Title: Shaped laminate and its production
Inventor: KATAOKA HIROSHI
IPC: B29C35/00
Filed: 1978-05-12
Abstract: PURPOSE: A plurality of resin layers are laminated so that these orientations are made different from those of the adjacent layers, thus increasing shaped laminates in impact strength and toughness.  
     CONSTITUTION: In an example, a thermally plasticized synthetic resin as polymethyl methacrylate is injected through film gate 9 into the center of the cavity formed by fixed mold 8 and movable mold 13 to form layer 1 of flat plate 15  oriented in the direction of arrow 11. Then, mold 13 is moved backward to expand the mold and form a new cavity. The synthetic resin is charged through runner 14 and film gate 10 into the new cavity to form layer 2 oriented in the direction of arrow 12, thus producing objective laminate.

IPC: G06F3/06
Filed: 1987-03-10
Abstract: PURPOSE:To omit the closing process for assurance of data and to improve the writing process performance by opening a film at the time of a system rise and updating the end pointer set on a back-up memory for each writing process. CONSTITUTION:When a file set on a disk or a floppy is managed, the file is first opened and the name of the file is sent back to an open main body. Then a back-up memory is read and it is checked whether the name of a file equal to the opened file is registered or not into the back-up memory. If so, it is confirmed that a closing process is normally carried out and cleared. If not, both the file name and an end pointer set on a file label are written into the back-up memory and the end pointer is changed. Thus the closing process for assurance of data can be omitted.

The signals 102 and 106 are compared by a comparator with each other, and when the signal 108 is high, a D signal 116 which leads the signal 104 by 45 deg. is outputted. Further, the signal 102 is inverted and amplified 110 and the resulting the inverse of A signal 111 and signal 116 are compared 112 with each other, so that when the signal 106 has a higher voltage level, a C signal 113 which leads the signal 104 by 125 deg. is outputted.

The negative pressure in this passage 12 is regulated by the air from an orifice 11, and transmitted to a negative pressure chamber 21 of the second control valve 30. When this valve 30 is opened, a negative pressure in a Venturi tube 22 is transmitted to the negative pressure chamber 8 of the control valve 7 for increasing the opening degree of the control valve 7. Another passage with the second check valve 28 is provided to bypass the second control valve 30, and the opening degree of the valve 7 is increased even for a sudden increase of the negative pressure.
