Title: Vibration detection sensor
Inventor: NAKATSUKA HISAYOSHI
IPC: G01H11/02
Filed: 1984-12-25
Abstract: PURPOSE:To obtain a vibration detection sensor detecting minute vibration with low frequency, by converting mechanical vibration to an electric signal by using a magnetical detection means. CONSTITUTION:The title detection sensor has a moving magnet type pick-up structure wherein an inertia wt. 2 is attached to the leading end of a cantilever 1 in a travelling state and a magnet 3 is fixed to the base end of said cantilever 1. A power generation system is constituted by arranging a magnet 3 so as to position the same inside a pair of yokes 8 around which dynamo coils 7 are wound. The whole of thus constituted electromechanical signal converter is shielded and the shield body 9 is clamped to the base parts of the yokes 8 and fixed to a vibrator 17 in a contacted state. By this constitution, voltage is induced in the dynamo coils 7 and vibration can be accurately detected. When impact vibration is present in a low frequency range of 100 Hz, by increasing or decreasing the mass of the inertia wt., the resonance frequency can be allowed to coincide with impact vibration frequency and higher sensitivity capacity can be obtained.

Title: Layout method for semiconductor chip and its device
Inventor: TONO KAORU
IPC: H01L21/822
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To enable miniaturization of semiconductor chips, and lower the cost by eliminating waste in power supply wiring and ground wiring. SOLUTION: A circuit-block layout means 6 specifies a circuit block of large power dissipation, based on a power dissipation value stored in a storage means 4 and arranges the specified circuit block closer to a power supply wiring and the ground wiring of a trunk line. A wiring width optimizing means 8 optimizes the widths of the power supply wring, the ground wiring of the trunk line, the widths of the power supply wiring and the ground wiring which connects the specified circuit block on the basis of the power dissipation value stored by the storage means 4. Therefore it is not necessary to add other auxiliary wirings to the circuit block of large power dissipation or using wasteful wirings by the standard wiring width for the circuit block of small power dissipation, thus eliminating these.
