(Purpose) A construction for mounting a load-sensing element for use with a vehicle, in which construction no measurement error is resulted even if the slide plate contacts the leaf spring at different contacting points. (Construction) The sensing element 21 is composed of opposed walls forming a substantially U-shape in both front and side views thereof and having a hollow portion therein, and a plate-like member made of a magnetic material, which plate-like member being inserted into the hollow portion and threaded by a coil to be held therein, wherein the mounting location 15f of the slide plate 15 is a groove into which said sensing element 21 is fitted; wherein the construction further includes a lid which fits over the sensing element and a wedge-like key inserted under the sensing element for fixing the sensing element. The output of the sensing elements are added together so as to output a sum of the outputs of the sensing elements.

A disk array device selects a redundant generation method for reducing the overhead and improving the reliability associated with generating redundant data. The disk array device includes a disk controller connected to and controlling an array of disk drives. The disk controller includes a redundant data generator, a difference data generator, and a redundant data generation method selector. The redundant data generator is able to generate redundant data via a read and modify method and an all stripes method. The disk array device selects a method of generating redundant data from a method of read and modify and all stripes, and a method of generation in a drive and a method of difference, both of which are executed to generate redundant data on a disk drive. The disk array device selects the method of generating redundant data that will minimize the time required to process, transfer and store both the received host data and the generated redundant data based on the length of write data received from the host, an access pattern specified by the host, by the current load state of the disk drives, and by the existence of a failure state in a disk drive. Divided write data and previous data to be updated may be transferred depending on the write data length.

Power consumption of an LSI chip is estimated at the beginning stage of the designing without using the HDL description. An I/O part power of a new designing LSI chip is calculated by an equation with using the outside specifications required by the application of the LSI chip. An I/O part power of an original LSI chip is calculated by the outside specifications, the core circuitry part power of the original LSI chip is calculated by subtracting this calculated I/O part power of the original LSI chip from the known total power of the original LSI chip, and converting the voltage and process and frequency, the core circuitry part power of the new designing LSI chip is calculated. The kinds of functions, voltage, frequency, the number of gates, unit capacity and clock structure of the new designing LSI chip are given and referring to the data base of ratio of each function described the ratio of the number of FF and the ratio of clock power/logic power, the clock system power is calculated by the number of FF and the clock structure. The logic system power is calculated by the ratio of the clock power/the logic power. The modifiable circuitry part power is calculated by summing up the I/O part power, the core circuitry part power, the clock system power and the logic system power.

A structure for attaching a sensing element for measuring load on a vehicle to a slide plate can reduce the number of components and gives good detection sensitivity. Mounting holes are made at an angle of about 20.degree. at both ends of an internal curved surface of the slide plate. Sensing elements each is secured in each the mounting holes. A wiring plate is placed centrally on a concave portion of the internal curved surface of said slide plate and is used to integrate lead wires from the sensing elements and extend them externally. The wiring plate and lead wires are molded.
