Title: Optical disk device
Inventor: AKUTAGAWA RYUTARO
IPC: G11B7/00
Filed: 1987-05-28
Abstract: PURPOSE:To improve the repetitive characteristic by increasing the temperature of a part of a recording medium to be erased to a setting temperature by a light beam of a high power density region, and erasing the recording while the setting temperature is maintained by the light beam of a low power density region to prevent the deterioration of the performance of the optical disk due to thermal damage. CONSTITUTION:Erasure is applied by using an erasure beam with a beam profile where the temperature of the recording medium is increased to the setting temperature by the light provided with a high power density region at first, and the power is decreased gradually up to the lower power density region reaching the setting temperature at the steady-state to keep the setting temperature. Thus, an amorphous recording pit is converted into the state of liquid crystal, that is, unrecorded state on the recording film to apply erasure, and the film is not subjected to extreme high temperature even with the total power fluctuated because the temperature range of the setting temperature is set to a small power. Thus, the performance deterioration in the optical disk due to thermal damage is prevented to improve the repetitive characteristic.

Title: Magnetic bubble element
Inventor: HIROSHIMA MINORU
IPC: G11C11/14
Filed: 1978-10-30
Abstract: PURPOSE: To obtain a long-life, high-reliability and high-density magnetic bubble element by giving a multi-layer structure where a magnetic bubble magnetic film has a surface layer thinner than other parts in a side distant from a substrate and causing this surface layer to generate an anisotropic magnetic field smaller than other parts.  
     CONSTITUTION: Magnetic film 3 euquivalent to a normal bubble magnetic film is provided on nonmagnetic substrate 1, and surface layer magnetic film 4 which covers the surface of this film 3 thinly and has a small anistoropic magnetic field is provided, thereby constituting bubble magnetic film 2'. When electricity is supplied to the conductor loop of a bubble generator to generate a bubble nucleus, this nucleus grows continuosuly in magnetic film 3 and becomes normal bubble B. As a result, since bubbles can be generated with a current having a comparatively small amplitude even in case of a small magnetic bubble diameter, the conductor loop is prevented from being heated by a large-amplitude current and being too ruined  for use in a short time.

Filed: 1990-05-25
Abstract: PURPOSE:To accurately suppress vibration of a motor in a simple structure by sequentially varying the amplitudes of exciting currents to be supplied to phase windings of the motor at respective exciting coils, and moving the variation synchronously with the detected rotary position signal. CONSTITUTION:When a phase thetam and amplitude coefficient (m) to be supplied to a damping modulator MC are decided, it is divided into the case in which a rotary unbalance due to the deviation of the center of a shaft and the center of gravity is previously known and the case in which it is not previously known. In the former case, the phase thetam is fixed, and the coefficient (m) is varied in proportion to the rotating speed omegar obtained by differentiating a rotary position signal thetar. In the latter case, for example, there is no room for searching a rotary unbalance, or rotary unbalance is generated by an additive such as a tool, etc. In this case, the thetam and the m for minimizing the vibration are searched by scanning a table in a range of 0 - 2pi in terms of the phase thetam and in a range of 0 - 1 in terms of the coefficient (m).

Abstract: PURPOSE:To reduce the reluctance of a magnetic circuit and to increase the attraction force of an armature by making the face of the armature touch the end surface of a yoke at the position where the free end of the armature is separated from an electromagnet. CONSTITUTION:When a coil 12 has no current, the free end 10 of an armature 11 is separated from an iron core 14 by a restoring spring and a face 6 touches an end surface 5. When the current flows in the coil 12 in this state, magnetic flux PHI flows, e.g., in the direction shown by an arrow and the free end 10 of the armature 11 is attracted by the iron core 14 of an electromagnet 1 but no magnetic leakage exists and the magnetic efficiency of a magnetic circuit is good since the end surface 5 of a yoke 4 touches the face 6 of the armature 11. Since part of the magnetic flux PHI flows from a side surface 7 to a branch piece 8 in addition to the attraction force F1 of the iron core 14 to the free end 10, the branch piece 8 is attracted by attraction force F2 and the total force affecting the armature 11 is a resultant force F1 + F2.
