Title: Magnetic recording and reproducing device
Inventor: SASAKI YOSHIYUKI
IPC: G11B20/06
Filed: 1989-12-20
Abstract: PURPOSE:To eliminate erroneous detection by providing a circuit for expanding an amplitude during a period of synchronizing signal of a video signal, an FM modulating circuit having its enough linearity, an AM detecting circuit and a circuit for separating the synchronizing signal in comparison between its amplitude and a reference value. CONSTITUTION:The video signal with the synchronizing signal expanded in amplitude is obtained by the synchronizing signal expanding circuit 2, and is FM modulated by the FM modulating circuit 5 having enough linearity via a preemphasis circuit 4 and then recorded on a magnetic tape 8. The regenerative signal is sent to the deemphasis circuit 12, and simultaneously an envelope of the regenerative FM signal is detected by the AM detecting circuit 13, and is sent to the regenerative synchronization separating circuit 14 composed of a comparator, where the synchronizing signal at a larger envelope level than a reference value is detected. Now, if a drop-out is generated, the envelope level is diminished, and a comparator is not in excess of the reference value, so that the erroneous detection by taking the synchronizing signal for the regenerative signal does not take place at all.

Abstract: PURPOSE:To effectively perform the removal of residual chlorine in water and the rising of pH to a neutral region by using a granular medium consisting of a linear ethylene/alpha-olefin copolymer and cristobalite. CONSTITUTION:A granular medium 2 with density of 1.04-1.65g/ml is prepared by compounding 100 pts.wt. of a linear ethylene/alpha-olefin copolymer with density of 0.910g/ml or less prepared according to a gaseous phase low pressure method and 20-250 pts.wt. of cristobalite. Waste water containing various contaminants is sent to an upper chamber 1D from a waste water supply port 1G and passed through a net 1B while agitated by barrier plates 1J arranged over a proper number of stages to flow down to a granular medium receiving chamber 1E having the granular medium 2 received therein. Herein, the granular medium 2 forms a fluidized state by the flowing down waste water and the air from an air pipe 1N and the contaminants in the waste water are adsorbed on the granular medium to be grown into coarse particles. These adsorbed grown contaminant particles are released from the granular medium 2 because the granular medium 2 is agitated in a fluidized state.

IPC: A61B5/117
Filed: 1989-12-25
Abstract: PURPOSE:To obtain a finger image of high quality by attaching a warming means to the attaching face of a finger placing base with a wedge-shaped member between them. CONSTITUTION:A heater 15 is adhered to a face R of a prism 11 with a wedge- shaped member 16 between them and is attached at an angle to the attaching face R of the prism 11 by this wedge-shaped member 16. When the temperature of a finger placing face T of the prism 11 is raised to the value required for sweating after the start of warming of the prism 11, a finger F is placed on the finger placing face T. Since the heat from the heater 15 approximately simultaneously reach the face T by the wedge-shaped member 16 in this case, the temperature distribution on the finger placing face T is approximately uniformized. Consequently, the finger F equally sweats, and uneven contact of the finger F to the prism 11 is prevented. Thus, a vivid and uniform finger image including the fingerprint or the like is obtained.
