Title: Disc plate for disc brake and its manufacture
Inventor: KOTANINO SADAYUKI
IPC: B21D53/34
Filed: 1981-06-06
Abstract: PURPOSE:To radiate friction heat of a plate at brake operation and improve its cooling performance, by effectively utilizing negative pressure. CONSTITUTION:As a disc plate 1 is turned to the direction of an arrow head r, interposed air in a gap S flows out to the direction of an arrow head f by centrifugal force, and inflowing air f0 from a side of the center of the disc plate 1 flows into reverse sides 3 and 8 of a friction pad sliding surface to cool a pad. If a rotary speed of the disc plate 1 is further increased, negative pressure is generated in a window part 4, and interposed air in this portion is sucked as shown by an arrow head f1 in FIG. 9 and released to the direction of the arrow head f by centrifugal force, then brake friction heat, between the main disc plate 1 and annular disc plate 7, can be positively scattered to the atmosphere to prevent the fade phenomenon.

Abstract: PURPOSE:To produce a coating film having high hardness, superior wear and corrosion resistances by forming a porous ceramic coating film on the surface of a metal with SiO2 particles having a specified background intensity as a base, impregnating and calcining a soluble Cr compd. and repeating these stages. CONSTITUTION:SiO2 as starting material is crushed in a relatively short time so as to inhibit the formation of superfine particles of about <=100nm particle size. The resulting particles are classified, coarse particles are removed and SiO2 particles of about <=3mum average particle size are obtd. The background intensity of the obtd. SiO2 particles in the range of 20-30 deg. angle 2theta of diffraction in X-ray diffraction is <=1/10 of the peak height of diffraction of the (100) face of SiO2 at about 21 deg. angle 2theta. A slurry contg. ceramic particles based on about 80% of the SiO2 particles and further contg. Cr2O3, etc., is applied to the surface of a metal, dried and calcined to form a porous ceramic coating film of about 10-120mum thickness. A soluble Cr compd. is impregnated into the coating film and calcined at 400-600 deg.C and these stages are repeated to obtain a corrosion and wear resistant coating film having about 1,600-2,000 Vickers hardness Hv.

Title: Jointing part for structural steel member
Inventor: NARIHARA HIROYUKI
IPC: C21D9/50
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To improve strength for a structural steel member by a method wherein a range in a specified length extending from the jointing end of a beam to its center at a structural steel column-beam jointing part is highly strenghtened by heat treatment such as high frequency inductive heating or the like. SOLUTION: A range in a specified length extending from the jointing end of a beam 2 to its center at a structure steel column-beam jointing part A is highly strengthened by heat treatment. Or, a range in a specified length extending from a horizontal stiffener to the center of the column positioned at an extension line of the beam 2 may be highly strenghtened by heat treatment. High frequency inductive heating is desirable to be used as a method for the heat treatment. With such treatment, a plastic deformation part F becomes a part separating at a specified distance from the heat-treated part E, and when stress concentration occurs at this part, the sectional shape of the member becomes constant with sufficient toughness and can be prevented from resulting in breakage with external force dampened even though plasticization occurs partly.  Therefore, strength can be improved for the structural steel members.

Abstract: PROBLEM TO BE SOLVED: To reduce noise satisfactorily in a low rotational region of an internal combustion engine, and simultaneously maintain output in its high rotational reason. SOLUTION: When an internal combustion engine is in a low rotational region, a flange 9 contacts with a valve seat 5 because energization force of a spring 7 overcomes exhaust gas pressure which the flange 9 receives, an outside exhaust gas path 13 which is formed from the outer peripheral face of a cylindrical part 8 and the inner peripheral face of a pipe 2 is shielded by the flange 9, and only inside exhaust gas path 14 which is formed from the inner peripheral face of the cylindrical part 8 is opened. When the internal combustion engine is in a high rotational region, the flange 9 is separated from the valve seat 5 because exhaust gas pressure which the flange 9 receives overcomes energization force of the spring 7, and the outside exhaust gas path 13 and the inside exhaust gas path 14 are both opened.

Title: Adaptive pi control system
IPC: G05B13/02
Filed: 1992-03-13
Abstract: PURPOSE:To provided the adaptive PI control system which is very robust even against the variance of inertia, dynamical friction coefficient, or the like. CONSTITUTION:A speed deviation EPSILON<(1)>(=thetar<(1)>-theta<(1)> is added to the value obtained by multiplying a position deviation EPSILON(thetar-theta) between the command position and the motor position by a position loop gain Kp to obtain a phase surface Suf. The value obtained by multiplying the value of this phase surface Suf by a constant K2, the value obtained by multiplying the integral value of the phase surface Suf by constant 1/gamma, the value obtained by multiplying a command acceleration thetar(2) by an estimate value Jhat of inertia, the value obtained by multiplying a motor speed theta<(1)> by an estimate value Ahat of dynamical friction coefficient, and the value obtained by multiplying the position deviation by (-Jhat.Kp2) are added to obtain a torque command value tau, and a servo motor is driven by this torque command tau. Thus, the adaptive PI control system robust against the disturbance is obtained because of convergence of the phase surface Suf to 0. Since the phase surface Suf does not have any integral terms, the responsiveness is not changed even when the integral gain of the speed loop is increased, and the control strong against the disturbance is obtained.

Title: Air conditioner in underground space for residence
Inventor: KOMATSU HIDEKAZU
IPC: F24F11/02
Filed: 1984-05-04
Abstract: PURPOSE:To save energy by carrying out an environmental management within an underground room using only a ventilating fan without using the air conditioner when an indoor absolute humidity is higher than an absolute humidity of external air. CONSTITUTION:Measured values from respective sensors 5, 6, 7 and 8 inside and outside the underground room 1 are constantly input in a control part 9. In a case where an indoor absolute humidity is higher than a predetermined value, an external air absolute humidity is compared with the indoor absolute humidity. If the indoor absolute humidity is higher than the external air absolute humidity, the ventilating fan 3 is driven until the indoor relative humidity becomes lower than a predetermined value or the indoor absolute humidity becomes higher than the external air absolute humidity. Even if the indoor relative humidity is higher than the external air absolute humidity and the indoor absolute humidity is lower than the external air absolute humidity and the ventilating fan 3 is driven so that the inside and outside of the room have absolute humidities of the same degree, if the indoor relative humidity is still higher than the predetermined value, the dehumidifying operation of the air conditioner 4 is carried out until the indoor relative humidity becomes lower than the predetermines value. When the indoor relative humidity becomes lower than the predetermind value, the control part 9 determines whether the room temperature control is necessary or not. If necessary, the cooling or heating operation of the air conditioner 4 is carried out.
