Title: Thyristor and bidirectional thyristor
Inventor: MIYAMOTO MASATO
IPC: H01L29/74
Filed: 1995-01-26
Abstract: PURPOSE: To provide a thyristor which is protected from a counter electromotive force generated in the OFF state even when the thyristor is applied to an inductive load.

Filed: 1984-01-26
Abstract: PURPOSE:To reduce doming and prevent the color shift of a picture by partially forming a layer that is principally made of glass at least on the surface of an electron gun side of a shadow mask provided with a number of premeation holes on its rectangular principal surface. CONSTITUTION:A shadow mask 5 arranged in proximity and opposition to the screen 4 of a color picture tube is provided with a layer 11 made of vitrified lead silicate glass and on the surface of the electron gun 6 side while being formed symmetrically and rectangularly on both sides 1/2y including the central line h-h in the direction of the central line v-v and from 1/2w to 1/2x on both sides of the central ine v-v in the direction of the central line h-h. As a result, since the mislanding of an electron beam caused by the doming of the shadow mask 5 is increased toward the outside area from the central vicinity, the residual stress taking place when the glass and metal are sealed together can be reduced and the deterioration of color purity can be prevented by partially forming the layer 11.

IPC: H03F3/45
Filed: 1990-01-23
Abstract: PURPOSE: To suppress a common mode signal component by coupling an in-phase signal with an inverted signal. CONSTITUTION: An input signal including a differential component and a common mode component is fed to terminals 10, 12 and an output voltage V3 is proportional to an inverse of a mean value of the input signals VCM<+> and VCM<-> when resistance of resistors R2, R3 is selected equal. An amplifier 18 acts like a buffer whose gain is the unity to apply signal being the inverse of the common mode voltage to a node 26 of an adder circuit network 24. The common mode voltage component appearing at terminals 10, 12 of the adder circuit network 24 is proportional in the magnitude and opposite in the polarity to the common mode voltage signal outputted to the node 26 via the adder circuit network 14 and amplifiers 16, 18 by selecting each resistive component of the adder circuit network 24.  Since a null value is produced at connecting points 28, 30, the effect of a common mode voltage is not given onto output voltages V1 , V2 , which represent a value denoting accurately a voltage difference fed to the terminals 10, 12.
