The present invention aims to provide an apparatus capable of determining whether or not content is permitted to be taken out, by managing contents permitted to be taken out. One aspect of the invention is characterized by comprising: a storage means that stores therein taking-out-permitted-content identification data which is data generated on the basis of a part or entirety of each content permitted to be taken out; and a generating means that generates the taking-out-permitted-content identification data. Another aspect of the present invention is characterized by comprising: a storage means that stores therein taking-out-permitted-content identification data which is data generated on the basis of a part or entirety of each content permitted to be taken out to the outside; and an approving means that determines whether a content is permitted to be taken out, with reference to the taking-out-permitted-content identification data.
摘要:
A light-emitting device includes a light-emitting diode, a red light-emitting phosphor layer, a yellow light-emitting phosphor layer, and a blue light-emitting phosphor layer. These layers are stacked in the stacking sequence of the yellow, blue, and red phosphor layers in order of increasing distance from the LED. The stacking sequence of the yellow and blue phosphor layers is first determined in such a manner that these layers do not interact with each other. The stacking sequence of the red and yellow phosphor layers and the stacking sequence of the red and blue phosphor layers are determined by the discriminant D. This determination of the stacking sequence suppresses a reduction in the conversion efficiency of the phosphors due to concentration quenching, improving the emission efficiency of the light-emitting device.
摘要:
An A/D conversion circuit including a plurality of resistor elements connected in series between a low-potential power supply and a high-potential power supply. The A/D conversion circuit includes a plurality of comparators that compare a reference voltage divided by each of the resistor elements with an analog input voltage, the comparators having a sample-and-hold function for holding a sampled analog input voltage. The plurality of comparators also include a high-order bit comparator and a low-order bit comparator having different sampling sources. The high-order bit comparator may be configured to compare the analog input voltage and one of the reference voltages to obtain a determination result. The low-order bit comparator may old the analog voltage from the time that the low-order bit comparator retrieves the analog input voltage until the low-order bit comparator performs comparison.

摘要:
A cartridge detachable from a printer has a roll paper unit including roll paper, a roller, and flanges, and a separation member used to pull out the roll paper from the roll paper unit. Upon rotating the roll paper unit in a direction to feed out the roll paper, the roll paper is brought into contact with the separation member, thereby pulling out the roll paper from the roll paper unit and feeding out the roll paper to outside the cartridge.

Provided is a fluid bearing device with a hub part having high molding precision and dimensional stability and capable of being produced at low cost. An annular gate (14) is formed at a portion of a cavity (15) corresponding to an outer peripheral edge portion of a lower end surface (10c1) of a flange part (10c), and a molten resin (P) is filled into the cavity (15) through the annular gate (14) to form a hub part (10) made of resin. The hub part (10) molded by the injection molding exhibits a radial resin orientation through an entire periphery thereof. Further, an annular gate trace (16) is formed at the outer peripheral edge portion of the lower end surface (10c1) of the flange part (10c) of the hub part (10).

It is an object to improve bearing rigidity in a thrust direction at high temperatures and reduce a torque at low temperatures. An axial member is arranged in such a manner that an outer circumferential surface of an axial part is opposed to an inner circumferential surface of a bearing sleeve with a radial bearing gap interposed therebetween, and both end faces of a flange part are opposed to one end face of the bearing sleeve and a bottom face of a housing with thrust bearing gaps interposed therebetween, respectively. In this manner, the axial member is supported by dynamic pressures generated in the respective bearing gaps in the thrust direction in a non-contact manner. The flange part of the axial member is formed of a resin in such a manner that its linear expansion coefficient in its axial direction is equal to or larger than that of the housing.

The present invention easily provides a compact recording apparatus including a paper chamber capable of containing paper and a ribbon chamber containing an ink ribbon in a manner such that the ink ribbon on a supply shaft can be taken up onto a take-up shaft, by utilizing the dead spaces in the paper chamber and the ribbon chamber. The distance between the paper chamber and the rotation center of the take-up shaft is larger than the radius of a ribbon take-up portion of the take-up shaft and is smaller than the radius of a fully taken up roll of the ink ribbon.
