Title: Manufacture of quenched foil for truncated conical ring joining member, device therefor, and manufacturing nozzle
Inventor: SATO YUICHI
IPC: B22D11/00
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To provide a quenched foil of uniform thickness in the width direction by increasing the width of a slit-shaped opening of a nozzle from a mirror diameter side of a tapered surface of a single roll toward the major diameter side. SOLUTION: A molten metal 8 in a crucible 4 is jetted onto a tapered surface 2 of a revolving single roll 1 from an opening 6 of a nozzle 5. The molten metal 8 is quenched to be a quenched foil 9, and peeled with the air blowing from a peeling nozzle 10. The width of the opening 6 is gradually increased from the minor diameter (b) side of the single roll 1 toward the major diameter (a) side. Because the feed of the molten metal 8 to the tapered surface 2 is appropriate corresponding to the peripheral speed at every part from the major diameter (a) side to the minor diameter (b) side, the thickness of the quenched foil 9 is uniform. A truncated conical ring is manufactured using the quenched foil 9.  Because the truncated conical rings to be inserted in joining surfaces of tubes are uniform in thickness, the joining surfaces of the tubes are closely attached to the rings over the whole surface. The joining strength is improved by the joining with excellent accuracy.

Filed: 1995-06-13
Abstract: PURPOSE: To easily and quickly reduce useless margin parts as much as possible corresponding to the variable power rate of output by providing a means for switching a printing direction by the variable power rate of the output. CONSTITUTION: A prescribed program is stored in a storage device 3 and a controller 1 controls a variable power printing processing and a plural-page printing processing by an output device 5 corresponding to the program. Also, an input device 2 is provided with a function for setting the variable power rate. For instance, when the variable power rate (reduction ratio) relating to setting is defined as N, in the case of 1/2 to the power of an even number (including 0) >=N>1/2 to the power of an odd number, the printing direction is not switched and printing is performed by the variable power rate relating to the setting.  In such a manner, since whether or not the longitudinal/lateral changeover of the printing direction is to be performed is automatically discriminated from the variable power rate relating to the setting and printing and output are performed by the variable power rate relating to the setting, a user is not required to change the direction of output form so as to reduce the useless margin parts and the useless margin parts are easily and quickly reduced as much as possible.

Title: Production of low-nitrogen steel
Inventor: TOZAKI YASUYUKI
IPC: C21C5/40
Filed: 1985-08-01
Abstract: PURPOSE:To avoid the generation of a negative pressure in an OG type converter and to prevent the increase of the content of N in a molten steel by the intrusion of air therein by connecting a gas supply pipe to the mid-way of a waste gas hood of the converter and blowing gas not contg. N into the hood at the time when the flow rate of the waste gas is low at the end period of refining. CONSTITUTION:The molten iron in the OG type converter 2 is subjected to oxidation decarburization by oxygen top blowing refining using a lance 1 and is thereby refined to a steel. The waste gas contg. CO is sucked by a suction fan 4 and is thus recovered. The amt. of the CO-contg. waste gas by the oxidation of C is small at the end period of the decarburization refining and the negative pressure is developed in the converter by the suction of the waste g as by the suction fan 4, by which the external air is intruded into the converter. Then, the molten steel absorbs the N in the external air to becomes high nitrogen content. The gas such as CO, CO2 or Ar which does not contain N is supplied from the gas supply pipe 10 provided to the hood 3 to maintain the inside of the converter under the positive pressure at the end period of refining when the amt. of the waste gas is small in order to prevent the above-mentioned increase of N. The intrusion of the external air by the negative pressure is obviated and the increase of the content of N of the molten steel in the converter by the absorption of the N in the intruding external air is prevented. The low-nitrogen and low-carbon steel is thus produced.

Title: Fuel injection valve
Inventor: IKEDA HIROICHI
IPC: F02M53/04
Filed: 1981-10-23
Abstract: PURPOSE:To prevent sulfuric acid corrosion and carbon accumulation in a fuel injection valve for an internal combustion engine by providing a heater to heat a contacting face with burned gas within a range of 300-700 deg.C inside the main body of the injection valve. CONSTITUTION:A connecting hole 7 is bored in an injection valve main body 1 for penetrating into a cap 6, and a code 9 of a heater 8 is inserted through this hole. When surfaces of a nozzle tip 2 and the cap 6 are heated over 300 deg.C by this heater 8, no sulfuric acid corrosion occurs by any kind of fuel oil. Since the evaporation speed is increased, fuel particles are prevented from touching on the surfaces, and carbon is difficult to stick. Even if the carbon is stuck a little, a high temperaure on surfaces burns the carbon, and reduces its accumulation. This construction permits to maintain good atomization.

Title: Method for processing defective sector in optical data recording/reproducing device
Inventor: KIMURA SATORU
IPC: G11B20/10
Filed: 1987-07-08
Abstract: PURPOSE:To shorten the access time of a substitutive sector and to improve data recording efficiency by recording defective sector information in a disk area, and at the time of recording data in the disk, using the succeeding sector as the substitutive sector when a defective sector is generated. CONSTITUTION:The generating position of a defective sector is previously inspected and a logical address/physical address conversion map is formed from the information of the defective sector and recorded in an area formed on the inner or outer periphery of the disk 1. In case of writing data in the disk 1, the recorded conversion table is read out, and when a sector (k) in which data are to be written is a defective sector is decided, data writing control is transferred to the next sector k+1. Since the substitutive sector k+1 is arranged next to the defective sector (k) on the same track in said control, the time required for accessing the substitutive sector k+1 is shortened. Since the substitutive sector can be set up to a minimum value required, the data recording efficiency can be improved.

Title: Indicator for vehicle
Inventor: SAIJIYOU MUNETOSHI
IPC: G01C23/00
Filed: 1990-06-28
Abstract: PURPOSE:To concentrate driver's attention to driving to improve safety by controlling driver's recognition to displayed service information when traveling at higher than a constant speed is detected. CONSTITUTION:A display device 41 has a display screen 40 for displaying service information such as a map, while a transmission plate 42 comprises a transmission type liquid crystal wherein curvature varies according to applied voltage. When a vehicle speed at a predetermined value or higher is detected, a control means controls the voltage applied to the plate 42, thereby varying the curvature of the liquid crystal when light transmits through the plate 42 and resulting in a change in an advance direction of the light. Therefore the displayed information is recognized from a range A when the vehicle stops and enters a view field from a driver's eye point D to be recognized by the driver, while the information changes to be recognized from a range B during a travel of the vehicle so that it comes off the view field from the point D and the driver cannot recognize it. Therefore the driver's attention can be concentrated on driving so as to improve safety.
