摘要:
An electronic cash register employing a price-look-up table includes a detachable recording medium for recording item codes and the corresponding item prices, and a reader for reading the data from the detachable recording medium. During a transaction operation, the recording medium is checked to determine whether it is connected to the reader, and, if it is, the detachable recording medium is searched for an item involved in the transaction operation. If that item is present on the detachable recording medium a transaction operation based on the medium-recorded prices for that item, rather than a previously stored price for that item, is carried out.
摘要:
A magnetic recording medium, comprising an aromatic polyimide film and a magnetic layer of a ferromagnetic material provided on the aromatic polyimide film. The aromatic polyimide film is prepared by imidation of a film formed from a solution of a polyamic acid solution obtained by copolymerization of an aromatic amine component comprising at least 30 mole % of p-phenylene diamine and 0 to 70 mole % of diaminodiphenylether, respectively based on the total amount of the aromatic amine component, and a tetracarboxylic acid dianhydride.

A hermetically sealed motor compressor for use in a small-size refrigerating machine, refrigerator, freezer and the like has a compressor on which is mounted a silencer comprising in combination a suction muffler of thermal insulating and a discharge muffler made of formed metal plates. The suction muffler has an suction port disposed near the open end of a suction coupling fixed to a sealed casing, and also has an connection pipe connected to a compressor cylinder and having a distal end fitted directly in a hole defined in an head plate which is mounted on the head of the cylinder. A refrigerant gas as it is introduced from the suction coupling into the sealed casing can be drawn into the cylinder through the suction port, the suction muffler and the connection pipe to minimize heat transfer to the suction gas, so that the compressor can increase its volumetric efficiency.

A magnetoresistive effect thin film magnetic sensor has a temperature compensating magnetoresistive effect (MR) element arranged non-parallel to a signal detecting MR element to prevent the temperature compensating MR element from being influenced by an external magnetic signal field. Alternatively, it has an L-shaped temperature compensating MR element arranged closely to the signal detecting MR element to prevent the temperature compensating MR element from being influenced by the external magnetic signal field. It further has a magnet member arranged closely to or in contact with the temperature compensating MR element to enhance a positional precision of the temperature compensation and reduce a time lag.
摘要:
The present invention is directed to improvements in a perpendicular magnetic recording-reproducing head. One of the improvements comprises the use of a magneto-resistive effect element to form the main pole of the magnetic head. This feature of the invention enables a stable and faithful reproduction of information recorded in a magnetic recording medium up to the shortest wavelength and to obtain a sufficiently large reproducing output signal. Another improvement comprises the use of such magneto-resistive effect elements in layers. The multilayer structure permits production of a large reproducing output and also an optimum S/N ratio even if the width of track is small.

It is an object of the present invention to provide a material composition for a bulk-heterojunction-type organic photoelectric conversion layer having high photoelectric conversion efficiency and durability through formation of a stable phase-separated structure by drying in a short time with high productivity and to provide an organic photoelectric conversion element, a method of producing the organic photoelectric conversion element, and a solar cell. The material composition for an organic photoelectric conversion layer contains at least a p-type conjugated polymer semiconductor material being a copolymer having a main chain including an electron-donating group and an electron-withdrawing group, an n-type organic semiconductor material having electron acceptability, and a solvent. The solvent is represented by a general formula (1).

Provided are a resinous reflecting optical element that achieves high mirror surface precision by mitigating the warping effects associated with contraction during resin hardening and suppressing the distortion of a mirror surface that results from resistance to mold release, and a scanning optical device that uses said reflecting optical element. The reflecting optical element is characterized by having a long, tabular substrate (3), a mirror surface section (2) positioned on one surface of the substrate (3), and a hollow portion (4) positioned within the interior of the substrate (3), and is also characterized in that, as a result of configuring so that the hollow portion (4) is longer than the mirror surface section (2), warping and sink marks which form due to contraction during resin hardening are mitigated across the entire mirror surface section (2), and in that the entire mirror surface section (2) protrudes above the surface of the substrate (3), thereby suppressing the increase in resistance to mold release that occurs when a metallic mold is gripped by the molding during resin contraction, and preventing distortion of the mirror surface section (2) that is caused by resistance to mold release.
