Title: Arrangement construction of piles
Inventor: KIMURA TAKUMI
IPC: E02D27/16
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To reduce stress of piles at an earthquake by arranging shearing force bearing piles only supporting horizontal force on the further outside of piles corresponding to the outer circumferential corner parts of an upper structure within a pile group transmitting force to the ground. SOLUTION: The weight of an upper building 1 is supported with a pile 3 group through a foundation 2. When the piles 3 are arranged in this way, maximum shearing stress is generated in the piles 3a on the four corners by horizontal force at an earthquake. For reducing the stress, shearing force bearing pipes 4 supporting only horizontal force are arranged outside the piles 3a. Since the piles 4 are deformed to absorb earthquake energy at a big earthquake, the piles 4 function as energy absorbing piles. Accordingly, damage of the other pile 3 group is restrained to minimum. Particularly, even if the piles 4 are deformed by a big earthquake, influence on the supporting performance of the building can be minimized, and increase of cost can be restrained to minimum.

Title: Voltage generating circuit for liquid crystal display device
Inventor: OZAWA RYOJI
IPC: G02F1/133
Filed: 1987-04-27
Abstract: PURPOSE:To control the contrast in a certain voltage range even if the driving voltage of a liquid crystal panel is varied, by operating a contrast control function and a function, which corrects the variance of the driving voltage of the liquid crystal panel, independently of each other. CONSTITUTION:A circuit is so constituted that voltage application for contrast control and voltage application for correction of the variance of the driving voltage of the liquid crystal panel are controlled independently of each other. That is, the value obtained by adding the voltage to the ground of a variable resistance 3 and the plus voltage of a driving voltage control terminal 4 as a minus voltage is outputted to the output of an OP amplifier 1. If the gain of the OP amplifier is controlled, an optimum voltage can be applied to liquid crystal panels different in driving voltage. Since a voltage Vcc of the control terminal 4 is independently controlled if the variable resistance 3 is controlled to apply an optimum voltage, an optimum contrast is always kept even if the driving voltage of the liquid crystal panel is varied.
