Patent JP-H01144390-A (JP)
Title: Control center
Inventor: AIZAWA OSAMU
IPC: H02P23/00
Filed: 1987-11-27
Abstract: PURPOSE:To conduct the performance test of a unit safely by automatically disconnecting a main circuit and a primary winding of a transformer for operation under the state in which the unit is led out into the position of the test. CONSTITUTION:Since a main circuit 3 and a primary winding 10a of a transformer 10 for operation are connected through a normally-closed contact 16b for an auxiliary relay 16 on normal operation, the primary winding 10a side of the transformer 10 for operation is supplied with power supply from the main circuit 3. When a secondary winding 10b of the transformer 10 for operation is supplied with power supply for a test from the outside under the state in which a unit is led out into a position where it is disconnected from a main- circuit power bus 1 and a load side induction motor 9, on the other hand, the low voltage of a tertiary winding 10c is fed as motor control power. Since a coil for the auxiliary relay 16 is excited and the normally-closed contact 16b is opened at that time, main circuit voltage generated in the primary winding 10a does not transfer to the main circuit. Accordingly, a performance test can be conducted safely without a contact to main circuit voltage.

Title: Differential-pressure detecting device
Inventor: TANITSU TAKAHIRO
IPC: G01L13/06
Filed: 1990-11-02
Abstract: PURPOSE:To make it possible to suppress the fluctuation of a zero point and the stress generated in a protecting diaphragm by setting the ratio between the diameter of the operating part of each side diaphragm and the diameter of a hole and the ratio between a central diaphragm and the thickness of a plate within specified ranges, respectively. CONSTITUTION:Side diaphragms 62 are laminated on both side surfaces of a central diaphragm 61 and have the same diameter and the same material as those of the central diaphragm 61. The diaphragms 62 have the disk shape. Circular holes 62a are formed at the central parts of the side diaphragms 62. Thus, the friction caused by the deviation in the direction of the radius in the displacement at the central parts between the central diaphragm 61 and the side diaphragms 62 is eliminated. The ratio between the diameter of the operating part of each side diaphragm 62 and the diameter of the hole and the ratio between the central diaphragm 61 and the plate thickness are limited in the ranges of 0.1 - 0.25 and 1.0 - 1.2, respectively. Thus, the maximum values of the stresses which are generated on the central part and the circumference of the operating part of the central diaphragm and on the inner surface of the central hole and the circumference of the operating part of the side diaphragm can be suppressed. In this way, the fluctuation of a zero point and the stress generated in the protecting diaphragm 60 can be suppressed.

Filed: 1988-11-28
Abstract: PURPOSE:To prevent deterioration in picture quality by detecting a peak voltage among 3 colors of color difference signals and decreasing the color saturation and contrast when voltage difference level between the amplitude voltage and a negative luminance signal reaches an input voltage in matching with the saturation of a drive transistor (TR). CONSTITUTION:In the case of receiving a color bar, each color difference signal is led through diodes 20, 21, 22 and a peak value among the signals is outputted.

Abstract: PURPOSE:To realize the monitoring of a welding current with high reliability by dividing the electrification section of the resistance welding to change by stages like the preheating, the main electrifying and the postheating into plural sections and setting a reference current value for each section to monitor the welding current. CONSTITUTION:The resistance welding is performed by changing the electrification by stages with the lapse of time like the preheating, the main electrifying and the postheating. At the time of monitoring, the electrification section is divided into the preheating T1, the main electrifying T2 and the postheating T3 and the number of cycles of the supply current and the reference current value for each section are set in a setting means 1. When the welding is started, an arithmetic means 3 samples the number of the whole cycles in each section inputted from a welding current detection means 2 with a prescribed period for each section and operates an effective value for each section from an instantaneous value. A decision means 4 compares the effective value for each section calculated by the means 3 with each reference value set by the means 1 to decide acceptance or rejection of a welded result. In this way, the overall area of the welding process can be accurately monitored.

Title: Rotation sensor
Inventor: KAWAKAMI TAKAHIRO
IPC: G01P3/487
Filed: 1990-11-05
Abstract: PURPOSE:To detect rotation highly accurately by supporting a printed board to which a Hall IC is attached with a material having a large thermal expansion coefficient, displacing the IC in the rotating direction of a magnet or in the reverse direction by temperature change, and correcting the change in magnetic flux density by the adjustment of the interval between the magnet and the IC. CONSTITUTION:A printed board to which a Hall IC 7 is attached is supported with a thermal deforming member 5. The member 5 is thermally expanded at high temperature, and the Hall IC is brought close to a rotary magnet 5. Even if the magnetic flux of the magnet 5 is decreased by high temperature, the effective amount of the magnetic flux acts on the Hall IC 7. Thus, the detection of rotation without abnormality is made possible. The change in magnetic flux density affecting the IC 7 caused by the gaps between the Hall IC 7 and the magnet 5 corresponds to, e.g. gaps 0.6 - 0.8 as shown in the figure. Therefore, when the interval between the member 15 and the gap is set beforehand, it is possible that the approximately same magnetic flux density as in normal temperature can be made to act on the IC 7. Thus, the detecting accuracy is improved.

Abstract: PROBLEM TO BE SOLVED: To set a section in a desired three-dimensional position quickly, accurately and easily by providing an altering means for arbitrarily altering at least either of the direction and the position of an area in a three-dimensional space. SOLUTION: A reference image is stuck to a reference section SEC2, whereby images of two sections, the reference section SEC2 and a current image-pickup section SEC1 are displayed in three dimensions on a sectional position display window 402.
