Abstract: In a microcatheter, a shaft tube thereof is sectioned into a proximal zone, an intermediate zone, and a distal zone from a connector to the forward end thereof, each being formed of a multilayered tube, including three types of multilayered tubes different in hardness, an inner layer extending along all the zones from the proximal zone to the distal zone of the shaft tube, and a reinforcing material being fitted to the outer circumference of the inner layer, a first outer layer extending along all the zones from the proximal zone to the distal zone of the shaft tube so as to coat, and adhere to, the inner layer and the reinforcing material, to form a base layer structure of the inner layer/reinforcing material/first outer layer, a third outer layer coating the first outer layer of the base layer structure in the proximal zone, a second outer layer coating the first outer layer of the base layer structure in the intermediate zone.

Abstract: In an inkjet recording device, nozzles are arranged orthogonally to a deflection direction of deflection electrodes. Ink jetted from each nozzle is charged by a pair of charging electrodes. Charged droplets are deflected by an electric field formed thereby. Voltages applied to each electrode and timings thereof can be independently adjusted.

Abstract: There is provided a wavelength variable light source system capable of changing wavelength and intensity of output signal light and of improving preset accuracy and stability of the wavelength and strength of the output signal light. The system determines the both or either one of a target value for controlling wavelength and a target value for controlling intensity of output signal light of a wavelength variable light source by correlating a combination of the target wavelength and the target light output intensity specified from a higher-level device and controls operation states of the wavelength variable light source so that output values of monitoring circuits for monitoring the operation state of the wavelength variable light source converge to the target values.

Abstract: A conventional ink jet recording device has a phenomenon of such that a transverse pitch between longitudinal dot column of a first line and that of a second line of character lines to be printed becomes narrower than that between other longitudinal dot columns when printing out on a printing object traveling in high speed. Consequently, an ink jet recording device of the invention makes an interval between ink droplets on the longitudinal dot column of the first line and those on the longitudinal dot column of the second line longer than an interval between the ink droplets on the longitudinal dot column of a subsequent line following the second line.

Abstract: The present invention relates to a FIFO (First In First Out) memory control circuit for controlling FIFO memory which is used in various electronic devices. Specifically, the present invention relates to a FIFO memory control circuit capable of performing asynchronous read/write control hen a write clock and a read clock are different and it is known or determined which of these clocks has a higher clock frequency.

Abstract: A FIFO memory control circuit includes: a write address circuit for generating a write address which is an operation address; a read address circuit for generating a read address which is another operation address; a memory which receives a write permission signal, a read permission signal, a write clock signal, and a read clock signal and which has a memory capacity of a predetermined number of words, wherein, while the write permission signal is asserted, data is written into an address in the memory designated by the write address in synchronization with the write clock signal, and while the read permission signal is asserted, data is read from an address in the memory designated by the read address in synchronization with the read clock signal: a first count control enable signal generation circuit for generating a first count control enable signal based on a first clock signal and a least significant bit of a said operation address corresponding to a second clock signal, the first clock signal being one

Abstract: A video signal conversion device of the present includes a flicker reduction section including a plurality of line buffers for storing data in accordance with an address thereof. The flicker reduction section receives non-interlaced signals, converts the non-interlaced signals to interlaced signals and performs a flicker reduction process.

Abstract: A power plant is mounted on both sides in a transverse direction by mounts. Each of the mounts is placed within a triangle defined by a point on a primary inertial axis of the power plant on the transverse side of the power plant, a point at a node of power plant bending vibrations in a twisting mode or in a fluctuation mode, and a point defined by the intersection of a perpendicular line passing through the primary inertial axis and a horizontal line passing through the node of vibrations.

Abstract: A belt-pulley drive mechanism comprising a pulley having a plurality of circumferentially extending grooves of V-shaped cross-sectional configuration, a belt adapted to be passed around the pulley and stretched under tension so that the belt is engaged with the pulley in torque transmitting relationship, the belt being formed with a plurality of longitudinally extending ridges of V-shaped cross-sectional configuration which are adapted to be engaged with the grooves in the pulley when the tension is applied to the belt. The grooves or the ridges or both are formed in a cross-section along a concave line so that a clearance is formed between the pulley and the belt when the tension is removed from the belt, the clearance being larger at a transversely central portion than at side edge portions.
