Title: Current application controller of electric motor
Inventor: SUGIYAMA MASANORI
IPC: H02P25/08
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To quickly discharge the residual voltage of a capacitor immediately after turning off of an electric motor driving power source, and also, materialize this substantially without power consumption during power on and without needing the addition of a special discharge circuit. SOLUTION: This device is equipped with a motor driver 18 which is connected to a DC power PB through a power switch PR, a current controller which controls the value of the current applied to the electric motor, and a discharge control means ECU which directs the current controller to apply a current. The discharge control means ECU directs the current application to rotate it in the reverse direction to the rotation of the motor. When the rotational speed is under the set value, this means directs the simultaneous current application of all phases. This directs the current application which substantially zeroes the sum total of the torque that each phase of the motor generates. This decides the objective current value corresponding to the rotational angle of the motor and directs this current application.

Abstract: PURPOSE:To make it possible to perform automatic optical measurement of a body having an arbitrary color by using a color CRT, by providing a means, which quantitatively adjusts the hue, saturation and luminance of the color CRT and a means which optically compares an unknown light emitting body and the screen of the color CRT. CONSTITUTION:Rectangular prisms 11 and 12 transmit the light from a CRT1 downward. Meanwhile the light from an unknown light source 10 is transmitted downward through the prisms 11 and 12. When the light source 10 is not self-light emitting type, standard light is projected or transmitted. A deflecting circuit 2 is adjusted so as to obtain approximately the same shape and size as those of the light source 10. Even though the light source 10 has a circular shape, if a circuit, which can give various raster shapes, is used in a control circuit 7, the adjustment can be performed. A photoelectric transducer 20 generates the output corresponding to luminance of 100 as required and the circuit 7 is controlled. Adjustment is performed so that the CRT and the power source 10 have about the same luminance. Fine hue, saturation, and the like are adjusted by resistors 4-6. CRTs 13 and 14 are visually compared. When both CRTs display the equal color, the optical property of the light emitting surface 10 is measured from the scale of the resistors 4-6 and 8 and the like.

Abstract: PURPOSE:To prevent the improper plating, further decrease in the characteristics of a semicnductor element and the lifetime thereof by increasing the length of a linear part of a rectangular metallic plate of the bottom of a hole of a semiconductor element container longer than the linear part of the hole. CONSTITUTION:The lengths of linear parts of a rectangular hole 51 of a ceramic package are represented by A1, B1, the linear parts corresponding to the metallic plate 52 on the bottom of the hole are designated by A2, B2, and are  formed in the relation of A1<A2, B1<B2. At this time, the radii of the circular  arcs of four corners of the metallic plate become sufficiently small, and when  they are fixed to the metallized layer in the hole 51, a gap having a length longer than the prescribed length can be existed between the hole 51 and the  metallic plate. Accordingly, when the Ni plating or Au plating continued to the  exposed surface is performed after the fixture, plating solution can readily impregnate to the gap, thereby forming the plating laye of the prescribed thickness  and effectively performing cleaning treatment, and no deterioration occurs in  the quality of the plating layer by the hat at the time of fixing the element.  Accordingly, the characteristics and the lifetime of the element can not be deteriorated. Mo, Fe-Ni or Fe-Ni-Co alloy is used for metallic plate.
