Abstract: Laser processing device (100) includes laser oscillator (10) that generates laser light beam (LB), optical fiber (30) that transmits laser light beam (LB), laser head (40) that emits laser light beam (LB) to workpiece (W), and chiller (50) that passes and circulates cooling water through laser oscillator (10) to cool laser oscillator (10). Laser oscillator (10) includes: a plurality of laser diodes; and a base having a cooling water channel therein and having the laser diodes mounted on a surface thereof. Laser processing device (100) is configured to change the incident angle of laser light beam (LB) entering optical fiber (30) by changing the water pressure of the cooling water flowing through the cooling water channel.

Abstract: A laser light emission head includes a laser light shaping unit laser light shaping unit having a first housing configured such that laser light enters an upper portion of the first housing and optical components configured to shape the laser light into a desired shape are arranged in the first housing and a glass holder to which multiple protection glasses are attached with a predetermined spacing. Moreover, the laser light emission head includes a cleaning unit having a second housing in which a cleaning mechanism for cleaning the protection glasses attached to the glass holder is arranged. The glass holder is configured movably between the first housing and the second housing.

Abstract: An electronic musical apparatus which makes it possible to execute functions provided in advance in the electronic musical apparatus. Contents data including link information indicative of a link to a file in which at least one command for executing at least one predetermined function provided in the electronic musical apparatus is written is acquired. A predetermined screen is displayed based on the acquired contents data. The file linked by the link information is acquired when a user performs a predetermined operation on the link information presented on the displayed predetermined screen. At least one command written in the acquired file is interpreted, and the electronic musical apparatus is controlled to execute at least one predetermined function indicated by the interpreted command.

Abstract: A browser portion BR obtains a reproduction manner specifying file from a content distribution server 30, and delivers the same to a reproduction control portion CT. The reproduction control portion CT obtains from the content distribution server 30 a music content file designated by a reproduction content list in the reproduction manner specifying file. The reproduction control portion CT reproduces, in cooperation with a tone generating circuit 43, a music piece corresponding to the music content in a reproduction manner specified by the reproduction manner specifying file. The reproduction control portion CT displays the music content on a display device 42 in a display manner specified by a reproduction manner specifying file. When a user operates an input operation element group 41 for changing the display manner of the display device 42, the reproduction control portion CT changes the display manner of the display device 42.

Abstract: An acoustic diaphragm comprising two or more laminated composite sheets, being formed into a shape with a curved surface. The composite sheet is made up of sliced wood and nonwoven fabric cloth consisting of adhesive resin, being stuck on backside of the sliced wood. Thus, it is capable of forming a three-dimensional shape, making use of natural wood characteristics, and improving unevenness of natural material properties. In one preferred embodiment, the diaphragm is woven of slit wood or other article forming the weft and synthetic or inorganic fibers forming the warp.
