Title: System for controlling searching operation of magnetic recording and reproducing device
Inventor: SUI MASAHIRO
IPC: H04N5/783
Filed: 1984-05-31
Abstract: PURPOSE:To apparently reduce the omission of information, by controlling the transferring speed of a recording medium so that the pattern of a recording track observed from the existing position of a rotary head can become a prescribed one and setting the position of one out of noise bars to a position which does not appear in a reproduced picture. CONSTITUTION:If a tape speed becomes nine times faster than that at the time of normal reproducing mode in a search reproducing mode, the pattern of a recording track observed from the existing position of a rotary head to a head switching signal SWP as shown in Fig. (A) becomes the one shown in Fig. (C). At this time, the signal level of a reproduced RF signal becomes the one shown in Fig. (B) and information of four recording tracks only is obtained on one-field period by the azimuth effect of the magnetic head. When the frequency outputted form a four-frequency signal generating circuit 8 is made coincident to the frequency of a pilot signal recorded on the track corresponding to the 3rd information as shown in Fig. (D) under this condition, a tracking error signal becomes ''0''V at the point where the RF signal containing the 3rd information becomes the maximum as shown in Fig. (E). Therefore, the generating timing of a sampling pulse (a) is made coincident to the point where the RF signal containing the 3rd information becomes the maximum as shown in Fig. (F).

Title: Heat conductive surface for condensation

IPC: F28F13/00
Filed: 1978-09-14
Abstract: PURPOSE: To reduce a thickness of a liquid film as much as possible and obtain a heat conductive surface for condensation having big heat conductivity by arranging members having a copillery action on the heat conductive surface of a wall at a proper distance.  
     CONSTITUTION: Members 3 having capillery action are arranged at a proper distance on a surface of a wall kept in low temperature. When steam of high temperature is blown against the wall 1, the steam is condensed into liquid 2 and most of the liquid 2 is absorbed by the capillery action of the capillery members 3 upon dropping. Therefore, a film of the liquid 2 on the surface 1 of the wall becomes very thin. Contacting surface between the steam and the capillery members 3 is wide enough because of the porosity of the members 3, therefore, actual heat conducting area becomes wide and separation of the liquid from the wall is improved, thereby, heat conductivity due to the condensing way be improved remarkably. Metallic screen, felt, sintered metals or the like is utilized as the material of the capillery member 3.
