Title: Wheel bearing equipment
Inventor: AOKI MAMORU
IPC: F16C33/58
Filed: 2002-02-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide a wheel bearing equipment, in which supporting stiffness in the axial direction in turning is improved, while the dimension of the wheel bearing equipment is restrained.  <P>SOLUTION: In a hub-bearing for supporting an axle, a double-row bearing is employed normally, and the position relative to a wheel is decided so that the vehicle weight in a still time may act respectively on the center of the double-row bearing. When a vehicle makes a turn, greater radial and axial loads are imposed on the axle on the side opposite to the turning direction (the left side of the vehicle in the case of a right turn). Consequently, it is effective in making a turn to raise the rigidity of a bearing 8 on the outside in turning rather than a bearing 9 in the inside row. In the present invention, the rigidity of the bearing 8 on the flange side is made higher than the bearing 9 on the other side without degrading the bearing, consequently, the rigidity in turning is improved.  <P>COPYRIGHT: (C)2003,JPO

Inventor: UENO SHUICHI
IPC: H01L29/78
Filed: 2002-02-13
Abstract: <P>PROBLEM TO BE SOLVED: To provide a semiconductor device including a diode of a MISFET structure having a current voltage characteristic near to the ideal diode characteristic.  <P>SOLUTION: Negative charges (for example, electron) 8a is trapped in the side of drain region 2 among a silicon nitride film 4b provided between the silicon oxide films 4a, 4c. When the negative charges 9a are trapped to induce charges 9a in a channel, a threshold value to form a channel of MISFET is different depending on the type of bias of forward bias and backward bias if a bias voltage is applied between the drain and source. Namely, under the backward bias, formation of channel becomes insufficient and a current does not easily flow between the source and drain. However, the channel is formed sufficiently under the forward bias and thereby a current between the source and drain flows easily. Accordingly, the current voltage characteristic near to the ideal diode characteristic can be obtained.  <P>COPYRIGHT: (C)2003,JPO
