摘要： An objective is to obtain a high robust position controller and a controlling method therefor, with respect to their technique in which control gain, in order to prevent an overshoot due to frictions, is most suitably adjusted. The position controller having a feedforward system includes: a friction-coefficient-estimated-value setting unit for setting arbitrary friction-coefficient-estimated-values; an overshoot-prevention-gain calculator for determining speed-integral-term feedforward gain, based on estimated friction-coefficient values set by the friction-coefficient-estimated-value setting unit; and a speed feedforward multiplying unit for calculating the product of the speed-integral-term feedforward gain multiplied by a feedforward command value that is based on a positional command; the multiplication product from the speed feedforward multiplying unit being used to reduce the feedforward term.

摘要： A recording apparatus of the present invention includes a head 21 having a plurality of nozzle groups (21A to 21C), and each nozzle group has a plurality of nozzles that are arranged with a predetermined nozzle pitch (k·D). The recording apparatus forms dots on a medium by repeating alternately an ejection operation in which a liquid is ejected from the nozzles and a carry operation in which the medium is carried using a predetermined carry amount F with respect to the head, and the distance between two nozzles that eject ink adjacently and that belong to different nozzle groups (the distance between #4A and #1B) is equal to the sum of an integral multiple of the carry amount and the predetermined nozzle pitch (F·α+k·D).

摘要： When a relatively large image in the sub-scanning direction is to be printed, a relatively large number of dot-forming elements among a plurality of dot-forming elements are used to form dots by means of sub-scanning with a relatively large average feed. When a relatively small image in the sub-scanning direction is to be printed multiple times at different positions in the sub-scanning direction on the same print medium, a relatively small number of dot-forming elements among the plurality of dot-forming elements are used to form dots by means of sub-scanning with a relatively low average feed. With this embodiment, large images are rapidly printed, and small images are printed more efficiently on printing paper.

摘要： A fluorescent lamp includes: a bulb including bent and straight-tube portions having an external tube diameter of 12 to 20 mm and a tube length of 800 to 2500 mm. The straight portions are disposed generally within the same plane through the bent portions. A pair of end portions with electrodes sealed therein form a single discharge path through the straight tube and bent portions. A phosphor layer is formed on the inner face of the bulb, and a discharge medium including mercury is sealed in the bulb. Thermal deterioration of the phosphor layer formed at the straight tube portions is reduced so deterioration of the initial light flux is suppressed, allowing lighting at higher efficiency. With the above configuration, a fluorescent lamp is compact and capable of light with high efficiency, and with improved light output properties. A light fixture uses this fluorescent lamp.

摘要： A multi-ringed fluorescent lamp includes a multi-ringed bulb, a phosphor layer formed on an inner surface of the bulb, a pair of electrodes and discharge medium with which the bulb is filled. The bulb includes ring bulbs in each of which straight portions and bent portions are placed alternately on a same plane, by bending partially a glass tube having an outside diameter of 12-20 mm into a rectangular shape, so that opposite ends of the tube terminate with the adjacent straight portions. The ring bulbs are placed concentrically on the same plane and connected through a bridge connection portion to form a single discharge path. A gap between adjacent bent portions is larger than a gap between adjacent straight tube portions and has a maximum value of 6-15 mm. The electrodes are provided in opposite ends of the discharge path of the multi-ringed bulb.
