Abstract: In an image forming apparatus, a length of a patch pattern from a first patch to a last patch included in the patch pattern is longer than a circumferential length that is a length of an intermediate transfer belt in a conveyance direction, an engine control unit forms patches included in a range within the circumferential length in a first density (low density), forms patches included in ranges beyond the circumferential length in a second density (high density) darker than the first density, from among the patches included in the patch pattern, and executes image adjustment control.

Abstract: A bracket for a speaker is capable of ensuring strength when the speaker is attached by using an attachment plate, and enhances workability in folding of the attachment plate when the speaker is attached without using the attachment plate. The bracket includes a frame-shaped support portion which supports a speaker, and a mounting member which is used for attaching the speaker supported by the support portion to the outside and is provided in the support portion. A plurality of grooves having different extension directions are continuously formed on a base part of the mounting member, the base part connecting the mounting member and the support portion.

Abstract: Provided is a bracket for a speaker, the bracket being capable of ensuring the strength when the speaker is attached by using an attachment plate, and also enhancing the workability in folding of the attachment plate when the speaker is attached without using the attachment plate. The present invention includes: a frame-shaped support portion 10 which supports a speaker; and a mounting member 20 which is used for attaching the speaker supported by the support portion 10 to the outside and is provided in the support portion 10, wherein a plurality of grooves having different extension directions are continuously formed on a base part of the mounting member 20, the base part connecting the mounting member 20 and the support portion 10.

Abstract: A toothbrush capable of permitting tips of fillings thereof to enter or reach areas such as recesses between teeth, boundaries between teeth and gingivae, and the like to effectively remove dental plaque and the like and exhibit a soft feeling sufficient to prevent damage to gingivae. The toothbrush includes fillings made of a synthetic filament material. The fillings are each formed at both tips thereof into a pointed tapered shape and tied up into a plurality of bundles. The pointed tapered tips of the fillings are each formed with a length of 4 to 8 mm and a non-tapered section of each of the fillings is formed with a maximum diameter of 0.16 to 0.20 mm. Filling setting holes of a filling setting base provided at distal end of a handle of the toothbrush so as to set the bundles of the fillings thereon are formed with a diameter of 1.5 to 2.0 mm and spaced from other holes at an interval of 1.0 to 1.2 mm in the longitudinal direction of the handle.

Abstract: The invention relates to a brush which comprises a handle portion, a base portion formed with recesses for holding filaments or bristles, an insert which acts as holding means for holding the filaments or bristles in the recesses, and filaments or bristles held in the recesses by the insert. According to the invention, the base portion of the brush, and possible also the handle portion, is formed of a particular plastic which permits the insert which holds the filaments or bristles to press into the sides of the recesses with considerable pressure without cracking the sides so as to permit better holding of the filaments or bristles in the brush base.
