Abstract: A blower configured to circulate cold air inside a body of a refrigerator. The blower includes a casing, an impeller accommodated in the casing, and a support member configured to support the impeller against the casing. The impeller includes a disk-shaped base plate rotatably supported by the support member. The casing includes an inner circumferential surface extending so as to gradually move away from an outer circumference of the base plate toward a rotational direction of the impeller at a predetermined position around the outer circumference of the base plate, and a first case flow path between the inner circumferential surface and the outer circumference. An introduction port configured to introduce the cold air to a second case flow path branched from the first case flow path is formed on the inner circumferential surface of the casing.

Abstract: The host computer of a product manufacturer (1) is provided with a back order database (12) containing order information and back order information, a procurement order database (13) containing procurement order information and a production control database (14) containing production schedule information and delivery date information to manage information integrally, and the host computer of the product manufacturer (1) and the terminals of part makers (3) are connected by leased communication lines for information exchange. The part makers (3) are able to retrieve directly information contained in those databases (12, 13, 14) through the leased communication lines, and are able to enter directly production schedule information and delivery date information into the production control database (14) by means of a received order managing means (15).

Abstract: A parts delivery reminding system includes a computer connectable to a telephone and/or a facsimile of an ordering party for parts via a telephone line. The computer assigns a received order number to each of parts so ordered, so as to control a received order for parts. After the received order number has been inputted from the telephone or the facsimile, the computer stores a voice inputted through the telephone and/or an image inputted through the facsimile while matching the voice and/or the image to the received order number, and sends the voice and/or the image and the received order number matched with the voice and/or the image to another computer.

Abstract: A separable rotary tool adapter consists of a low-speed rotary unit (A) having casings (1, 2); a first rotary shaft (3) in the casing connectable to a driving shaft of the machine tool and a second rotary shaft (5) orthogonally drivingly connected to the first shaft; a high-speed rotary unit (B) having a casing (15) detachable to the casing of the low-speed rotary unit (A); a rotary shaft (20) in the casing of the high-speed unit having a free end portion (23) connectable with a rotary tool; and a planetary roller mechanism having two parts engageable with and disengageable from each other in the axial direction, each part being cooperatively associated with one of the high-speed rotary shaft and the second rotary shaft. In the low-speed rotary unit (A), a first part of the planetary roller mechanism is attached to the second rotary shaft (5) engaged with the first rotary shaft (3) at right angles via a transmission mechanism and includes planetary roller driving retainers (9) or shaft pins (10).
