Title: Device for heat sealing tube-like packaging material
Inventor: HAYASHI KOJIRO
IPC: B65B51/22
Filed: 1990-10-19
Abstract: PURPOSE:To prevent the edges of a seal part on the inside of a container from heating to an unnecessary temperature by a method wherein two strip like magnetic substances are provided outside two straight parts extending along the full length thereof, projections are provided extending lengthwise of the straight parts at the four places thereof adapted to apply a high pressure and the projections are formed into an arcuate cross sectional contour. CONSTITUTION:A pair of opposing pressing members 23 and 24 is fixed to the upper part of a pair of freely rockable arms 21 and 22 and the pressing member 24 is provided with a copper-made, U-shaped high frequency coil 27 having two straight parts 25 and 26 extending parallel to each other and with two strip-or plate-like ferrite-made magnetic substance 28. The projections 43 with arcuate cross section formed on the pressing surface 42 of the high frequency coil 27 press both edges of a tube with a high pressure upon sealing. The existence of the magnetic substance 28 on the outside of the coil 27 causes the magnetic line of force attempting to diffuse outwardly of the coil 27 to refract in the direction of the magnetic substance 28. For this reason, the parts of packaging material outside of the coil 27 become difficult to heat.

Title: Display system
Inventor: NAKAZATO HIDEAKI
IPC: H04N5/232
Filed: 1990-10-20
Abstract: PURPOSE:To prevent a picture from being displayed ruggedly by allowing a scanning conversion section to delay image pickup information of two-preceding field and to read the information depending on a shift from a display deviation correction quantity calculation section and displaying the information as if the information were picked up at the same time when the image pickup information of one preceding field is picked up simulating. CONSTITUTION:A field memory 36 by three fields is provided, one field is used for write and the remaining two fields are used for read. A picture data picked up at one-preceding field is stored to one of the two fields of the read use memory, and a picture data picked up at two-preceding field is stored to the other. When a read address of the memory in the two read field memories storing the picture data picked at 2-preceding field is deviated by 64 picture elements, the data is read as the picture data simulatingly picked up at one- preceding field. Thus, even when a visual axis of an infrared ray image pickup device is deviated with respect to an inertia space, no ruggedness is caused in the picture of longitudinal lines.

CONSTITUTION:At the time of down-shift from high speed stage to low speed stage, first a frictional engagement element F2 for high speed stage is released to change a gear ratio, and on reaching a set value for low speed stage, a frictional engagement element F1 for low speed stage is connected. At this time, the slippage of the frictional engagement element F2 for high speed stage is feedbacked to retain a gear ratio for low speed stage until the frictional engagement element F1 for low speed stage is completely connected, so that it is possible to prevent a sudden gear ratio change at a point of time the frictional engagement element F1 for low speed stage is completely connected. Accordingly a gear ratio can be smoothly changed at the time of down-shift, so that a speed change shock can be prevented or reduced so as to remarkably improve riding comfortableness.

Filed: 1993-10-20
Abstract: PURPOSE:To provide an electron tube equipped with a cathode structure with improved life. CONSTITUTION:A rotating tab is arranged, in the direction of tangent of the cross section of the cylinder around the cylinder of the sleeve 20 having the electron radiating matter 7 of a cathode structure for an electron tube at its apex, to abut on the sidewall of a ceramic base 5 only when the tip of the rotating tab 12 thermally expands accompanying the lighting of a heater 9 for radiation of electron.
