Patent JP-S5680553-A (JP)
Title: Wire driving method
Inventor: HASHIMOTO YOSHIO
IPC: G03B27/32
Filed: 1979-11-30
Abstract: PURPOSE: To stabilize the wire system control, by increasing the resonance frequency of a mechanical oscillation system containing wires and keeping tension of the wire always at constant.  
     CONSTITUTION: When a wire 7 is wound along a groove 9b in an adjusting pulley 9 in an appropriate number of turns, if the pulley 9 is rotated (n) turns by friction force due to the movement of the wire 7, a winding position is shifted by (n) pitches. As the winding position changes diameter of the pulley when the winding position changes, the length of the wire in the wound part changes accordingly. Therefore, if the setting is arranged in such a manner that a change of length in wires 7, 8 due to the rotation of a winding pulley 3 and a change of length of the wire 7 due to the rotation of the before described pulley 9 are cancelled with each other, total length of the wires 7, 8 can be always held constant, together with the tension of the wire 7, 8 also held constant. Further, because of no interposition of a spring in the wire driving line, the resonance frequency of a mechanical oscillation system can be kept high, thus the operation of stable control in the driving line contg. the wires 7, 8 can be obtained.

Abstract: PURPOSE:To provide an air spring which possesses the excellent nonlinear characteristic of the reaction force in the lateral direction which can correspond to the high speed of a vehicle at an orbital curved point. CONSTITUTION:As for a pneumatic spring using a laminated rubber 1, a pair of opposed covers 9 for increasing the pneumatic reaction force of a diaphragm in the case of the contact of the diaphragm 4 are installed, and the horizontal direction spring constant of a part of the laminated rubber 1 is set twice the same direction spring constant of the diaphragm part 4, and the horizontal direction spring constant at each rubber layer 2 of the laminated rubber is reduced successively toward the upper layer side from the lower layer side. Accordingly, the horizontal displacement can be suppressed in a reasonable manner, and also the tilt due to the horizontal displacement of the upper surface of the laminated rubber which incurs the reduction of the rigidity of the rubber can be suppressed, and the preferable nonlinear effect is generated.

Title: Detecting device for tape end in width direction of laminate tape
Inventor: MOTOMIYA YUJI
IPC: G01B11/02
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a detecting device which can clearly image-display a tape end in the width direction of a laminate tape. SOLUTION: A laminate tape 1 is composed by gluing a synthetic resin separative film tape whose tape width is smaller than that of a synthetic resin basic material film tape onto the upper face of the synthetic resin basic film tape, and transported from a left side to a right side. A projector 3 projects light and at the same time an irradiation means 5 downward irradiates. Therefore a detection spot is picked up by a CCD camera to be displayed in an image display device 6. In this case, a dichroic filter 7 transmits only light whose color component is damped at a fixed rate from light from the projector 3. On the other hand, light transmitted the laminate tape 1 and the reflected light of downward irradiating light are incident upon the dichronic filter 8, and their transmitted light is inputted to the CCD camera 4.  Therefore, both the width direction end of a base material film tape and the width direction end of a separative film tape can be clearly image displayed in linear form.

Title: Lead storage battery
Inventor: YONEDA TADASHI
IPC: H01M10/12
Filed: 1983-08-26
Abstract: PURPOSE:To decrease the required frequency of water supply and enable stirring of electrolyte to be easily performed by using a lead alloy having a low hydrogen production potential as part of the current collectors of negative plates. CONSTITUTION:A lead alloy containing 0.1% of Ca and having a high hydrogen production potential is used as current collectors for positive and negative plates. In such a battery, part of the current collectors of the negative plates are replaced by current collectors prepared from a lead alloy containing 4.5% of Sb and having a low hydrogen production potential. As a result, decrease in electrolyte caused during charging is suppressed without deteriorating the performance of the battery during its use thereby decreasing the required frequency of water supply to around 1/4 of that for the conventional battery. In addition, stirring of the electrolyte can be facilitated.

Filed: 1982-09-08
Abstract: PURPOSE:To simplify the constitution of a circuit and to miniaturize the size, by using a low-frequency signal extracting means at a monitor circuit in common for a bidirectional transmission line. CONSTITUTION:A failure retrieval signal in an incoming transmission line, e.g., is discriminated at a discriminating system 22-1 at a failure retrieval and applied to an input of a gate 45. A signal is interrupted on an outgoing transmission line and another input of the gate 45 is at ''1''. Thus, the failure retrieval signal is applied to an FF46 via the gate 45, a low-frequency signal is reproduced and when the signal frequency is coincident with a frequency f1 assigned to the own device, an output is generated from a comparator 42, a gate 44 is opened and the failure retrieval signal is returned to the outgoing transmission line via a reproducing system 24-2. Since the gate 45 is provided in this way, the FF46 and an amplifier 47 are used in common to both the relay transmission lines to control the detection of the failure retrieval signal and the return.

Title: Fluorescence measuring apparatus
Inventor: KANEKO MASAYOSHI
IPC: G01N21/64
Filed: 1988-06-27
Abstract: PURPOSE:To inhibit the mixing and overlapping of excitation light with fluorescence in a fluorescence detection optical system by making the excitation light condense to a fluorescent sample turned to a circular luminous flux centered on an optical axis to arrange an excitation optical system optical axis and a fluorescence detection optical system optical axis coaxially. CONSTITUTION:An optical axis 20a of an excitation optical system 20 and an optical axis 40a of a fluorescence detection optical system 40 are arranged coaxially. Excitation light generated from a light source section 21 is reflected with a conical external mirror 31 and a conical internal mirror 32 at a circular luminous flux forming section 30 to be formed to a circular luminous flux. Thereafter, the excitation light is made incident into an excitation light condenser lens 35 and condensed to a fluorescent sample S within a reaction tube 19 to generate fluorescence. The fluorescence is incident into a fluorescence detector 46 in a fluorescence detection optical system through a through hole 41a of a reflector 41 to measure a required component of the fluorescent sample S. The excitation light passing through the fluorescent sample S is diffused from a fluorescence detection optical system optical axis 40a while the number of openings of a fluorescence condenser lens 42 is smaller than that of in internally circular light of an excitation light condenser lens 35 thereby eliminating the mixing and overlapping of the excitation light with fluorescence.
