Abstract: A packing member, a toner container, and a packing method. The packing member contains the toner container, and the packing member includes a box containing the toner container with a gap between one side of the box and a container body and between the one side of the box and a large-dimension portion of the toner container, a first pressing portion that presses the container body, and a second pressing portion that presses the large-dimension portion. In the packing member, the large-dimension portion of the toner container is disposed at one end of the container body, and the large-dimension portion has a wider dimension than the container body in a direction orthogonal to a longitudinal direction of the toner container. In the packing member, the container body contacts, with first contact force, a first bearer inside the box to maintain the gap.

Abstract: An information processing device includes: a signal acquisition unit that acquires an audio signal; a storage unit that stores head-related transfer function information corresponding to a user; a determination processing unit that determines whether or not the head-related transfer function information corresponding to the user is stored in another information processing device; a transfer function acquisition unit that acquires the head-related transfer function information corresponding to the user; and a function application unit that applies the head-related transfer function information corresponding to the user to the audio signal.

Abstract: To enable channel setting to be performed easily and accurately to speakers. Thus, provided is a speaker system including: N number of speakers, the N being three or more; and a signal processing device capable of communicating with each speaker. The signal processing device performs processing of recognizing two arrangement reference speakers with reception of notification that a designation operation has been received from a user, from two speakers among the N number of speakers, and processing of acquiring distance information between each speaker. The signal processing device recognizes a relative-position relationship between the N number of speakers, with the two arrangement reference speakers and the distance information between each speaker. Then, the signal processing device automatically sets a channel to each speaker, on the basis of the relative-position relationship recognized.

Abstract: A recording/reproducing apparatus includes: a light source; a first correction section to correct a position of an objective lens that collects laser light from the light source on a surface of an optical disc based on a focus bias setting value obtained from a focus bias value; a second correction section to correct an aberration of the laser light based on an aberration correction setting value obtained from an aberration correction value; an evaluation value generation section to generate an evaluation value; a focus bias adjustment section to change plus/minus of the focus bias value and calculate a new focus bias value based on the evaluation value every time a first cycle passes; and an aberration adjustment section to change plus/minus of the aberration correction value and calculate a new aberration correction value every time a second cycle passes, in parallel with an update of the focus bias value.

Abstract: A recording/playback apparatus includes an optical head unit, a laser drive pulse generator, a power setting unit, an evaluation value calculator, and an adjustment controller. The adjustment controller performs control such that recording operations for adjusting laser drive pulses are performed on an optical recording medium by changing the adjustment setting for the laser drive pulses to different adjustment setting conditions under a condition that each of two or more levels of power of the laser light is set to obtain a quality evaluation value for each adjustment setting condition, and determines the adjustment setting for the laser drive pulses on the basis of the obtained quality evaluation value, and sets the determined adjustment setting in the laser drive pulse generator.

Abstract: An optical recording and reproducing apparatus includes a recording-pulse-shift setting unit that shifts a front edge and a rear edge of a recording pulse and sets a write strategy of the recording pulse, an mark-edge-position evaluating unit that detects a front edge and a rear edge of a mark formed and detects a front mark edge position error and a rear mark edge position error, an assuming unit that assumes that the front mark edge position error is represented by a first linear function and assumes that the rear mark edge position error is represented by a second linear function, a sensitivity calculating unit that executes test recording and calculates sensitivities, and a write-strategy calculating unit that calculates a write strategy of the recording pulse on the basis of the sensitivities.
