Title: Heat conductive material for vapor cooling
Inventor: NAKAJIMA TADAKATSU
IPC: H01L23/44
Filed: 1987-02-04
Abstract: PURPOSE:To stably cool a heat generating body having high heat generating density by eliminating stable existence of film boiling which interferes with heat conduction through formation of many protrusions at the external surface of heat conductive material having many opened through holes. CONSTITUTION:Many protrusions 24 are formed to the external surface of a heat conductive material 20 having many opened through holes 26, 27 at the external surface thereof. Therefore, when the heat is applied to the heat conductive material 20 with the heat conductive flux higher than that for starting the boiling from the heat generating body, vaporization and boiling of coolant are generated at the internal surface and external surface of through holes 26, 27 of the heat conductive material 20 and the heat generating body is cooled by latent heat of vaporization through the heat conductive material. With increase of heat applied to the heat conductive material 20, bubbles generated from the surface of heat conductive material also increases. Finally boiling of core changes to film boiling and the surface of heat a conductive material is covered with vapor film. This vapor film, however, is broken by geometrical shaping effect of protrusions at the surface of heat conductive material and conduction of core boiling is attained. Thereby, the heat generating body with high heat generating density is stably cooled.

Abstract: PURPOSE:To effectively shield leaking of light from a fixing processing part. CONSTITUTION:A shutter 546 is arranged inside a cover 530 in the vicinity of a notch 536. The shutter 546 is hung by a shielding plate rotating shaft 548 and is made to be freely rotatable. A guide roll 550 which is made to be freely rotatable, is provided on a surface on a side of a developing part 38 of the shutter 546. When a direct printing plate 14 is placed on a mounting plate 522 and carried, the guide roll 550 is abutted or an edge part on a leading side in the carrying direction of the direct printing plate 14 and the direct printing plate 14 is proceeded inside the fixing part 44 by rotating the shutter 546. Because the guide roll 550 is made to follow over the direct printing plate 14, the space between a bottom edge part 546AB of the shutter 546 and the direct printing plate 14 is made approximately fixed. Thus, the space between the shutter 546 and the direct printing plate 14 can be made extremely narrow and the leaking of light to a developing part can be reduced.

Title: Reproducing device for control signal
Inventor: SATOU TSUGUO
IPC: G11B15/52
Filed: 1981-02-23
Abstract: PURPOSE:To obtain always a stable control signal, by detecting a peak value of a reproducing control signal and using its voltage as a DC shift voltage to control the setting of a comparison level. CONSTITUTION:A peak-to-peak value of the reproducing control signal from a magnetic tape 1 is detected by a peak detector 4, and a DC voltage corresponding to the peak-to-peak value of the reproducing control signal is generated through a differential amplifier 5 and becomes a DC shift voltage. This shift voltage is superposed onto the reproducing control signal by an adder 6 and is processed in a comparing circuit 7, where a reference voltage is set, to generate a servo control signal. By this system where the setting of a comparison level is controlled by the DC shift voltage corresponding to the peak value of the reproducing control signal, the servo control signal corresponding only to a correct reproducing control signal is generated even if the control signal has a level difference and noise or the like is mixed, and thus, a reproducing device where malfunctions are prevented is obtained.
