Abstract: No studies have been made regarding what kinds of refrigerants should be used in a refrigeration cycle device for a vehicle. An air conditioner (1) for a vehicle includes a refrigerant circuit (10) and a refrigerant that is sealed in the refrigerant circuit (10). The refrigerant circuit (10) includes a compressor (80), a first heat exchanger (85), which serves as a heat dissipater in a dehumidifying heating mode, an outside-air heat exchanger (82), a cooling control valve (87), and a second heat exchanger (86), which serves as an evaporator in the dehumidifying heating mode. The refrigerant is a refrigerant having a low GWP.

Abstract: The invention is aimed at preventing bottom crack from occurring in a peelably laminated plastic container and maintaining the container stably in good in-use condition. This can be achieved by increasing the anti-peeling strength of a pair of rib strips, with which the bottom rib is formed, in the bottom seal that has been obtained by pinching off the parison at the bottom and molding the parison into a blow molded, peelably laminated plastic container. The bottom seal 13 of a blow molded, peelably laminated container 1 is reinforced by a pair of rib strips 14 which are pressed to each other to form the bottom rib 15. A multiple number of cavities 16 are formed in the bottom rib 15 in such a way that the rib strip 14 on one side is pushed toward, and caved into, the rib strip on the other side at several points, and vice verse. An expanded portion 18 is formed in the ceiling of each cavity 16.

Abstract: A paper feeder is removably attached to an image forming apparatus having a document setter in which a document to be copied is set. The feeder feeds copy paper to the image forming apparatus. A document detector is mounted on one lateral side of the document setter of the image forming apparatus in a position facing a corresponding lateral side end of the document. The document detector detects whether the document is set properly in the document setter. A determining arrangement determines the presence or absence of the document in the document setter on the basis of the detection result of the document detector. A warning arrangement notifies an operator of an error in setting of the document, in the absence of a determination of the presence of the document.

Abstract: A paper feeder is removably attachable to an image forming apparatus and has a display unit. The number of copies displayed on the display unit is incremented when copy paper reaches a specified position in the path of transport. The paper feeder includes a paper feed for transporting the copy paper to the apparatus, a reference distance memory for storing therein a reference distance from a predetermined feed position of the paper feed to the specified position in the apparatus, a device for measuring the length of the copy paper transported from the predetermined feed position, a counter for checking whether the length measured by the measuring device has reached the reference distance and for incrementing the number of paper sheets fed to the apparatus upon the length of transported paper reaching the reference distance, and a display for indicating the number of paper sheets counted by the counter.
