Abstract:
An optical recording medium having on a substrate an optical recording film and an inorganic dielectric film containing a target element of a metal or metalloid, such as Si or Ge, is produced by forming the inorganic dielectric film by subjecting a sputtering target comprising a crystal of the target element to DC sputtering in a reactive gas atmosphere. Abnormal discharge leading to inferior products and a lower productivity is suppressed by constituting the sputtering target to have a sputtering surface conforming to a lattice plane of the crystal free from a void allowing intrusion of an atom, ion or radical originating from the reactive gas into the unit lattice. In case of an Si single crystal having a diamond structure, the sputtering surface is preferably conformed to a lattice plane represented by Miller indices (1,0,0) or (1,1,1). The sputtering target is preferably provided with a chamfer adjacent to the sputtering surface.

The design model managing part includes a model area creating unit for securing a model area and formatting the model area into function figures, layers, figure groups, and figures, a model accessing unit for accessing the model area and an external file, a model data retrieving unit for hierarchically retrieving data from the model area and a model updating unit for creating model information and correcting figure information.
Abstract:
Transaction data representing a transaction to be processed is input through an input terminal. An interface unit assigns the input transaction data a business code identifying the business activities of a company involved in the transaction represented by the transaction data, and a type code identifying an account title classified based on a cost element. A journalizing unit refers to a master information storage unit, and journalizes the transaction data based on the business code and the type code. The journal result is stored in a database accessible from the terminal device of the accounting division.
Abstract:
An electroless copper plating solution using glyoxylic acid as a reducing agent, which is small in the reacting quantity of Cannizzaro reaction, does not largely cause precipitation of the salt accumulated in the electroless copper plating solution by the plating reaction and Cannizzaro reaction, and can be used stably over a long period of time. The electroless copper plating solution comprises copper ion, a complexing agent for copper ion, a reducing agent for copper ion and a pH adjusting agent, wherein the reducing agent for copper ion is glyoxylic acid or a salt thereof, the pH adjusting agent is potassium hydroxide and the electroless copper plating solution contains at least one member selected from metasilicic acid, metasilicic acid salt, germanium dioxide, germanic acid salt, phosphoric acid, phosphoric acid salt, vanadic acid, vanadic acid salt, stannic acid and stannic acid salt in an amount of 0.0001 mol/L or more.

Abstract:
A magnetooptical recording medium has a first magnetic layer which is an in-plane magnetization film at both room temperature and high temperatures and changed to a perpendicular magnetization film at intermediate temperatures, and a second magnetic layer which is composed of a perpendicular magnetization film. The recording medium enables realization of high S/N reproduction of information recorded at a pitch below the diffraction limit of light with a simple structure, and further improvement in linear recording density and track density.
Abstract:
A magnetic thin film element is provided with a magnetoresistive film including a first magnetic layer composed of a perpendicular magnetization film, a second magnetic layer composed of a perpendicular magnetization film having a higher coercive force than that of the first magnetic layer, and a nonmagenetic layer interposed between the first magnetic layer and the second magnetic layer. The resistance of the magnetoresistive film varies depending on whether or not the magnetic spins of the first magnetic layer and the second magnetic layer are in the same direction.
Abstract:
Disclosed is a guide lug composition for a rubber track comprising 5 to 40 parts by weight of a fatty acid amide based on 100 parts by weight of a raw rubber material; or comprising 5 to 40 parts by weight of a Ultra High Molecular Weight Polyethylene (UHMW-PE) powder based on 100 parts by weight of a raw rubber material; or comprising 5 to 40 parts by weight of a fatty acid amide and 5 to 40 parts by weight of a UHMW-PE power based on 100 parts by weight of a raw rubber material. The guide lug composition serves to reduce abrasion of or damages to a guide lug, to improve the characteristics in preventing the rubber track from slipping off a wheel, which is called “detracking”, to reduce friction loss when the guide lug contacts and collides with the wheel thereby reducing energy losses.
