Title: Thin diamond film, its preparation and thermal head provided with the same thin diamond film
Inventor: BABA KAZUO
IPC: B41J2/335
Filed: 1992-01-24
Abstract: PURPOSE:To provide a thin diamond film having good surface properties, its preparation and a thermal head provided with the thin diamond film. CONSTITUTION:A substrate is dipped in an organic solvent solution of an alkylchlorosilane (according to a substrate dipping process 1) and passed through a substrate drying process (2) and a substrate annealing process (3) into a film forming process (4) to form the objective thin diamond film. Thereby an organic solution of an alkylchlorosilane is treated with an enzyme on the substrate surface prior to lamination of the thin diamond film and an alkyl group is bound to the substrate surface. As a result, the affinity between the alkyl group and a hydrocarbon compound which is a raw material for carrying out CVD method is increased and formation density of a diamond crystal nucleus is increased.

Title: Printed board and manufacture thereof
Inventor: NAGAI TOSHIHIRO
IPC: H05K1/11
Filed: 1991-01-31
Abstract: PURPOSE:To prevent a thermal stress from being concentrated by a method wherein a through hole is formed in an insulating substrate having conductor parts on its surface and chamfering parts are formed on the opening part of the hole by a chamfering processing. CONSTITUTION:A through hole 5 is formed in an insulating substrate 2 formed with such conductor parts 3 and 4 as a copper-clad laminated board on its whole surface by an NC drilling machine or the like and thereafter or simultaneously with the formation of the hole 5, chamfering parts 9 are formed by a chamfering processing. A conductor plated part 6 is formed on the inner peripheral part of the hole 5, the parts 9 and in the vicinity of the opening part of the hole 5 by copper plating. After that, a circuit pattern is formed on the parts 3 and 4 and conductor parts 7 by an exposure, a developing, an etching and the like. Thereby, as corner parts 8 of the opening part of the hole 5 are removed by a chamfering processing, a thermal stress due to a difference in thermal expansion is dispersed even in the case there is heat input, such as soldering or the like, and the generation of a crack in the conductor plated part 6 is prevented.

Title: Back-up controller
Inventor: TAKAMI ISAO
IPC: G05B23/02
Filed: 1983-01-26
Abstract: PURPOSE:To continue an automatic control despite a fault of an analog control circuit by providing a digital control circuit having the same arithmetic function as the analog control circuit and monitoring and processing the output deviation between both circuits. CONSTITUTION:An analog control circuit 11 supplies an input signal (a) to perform a PID operation and delivers the signal (a) via a switch 12. While a digital control circuit 13 also performs the same operation as the circuit 11 and has the possibility that the integration result of minute arithmetic errors has a big difference from the arithmetic result of the circuit 11. Therefore a coincidence circuit 14 feeds periodically the output deviation between the circuits 11 and 13 back to the circuit 13 to obtain the coincidence between the outputs of both circuits. At the same time, a fault diagnosing circuit 15 compares the outputs of circits 11 and 13 with each other. When the deviation between these outputs is larger than the prescribed value, the circuit 15 delivers a mimic signal (b) to the circuit 13 to check whether the output of the circuit 13 is normal or not. If the output of the circuit 13 is normal, the circuit 15 decides a fault of the circuit 11 and delivers a switch signal (c) to the switch 12 to perform an automatic control with the output of the circuit 13.

Abstract: PROBLEM TO BE SOLVED: To excellently radiate heat generated from a stator core by providing a plurality of slits on the outer periphery of the core along the peripheral direction by changing the positions of the slit in the laminated direction of the slits. SOLUTION: A plurality of slits 5 is provided on the outer periphery of a stator core 2 for electric rotary machine along the peripheral direction by changing the positions of the slits 5 in the laminated direction of the slits.

IPC: C21C7/00
Filed: 1994-02-03
Abstract: PURPOSE:To increase purity of stainless steel and to prevent wire breakage at drawing to extra fine wire by adjusting a concentration of Al and a basicity of molten slag to the specific values in refining stainless steel. CONSTITUTION:A stainless steel is produced from raw materials of steel scrap, Fe-Cr, etc., after decarburized/refined by adding Fe-Si as a reducer and CaO as a slag making agent into molten slag. The basicity of molten slag is adjusted to 1.2-1.8 and Cr2O3 in molten slag is reduced by Fe-Si so as to be recovered in stainless steel. Subsequently, this molten stainless steel is transferred to a ladle and the powdery flux containing CaO, CaF2 as essential components is blown therein with an inert gas such as Ar gas. Al content in the molten stainless steel is made to <=40ppm by significantly reducing non-metal inclusion, in particular, the quantity of Al2O3 with poor elongation, thus wire breakage at drawing to extra fine wire is reduced.

Filed: 1984-01-27
Abstract: PURPOSE:To measure a speed offset accurately in a stable speed state and to correct the speed of a controlled system automatically to a target speed accurately by using an acceleration signal for the speed offset correcting means of the controlled system. CONSTITUTION:A frequency generator 2 generates a frequency signal FG proportional to the rotation of the motor 1 of a body to be controlled and sends the signal to a speed control circuit 3. A circuit 3 generates a pulse at every period of the signal FG to count 10 how many clock signal pulses are present in the period FG, and the counted value is D/A-converted 12 and inputted to an adder 6. A speed correcting circuit 4 detects 16 the acceleration with pulses from the circuit 3, closes switches 21 and 25 when the acceleration becomes zero to detect 17 the period error of the signal FG, and adds 20 the error value to a reference preset value 19 to supply an initial value to a counter 10. A phase control circuit 5 converts 24 the comparison value 23 between a reference signal REF and the detection signal of a phase detector 8 from digital to analog and controls the motor speed to a constant value on the basis of the value of addition 6 between the conversion signal and the signal of the circuit 3.

Abstract: PURPOSE:To obtain a nonoffset type toner by containing a crosslinking agent and low mol.wt. polyolefin in a polymer composition and using an inorg. dispersant which charges to the polarity opposite to that of the polymer composition in water, in performing suspension polymerization in water. CONSTITUTION:Low mol.wt. polypropylene is added to a polymerizable monomer such as styrene and the mixture is subjected to heat treatment. A crosslinking agent such as triethylene glycol, a coloring agent, magnetic powder, a charge control agent, and an anionic or cationic polymerizable monomer which charges the polymerization composition to one polarity or a hardly-water-soluble amine and further a polymerization initiator, etc. are added to this liquid, whereby the polymer composition is obtained. The polymer composition is added to the dispersion of a dispersant, such as colloidal silica, which charges to the polarity opposite to that of the polymerization composition in water, whereby suspension polymerization is accomplished. This yields the spherical particles in which the low mol.wt. polyolefin is contained in the form of finely ground particles.
