Title: Tube for heat exchanger and its production
Inventor: KONYA HIROKI
IPC: F28F1/40
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To obtain a tube for a heat exchanger with which a fluid peeling effect at the wall surface of the tube of a heat medium flowing therein is made obtainable by microruggedness and heat transfer efficiency is excellent as the flow of the heat medium is made turbulent by forming the ruggedness on the inside surface of the tube by ironing of its outside diameter. SOLUTION: A tubular member 10 of the diameter larger than the outside diameter of a product is produced by extrusion forming of an aluminum alloy. The member is successively introduced to a die 11. At this time, the aluminum alloy is preferably completely recrystallized by previously subjecting the alloy to an O material treatment. The tubular member 10 is drawn by inserting the member into a die 11 without interposing a plug therein. The outside diameter of the tubular member 10 is then reduced by the drawing and the thickness corresponding to its reduction component is pushed toward the inside surface. The pushed thickness components interfere with each other within the reduced area and the inside surface is roughened, by which the microruggedness 12 is formed toward a longitudinal direction.

IPC: H02M1/00
Filed: 1995-02-27
Abstract: PURPOSE: To relax extreme complication of the circuitry owing to application of a snubber energy regeneration circuit by detecting the regenerating current flowing through a resonance circuit and making a decision that the circuitry is faulty if the detected current exceeds a set level. CONSTITUTION: A snubber circuit 30U comprises a first auxiliary switch 6U, a snubber capacitor 14U, a snubber diode 16U, a snubber resistor 15U, a first reactor 5U, a first regenerative transformer 7U, diodes 13U1-4, and a current detector 18U. A GTO1U is turned ON when the winding of the reactor 5U is short-circuited, for example, followed by turn ON of the auxiliary switch 6U with a small time lag. Since a regenerative current flowing through the closed circuit of the primary winding 5U, 4U of the 4U, 1U, 6U, 18U and 7U exceeds a set overcurrent level, an SC signal is outputted to set a flip-flop. Consequently, a faulty signal goes '0' and an abnormality is detected thus realizing significant simplification of the gate system.

Title: Manufacture of magnetic disk
Inventor: KURODA TAKATOSHI
IPC: G11B5/84
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence and the breeding of live bacteria in washing liquid and to avoid the adverse effect such as glide characteristic reduction caused by the formation of the thin film made by the remainings of the dead bodies and the excrement from bacteria on the surface by adding hydrogen peroxide having a specific concentration to the washing liquid used in a washing process. SOLUTION: Hydrogen peroxide is added to the washing liquid used in a washing process to the tune of 5 to 30 weight ppm range, preferably 5 to 20 weight ppm. If the addition of the hydrogen peroxide is less than 5 weight ppm, the prevention of the occurrence of live bacteria is less effective. On the other hand, if the addition of the hydrogen peroxide is more than 30 weight ppm, no increase is expected to prevent the occurrence of bacteria and an additional waste liquid process must be conducted. By adding a proper amount of hydrogen peroxide, the bacteria in the washing liquid are completely eliminated to realize bacteria free liquid. Using the washing liquid for the washing process of substrates, the reduction in the glide characteristic caused by live bacteria is prevented.

Title: Magnetic disc device
Inventor: TAKIGAMI HIROBUMI
IPC: G11B21/10
Filed: 1985-02-27
Abstract: PURPOSE:To attain accurate reading and writing by generating and storing an eccentricity correcting data to let the head trail on the eccentricity-correcting track and thereby controlling the head to trail on the target track in accordance with the positional information of the target track. CONSTITUTION:When a read/write signal that specifies an optical track is inputted to an eccentricity-controlling circuit 3 from a magnetic disc control circuit 7, the circuit 3 obtains from a seek circuit 8 and the control circuit 7 an information of the target track, and corrects the eccentricity-correcting data in accordance with the obtained information, and further generates an adoption data to let a head 50 trail on the track and supplies it to an eccentricity-correction-value generating circuit 5. The adoption data can be generated, for instance, by multiplying the eccentricity correction data by a coefficient produced in accordance with the data track positional information. Because the seek circuit 8 lets the head 50 transfer in accordance with the adoption data, the head 50 at all time is positioned on the targeted track. As a result, the reliability of the read/write data does not lower even after eccentricity occurred.
