Title: Speaker diaphragm made of injection foamed mold
Inventor: SATO MASATOSHI
IPC: H04R31/00
Filed: 1995-06-14
Abstract: PURPOSE: To improve the performance of light weight, high internal loss, high stiffness and environment resistance without causing cost increase. CONSTITUTION: A resin including a foaming agent is injection-molded and a 3-layer structure covering a foaming layer 3 with a skin layer 2 being a non- foaming layer is adopted. An average foaming rate over the entire speaker diaphragm 1 including the skin layer 2 which is not a foamed layer is selected to be nearly 1.1 to 3.0, the thickness of the skin layer 2 is selected to be nearly 0.05 to 0.20mm, cells of the foamed layer 3 are oriented in the broadwise direction to reinforce the skin layer 2. Since the face thickness is made thick with a low specific gravity, the diaphragm with light weight and high stiffness is obtained and since the surface is covered by the skin layer 2, excellent resistance to environment is obtained. Since it is not required to adhere three layers different from a conventional and current technology, the diaphragm is manufactured at a low cost.

Filed: 1990-06-07
Abstract: PURPOSE:To obtain economical transfer with the optimization of frequency of transferring for each transfer surface by a method wherein a residue of ink after a transferring is detected, when the residue of the ink exists, a heat transfer recording material is unwound and when it does not, a transferring is performed at the subsequent point to eliminate control of the transferring frequency. CONSTITUTION:A heat transfer recording material 3 has an intermediate layer 6 mainly composed of a resin formed on a base material 5 made of polyethylene terephthalate, polyamide or the like to improve adhering performance with an ink layer 7. With the generation of heat by a thermal head 2, the ink layer 7 melted in a heat transfer recording material 3 is transferred onto a transfer paper 8. A sensor 1 is provided in the heat transfer recording material 3 after the end of the transferring to detect a residue of the ink to judge whether a transferring surface of the heat transfer recording material 3 is usable or not. When the residue of the ink is so large to allow the transferring with the surface involved, the heat transfer recording material 3 is unwound in a direction of RF and the surface is used. When the residue of the ink is so limited to cause a degrading of quality, the heat transfer recording material 3 is not unwound but the subsequent part is used. The sensor 1, for example, employs a transmission or reflection type optical sensor to control the residue of the ink layer 7 by density.
