Inventor: IMANAKA TOSHIYUKI
IPC: F24F13/30
Filed: 1995-04-04
Abstract: PURPOSE: To provide a temporarily clamping structure for a heat exchanger in which the fan replacement with high operability and reliability can be performed. CONSTITUTION: In a heat exchanger 14, the upper ends of heat exchanging units 14a, 14b are brought into contact with each other and the lower ends are separated in a 'truncated chevron' shape. The longitudinal reinforcing tube side is mounted at a mounting plate 29 by a supporting screw 16, while the flanges 21, 22 of the opposite side are mounted at mounting plates 27, 28 by screws 17 to 20. When a fan in a space is replaced, the entire exchanger 14 is rotated at an angle θ at the screw 16 as a center, and the exchanger 14 is temporarily clamped at the plate 27 by a cutout 23 and the screws 17. As a result, in the case of replacing the fan, it is not necessary to hold the exchanger 14 by one hand, and the operability is largely improved.  In the case of rotating the exchanger 14, an external force is not applied to the tube, and gas leakage from a flare is prevented to improve the reliability.

Filed: 1987-03-31
Abstract: PURPOSE:To reduce the size of a device without specifically requiring an operation lever for attaching and detaching a heat roller and press roller by providing a carrying handle for attaching and detaching a pair of the rollers freely turnably on a device body. CONSTITUTION:The carrying handle 36 is freely turnably provided on one side part in the device body. An operator holds a gripping part 38 of a handle 36 and turns the same in the direction of an arrow when paper P is jammed between the heat roller 31 and the press roller 32. A projecting part 39 pushes down one end part of a supporting lever 33 against the energizing force of a spring 35 when the handle 36 is turned. The lever 33 is then turned downward around a fulcrum shaft 34. The press roller 32 is thereby detached from the heat roller 31, by which the paper P can be removed. Since the handle 36 is used commonly as a lever for attaching and detaching the press roller, the number of parts is decreased and the size of the device body is reduced.

IPC: H04N5/92
Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To record audio and video data by compensating a difference of a delay time between compressed video data and non-compression audio data without the need for a delay memory. SOLUTION: A pack circuit 180 stores compression video data received with a delay with respect to non-compression audio data to four sectors in order in a memory circuit 16. On the other hand, the pack circuit 180 stores audio data to an idle area of a preceding sector to the compression video data, in order to compensate a time required for compression coding processing. When the pack circuit 180 stores the compression video data corresponding to the audio data stored in the idle area precedingly, an external code encoder 184 moves the audio data in the idle area to a prescribed area of a recording block to add an error correction code (external code). The audio data with the external code added thereto and the compression video data are recorded on a VTR tape 2.
