Filed: 1986-12-03
Abstract: PURPOSE:To discriminate the feeding stage depending on a ring back tone by sending a low frequency natural ring back tone at application of commercial power supply and sending a high frequency ring back tone such as a ceramic ringer at power failure. CONSTITUTION:If an incoming call is detected at the incoming call detection standby stage, a power failure detection circuit 12 starts detection of power failure and when the power failure is detected, a switch 9 is thrown to the position of the ceramic ringer 10 and an input/output control circuit 3 uses a ring back tone circuit 8 to generate a 1kHz or 1.2kHz frequency signal to drive the ringer 10. On the other hand, if no power failure is detected, the switch 9 is thrown to the position of a speaker 11, the control circuit 3 uses the circuit 8 to generate a 450 or 600kHz frequency signal to drive the speaker 11.

Title: Method for molding sleeve and sleeve formed by the method
Inventor: OGAWA KIICHI
IPC: B29C48/325
Filed: 1990-10-26
Abstract: PURPOSE:To form a striped pattern around a cylindrical base by a method wherein, when molten resin is deposited over the periphery of the cylindrical base while the base is being moved out from a through hole by the use of a die having an annular resin extrusion port around the through hole, the void where the cylindrical base contacts the molten resin is periodically reduced in pressure. CONSTITUTION:A die D includes a first sleeve 5 with a guide hole 2 and a second sleeve 6 with a through hole 3, in which a die body 7 encircles the sleeve 6 and an annular extrusion port 9 is formed around the hole 3. The internal diameter of the hole 2 is approximately equal to the outside diameter of a cylindrical base 1. The internal diameter of the hole 3 is made grater than the outside diameter of the base 1 and the hole 3 is connected to a vacuum pump P. As the base 1, an aluminum lamination tube, etc., can be employed. If resin is extruded, while the base is being moved through the holes 2 and 3, a resin layer 20 is formed over the base 1. If the vacuum pump is turned on/off periodically, thickness of the molten resin layer changes, so that striped pattern is formed. By providing two units of such devices in series, resin layers 20a, 20b can be formed over the outside surface of the base 1.

Title: Treater for expanded polystyrene
Inventor: SAKAI NORITAKA
IPC: B29B17/00
Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To provide a treater that can efficiently perform the volume reduction and regeneration of an expanded polystyrene and is reduced in size. SOLUTION: An expanded polystyrene is dissolved in a solvent to form a solution. The solution is kneaded in a vacuum with a selfcleaning kneader 3, while it is heated in the kneader. The solvent vaporized by the vacuum and heating is condensed and recovered, and the regenerated polystyrene devoid of the solvent is extruded. The extrusion can be continuously performed, which leads to improved productivity. In the self-cleaning kneader, a space is formed in the upper part of the casing, and the paddles rotate in such a manner that their margins are in contact with the inside surface of the casing, and therefore, the dissolved product is transferred while it is thinned down. When the thinned dissolved matter reaches the upper space, the contained solvent is smoothly vaporized in a vacuum because of its thinness.

Abstract: PURPOSE:To make the band pass characteristic hardly change in the state of being mountable and mounted on the surface of a mount base and by providing a prism-shaped resin layer covering the filter main body and a conductive layer shielding the resin layer. CONSTITUTION:The dielectric base 1 formed with electrode pattern 4, 5 is covered by the prism-shaped resin layer 7. A conductive layer 9 formed with a conductive paint coated thereupon is formed to the outer face of the resin layer 7. Since the resin layer 7 is formed as a prism and the bottom face is made flat, a band pass filter is mounted on the surface of the mount base such as a printed circuit board. Since at least both side faces at the coil side and the front/rear faces of the resin layer 7 are shielded by the conductor layer 9, even if an electronic component or a metallic piece exists in the vicinity at mounting, the disturbance in the electromagnetic field distribution around the filter is prevented and the pass band characteristic is hardly changed.
