Abstract: PURPOSE:To prevent generation of damage on the cover glass surface of a light emitting and receiving element at the time of attaching and detaching an optical fiber by disposing a spacer plate having a hole larger than the core diameter of this fiber between the light emitting and receiving element and the optical fiber. CONSTITUTION:A housing 1 has a point 11 to house the light emitting and receiving element 7 at its one end and the light emitting and receiving element 7 (for example, LED, etc.) is housed at this point 11. In succession, the spacer plate 3 is arranged and this spacer plate 3 has a tapered hole 30 having the bore larger than the core diameter of the optical fiber and larger than the clad diameter on the light emitting and receiving element side. The optical fiber stops in mid-way of the hole 30 of the spacer plate 30 at the time of inserting and fixing the optical fiber and, therefore, the strike of the optical fiber with the cover glass of the light emitting and receiving element 7 does not arise. The spacer plate 3 is preferably formed of metallic materials, such as stainless steel and brass, which have a light shielding function.

Title: Pulse motor
Inventor: YANAGIDA YASUTO
IPC: H02K37/20
Filed: 1990-11-30
Abstract: PURPOSE:To prevent generation of a torque ripple, and to obtain a pulse motor capable of holding generated torque constant by so setting a gap between a stator and a rotor that magnetic resistance becomes a sine wave, and providing salient poles of the number of times of integer number of 3 on the stator. CONSTITUTION:Magnetic elements 11, 12 have salient poles 111, 112,..., 116, 121, 122,..., 126 on the outer peripheries in such a manner that the phases of adjacent poles are shifted from each other by 120 deg., and teeth of a rotor 2 opposed to a stator 1 are so formed that the phases of magnetic resistances of air gaps between a pair of the elements 11, 12 and the rotor 2 are shifted by 180 deg.. Accordingly, 3-phase exciting currents flow through the pulse motor of this structure, and hence reluctance torque and detent torque as the entire pulse motor become together '0'. With respect to ibl torque, since the phases of the waveforms of the layers are deviated at 120 deg., ibl torque as the entire motor becomes a predetermined value. Accordingly, a constant torque having no torque ripple can be generated.

Abstract: PROBLEM TO BE SOLVED: To obtain a measuring method in which the vibration of a structure is measured on the ground without attaching a measuring apparatus to the structure. SOLUTION: On a structure P which is vibrated, a point in which its luminance is changed due to a change in its tone of color or a point in which the difference of its luminance from a background is clear is used as a point to be noticed, and the point is photographed by a CCD camera 10. The vibration of the point to be notices is recognized as the shading change point of a pixel on an image.

Abstract: PURPOSE:To always set an adequate switching action mode regardless of a quality of a substance intended tested by trying to measure a measured object of light, acoustic wave, magnetism, etc., in a condition that the detection objective substance is provided and not.

IPC: G05B1/02
Filed: 1989-12-27
Abstract: PURPOSE:To suppress an overcurrent in a bridge circuit by detecting a failure of a sensor part thereby to turn a feedback transistor into the nearly OFF state. CONSTITUTION:In a wind velocity sensor 10, is a heater temperature sensor 12 is poorly shortcircuited or a temperature sensor 14 for temperature compensation fails to be properly opened, a voltage impressed to a non-inverting input terminal 26b of an operational amplifier 26 becomes larger than a voltage impressed to an inverting input terminal 26a. Therefore, an output of the operational amplifier 26 is saturated in a positive direction, with a feedback transistor 28 being held in the ON state. An overcurrent flows in a resistor 16 and the resultant voltage decrease is added between a base and an emitter of a protecting transistor 30. Accordingly, the transistor 30 is turned ON and a source voltage Vcc is impressed to the input terminal 26a, and the output of the operational amplifier 26 becomes smaller, resulting in that the transistor 28 is nearly OFF. In this manner, the overcurrent flowing from the transistor 28 to the resistor 16 can be restricted.
