Title: Production of magnetic recording medium
Inventor: SHINOHARA GENICHI
IPC: G11B5/85
Filed: 1982-01-12
Abstract: PURPOSE:To increase the square ratio as well as the reluctance force, by using two evaporating sources and irradiating electron beams having the heating directions opposed to each other to these evaporating sources when a ferromagnetic layer is formed on a high polymer molded product substrate which moves along a rotary supporter. CONSTITUTION:A high polymer molded product substrate 1 of polyethylene telephthalate film, etc. is rewound out of a shaft 3 and then turned around a rotary supporter 2. Then two evaporating sources 7 (Co) and 8 (Cr) are set side by side, and electron beams 9 and 10 which are opposed to each other are irradiated to these sources 7 and 8. Thus these evaporating sources are heated, and a vertically magnetized ferromagnetic layer is formed on the substrate 1 via a mask 5 and under vacuum. Then a magnetic recording medium is taken up. In this case, it is also possible form an intra-surface magnetized layer by having different levels of energy for the beams 9 and 10. Thus the adhesion is improved to the substrate with a good square ratio and large reluctance force for a magnetic recording medium.

Title: Treatment agent of waste glutaraldehyde liquid and treatment of waste liquid using the agent
Inventor: NAGATA SATOSHI
IPC: C02F1/58
Filed: 1994-01-20
Abstract: PURPOSE:To lessen the adverse effects of a sterilizer/disinfectant glutaraldehyde upon microbes for drained water treatment when treating drained water using the sterilizer/disinfectant in medical care facilities. CONSTITUTION:A waste liquid treatment method inactivates residual glutaraldehyde by adding and mixing a treatment agent of waste glutaraldehyde liquid consisting of amino acid and/or alkali metal salts of amino acid with a waste glutaraldehyde liquid. This treatment agent of the waste liquid is easily soluble in an aqueous solution of a glutaraldehyde preparation, harmless and odorless, inactivates glutaraldehyde instantaneously, and prevents microbes for drained water treatment (activated sludge) from losing their activities. In addition, it is easy to determine whether the treatment is completed because the treatment agent becomes brown as the chemical reaction advances. Thus the treatment agent and the method using the agent are best suited for the treatment of a glutaraldehyde preparation in medical care facilities.

Abstract: PURPOSE:To eliminate the influence on the error at the time of an analog conversion by modulating a bit level digital signal by a first modem, transmitting the signal by plural codecs in digital and analog lines and demodulating the signal in a second modem. CONSTITUTION:A modem 2A modulates the outputs 0 and 1 of a randam code generator 1 to frequencies fa and fz. After this modulation signal is converted into a byte level digital signal in a codec 3A and a D/A conversion is performed for the signal in a codec 3B via a digital line 4A, an A/D conversion is performed for the signal in a codec 3C via an analog line 5 and a byte level digital signal 13 is outputted. A D/A conversion is performed for this signal in a codec 3D and the signal is demodulated in a modem 2B. Namely, because a digital signal 11 is modulated into frequencies fa and fz in the modem 2A and the signal is modulated into 0 and 1 again in the modem 2B by defining the signal as the object of the conversions of the codecs 3A to 3D, a bit error can be measured if this exists, even if the frequencies fa and fz levels corresponding to 1 and 0 change between signals 11 and 13.
