Title: Sole component and footwear article comprising the component
Inventor: JIEEMUZU RATSUSERU
IPC: A43B13/14
Filed: 1992-04-15
Abstract: PURPOSE: To provide a sole member, which can make damage to knees as small as possible even after many hours of walking and eliminates disadvantages of conventional techniques, and a footwear product made of the member. CONSTITUTION: A sheet of an elastic material has an approximately longitudinally extending recess 2 having a divergent side wall 3 which, if a downward force exists, deflects it horizontally. The recess 2 extends outward toward the part of the front part of the foot on one side from a heel region 2a imparting a low-pressure region below the calcaneus. The center of gravity of the user is diffused sideways and outwards during the stage of the stance of a stepping cycle. Thereby the tendency to turn inward in excess is decreased. The recess 2 terminates at the proximal head of the fifth phalanx and produces the low-pressure region relative to the head of the first phalanx, thus making it easier to turn outward again at toeing-off.

Title: Output control for snowfall detecting device
Inventor: SAEKI SHINICHI
IPC: G01N27/00
Filed: 1994-05-09
Abstract: PURPOSE:To effectively utilize a snow melting device to reduce wasteful energy consumption and attain more effective remaining snow disposal by providing a snowfall detecting device with an up-down counter, and counting a clock pulse by means of this counter. CONSTITUTION:In a time zone from an A point to a B point, there is not snowfall, a numerical value of a counter is in a state of zero, and the counter is not operated. Next, when snowfall is detected at the B point, counting is started as an up-counter. From this time point, the numerical value of the counter is added with pulses, is no more zero, and therefore, is outputted and a snow melting device is operated. Then, at a C point about 20 minutes after the B point, snow stops falling and snowfall can not be detected, thus making the numerical count value become 1200. Thereafter, down counting is performed and the snow melting device is operated with a remaining snow disposal time while the numerical value of the counter is being reduced. After that, arriving at a D point about 20 minutes after the C point, the counter is stopped to cut off the output at the time point of the numerical value becoming zero.

Title: Controlling method and controlling mechanism of vehicle steering system
Inventor: HACKL MATTHIAS
IPC: B62D6/00
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a controlling method and a controlling mechanism of a steering system in which appropriate steering intervention is made as necessary. SOLUTION: A steering system is provided with a steerable wheel, an actuator, and a superimposed transmission, which produces the steering operation of the wheel by superposing an additive steering operation, which is produced by the actuator, on the steering operation performed by a driver. In a controlling system, which controls the actuator of such a steering system, μ-split braking is recognized by means of a recognition stage 62, based on both a difference Δp between car braking pressure Pvr and Pvl in both front wheels of the car and the operation of a switch 63 of a brake lamp.  When the braking is recognized as μ-split braking, a switch 615 is turned on by a signal S, and a target value δMsoll of the additive steering angle is formed, based on both yaw-angular velocity ω corresponding to a yaw-quantity detected by a sensor 26 and a target value ωsoll of the ω, which corresponds to the target value set by a target value setting device. Thus, appropriate steering intervention can be made as occation demands by regulating the additive steering angle, which is supplied from the actuator to the superimposed transmission, according to the target value δMsoll.
