Title: Drive method of magnetic bubble
Inventor: SUGA SEIICHI
IPC: G11C19/08
Filed: 1985-01-24
Abstract: PURPOSE:To suppress a rise in the temperature of a magnetic bubble element, to widen an acting temperature range and to obtain the drive method of the magnetic bubble for improving the reliability of an action by impressing alternately two unipolar pulse magnetic fields having different directions as an in-plane magnetic field. CONSTITUTION:In order to obtain two pulse magnetic fields in different directions by synthesizing magnetic fields generated by two coils for intersecting orthogonally each other, the first 1/2 period and a latter one are different in terms of current amplitudes of an x coil current 12 and an y coil current 13. In case of a drive method for using a conventional rotary magnetic field, it is necessary that DC x and y coil currents having maximum amplitudes at the same level are shifted by 1/4 period and impressed on the coil, and their maximum amplitudes are more than a coil current for generating a pulse magnetic field. Compared with the rotary magnetic field drive, the pulse magnetic field drive can reduce the coil current, whereby the power consumption becomes about the half. Thus the rise in the temperature of the magnetic bubble element, which is caused by heating of the coil, is less, and therefore the acting temperature range can be widened.

Title: Debubbling tube pump
Inventor: NINOMIYA SHIYOUGO
IPC: F04C5/00
Filed: 1979-02-05
Abstract: PURPOSE: To facilitate debubbling by a method wherein the tube of a tube pump is provided with restoring property in the first half of the pressing position, while no restoring property is provided in the second half, and thereby fine bubbles produced in a liquid of a high viscosity are made large.  
     CONSTITUTION: By pressing tubes 2, 4 by roller 3 fixed on endless rope 7, liquid having a high viscosity is pushed out in the direction of motion of roller 3. Tube 2 is almost circular in cross section and it is provided with restoring property, and by the same function of dropping pipette, it sufficiently sucks the liquid. Tube 4 is made flat or closedd in its cross section and is not provided with restoring property. Consequently, bubble are made large in tube 4. For this reason, after the discharge of liquid, debubbling takes place speedily.

Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To provide a hydraulic control device of automatic transmission for vehicle, with which the down-shift of the transmission can be performed smoothly regardless of the vehicle running condition. SOLUTION: When a vehicle running condition sensing means 306 is sensing the high speed, high load running which takes a time for the input shaft revolving speed NIN to rise to the revolving speed after the shift in the mode with 4-3 down-shift command, a line pressure reducing means 316 reduces the line pressure PL by a certain value ΔPL at the time of 4-3 down-shifting, so that it is possible to delay the engagement start timing of a clutch C1. Accordingly the engagement start timing of the clutch C1 can be approached to the synchronized timing of the revolving speed to show a delay tendency in case the vehicle running is made at a high vehicle speed and with a high degree of throttle opening, compared with any other case, so that a smooth down-shift operation is ensured.
