Title: Fuel injection nozzle
Inventor: TORII SHINJI
IPC: F02M61/10
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To prevent the dispersion of product quality, and facilitate the accurate adjustment of damper characteristics by sufficiently checking the valve performance of a fuel injection nozzle. SOLUTION: An intermediate plate in which a recessed portion 41 containing pressure pin 7 so as to be free in sliding is arranged between a nozzle body 2 and a nozzle holder. In the recessed portion 41, a throttle portion 43 which overlaps with the outside wall 34 of the pressure pin 7 with a predetermined overlapping dimension L is formed, and an inner circumferential groove 44 and a notch groove 45 are formed on first spring chamber side than the throttle portion 43 so that a damper chamber 42 and the first spring chamber communicate with each other. Thereby, in the case where a needle 4 is moved to a seating side, when the lift amount of the needle 4 moves to the overlapping dimension L, bounce at the seating time of the needle 4 is reduced by a damper effect produced by the blocking of the damper chamber 42.

Title: Low flux leakage type magnetic circuit core
Inventor: KIZAWA MAKOTO
IPC: F02P7/00
Filed: 1989-01-18
Abstract: PURPOSE:To reduce leakage flux in a magnetic circuit having a plurality of gaps by covering the periphery of the gap with a magnetic body plate the thickness of which is made smaller so as to make the rate of area occupying in the gap section by far larger than the rate of the medium in the gap to the transmittance of a magnetic body. CONSTITUTION:An ignition device has a closed magnetic circuit consisting of a reluctor 5 having the same number of projections as the number of cylinders, a stator 6 and a permanent magnet 7. Magnetic resistance is varied by the change in the gap interval between the reluctor 5 and stator 6 and, in accordance with the change in flux density in the magnetic circuit, an ignition controlling voltage is generated from a pickup coil 8. In this case, in the pickup coil 8 in which a gap 2 is formed in a part of a core 1 on which a coil 4 is wound, the periphery of the gap is covered with a magnetic body plate 3 the thickness of which is made smaller so as to make the rate of area occupying in the gap section is by far larger than the rate of the medium in the gap 2 to the transmittance of the core 1, thereby reducing leakage flux.

Title: Positive plate for lead storage battery
Inventor: TAKAHASHI JIYUNJI
IPC: H01M4/62
Filed: 1982-01-20
Abstract: PURPOSE:To increase the initial performance and the life performance of a positive plate for a lead storage battery by adding an ion exchange resin having minute grain diameters to the active material. CONSTITUTION:The active material of a positive plate for a lead storage battery is added with an ion exchange resin having grain diameters within the range of 0.1-1mu. For instance, an anion exchange resin having SO4<2-> ions as exchange ions is made to be contained in the active material. As a result, when SO4<2-> ions existing around the electrode plate are consumed during the discharge, the electrode plate discharges SO4<2-> ions, which contribute to the discharge reaction and are exchanged for OH<-> ions. In contrast, during the charge, OH<-> ions are exchanged for SO4<2-> ions. By thus preventing any polarization which might be caused during the discharge, the initial performance of the battery is increased, and the life performance of the battery is increased.

Title: Method and device for sputtering
Inventor: TSUNEKAWA KOJI
IPC: C23C14/34
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To uniformize the distribution of the film thickness of a film deposited on a substrate, the distribution of the compositional ratios and the distribution of impurities in wide ranges even if the diameter of a target is controlled to the one equal to or below the diameter of the substrate by controlling the angle of the center axis line of the target fitted to a cathode to the normal of the substrate and the rotational speed of the substrate to specified ranges. SOLUTION: Preferably, the angle θ of the center axis line A of a target 3 of a diameter D fitted to a sputtering cathode 1 to the normal H of a substrate 2 of a diameter (d) is allowed to hold the relation of 15 deg.<=θ<=45 deg., the diameter D of the target 3 is allowed to satisfy d>=D to the diameter (d) of the substrate 2, and the rotational speed V of the substrate 2 is controlled to 4 to 60 rpm. Moreover, the distance F between the center O of the rotation in the substrate 2 and the intersection P between the center axis line A of the target 3 and the plane of the substrate 2 is controlled to 50 to 400 mm, and the distance L between the intersection P and the target 3 is controlled to 50 to 800 mm.  In this way, even if the diameter of the substrate 2 is made large, as to the target 3, film formation can be executed at a relatively small diameter with sufficiently high precision.

Title: Automatic detecter for water receiving tank water failure and wrong operation detecter for water receiving tank ball tap
Inventor: ITATSU TETSUYA
IPC: E03B11/00
Filed: 1995-01-23
Abstract: PURPOSE: To provide a device which can detect water failure before a water receiving tank becomes a droughty water state, in the case where water supply from a main pipe into the water receiving tank of a building is cut off by water failure, by detecting the above state and issuing an alarm to it. CONSTITUTION: When a water receiving tank is a water failure state, the float of a ball tap 5 descends to turn a motion detecting switch 11 attached to the ball tap 5 into a working condition. In addition, a water pressure sensor 10 informs the water failure state to a water supply control board 8. In the case where the ball tap 5 is in a working condition, and the water sensor 10 detects the water failure state, the water supply control board 8 indicates the information of water failure toward the outside. Thus, before a tank 1 becomes a droughty water state, an operator can understand to be the water failure state.

Title: Signal processing circuit
Inventor: NODA TAKAAKI
IPC: H03K5/1252
Filed: 1985-01-23
Abstract: PURPOSE:To eliminate noise without delay in signal detection by applying a pulse signal to a reset terminal and operating a counter circuit by a clock of a proper frequency to eliminate a pulse having a prescribed width or below as noise. CONSTITUTION:When the level of a dial pulse Pd applied to a reset terminal R of FF1-FF5 constituting a counter CNT changes from L to H, an output signal Pd' at an output terminal of the FF3 is changed to H, the counter CNT is reset while the level of the pulse Pd is at H and no count is executed. Thus, the counter CNT starts counting synchronously with a clock phic in 4kHz (period 0.25msec) and counts pulses up to 16 pulses, after 4msec (0.25msec X 16) is elapsed, the signal Pd' changes from H to L and the L level is maintained. The count is interrupted before the signal Pd' changes to L, and a high frequency noise having a width at least being <= 3.75msec is eliminated from the pulse Pd and malfunction is prevented.
