Title: Manufacture of plastic draining bag
Inventor: TAKASAKI MASASHI
IPC: B31B50/10
Filed: 1988-08-23
Abstract: PURPOSE:To increase durability of an opening cutter, and to omit a labor and a cost required when bags are peeled one by one after pore groups are opened by holding a film heated small protrusion group and a bearer, opening the pore groups, peeling the both faces of superposed films by a peeling plate, and then forming bags. CONSTITUTION:An opening roll 2 which integrally has many protrusion groups 4 on the outer surface of a metal roll 3 and an electric heater 5 inserted into a bore opened in the axial central direction of the roll 3 is employed. A supporting roll 6 made of a flexible material such as rubber is so installed as to rotate synchronously with the roll 2 while holding a film 1 to the end of the groups 4. A peeling plate is interposed between the films 1 immediately after the rolls 2, 6. The films are sequentially brought into contact with the peeling plate interposed between the films in a state that the melted parts are softened immediately thereafter to peel both the faces of the films, and the films are then applied to a bag forming machine to form bags.

Title: Hologram photographing device
Inventor: FUJIMOTO JIYUNICHIROU
IPC: G03H1/10
Filed: 1981-12-22
Abstract: PURPOSE:To produce a moire fringe hologram which contains no excessive noise, by providing a device which changes periodically the travelling direction of the light emitted from a light source and an aperture having two holes or a slit having two openings. CONSTITUTION:The light beam generated from a laser 1 is first reflected by a rotary mirror 9 and then passes through an aperture 10 having two holes. This beam is then divided by a beam splitter 3 into subject beams 11 and 11' and reference beams 12 and 12', and beams 11, 11' irradiate a vibrating subject 7. In this case, the revolutions of the mirror 9 are controlled so that the beams pass through the two holes of the aperture 10 when the vibration of the subject 7 is at its peak. As a result, a stroboscope shutter is eliminated. Thus it is possible to produce a moire fringe hologram which contains no excessive noise by one laser.

Title: Piezo-electric electroacoustic transducer
Inventor: KANAYAMA KOUICHI
IPC: H04R1/28
Filed: 1983-11-04
Abstract: PURPOSE:To attain free setting of an acoustic characteristic by providing a convex and concave on the surface of a case and regulating vibration mode of the case itself to adjust the resonance frequency of the case itself. CONSTITUTION:An electric signal from input terminals 28 and 29 acts on a piezo-electric vibrator 20 and causes the vibrator 20 to generate machine strain according to the input electric signal. The machine strain generated in the vibrator 20 propagates to a front case 23 and a rear case 26 via the support part of a metallic diaphragm 22, causing the case 23 itself to vibrate. However, the convex and concave provided on the surface of the cases 23 and 26 restrict the case vibration mode. Therefore, proper selection of degree of the convex and concave makes the control of acoustic charactetistic of a piezo-electric electroacoustic transducer possible.

Title: Impervious material and impervious method
Inventor: KOBAYASHI TATSUO
IPC: C01B33/40
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To provide an impervious material which is excellent in an impervious ability and a self-recovery ability by forming the shape of a small piece which is mainly composed of a viscous mineral having a water bloating tendency like a plate or a corrugated sheeting body. SOLUTION: The shape of an impervious material is formed into a small piece in the form of a plate or a corrugated sheeting and they are laminatingly placed one upon the other at random, thereby forming an impervious layer. The leakage water, which penetrates between the impervious materials fails to flow straightly and moves transversely between the small pieces in the layer. As a result, the water moves zigzag in the layer, which extends dramatically a passage process between the leakage water and the impervious material and further the space between the impervious materials is small so that the contact between the leakage water and the impervious material is produced to a satisfactory extent with enough time. Furthermore, since the impervious material is bloated, the impervious function and self-recovery function are embodied in an early stage.  This construction makes it possible to provide an excellent impervious ability and a satisfactory self-recovery ability even when the filling or the layout thickness of the impervious material is thin.
