON at the time of the -Q output becoming the level of L, that is, at the position of maximum advancement angle determined by the position of a pulser 3, thus the timing of the transistor T 2  turning ON is advanced an angle as a rotatinal speed of the engine increases with a speed of the engine if exceeding a certain speed.

Abstract: PURPOSE:To enable to record in multiple colors on the back side of a recording paper, by a method wherein multicolor recording is conducted by sequentially superimposing unit images of different colors, a recording paper directed to the exterior of a circularly feeding passage is again introduced into the passage starting from the trailing end thereof, and is inverted. CONSTITUTION:The recording paper 4 on the face side of which multicolor recording is completed is discharged by a combined paper-supplying and paper-discharging roller 4, but the discharge is not completely performed, and when the passage of the paper 4 is detected by a sensor 15 for detecting the trailing end of the paper 4, the operation of the roller 14 is stopped, whereby the operation of discharging the paper 4 is stopped, and then the roller 14 is rotated reversely. At this moment, a reverse movement preventing plate 16 is driven to prevent the paper 4 from being moved reversely into a recording paper discharging passage 9. Therefore, the paper 4 is passed through a recording paper feeding passage 17, and is introduced into the circularly feeding passage 8 for the paper 4, starting from the trailing end thereof. The paper 4 introduced into the passage 8 is fed by a paper-feeding roller 5 and a press roller 6 with the back side thereof directed to the outside, and multicolor recording on the back side of the paper 4 is completed.

Title: Mounting of electronic component onto surface mounting substrate
Inventor: HOSAKA SHINICHI
IPC: H05K1/11
Filed: 1989-03-28
Abstract: PURPOSE:To surely solder an electronic component at a prescribed position without inducing a tombstone phenomenon by a method wherein a pad is provided so as not to protrude from the tips of electrodes in the lengthwise direction of the electronic component and formed wider than the electrode by some extent. CONSTITUTION:The outer ends of a pad 3 are made coincident with the tips of electrodes 1' and 1'' respectively and its width is larger than those of the electrodes 1 and 1' by 2mm, 1mm at each side. Therefore, solder does not attach to the outer ends of the pad 3 as the ends are coincident with the tips of the electrodes 1' and 1'', so that surface tension lifting up an electronic component chip is not induced, and on the other hand, as the pad 3 is wider than the electrodes 1 and 1', solder attaches to the margins of the pad 3 and then the electrodes 1' and 1'' are fixed to the pad 3. A width of 1mm is an optimal value that an electronic component does not migrate when solder is molten and enough bonding power can be obtained when solder is set. By this setup, an electronic component can be securely soldered at a prescribed position without inducing a tombstone phenomenon.

Title: Weather strip for automobile
IPC: B60R13/06
Filed: 1992-03-31
Abstract: PURPOSE:To bring the watertightness into full play even if a body shoulder part, where a drip lip is made contact close, is narrowed. CONSTITUTION:When a welt part 2 is attached to a flange part 20, an outward element 10 receives a pressing force out of a shoulder part 21 of this flange part 20. If so, an inward element 8 and the outward element 10 are bent so as to be vertically superposed in a bending part 9. In succession, the inward element 8 comes into contact with a projection 11. If so, a drip lip 7 is compressed in space between the projection 11 and the shoulder part 21. Therefore, the outward element 10 and the bending part 9 are made contact close to the flange part 20 and the shoulder part 21 in an elastic manner, thus water is preventable from penetrating into the welt part 2 from the outside of a car.
