Abstract: A method for checking quality of a heat exchanger includes the steps of: performing a liquid pressure test for the heat exchanger including a first flow path and a second flow path adjacent to the first flow path by filling the first flow path and the second flow path with a liquid in a pressurized state; discharging the liquid from the first flow path and the second flow path; and promoting evaporation of the liquid remaining in the first flow path and the second flow path by reducing pressure inside each of the first flow path and the second flow path using a vacuum pump. The step of promoting evaporation of the liquid is performed to feed heated gas into the first flow path and the second flow path.

Abstract: Provided is a button fastener-side die. The button fastener comprises an annular base defining an opening and a plurality of legs. The button fastener-side die includes a holding part for holding the button fastener and a correcting member for passing through the opening of the button fastener held by the holding part, a pushing member for pushing the correcting member to move in a passing direction toward passing through the opening of the button fastener, and a first spring disposed between the correcting member and the pushing member. When at least one of the legs of the button fastener is in an abnormal position, the correcting member corrects the abnormal leg(s) to be in the normal position as the correcting member is passing through the opening.

Abstract: A button fastener transfer device can detect a fastener with one or more legs are bent radially outward. The button fastener transfer device includes a transfer path for passing the fastener with the base down; a movable member movable in the transfer path for moving the fastener downstream in the transfer path; a rotation applying part capable of contacting the fastener moving in the transfer path and configured to rotate the fastener in the circumferential direction of the base; at least one first conductive member and at least one second conductive member, which are normally electrically isolated from each other; a detection part configured to detect a non-normal fastener having at least one non-normal leg bent radially outward; and an energization mechanism configured to cause an electric current to flow between the first conductive member and the second conductive member if the detection part detects the non-normal fastener.

Abstract: An attaching apparatus, which attaches an attachment object to a fabric using a fastening member, includes at least one pair of first holding members configured to hold an attachment object; and a first die configured to hold the attachment object at a terminal of a die main body. The first die moves such that the attachment object, held at the at least one pair of first holding members, is held at the terminal of the die main body and then the attachment object is placed onto the fabric. The attachment object is transferred from the at least one pair of first holding members to the first die at a position distanced away from the fabric.

Abstract: A button indexing device used in a button attaching machine for attaching a button to be indexed in a specific orientation on a fabric of garments or the like, including lower mold provided at a button attaching position of the attaching machine, a driving section for turning the lower mold around a vertical axis, a laser beam source for irradiating a laser beam onto a point of a specified circular track of the button to be held in the lower mold around the vertical axis, an optical sensor for detecting light reflected from or scattered by the button, and a stop section for stopping said lower mold in a rotation position capable of obtaining the right orientation when said optical sensor detects the minimum or maximum amplitude.

Abstract: An air cleaner has an electric precipitating apparatus that employs corona discharge and an ozone removing apparatus downstream of the precipitating apparatus. The ozone removing apparatus has a carbon filter, and is charged with a low positive voltage to remove ozone generated by the precipitating apparatus by chemical conversion to oxygen and carbon dioxide.

Abstract: An air cleaner and an air filter for removing charged ozone in the air includes an air filter having a carbon filter for adsorbing charged ozone in an air path of the air cleaner and converting ozone adsorbed in the carbon filter to oxygen and carbon dioxide by a chemical reaction. A positive voltage is applied to the carbon filter.
