Title: Color cathode-ray tube
Inventor: NAKAMURA YUKIO
IPC: H01J29/76
Filed: 1991-03-13
Abstract: PURPOSE:To make a compensation current simple and improve lateral convergence error in screen corners by disposing a convergence compensation yoke in the deflection magnetic field area to form a quadrupole magnetic field. CONSTITUTION:A convergence compensation yoke 4 is located in a position outside the bobbin 1a of a deflection yoke 1 and not covered with a core 1b. A quadrupole magnetic field is formed together with a deflection magnetic field in the bobbin 1a at the position of the yoke 1. Three electron beam emitted from an electron gun 3 are deflected, by the deflection magnetic field of the yoke 1 and passes through the quadrupole magnetic field during the process of undergoing the deflection. This causes the three electron beams to pass always displaced points corresponding to irradiated positions on a panel. Instead of the center of the quadrupole magnetic field, and the intensity of the quadrupole magnetic field at a position horizontally shifted from the center changes in a parabolic wave shape in relation to the vertical direction. Therefore, lateral convergence error in the screen corners can be improved even if current for compensation supplied to a convergence compensation coil is simple.

Abstract: PURPOSE:To enable thermally pressure bonding of an inner lead to an electrode bump at low load by providing suitable ruggedness on the surface to be bonded of the bump and also on the surface to be bonded of the inner lead of a tape carrier type semiconductor device. CONSTITUTION:The surface to be bonded of an inner lead 2 secured onto a carrier tape 1 is formed with sawtooth ruggedness formed by etching on the surface to be bonded to the bump electrode 3 on a tape 4. The lead 2 is made of Cu and plated with Au, and the electrode 3 has Au surface. According to this configuration, the surface of the electrode 3 is initially point contacted with the surface of the lead to concentrate the contact load at the point contact portion.

According to this method, Ni or Cu or the like can be used at plating inexpensively as compared with Au. Even in case of Au-Sn eutectic bonding system, it can prevent a shortcircuit owing to Au-Sn alloy flow-out.

IPC: B60K17/356
Filed: 1995-03-08
Abstract: PURPOSE: To secure driving force when a vehicle is started on a road low in frictional coefficient, and concurrently secure the durability of the device by letting a discharge flow rate reducing means be equipped with a minimum flow rate control means securing the minimum flow rate. CONSTITUTION: When a vehicle is started, and accelerated on a road surface low in frictional coefficient, a front wheel 5 is driven first, however, when the front wheel is slipped, the number of revolution of the front wheel 5 becomes greater than that of a rear wheel 19. When the discharge flow rate of a pump 6 becomes greater than that of a variable capacity pump motor 10, the variable capacity pump motor 10 is turned out to act as a motor, so that the transmission of drive torque to the rear wheel 19 is thereby started. When the line pressure of the pump 6 exceeds a specified value, a discharge flow rate is restricted in response to an increase in pressure, meanwhile, the minimum value of a discharge flow rate will never be reduced to zero, and the specified minimum flow rate is maintained.  Therefore, driving torque is transitionally increased in response to an increase in the difference in the number of revolution between the front and rear wheels, however, driving torque is reduced for an excessive increase in the difference in the number of revolution.
