Title: Treatment for anti-stress corrosion cracking in two-phase stainless steel
Inventor: MIZOBUCHI SHIYOUTAROU
IPC: C25D9/00
Filed: 1978-03-14
Abstract: PURPOSE: Micro-cathode current is passed through two-phase stainless steel, thereby forming a coating layer having anti-stress corrosion property which is maintained after it returned to natural potential.  
     CONSTITUTION: Micro-cathode current (5 to 10 mA/cm 2 ) is passed through two- phase austenite-ferrite stainless steel for 5 minutes, thereby forming a coating layer having anti-stress corrosion cracking, such property being maintained after the current is stopped for a period of time remarkably longer, as compared to non-treated material. For example, the lowest limit stress value for anti-stress corrosion cracking is 50 kgf/cm 2  for the treated material, while for non-treated material only 21 kgf/cm 2  is obtained. In another example, the non-treated material failed after 2 hours at a certain load, while the treated material maintained its integrity without failure after 100 hours of current stop at the same loading condition.

IPC: G11B27/10
Filed: 1984-02-20
Abstract: PURPOSE:To prevent variance of an access time due to a reproducing speed to improve the operability by setting the reproducing speed to a standard speed temporarily and restoring this reproducing speed after the end of access if an access signal is inputted in the reproducing state where the reproducing speed is increased or reduced. CONSTITUTION:In case that a volume VR2 is operated manually to increase (or reduce) the reproducing speed, a switch S is switched to the side of a contact (a), and the frequency of a variable oscillator 13 set by the volume VR2 is inputted as a master clock signal to a microprocessor 6. At this time, since a switch S1 is opened, transistors Q1 and Q2 are driven and a relay RY inverts a switch S2 when an access command is inputted from a mechanical computer 12. Then, a control voltage from a volume VR1, which is so adjusted that a standard master clock signal (8.6436MHz) is generated, is supplied to the variable oscillator 13, and the reproducing speed of the disc is changed to the standard reproducing speed. When access is completed in this state, the control voltage of the volume VR2 is supplied to the variable oscillator 13 again through the switch S2, and the disc is returned to the reproducing speed mode.
