摘要： A switching power source having a digital control system is provided. The switching power source includes a switching circuit 40 for switching an input power, an output circuit 50 for converting the switching output into a DC output, and a digital control 70. The digital control 70 is adapted to receive an output voltage analog signal AS1 and an output current analog signal AS2, and to convert the signals AS1 and AS2 into digital signals. It further functions to calculate, based on the digital signals, a command value for determining at least one of the switching frequency and the on or off time of the main switch 42. The operation of the main switch 42 is controlled in accordance with the command value. Information on power source input voltage or load terminal voltage is obtained through an assumption based on the signals AS1 and AS2.

摘要： Switching elements in an inverter main circuit are responsive to switching control signals. Phase voltages are applied to a polyphase load via the switching elements. Basic voltage command values are generated for phases of the polyphase load respectively. The basic voltage command values are converted into final voltage command values respectively. During a time interval for which at least two of the basic voltage command values are approximately equal to each other, the final voltage command values corresponding to the two of the basic voltage command values are equal to one of a maximum and a minimum. A carrier wave is subjected to pulse-width modulation responsive to the final voltage command values to produce the switching control signals. The produced switching control signals are outputted to the switching elements in the inverter main circuit.

摘要： To provide a mouth guard-preparing sheet from which a mouth guard to be used for preventing teeth and their surrounding tissues from a trauma occurred mainly in sports and having a uniform thickness between the right and left sides thereof can be prepared, without causing a problem in the thickness of an anterior teeth portion becoming thin in the preparation of a custom-made mouth guard by heat-sucking. The mouth guard-preparing sheet is made of a thermoplastic resin having a plane shape substantially coincident with a shape of a fixed frame of a heat-sucking type mouth preparation device and provided with a mouth guard portion from a site to be contacted with a labial surface side of a gingiva of an anterior teeth portion to a molar portion side and an elongation tab portion in an exterior direction of a mouth guard portion, wherein said mouth guard portion has a thickness of 1.5˜10 mm; said elongation tab portion has a thickness of 0.1˜0.95 times the thickness of said mouth guard portion; and a stepped portion between the mouth guard portion and the elongation tap portion is in a straight line.

摘要： To provide a root canal filling material remover that can remove a root canal filling material such as a gutta-percha point which is liable to remain in a root apex portion, or a sealer for root canal filling which is liable to enter into a dental pulp of a root canal wall and remain therein, after being removed during the re-treatment of a root canal, in a simple operation, without need of an excessive root canal enlargement operation as has been seen before, the root canal filling material remover contains at least one member selected from limonene, eucalyptus oil, chloroform and xylene, and a surfactant. Further, a polishing material may be added to the root canal filling remover.
