Title: Manufacture of semiconductor element in which rear surface of wafer is polished by uv oversensitive tape
Inventor: CHIN SEIMIN
IPC: H01L21/301
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To avoid using other chemical substance for removing an UV-sensitive tape, etc., from a semiconductor wafer by removing the tape with irradiation of ultraviolet rays on the surface of the wafer by a new wafer back side polishing step. SOLUTION: An UV-sensible tape 35 is laid on the surface of a wafer 30 having an original thickness W1 with circuit elements mounted thereon, the back side of the wafer is polished, using a polisher 37 to reduce the thickness to W2, ultraviolet ray is applied to the tape laid on the polished wafer 30 and the tape is removed. Irradiating the ultraviolet ray on the tape activates a photo initiator to initiate a rapid photosetting reaction to lower the adhesion, thereby easily removing the tape from the wafer.

Title: Tip turbine driving device for engine with turbo
Inventor: ENDOU MAKOTO
IPC: F02B37/00
Filed: 1982-11-30
Abstract: PURPOSE:To dispense with a turbocharger as well as to economize in fuel consumption, by controlling the exhaust gas led into a surge tank in time of braking a car so as to be spouted to a tip turbine in time of high pressure load in a way of interlocking a computer. CONSTITUTION:When a car is applied with a brake, a solenoid valve 26 opens by a signal out of a computer 27 whereby suction pressure is led into a control cylinder 24, causing a selector valve 19 to take an A position, and exhaust gas is led into a surge tank 20 from a branch passage 17 and stored in the tank. In time of high load on a car, a solenoid on-off valve 22 opens by a signal out of the computer 27, then high pressure gas inside the surge tank 20 is led into a tip turbine 18 through a pressure feed pipe 21, rotating it coaxially together with a fan 14, and a pipe inside a casing 13 of an intercooler 12 is cooled so that supercharging air circulating inside this pipe is as well cooled. With this, a supercharging air drops in its temperature in consequence and simultaneously oxygen content per unit volume increases, meaning that suction air in an engine is cooled, thus an NO component in the exhaust gas decreases eventually.

IPC: C02F1/62
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To remove arsenic ions by a small amount of a treating agent in a wide pH range by a method in which an aqueous solution of a lanthanide element compound is added into raw water containing arsenic (V) ions to precipitate an arsenate of a lanthanide element, which is removed, and the concentration of residual arsenic (V) ions in the raw water is made less than a drainage standard. SOLUTION: An aqueous solution of a lanthanide element compound such as a chloride of a lanthanide element and a nitrate of a lanthanide element is added into raw water containing arsenic (V) ions to precipitate an arsenate of a lanthanide element, which is removed. In this way, the concentration of residual arsenic (V) ions in the raw water is made less than a drainage standard. Since it is effective in a neutral pH range, discharge without regulating the pH of the raw water after the removal of arsenic (V) ions is made possible. Besides, by treating the removed arsenate of a lanthanide element with an alkali solution, arsenic (V) can be separated in a concentrated form and the recycle of the recovered lanthanide element is made possible.
