Title: Method and apparatus for shaping surface of synthetic resin sheet
Inventor: NODA YASUYOSHI
IPC: B29C59/04
Filed: 1987-02-17
Abstract: PURPOSE:To surely and precisely shape and consequently enhance the shaping efficiency of a sheet by a method wherein an embossed pattern is transferred and shaped on the surface of the synthetic sheet by continuously feeding and pressing the synthetic resin sheet which is under plastic state to the outer surface of a shaping roll, which is gas permeable and porous and on the outer surface of which the embossed pattern is provided, through the rotation of said roll. CONSTITUTION:A first and a second press rolls 20 and 21, which serve as a pressing device with a synthetic sheet 1 wound round nearly all the circumference of a shaping roll 7, press the synthetic resin sheet 1 to the outer surface of the shaping roll 7. Thus, the synthetic resin sheet 1 under plastic state deforms so as to enter the interiors of recessed parts 9a of embossed pattern 9, resulting in continuously transferring and shaping the embossed pattern 9 onto the surface of the synthetic resin sheet 1. At this time, though the air in the recessed part 9a is pressed by the synthetic resin sheet 1, said air is not compressed, since the air escapes through a large number of vent holes 10 made on a roll part 8 to the interior of the roll part 8. Since the surface of the synthetic resin sheet 1 can go into the bottom of the recessed part as a result, the embossed pattern 9 is surely and precisely transferred.

Abstract: PURPOSE:To improve the penetration of electrolyte into small holes in the surface of a valve metal and to enhance the achieving rate of a capacitor, when solid electrolyte that incorporates the complex salt of 7,7,8,8-tetracyanoquinodimethane as a main component is attached to the valve metal having a dielectric film and formed, by impregnating the valve metal having the dielectric film with the thermal fused liquid of the solid electrolyte, thereafter applying pressure on the metal, and performing steps to cooling and solidification under the compressed state. CONSTITUTION:A film is provided on the surface of a valve metal by anodic oxidation or anodic formation. When solid electrolyte comprising the complex salt of 7,7,8,8- tetracyanoquinodimethane is attached on the valve metal and formed, the solid electrolyte is thermally fused. The valve metal is impregnated with the electrolyte. Thereafter, pressure is applied on the metal. Steps to cooling and solidification are performed under the compressed state. The solid electrolyte is penetrated into small holes in the surface which are generated by etching and the like. The covering rate with the solid electrolyte is enhanced. Thus, the achieving rate of a capacitor is improved. The larger the compressing force, the higher the penetration of the liquid into the capillary holes in the porous surface. Therefore, it is desirable that the pressure that is as high as possible is applied.

Abstract: PURPOSE:To prevent warning time from being lengthened by changing the sound starting time of an alarm unit depending on the indication of signals in the next territory when the indication of the next territory is lower in grade than the indication of signals in the previous territory. CONSTITUTION:When a train 10 enters a territory (b), a train detection device 122 outputs detected signals to the MPU 100.

And then, when the delayed time has elapsed, judgement is formed by the MPU 100 whether or not the indication of a forward signal 3 is lower in grade than the approach indication of a signal 2 based on the indicated signal from a signal control device 113. As a result, when it is, for example, found to be lower in grade, it is judged whether or not the train 10 has entered a territory (c) based on detected signals from a train detection device 123. And when the train is found to have entered, another delayed time is set up based on the indicated signal from the signal control device 113.

Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To improve the processing speed by comparing the values of variables and rearranging the values of the respective variables. SOLUTION: A large/small rearranging means 11 while adding one each to the value of a variable P from a minimum variable Min to a digit number (n-1) replaces the values of a variable Y (P+1) and the value of a variable Y (P+1) with each other when the variable Y (P+1) is larger than the variable Y (P). An increasing-order rearranging means 12 repeats the above comparing processing when the variable P is not the digit number (n-1) after 1 is added to the variable P, returns to the comparing process when the variable P is the digit number (n-1) and a decreasing-order processing is performed, and replaces the values of the variable Y (Min) and variable Y (n) with each other when an increasing-order process is performed.  Then a minimum variable value varying means 13 returns to the comparing processing when the minimum variable value Min is not (n-2) after 1 is added to the minimum variable value Min and replaces the values of a variable Y (n-2) and the variable Y (n) with each other when the minimum variable value min is (n-2).
