A liquid discharge device includes a liquid discharge head including nozzles configured to discharge a liquid, a carriage mounting the liquid discharge head and movable, a wiper configured to wipe a nozzle surface of the liquid discharge head, and a wiper mover configured to hold and move the wiper between a facing position at which the wiper faces the nozzle surface and a standby position at which the wiper does not face the nozzle surface. The carriage movably holds the liquid discharge head and the wiper mover as a single unit.

A mobile information terminal has: an operating position detecting part 37 that detects an operating position of a user on the basis of an output of an electrostatic capacitance sensor 30 that includes a thin film having a plurality of electrodes and detects an electrostatic capacitance of each of the electrodes; a direction input control part 31 that senses movement of the operating position on the basis of an output of the operating position detecting part, and generates a direction input signal; a key input part 32 that detects a pressing operation of the user on a pressing face of an operation key, and generates a key input signal; a display 22 having a display screen; and a display control part 34 that controls a display position of image information in the display screen on the basis of the direction input signal. A part of the thin film of the electrostatic capacitance sensor 30 is formed with overlapping with at least a part of the pressing face of the operation key, and upon sensing of the movement of the operating position, the direction input control part 31 determines whether or not to generate the direction input signal on the basis of an operating position upon start of the movement. Upon operation of the operation key that is arranged with overlapping with an electrostatic pad, a direction input for moving a screen display can be suppressed from being erroneously provided.

A semiconductor light-emitting device has a semiconductor light-emitting element for emitting light with emission wavelengths of 390 to 420 nm, wherein the wavelengths of light from the semiconductor light-emitting element are converted by a fluorescent substance having a monochromatic emission peak. The emission wavelengths of 390 to 420 nm, which have almost no adverse effect on human bodies and components of the semiconductor light-emitting device, are in a low human visibility range. Since light whose wavelengths are converted by the fluorescent substance are hardly affected by direct light from the semiconductor light-emitting element, light from the fluorescent substance has a favorable color tone. Also, the semiconductor light-emitting device allows desired luminous colors to be obtained only by changing fluorescent substance materials without changing the structure of the semiconductor light-emitting device or the semiconductor light-emitting element.
摘要:
An anti-acharan sulfate antibody, a hybridoma that produces the antibody, a detection method and a detection kit to which the antibody is applied are disclosed. The anti-acharan sulfate antibody can be produced by immunizing a mammal using as an antigen a substance obtained by chemically bonding a protein to acharan sulfate.
摘要:
An acid addition salt of a carba-sugar amine derivative represented by the following formula (1): wherein R1 and R2 each independently represents a hydrogen atom, or an alkyl group, an alkenyl group, an alkynyl group, an acyl group, an aryl group or an aralkyl group which may have one or at least two of the following substituent (I) or (II), or R1 and R2 are taken together to represent a substituent (III) (R8 to R12 each independently represents an alkyl group, an alkenyl group, an alkynyl group, an acyl group, an aryl group or an aralkyl group), with the proviso that both R1 and R2 are not a hydrogen atom at the same time; R3, R4 and R7 each independently represents a hydroxyl group or a hydroxyl group having a substituent; and R5 and R6 each independently represents a hydrogen atom, or a hydroxyl group or a hydroxyl group having a substituent, with the proviso that when one of R5 and R6 is a hydrogen atom, the other is a hydroxyl group or a hydroxyl group having a substituent.
摘要:
A connection adapter includes first interfaces, second interfaces for connection to communication devices connected to a radio packet communication network, and a conversion circuit performing mutual conversion between an input/output signal from or to high-level equipment and an input/output signal from or to the communication device. The conversion circuit receives or supplies from or to the high-level equipment a signal simulating the communication device connectable to the high-level equipment and receives or supplies from or to the communication device a signal simulating the high-level equipment connectable to the communication device.

A sludge concentrating apparatus comprising a sludge tank for storing sludge and a filter cloth having a shape of endless belt which turns between upper and lower rollers, further comprising filtering means of which at least the lowermost of rollers is immersed in the sludge, washing means of the filter cloth, and a filtrate chamber having a filtrate introducing port in contact with the filter cloth and a weir, wherein a sludge distributing tank serving as sludge introducing means into the sludge tank is provided near the upper end of the filtrate introducing port, and a concetrated sludge discharge tank serving as concertrated sludge introducing means with the filter cloth in between; said sludge concentrating apparatus further comprising coagulant adding means for adding an acid, and a flow adjustment device serving as a sludge uniform feeding means which feeds sludge fed into the sludge tank uniformly in the width direction of the filter cloth. It is thus possible to efficiently concentrate sludge produced in a sewage disposal plant in a large quantity without depending upon properties of sludge.
