Title: Disk for optical memory
Inventor: MOROZUMI SHINJI
IPC: G02F1/1337
Filed: 1984-05-23
Abstract: PURPOSE:To extend the life of a laser system, by using a liquid crystal material as the storage material of the domain forming pattern of a disk for optical memory. CONSTITUTION:A thin-film metallic layer 11 to be used for providing a reflecting surface is formed on a substrate 10 made of glass, plastic, etc., and liquid crystal molecules 12 are regularly arranged in X-axis direction on the layer 11. When the deflected wave surface of writing laser lights is inputted in a specific spot under the condition shown in Fig. (a), part of the liquid crystal molecules 12 is disturbed in orientation and becomes the condition shown in Fig. (b). Reading laser lights are irradiated upon the disturbed liquid crystal molecules 13. The deflected wave surface of the reading laser lights is in X-axis which is the same as the arranging direction of the molecules. The laser lights are scattered and distributed in various directions and only 10% or less quantity of the lights returns to a pickup located above. On the other hand, the laser lights made incident on the liquid crystal molecules 12 which are not distributed in orientation are reflected by the reflecting surface 11 and almost all quantity of the lights is returned to the pickup as shown by Fig. (c). Therefore, the optical characteristic changes at a low temperature and the stability can be maintained for a long time.

Title: Manufacture of cone-type boron-diffused diaphragm
Inventor: SAITOU TATSUO
IPC: H04R7/12
Filed: 1978-08-28
Abstract: PURPOSE:To eliminate the wave-type winding by forming the flange by bending the outer circumference of the diaphragm and then cutting the flange after a high- temperature heat treatment for the boron diffusion. CONSTITUTION:The outer circumference of diaphragm 5 composed of the titanium metal or the like is bent to form flat flange part 8 into a body with diaphragm 5. Fall part 7 is provided at the neck part of diaphragm 5, and at the same time flange part 8 is formed in a body at part 7. Furthermore, flat flange part 6 contains circular projected groove 9 formed. Diaphragm 5 thus formed undergoes a high- temperature treatment for the boron diffusion, and then the flat flange part is removed by the press cutter or the like. In such way, no wave-type winding occurs  at the outer circumference of the diaphragm, thus omitting the correction work  for the winding malformation to enable a direct edge adhesion at the diaphragm  outer circumference. As a result, the quality of the diaphragm can be enhanced.
