Title: Cassette tape recorder
Inventor: OOISHI KENGO
IPC: G11B27/30
Filed: 1981-06-17
Abstract: PURPOSE: To alow an optimum process of the information of another kind, by recording the address signal which is selected and set according to the contents of the recording and changing the speed of a tape to the reproducing speed as soon as the retrieval of an address is over in the reproduction mode.  
     CONSTITUTION: An address is set by operating an address key 43 in accordance with the contents of the recording, and the coincidence is obtained between the count value of a counter 40 which counts the divided clocks and the value set by the key 43. Thus an address output switch circuit 38 is controlled via a comparator 41. As a result, the clock of a clock oscillator 36 corresponding to the set value is recorded on a magnetic tape 10 in the form of the address signal corresponding to each contents of the recording. The tape 10 is forwarded fast in the reproduction mode, and the desired address signal is retrieved in the same way. Thus a speed switch circuit 50 is controlled by the comparator 41 as soon as the retrieval is over with the address signal. The tape 10 travels at the reproducing speed. As a result, a cassette tape recorder can perform an optimum process for a different kind of information.

Title: Liquid detecting device
Inventor: NAKAMURA KAZUO
IPC: G01N21/41
Filed: 1984-05-09
Abstract: PURPOSE:To detect whether a prescribed liquid exists or not with regard to a set position, and also to discriminate and detect a kind of the liquid by detecting a variation of a transmission rate of a light for reaching a photodetecting means from a light emitting means based on a refractive index which a liquid existing in a liquid flowing space has. CONSTITUTION:Negative meniscus lenses 1, 2 are provided so that concave surfaces are opposed to each other, and a space 3 through which a liquid flows is formed. Optical fibers 5, 6 are placed so that each end face 5a, 6a becomes a focal position of the meniscus lenses 1, 2. A light which is outputted from a light emitting part of a detecting circuit 7 and is transmitted by the optical fiber 5 is emitted from the end face 5a, and made incident on the end face 6a of the optical fiber 6 through the space 3 and the meniscus lens 2. When the space 3 is filled with a liquid, since a refractive index of the liquid is roughly equal to a refractive index of the meniscus lenses 1, 2, a light is converged completely to the end face 6a of the optical fiber 6, and a transmission rate of the light becomes large. On the other hand, when the liquid does not exist but air exists, the light passing through the space 3 is dispersed and not converged enough to the end face 6a of the optical fiber 6, and the light transmission rate becomes small.
