Abstract: The present invention is directed to provide a tape drive capable of securely pressing and holding a thin-type or a thick-type loaded tape cartridge being different in case thicknesses, so as to be vertically immovable. The tape drive D accommodates within it a loading frame 28 for receiving and supporting each tape cartridge 40A, 40B being different in case thicknesses and a holder 29 for holding the tape cartridge 40A, 40B by pressing the cartridge. The side wall 31 of the loading frame is provided with a pair of upper and lower sensors 34, 35 for identifying the thin-type and the thick-type loaded tape cartridges. The holder 29 is displaced to a height position matching with the loaded tape cartridge 40A, 40B based on the tape cartridge size detected by the sensors 34, 35.

Abstract: A tape cartridge capable of recording and reading out large and small tape cartridges with different widths is provided. The tape cartridge comprises a pair of right and left hubs for winding a tape which is winded off from one hub and is wound around the other hub via tape guides. A passage for light injection and a passage for light ejecting of the tape end detection light are opened respectively on a side wall of a case of a main body facing a tape traveling path between the tape guide and the hub, and an optical path inverted body facing a pair of passages across the tape traveling path is arranged in the case of the main body. One of the passages for light injection and the passages for light ejecting in the large and small tape cartridges is formed at a prescribed distance from the reference surface.

Abstract: A compatible type tape cartridge capable of recording and reading out large and small tape cartridges C1 and C2 with different widths in common with the same tape driver, which comprise a pair of right and left hubs 3 for winding a tape 2 which is winded off from one hub 3 and is winded around the other hub 3 via tape guides 4. A passage for light injection 15 and a passage for light ejecting 16 of the tape end detection light are opened respectively on a side wall 14 of a case of a main body 1 facing a tape traveling path between the tape guide 4 and the hub 3, and an optical path inverted body 17 facing a pair of passages 15 and 16 across the tape traveling path is arranged in the case of the main body 1.

Abstract: A single-reel tape cartridge includes a casing having a drive access hole defined therein, and a single tape reel rotatably accommodated within the casing and having a length of tape wound therearound. The tape reel includes a first flange having an opening defined therein, and a second flange with a hollow reel hub intervening therebetween. The tape cartridge includes a reel locking mechanism for preventing the tape reel from undergoing any arbitrary motion within the casing and a reel restraint mechanism for preventing the reel from undergoing an arbitrary motion in a direction laterally within the casing.

Abstract: A secondary battery has a positive electrode, an electrolyte, and a negative electrode. The electrolyte is made up of a high molecular gel electrolyte comprising a matrix polymer and an electrolyte solution included in the matrix polymer. The electrolyte solution is formed by dissolving an ionic compound in a nonaqueous organic solvent. The matrix polymer forms a high molecular network by dispersing (i) a compound containing at least two polymerizable functional groups, (ii) compound having a polymerizable functional group and containing one of a carbonyl group, an amido group, and an oxyalkylene group, and (iii) a vinylidene fluoride polymer and polymerizing them.

Abstract: A heat resistant derivative conductive polymer containing nitrogen atoms exclusively in units of polyaniline or a derivative thereof contains a sulfonic acid compound as a dopant, and the percentage of sulfonic acid groups per recurring unit of the polyaniline or derivative thereof is set to 28 to 40%. Also, a solid electrolytic capacitor uses a solid electrolyte of polyaniline or derivative thereof containing a sulfonic acid compound as a dopant, wherein the percentage of sulfonic acid groups per recurring unit of polyaniline or derivative thereof is set to 28 to 40%. In this selected range of the concentration of the dopant, the conductivity and the pyrolysis commencement temperature characteristics are excellent.

Abstract: A process for the preparation of polyaniline by an oxidation polymerization of aniline with use of an oxidizing agent and a protonic acid, wherein the pKa value of a byproduct produced by the reduction of the oxidizing agent is greater than the pKa value of the protonic acid. The protonic acid is an aromatic sulfonic acid compound having at least a sulfonic-acid group. A process is also provided for the formation of a solid electrolytic capacitor including an electrolyte of the polyaniline. A method is provided of improving the electrical conductivity of the polyaniline prepared by the above process. The polyaniline is subjected to a heat treatment in a vacuum or an inert gas in which a partial pressure of oxygen is 10 mmHg or below.

Abstract: In a solid electrolyte capacitor in which the solid electrolyte is polyaniline or a polymer of an aniline derivative doped with a prototnic acid, a disulfonic acid represented by the general formula (1) is used as the protonic acid to enhance high-temperature endurance and humidity resistance of the solid electrolyte: ##STR1## where R is m-phenylene, p-phenylene or a C.sub.7 to C.sub.10 bridged cycloalkylene group, and n and m are independently integers from 1 to 3. Disulfonic acids of the general formula (1) are novel compounds.

Abstract: A light-resistant polyaniline light-shielding film, comprising a thin polyaniline film in which Lewis acid is contained in an amount of 0.1 to 5 mol % per monomer unit of the polyaniline.
