Title: Magnetic recording and reproducing device
Inventor: SHIMODA KENJI
IPC: G11B15/087
Filed: 1985-09-30
Abstract: PURPOSE:To attain smoothly the recording speed discrimination and the tracking control based on a pilot signal reproduced from a minute section by obtaining an error signal for tracking control and recording speed discrimination from a separate track and not specifying a head obtaining a tracking control error signal. CONSTITUTION:A pilot signal recorded to all parts of a track 1 is reproduced and a reference signal multiplied with a reproduced pilot signal is changed to obtain a tracking control error signal and a recording speed discrimination error signal from all the parts of the track 1 in order, then the effect of the recording speed discrimination error signal on the the error signal for the tracking control is prevented. Further, the tracking control error signal by the scanning of heads A, B and the recording speed discrimination error signal is obtained by the scanning of the next heads A, B. Thus, the head obtaining the tracking control error signal is not used exclusively and both the heads A, B are utilized, then the tracking control taking the head characteristic difference and the mounting error into consideration is attained.

Title: Batch-wise vacuum distillation apparatus for regenerating washing liquid
Inventor: KARAKI KAZUHISA
IPC: B01D3/10
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To easily perform washing liquid regeneration with high precision in an apparatus for regenerating washing liquid where after the vaporized raw material to be distilled is passed through a packing material in a fractionating column, it is condensed in a cooling means by providing a reflux means for liquefying and returning a part of the raw material to be distilled to the fractionating column. SOLUTION: In the case waste washing liquid after washing glass, metal or the like (a nonaqueous detergent contaminated with cutting oil: polluted liquid) is regenerated, polluted liquid is vaporized in a fractionating column 1 and also polluted liquid in a polluted liquid tank 11 is sucked into the fractionating column 1. When a heating pipe 2 is heated, volatile components of the vaporized nonaqueous solvent reach the upper part of the fractionating column 1. A part of the volatile components is liquefied by a cooling pipe 4 at the upper part of the fractionating column 1 and is returned to the fractionating column 1, and the components rich in volatility are cooled in a cooling part 6. At this time, in cooling by the cooling pipe 4, the reflux quantity to the fractionating column 1 is controlled by controlling the quantity of cooling water.  The liquefied distillate is taken out by an ejector 7 and is accumulated in a liquid sealing tank 9 as regenerated liquid.

Title: Flow velocity measuring device for flow field
Inventor: NAKAMURA HITOSHI
IPC: G01P13/00
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To provide a flow velocity measuring device, which can precisely measure a flow distribution in a short time, can measure in a rapid response even if a flow velocity is large, can measure the whole space, and has improved precision. SOLUTION: A heating member 1, which is plain-woven of metal wire rods 1a, is made to carry a current by a slidac (R) 3 supporting by a holder 2. The temperature change of the heating member 1 caused by gas flow is measured by an infrared camera 4, while the measured data are analyzed by a personal computer 5. Because the heating member 1 is a plain-woven wire netting, insertion of the heating member 1 into a flow field does not cause a large pressure loss in the flow field so that influence on the flow field such as a swirl is prevented. Further, when the heating member 1 is heated by carrying a current, the whole plain-woven wire netting evenly generates heat so that a flow velocity distribution is precisely measured.
