Title: Protective circuit against overvoltage and surge in hard disk drive
Inventor: KIM JAE JUNE
IPC: H02H11/00
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To protect the circuit components inside a drive by applying the level of a second power source to the inner circuit which is extremely much lower than the level of the first power source, using the first power source applied to the input end of the second power source, when overvoltage is applied to the input end of the first power source, with the first and second power sources applied in reverse. SOLUTION: In the case of reversely applying voltage, the power of +5 V applied through the input end 24 to a +12 V power source is applied to the gate terminal of an NMOS transistor 12, being divided by resistors 14 and 16 for voltage division, and this voltage partially turns on an NMOS transistor 12. Therefore, the power of +12 V applied through the input end 22 of the +5 V power source drops in voltage by the components of its resistance, when supplied to the inner circuit 26 of a hard disc drive through an NMOS transistor 12, so that the voltage of the source terminal falls below +5 V. Accordingly, the voltage supplied to the inner circuit 26 of the hard disc drive is free of the possibility of damaging the inner circuit.

Abstract: PURPOSE:To prevent weld splash and peeling-off of a blackened film by applying blackening treatment at a predetermined temperature to a frame-holder assembly not yet subjected to prescribed blackening treatment after welding, thereto a formed mask not yet subjected to the blackening treatment. CONSTITUTION:A formed mask is cleaned, followed by a blackening treatment at a temperature of 580 to 650 deg.C in stream or in oxidizing gas atomosphere in order to produce a shadow mask body. By means of a process of press molding, a mask frame being L shaped in its cross-section is formed from a carbon steel plate of the prescribed thickness, and then said mask frame is cleaned or nickel plated after cleaning. Then, a frame holder made of a stainless steel containing 10% or more of Mn and heat-treated in a temperature ranging from 450 to 520 deg.C is welded at the prescribed position of the mask frame in order to produce a frame-holder assembly. Next, the frame-holder assembly is subjected to blackening treatment in stream or in oxidizing gas atomosphere at the temperature from 580 to 650 deg.C. The formed mask subjected to blackening treatment and the frame-holder assembly subjected to the blackening treatment are welded together to produce a shadow mask.

Filed: 1984-07-24
Abstract: PURPOSE:To simplify the constitution by selecting a speed for shifting a head with respect to a recording medium among plural different speeds and modifying a shifting speed only when the time interval of an operation is shorter than the preset time. CONSTITUTION:When a switch 19 is decided to be turned on with the aid of input data from an input circuit 14 at the time of recording, a discriminating circuit 135 instructs a recording control circuit 136 to act and controls a switching circuit 10, and simultaneously gives instructions of moving a head 6 with respect to a head moving control circuit 137. Then, the discriminating circuit 135 orders a memory 15 to store track number data and simultaneously permits a display 18 to display the track number. When the switch 20 is discriminated to be turned on, the discriminating circuit 135, at the time of reproduction, connects the switching circuit 10 to the reproduction side. Then the head moving control circuit 137 controls a head moving mechanism 11 to shift the head 6, and simultaneously outputs the track number data at this time to the memory 15. Thus the constitution can be simplified and its cost can be reduced.

IPC: B21K1/08
Filed: 1990-06-15
Abstract: PURPOSE:To securely prevent a flaw caused by a piping defect from remaining at a shaft end part of a forging product by forming a dead boss part having partially large outer diameters at the end part in the direction of a shaft line of a cross roll forming stock. CONSTITUTION:The forging stock 6 is pressed and elongated from the central part toward both end parts in the direction of a rotary shaft line to be formed into a shape having a comparatively fine bar-like shaft end part 6a and an outer diameter changing part 6b. In cross roll forming, a dead boss 6c having partially large outer diameters is formed by a groove 7b in the circumferential direction of a roll die 7. Since the reduction ratio of cross-sectional area of the forging stock 6 is lowered in the dead boss part 6c, the extension ratio of the outside wall part is reduced at the end in the direction of a shaft line and the piping defect 6d generated in the central part is shallowed drastically. Further, the piping defect 6d stops at the dead boss part 6c and does not reach the central part of the shaft end part 6a at the inner part of the boss part.
