Title: Optical recording and reproducing device
Inventor: TANNO NAOHIRO
IPC: G11B7/24012
Filed: 1988-12-13
Abstract: PURPOSE:To speed up the operation of the optical recording and reproducing device with simple constitution by using an optical waveguide as a recording medium and reproducing whether or not waveguide light is scattered by a refractive index discontinuous part by plural detectors at the same time. CONSTITUTION:When reproduction is performed, the laser beam 3 from a semiconductor laser 1 for reproduction is guided from an optical coupling part 4 into an optical waveguide recording medium 5 and a part of its waveguide light 7 is scattered by refractive index discontinuous recording parts 9, 9', and 9''' to become leak waveguide light, thereby generating scattered light beams 13, 13' and 13'' outside the waveguide. The scattered light beams are photodetected by photodetectors 17, 17', 17'' and 17''' which are arrayed opposite at intervals and the output of each detector turns on and off or varies according to whether or not there is a bright point, thereby reproducing information recoded on the optical waveguide recording medium 5. The scatter efficiency per bit from the waveguide light 7 to the scattered light 13 is determined by the refractive index ratio, the depth of a pit, and the area of the ellipse at the border of the pit. When a GaAlAs semiconductor laser which generates a continuous output of 10mW is used as a reproduction semiconductor laser 1, the scattered light output per pit is about 0.1muW and sufficient detection is performed by a semiconductor photodetector.

IPC: B27K9/00
Filed: 1989-12-04
Abstract: PURPOSE:To achieve best humidification of a rush by attaching a moisture absorption agent to the body of a rush humidifier so that the agent absorbs moisture and hence its weight increases as the rush absorbs moisture and by stopping the operation of the humidifier when the humidification of the rush is in an optimum state by utilizing weight increase of the agent. CONSTITUTION:Using water vapor in an air stream having passed through a moisture generating box 1 caused by driving a fan 3, humidification begins from the side (a) of roots of a rush and reaches the end (b). A moisture absorp tion agent 5 on a sample holder 4 absorbs moisture in a manner similar to that of the rush, in which the moisture content of the agent is controlled to reach 20 % when the rush is in the best humidification state. When a container including the agent having a weight of 20 g is placed on the holder 4, a balance bar 2 inclines to the side (b) and when a weight exceeding 4 g is added to the holder 4, the balance of the bar 2 is reversed. When the weight of the agent 5 is increased from 20 g to 24 g, humidification of the rush is in a best state. Then the side (a) of the bar 2 is lowered to depress a part (c) of a bar of a limit switch 11 so that a fan 13 is stopped and humidification of the rush is completed.
