IPC: H01L21/308
Filed: 1985-11-18
Abstract: PURPOSE:To wet-etch of aromatic polyether amide by using a photo-resist employing a specific amide group copolymer as a main agent. CONSTITUTION:A solution of aromatic polyether amide is applied onto a substrate 1 and dried, thus forming a film 2 consisting of the aromatic polyether amide. A composition containing a copolymer of acrylamide and diacetone acrylamide and a sensitizer is applied onto the film 2, thus shaping a photo-resist film 3. Desired sections in the film 3 are irradiated by ultraviolet rays and irradiating sections are cured, and a pattern 4 is formed through development. The exposed film 2 is etched by a solvent (such as N-methyl-2-pyrolidone) dissolving the film 2, and the pattern 4 is peeled. According to said method, the pattern of aromatic polyether amide can be shaped through wet etching.

Title: Sensing apparatus of memory device provided with nand-type cell
Inventor: CHIYAN WAN HA
IPC: G11C17/18
Filed: 1992-09-28
Abstract: PURPOSE: To permit the potential of a column line and a reference line to be normal and to improve sensing speed by permitting current flowing the column line and the reference line to flow for a fixed time in the same level after an equalizing signal becomes low level. CONSTITUTION: Dummy lines 1 and 2 are connected to a column line dummy cell part 205 and a reference line dummy cell part 206. The potential of the dummy lines 1 and 2 is respectively changed, in accordance with the potential of an unselected row line and a selected row line. The potential of the dummy lines 1 and 2 is changed, and the equalizing signal becomes low. After that when the potential of the selected row line and the unselected row line is in a transitory state before it becomes a perfectly fixed value, the dummy lines 1 and 2 have the potential of the transitory state between 0.5V and 5V, so that the current flowing in the column line becomes almost equal in value to that of the current flowing in the reference line. Therefore, the potential difference between the column line and the reference line is widened normally, and the sensing speed is improved.

Abstract: PURPOSE:To aim at improvement air-fuel ratio control accuracy just after a drive range variation, by varying a reference correction value, controlling the reference value of air-fuel ratio control, gradually from value just before a variation to that just after the variation at a time when a drive range is varied. CONSTITUTION:A control circuit 20 reads the reference value of air-fuel ratio control to be outputted to a linear type solenoid valve 9, on the basis of each detected value out of a suction absolute pressure sensor 10 and a crank angle sensor 11, and it determines an air-fuel ratio correction value on the basis of the detected value of the oxygen sensor 14 when an air-fuel ratio feedback condition is effected. And, when the detected value of the oxygen sensor 14 is reversed, it calculates a reference for compensating an error in the reference value corresponding to a drive range and renews it. And, when this drive range is varied, it sets the value between the adjacent reference correction value and the newset reference correction value in the adjacent drive range as the reference correction value, thereby determining the air-fuel ratio control output value.

Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To aim at improvement of removing temp. change around control temp. for fluid by maintaining the quantity of leakage flow passing through a valve after the valve is first opened by a first thermal expandable element. SOLUTION: When the temp. of fluid with which a first thermal expandable element 3 is immersed continously reaches a certain threshold value, the element expands to thereby allows first opening to be performed. Next, a second thermal expandable element 6 is also immersed threrein. The thermal threshold value thereof is lower than that of the element 3, and thus the element 6 expands to thereby prevent a flog 2 from being in contact with a seat 5. In this way while the remaining opening is maintained in the case of opening a new valve a certain leakage flow quantity is led. The flow quantity is sufficient for maintaining the element 6 as it extends.
