Abstract: A tapered roller bearing according to the present invention, in which the rolling surface of a tapered roller and raceway surfaces of internal and outer rings undergoes crowning. The total crowning amount of that crowning and the crowning amount of each raceway surface and rolling surface are set to preferred values. This allows reduction of the rolling friction of the internal and outer rings and the tapered roller, and the rotation torque of the tapered roller bearing according to the present invention.

Abstract: A picture to be reproduced and displayed on a television monitor (10) is discerned as a plurality of partitioned areas in correspondence to keys labeled “1” to “9” disposed on a remote control unit (R). After having zoomed in a picture in a partitioned center area by operating a zoom key disposed on the remote control unit, a partial picture in a partitioned area corresponding to a given one of the keys “1” to “9” is zoomed in with a desired magnification factor in response to operation of the given key. Position of the zoomed-in partial picture on a full screen and the magnification factor thereof can be visually recognized by displaying cursors correspondingly.

Abstract: A tapered roller bearing is designed to have a roller loading ratio in the range of 0.7 to 0.92 and a ratio of roller length to roller diameter in the range of 1.1 to 1.7 whereby oil agitation loss and rolling viscous resistance are reduced for achieving the reduction of running torque. Crownings are provided which are designed to have an outer-ring crowning parameter (=RCO/LRO) in the range of 30 to 150 and an inner-ring crowning parameter (=RCI/LRI) in the range of 50 to 260, provided that RCO denotes the radius of an outer ring crowning, LRO denotes the raceway length of an outer ring, RCI denotes the radius of an inner ring crowning and LRI denotes the raceway length of an inner ring. Thus, the rolling viscous resistance is reduced for achieving the reduction of running torque.

Abstract: A carbon material for electric double layer capacitor electrodes which is obtained by a heat treatment and an activation treatment of a material pitch having a softening point in a range of 150 to 350° C., a ratio of amounts by atom of hydrogen to carbon (H/C) in a range of 0.50 to 0.90 and a content of optically anisotropic components of 50% or greater. The material pitch is preferably a synthetic pitch obtained by polymerizing a condensed polycyclic hydrocarbon such as naphthalene, methylnaphthalene, anthracene, phenanthrene, acenaphthene, acenaphthylene and pyrene in the presence of an ultra-strong acid catalyst such as a hydrogen fluoride-boron trifluoride complex. Electric double layer capacitors having a high electrode density and a high electrostatic capacity per unit volume can be constructed using the carbon material.

The catalyst is produced from alloy fine particles obtained by first grinding an Al alloy containing quasi-crystals consisting of aluminum, copper and at least one metal atom selected from Fe, Ru and Os, and then leaching the ground Al alloy.

Abstract: A carbon heating element of excellent durability and thermal shock resistance, usable even in a special environment, for example, even in a strong oxidizing chemical, and having a sufficient capability of generating heat with smaller power consumption. The carbon heating element is formed by covering a carbon material, such as carbon fiber or a carbon fiber cloth with quarts glass, making the interior of the quartz glass vacuous or setting the pressure of the interior of the quartz to not higher than 0.2 atm. with substituted inert gas, and melt-scal the quartz glass.

Abstract: A novel information reproducing apparatus and information recording/reproducing apparatus capable of searching and selecting information with ease through common manipulations independent of recording media. A recording medium is employed from which start positions of recorded picture programs and start positions of scenes composing each picture program can be read out as data. Symbols corresponding to the picture programs recorded on the recording medium are displayed in an array on a single display screen. A given one of the symbols being displayed is selected, and reduced start pictures of plural scenes, respectively, which compose a picture program affixed with the selected given symbol are displayed in a partitioned array on the single display screen. A desired one of the plural start pictures of reduced size which are being displayed is selected and determined for reproducing the scene corresponding to the determined start picture fully over the single display screen.
