Title: Digital recording and reproducing device for hdtv signal
Inventor: OTAKA HIDEKI
IPC: H04N5/92
Filed: 1989-02-17
Abstract: PURPOSE:To suppress the deterioration of picture quality due to the restoration of a decoder as little as possible by setting up the detecting sensitivity of movement in a MUSE decoder to a low level. CONSTITUTION:Since a reproduced signal from a digital VTR is obtained by restoring a temporarily compressed signal, its picture quality is deteriorated as compared to the original MUSE signal and its SN ratio is also deteriorated, and at the time of detecting the movement of the signal, a noise component may be decided as movement in error and the picture quality may be furthermore deteriorated by misdecision due to the drop of movement detecting accuracy. If a still part is decided as a movement part in error, the resolution is deteriorated. In this device, a movement part detecting circuit 25 is controlled by a control circuit 20 to drop the sensitivity of movement detection. At the time of compressing and coding a MUSE signal and recording the coded signal, the deterioration of picture quality which may be generated when a decoder 17 restores the signal deteriorating its picture quality as compared to the original MUSE signal can be suppressed as little as possible.

Title: Non-resonance type knocking sensor
Inventor: KAWASHIRI SHOGO
IPC: G01H17/00
Filed: 1989-02-18
Abstract: PURPOSE:To correctly detect occurrence of knockings by forming non-polarizing parts at a part exhibiting itself at a connector part of a circular piezoelectric element and its opposite side. CONSTITUTION:A part (x) which exhibits itself at the side of a connector part 17 of a piezoelectric element 8 and a part (y) on the opposite side are formed with non-polarizing part alpha in advance. The non-polarizing part alpha formed on the part (x) is for preventing electric charge from occurring by oscillation transmitted from the connector part 17, while the non-polarizing part alpha formed on the part 9 is for preventing electric charge from occurring from the non- polarizing part alpha by wavy vibration transmitted from an engine. In this constitution, even if the vibration from the connector part 17 is transmitted to the element 8, there is no output occurred thereby preventing occurrence of noise signal due to vibration as well as preventing abnormal signal from being output even if unnecessary wavy vibration generated in the engine is transmitted to the element 8. Therefore output can be generated in response to only normal vertical vibration thereby allowing correct knocking to be detected.
