Title: Magnetic head
Inventor: INOUE HIROTO
IPC: G11B5/127
Filed: 1987-10-15
Abstract: PURPOSE:To prevent an S/N at the time of reproduction from being deteriorated by providing a gap part, and providing a core made of a magnetic material with prescribed width, a coil whose magnetic flux can be permitted to flow arranged on the core, and a conductive thin film being set at relation of normal plane with the thickness direction of the core and also arranged at least on a plane in the neighborhood of the gap part. CONSTITUTION:The conductive thin film 7 consisting of a conductive material is formed on the core 2 being set at the relation of almost normal plane with the direction of track width (t) and the end faces 6a and 6b of a gap member 3. By applying an electrical signal with a high frequency on the coil, a magnetic flux is generated in the neighborhood of the gap part, however, since the conductive thin film 7 consisting of the conductive material is formed on the core 2 and the end faces 6a and 6b of the gap part 3, a reactive magnetic flux due to an eddy current effect is formed, and as a result, the magnetic flux leaked from the conductive thin film 7 can be suppressed at a minimum quantity. In such a way, it is possible to improve the S/N at the time of reproduction.

Title: Improved method for dissolving gas in liquid
Inventor: RORENSU MAABIN RITSUTSU
IPC: B01D53/18
Filed: 1988-10-18
Abstract: PURPOSE: To make it possible to achieve a desired gas dissolution with a low energy requirement by using the pressure head of a liquid and combining the flow velocity of the liquid, the diameter and length of a gas-liquid contact device, the retension time in the contact device of a liquid stream contg. dispersed gas and gas dispersion conditions. CONSTITUTION: The initial dispersion of the air bubbles in the liquid is formed by injecting the gas into the stream of the liquid. The liquid stream contg. the dispersed air bubbles of a relatively low initial pressure is passed from a high level at which the uniform dispersion of the fine air bubbles is maintained and the gas injection of the formed liquid flow is executed usually in the flow passage in a downward direction. The pressure acting on the liquid stream during this downward passage increases as the static head increases and this increase of the pressure of the liquid steams leads to an increase of the dissolution rate and dissolution speed of the gas in the liquid.

Title: Moving compensation prediction inter-frame coder
Inventor: UEYASU HIROYUKI
IPC: H04N7/30
Filed: 1990-09-28
Abstract: PURPOSE:To change a quantization step size with a change of a small residual code quantity in a frame or a field with a small object code quantity by calculating the residual code quantity for each block so as to revise the quantization step size and varying the correction method of the residual code quantity based on the object code quantity per block. CONSTITUTION:A residual code quantity correction coefficient calculation section 40 obtains an object code quantity per block from an object code quantity of a frame or a field, sets a residual code quantity correction coefficient a and outputs a residual code quantity correction coefficient signal 41. Then a quantization step size calculation section 23 multiplies the residual code quantity correction coefficient alpha with a fluctuation of the residual code quantity and uses the result of the product added to the residual code quantity as a corrected residual code quantity and sets the quantization step size from the result. Since the residual code quantity correction coefficient alpha is set large when the object code quantity is small, the quantization step size is easily changed even when the fluctuation of the residual code quantity is small with respect to a small object code quantity.
