Title: Muse receiver with built-in waveform equalizer
Inventor: YAMASHITA AKIHIKO
IPC: H04N7/015
Filed: 1989-06-07
Abstract: PURPOSE:To prevent malfunction of a waveform equalizer by stopping fetch of a VIT pulse data at the generation of dropout of an input MUSE signal. CONSTITUTION:The generation of dropout for a fetch period of a VIT pulse is detected by a VIT pulse defect detection circuit 50 and it is regarded that a fetch data of a VIT pulse is incomplete, and a switch 45 being a stop means is thrown to the position of a storage circuit 44. Thus, an arithmetic mean circuit 40 applies arithmetic mean processing according to the fetch data of the VIT pulse in the preceding frame without defect. Thus, since the switch 46 stops fetching the input VIT pulse at the occurrence of dropout, malfunction of an equalizer is avoided.

Title: Method for surface-hardening shaft sliding part having groove by laser
Inventor: ITO SHUJI
IPC: C21D1/09
Filed: 1988-06-14
Abstract: PURPOSE:To harden a shaft sliding part having a groove into martensitic structure by rapid self cooling and to stabilize the hardness of the part by using a laser beam in the hardening of the part. CONSTITUTION:An absorbent is uniformly applied on the shaft sliding part 3 having a groove 5, and then a work 1 is rotated by a positioner. The part 2 of the sliding part 3 to be hardened is irradiated by a rectangular laser beam 4. As a result, the part 2 is rapidly heated to a temp. higher than the austenitizing temp., and then irradiation by the laser beam 4 is stopped. Since the work 1 is rotated, only the surface layer part is converted into hard martensitic structure by rapid self cooling and hardened. As an annealed region is formed only in the groove 5 and not formed on the sliding surface 6 by this hardening, the wear resistance is hardly deteriorated.
