Title: Liquid level detector
Inventor: HATAKAWA MAMORU
IPC: G01F23/28
Filed: 1978-11-15
Abstract: PURPOSE:To increase the safety, durability and reliability, by detecting the liquid level optically through the use of optical fiber. CONSTITUTION:The end surfaces A, B of the optical fibers F1 and F2 respectively connected to the optical signal transmitter 1 and the optical signal receiver 2 are located so that they clip and liquid level L and opposed with the liquid level L with a slope angle. Thus, when the liquid level is under the broken line L', the light goes straight as the broken line arrow and is incident at the end surface B of the photo detection side fiber F2. But, if the liquid level L is between the both end surfaces A and B, the light is deflected toward the solid line arrow and it is not detected. When the liquid level is further increased and it reaches the end surface B of the photo detection side fiber F2, the light is again incident. In this case, the intensity of photo signal is weakened with the difference between air and liquid in the transmission rate. The detection of difference can make possible the liquid level upper than the set position.

IPC: G11B33/02
Filed: 1983-08-02
Abstract: PURPOSE:To avoid permanently the deformation of a cassette holder by providing a turnable cover at the opening part of the cassette holder to cover the opening part. CONSTITUTION:A figure shows movement of a cover 12, in a loading and un- loading state of a cassette tape. A cover 12 is set by a spring 13 at a position where a opening part 1c at the front part of a cassette holder 1 is covered when no cassette tape is loaded. In this case, the power is applied toward an arrow A from the upper part of the holder 1 to produce a slight warp of the holder 1. Even in such a case, just a gap is produced between the end face 12a of the cover 12 and an end face 2a of a recorder main body 2. Hereafter no larger deformation is produced with the holder 1.

Title: Water level transmitter
Inventor: OHATA SATORU
IPC: H05B3/04
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To prevent moisture from being solidified and protect an electric circuit by setting a plurality of hollow tubes transmitting a gauge pressure to a case body and arranging a heat-generating body in the vicinity of an opening of the hollow tube. SOLUTION: The water level transmitter has two hollow tubes 14, 15 in a cable 3 for transmitting a gauge pressure to a case body 8 incorporating a pressure sensor 11. An output transistor 16 is set as a heat source in the vicinity of an opening 14a of the hollow tube 14 above an electronic circuit part 12. When a front end part of the output transistor 16 is dropped into a liquid to start to measure a water level, the transistor 16 itself is turned ON. In consequence, the air in the case body 8 is warmed and rises in the hollow tube 14. The fresh outside air enters from an opening of a relay part and falls down in the hollow tube 15. The air is thus circulated in the tubes 14, 15 and changed at all times. The moisture is never solidified as a result of a temperature difference of the air in the case body 8 in the water and the outside air of the relay above the water.

Title: Synchronizing signal regenerating circuit
Inventor: SHINPO MASATOSHI
IPC: H04L7/00
Filed: 1978-11-16
Abstract: PURPOSE: To prevent malfunction due to generation of several error synchronizing signals by using counters and NAND gate.  
     CONSTITUTION: Synchronous extraction circuit 15 is connected to counters 11 and 12 equipped with preset teminals 16 and 16' through NAND gate 13 and inverter 14. then counters 11 and 12 are preset to value (a) a little bit smaller than a synchronous pattern generating period. Consequently, counters 11 and 12, when counting regenerated clock signals E to number (a), generate carry pulse H 2  to put one gate of NAND gate 13 in an ON state and pulse (l), generated when there is a string of pulses agreeing with a (m)-bit synchronous pattern in a string of regenerated pulses, is inputted from synchronizing signal extraction circuit 15 to the other gate of NAND gate 13. Consequently, pulse K appears at the output of NAND gate 13 and counters 11 and 12 are initialized, generating no carry pulse H 2 . Therefore, malfunction is prevented even if a pattern equivalent to the string of synchronizing signal pulses resides in sound or music information.
