Title: Floating type magnetic head
Inventor: YAMAMOTO FUMIO
IPC: G11B5/60
Filed: 1978-02-03
Abstract: PURPOSE:To obviate entry of contaminations to the floating face of flat part by dispersing and disposing sliders in the direction at a right angle to the travel direction of recording medium surface. CONSTITUTION:With the front floating faces 112, 122, the tapered floating faces 113, 123 create an increase in pressure P from their front end position and a maximum pressure peak P3 is generated near the boundaries 115, 125 of the taper part and flat part. The sharp pressure decrease after the maximum pressure peak lets dewing by adiabatic expansion to be caused. This dewed moisture absorbs the oil vapors, etc. in the atmosphere and becomes liquid drops which will then deposit on the front floating faces 112, 122. Here, the front floating faces 112, 122 and rear floating faces 111, 121 are not on the same track and therefore the liquid drops collect on the front floating faces of a relatively large clearance from the magnetic disc or collect at the trailing end behind these and are discharged from the trailing end without flowing to the rear floating faces.

Filed: 1990-01-23
Abstract: PURPOSE:To conduct, without fail, shutting down of a nuclear reactor and suppression of its output in case of an accident, without requiring any outside operating force, by equipping the first storage vessel and the second storage vessel into which a liquid neutron absorber is placed and an inert gas sealed in. CONSTITUTION:A case where a reactor core cooling is disabled during operation of a nuclear reactor, resulting from a certain cause such as a failure of a circulation pump and the like, is presumed. In such a case, a coolant pressure decreases and inner gas of a lower chamber 36, the first storage vessel 33 and the second storage vessel 34, expand. As a result, almost all of a neutron absorber 41 is forcedly flowed into the first storage vessel 33. At this moment, a liquid surface 40 of the coolant in a pipe body 37 is substantially lowered from the level during a normal operation. In this way, a large amount of the neutron absorber is automatically sent into a reactor core 15 region, by pressure drop in case of an accident of the nuclear reactor and therewith reactor shutting down or suppression of the reactor output can be attained.
