Title: Power switching device
Inventor: KOCHA MASAHARU
IPC: F16H3/08
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To smoothly switch a motive power by carrying out a motive power- switching by a selective engagement of a centrifugal clutch by a shift means and an output adjusting means. SOLUTION: When an operator releases a throttle lever 24 and shifts a shift lever 40 from a first shift position 40a to a second shift position 40b and a driving shaft 16 is axially moved to a position P2 through a shift fork 40d, a shoe member 28 of a centrifugal clutch mechanism 32 is aligned with a cylindrical portion 38c of a drum portion 38 in a moving space S. When the operator grasps the throttle lever 24, an output of an internal combustion engine 2 is increased. When a rotation speed of the driving shaft 16 is raised to become a predetermined revolution number or more, the shoe member 28 is radially and outwardly moved in resistant to an urging force of a return spring by a centrifugal force to friction-engage with an inner periphery of the cylindrical portion 38c.  Thereby, a motive power is transmitted to an output pulley 14 through the drum portion 38, a driving gear 48 and a driven gear 50 and a speed is reduced from a high speed to a low speed and a rotation driving is carried out.

Inventor: ANDREW PETER BRADLEY
IPC: H04N1/41
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To utilize adaptive wavelet packet decomposition by utilizing a first number and a second number, in order to decide whether or not a component has been decomposed into sub-components. SOLUTION: An input image 102 is supplied to a transform block 110, which performs a desired linear transform and produces a corresponding transform coefficient 112. At this time, it is decomposed to each component that has a component in which low frequency components, high frequency components and high frequency components and low frequency components coexist. A first number of each coefficient of the previous component that has the dimension which exceeds a prescribed component threshold is decided. A low frequency sub-component, offense and defense produce each decomposition of a sub-component column which has a sub-component in which a number sub-component, a high frequency number sub-component and a low frequency number sub-component coexist.  A second number of each coefficient of the sub- component which has the dimension that exceeds a prescribed sub-component threshold is decided. The first and second numbers are utilized to decide whether or not the component has been decomposed into sub-components. Decomposition is performed with respect to the decomposition of a prescribed level, while subjecting each step to the respective sub-components.

Title: Fuel injection amount controller for internal combustion engine
Inventor: TERAOKA MASAHIKO
IPC: F02M69/00
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To facilitate the control of fuel injection amount even if injection timing is changed and pressure at the end of an injector changes at the time of fuel injection, by correcting a correction coefficient according to the injection timing in changing the injection timing. SOLUTION: When intake simultaneous injection is conducted, pressure at the end of an injector does not meet predicted (estimated) pressure, therefore, correction amount P corresponding to a crank angle Tang is calculated. Target fuel injection time TAU is multiplied by a correction coefficient KFPC with a value after being corrected with the correction amount P to calculate final fuel injection time. As a result, the later the injection timing is, the more the pressure at the end of the injector becomes negative, however, the correction coefficient KFPC is corrected with the correction amount P corresponding to the crank angle Tang to prevent fuel injection time or fuel injection amount from increasing, thus causing air-fuel ratio not to be deviated.

Title: Acceleration sensor
Inventor: OMURA KAZUYO
IPC: G01P15/08
Filed: 1989-10-25
Abstract: PURPOSE:To obtain a sensor which takes out a constant sensor output without being affected with variation in the temperature of damper oil by charging a viscous body which varies in viscosity with a produced electric field in a housing. CONSTITUTION:The damper oil 7 is sealed in an inner case 9 and a vibrator 5 in cantilever structure is incorporated. Then a weight 3 which is applied with acceleration incorporating an F-directional component moves right/left to apply bending moment to a beam 1. A strain gauge 11 converts a strain quantity based upon the bending moment into an electricity quantity and the transduced signal is amplified 3 and sent out through a signal line 15. When the acceleration is measured, a portable power source 27 is not connected, so no voltage is applied to the damper oil 7 and the viscosity is set to a specific low value. The weight 3, therefore, moves greatly and a vibrator 5 securely detects even fine acceleration. When the sensor is transported, a voltage is applied to the damper oil 7, which increases in viscosity according to the applied voltage to suppress the momentum of the weight 3.

Title: High speed and highly accurate buffer amplifier
Inventor: NAKATANI TAKAYUKI
IPC: H03F3/34
Filed: 1986-11-19
Abstract: PURPOSE:To obtain a high speed highly accurate buffer amplifier provided with a low distortion factor by adding a current compensation circuit always compensating a current flowing to an active element to be constant in response to the change in a voltage given to a load of an emitter of the active element being a component of an emitter amplifier. CONSTITUTION:The current compensation circuit 5 is connected to the emitter of the active element 2. When a current flowing to the active element 2 is increased and its output voltage changes, a current flowing to a load 4 is changed. The output voltage change is given to a base of a transistor (TR) 6 via a level shift circuit 8 and a current flows to a dummy load 11. In selecting the impedance of the load 4 equal to the impedance of the dummy load 11, since the increment of the current flowing to the load 4 and the decrement of the collector current of a TR 7 are equal and the current through the active element 2 is unchanged. Thus, the current is always kept to a prescribed value independently of the excitation of the signal in the active element 2 and the mutual conductance (gm) and the current amplification factor beta are kept constant, then the distortion factor is improved.
