A solder productincludes: a lead-free solder partcontaining tin as a main component and a metal element other than lead as a secondary component; and a carboxylic acid having 10 to 20 carbons, the carboxylic acid being mainly distributed over the surface of the solder productto form a surface layer. The carboxylic acid is preferably a fatty acid having 12 to 16 carbons, and more preferably a palmitic acid.

In a portable information terminal, a display screen is provided on one surface of an upper half portion, and keys for inputting characters are provided at a surface of a lower half portion. The upper half portion can be pivoted to overlay the lower half portion. An operating unit for performing the control operation of the display content of the screen is provided at a portion of the lower half portion that is exposed even when the upper half portion overlays the lower half portion. A controller for controlling the display screen and other control processing is equipped in the lower half portion. The upper half portion and the lower half portion are rotatably joined to each other around a first rotational axis so as to be opened from the overlap state. The upper and lower half portions are also joined to each other so as to be rotatable around a second rotational axis perpendicular to the first rotational axis. A detector determines whether the display screen of the upper half portion faces the key-arranged surface of the lower half portion or whether the back side of the upper half portion faces the key-arranged surface side. In accordance with the detection result, the controller rotates the display image on the display screen by 180 degrees.

Portable information terminal

A jack is provided to be inserted with a cable dedicated to analog transmission, a cable dedicated to digital transmission, and a cable dedicated to analog and digital transmissions. A recording device is also provided to have the jack and a cable identifying unit so that the signal to be recorded is automatically switched according to the transmitted digital signal and the cable identified result given by the cable identifying unit.

Transmission cable, jack to which transmission cable is inserted, and recorded

An optical visualizing apparatus for use in a head mounted display unit contains a liquid crystal shutter designed to allow a viewer to see both an image display and scenery outside of the image display at the same time. The apparatus contains a screen placed in front of the viewer's eyes, an optical visualizing unit to display an image on the screen, a mounting unit for supporting the optical visualizing unit in front of the viewer's face, and a control unit that can either suspend transmission of the image and allow clear sighting through the screen without the image or, if desired, simultaneous display of the image and sighting of scenery outside of the image. The control unit preferably controls a liquid crystal shutter that can adjust the amount of external light entering the display apparatus over two ranges, one range corresponding to the image area and the other range corresponding to the area surrounding the image area, so that the user can view a displayed image and external scenery clearly and simultaneously.

Head-mounted image display having selective image suspension control and

In a reproducing device, e.g., in the portable tape player, the sound leakage from earphones is effectively avoided by directly detecting the signal level of medium to high frequency sounds at the earphone, and suppressing the signal level depending on the detected result thereof, so that the deterioration in sound quality is prevented and the sound leakage is effectively reduced.
