Abstract: Provided is an electronic pen that includes a body portion housing of an electronic pen body portion has housed therein a refill body and a circuit board having a side switch formed by a push button switch mounted thereon, and has a pen-point opening portion through which a pen point of the refill body protrudes. A pressing member is provided in a side opening portion of the body portion housing such that the pressing member is disposed on the side switch in such a manner as to be prevented by an engagement portion from protruding outwardly from a side surface of the body portion housing. The side switch of the circuit board is operated through the pressing member of the electronic pen body portion when an operation unit of the outer housing having the electronic pen body portion installed therein is pressed.

Abstract: A plant performance management method includes a step of evaluating performance of a plant based on a relationship between at least two items of data from operating data and a step of analyzing a cause that makes the performance of the plant abnormal based on the operating data in a case in which the performance of the plant is evaluated as abnormal.

Abstract: A generating unit of an information sharing system generates, in a case where one of a plurality of users enters a comment, notice information for notifying the other users of a notification of the comment. When the user who enters the comment specifies a destination of the comment, a destination associating unit associates destination identifying information for identifying the specified destination with the notice information. A display information generating unit generates display information for displaying, on a display unit of the user, a screen on which the notification of the comment that specifies the user as the destination is distinguished from the notification of the comment that does not specify the user as the destination, based on the notice information and the destination identifying information.

Abstract: An audio data receiving apparatus includes a receiving unit configured to receive audio data sampled in accordance with a first clock signal; a synchronization unit configured to generate a second clock signal that is synchronized with the first clock signal by extracting clock components contained in the audio data; a demodulator configured to demodulate the audio data in accordance with the second clock signal; an oversampling unit configured to oversample the audio data demodulated by the demodulator by using a frequency higher than a frequency of the second clock signal; a clock generator configured to generate a third clock signal having a frequency nearly equal to the first clock signal; and a data output unit configured to output the audio data oversampled by the oversampling unit in accordance with the third clock signal generated by the clock generator.

Abstract: A transmission device includes: a communication unit performing communication with one or more receiving devices; a distance measurement unit measuring direct distances to the receiving devices; a transmission data setting unit setting transmission data including content data including audio and time information indicating the time when reproduction of content data is started for the receiving devices whose distances are measured based on the measured distances; and a transmission processing unit transmitting transmission data set by the transmission data setting unit to corresponding receiving devices of transmission targets all at once. The transmission data setting unit sets time when the device itself starts reproduction of the content data as a reference time, and sets the time information for synchronizing audio indicated by the content data reproduced in the device itself with audio indicated by the content data reproduced in the receiving devices for each receiving device using the set reference time.
