Title: Reciprocating pump
Inventor: OOTAKE KUNIHIKO
IPC: F04B53/14
Filed: 1980-12-17
Abstract: PURPOSE: To eliminate necessity of the valve of a piston pump and simplify the structure of the pump, by arranging two pistons oppositely in the main body of the cylinder of the pump, making it possible to change the capacity between the pistons according to the reciprocating motion of the pistons and thus transferring a fluid with the pistons.  
     CONSTITUTION: When the first piston 4 moves formed in the right direction, a liquid in a hollow portion 10 between the first and the second pistons 4, 7 pushes the piston 7 forward against a spring 8. Then, the piston 7 opens a discharge port 3, and the liquid in the hollow portion 10 is forced out from the port 3. The forcing out is completed by the further forward motion of the piston 4. Next, the piston 7 is released from the forward pushing by the start of the backward motion of the piston 4, and the piston 7 is returned to its original position by the elasticforce of the spring 8.

Title: Contour correcting circuit
Inventor: NOZAWA TAKAHIRO
IPC: H04N5/208
Filed: 1993-06-24
Abstract: PURPOSE:To provide a contour correcting circuit which can sharpen its rise and fall without increasing the preshoot and overshoot levels. CONSTITUTION:The delay circuits 12-15 successively delay signals A and produce the signals B-E. The units including a computing element 16 through an amplitude limiter 20 produce the signals G, and the computing elements 21 and 22 produce the signals H and I. A maximum value comparator 23 sets the maximum value of signals H and I and produces a signal J, and a minimum value comparator 24 and an inverse amplifier 25 set the minimum value of signals H and I and produce the signals K by inverting the maximum value of both signals H and I. Then a maximum value comparator 26 sets the maximum value of signals J and K and produces a signal L, and a minimum value comparators 27 and 29 produce the signals M equal to only the negative components of minimum value of both signals J and K. A computing element 30 subtracts the signal M from the signal L to produce a signal N, and a multiplier 31 multiplies the signal N by the signal G to produce a signal O. Then an adder 32 adds a signal O to a signal C to produce a contour corrected signal P.

CONSTITUTION:An attachment member 10 having a fixing section 11 of which the central axis is in conformity with that of a sleeve 7 is fixed to the sleeve 7 in colinear alignment therewith. A rotary cylindrical member 20 is rotatably provided in a cover case 13 fixed to the attachment member 10. The rotary cylindrical member 20 houses a strain induction pipe 30 that is rotatable therewith. A guide section 22 is so constituted that a fixing member 40 is engaged with the strain induction pipe 30 to stop the rotation so that the guide section 22 allows the rotary cylindrical member 20 to hold a test piece 50. As a result, it is not necessary to take off a jig and the like of a work at every measuring operation, thereby reducing a working time and facilitating the preparation working. In the case where a rotary driving source and a driver bit are connected by a rotary shaft as in a multi-spindle automatic screw fastener, a claming torque transferred to a screw is directly measured so that it is possible to always measure the torque with high accuracy.

Abstract: PURPOSE:To take sufficient gradation of a bright part and to widen the dynamic range by forming a video signal by one field period from a signal read or integrated or added for one field period. CONSTITUTION:A signal charge generated in a light receiving section of a photoelectric conversion section 1 is stored to a storage capacitor for a prescribed period in response to an external incident luminous quantity and the signal charge stored for each picture element is read sequentially by a read out scanning section 3 to generate a time series electric signal corresponding to the spatial distribution of the incident luminous quantity. In this case, at least part of the signal charge stored in the storage capacitor is read to the outside of the storage capacitor for twice or over within one field period of the video output signal and the signal read for one field period is integrated or added to generate the video signal for one field period. Thus, the deterioration in the effective sensitivity is suppressed and even when the incident luminous quantity is increased, the luminous quantity dependency of the output signal is not weaken. Thus, the gradation of the bright part is taken sufficiently to widen the dynamic range.
