摘要:
A memory medium for information storage and reproduction and an apparatus for reading information from the memory medium are set forth herein. The memory medium includes a solid storage layer formed of a pyroelectric and electro-optic material, and information is stored in the medium through local residual polarization of the layer owing to the pyroelectrical property of the material. The apparatus includes: (a) a light source for emitting a laser beam toward the medium; (b) a power source for applying electric power to the light source; (c) an optical system for converging the beam on the layer, so as to form a beam spot with a suitable size; (d) a sensing device for detecting an intensity of a laser beam reflected by, or a laser beam transmitted through, the layer, the intensity being changed owing to variation in refractive index of the layer due to the local residual polarization, the changes in the refractive index being based on the electro-optical property of the material, the sensing device generating a detection signal indicative of an intensity of the detected beam; and (e) a control device responsive to the sensing device, for generating a reproduction signal corresponding to the detection signal, the reproduction signal being used for the information reproduction.

An on-screen signal processing apparatus comprises a first display memory for storing binary image data, a second display memory for storing decoration data (i.e., “attribute data”) for decorating the binary image data stored in the first display memory in a unit of a fixed plurality of pixels, and a first color look-up table for storing data concerning a character color and a background color for decorating the binary image data stored in the first display memory. A first converter reads the binary image data of the first display memory and the decoration data of the second display memory every unit of the fixed plurality of pixels and searches the first color look-up table based on the character color and the background color designated in the decoration data, and further performs color-conversion to the binary image data of the first display memory.

A control apparatus for a gas sensor with a built-in heater is provided which can prevent damage to, deterioration of, and reduction in accuracy of detection of, a gas sensor. When an ignition switch is turned ON, supply of electricity to a heater 27 starts, and when the temperature in the vicinity of a gas sensor 15 (gas temperature of gas detection chamber 24) Ts becomes greater than a predetermined temperature #Ti at start, or when a predetermined electricity supply time after start of supply of electricity to the heater 27 has elapsed, the gas sensor 15 is started. The flow of off-gas is started simultaneously with starting of the gas sensor 15, or after starting. When the ignition switch is turned OFF, the flow of off gas is stopped, and the supply of electric power to the gas sensor 15 is stopped. In a state where a temperature difference ΔT between the gas temperature Ts inside the gas detection chamber 24, and an upstream gas temperature Tg is maintained within a predetermined range, the supply of electricity to the heater 27 is stopped after a predetermined time has elapsed after operation of the gas sensor 15 is stopped.
