Title: Magnetic recording and reproducing device
Inventor: IWAI TOSHIO
IPC: G11B15/14
Filed: 1985-11-20
Abstract: PURPOSE:To suppress rainbow noise to be generated on an overlapped part of an ordinary VTR by erasing each track to be recorded by a preceding head in the same cylinder at the time of video recording. CONSTITUTION:Erasing current flows into a head scanning immediately before a head recording at present. For instance, when a head R1 23 starts recording, the erasing current flows into a head L2 22 preceding only by 1/3 a vertical scanning period T from the head R1 23. The timing for starting the flow of the erasing current into the head L2 22 precedes the timing for starting the flow of recording current into the head R1 23 by 1/3 vertical scanning period T. The end timing of the flow of the erasing current into the head L2 22 also precedes the end timing of the recording current by the period T. Since each track is erased by the head preceding the head being used at present by 1/3 vertical scanning period T, 1/3 previously recorded track is erased.

Filed: 1986-11-04
Abstract: PURPOSE:To improve the evenness in processing while accelerating the decomposition and removal speed by a method wherein a flow channel of O2 containing gas is formed of an inorganic material transmissive ultraviolet rays while discharging nozzles with slit type pores are used. CONSTITUTION:An organic material is irradiated with ultraviolet rays to be removed by means of forming a simple molecule such as CO2, H2O, O2, etc., reacting to optically decomposed compound or excited O. At this time, the ultraviolet rays in 184.9 nm or 253.7 nm play an important role in decomposing the organic material. When a gas flow channel is formed of a material transmissive ultraviolet rays in 184.9 nm or 253.7 nm producing O to irradiate gas with the ultraviolet rays, O2 is led into the processing chamber 11 while producing O3 and O in the flow channel. Furthermore, mixed gas containing O3 is irradiated with the same ultraviolet rays before the ultraviolet rays are through an ozone producer 16 to prevent the deterioration in concentration due to extinction of O3 from occuring while accelerating the production of O to be led into the processing chamber 11. Resultantly, the organic material in high concentration of O3 and O can be rapidly decomposed on the other hand, the slit type nozzles 15 at gas outlet play an important role in the evenness in the processing.

A road is not flat and has unevenness to rise and fall. When the abrasion (height reduction) of the bottom surface of the heel is considered, said angle alpha is set to 30 deg. or more if possible and, for example, 35 deg. is pref. Since the under surface 8 of the rear end of the shoe is notched and a space 10 is generated, the wt. is not supported only by the heel bone 2 and, therefore, the force shown by an arrow A is not generated and arthropathia is not deteriorated.
