Title: Synchronizing signal extracting circuit
Inventor: HOUSHI TERUO
IPC: H04L7/04
Filed: 1982-04-21
Abstract: PURPOSE:To extract a synchronizing signal with good accuracy, by detecting the rise and fall of a pulse train including an information signal having random width and the synchronizing signal of a prescribed width, generating the 1st and the 2nd pulses when a voltage being a prescribed level or over is generated, and adding the pulses. CONSTITUTION:The synchronizing signal of prescribed width from an input terminal 1 and a pulse train including the information signal of random width narrower than the synchronizing signal are applied to detection circuits 2, 3, and the rise and fall of the pulse train are detected. The detected output is applied to voltage generators 4, 5, and when the output of the generators 4, 5 is a prescribed level or over, the output is generated from peak value passing circuits 6, 7. The output passing through the circuits 6, 7, is applied to an addition circuit 10 via the 1st and the 2nd interfaces 8, 9. The pulses passing through the circuits 6, 7 are added at the circuit 10 and only the synchronizing signal is extracted with good accuracy.

Title: Optical head for photomagnetic recording device
Inventor: SUZUKI SEIZO
IPC: G11B11/10
Filed: 1986-03-26
Abstract: PURPOSE:To reduce the number of parts, to simplify constitution and to easily miniaturize a device by providing a system detecting light read out of a photomagnetic recording medium with a birefringence plate and obtaining a differential output. CONSTITUTION:The birefringence plate 40 is arranged by tilting 45 deg. with respect to the incident angle of light from the photomagnetic recording medium, and light receiving elements 42 and 44 independently detect an S polarization component and a P polarization component, both of which the plate 40 splits. The outputs detected by the elements 42 and 44 are inputted to a differential amplifier 46 to detect a differential output, and digital information is read out. Thus, such a complicated constitution is unnecessary that a half prism and a photodetector are combined, and only one birefringence plate 40 can obtain a differential output. Therefore the number of parts is reduced to simplify the constitution, and the device can be easily miniaturized.

Title: Voice amplitude limiting amplifier
Inventor: OOYAMA TAKEKATSU
IPC: H03G9/02
Filed: 1980-05-23
Abstract: PURPOSE:To increase the hearing performance and improve the distortion factor at the bass, by extracting separately the treble and the base of an aural signal and then detecting the amplitude to control an amplitude limiting amplifier after setting the attack time and the recovery time. CONSTITUTION:The output of a preemphasis circuit 1 is amplified by an amplitude limiting amplifier 2, and both the bass and the treble are extracted out of the output through a low-pass filter 7 and a high-pass filter 8. This output is detected by amplitude detecting circuits 5a and 5b to detect the amplitude, and this amplitude is supplied to the attack/recovery time setting circuits 6a and 6b. Then the amplifier 2 is controlled by the attack time (rise time constant) and the recovery time (fall time constant) which are set optionally. During an attack time, the treble receiving no amplitude limitation is clipped by a clipping circuit 3 via a high-pass filter 9. In such way, both the treble and the bass are processed separately to improve the distortion factor at the bass without impairing the treble. Thus a hearing performance can be increased.

Abstract: PURPOSE:To prevent a short water passage in a group of ices from being formed and to enable a high cold water cooling efficiency to be kept by a method wherein a partition member is moved up and down in correspondence with a vertical variation in water level of stored cold water in such a manner that a group of stored ices is positioned higher than a water surface of the stored cold water in a cold water storing region. CONSTITUTION:In the case that a group A of stored ices is to be kept at non- immersed state against a stored cold water W, a stored amount of the group A of ices is high at an initial period of ice storing and in turn a stored amount of cold water is less and its water level is low, a partition member 5 is positioned at a higher level than the water level in the state in which the partition member 5 is moved lower than a maximum ascending water level in a cold water storing region 1w. With such an arrangement as above, an ice group storing region 1a becoming non-immersed state against the stored cold water W is assured higher the partition member 5. Accordingly, the group of stored ices is kept at non-immersed state against the stored cold water, a formation as well as a growth of a short water passage in the group of ices can be prevented.
