Inventor: HAYASHI YOSHIMASA
IPC: F01P11/18
Filed: 1984-09-29
Abstract: PURPOSE:To transmit alarm when the liquid level abnormally lowers by installing a temperature sensor at the part which is lower by a prescribed level from the liquid level in the cylinder head of an engine which executes evaporative cooling and generates heat when exposed from the liquid surface. CONSTITUTION:In the cylinder head 21 of an engine which executes evaporative cooling, the liquid level is controlled within the control amplitude as shown by the arrow in the figure around a set level l1 in the normal operation.

IPC: G11B5/62
Filed: 1981-12-16
Abstract: PURPOSE:To simplify working and to shorten the time of reduction, by producing a  signal and giving magnetism at one time to an information recording carrier which  contains a resin-coated layer cured by ultraviolet-ray containing magnetic fine powder. CONSTITUTION:A desired amount of the ultraviolet-ray curing resin mixed with the  magnetic fine powder is coated thin and evenly on the entire convex side of a base  material 1a by a roll coating, a spin coating or other coating processes. A material 1  is put with a coated layer 1b turned up is put on the upper surface of a die 3 of a press, and the pressure is applied to the material 1 while moving up the die 3 by a  hydraulic press. Thus contact between the layer 1b and a stamper 7 attached to a cope  5 of the press progresses while giving slight deformation of the material 1 gradually  toward the outside. As a result, air is pushed outside to eliminate the existence of air  bubbles between the layer 1b and the stamper 7. Under such conditions, the shutter 6  of an ultraviolet-ray source 10 provided at the lower part of the die 3 is opened to  irradiate the ultraviolet rays to the layer 1b. Thus the formation and hardening are  finished instantaneously. Then the hydraulic press 4 is opened to obtain an information  recording carrier in which the information signal is transcribed and formed to the  layer 1b containing the magnetic fine powder on the surface.
