Title: Semiconductor device
Inventor: KAZAMA ATSUSHI
IPC: H01L21/60
Filed: 2000-01-28
Abstract: PROBLEM TO BE SOLVED: To prevent a semiconductor element or a wafer from warping or the interface layer with a layer insulation film, etc., from peeling due to thermal stresses of a re-wired layer in a semiconductor device of a small size nearly the size of the semiconductor element. SOLUTION: The re-wired layer uses as a main material a Cu composite alloy containing Cu2O having smaller linear expansion coefficient and a smaller modulus of elasticity than those of Cu simple substance at a ratio of 80 vol.% or less, thereby lowering the thermal stress of the re-wired layer. Thus, a semiconductor device can be realized wherein a semiconductor element or wafer hardly warps and peeling between layers hardly occurs.

Title: Water distribution control method and system for controlling child stations and water feeding
Inventor: KOSAKATANI JUICHI
IPC: H04Q9/00
Filed: 2000-02-25
Abstract: PROBLEM TO BE SOLVED: To easily and quickly control rapid fluctuations of the water level of a reservoir being controlled by each child station, without provision of a master station. SOLUTION: A plurality of reservoirs 5 are arranged in a distributing pipe network 7 which is branched and spread from an upstream side, and each child station 1 controlling the water level of the reservoir to implement stable water distribution is connected to the other child station 1 via a network 2. When a difference ΔH between the water level of this time and the water level of the last time exceeds an automatically controllable threshold value K (ΔH>K), a control mode selecting section 13 selects an assist requiring mode, then calculates a control float T required for reaching a full water-level/draughty water-level, and broadcasts an assist requirement inclusive of a child station number thereof and a time period (float) T to the network 2.  The other child station 1 which has received the assist request selects an assist mode when the abnormal station is on a downstream side, and refers to a controllable timer value Table which affects inflow amount variation of the abnormal station by the control of the received station per se. When Table > T is satisfied, automatic controlling conditions of the station are changed, to thereby carry out responsive control. When the number of child stations which can cope with the abnormal station is plural, a child station nearest to the abnormal station carries out the assist.
