Title: Light chopper
Inventor: KOBAYASHI IKUTAROU
IPC: G01J1/04
Filed: 1977-12-05
Abstract: PURPOSE: To achieve the improvement in chopper performance by cutting off between an optical fiber and a photo detector by a shield plate which vibrates stably.  
     CONSTITUTION: Mechanical vibrating reeds 5, 5 which constitute a tuning fork vibrator provided with electro-mechanical converting elements 6 vibrate at stable frequencies by the electric signal being applied to the elements 6. The reception of the fine beam light emitted by an optical fiber 1 by a photoelectric transducer 3 is periodically and stably cut off by the edge portion of the shield plate 4 provided to the vibrating reed 5. Hence, light chopping of high performance is accomplished. If the vibrating frequencies of the vibrating reeds 5, 5 are controlled by detecting even order higher harmonics, etc. of the light receiving signal by the light having been chopped, the relative positions of the optical fiber and the vibrating reed may be readily adjusted so as to minimize the even order higher harmonic components.

Title: Detector for metal buried in human body
Inventor: TANAKA HIROTSUGU
IPC: A61B5/06
Filed: 1990-06-04
Abstract: PURPOSE:To detect how deep and how much a metal material is buried into a human body accurately with a simple method, by a method wherein a coil is set internally at the tip of a probe as sensor and a loss of an eddy current of the coil fed with an alternating current is detected to measure a distance to the metal material. CONSTITUTION:When a metal material 45 approaches a probe 2, a high frequency voltage V from an oscillation circuit 61 is lowered in the probe 2 due to a loss of an eddy current to be applied to a second input terminal of a differential amplification circuit 62, to increase a difference from an original high frequency voltage V, which causes a change in the results of comparison from a comparator circuit 64 in a direction in which the probe 2 approaches the metal material 65. As a result, the lighting color of a detection lamp is turned to red with a meter indicating a shorter distance and the sound as a detection buzzer increases in frequency. When the metal material 65 is separated from the probe 2, the lighting color of the detection lamp is turned to green with the meter indicating a longer distance and the frequency of the sound of the detection buzzer decreases, thereby enabling the learning of a position where the metal material 63 is buried accurately.

Title: Dc motor controller of rolling mill
Inventor: MAEDA SHIGERU
IPC: H02P7/298
Filed: 1983-08-11
Abstract: PURPOSE:To suppress the jump of an armature voltage due to the speed rise of a motor at the load removing time within a rated voltage range by controlling the speed command to the deceleration side immediately when the load is removed. CONSTITUTION:A changeover switch 19 selects a setter 10 to control to acceleration or constant speed, and a speed pattern generator 11 outputs a speed pattern having a constant speed range coincident to the set value of the setter 10. A speed control system controls the armature current due to the comparison with the speed detection signal with this speed pattern as a speed command. A field control system controls the field current from the strengthening field so far to a weakening field when the armature voltage of the motor becomes the voltage exceeding the bottom speed. Then, a changeover switch 19 is switched to a setter 18 side by the detection immediately before the load is removed, and the output of the generator 11 is lowered at the prescribed alope to the voltage corresponding to the speed lower than the base speed set to the setter 18.

Title: Structure of low temperature liquid transfer piping
Inventor: KONO KAZUHITO
IPC: F16L51/00
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To ensure the soundness of a piping system without requiring a large space and even in the case that excessive external force caused by a huge earthquake and the like is applied thereto, by connecting coaxially with a transfer pipe a thick bellows formed in the same thickness as the thickness of the transfer pipe. SOLUTION: When low temperature liquid such as LNG being low temperature liquid is passed through an empty low temperature liquid transfer piping system, a transfer pipe 2 lowers its temperature from room temperature to a temperature of the low temperature liquid such as LNG and thermally contracted. In this case, the bellows part 13 of a thick bellows 3 is so formed that crest parts 14 and trough parts 15 are respectively formed into a semicircular arc shape having the same diameter and are also connected zigzag to each other through connecting ring parts 16. The diameters of the crest parts 14 and the diameters of the trough parts 15 are respectively extended by the same pitch, thereby, when the thick bellows 3 is extended to absorb the thermal contraction of the transfer pipe 2, it can be extended without any trouble even though its thickness is formed thick.  In contrast with this, when returning to room temperature, the transfer pipe 2 is returned to the length at the time of room temperature, and the thick bellows 3 can be contracted without any trouble.

IPC: F01N13/18
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To avoid stress concentration of a manifold body so as to improve heat resisting fatigue strength by removing a projecting part formed on a split line of a core, the slit line of which is not parallel to the direction of thermal expansion of the manifold body of the core used in casting an exhaust manifold to be flat.
