Title: Production of magnetic recording medium
Inventor: AWANO HARUO
IPC: G11B5/85
Filed: 1984-11-30
Abstract: PURPOSE:To improve durability with good controllability without an increase in film thickness and spacing loss by forming a magnetic layer consisting of a thin ferromagnetic metallic film on a non-magnetic substrate and irradiating a neutral particle beam on the magnetic layer. CONSTITUTION:Any magnetic recording medium constituted by depositing directly a ferromagnetic metallic material on the non-magnetic substrate and forming a thin metallic film as the magnetic layer on said material is acceptable as the magnetic recording medium. Said medium is therefore applicable to, for example, a magnetic recording medium for vertical magnetic recording or so-called a thin ferromagnetic metallic film type magnetic recording medium, etc. The magnetic layer of such magnetic recording medium is subjected to a surface treatment by irradiating the neutral particle beam thereon by using a neutral particle beam gun to bring the neutral particles into collision against the surface of the magnetic layer, thereby injecting the neutral particles onto the magnetic layer. In actual treatment, a base film 5 formed thereon with the magnetic layer 4 is disposed in a vacuum chamber 1 in such a manner that the layer 4 and a neutral particle beam generator 3 face each other. The oxygen neutral particle beam generated from the generator 3 is irradiated on the layer 4, by which the surface of the layer 4 is treated.

Title: Thermal conveyor
Inventor: JAKUDO JUNICHI
IPC: F24D7/00
Filed: 1986-10-24
Abstract: PURPOSE:To increase thermal conveyance capacity by smoothly performing reflux from a liquid reservoir tank to a generator, by connecting the upper part of a generator to the upper part of a liquid reservoir tank with a connecting pipe in which an on-off valve is provided and through which steam dynamic pressure produced by the generator is applied. CONSTITUTION:An operating liquid 16 is boiled and vaporized to increase the pressure in a generator when it is heated by the generator 1. The steam of an operating liquid 16 is fed into a heat exchanger 13, where it radiates heat, condensed and liquified, and is fed into a liquid reservoir tank 3 to raise the liquid level of an operating liquid 16. When an on-off valve 7 is pushed upward by the buoyant force of a float 2, the pressure of the generator 1 is introduced into the liquid reservoir tank 3 from a steam inlet port 5 through a connecting pipe 8, and the operating liquid 16 in the liquid reservoir tank 3 is returned to the generator 1 by the force of gravity produced by the difference between the liquid level of the operating liquid 16 in the generator 1 and that in the liquid reservoir tank 3. The connecting pipe introduces the overall pressure of steam of operating liquid 16 produced by the generator 1 into the steam inlet port 5, so that the overall pressure of steam is always introduced into the steam inlet port 5 even if the dynamic pressure constituent of steam is increased by the increase of thermal conveyance volume. The difference between the liquid level of operating liquid 16 in the generator 1 and that in the liquid reservoir tank 3 can be utilized effectively, and reflux of the operating liquid 16 is taken place smoothly.

Abstract: PURPOSE:To discern a variety of test specimens in accordance with the actual condition by discerning the test specimens to be good if the leaking component is not larger than a permissible value even when it is not zero. CONSTITUTION:A pseudo leak test of a reference container which is already known to have no leak is performed, thereby to detect the pressure change  Pr does not include leaking components, error components Eo can be obtained based on the pressure change  Pr. Immediately after the error components Eo are detected, namely, before the error components are changed, a leak test for a test specimen is carried out to detect the pressure change  Ps. The average value Ao of the leaking components of the good test specimen is obtained on the basis of the pressure change  Ps and error components Eo. Subsequently, a leak test for many test specimens is sequentially carried out. At this time, the leaking components Ai are obtained b an equation Ai= Pi- Pav+Ao wherein Pav is the virtual average value of the pressure change of the good test specimens tested before the specimens being tested.

Title: Semiconductor output circuit
Inventor: MIYASHITA TAKUMI
IPC: H03K19/0175
Filed: 1988-10-07
Abstract: PURPOSE:To suppress the fluctuation noise of a GND voltage which occurs when an output signal falls by negative-feeding back the output signal of a driving circuit to the MOS transistor of a logical circuit. CONSTITUTION:An MOS capacitance TNC bypasses a space between the gate G and the drain D of the NMOS transistor TN5 in such a way that the ON- operation of the NMOS transistor TN5 for permitting the output signal of an output pad 103 to fall is prevented, and delays the potential of the gate G, whereby a negative feedback circuit which applies negative feedback by such a potential is constituted. Since a fall speed is set to be gentle by the operation of the MOS capacitance TNC at the time of fall, a discharge current id is prevented from falling as steep as a rush current, and the fluctuation of the GND voltage VEE can be suppressed.
