Title: Two-stage type water jet type jet propulsion ship
Inventor: ISHIKAWA AKIRA
IPC: B63H11/103
Filed: 1993-09-30
Abstract: PURPOSE:To reduce fuel consumption, a ship hull weight, and a cost by a method wherein an obliquely frontward downward protrusible and retractable moving scoop member is arranged to the bottom of the rear end part of the front intake of an upper duct, the scoop member is contained in the bottom during low speed sailing, and the scoop member is protruded during high speed sailing. CONSTITUTION:When a ship is staticized, a moving scoop member 8 inserted in a bottom part in the vicinity of the rear end of the front intake 6-1 of an upper water jet pump 3-1 is protrusible by a hydraulic cylinder 9. The protrusion causes easy guidance of a water flow along a bottom 7 through a front intake 6-1 to an upper duct 5-1. During low speed sailing by thrust of a lower water jet 3-2 positioned under a water surface when the ship is staticized, water is feedable to the upper water jet pump 3-1. As a result, high thrust is generated at further low speed. Further, after the upper water jet pump 3-1 is operated, the hydraulic cylinder 9 is pulled to its original position and the scoop member 8 is contained in a ship and this way reduces the occurrence of ship hull resistance during high speed sailing.

Title: Method for driving stepping motor
Inventor: KASAHARA RYOJI
IPC: H02P8/00
Filed: 1995-10-17
Abstract: PROBLEM TO BE SOLVED: To reduce the driving sound and striking sound produced when a stepping motor is returned to its origin by chopping the driving current which is supplied when the motor is driven to stop toward a stopper by means of a zero-returning means and, at the same time, lowering the on-duty ratio of the chopping signal as the motor approaches the stopper. SOLUTION: In step 201, whether or not the zero-returning process of a stepping motor is completed is judged and, when the process is not completed, step 202 is started. In step 202, the driving current of the motor is chopped when the motor is driven in steps toward a stopper and, at the same time, the on-duty ratio of the chopping signal is gradually lowered as the motor approaches the stopper. When the zero-returning process is completed, step 203 is started and the zero-returning process is terminated. Therefore, the driving sound and striking sound which are produced when the motor is drive to return its origin can be reduced.

Title: Surface acoustic wave element and its production
Inventor: SONE TAKEHIKO
IPC: H03H3/08
Filed: 1985-11-29
Abstract: PURPOSE:To increase the reflection factor of a reflector and to reduce the size of a surface acoustic wave element by increasing the line width ratio of the reflector using metallic strips which are not connected with each other. CONSTITUTION:Here 0.5<etaR<1.0 is satisfied with etaR=LR/(LR+SR), where the metallic finger width is referred to as LR, the space between metallic fingers as SR and the line width ratio as etaR respectively with a reflector 3. As a result, the reflection factor using metallic strips is improved together with a small size of a surface acoustic wave element. Furthermore the capacity ratio of the wave element is reduced when it is used to a voltage controlled oscillator. Thus the frequency variable width is increased and the size of a filter containing a reflector for surface acoustic waves is reduced together with reduction of the insertion loss of the filter.

Title: Servo circuit of disk reproducer
Inventor: ITO TAKESHI
IPC: G11B7/09
Filed: 1984-12-20
Abstract: PURPOSE:To attain control of a servo loop gain with simple constitution by using a pulse width modulating means consisting of the 1st current supply circuit, charging/discharging circuit which produces sawtooth wave signals, and a comparator which gives the modulation of pulse width to an error signal and a servo gain control means. CONSTITUTION:The output of a level comparator 37 is equal to the tracking error signal which is applied with pulse width modulation based on the sawtooth wave signal that is prescribed by an output current I1 of a current supply circuit 38. This pulse width modulated signal is supplied to a tracking actuator oil via a drive amplifier circuit for execution of a tracking servo action. Here a switch circuit 42 is turned on by a gain-down signal Gdown, therefore, a capacitor C is charged by a current (I1+I2). Thus the slope of the sawtooth wave signal is made sharp which is applied to the reverse input terminal of the comparator 37. As a result, the pulse width of the pulse width modulated signal is reduced to the same change of the output voltage level V of a full- wave rectifier circuit 35. Then the tracking servo loop gain is reduced.
