Title: Aluminum alloy substrate for magnetic disk
Inventor: NIITSUMA AKIRA
IPC: G11B5/82
Filed: 1989-11-16
Abstract: PURPOSE:To harden an aluminum substrate itself by adding alloy elements of the aluminum alloy to have concentrations above the limit of solid solution and then precipitating or crystallizing a very hard second phase in a dense and uniform state. CONSTITUTION:The aluminum alloy substrate is formed in a manner that the surface has uniform distribution of one or more alloys of Al-Cu, Al-Mg, and Al-Cu-Mg in the second phase with the area proportion of >25% for Al-Cu, >13.5% for Al-Mg and >21% for Al-Cu-Mg, and that the surface has >150kg/mm<2> microvickers' hardness. As for the Al-Cu alloy, enough hardness can not be expected if the Cu proportion is <20%, while with over 45% Cu, the alloy becomes undesirable because of bad cutting workability and increase in weight. As for the Al-Mg alloy, enough hardness can not be expected if the Mg proportion is <11%, while with over 40% Mg, oxidation of active Mg can not be prevented and the alloy becomes brittle. As for the Al-Cu-Mg alloy, 5 - 45% of Cu and 8 - 40% of Mg is preferable. Thus, the aluminum substrate can be hardened.

Title: Fault detection circuit of operational amplifier
Inventor: HASHIMOTO TETSUAKI
IPC: G01R31/00
Filed: 1993-11-29
Abstract: PURPOSE:To detect a fault surely and at a high speed by installing a fault detection circuit using a window comparator at output terminals of one or more of a plurality of operational amplifiers which have been connected in series. CONSTITUTION:When operational amplifiers 11, 12 are normal, the output of the amplifier 11 at nearly zero volt. The fault detection circuit 5 is constituted of two analog comparators whose comparison voltage level is respectively different. When an input voltage exceeds the range of two comparison voltages, the circuit is operated and generates a detection output. That is to say, a so- called window comparator is constituted. The detection range is around nearly zero volt, but it is set to be a little wider than a voltage range which is output normally by the amplifier 11. Consequently, when the amplifier 11 causes a fault, the output of the amplifier 11 is deviated largely from a value near zero volt, the circuit 5 is operated, and the fault of the amplifiers 11, 12 can be detected quickly.

Filed: 1992-10-12
Abstract: PURPOSE:To secure the time required for completion of preparations for transmission of the next page. CONSTITUTION:Protocol procedures to play for time at the time of abnormality are set in a setting part 23. When detecting that a document of the next page is not prepared because of an abnormality of supply or the like, a next page preparation detecting part 18 outputs the detection signal to a switching control part 17 and controls it to close a switching part 16. As the result, protocol procedures in the setting part 23 are used instead of protocol procedures in a procedure setting part 22 to control a communication control part 15. Procedures which send EOM to forcibly execute the procedures of a phase B, procedures which send a host message command MPS again in the case of incompletion of preparations of the next page after MCF reception, or the like are set as procedures to play for time.

Title: Combustor
Inventor: NAKATANI KAZUTO
IPC: F23D3/10
Filed: 1987-11-26
Abstract: PURPOSE:To prevent the deterioration of waste gas characteristics, improve combustion characteristics and widen an adjustable range of combustion by providing a flow control cylinder having a nearly covered bottom within an inner flame cylinder and disposing a second throttle part above a first throttle part of an outer cylinder. CONSTITUTION:As the height of the exposed part of a wick 1 is decreased so as to reduce a combustion rate, the flame becomes gradually smaller in the combustion chamber 8, and the amount of unburnt fuel gas flowing into control zones 25a, 25b, 25c is also reduced. The unburnt fuel gas is obstructed to flow above the flame FL by the air supplied from an air hole 27 and an air passage 29. Because of the obstruction effect, the air emitted from air holes 11 and an opening 13 in the inner flame cylinder above the flame is clean. The unburnt fuel gas flowing into a circulation zone 20 is also introduced into a combustion chamber 8 by a second throttle part 19, and almost of the gas is burnt with the flame FL. Therefore, little unburnt gas flows through an air passage 23, and the air discharged from through-holes 16 of the outer flame cylinder 7 is relatively clean.

Abstract: PROBLEM TO BE SOLVED: To provide an operating pedal, which hardly slips even when a sole is made with water by rain or the like, by composing the anti-skid operating pedal of a porous anti-skid member, which is hard and has water permeability, formed by sintering powder. SOLUTION: An anti-skid member 3 has water permeability for absorbing moisture on a wet sole 5, on its surface, ruggedness is formed so as to hardly slip it even in the case of contact with the sole 5, and the powder is sintered. This sintered anti-skid member 3 is fixed with a pedal 1 by screwing or adhesive agent. In such a case, since an irregular surface formed from powder exists on the surface of the anti-skid member 3, a friction coefficient is high, and this surface plays the role for satisfactorily preventing skid to the contact with the sole 5. Therefore, concerning this anti-skid member 3, its surface is made coarse, an anti-skid effect can be expected with that surface itself and further, prescribed water permeability or absorbing performance can be presented by internally forming a lot of holes mutually through the member.
