Abstract:
The present invention provides a reinforcing bar material coated with a high adhesion anticorrosion film that enables to increase adhesion strength to concrete, which comprises forming two layers of anticorrosion films on a surface of a reinforcing bar material by means of spraying an epoxy powder coating material under a temperature condition where performance of the epoxy resin can be retained, so as to solve a pin hole problem that inevitably occurs in an anticorrosion film, and also to exhibit firm projections in a state coated with the epoxy resin on the second layer of anticorrosion film.The present invention comprises heating a reinforcing bar material, spraying and melt-adhering an epoxy powder coating material onto the reinforcing bar material while a temperature on a surface of the reinforcing bar material is between 200 and 250° C. so as to form a first anticorrosion film, and also, under this temperature condition, spraying and melt-adhering an epoxy powder coating material with acrylic resin beads having a particle diameter 2.5 to 3 times that of the epoxy resin powder mixed in on a surface of the first anticorrosion film in a molten state so as to form a second anticorrosion film, followed by cooling the reinforcing bar material coated with the first and second anticorrosion films to prepare the reinforcing bar material coated with a high adhesion anticorrosion film having countless projections formed by the second anticorrosion film.
Abstract:
A coated paper is white and glossy enough to give satisfaction as a printing paper, exhibits a good printability in offset sheet-fed printing and a high printing gloss, and does not degrade the print efficiency. The coated paper is characterized by having two or more coating layers composed mainly of a pigment and an adhesive on at least one side of a base paper. When ink is transferred onto the paper, the ink settability is relatively low in the early stage of the drying process and relatively high in the final stage.

A multifunction system has advanced functions and high speed capability and is excellent in expandability. The multifunction system includes a controller, an IIT, an IOT, and a light distributing device. For a print job, print data outputted from the controller is converted into optical signals, which enter a light distributing device and are transmitted to the IOT of the emission side. The IOT prints the received data onto a printer. For a copy job, copy data outputted from IIT is converted into optical signals, which enter the light distributing device, and are transmitted to the IOT of the emission side. For a scan job, scan data outputted from the scanner is converted into optical signals, which enter the light distributing device, and are transmitted to the controller of the emission side. The controller processes the received data.
Abstract:
A reception result of an analog signal transmitted from a local switch to a subscriber line, or a voltage difference corresponding to a line current is analyzed, and a transmission characteristic in the subscriber line is evaluated based on an analyzing result. The transmission characteristic is sent to a network by use of a function of an analog transmitting unit. Noises having power of a predetermined threshold value or more are detected from a data signal input to a digital transmitting unit, and a periodicity of the noises is examined, whereby influences of the cyclic noises are evaluated, and an examination result is sent to the network by use of the function of the analog transmitting unit. As a result, provided is an xDSL modem capable of automatically collecting various characteristics of the subscriber line connected thereto prior to a start of a provision of a broadband communication service.

The light-emission control section causes the plural light-emitting portions to periodically emit light in accordance with image data representing an image that is to be formed on the image-holding member, to form the image on the image-holding member. The light-emission control section varies a light-emission period during formation of the image, so as to correct for periodic fluctuations within the image of at least one of density and magnification ratio in the second direction.

A motor control apparatus includes an inverter circuit for supplying driving power to a motor, a motor current detector for detecting current flowing through the motor, an inverter controller for controlling the inverter circuit based on the output of the detector. The inverter controller has a setting unit for setting various command values to control motor driving status, and a processing unit for controlling the inverter circuit based on the setting on the setting unit. The setting unit sets command value so that a load angle which is an angle between rotor axis and motor applied voltage is operated on the smaller side of the angle that provides the maximum output torque in the load angle-output torque characteristics.

A driving apparatus of a plasma display panel includes a sustain generator section that sustains sustain electrodes at a specific potential (ground potential) and applies alternately a first positive pulse voltage and a first negative pulse voltage to scan electrodes, as a sustain pulse voltage, during a sustain period, and an address voltage generator that applies a voltage changing temporally to address electrodes. The address voltage generator applies a second pulse voltage with a predetermined polarity to the address electrode in synchronization with a pulse with the same polarity as the second pulse voltage out of sustain pulse voltages during the sustain period.

A reset pulse generating section applies the total of voltages of a positive voltage source and two constant-voltage sources from a high side ramp wave generating section to a high side scan switching device as the upper limit of a reset voltage pulse, and applies the ground potential from a low side ramp wave generating section to a low side scan switching device as the lower limit of the reset voltage pulse. A sustaining pulse generating section applies the upper and lower limits of a sustaining voltage pulse through a common sustaining pulse transmission path to the low side scan switching device.
Abstract:
Sustain electrodes (X1, X2, . . . ) of a PDP (20) are grounded. A PFC converter (40) converts an alternating voltage into a DC voltage (Vs) and applies it directly across a PDP driver (10). A sustaining pulse generating section (1) converts the DC voltage (Vs) into a primary voltage pulse (VF), and applies it across a primary winding (2a) of a transformer (2). The transformer (2) converts the primary voltage pulse (VF) into a sustaining voltage pulse (Vp), and applies it to scan electrodes (Y1, Y2, . . . ) of the PDP (20) through a reset/scanning pulse generating section (3). An inductor (L) is connected in parallel with a secondary winding (2b) of the transformer (2). The inductor (L) resonates with the panel capacitance of the PDP (20) at the rising and falling edges of the sustain voltage pulse (Vp).
Abstract:
The present invention provides a motor controller capable of driving a synchronous motor having no position sensor stably at high efficiency by carrying out simple control. In order to attain this purpose, a reactive current is obtained from a motor current and a rotation phase, an error voltage is obtained from the reactive current and the command value of the reactive current, thereby obtaining a motor applied voltage command value Va that is used to compensate for the V/f characteristic of the motor. Furthermore, the motor applied voltage command value Va is applied to an output command computing section, and computed with the rotation phase signal of a wave generation section, thereby obtaining a signal for PWM driving the switching devices of an inverter circuit.
