    摘要： An optical disc driving device includes a control circuit 4 for performing a gain adjustment for each of two recording surfaces of a multilayered optical disc 1 on the basis of an FE signal in such a way as to maintain a state in which light is focused onto either of the recording surfaces, to generate a focus servo loop signal, and for generating a focus jump signal for causing either a transition from a state in which the light is focused onto one recording surface to a state in which the light is focused onto the other recording surface, or a transition in the opposite direction from a threshold set up on the basis of an amount of gain adjustment, and a focus actuator driving circuit 5 for performing either a focus jump or an operation of maintaining the state in which the light is focused.

    摘要： A disc apparatus includes a readout unit, an audio signal output unit, a memory, a switch, and a controller. The readout unit reads out data from a disc wherein the data includes at least digital audio data. The audio signal output unit produces an audio signal output in accordance with the digital audio data. The memory stores the digital audio data read from the disc by the readout unit. The switch switches the digital audio data supplied to the audio signal output unit between the digital audio data stored in the memory and the digital audio data currently being read by the readout unit. Furthermore, the controller controls the readout unit and the memory so that, prior to a playback start operation, the digital audio data of a first predetermined period from a beginning of at least one program is read out by the readout unit and stored in the memory; controls the switch so that, at a beginning of the playback start operation, the audio signal output unit produces the audio signal output based on the digital audio data stored in the memory; and controls the switch so that, a second predetermined period after the start operation, the audio signal output unit produces the audio signal output based on the digital audio data currently being read out by the readout unit.

    摘要： When a light and porous inorganic substance is employed in a large amount as a excipient, it is impossible in the subsequent tabletting step using a tabletting machine to supply a desired amount of the resultant powder into a mortar having a definite diameter. As a result, extremely light tablets are produced. A method of producing the tablet is characterized by including dissolving or dispersing an oily substance, a liquid substance derived from a natural product or a low-melting substance in an organic solvent, allowing a porous calcium silicate powder to adsorb and hold the solution, adding a starch and/or a saccharide thereto, granulating the obtained mixture to give granules having an appropriate loose bulk density, and then compression molding those granules to give tablets.
