Title: Fixing method for deflection yoke
Inventor: KOBAYASHI MIKIHARU
IPC: H01J29/76
Filed: 1989-12-29
Abstract: PURPOSE:To stick a coil with excellent heat resistance and improve workability by fixing the coil to a core with a reaction type hot-melt adhesive. CONSTITUTION:A deflection yoke is assembled at the rear section of a cathode- ray tube 4, and a coil 2 must be fixed to a core 1 after image adjustment is performed so that the adjustment is not deranged. The coil 2 is stuck and fixed to the core 1 at an optional position with a reaction type hot-melt adhesive 5. The reaction type hot-melt adhesive 5 is a two-step hardening type adhesive which performs the initial fitting in about several seconds by cooling and is completely hardened when reacted with the moisture in the air and the moisture in a stuck body, initial fitting is performed in a short time, and the sticking force at a high temperature is increased after the complete hardening. Sticking with excellent heat resistance can be performed with only one type of the adhesive 5, and workability can be improved.

Filed: 1993-12-24
Abstract: PURPOSE:To prevent the deterioration in the reliability and lowering of the high-speed operating properties of a semiconductor device resulting from the disconnection of a T type gate having fine gate length and the increase in the electric resistance. CONSTITUTION:When a gate opening section 10 is formed to an Si3N4 film 3 as an insulating film while using an Al film 5 with an opening section 9 having fine size as a mask, the upper section of the Si3N4 film 3 is removed through isotropic etching, and an opening wider than the mask opening section 9 is formed.

Consequently, the gate opening secion 10 having an inclination in the upward opened direction in approximately the same size as the mask opening section 9 at a lower end section is shaped. A gate metal is deposited, and an approximately Y-shaped gate electrode 7 is formed. Accordingly, the closing of the upper edge of the gate opening section 10 by the gate metal and the extreme reduction of size in the lateral direction of the deposited gate electrode 7 are prevented, and gate length is formed in fine size, thus obtaining high reliability and high-speed operating properties.

IPC: G21C3/324
Filed: 1992-12-28
Abstract: PURPOSE:To make checking and handling easy and improve work efficiency by avoiding a part of clip attached at the upper part of a channel box. CONSTITUTION:By avoiding a part of channel box clip 12 periphery, it is shaped not to cover the upper side of tie-rods.

Also, checking and handling become easy, welding length becomes short, pressure loss decreases and the total weight also decreases. Furthermore, by optimizing the shape of the avoided part in the clip 12, the periphery of the clip can be used as a guide for accessing to the tie-rods or washers.

Abstract: PROBLEM TO BE SOLVED: To improve breakdown strength between a base and a collector of a lateral PNP transistor. SOLUTION: A field electrodes 22 is provided on an insulating film 21 and a LOCOS oxide film 18 formed on the surface of an island 20, and an emitter electrode 25 which is formed on and near the interface between a base region and an emitter region 15 and causes the field electrode 22 and the emitter region 15 to contact each other is provide. Since the filed electrode 22 is extended onto the LOCOS oxide film 18, the influence of an electric field L (vertical component) given to an Si surface of this portion can be reduced. Particularly, at an end portion of a depletion layer terminating on the Si surface, the intensity of the electric field L is reduced by an amount corresponding to the thickness of the LOCOS oxide film. On the other hand, the end of the depletion layer is terminated outward by an electric filed M entering from around the LOCOS oxide film. Thus, breakdown due to concentration of the electric filed can be prevented.
