A thermosettable acrylic resin composition for powder coating comprising a mixture consisting essentially of (A) 100 parts by weight of an acrylic resin having a glass transition temperature of 10.degree. to 75.degree. C. and containing (a) 2 to 28 % by weight of a monomeric component containing epoxy group and (b) 0.1 to 8 % by weight of a monomeric component containing carboxyl or acid anhydride group, the gram equivalent ratio of said carboxyl groups to said epoxy groups contained in said acrylic resin being in the range from 1/2 to 1/20 (provided that the gram equivalent of an acid anhydride group is assumed to be equivalent to 2 gram equivalents of the carboxyl group) and (B) 0.5 to 25 parts by weight of a curing agent capable of crosslinking said acrylic resin (A). On being baked at 150.degree. to 220.degree. C. for 10 to 50 minutes, this composition gives a coating film excellent in strength, adherence, and surface leveling.

A leg device for height-adjustably supporting a supported object includes a leg shaft having a male thread portion, and an ascending/descending body supported on the leg shaft to be capable of ascending and descending. The ascending/descending body includes a base having a fixing part to be fixed to the supported object, a through hole for receiving the leg shaft therein, and an elastic piece, a lock body, and a release body. The lock body has an upper part pivotally assembled onto the base, and a female screw part engageable with the male thread portion. The lock body is pushed by the elastic piece toward the leg shaft inserted into the through hole. The release body has an operating part projecting outward from the base, and a striking part positioned inside the base. The release body can be operated to release the lock body.

A transmit-side STA transmits a wireless packet using a wireless channel which has been determined to be idle by both a physical carrier sense for determining based on received power whether the wireless channel is busy or idle and a virtual carrier sense for determining the wireless channel to be busy during set transmission inhibition time. At this time, the transmit-side STA sets transmission time used for the virtual carrier sense to a paired wireless channel which is affected by leakage from a transmitting wireless channel. This allows for setting transmission inhibition time to a paired wireless channel even when the paired wireless channel cannot successfully receive due to the effect caused by leakage from the transmitting wireless channel.

An electrical cable holder has a holder body having a fixing device (for example, anchor part) and a fastening part positioned beneath the fixing device (for example, anchor part) for provisionally placing an electrical cable (for example, power transmission cable); and a movable arm movably supported on the holder body for fastening the electrical cable (for example, power transmission cable) provisionally placed in the fastening part, between the movable arm and the fastening part. A lock device for locking the movable arm in a fastening state, in which the electrical cable (for example, power transmission cable) is fastened by the fastening part, is provided between the movable arm and the fastening part. A stationary device for maintaining a non-fastening state is provided between the holder body and the movable arm.

A holding device has an elastic locking piece having an extending part extending to the outside from a locking claw part. The contact part of an unlocking operating piece contacts the outside of the extending part to reduce the unlocking force of the unlocking operating piece. A sawtooth-form part is in a locked state when a locking piece of an elastic locking piece enters the sawtooth-form part. The elastic locking piece has the extending part extending outside from the locking claw part. The unlocking operating piece has a contact part for contacting with the extending part. The contact part contacts the outside of the extending part when the unlocking operating piece is pressed, the locking claw part of the elastic locking piece is ejected from the indented part of the sawtooth-form part by the contact, and the locked state between the sawtooth-form part and the locking claw part is unlocked.

A leg device supports an object to be able to adjust a height thereof. The leg device includes a leg shaft with a male screw portion, and an elevation body supported on the leg shaft to move upwardly and downwardly. The elevation body has a fixing portion to be fixed to the supporting object, a base portion with a through hole for the leg shaft, and a lock body portion having an upper end rotatably assembled on the base portion and a lower portion with a female screw portion engaging the male screw portion on a front surface thereof. The base portion has an elastic piece contacting a backside surface of the lock body portion, so that the female screw portion of the lock body portion is pushed against an outer peripheral surface of the leg shaft passing through the through hole.

A leg device includes a leg shaft with a male thread section having a contact section at a lower end thereof, and an elevating part supported on the leg shaft to be capable of rising and lowering. The elevating part includes a base section having a portion to be fixed to an object, a through hole for inserting the leg shaft, and a locking piece integrated with the base section at one end thereof. The locking piece has a female threaded section on a front surface of the other end thereof for engaging the male threaded section of the leg shaft, and an operation knob on a rear surface of the other end. The base section and locking piece are integrally formed to position the female threaded section of the locking piece inwardly beyond an outer surface of the leg shaft passing through the through hole.

摘要:
A grommet for fixing an object such as a cable along a groove portion of a channel-type steel material can be fixed or freely stopped by using lips of the channel-type steel material. A grommet includes a base leg portion and a flange portion. The base leg portion includes elastic leg pieces elastically protruding toward an outside, bent toward an inside by being pressed by lips when inserted into an inside of a space of the lips, and restored to original state inside a groove portion after passing through the inside of the space of the lips so as to sandwich the lips between the elastic leg pieces and the flange portion from an inside and an outside. At least either one of the base leg portion or the flange portion includes a locking device for locking the object or a locking device of the object.
