Abstract: A battery frame is fixed to a chassis and a battery pack is assembled to the battery frame. The battery frame includes a pair of crossbars and a pair of side bars. The crossbars extend in the vehicle width direction while being spaced apart in the vehicle front-rear direction, and have both ends in the vehicle width direction fixed to the side members. The side bars extend in the vehicle front-rear direction while being spaced apart in the vehicle width direction, and have front ends and rear ends detachably fixed to the crossbars.

Abstract: A solder product 20 includes: a lead-free solder part 21 containing 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 product 20 to form a surface layer 22. The carboxylic acid is preferably a fatty acid having 12 to 16 carbons, and more preferably a palmitic acid.

Abstract: 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.

Abstract: In a portable information terminal, a display screen is equipped at one surface side of an upper half portion. Plural keys for inputting characters are provided at a surface of a lower half portion which is overlapped with the upper half portion, and an operating unit for performing the control operation of the display content of the display screen is provided at a portion of the lower half portion which is exposed to the outside even when the upper and lower half portions are overlapped with each other. Further, a controller for performing the display control of 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 so that one end sides thereof are mutually separated from each other from the overlap state, and also they are joined to each other so as to be rotatable around a second rotational axis perpendicular to the first rotational axis.

Abstract: 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.

Abstract: 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.

Abstract: 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.
