Title: Manufacture of light guide plate
Inventor: KONISHI YUICHIRO
IPC: B29C45/46
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To realize a thin light guide plate, in which uneven luminance develops a few and with which a more larger image plane can be made, by a method wherein an injection speed is made larger than the specified speed. SOLUTION: First of all, by advancing a screw 3 towards a nozzle 21 at the predetermined speed V1 so as to push a molding material in a sprue and runners. When the molding material starts to pass near the gates of a mold, the advancing speed of the screw 3 is lowered to the predetermined speed V2. After that, a speed V3, which is higher than the forward starting speed V1, is realized. Concretely, the injection speed corresponding to the speed V3 is set to be 20-100 cm<3> /s. If the injection speed is below 20 cm<3> /s, a light guide plate having a comparatively larger image plane size (or 10 inch or larger) is hard to be obtained at a high degree of area and uneven luminance tends to easily develop. The upper limit of the image plane size is preferably decided within the range, in which the fluidity of the molding material can be controlled.  However, if the injection speed is too fast, the temperature of the molding material rises rapidly due to shearing force, resulting in fearing to produce the developmental cause of silver streaks on a molding.

Filed: 1990-05-25
Abstract: PURPOSE:To avoid the action of a local stress on an inner bag member so as to prevent the breakage of a bag member, even if an outer bag member is contracted and gatherings take place on the inner bag member, by interposing a lubricant between the outer peripheral surface of the nonelastic inner bag member and the inner peripheral surface of the elastic outer bag member. CONSTITUTION:A bag member 7 for filling its contents therein is made up of three- layer structure, i.e. an inner bag member 71, an outer bag member 72 and a lubricant 73 interposed therebetween. The contents are filled in the inner bag member 71 consisting of a nonelastic film material against the elastic force of the outer bag member 72 consisting of an elastic material such as rubber, while the contents are shot out to the outside through a spray nozzle from the inner bag member 71 due to the recovering force of the outer bag member 72. Although the inner bag member 71 is contracted as the contents are sprayed out and gatherings are produced thereon, due to the provision of the lubricant 73, the contraction of the inner bag member 71 takes place in a smooth relation against the outer bag member 72 and, consequently, its frictional movement accompanied by the occurrence of an excessive stress can be prevented. Therefore, there is no breakage or the like of the inner bag member 71.

Title: Noise eliminating device
Inventor: FUKUHARA HIROSHIGE
IPC: H03G3/34
Filed: 1981-08-31
Abstract: PURPOSE:To improve the eliminating capacity of an impulsive noise eliminating circuit, by arranging a filter circuit, which stops the passage of a continuously generated impulsive noise signal when this signal is received, in the output side of a single-generated noise pulse eliminating circuit. CONSTITUTION:When a single impulsive noise signal is included in the wave detection output from a wave detecting circuit 1, the output of a noise amplifier 8 is not changed much, and therefore, the level of the amplification degree control signal of an amplification degree controlling circuit 10 is low, and a switching transistor TR 14 is turned off, and a filter circuit 11 does not function. Consequently, the held level signal of a capacitor 4 for holding the storage which is provided in the output side of a switch 3 for eliminating the single noise pulse is sent to a voice part 6 as it is. When a continuously generated impulsive noise is included in the wave detection output, the switching TR 14 is turned on, and therefore, the noise signal which passes through the switch 3 erroneously is eliminated by a low pass filter consisting of a resistance 12 and a capacitor 13 and is not sent to the voice part 6.
