摘要： The present invention is a method of making an acceleration sensor chip. The sensor chip is prepared from a SOI wafer having a silicon substrate, a SiO2 layer and a silicon thin film. A dopant is ion implanted at a position corresponding to a semiconductor strain gauge on the silicon thin film to form a diffusion resistor, and for forming devices necessary for circuit construction on said silicon thin film. A protective film is provided on the entire surface of the wafer, and a plurality of through holes penetrating the silicon thin film are formed by patterning and etching to make a weight part and a beam part connected to a support frame part on the periphery. The SiO2 layer under the weight part and the beam part is removed by wet etching to form the through holes, while leaving the protective film in place. The protective film is removed and a resist coated over the entire surface of the wafer. A slit for dividing the chip is formed part way through the wafer by dicing. The resist is removed by ashing with an O2 plasma and the chip is divided by concentrating a stress on the slit.

摘要： An apparatus and method for controlling damping force characteristics of shock absorbers independently of one another, the damping force coefficient for each shock absorber being controlled on the basis of so-called "sky hook" theory with respective sprung mass vertical velocities and relative velocities between the sprung mass and unsprung mass taken into consideration. The relative velocity detecting sensors are only installed on portions of the vehicle related to front left and right tire wheels. The road surface velocities on the front left and right tire wheels are calculated and the road surface velocities on the rear left and right tire wheels are calculated on the basis of the calculated front left and right wheel road surface velocities, a vehicular wheel base length, and a vehicle speed. Then, relative velocities between the sprung mass and unsprung mass related to the rear left and right tire wheels are calculated on the basis of the calculated rear left and right tire wheel road surface velocities and sprung mass vertical velocities related to the vicinities of the rear left and right tire wheels.

摘要： A member is prepared by forming a magnetic surface layer on a magnetic base member having a different composition from the surface layer. A laser beam is radiated onto the member so as to fuse the member and the surface layer, thereby forming a fused portion having magnetic properties. A modified portion is formed in a portion of the fused portion corresponding to the surface layer such that this portion has different permeability from other portions of the surface layer.

摘要： A suspension control system is designed to adjust suspension characteristics between hard and soft for bounding and rebounding stroke independently of each other. The system has a sensor means for monitoring speed of a vehicular body as a sprung mass for producing a vehicle body speed indicative signal, which vehicle body speed indicative signal has a variable signal polarity depending upon the direction of vibration, and a sensor means for monitoring relative speed between the vehicular body and a vehicular wheel as an unsprung mass for producing a relative speed indicative signal which also has a variable signal polarity depending upon the direction of relative movement of the vehicular body and the vehicular wheel. A control unit detects a combination of signal polarities of the vehicle body speed indicative signal and the relative speed indicative signal for adjusting damping characteristics for bounding and rebounding vibration independently of each other and depending on the detected combination.
