Title: Method for overwriting rewritable optical information recording medium
Inventor: MIYAZONO YASUSHI
IPC: G11B7/00
Filed: 1991-03-20
Abstract: PURPOSE:To improve an erasing ratio by using the output waveform of a laser beam used for recording and reproduction by superposing a recording laser output pulse and a pulselike laser output having an interval narrower than that of the recording laser output pulse. CONSTITUTION:By using the laser output waveform for which the pulselike laser output Pb2 having the narrower interval than that of Pw is superposed for the recording laser output pulse Pw, recording and reproduction are performed. Namely, a bias laser output which is conventionally constant between the recording laser output pulses is partly increased and the temperature of a recording film is set to be the same or above the melting point. Thus, the crystallization in coarse grains of the recording film is enabled over a recording track in a wide range, and the crystal grain size of the erased marked part approaches the crystal grain size of other parts. Consequently, the erasing ratio by means of overwriting is improved.

IPC: G03G21/10
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To obtain specified image density in a short time by providing an electric field forming means forming electric field by which toner particles in developer are moved in a direction where they go away from a developing roller on an area (pre-area) carrying the developer from a developer reservoir part to the surface of a latent image carrier. SOLUTION: This device is provided with the electric field forming means 8 forming the electric, field by which toner particles in the developer are moved in the direction where they go away from the developing roller 3 on a pre- developing area 6. After the developer drawn up from the developer reservoir part 5 by the roller 3 is carried to the area 6, it reaches a developing gap area 7, where development is performed to an electrostatic latent image. In the case the toner particles have negative electrostatic charge, the means 8 forms the electric field in a direction shown by an arrow for the area 6. Since the toner particles are moved in the direction where they go away from the roller 3 by the action of the electric field, density distribution where the toner particles are attracted to the level of the developer is obtained.

IPC: B23Q15/00
Filed: 1990-03-30
Abstract: PURPOSE:To find the viscous friction coefficient of a positioning device consisting of rotary and direct acting mechanisms at each of rotary and direct acting sides while keeping an assembled state by finding a resonance value and a resonance frequency from frequency responsiveness at a direct acting mechanism side, and calculating them with the weight of a carrying material. CONSTITUTION:The viscous friction coefficient of the rotary and direct acting mechanism which converts the rotary motion of a motor 1, etc., to linear motion via a converter comprised of a ball screw 3 and a nut is identified. In such a state, the resonance frequency and the resonance value are read by measuring the frequency characteristic of a state at a carrying material side for that of a rotary driving means side, and viscous frictional resistance at a direct acting system side is calculated from the resonance frequency and the resonance value and the weight of the direct acting system side including the carrying material 4. Thereby, the viscous friction coefficients of the rotary and direct acting mechanisms can be found with high accuracy and without assembling complicated algorithm in a state where they are separated. Also, the coefficient can be identified in a form of positioning device as a finished product in which both the rotary and direct acting mechanisms are assembled.
