Title: Braking force control device
Inventor: KAWADA MAMORU
IPC: F16D65/18
Filed: 1994-03-25
Abstract: PURPOSE:To prevent the reduction of the braking force even in the case where a fault is generated in a bellows of a front and a rear shafts by forming the structure that an outlet of a double check valve is connected to a proportion relay valve and that a magnetic valve is opened when the pressure of a pressure switch is reduced to predetermined value or less. CONSTITUTION:When a fault is generated in a bellows 5 of an air suspension, a pressure switch 8 to be turned when the internal pressure of the bellows 5 achieves a pressure, which is never generated during the general travelling, is turned, and magnetic valves 7, 9 are opened, and the high-pressure air is flowed from a second air tank 11 into a proportion relay valve 13 through a double check valve 6. Consequently, supply of the air to a brake chamber 4 is reset to the ordinary condition, and the brake is restored. During the ordinary travelling, when the pressure of the bellows 5 of a rear wheel is lowered by the movement of a load due to the braking, the signal pressure is transmitted to the proportion relay valve 13 through the double check valve 6, and the supply air pressure to the chamber 4 is lowered so as to prevent the wheel lock.

Title: Controlling device for timing of ignition, of internal combustion engine
Inventor: IWATA TOSHIO
IPC: G01M15/00
Filed: 1980-04-23
Abstract: PURPOSE:To control the timing of ignition in accordance with normal knocking by withholding input from a lowpass filter through which a reference value is to be found while knocking is generated in a device wherein the reference value for controlling the knocking is found from the averaged value of noises. CONSTITUTION:A signal detected by an acceleration sensor 1 and a filter 2 is inputted in a differential amplifier 5, while it is also inputted in a noise level detector 4 such as the lowpass filter, and thereby it is made to be a reference value of the differential amplifier 5. When knocking is generated, an analog gate 3 is turned off by the output of the differential amplifier 5 and thereby any signal is not inputted in the circuit 4, and accordingly, the reference value is not changed even by  large knocking signal. In addition, even when the gate 3 is turned off by the large knocking, the reference value turns small according to the time constant of the circuit 4. By this constitution, the timing of ignition can be controlled in accordance with normal knocking.

Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To form a bump electrode having a high adhesion with respect to an external electrode in a semiconductor device and which has a low contact resistance. SOLUTION: A native oxide film on an Al electrode 1 of a semiconductor device is removed for its cleaning. Thereafter the device is immersed into an alkaline solution, containing Ni held at a temperature of 80 deg.C for 20 seconds to form an Ni-particle film 8 having a thickness of 300 to 500 angstroms on the electrode 1. After cleaning, the device is again immersed into the same solution for 20 seconds, to thereby form an Ni particle film 9 having a uniform size of Ni particles formed therein without a gap therebetween. After cleaning the device, an Ni film 6 is formed on the Ni particle film 9 by an electroless plating process. After cleaning the device, an Au film 7 is formed on the Ni film 6 by the electroless plating process. There is no gap between the Al electrode and Ni particle film 9 having a uniform size of Ni particles formed therein without a gap therebetween.  Thus, at the time of forming the Au film 7, no electroless Au plating solution will be immersed into an interface between the Al electrode 1 and Ni particle film 9. Thereby there can be formed a bump electrode having high adhesion onto the Al electrode, 1 and has a low contact resistance value.
