Abstract: PROBLEM TO BE SOLVED: To obtain an ultra fine porous foamed body having a void density of a specific value or more, fine voids in a high void density, and a good balance of rigidity, heat insulation performance, light-weight property and others by using a plastic material containing a polypropylene resin as the raw material. SOLUTION: A foamed body having a void density of 1011 or more, preferably 1012 or more per 1 cm3 of a raw plastic material and having an average void diameter of 2 μm or less is obtained by using a plastic material containing a polypropylene resin (a propylene homopolymer, a propylene copolymer containing 50 mol% or more of propylene monomer unit, or the like) as the raw plastic material. The content of the polypropylene resin is preferably 50 wt.% or more, further preferably 70 wt.% or more, especially preferably 85 wt.% or more. It is preferable that the plastic material contains further a polyolefin elastomer. A possible example of the manufacturing method is a supercritical foaming method comprising a process in which a supercritical fluid is impregnated in a plastic material, and a subsequent process in which the pressure is quickly released to obtain a foamed body.

Title: File registering method
Inventor: HIRAMOTO MAKOTO
IPC: G06F12/00
Filed: 1988-04-13
Abstract: PURPOSE:To register files with the same file name only by one operation and to reduce the deletion of an already registered file due to malfunction by deleting a backup file when a blank area does not exist in a storage device to secure an area to be newly registered. CONSTITUTION:A processor 1 compares the size of a blank area in the storage device 3 with that of a file to be registered, and when the size of the blank area is larger, registers the file in the blank area, retrieves already registered file names, and uses a file having the same name as the already registered file name as a backup file when the file having the same name as the file name to be registered exists. When the blank area is smaller than the file to be registered, the backup file is deleted to increase the capacity of the blank area. Since files can be registered in the blank area of the storage device 3 only by one operation untile the backup area is completely deleted, operability can be improved and malfunction can be reduced. The misdeletion of a necessary registered file can be removed.

Filed: 1991-03-28
Abstract: PURPOSE:To lower the frequency of a signal impressed to a burst signal generating circuit by driving the burst signal generating circuit by using the frequency dividing signal of a clock signal, and returning to an original high-speed signal later. CONSTITUTION:A clock signal (a) having a frequency corresponding to the data velocity of a digital data signal is frequency-divided to 1/N by a synchronous 1/N counter 13, and a frequency dividing signal (f) to be outputted is inputted to a synchronous M bit pulse generating circuit 16. The circuit 16 outputs a timing generating signal (g) extending a pulse interval to the N-fold interval of the signal (a). Further, based on the signal (g), a burst signal generating circuit 17 generates a low-speed burst signal (h) of M bits and the signal (h) is returned to the original high-speed transmitting signal by an N-fold velocity change circuit 15. In this way, a burst signal (j) having original data transmission speed is obtained from an output terminal 18. Thus, the burst signal generating circuit 17 can be operated at a frequency lower than the frequency of the clock signal (a) only by the 1/N component.
