Abstract: An information processing apparatus includes a memory, a connection port to connect to an external recording medium including a first recording medium and a second recording medium, and circuitry. The circuitry is to store, in the memory, data and license information of the data read from the first recording medium connected to the connection port, invalidate the license information stored in the first recording medium, store the data and the license information read from the memory in the second recording medium that is connected to the connection port after the first recording medium has been disconnected from the connection port, and invalidate the license information stored in the memory.

Abstract: Vehicular theft preventing device includes: an operation switch for switching between different displays on a display section, the operation switch being constructed to function also as a setting switch operable to set the preventing device in an alert mode; a main switch for turning on/off a power supply; and a control section for controlling the display section and an alarm unit, the controlling section setting the preventing device in the alert mode upon fulfillment of a condition that the operation switch has been operated while the main switch is in an OFF state.

Abstract: In order to keep down soot production and to enable every part of the workpiece, including deep concavities to be uniformly carburized by vacuum carburizing, and to enable decreases in the quantities of gas and heat employed, carburizing treatment is performed in the heating chamber 2 of a vacuum carburizing furnace 1 with workpieces M being heated while acetylene gas is supplied from a carburizing gas source C inside the heating chamber 2, and the inside of the heating chamber 2 being evacuated by a vacuum evacuation source V to give a vacuum of .ltoreq.1 kPa.

Abstract: Herein disclosed are a vacuum-degreasing cleaning method for degreasing a work by cleaning it with a solvent vapor under reduced pressure, and a vacuum-cleaning machine for practicing the method. This method comprises the vapor-cleaning step of cleaning the work under reduced pressure with a vapor of a petroleum solvent, and the drying step of drying the surface of the work under reduced pressure. This cleaning method can clean the work while preventing the deterioration of the working atmosphere and the air pollution and can reduce the initial cost and the running cost for the work cleaning operation. Moreover, the cleaning efficiency can be safely enhanced with neither any thermal influence upon nor any rust upon the work.
