CONSTITUTION: On a semiconductor substrate 21, a first gate oxide layer 22, an n<+> -polycrystalline silicon layer 23, and a fire-proof metal layer 24 are formed. The n<+> -polycrystalline silicon layer 23 and the fire-proof metal layer 24 are etched to form a polycrystalline silicon gate. Here, etching is made so that the first gate oxide layer 22 is exposed, and n<-> -impurity ions are implanted to form an n<-> -LDD25. The second n<+> -polycrystalline a silicon layer 26 and a second oxide layer 27 are, vapor-deposited over the entire surface for patterning. A formed oxide layer 27 is left out as a spacer, so that the polycrystalline silicon gate is in an inverted T-shape. The n<+> -polycrystalline silicon layer 26 on the upper part of the polycrystalline silicon gate is removed by etching, and n<+> -ion is implanted for formation of a desired field effect transistor.

Abstract: PURPOSE:To fix an armature having no bridge part using only adapter by providing an outer hub with an outside fixing part to fix an outer peripheral part of the armature and an inside fixing part to fix its inner peripheral part, and bending the inside fixing part inward at proper spots. CONSTITUTION:An outer hub is provided with a convex part 13a to fix an outside pole 5b of an armature 5 and a protruding part 13c to fix its inside pole 5a. The armature 5 which has only an outer hub 13 and magnetic cutting off holes 10 formed over its whole periphery can therefore be used without increasing the number of parts. Thus, since a bridge part can be omitted, magnetic leakage from the bridge part does not occur, and magnetic performance can accordingly be improved. In addition to that, since the armature 5 is fixed only by the outer hub 13, the vibration of an inner hub 11 can be controlled to more reduce noise due to operation in comparison with a case where other members are used.

Filed: 1981-02-04
Abstract: PURPOSE:To optimize a control, by adding fixed input components, which are generated by reducing a set value signal in a ratio setting equipment, and adjustment input components, which are generated by reducing the adjustment signal from an adjusting part in a ratio setting equipment, to make an operation input quantity. CONSTITUTION:The control quantity of a process detected by a detector is converted by an adjusting converter and is transmitted to a comparing part. A deviation signal (e) between a set value B and a feedback signal is converted to such adjustment signal y1 by an adjusting part that a good control result is obtained in the whole of the system. The set value B is transmitted to a ratio setting equipment and is converted to y2=beta.B by a ratio constant beta(beta=0-1). Adjustment input components A is reduced to A=alpha.y1 by multiplying the adjustment signal y1 by a ratio constant alpha. The input of an operating part becomes y=alpha.y1 +y2. Thus, a narrower proportional band is set, and the response to disturbance is accelerated by increment of a proportional gain, and further, a system characterized by increment of stability of the system, reduction of change of the process gain, and less offset is constituted easily.

Title: Manufacture of chelate resin
Inventor: MATSUDA KIMIAKI
IPC: C08F8/30
Filed: 1987-01-23
Abstract: PURPOSE:To produce a chelate resin having a superior adsorption capacity, by reacting a specific functional group-containing resin with hydroxylamine. CONSTITUTION:A resin having functional groups of the formula (where R is an amino or its derivative) is reacted with hydroxylamine to yield the intended chelate resin. The reactant ratio of the resin having functional groups of the formula to hydroxylamine is such that about 0.25mol. or more of hydroxylamine is used per mole of the functional group of the formula in the resin. Since the use of more than the required amount of the reactant requires a recovering process after the reaction, which makes the process complicated, preferably about 0.5-5mol. of hydroxylamine per mole of the functional group of the formula in the resin is used. A decrease in the proportion of hydroxylamine below about 0.25mol. is undesirable, becaure it leads to a decreases in the amount of the introduction of chelate-forming functional groups, which lowers the metal adsorption capacity of the resulting chelate resin.

Title: Multistage column switching elution method
Inventor: SHIMIZU TOSHIYUKI
IPC: G01N30/46
Filed: 1986-01-28
Abstract: PURPOSE:To shorten the measurement time of fast liquid chromatography by using a solvent with fixed composition by paying attention to the fact that a component having a long holding time is solved out faster and faster as the length of a column is made selectively shorter and shorter during analysis. CONSTITUTION:An eluate consisting of fixed components is admitted into the 1st column 1 from an injector 6 at a constant flow rate through the operation of a pump 5 for injection. The 2nd column 2 and a hexagonal valve 7, on the other hand, are so connected that a the column 2 can be put in and out of an elution passage 4 at any time. Namely, when the valve 7 is as shown in figure, the column 2 is put in the elution passage 4 and when the valve 7 is switched, the column 2 is taken out of the elution passage 4 and the column 1 is connected directly; to a detection part 3. This constitution is employed to switch the valve 7 at a proper point of time and take the valve 2 out of the elution passage 4, thereby shortening the substantial column length. Consequently, the time required for measuring all components can be shortened.
