Abstract: A vehicular electric power source controller that controls the electrification of an electrical load mounted in a vehicle includes: a first electrical load that are a portion of the electrical load mounted in the vehicle; a second electrical load that are electrified preferentially over first electrical loads when a vehicle is parked; an electric power source-switching ECU, an ACC relay and an IG relay that switch not only the electrification of the first electrical load to but also the electrification of the second electrical load; and an electric power source management ECU, a parked state ACC relay and a parked state IG relay that switch the electrification of only the second electrical load. The vehicular electric power source controller curbs wasteful electricity consumption while operating an electrical load that is used while the vehicle is parked.

Abstract: An optical disk and method of recording information on the same are provided in which music and images such as, motion pictures can be recorded without dropout of information by more reducing the time necessary to replace than in the prior art. On this optical disk are provided a plurality of management areas, of which one or a plurality of the management areas are located between the innermost and outermost peripheries and are used for storing replacement information. Therefore, the optical head need not be moved to the innermost or outermost periphery at the time of replacement unlike the prior art.

Abstract: In a character pattern utilization system provided with a plurality of character patterns differing in size or style from one another for each of a plurality of characters which are associated with corresponding character codes, the character patterns of each type are compression-coded beforehand using one of a plurality of code tables which corresponds to the character types. Upon designation of a code and a pattern type for a character to be outputted, the compression-coded character pattern corresponding to it is restored using the code table corresponding to said pattern type and is outputted.

Abstract: This invention relates to an induction heating apparatus including a digitized control circuit and digitizing the ON/OFF control circuit for a switching element which has hitherto utilized the R-C time constant, thereby eliminating the defects, such as a change in the R-C time constant with the time ageing and non-stabilization of the heating output accompanied by a temperature change. Since the digitized control circuit can be a monolithic integrated circuit, the apparatus as a whole can be miniaturized or smaller in thickness and inexpensive to produce. Furthermore, the induction heating apparatus realizes by the digitized control circuit quick overcurrent protection, exact detection of unsuitable load, prevention of noise generation, and facility of design corresponding to various power supply voltage.

Abstract: An electromagnetic induction heating apparatus having a detecting circuit for detecting an unsuitable load thereof, which detects an input AC power and an exciting current for an inverter so that the levels thereof are compared with each other to discriminate whether or not the load is suitable and it is possible to discriminate the load with accuracy regardless of the height of set level for the input power and current intensity of the detected exciting current, is biased, thereby raising the unsuitable load detection accuracy when oscillation starts.
