Title: Sprinkling nozzle
Inventor: TANABE TETSUO
IPC: B05B1/06
Filed: 1989-02-27
Abstract: PURPOSE:To obtain the sprinkling nozzle which decreases pulsation by longitudinally providing a water feed path in the lower part of the sprinkling nozzle body and communicating an inner cavity part and an outer cavity part via a water conduit diagonally provided in the water feed path. CONSTITUTION:The underground water arrives together with gases at a through- hole 9 from a water feed hole 2 when the underground water is fed into the nozzle from a water feed pipe 3. This water flows through a communicating hole 12 and the water conduit 14 to the inner cavity part 22 and is sprinkled from the inner cavity part 22 through a 1st sprinkling hole 24 to the outside. Even if the water flows from the inner cavity part 22 through the communicating path 23 to the outer cavity part 19, the resistance by the path 23 is large and, therefore, just a small volume of the water is discharged from a 2nd sprinkling port 27. The bubble-like gases flow through the path 23 into the outer cavity part 19 side at this time. The pulsation in ejection is prevented in this way and the free changing of the sprinkling direction is possible.

Title: Switching regulator
Inventor: WATANABE KAZUO
IPC: H02M3/28
Filed: 1991-03-12
Abstract: PURPOSE:To suppress a variation in output voltages even if a load current is increased. CONSTITUTION:In structures in which outputs of first, second rectifiers 2, 3 are output in parallel and in series and the outputs are separately output (load currents are substantially equal), a current transformer 5 is not bypassed by bypass diodes 6, 7, currents I1, I2 of secondary windings of a transformer 1b for power conversion are balanced, and variations in output voltages V01, V02 are suppressed to a predetermined value or less. If load currents of the first, second outputs are largely different in the case of independent outputs, primary and secondary side induced voltages V1, V2 of the transformer 5 become a forward drop voltage Vd or more of the diode, and are bypassed by the diodes 6, 7. As a result, it becomes the same as the case where no transformer 5 exists to prevent variations in the voltages V01, V02 of first, second smoothing circuits 2, 3 to a predetermined value or more through the transformer 5.

Title: Signal detection of reproducing magnetic head
Inventor: KATOU MASAAKI
IPC: G11B5/02
Filed: 1984-03-13
Abstract: PURPOSE:To reduce variation of an output voltage even if conductive dust is between an MR element and a shield, by flowing a current to a resistance formed with the magnetic shield so that the MR element and a part of the magnetic shield facing the MR element in parallel have the same potential and detecting a signal from the MR element. CONSTITUTION:A conductive magnetic shield 22 is formed to a shape approximately equal to that of an MR element 3 to have a resistance value. If conductive minute dust is stuck between the MR element 3 and the magnetic shield 22, a resistance 31 due to the magnetic shield 22 having a resistance value R2 is parallel with a resistance 11 of the MR element, and a voltage source 32 having a voltage approximately equal to V0=I0R0 is connected, and the voltage is so applied that a current is flowed in the same direction as the resistance 11 of the MR element. Though the resistance 11 of the MR element and the resistance 31 of the magnetic shield are connected with a resistance value R1 by a resistance 16 due to sticking of dust, corresponding parts of connected resistance 11 of the MR element and resistance 31 of the magnetic shield have the same potential. Thus, the current is hardly flowed, and the output voltage of an output terminal 15 is hardly affected.

Title: Vehicle speed measuring unit for vehicle speed controller
Inventor: SUGANO TOMOAKI
IPC: G01P3/489
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To provide vehicle speed measuring unit for constant speed traveling system in which the periodic data of vehicle speed can be obtained continuously with no interruption through a simple structure and an accurate speed can be obtained easily. SOLUTION: The vehicle speed measuring unit stores the periodic data 2 of vehicle speed pulse/sequentially at an arbitrary timing in a plurality of memory areas and operates a vehicle speed from each periodic data stored in each memory area. In this regard, the number of memory areas 5 is set larger, by at least the number of memory areas 5 being updated during operation of vehicle speed, than the number of pulse periods being employed during operation of vehicle speed. Since a vehicle speed is operated from the pulse periods stored in respective memory areas 5 which are not updated during operation of vehicle speed, the pulse period has no effect on the operation of vehicle speed even it is updated during operation of vehicle speed and no disablement nor correction of timer is required. Furthermore, the pulse period data 2 can be obtained with no interruption and thereby an accurate vehicle speed can be obtained.
