Title: Hybrid brake lining
Inventor: SHIMOKAWA YUKIO
IPC: F16D65/08
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To effectively reduce squeaking by combining friction materials having difference friction characteristics and protruding the friction material having a relatively low friction factor from the other location. SOLUTION: A brake lining 1 is composed by combining a low μfriction material 3 having a low friction factor loaded in a back plate with a high μfriction material 4 having a high friction factor. The region of the low μfriction material is indicated by a slanting line in the drawing, and it is arranged in a circular-arc shape along a large curvature radius friction sliding direction having a specified width M, i.e., in the direction of an arrow B3 around the rotational center of a brake drum. Low μ friction materials 3 are arranged in both sides of the cross direction of the brake lining 1. The exposed area of the high μ friction material 4 is set larger than the exposed area of the low μ friction material 3 so as to secure braking property.  Thus, during the light brake operation of a small brake operation amount, priority is put on friction between the friction material having a low friction factor and an opposite friction material and therefore the suppression of 'squeaking' is facilitated.

Title: Metal bump electrode section
Inventor: KOBAYASHI TAKAAKI
IPC: H01L21/60
Filed: 1987-03-31
Abstract: PURPOSE:To flatten the upper layer of an electrode to broaden a current passage to metal wirings and to reduce the concentrated resistance by forming a bump electrode forming region inside an interlayer insulating film opening, and forming metal wirings of a lower layer in or out of the region. CONSTITUTION:A bump electrode 8 and aluminum wirings 3 for connecting between the electrode 8 and an element are formed in a bump electrode forming region on an interlayer insulating film 2 for insulating between a semiconductor substrate 1 and the element. After the formation of the electrode 8 is finished, with a barrier film 6 as a mask an unnecessary part is removed. The electrode 8 made of gold is formed on an electrode aluminum 5 and the film 6 to become a current passage in case of electrolytically plating. Since the electrode region is disposed inside of the peripheral edge of the opening, the influence of a step is eliminated to flatten the upper layer of the electrode 8. Accordingly, in case of bonding to the carrier tape, the contacting area is increased. Thus, a current passage with the wirings is broadened, and the concentrated resistance is reduced.

Abstract: PURPOSE:To eliminate the need to install a signal transmission line for a display separately and to perform a specific display on a sensor part by using the signal transmission line which connects a sensor part and a control part for a detection signal and a display signal in common. CONSTITUTION:The high-frequency detection signal which is generated by the detecting means 4 of the sensor part 1 after passing through a capacitor 6 is sent to the control part 2 by the signal transmission line 3 and inputted to a detection signal processing circuit through a high-pass filter 10. A DC-level display signal generated by the display signal generating circuit on the side of the control part 2, on the other hand, is sent by the signal transmission line 3 after passing through a low-pass filter 12 and inputted to the sensor part 1, and inputted to a display means 8 through a low-pass filter 7 to perform the prescribed display on a display means 8. The signal transmission line 3 is therefore used in common for the detection signal generated by the sensor part 1 and the display signal generated by the control part 2 to perform the signal transmission between the sensor part and control part 2. Consequently, the display signal can be sent from the control part to the sensor part without providing the signal transmission line for the display specially.
