Patent JP-S63197896-A (JP)
Title: Heat exchanger
Inventor: USUI YOSHIYUKI
IPC: F28F27/00
Filed: 1987-02-12
Abstract: PURPOSE:To make a stable temperature of heated item in a short period of time when a power supply is turned on after its off-state by a method wherein a temperature sensing means is arranged near a secondary cooled item of a heat exchanging unit and means for controlling a flow rate of a secondary cooling medium in accordance with sensed temperature is provided. CONSTITUTION:When a temperature sensor 6 detects that the temperature of secondary cooling water T2 is varied, the result is fed back to a temperature adjustor 9b. The temperature adjustor 9b may control the number of revolution of a pump 7 to enable secondary flow rate l2 to be varied and then control it in such a way as temperature T2 of the secondary cooling water is kept constant. With this arrangement, when the temperature T2 is high, the flow rate l2 is increased, and in turn when the temperature T2 is low, the flow rate l2 is decreased; thereby, it is possible to keep it at a constant temperature. Since an object can be accomplished only with a controlling of a small flow rate, the cooled item 3 can be stabilized in a short period of time after the power supply is turned on again to a normal temperature.

IPC: G11B11/10
Filed: 1991-01-31
Abstract: PURPOSE:To record ternary data on a magneto-optical recording medium constituted of a material composed of rare-earth elements and transition metals. CONSTITUTION:An S- or N-magnetic field or no magnetic field is formed around a magneto-optical disk 50 of a material composed of rare-earth elements and transition metals by using a magnetic head 12.
