Filed: 1992-09-22
Abstract: PURPOSE:To easily form tracks by an optional track pitch by continuously forming grooves having a prescribed width radially from the center of a magneto-optical disk, measuring the synchronization of the width of the grooves and controlling tracking so that the cycle is a prescribed value. CONSTITUTION:In the magneto-optical disk 1, the plural grooves are formed radially from the center. That is, two edges composed of a front edge and a rear edge are formed and the L of the grooves at the time is fixed regardless of positions in the radial direction. Since the disk 1 is formed in such a manner and is provided with the grooves and mirror parts, an entire magneto-optical film is provided and data are magneto-optically recorded not only on the mirror parts but also on the grooves. Since the level of RF signals declines near the edges in such a manner, the level is monitored and the positions of the edges are detected. Concretely, the cycle of the front edge and the rear edge is detected at a detection circuit 7 using output pulses from a pulse detection circuit 5 with a clock supplied from a switch 12 as a reference. That is, a track formation target value is outputted from a target value generation circuit 10.

Abstract: PURPOSE:To maintain a high exhaust gas purifying efficiency by performing feedback control based on the added signal for which an air-fuel ratio signal is proportionally amplified at a gain corresponding to an oscillating signal and the driving state around a signal level for which the air-fuel ratio signal is integrated as a center. CONSTITUTION:In an ECU7, a signal from an air-fuel ratio sensor 12 is compared in a standard signal forming circuit 21 and in a comparer 20, and the discriminated signal is proportionally amplified by a proportional amplifier 23 at a gain corresponding to an engine driving state from a CPU 70, and a rectangular wave oscillating signal is output by an oscillating signal generating circuit 24, around an output level of an integrator 22 as a center, its amplitude correspondent with a gain signal. Output signals of the circuits 23, 24 are added by an adder 25, and a fuel emission control signal is determined through a signal of each sensor by the CPU 70, injectors 8 being driven in order through a driver 74. Air-fuel ratio feedback control is thus possible sufficiently taking advantage of exhaust gas purifying ability as much as a catalyst converter of engine exhaust system can achieve, and high exhaust gas purifying effect in a wide air-fuel ratio range can be maintained thereby.

IPC: C21C7/00
Filed: 1996-10-21
Abstract: PROBLEM TO BE SOLVED: To prevent the clogging of a nozzle by regulating the number of remaining alumina having a prescribed grain diameter in molten metal. SOLUTION: In the figure, the relation between the number of the alumina having >=10μm in a sample taken from the molten metal poured into the immersion nozzle and the developing condition of the nozzle clogging, is shown. In this figure, the nozzle clogging has clear correlation with the number of the alumina and it can be prevented to develop the nozzle clogging by indexing and controlling this number of the remaining alumina. That is, the development of the nozzle clogging is prevented by reducing the number of the remaining alumina to <=1 pieces/cm<2> (60,000 pieces/kg) and the casting can be stabilized. Further, in order to melt such a molten metal, in the case of being <=4% T.Fe in slag before Ca-treatment, the remaining alumina having >=10μm size in the molten melt can be controlled to <=1 pieces/cm<2> .

Title: Fluid deflecting device of heat exchanger
Inventor: IGARASHI KAZU
IPC: F28F1/12
Filed: 1984-12-26
Abstract: PURPOSE:To contrive to enhance the heat exchange efficiency of the titled device by increasing the time and area for fluid to contact with heat transfer pipes by a structure wherein fine wires, some portion in cross section of each of which is of circular arc, are extended in the direction so as to intersect heat transfer pipes adjoining to one another and at the same time arranged so that the circular arc part of the fine wire contacts with the outside of the heat transfer pipe. CONSTITUTION:The stream line of heating fluid is disturbed by fine wires 6. The heating fluid flowing just beneath the fine wires 6 parts itself right and left as indicated with the arrows by colliding against the fine wires 6, resulting in producing the stream ascending along the fine wires 6 in the peripheral direction on the surface of the heat transfer pipes 1, resulting in prolonging the time for the heating fluid to contact with the heat transfer pipes 1. In addition, because the cross section of the fine wire 6 has a circular or elliptic form, at least the portion of the contour of section of the fine wire, with which the heat transfer pipe 1 contacts, is arcuate, resulting in producing the line or point contact between the fine wire 6 and the heat transfer pipe 1. Consequently, the fine wire 6 does not bring the decrease of the contact area between the fluid and the surface of the heat transfer pipe 1. The heat exchange efficiency between the fluid and the heat transfer pipe can be enhanced, because the above-mentioned structure increases the time and area for the fluid to contact with the heat transfer pipe and at the same time tends to refresh the boundary layer on the heat transfer pipe.

Filed: 1984-12-29
Abstract: PURPOSE:To miniaturize a device for he titled method by changing the drive method of a ringer circuit to use a lighting power supply of a message waiting lamp in common with a ringer power circuit. CONSTITUTION:Relays rl1, rl2 are in operating state at ringer transmission and a rectangular wave with 16kHz with 50% duty is transmitted from a terminal Q7 of a counter 12. On the other hand, a 16Hz intermittent signal is sent from a control circuit 11 and a 16kHz signal intermitted by 16Hz is fed to a base of a transistor (TR)18 via NAND circuits 13, 14. A 16kHz intermittent current flows from a +24V power supply thereby. An induced signal at the secondary winding of a transformer 19 is smoothed to ring intermittently a bell 5. With a message waiting lamp lighted, a relay is activated and outputs at terminals Q4-Q5 of the counter 12 are added to send a rectangular wave signal in 16kHz with <=50% duty. While a signal of logical H is sent from the control circuit 11, a continuous 16kHz signal turns on the TR18. Thus, a 16kHz current flows from the 24V power supply and the induced signal at the secondary side of the transformer 19 lights a lamp 6.

Abstract: PURPOSE:To improve productive efficiency by drawing a starting high carbon steel stock to the prescribed dimensional range with the carbon content of the stock reduced to a value lower than that of the final composition by a specific percentage and then performing carburization and diffusion annealing. CONSTITUTION:In the case of manufacture of fine wires of high carbon steel stocks containing respective specific percentages of Cr, Mo, W, and V and 0.5% or more carbon, the carbon content of starting stocks is previously reduced by 0.2-0.5% lower than that of the final composition. The starting stock containing a reduced carbon content is hot rolled and drawn down to a diameter of 2mm or less. Then, the carbon content is increased by gas carburization and others up to a required value and variations in the carbon content in a wire stock cross section is minimized by diffusion annealing. The productive efficiency of high carbon steel fine wires is increased because of working with a reduced carbon content.
