Title: Method for recovering and removing emulsified heavy oil incorporated in seawater
Inventor: ISO SHIYUNYA
IPC: C02F1/24
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To efficiently recover and remove an emulsified heavy oil by eliminating the failure that the emulsified heavy oil can not be removed like petroleum even if the oil is taken together with sea water and left standing or treated by a centrifugal separator since the emulsified heavy oil is an emulsion formed by dispersing the heavy oil in water different from petroleum, and is easily dispersed in sea water. SOLUTION: A process (hereafter called a floating process) for supplying bubbles having 10-3,000μm average diameter to a seawater layer, in which the emulsified heavy oil is incorporated from the under part and adsorbing the emulsified heavy oil to the bubbles to float upward is performed and the resultant high concentration emulsified heavy oil is recovered and removed. The floating process is executed not only a sea area such as a harbor but a plant on land. Also the floating process is repeatingly executed until the heavy oil concentration remaining in the seawater reaches <=1ppm. At the time of reaching <=1ppm, a trace amount of the emulsified heavy oil is adsorbed in the absorbent and the seawater is discharged to a natural water system such as the sea.

IPC: G06F1/32
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of an electronic device in accordance with fining of the device with no complication of a circuit due to reduction of the number of gates by supplying a clock signal to the circuit constructing the electronic device only in its actual working timing. SOLUTION: A gate signal showing the real working timing of the memory block of a timer 10a which controls the operation of both circuits of the same working timing is generated for every block (memory block) consisting of an SRAM 12 and a RAM interface 11a which serve as the said circuits. Based on the gate signal, the supply of a clock signal is controlled to the memory block. Thus, the circuit power consumption due to driving of clock lines done in the SRAM 12 and the interface 11a is eliminated after the operations of these RAM 12 and interface 11a. As a result, the total power consumption is reduced for a digital IC which includes the SRAM 12 and the interface 11a.

Title: Pattern formation method and device
Inventor: CHOKAI MINORU
IPC: H01L21/027
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent, for example, an optical element and a coating film from being damaged by applying a beam where the pulse width of an excimer laser is longer than a specific value. SOLUTION: A beam where the pulse width of an excimer laser 1 is longer than 100 ns is applied. The oscillation life of the laser itself is extended. For example, the spiker/sustainer vibrating method is known as the method for extending pulses, and a pulse width exceeding 1 μs is achieved. More specifically, the pulse width can be drastically extended without using any additional optical system such as an optical system for splitting an optical path, thus extending the pulse width at least by 100 times as compared with a normal pulse width of 10 ns. Therefore, an energy density per unit time becomes much smaller, namely 1/10 or less, thus preventing an optical element and a coating film from being damaged. The electron density of discharge can be controlled by electron beams for extending life or the plasma cathode ionization method can be utilized.

Title: Temperature correspondence type fluid pressure control valve
Inventor: SASAKI AKIRA
IPC: F16K31/70
Filed: 1985-04-15
Abstract: PURPOSE:To obtain a temperature correspondence type fluid pressure control valve which automatically performs pressure correction corresponding to the temperature variation by transmitting the variation of the fluid temperature to a valve piece by a bimetal and adjusting the opened port part of a valve port. CONSTITUTION:When the fluid temperature rises, the free edge of a bimetal 7 is curve- deformed downwardly, and a pressure adjusting pin 10 slides downward by the portion, and a valve piece 11 is pushed down, and the opening degree of a valve port 4 is reduced to lower the secondary-side pressure. Then, a pressure adjusting spring 5 extends to push up the valve piece 11, and pressure control in rivalry state is again carried out. In this case, the rivalry balance between the pressure in the valve and the springy force of the pressure adjusting spring 5 is varied by the portion corresponding to the variation rate of the curve-deformation of the bimetal 7, and as the temperature rises, constant control by a weak pressure value is carried out. On the contrary, when the fluid temperature lowers, the pressure adjusting pin 10 slides upward by the portion, and the opening degree of the valve port 4 spreads, and the secondary-side pressure increases. Therefore, the blowing-out flow-rate of fluid is kept at a constant value.
