Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To prevent the waviness of the water distribution terminal pressure by applying the discharge pressure control to control the discharge pressure at a fixed level and then to control the water distribution terminal pressure at a fixed level. SOLUTION: The terminal pressure 5A measured by a terminal pressure gauge 5 is fetched to a terminal pressure control part 9 of a controller 1 and compared with the terminal pressure set value 2A that is previously inputted from a pressure setting unit 2. Based on this comparison result, the pressure difference 9A is outputted to a discharge pressure control part 8 from the part 9. The part 8 inputs the discharge pressure 4A measured by a discharge pressure gauge 4 and inputs the target discharge pressure value 8A to a rotational frequency control part 7 to keep the pressure 4A at a fixed level. The part 7 fetches the rotational frequency 3A from a pump 3 and compares it with the value 8A. Then the part 7 outputs the control value 3B to the pump 3 to control the rotational frequency of the pump 3 and to set the pressure 5A at a fixed level.  Thus, the controller 1 is controlled to set the pressure 5A at the value 2A and accordingly the outgoing pressure of the pump 3 is stabilized.

Title: Initialization method of information recording medium
Inventor: KOBAYASHI TADASHI
IPC: G11B7/26
Filed: 1990-11-30
Abstract: PURPOSE:To improve recording and erasing characteristics of phase transition type medium by making an inhomogeneous compsn. distribution of a recording layer by initialization. CONSTITUTION:Since a recording layer 3 as formed is amorphous, a light beam of certain intensity is condensed to irradiate recording tracks in the recording layer to crystalize, and then the recording layer is initialized to have inhomogeneous compsn. The initialization is performed by irradiating the optical disk with a light beam having an intensity level to melt the recording layer 3 while rotating the optical disk slowly. The recording layer 3 is molten and slowly cooled, during which the segregation of structural elements is caused mainly in the thickness direction of the recording layer. When the compsn. is inhomogeneous, crystalization can be effected fast and the segregating structural elements make such a compsn. which more reasily gives an amorphous state. Thereby, recording and erasing characteristics of the phase- transition type medium can be improved and the initialized state is suitable for overwriting. Protective layers 2, 4 consist of such a material having high thermal conductivity, and the recording layer 3 consists of a material which easily changes into amorphous. It is effective to form the layer 3 thin and the protective layer 4 thin adjacent to a reflecting layer 5.
