Title: Production of magnetic recording medium
Inventor: SUGITA RIYUUJI
IPC: G11B5/85
Filed: 1980-04-14
Abstract: PURPOSE:To produce a magnetic recording medium of superior short wavelength recording characteristics by using an electron beam as a evaporating source and maintaining a substrate at positive potential with respect to the evaporating source in forming a Co-Cr magnetic film on the substrate by a vacuum deposition method. CONSTITUTION:A medium substrate 2 consisting of a high-polymer material is disposed above a vacuum vessel 13, and a evaporating source 17 consisting of a water- cooled copper hearth 19 in which a thin-film material 18 is housed is disposed therein. Thence, an electron beam 21 is generated from an electron gun 20 provided near the evaporating source 17 to heat the thin film material 18, and positive potential with respect to the evaporating source 17 is impressed from a DC power source 22 to the substrate 2, so that the magnetic layer consisting essentially of Co and Cr is formed on the substrate 2. Thereby, the vertically magnetized film consisting essentially of Co and Cr is formed on the high-polymer substrate of poor heat resistance without giving any damage thereto.

CONSTITUTION:A dividable female mold 3 having a swollen out part 1 on the circumference is manufactured, a pressurizing hole 5 is provided in one direction of the mold 3, and a relief hole 9 is provided on the central part of an end face 7 of the opposite side of the same. In the composite raw materials 11, reinforcing long-sized fibers 13 are arranged unidirectionally, and the composite raw materials 11 are placed within the mold 3 so that the direction of the fibers are coincident with that of the pressurizing hole 5 and relief hole 9. Compression force is applied to the composite raw materials 11 in the direction of the fiber by a punch 17 through the pressurizing hole 5. Although the inside of the mold 3 is filled with the composite raw materials 11 and a molded product in a predetermined form is obtained through the compression force, the long-sized fibers 13 is stretched out up to the inside of the relief hole 9 by running along a form of the swollen out part 1 due to existence of the relief hole 9. Simultaneously with the above, the long-sized fibers 13 pass straight through extending over a molded product without bending in the central part of the molded product and a high-strength molded product can be manufactured.

Filed: 1979-04-24
Abstract: PURPOSE: To enable the early and sure detection of hydrogen gas leakage, by connecting a vacuum gas separation vessel and a hydrogen gas detector to the return pipe of a rotary machine.  
     CONSTITUTION: A prescribed quantity of pure water is always conducted from the return pipe 8 of a rotary machine to a branch pipe 9 and sprayed in a separation vessel 11. The separation vessel 11 is maintained in a vacuum state by a vacuum pump 12 so that air and gases dissolved in the pure water can be easily separated from the water. Therefore, hydrogen gas dissolved in the pure water is separated therefrom in the separation vessel 11. When the separated hydrogen gas is released into the atmosphere through the vacuum pump, the gas is detected by a hydrogen gas detector 13 and a relay 14 acts to cause an alarm 15 to give warning. The hydrogen gas dissolved in the pure water can be surely detected even if the quantity of the hydrogen gas is minute.

Title: Elastic synchronizing system continuous vibration-proof device in foil manufacturing apparatus
Inventor: YOKOYAMA TAKAO
IPC: B21J7/20
Filed: 1982-03-31
Abstract: PURPOSE:To obtain a vibration proof effect in a state that the whole machine is installed to the foundation without supporting it elastically, by executing impulsive transfer force generated by a hammer system foil manufacturing machine, by jointly using buffer and interference. CONSTITUTION:Two groups of a hammer 1 connected to a crank slider mechanism 5 through a spring 4, and an anvil 2 supported by an air spring 3 are provided back to back with each other on a machine body 6. When phase of cranks of the mechanisms 5, 5 is shifted by 180 deg. with each other, and the hammer is excited by rotating one driving shaft 7 by a driving device 8, the moving forms of the hammer and the anvil of each group are same but are shifted from each other by a half period each. Impulsive transfer force from the anvil system is buffered once by the spring 3. On the other hand, as for transfer force from the hammer and anvil systems, since its period coincides with the exciting period, therefore, as for the whole transfer force, each transfer force from both the systems, which is shifted from each other by a half period is synthesized, a fundamental vibration component is raised, and higher vibration components of odd order interfere with each other and are cancelled. As a result, only components of even order are left, but by control of air pressure of the spring 3, collision at the still position of the anvil becomes possible.

IPC: F24F6/10
Filed: 1989-03-03
Abstract: PURPOSE:To control the humidity in the internal space by attaching a heat generator to or embedding same in the front and rear sides of a moisture absorber which has pores in it and carries the mixture absorbing filler in the pores of the porous object that interrupts the air flow. CONSTITUTION:A heat generator 2 and a heat generator 3 are attached to or embedded in the front and rear sides of a moisture absorber 1 to form a humidity controlling base material A. The moisture absorber 1 has continuous pores and carries a moisture absorbing filler in the pores of the porous object that interrupts the air flow. The humidity controlling base material A is installed so as to separate the internal space of a storage compartment 9 from outside. When the humidity in the compartment becomes higher than the set level, the outside heat generator 2 is caused to generate heat to reduce the humidity in the compartment, and, when the humidity in the compartment becomes too low, the inside heat generator 3 is caused to generate heat to release the humidity back into the compartment. The humidity in the compartment can thus be maintained in a certain range.

Abstract: PURPOSE:To make it possible to muffle an exhaust sound by regulating the opening of a suction passage for the control of an exhaust amount of suction air from a combustion chamber, thereby controlling a suction air supply to the said chamber and discharging a part of the suction air to the upstream side of a silencer in an exhaust air passage. CONSTITUTION:In a suction stroke where a suction valve 7 opens and a piston 3 comes down, suction air is fed to a combustion chamber 4 through a suction passage 5, and the volume of the air so fed is detected by a primary air flow sensor 9. On the other hand, when the piston 3 passes the bottom dead center and moves for a compression stroke with the suction valve 7 closed, a part of suction air is discharged into a suction exhaust passage 14. At this stage, a control valve 16 controls the opening and closing of the said passage 14 and the exhaust volume of suction air. Also, the exhaust volume of the suction air is detected by a secondary air flow sensor 18 and the value so detected is deducted from that available from the primary air flow sensor 9 for calculating the necessary supply of air to the combustion chamber 4. Thereafter, the suction air is introduced to the upstream side of a silencer 11 in the exhaust passage 6.
