Title: Production of carbon thin film
Inventor: MIYAMURA TAKESHI
IPC: G11B5/72
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To improve the bondability to a base material and to improve plastic strength by reacting a plasma and gaseous hydrocarbon under specific conditions. SOLUTION: At the time of forming a carbon thin film on the base material by an ECR plasma CVD process, the plasma and the gaseous hydrocarbon are reacted at a vacuum degree lower than 10<-1> Torr. The vacuum degree is adjusted by the supply rate of the gaseous hydrocarbon. Further, the plasma and the gaseous hydrocarbon are reacted under the conditions under which the partial pressure of the gaseous hydrocarbon attains >=99%. As a result, a deposition rate is exceedingly improved. The partial pressure is adjusted by the regulation of the flow rate and vacuum degree of the gaseous hydrocarbon. The carbon thin film obtd. in such a manner preferably has the plastic strength of >=20 mN. As a result, the good bondability is obtd. and the improvement effect of the durability is enhanced when the protective film of a magnetic recording medium is formed.  The thickness of the carbon thin film formed on a magnetic layer is set at about 5 to 20 nm.

Title: Manufacture of rare-earth magnet
Inventor: OSAWA ZENJIRO
IPC: H01F1/08
Filed: 1989-12-14
Abstract: PURPOSE:To manufacture a rare-earth magnet excellent in oxidation resistance by coating the surface of rare-earth magnet powder with a polymer mainly containing acrylonitrile. CONSTITUTION:A strong coating of a polymer mainly containing acrylonitrile with small oxygen permeability is formed on the surface of magnetic powder. The acrylonitrile polymer is strongly coupled with the rare-earth magnetic powder, especially neodymium magnet to suppress entrance of H2O and O2 as a nature of the polymer. A method for forming the coating of the acrylonitrile polymer may be such that a prepared polymer mainly containing acrylonitrile is solved in a solvent to be stirred with magnetic powder and then the solvent is eliminated or alternately such that single acrylonitrile or a mixture of acrylonitrile and another comonomer is surface-polymerized or graft- polymerized. Thus a good resin coating can be formed with simple processing and a rare-earth magnet excellent in oxidation resistance can be manufactured at a low cost.

Title: Formation of transparent conductive film
Inventor: MORIMOTO YOJI
IPC: H01B13/00
Filed: 1989-12-12
Abstract: PURPOSE:To shorten a necessary time for heat-treatment by putting a transparent conductive film in a treatment tank having a microwave transmissible window, making the inside of the treatment tank vacuum, and radiating microwave through the window. CONSTITUTION:Heat-treatment is carried out by radiating microwave through a microwave transmissible window 12 after a transparent conductive film 10 is put in a treatment tank 11 having the window 12 and the inside of the tank 11 is made vacuum. In order to lower resistance value, a transparent conductive film 2 to be heated is directly heated by microwave and since the microwave is transmitted through the transparent glass substrate 1 and the outer container 11A of the vacuum treatment tank 11, these parts unnecessary to be heated are not directly heated. Consequently, necessary time for increasing the temperature at start of heating and decreasing temperature at finish of heating can be shortened.

IPC: F01N13/00
Filed: 1989-12-15
Abstract: PURPOSE:To reduce pulsation noise or the like at the time of slow speed rotation and air noise or the like at the time of high speed rotation respectively by forming an exhaust discharging pipe into a double pipe structure and arranging an opening/ closing valve between the double pipes, while opening/closing the opening/closing valve in response to the rotation speed of an engine. CONSTITUTION:Exhaust air discharged from an engine passes through an exhaust admission pipe 14, a neck pipe 17 and an intermediate pipe 16, successively and flows into each of chambers E, F, D, successively so that exhaust noise is reduced by each action of expansion and resonance. In this state, at the time of low rotational of an engine, an electric actuator 21 is controlled by a control circuit 20 so as to close the valve body 18a of an opening/closing valve 18. It is thus possible to close the outside thick pipe 15a of an exhaust discharging pipe 15 which is composed in a double pipe structure so that the exhaust air is discharged after passed through an inside thin pipe 15b, while exhaust resistance is increased so as to decrease pulsation noise or the like. On the other hand, at the time of high rotational speed of the engine, the valve body 18a is opened, so that the exhaust air is discharged after passed through the whole of the double pipes 15a, 15b. It is thus possible to suppress the exhaust resistance so as to decrease air noise or the like.

Abstract: PURPOSE:To eliminate transmission line distortion by transmitting a luminance signal while split into a low frequency luminance signal (YL) including a band with the transmission line distortion in existence therein and a high definition luminance signal (YH), excluding the band of the signal YL subjected to distortion at the reception side, synthesizing the result with the signal YH and reproducing the synthesized signal. CONSTITUTION:A video signal obtained from a TV camera is subjected to pre-processing, converted into a luminance signal Y and inputted to the reception side. A signal with higher frequency than a frequency f0 lower than the upper limit transmission frequency of the standard system passes through an HPF and the high definition luminance signal YH is extracted. The signal YH is mixed 13 with a subcarrier fSH for high definition luminance signal from an oscillator 14 into carrier high definition luminance information YH', which is shifted into the transmission band of the standard system. The information signal YH' is added 12 with the signal Y and only the frequency in the TV transmission band is sent by an LPF 15. The signal YH is separated 21 from the signal sent at the reception side to obtain the information YH' and the signal YL is formed by subtraction, the result is given to an LPF 25 to obtain a frequency signal YL' lower than the frequency f0 is obtained. Moreover, the information YH' is subjected to frequency conversion by the signal fSH from an oscillator 24, given to an HPF to obtain the signal YH, which is added to the frequency YH'. Thus, the TV signal transmission system without any distortion is attained.

Abstract: PURPOSE:To attain the reception of a telephone call after a caller is confirmed by executing automatic hook on when a telephone call comes and a human body sensor senses the presence of a human body in the vicinity and sounding the voice of the caller from a speaker. CONSTITUTION:When a call comes to a telephone set 1 with a human body sensor 2 and a speaker 3 built therein and the sensor 2 senses the presence of a human body in the vicinity, the telephone set hooks on automatically and a caller voice is sounded from the speaker 3. When the called party leaves the state as it is by keeping the state for a prescribed time when the caller is a party not desired by the called party, and automatic answering message is sent automatically after a prescribed time elapses to release hook on. Moreover, when the sensor 2 does not sense a human body, no automatic hook-on is implemented. Thus, the telephone call is received after the opposite party is confirmed without talking up the handset at each arrival of call and the called party pretends to be not at home against a mischievous phone call.
