Abstract: A twin-type reproducing apparatus with excellent usability and so forth is provided. Provided herein is a reproducing apparatus (1) having: a reproducing unit capable of reproducing two contents at the same time; two jog dials (21A, 21B) capable of performing a reproduction control of each of the two contents to be reproduced; a liquid crystal display (D) for displaying a content list of a plurality of contents stored in an inserted device; operators (41 to 44) for selecting contents to be reproduced and to be operated from the displayed content list, respectively; and operators (45, 46) for sorting the selected contents into two operation mechanisms. The result of the sort of the contents is displayed on the liquid crystal display (D).

Abstract: A marking device includes an ink jet printer (6) using an on-demand system. The printer (6) includes a body (18), a head (22), a slide table (24), a tray (26), an ink vessel (28), a solvent vessel (30), a pump (32) and a rest (34). The head (22) has a nozzle. The shortest distance between the tip of the nozzle and a golf ball (46) set into the tray (26) is equal to or greater than 0.2 mm. The ink vessel (28) is filled with an oil-based ink or an ultraviolet setting type ink. The ink is fed to the head (22) through a tube (48). The ink is discharged from the nozzle and is then moved to the surface of the golf ball (46). The solvent is supplied from the solvent vessel (30) toward the rest (34) through a tube (50) and the pump (32). When the printer (6) is stopped, the nozzle is immersed in the solvent of the rest (34).

Abstract: A playback apparatus is provided, which comprises a switch device (200) that gives the user good feeling of operating. A tape-shaped switch (500) is provided on a base part (410), extending along the circumference of the base part (410). A ring-shaped rotational drive section (450) opposes the tape-shaped switch (500) and can move to and from the base part (410). A plurality of second rollers (440), each having a roller part (444) made of rubber or the like, are rotatably mounted on the rotational drive section (450). A flange (313) continuously extending outward from the disc-shaped table plate (311) of a jog table unit (310) is mounted on the rotational drive section (450). When the user rotates the jog table unit (310), the rotation-detecting section (470) provided on the base part (410) detects the rotation of the unit (310).

Abstract: A tape-shaped switch (500) is provided on a base part (410). Coil springs (460) support a ring-shaped rotational drive section (450) on the position opposed to the switch (500), biasing the same away from the base part (410), so that the rotational drive section (450) may move toward and from the base part (410). First buffers are provided in association with the switches (501) of the tape-shaped switch (500), respectively. A flange (313) extends outward from the disc-shaped table plate (311) of a jog table unit (310) and is mounted on the rotational drive section (450). When the user depresses the jog table unit (310), moving the same downward, at least one of the switches (501) is closed. The motion of the jog table unit (310) is reliably detected because it is detected at a position outside that part of the jog table unit (310), which is depressed so that good feeling of the operation can be obtained.

Abstract: An epitaxial layer 12 is formed on a semiconductor substrate comprising silicon carbide, a Schottky electrode 14 is formed surface of the epitaxial layer 12, a noble metal contact electrode is formed on the Schottky electrode 14, and after the formation this contact electrode 15, heat treatment is conducted at a temperature of from 600 to 1,000° C.
