Title: Video signal coding method
Inventor: YAGASAKI YOICHI
IPC: H04N19/134
Filed: 1989-10-14
Abstract: PURPOSE:To improve picture quality of transmission data by controlling a quantization step in response to a change in picture information to be sent. CONSTITUTION:Difference information representing a change between 1st picture information at a coded picture area RGS0 and 2nd picture information at adjacent coded picture areas RGSk adjacent to the RGS0 is obtained and the quantization step used for quantizing a digital video signal of the coded picture area RGS0 based on the difference information DIFF. For example, as to a picture part where picture information changes rapidly like an edge of an object, a small quantization step is used to execute delicate quantization processing.

Title: Ceramic percussion instrument
Inventor: SAKAI TSUNEZO
IPC: G10D13/08
Filed: 1988-10-25
Abstract: PURPOSE:To comparatively freely make a stable, clear, and deep sound from the title instrument and to industrially produce the instrument by forming a striking part using a ceramic material having a specific porosity. CONSTITUTION:The striking part is formed using the ceramic material having 0.1-50% porosity. Here, when the porosity is under 0.1%, the sound from the striking part becomes the one lacking in warmth like a sound from a metallic percussion instrument, and when the porosity is over 50% to the contrary, the sound from the striking part becomes the one having a short trailing note and unsatisfactory reverberations. Therefore, the porosity in both the above two cases is unsuitable. Further, when 20-50% porosity out of the above- mentioned 0.1-50% porosity range is adopted, it is specially preferable since the sound having beautiful reverberations peculiar to ceramics and an appropriate trailing note can be obtained. Thus, the stable, clear, and deep sound can be made comparatively freely, and the instrument can be produced industrially.

Abstract: PURPOSE:To eliminate inductive faults at electric energization times and to reduce the equipment cost by installing a direct electric current source as an energization source and energizing a stock to be heated by a direct current. CONSTITUTION:An electric source 6 supplies a prescribed direct electric current to every electrode member of a movable carriage of a heating device 3, receives three-phase alternating currents as an input, and rectifies them to output a direct current.

Therefore, countermeasures against the interference for peripheral devices are eliminated; the power-factor is well balanced and is able to be about 100%, and an electric power is effectively used because three- phase currents are adopted as the input electric source. Thus, the energy charge is reduced, the countermeasures for peripheral devices are eliminated to reduce the equipment cost.
