Title: Television signal y/c separating circuit
Inventor: MOTOTAMA YASUKAZU
IPC: H04N9/78
Filed: 1985-06-19
Abstract: PURPOSE:To execute the separation of a luminance signal and the color difference signal of both systems of NTSC/PAL and to decrease a fact that the color difference signal leaks into the luminance signal, by changing the number of addresses and switching a signal level which is inputted to a chroma band pass filter by a switch. CONSTITUTION:C signal is outputted by two times of the C signal level of an original signal in case of NTSC and as the same level as the C signal of the original signal, in case of a PAL system therefore, by switching a switch 8, the C signal of the same level as the original signal is obtained. At the time, 0H-2H signals are inputted to a line correlation detecting circuit 10 and a line correlation is detected. A line correlation signal obtained in this circuit controls a switch 12, and in case when the line correlation is weak, a 1H signal is inputted as it is to a C signal band pass filter 11, and in case when the line correlation is strong, a C signal 9 obtained by a bomb-line filter is inputted to the C signal band pass filter 11. The output of a color difference signal band pass filter 11 is a C signal separated from a composite video signal, and also by eliminating this signal from the 1H signal, a separated Y signal can be obtained.

IPC: F16N7/26
Filed: 1979-10-13
Abstract: PURPOSE:To prevent generation of chattering noise during low speed revolution by submerging a fluid resistance application plate in a lubricating oil when the gear revolution speed of driven shaft falls below a specified value while by separating the plate from the lubricating oil when the gear revolution speed rises above a specified valve. CONSTITUTION:A constantly engaged gear 2 is fastened to a driving shaft 1 while a constantly engaged gear 3 is also fastened to a driven shaft 4.

Title: Descramble signal processor
Inventor: HOSOKAWA HIROHISA
IPC: H04N7/167
Filed: 1989-05-25
Abstract: PURPOSE:To eliminate an additional sample that may possibly give the adverse influence to a display device by switching a signal of a pedestal level at the position of the additional sample of a restored descramble video signal. CONSTITUTION:A pedestal level detector 31 detects a pedestal level with a signal S1. A restoring device 30 restores the scrambled digital video signal received via an A/D converter 2 based on a switch position 21 and a signal S2 showing an effective transmission screen. The restored digital video signal is converted into an analog signal by a D/A converter 6 via a switch 35. Thus a descramble video signal 7 is obtained. In this case, an additional sample remains in the signal obtained by the device 30 an the switch 35 is controlled by a signal S3 showing the position of the additional sample obtained by a controller 32. Then the descramble video signal 7 is switched to a pedestal level obtained by the detector 31 only at the position of the additional sample. Thus the additional sample is deleted out of the signal 7.

Title: Video tape recorder
Inventor: TAKAHASHI MINORU
IPC: G11B5/024
Filed: 1992-05-25
Abstract: PURPOSE:To prevent a cross modulation distortion component from coming within a color signal band by setting the frequency of erase signal at a predetermined high level. CONSTITUTION:Standard or high picture quality mode recording is carried out by means of a rotary recording and reproducing heads 21, 22 in a plurality of recording modes where FM image signals have different carrier frequencies. Previously recorded image information is erased by means of an erase head 23 prior to the recording operation. When the frequency of the erasure signal is set at about 10 MHz which is sufficiently higher than the carrier frequency, cross modulation distortion components do not come within a color signal bandwidth and thereby cross modulation distortion is eliminated from each recording mode.

Title: Propeller unit support structure for outboard engine
Inventor: KOBAYASHI HIDETAKA
IPC: F16F15/08
Filed: 1980-09-25
Abstract: PURPOSE: To effectively absorb vibrations of an outboard engine in the whole running conditions of the engine by providing the engine with a soft damping member and a hard damping member.  
     CONSTITUTION: During low load running of an engine, a propelling force is small, and hence a reaction force applied to a connecting means 36 is also small. Accordingly, deformation of a soft damping member 50 is also small so that vibrations of the engine are absorbed sufficiently by the soft damping member 50 and are hardly transmitted to a hull 22. On the other hand, during high load running, the propelling force is so great to deform the soft damping member 50 that an outer cylinder 56 is abutted against an end plate 72 or 74 which serves as a stop to further deform a hard damping member 48 or 52. Accordingly, during high load running, the connecting means 36 is equivalent to the hard damping member 48, 52 whereas during low load running, it is equivalent to the soft damping member 50.

Refractive indexes n1 to n3 of the first to the third dielectric layers satisfy relations: n1>n2, n3>n2 and by using Cu, Au, Ti and their alloys as the lower reflecting layer, reflectivity of an amorphous part can be raised and absorptivity of the amorphous part can be lowered to enable suppressing cross erasing.  Since there is no light absorbing layer on the substrate, thermal deformation of the substrate can be suppressed and repetitive characteristic can be improved.
