Abstract:
It is to provide a thermodynamically and chemically stable dopant material which can achieve controls of the pn conduction types, carrier density, and threshold value of gate voltage, and a manufacturing method thereof. Further, it is to provide an actually operable semiconductor device such as a transistor with an excellent high-speed operability and high-integration characteristic. Provided is a dopant material obtained by depositing, on a carbon nanotube, a donor with a smaller ionization potential than an intrinsic work function of the carbon nanotube or an acceptor with a larger electron affinity than the intrinsic work function of the carbon nanotube. The ionization potential of the donor in vacuum is desired to be 6.4 eV or less, and the electron affinity of the acceptor in vacuum to be 2.3 eV or more.
Abstract:
To provide a pump dispenser with a trigger, having a simple construction, the number of parts reduced, and remarkably excellent operability. In a pump dispenser (1) which jets liquid in a cylinder (4g) from a nozzle portion (5) when a piston (7) integral with the nozzle portion (5) is pushed down according to grasping of a trigger (4c), the cylinder (4g) is integrally formed inside a barrel portion (4a) disposed along an axial direction of a container and the trigger (4c) is integrally formed on the barrel portion (4a) via a hinge portion (4b). Since the trigger is integrally formed on the cylindrical barrel portion disposed along the axial direction of the container via the hinge portion, a fulcrum for causing the trigger to pivot can be disposed as rearward as possible, so that a large leverage can be taken. Since at least the barrel portion and the trigger are integrally formed from synthetic resin, movement of the pivot fulcrum becomes remarkably accurate.
Abstract:
A drive circuit including circuitry that can be easily adjusted, the output drive current can be kept balanced, and high-precision drive current can be supplied to the load circuit. Clamp circuit 10 is furnished to hold the drain voltage of current output transistor QN12, which supplies drive current to a load resistor. When transistor QN12 is in a conducting state, drain voltage VA of transistor QN12 is held at approximately the same level as source voltage VD of transistor QN14 by clamp circuit 10. So rise and fall in the drain output current of transistor QN12 can be kept balanced, and rise and fall delay time can be made approximately equal for input signal Sin.
Abstract:
In a file, the TDEV mask data information including the TDEV mask data constituted by connecting a plurality of line segments and a calculation expression for forming the TDEV mask data, are stored in advance. A readout section reads out a predetermined TDEV mask data information from the file. A display section displays the line segment which is represented by the desired TDEV mask data information. An operating section inputs information for changing at least one of the start point and the characteristic value to the desired value with respect to the line segment to be represented by the desired TDEV mask data information. A TDEV mask data change section receives information inputted by the operating section and changes TDEV mask data ifnromation based on the calculation expression of the TDEV mask data information, and allows the display section to display the line segment represented by the changed TDEV mask data information.
Abstract:
A high resolution patterning method of a resist layer is disclosed by patternwise irradiation of a resist layer with electron beam utilizing a polysubstituted triphenylene compound as the electron beam resist material, which is graphitized and made insoluble in both polar and non-polar organic solvents for electron doses greater than 2×10−3 C/cm2, and which undergoes cleavage of the adduct chains and extensive de-aromatization of the triphenylene core therefore enhancing the solubility in polar solvents only for electron doses between 3×10−4 and 2×10−3 C/cm2. The thus formed positive or negative tone resist layer is highly resistant against dry etching to ensure the utility of the method in fine patterning work for the manufacture of semiconductor devices.

Abstract:
A unique method is proposed for fine patterning of a polymeric resin film on a substrate surface or fine patterning of the substrate surface with the patterned resin film as the resist. The method comprises the steps of: (a) forming a thin film of the resin on the substrate surface; (b) pressing the resin film pattern-wise under a pressure in a specified range by using, for example, a fine needle tip so as to enhance adhesion of the resin molecules to the substrate surface; and (c) dissolving away the resin film with an organic solvent selectively in the areas where the pressure is not applied in step (c) leaving the resin in a pattern-wise area after application of the pressure. The fineness of this patterning can be extremely high to be in the molecular size order.
Abstract:
A safety mechanism for a trigger activated dispenser which dispenses a pressurized fluid includes an engaging piece connected to an upper surface of a dispenser body by a hinge. The engaging piece, the dispenser body and the hinge are molded integrally from a plastic material and an engaging groove is formed on an upper surface of a nozzle cap to receive the engaging piece when the nozzle cap is rotated to an "Off" position. When the engaging piece is received in the engaging groove in the nozzle cap, the nozzle cap is locked in the "Off" state and the nozzle cap is prevented from being rotated to any position at which liquid can flow.
Abstract:
An automatic speed control apparatus for vehicles for controlling speed with good responsiveness and without delay at the start. An actuator opens and closes a throttle valve independently of an accel pedal, and a link connects the throttle valve and the actuator. A speed sensor detects the vehicle speed and a speed control mechanism controls the actuator so that the vehicle speed from the speed sensor is maintained at a predetermined speed. The amount of idle working of the actuator caused by the play of the link when the throttle valve is opened by the actuator is detected and the detected amount of idle working is added to the amount of control of the speed control mechanism as an amount of offset working in the direction in which the throttle valve is opened.
Abstract:
A constant-speed control device for a vehicle including a fuel cut device and a suspending device which suspends a fuel cut operation. An actuator is provided for controlling a throttle valve so that the vehicle runs at a constant speed. The fuel cut device carries out a fuel cut when the degree of opening of the throttle valve is smaller than a predetermined value. The suspending device suspends operation of the fuel cut device until the vehicle speed becomes higher than a target value by a predetermined value.
