Abstract: PURPOSE:To record and reproduce high-quality pictures, by providing a pump- out spiral groove on one face of end faces facing each other of cylinders. CONSTITUTION:A pump-out spiral groove 18 is provided on the lower end face of an upper rotary cylinder 2, and a spiral groove 22 whose groove part is continuous from the upper end to the lower end of a cylinder face is provided on the outside circumferential face of the rotary cylinder 2. When the upper rotary cylinder is rotated, the air inside a rotary head assembly is discharged to the outside by the dynamic effect of air in the narrow space formed between the upper end face of a lower fixed cylinder 3 and the lower end face of the upper rotary cylinder 2. Meanwhile, the spiral groove 18 of the upper rotary cylinder 2 generates the air current going downward from the upper end part of a tape 1 by the dynamic action of air in the narrow space formed between the surface of the magnetic tape and the outside circumferential face of the upper rotary cylinder 2 when the magnetic tape is wound around the rotary head and runs.

Title: Vapor cooling device
Inventor: MATSUMOTO MASAICHI
IPC: H01L23/427
Filed: 1983-06-27
Abstract: PURPOSE:To produce a vapor cooling device with excellent cooling capacity by a method wherein an automatic resetting gas releasing device is provided near topmost position of sealed vapor phase part. CONSTITUTION:The releasing and resetting pressure of an automatic resetting gas releasing device 14 is set up to specified value and when a heating element 1 is heated, the air mixed with the gas in a vapor phase part and the air resolved in a liquid phase part are released to be stagnated in the upper part of a sealed vessel 2 and a condenser 5 deteriorating the cooling capacity thereof with the vapor phase content of cooling medium 3 insufficiently condensed raising the internal pressure of the sealed system. When the internal pressure exceeds the specified value, the device 14 is automatically opened to externally release the air in the upper part of the vapor phase part. When the condenser 5 recovers the specified cooling capacity thereof after releasing, the internal pressure declines to reset said device 14 to closed position. During these operations, the internal air shall not be mixed with atmospheric air at all and even if mixed with the same due to any seal leakage, it will be released from the device 14 by said operations when the heating element 1 is heated to maintain normal operations without deteriorating the cooling capacity.

Title: Intermediate heat exchanger
Inventor: YAMAZAKI SEIJIROU
IPC: F28D7/00
Filed: 1980-08-28
Abstract: PURPOSE: To prevent a by-pass flow of a primary coolant with a simple construction or arrangement by a method wherein a spherical surface seat is arranged at a part of the inner cylinder of an intermediate heat exchanger, a conical surface seat is arranged at an outer cylinder, and the seats in both cylinders are contacted with each other.  
     CONSTITUTION: The primary coolant flowed from an inlet nozzle 2 is reached to a clearance passage between the outer cylinder 7 and the inner cylinder 10 and divided into ascending flow and descending flow. The primary coolant which is apt to flow downwardly is prevented from its flowing due to the fact that the conical surface seat 6 arranged at the outer cylinder 7 is contacted with the spherical surface seat 14 arranged at the inner cylinder 10, thereby the coolant may not flow below lower than the contacted seats. Due to this arrangement, almost of all the primary coolant is ascended in the clearance passage between the outer and inner cylinders, passed through the primary coolant inlet port 12 and heat exchanged with the secondary coolant flowed in a heat conductive pipe 9, resulting in preventing any thermal loss therein.
