Title: Independent performance test method for propeller
Inventor: NISHIYAMA SHIGEKI
IPC: B63B71/20
Filed: 1992-10-05
Abstract: PURPOSE:To allow easy determination of thrust and torque of propeller at high Reynolds number. CONSTITUTION:Propellers 10, 11 are arranged concentrically in the flow field at the test cylinder section 8 of a high flow rate water tank 1 and the propellers 10, 11 are rotated. Number of revolutions and flow-in speed corresponding to the advancing speed of the propellers 10, 11 are then imparted. A noncontact current meter 15 is disposed in the downstream of propeller between a position A separated from the propeller by a distance substantially equal to the diameter D of propeller and a position B separated from the propeller by substantially two times (2D) of the diameter of propeller in order to measure the axial speed in the downstream of propeller which is the sum of a flow-in speed V0 and an axial induction speed Wa, and an induction speed Wt in the rotational direction. Thrust and torque of the propellers 10, 11 are then determined highly accurately from the axial speed in the downstream of propeller and the induction speed Wt in the rotational direction thus measured according to a theoretical formula of momentum in which drag of propeller blade is corrected.

Title: Method of projection exposure
Inventor: HATTORI ATSUO
IPC: G03F1/76
Filed: 1988-11-17
Abstract: PURPOSE:To enlarge a focal depth while requiring only one exposure by changing position of a wafer along the optic axis during the exposure. CONSTITUTION:Optical pattern formed on a mask 14 is projected and exposed through a lens 16 onto a resist layer 12 on a semiconductor wafer 10. During said projection and exposure, the wafer 10 is first placed at a position Z1 on the optic axis and then placed at a position Z2 somewhat higher than Z1. In this instance, the wafer 10 is shifted continuously from the position Z1 to the position Z2 somewhat higher than Z1. The wafer 10 also may be shifted from Z1 to Z2 by multiple stages or reciprocally (in a vibrational manner). Focal depth can be enlarged thereby and hence production yield can be improved. Further., since only one exposure is required, throughput also can be improved.

Title: Magnetic head and its production
Inventor: TANAKA ISAO
IPC: G11B5/187
Filed: 1987-11-18
Abstract: PURPOSE:To improve a reproducing efficiency and to simplify a production process by coating a ferromagnetic thin metallic film having the film thickness of a gap butting face side larger than the film thickness of an opposite side to the gap butting face on the entirety of the sliding contact face of a medium. CONSTITUTION:Since the ferromagnetic thin metallic films 10a, 10b are coated on all the tape sliding contact face of magnetic core half bodies 7a, 7b, a boundary part between the core half bodies 7a, 7b and the thin films 10a, 10b is not formed on the tape sliding contact face but a pseudo gap by the boundary part is not generated. While the film thickness of the thin films 10a, 10b is formed to 40mum in the vicinity of an operating gap 11, it is thinner as it is separated from the gap 11. Since the ferromagnetic thin metallic film is not formed in a back gap side, an eddy current is not substantially generated in a high frequency area. The film thickness of the thin films 10a, 10b is constant irrespective of the width of a track, so that much time is not required for forming the thin films 10a, 10b in a magnetic head large in the width of the track.

Title: Magnetron
Inventor: OGURO TOMOKATSU
IPC: H01J23/213
Filed: 1992-10-29
Abstract: PURPOSE:To improve the separation of normal pi-mode from other types of mode and oscillation efficiency, and further improve the reliability of mass production by alternately arranging two sets of resonance cavities having different resonance frequencies around a tube shaft for constituting a cavity resonator group. CONSTITUTION:Every other gaps of root sections 3a of vanes 3 on the internal surface of an anode cylinder 2 are alternately made large and small, and the end sections 3b the vanes 3 are formed to have an equal gap from each other. Thus, a cavity resonator group is separated into a group A of resonance cavities 30, 32, 34, 36 and 38 having high resonance frequencies, and small dimensions and induced inductance, and a group B of resonance cavities 31, 33, 35, 37 and 39 having a low resonance frequency. Both groups A and B operate in push-pull type of mode at the time of a normal pi-mode vibration. In other types of modes, however, either A or B group falls in non-resonance state, and mode separation is improved. As a result, a strap ring does not need to be thick, and a microwave power loss is restrained, thereby enabling an oscillation efficiency drop to be prevented.

Title: Air-fuel ratio control method of engine
Inventor: UEDA KATSUNORI
IPC: F02D41/04
Filed: 1989-11-13
Abstract: PURPOSE:To execute a driving operation on an air-fuel ratio of a lean state without a misfire or a combustion fluctuation to improve the fuel consumption by controlling the air-fuel ratio so that the fuel becomes leaner than the stoichiometic air-fuel ratio when a running state automatic holding function, where a vehicle speed seldom varies, is operated. CONSTITUTION:An instruction to reduce a fuel injection quantity is output to a fuel control ECU 7 in accordance with a speed and load of an engine, the fuel injection quantity of an injector 3 is thereby reduced and the engine 1 is operated with an air-fuel mixture in which the fuel is leaner than the stoichiometric air-fuel ratio. The reduction ratio of the fuel injection quantity in this case is determined for each block which is formed by dividing engine speeds with loads into plural blocks and memorized in an automatic cruising ECU 8 as a map. In addition, when the fuel injection quantity is reduced, a throttle valve 2 is opened to increase the intake air quantity in order to maintain the specific vehicle speed. Consequently, when the automatic cruising is set and the engine speed with the load satisfies the lean condition, the engine 1 is operated with the air-fuel mixlture in the state of lean fuel.
