Title: Polypropylene film having small curvature and manufacture thereof
Inventor: KUWABARA KAZUTO
IPC: B32B27/32
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To resolve the voblem of uninformed sagging and improve a workability by a method wherein the orientation angle of a film and its longitudinal dimensional difference represented by the specified formula are respectively set to have specified values. SOLUTION: In a laminated film with the predetermined thickness, which is produced by laminating one or more selected from the group consisting of a polypropylene film with a small curvature, especially an ethylene-vinyl ester copolymer, an ethylene-acrylic copolymer or the like, a cold shrinkage difference at an aging stage after winding-up of the film at manufacturing is reduced. In other words, the curvature of the film developed due to the cold shrinkage difference or the difference between the cold shrinkage of the film at its edge, which is small, and that at its central part, which is large, is reduced.  The orientation angle of the filn is set to be 7 deg. or more and a longitudinal dimensional difference Z represented by the formula: Z=0.0008 (l/mm)×A×B, (in which A is the width in mm of a product and B is the amount in mm of a curvature) is set to be in a range of 15 mm or less. If the dimensional difference Z exceeds 15 mm, the development of a large number of products, one side of each of which sags due to working, on the surface of each of which wrinkles develop or the like so as to make products unusable, is solved and the post-workability of the laminated film can be improved.

Title: Method and device for providing alternative communication network
Inventor: BEGEJA LEE
IPC: H04M3/12
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To perform a service through an alternative local network by using power provided in an existing local exchange carrier. SOLUTION: A media selection device 1 functionally and parallelly connects an alternative local carrier network 3 and an existing local exchange network 4. When the loss of local power is detected, the device switches a subscriber handset 9, etc., from the network 3 to the existing network 4 based on the assumption that the network 4 can operate even if some loss of the local power occurs. While power is supplied to the device 1, a call out is transmitted from the handset 9, etc., to the network 3 through the device 1, and a call from the network 3 is transmitted to the handset 9, etc., through the device 1. Also, a sending or receiving call can be connected to the network 4 without disturbing the telephone service on the network 3. The difference of dial tones shows which network is currently used.

Title: Negative pressure type secondary valve operating device for dual carburetor
Inventor: ADACHI HIDESHI
IPC: F02M11/02
Filed: 1987-02-27
Abstract: PURPOSE:To prevent the lean fuel mixture transiently generated when a secondary valve is not opened quickly during the cold quick acceleration by providing a leak passage communicated to the upstream of a choke valve on the negative pressure chamber of a secondary valve operating device. CONSTITUTION:A leak passage 23 communicated to a communicating hole 22 at the upstream of a choke valve not applied with the pressure loss by the choke valve 4 is provided on the negative pressure chamber 19 of a secondary valve operating device 12. An orifice 24 with a cross section area smaller than that of the orifice 21 of a negative pressure passage 20 guiding the Venturi negative pressure to the negative pressure chamber 19 is provided on the leak passage 23 to limit the leak quantity. Since a choke valve 9 is hardly opened during the cold operation, the negative pressure generated in a large Venturi section is made large as compared with the fully opened state of the choke valve 9 after the warming up, but the leak passage 22 is provided, thus the leak quantity is increased by the amount of the pressure loss of the choke valve 9 than that during the warming up, and the negative pressure applied to the negative pressure chamber 19 is reduced. Accordingly, the lean fuel mixture transiently generated during the quick acceleration is prevented, thus the good operability with no P-S stumble or the like can be obtained.

Title: Epoxy prepreg
Inventor: KADOTANI KENZOU
IPC: C08J5/24
Filed: 1979-04-11
Abstract: PURPOSE: Epoxy prepregs prepared by laminating glass nonwoven fabrics on both sides of a specific core are used to form insulating layers safe even when excess current flows in a coil.  
     CONSTITUTION: On both sides of hard paper of aromatic polyamide with a density of 0.7W1.0 g/cc are plied glass nonwoven fabrics, then they are impregnated with epoxy resin at 80°C and the resin is semicured by heating at 120°C for 5 min, thus forming three-layered prepregs. The prepreg is inserted between coiled conductors to form insultating layers so that the adhesion between the conductors and the glass nonwoven layer is higher than the share strength in the core and the sliding wear of the insulating layer can be prevented because release occurs in the core even when a large share stress is applied by an accident such as excess current.

Filed: 1986-02-27
Abstract: PURPOSE:To prevent take-up torque from increasing unnecessary by returning a mirror driving mechanism and an automatic stop mechanism quickly in the initial stage of film take-up operation by the rotation of a motor after a shutter mechanism finishes operating. CONSTITUTION:A figure (a) shows that shutter charging operation and film take-up operation are completed, an SW S6 is off, and changeover SWs S2 and S3 are changed over so as to rotate a motor M in a mirror-up driving direction. Then when a release SW S1 is turned on, only a lower circuit operates to start mirror-up motor and the SW S5 is turned off through the operation of a mirror-up limiting lever after the mirror-up motion (figure (c)). Then, the SW S6 is turned on by a one-turn limiting lever while the SWs S2 and S3 are changed over to film winding sides so that the motor M rotates, the film winding operation is started (figure (d)). The SW S5, on the other hand, is turned on through the rotation of the mirror-up limiting lever, but an SW S4 is turned off by the one-turn limiting lever and a mirror-up circuit does not operate. A mirror is returned in the initial stage of the winding operation, so the take-up torque never increases.
