Abstract: PURPOSE:To reduce in size a power source by operating in advance a clamping force at a plunger, and applying a driving voltage from both normal and reverse directions to piezoelectric elements. CONSTITUTION:An automatic valve B is composed of a piezoelectric actuator A. In the actuator A, an axially telescoping plunger P is mounted in a cylindrical case having front and rear walls (a), (b), and four clamping and stroke piezoelectric elements (e)-(h) are disposed on the outer periphery. The stroke elements (g), (h) are secured to the end of a stationary bridge (d), and the clamp elements (e), (f) are secured to the outer peripheries of the ends of elastic bridges (i), (j). The ends of the bridges (i), (j) are energized at brake shoes (k), (l) inwardly, and approx. 1/2 of the clamping force is operated in advance at the plunger P. Thus, a pulselike driving voltage is fed from a driver to the elements (e)-(h) to move the plunger P synchronously.

IPC: H01P1/203
Filed: 1994-04-25
Abstract: PURPOSE:To provide a band pass filter which causes no variance without increasing the number of parts by constructing a minute capacitive coupling pattern that includes the necessary parts set opposite to each other at the tips of two lead patterns extended from different conductor patterns. CONSTITUTION:A small high dielectric plate of a capacitor substrate has rather wide width, and the lead patterns 17 and 18 are extended from the conductor patterns 6 and 8 respectively at an expanded part on the upper surface of the substrate. Then the tips of both patterns 17 and 18 are bent like a hook into the parallel parts 19 and 20 which are opposite to each other. These parts 19 and 20 construct a minute capacitive coupling pattern. Thus the characteristic of a band pass filter of such a constitution can be varied by adjustment of the lengths of both parts 19 and 20. Furthermore it is also possible to obtain a minute capacitive coupling pattern by having the tips of both patterns 17 and 18 overlapping with each other.

IPC: G10L21/0208
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To provide a largely improved S/N ratio regardless of the position of a noise source. SOLUTION: When speech recognition is not conducted, the output of a first microphone 1 is designated as a target signal, and the output of a second microphone 2 is designated as a reference signal to conduct an adaptive signal processing for obtaining a noise reduction amount. Then, the output of the second microphone 2 is designated as a target signal, and the output of the first microphone 1 is designated as a reference signal to conduct the adaptive signal processing for obtaining a noise reduction amount. A selection state of the microphones presenting a larger noise reduction amount and a filter coefficient at that time are conserved.  The conserving process based on the noise reduction amount is repeated to designate the outputs of the individual microphones as a target signal and a reference signal based on the conserved output selection state of the microphones, and to set the conserved filter coefficient to an adaptive filter 3b for a speech recognition.

Filed: 1988-05-02
Abstract: PURPOSE:To omit the initializing process started at a boot loading action in an active state by holding a program and the data for control of a communication preprocessor in a memory and keeping this processor in a single operation state even when said processor is inactive. CONSTITUTION:When an operator control means 12 issues an inactive request to finish the network service, a network service control means 11 informs an inactive state of a subsystem to a host communication control means 21. A network control means 22 applies the inactive process to the network state and a communication preprocessor 2 in response to the request of the means 21 and gives this information to the means 11. Under such conditions, the means 21 gives a start request to a subsystem single operation means 24 and then waits for the subsystem active information to be issued from a host computer 1 in a state where the control program and data for the processor 2 are held in a memory.

Abstract: PURPOSE:To improve safety by preventing a start of a vehicle at the time of starting of the same, by controlling an increase of a rotation of an engine when a gear is at a reverse running position, in the vehicle such as a tricycle for an off road. CONSTITUTION:When a gear is engaged at a reverse running position and a reverse switch 36 is turned ON, a point (b) is at zero potential and a transistor 64 is turned OFF. As a transistor 67, therefore, is turned OFF as a wave form of a point (a) appears on a point (c) as it is, a thyristor 53 can not be turned ON and starting of an engine is not performed. On the one hand, when the gear is not engaged at the reverse running position and the reverse switch 36 is turned OFF, the transistor 64 is turned ON as a wave form of the point (a) appears on the point (b) as it is. Then when a pulse signal is applied to the transistor 67 from a pulse coil 34, the Tr67 is turned ON and the thyristor 53 is turned ON by a high potential part of a wave form of a point (d). With this construction, the engine is started as charged electric charge of a condenser 31 is discharged.
