Title: Vortex flowmeter
Inventor: ONODA HAJIME
IPC: G01F1/32
Filed: 1985-05-01
Abstract: PURPOSE:To enable highly accurate measurement of flow rate over a wide range, by arranging an obstacle placed at the center in a tube body in the shape with the width increasing continuously from upstream so that the passage may be choked gradually toward both sides thereof. CONSTITUTION:This vortex flowmeter comprises a square tube body 11, shape- converting sections 12 and 13, flanges 14 and 15, an obstacle 16 and a vortex train frequency detector 17. As a fluid 18 is chocked smoothly with the obstacle 16 toward both sides thereof, stable vortex trains are generated alternately behind it without causing any waste turbulence in the flow. Also, for example, with concave surfaces 20L and 20R on the back of the obstacle 16, the negative pressure will increases at these parts so much as to allow the generation of a large vortex. This enables the measurement of the frequency of vortex trains at a high accuracy leading to a highly accurate measurement of flow rate over a wide range.

Filed: 1995-03-28
Abstract: PURPOSE: To obtain a piezoelectric motor in which large torque can be generated using a piezoelectric element and the speed control is facilitated while prolonging the service life of the motor. CONSTITUTION: A piezoelectric element A displaceable in the direction of thickness and a piezoelectric element B displaceable in the sliding direction are stacked at a holding part 31 and a drive element 32 is bonded thereon thus constituting a drive section 3. The drive section 3 is pressed against the rotor surface through a resilient pressure mechanism part thus exciting the piezoelectric elements A, B with high frequency voltages of the same frequency having a phase shift. Consequently, the drive piece 32 performs elliptical motion in two planes spreading, respectively, in the direction for pressing the rotor and rotating the rotor. in a section where the drive piece 32 presses the contact face of rotor strongly through the piezoelectric element A, the rotor is driven in the direction for displacing the piezoelectric element B and rotated. Moving direction of the rotor is controlled by inverting the phase of one of two high frequency voltages for exciting the piezoelectric elements A, B and the rotational speed of the rotor is controlled by the magnitude of voltage for exciting the piezoelectric element B.

Title: Pattern plotting device
Inventor: SAIDOU YOSHIHITO
IPC: G06T11/20
Filed: 1988-04-18
Abstract: PURPOSE:To completely eliminate the omission of plotting points by synthesizing control signals produced from a reduction process carried out by an OR circuit based on tilt components of a straight line and another reduction process using coordinate updating information on the generation of circles when an ellipse is plotted with reduction of a circle. CONSTITUTION:A signal received from a straight line generating circuit 10 gives a request to a coordinate replacement circuit 30 to update the coordinates in the direction of the short axis of an ellipse. While the output signal of a circle generating circuit 20 gives a request to the circuit 30 to update the coordinates in the direction of the long axis of the ellipse. Thus the circuit 30 performs the replacement of coordinates according to said requests respectively. Then an OR circuit 40 transmits the OR signal of each coordinate replacement request and controls the coordinate output of the circuit 30. As a result, the omission of the drawing points caused when an ellipse is drawn with reduction of a circle can be completed avoided with use of the coordinate replacement information on generation of circles as well as a reduction process carried out based on the tilt component of a straight line.

Title: Arithmetic unit for deviation from track
Inventor: KISHIMOTO SATORU
IPC: E01B35/00
Filed: 1979-07-27
Abstract: PURPOSE: To improve the precision of a track curve by removing a ghost waveform from the track curve by performing required arithmetic as to input measurement data of a track passage deviation or track height deviation obtained in the three- point measuring method.  
     CONSTITUTION: From three-point measurement system 15 provided to a detecting- measuring vehicle, track deviation data ΔY are supplied to A/D converter 16. On the other hand, sampling pulse generator 17 generates sampling pulse SP in proportion to a distance by using distance pulse DP from the detecting-measuring vehicle, A/D converter 16 samples and digitizes data ΔY of every constant distance to obtain deviation value [ΔY], and original-curve arithmetic circuit 18 obtains an original curve. Of the original curve, the curve part or wave component long in gradient part is eliminated by digital filter 19. To eliminate a measurement error when the vehicle body changes in direction greatly as the detecting-measuring vehicle moves, initial-value setting circuit 22 resets an initial value. Thus, the precision of the track curve can be improved.

Title: Distance detection device
Inventor: HARUNARI YOSHIHIRO
IPC: G01C3/06
Filed: 1994-05-09
Abstract: PURPOSE:To reduce effort required for matching a plurality of processing systems by a method where a signal which has been amplified and output earlier in a time- series manner is stored, another signal is then generated by a time-series formation means, both signals are operated and distance information is detected. CONSTITUTION:An operation amplifier MA converts output currents of photodetectors SPC1, SPC2 into voltages. A preamplifier PA receives a signal whose DC portion has been cut at a noninverting input terminal, and it amplifies the signal. The potential of the output of an operational amplifier INT which integrates the output of the PA becomes nearly equal to the threshold voltage of an operational amplifier CP3. As a result, the terminal voltage of a capacitor C3 becomes a difference voltage between the potential of the inverted input terminal of the INT and the potential of the noninverting input terminal. As a result, the offset voltage of the INT and of the CP 3 can be compensated automatically, and the output level in a signalless state of the INT is set to a reference level or lower. At this time, when the output of the INT is swung to only the positive direction with reference to the output level in the signalless state, the dynamic range of the output of the INT is expanded, and an S/N ratio is enhanced.

Title: Inertia plunge-in type starter motor
Inventor: HATAYAMA YOSHINORI
IPC: H02K7/10
Filed: 1982-06-03
Abstract: PURPOSE:To make it possible to prevent the quick return of a pinion after the pinion is enmeshed with a ring gear during the rotation of a motor by a quick return preventing mechanism, and to positively carry out cranking irrespective of load variation and the like. CONSTITUTION:When a starter is started, a clutch outer 2 advances leftwardly together with a clutch roller 3 and a pinion 4 through helical splines 1a and 2a by the rotation of a shaft 1, and a pinion 4 is enmeshed with a ring gear 5. Upon this occasion, a weight 8 pressed by a garter spring 9 extends by a centrifugal force up to a clutch outer stepped part 2b. Hence, the weight 8 is pinched between a shaft groove 1b and the clutch outer stepped part 2b, and the return of the pinion 4 is prevented. Thereafter, when the starting motor is stopped, the rotation of the shaft 1 reduces and the dismeter of the weight shrinks. Therefore, the pinion 4 is returned to the original position by a force exerted by a return spring 7.

Abstract: PURPOSE:To reduce the deterioration of performance due to the waiting time for a block access required to a main storage at a cache miss by prefetching the block data to a cache from the main storage prior to an original access at a cache miss. CONSTITUTION:When the index results of address arrays 3 and 4 show the cache misses, a block is prefetched to a main storage 10 from a memory access control circuit 9 by an address of a counter 2 after a block is fetched to the storage 10 from the circuit 9 by an address shown in a register 1. That is, an access to be applied to the vicinity of a cache access address from a requester is estimated. Then the probability of existence of data is improved to a cache when the estimated access is carried out. Thus it is possible to prevent the deterioration of performance due to the waiting time for a block access required on the storage 10 at a cache miss.
