Title: Gap control device for magnetic recording and reproducing apparatus
Inventor: MINOWA TOMOJI
IPC: G11B5/53
Filed: 1990-11-01
Abstract: PURPOSE:To control the amount of a gap according to a change in the relative speed between a magnetic tape and a magnetic head by including an opening and shutting plate which controls the size of an opening area for a window and a driving element which drives the opening and shutting plate to the adjusting direction of the opening area for the window. CONSTITUTION:The value of a gap between a magnetic head 3 and a magnetic tape 11 is decided by a fluid pressure. A tape levitating amount is large at the magnetic-tape entrance part at the magnetic head 3; inversely, the tape levitating amount is small at an exit part. When the magnetic head 3 enters the magnetic-tape entrance part, an impressed voltage on a piezoelectric ceramic 8 is lowered. Then, an opening area for a window 2 is expanded, and an air escape amount can be increased. When the impressed voltage is lowered at the exit part, the air escape amount can be reduced. As a result, the gap between the magnetic head 3 and the magnetic tape 11 can be controlled to be definite, a signal input/output becomes definite between the magnetic tape 11 and the magnetic head 3 and a VTR whose picture quality is high can be obtained.

Title: Method and apparatus for removing offensive odor component in exhaust gas
Inventor: AKAMA HIROSHI
IPC: B01D53/86
Filed: 1993-11-30
Abstract: PURPOSE:To provide a method for removing offensive odor components in exhaust gas which can remove the components with less energy and prevent leaking of them effectively and is suitable for treating a large amount of exhaust gas from large scale combustion facilities and others and to provide an apparatus for the method. CONSTITUTION:A heat exchanger 1 is located downstream in a flue 3; a catalyst layer 2 for a catalytic combustion method is placed upstream. An adsorbent layer is set in the heat exchanger 1. Exhaust gas passed through the catalyst layer 2 passes through a flue 5, and the flue 3 and the flue 5 cross in the heat exchanger 1. Offensive odor components in exhaust gas are adsorbed and condensed in the adsorbent layer. When the adsorption comes close to saturation, the catalyst layer is heated by the combustion in a furnace 4. Exhaust heat from the furnace 4 which was used for heating the catalyst layer 2 is absorbed by exhaust gas passing through the flue 3 in the heat exchanger 1 and transferred to the catalyst layer for the desorption of the offensive odor components by heating the adsorbent.
