Title: Optical information recording method and optical information recording medium
Inventor: SUZUKI YOSHIO
IPC: G11B7/243
Filed: 1995-05-23
Abstract: PURPOSE: To decrease overriding jitters and to lower a bit error rate by using four elements consisting of specific compsns. as the recording layer material of a phase transition type optical information recording medium by a bit edge recording method. CONSTITUTION: The recording layer of the phase transition type optical information recording medium consists of at least the four elements; Ge, Sb, Te and Bi and the compsns. of these four elements are expressed by [formula 1]. Recording information is recorded on such information recording medium by the bit edge recording method to make the 1 of code strings correspondent to the position of the front ends and rear ends of recording marks. In the formula, 0.1<=X<=0.6, 0.5<=Y<=0.9, 0<Z<=0.5, where X, Y, Z respectively denote carbon atoms. As a result, the recording medium is exceedingly improved in recording density as compared with the conventional methods and further, the bit edge recording to exhibit the jitter characteristic sufficient for practicable use as the overwriting characteristic by a single beam is made possible.  The bit error rate is thus lowered to the extent of having no problems in practicable use.

Filed: 1988-05-23
Abstract: PURPOSE:To prevent elements such as semiconductors from being deteriorated or damaged or changing with respect to characteristics due to the abnormal rise of temperature inside a device by detecting the rotation speed of an exhaust heat fan and stopping the heating of a heating means when the rotation speed is lower than a prescribed value. CONSTITUTION:In a CPU 1, the exhaust heat fan 9 is driven after A1 set to a 'high' level, and an electric heat generator 2 is heated after a port A0 set to a 'high' level. Next, the point A0 is checked, and when the electric heat generator 2 is being heated, whether the rotation speed of the exhaust heat fan 9 is normal or not is checked at a port A2. When it is detected that the rotation speed of the exhaust heat fan 9 is abnormal (lower than the prescribed value), the ports A0 and A1 are set to a 'low' level and heating of the electric heat generator 2 is stopped. As a result, elements such as semiconductors which are sensitive to heat in an image recorder can be prevented from being deteriorated or damaged or changing with respect to the characteristics.

Abstract: PURPOSE: To effectively avoid resonance of vane groups of steam turbine etc. by selecting the position of cutting the connecting member after coupling and assembling the group of vanes with the shroud at the vane top and midle-part-connecting member.  
     CONSTITUTION: Vanes 2 planted on a shaft are connected at their top by means of shroud 4 and are also connected at the middle by a circular fastening member 3' like stab or wire etc. The fastening member 3' which is for enhancing the rigidity of the vanes and adjusting intrinsic frequency of vane groups, is cut into 2 pieces at the place which is selected as suitable for avoiding resonance based on measured data, after assembling. The resonance can be avoided because the intrinsic frequency of fundamantal vibration type decreases by 20W30cps. The place to be cut is calculated by using the measuring data, but should be within the range which is allowable from the point of view of the rigidity.

Abstract: PURPOSE:To reduce variability of the peeled dimensions by bringing a discharging surface of a discharge electrode into contact with a covered with at a certain angle and by adding an insulator to the contacted part of the electrode with the wire the moment the covering is peeled by discharging between the electrode and wire. CONSTITUTION:High voltage is applied between a discharge electrode 1 and a covered wire 3, where a discharge phenomenon is caused. At this moment, an insulator 2 is added to the tip of the discharge electrode 1. The discharge phenomenon starts from the tip 3a of the wire 3. Along with the discharge the covering of the wire 3 is melted,vaporized and peeled. Conditions are set beforehand for the time discharge voltage is applied, in which the time is set the covering is fully peeled to a contact point 4 of the insulator 2 with the wire 3. From the tip 3a of the wire 3 the covering is peeled in sequence up to the contact point 4. The discharge phenomenon continues as it is during the period the time is set for applying the discharge voltage. The covering of the wire 3 is, however, prevented from being peeled on and after the contact point 4 interrupted by the insulator 2.
