Title: Steering controller for continuously variable transmission drive vehicle
Inventor: TAKANO MASAKATSU
IPC: B60K17/30
Filed: 1995-04-20
Abstract: PURPOSE:To provide the optimum steering characteristic at all times even if vehicle speed is changed, in the case of a vehicle whose steering is conducted by changing right and left drive wheel rotation numbers. CONSTITUTION:A work vehicle 1 is equipped with a front wheel Wf to be steered by means of a steering handle 8 and rear wheels Wr to be driven through a transmission T furnished with a hydrostatic type continuously variable transmission in its inside. A speed shift operation device M to conduct the speed shift control of the transmission T carries out the speed increase/decrease of the right and left rear wheels Wr at the same rotation number by the operation of a change lever 10 and at the same time generates a rotation number difference at the right and left rear wheels Wr by the operation of the steering handle 8. A steering characteristic based on the operation of the steering handle 8 is changed according to a vehicle speed to be set by means of the change lever 10, and as a result, even if the vehicle speed is changed, an adequate steering characteristic can be obtained.

Title: Speech recognizing device
Inventor: MOTODA YOICHI
IPC: G10L15/12
Filed: 1988-04-20
Abstract: PURPOSE:To eliminate the influence of environmental noise by providing a means which carries on DP matching on an end point free basis between a part following the halt position of a standard pattern and a part nearby a point preceding the temporary halting point of an input pattern according to the degree of difference as a border condition. CONSTITUTION:A DP (dynamic programming) matching part 4 calculates the degree of difference proportional to the length of standard pattern time based upon an input pattern 1 outputted from an input pattern memory 3 and the standard pattern (j) outputted from a standard pattern memory 2. Namely, the degree of difference at a point P1 is used as the border condition to carry on the DP matching on the end point free basis between the partial pattern following the halt position Q on the standard pattern side and the periphery K2 of the point preceding the temporary halt point of the input pattern. Then even if a noise is generated in a half section and a speech is misdetected, the noise component of the input pattern is skipped during the DP matching and the standard pattern having the smallest degree of similarity is normalized with the standard pattern length J finally and outputted as a standard result R. Consequently, even if there is a nonstationary noise, the recognition performance at a normal time can be maintained.

Inventor: NAKABE KOUJI
IPC: H04B7/26
Filed: 1984-05-14
Abstract: PURPOSE:To utilize the titled detector for system control such as channel avoidance by detecting the light degree of interference of the same channel and detecting quantitatively the degree of interference. CONSTITUTION:An output of each stage of an intermediate frequency amplifier 20 is detected respectively by diodes 22a-22c and a rectified signal is synthesized by a synthesizer 23 to obtain a DC output proportional to the strength of an input signal and the intermediate frequency component is eliminated from the output of the synthesizer 23 by a low pass filter 24. Since it is possible that a beat component based on the same channel interference with the level fluctuating component (nearly less than 100Hz) and a beat component (nearly over 10kHz) due to the adjacent channel interference are generated in the output of a low pass filter 24, a band pass filter 25 is used to eliminate an unnecessary signal and extract the beat component only based on the same channel interference. A rectifier circuit 26 rectifying the beat component extracted by the band pass filter 25 supervises the same channel interference quantity by supervising the said DC level at a same channel interference level supervisory terminal 27.

Title: Picture input-output device
Inventor: OTSUKA KENICHIRO
IPC: H04N1/04
Filed: 1988-04-18
Abstract: PURPOSE:To make the title device lower in cost, compacter in constitution, and higher in reliability by performing the fast forwarding of a reading original, recording medium, such as recording paper, etc., or head, such as reading head, printing head, etc., by switching the excitation system of a pulse motor. CONSTITUTION:An excitation selection circuit 91 is a switching means which switches the excitation circuit of a pulse motor M between a 1 to 2-phase excitation circuit 95a and 2-phase excitation circuit 95b. Since the 1 to 2-phase excitation system is a system which alternately performs 1- and 2-phase excitation on the motor M and the pulse motor M is accelerated at the time of 1-phase excitation, but stopped at the time of 2-phase excitation, the stepping angle of the motor M is small. On the contrary, the 2-phase excitation system performs 2-phase excitation on the motor M at every moment and the stepping angle becomes double of that of the 1 to 2-phase excitation system, since this excitation system is basically the same as the 1-phase excitation system and the motor is accelerated at every moment. Since the motor M rotates at the double speed when the stepping angle of the motor is doubled, fast forwarding of a recording medium or head can be realized. Therefore, fast forwarding of the medium or head can be realized without changing the driving frequency and reduction ratio.

Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To attain stable operation of a three-phase rectifier, by changing the dead time of control pulses of control elements on positive and negative potential sides of respective arms, based on input phase voltage.

The dead time of the control pulses of control elements on positive and negative potential sides of the respective arms can be changed with input phase voltage. It is thus possible to attain a three-phase rectifier power factor improving circuit which can prevent failures which are caused by simultaneous on-operations of the respective arms, and has few harmonic components.
