Title: Developing toner and method
Inventor: RICHIYAADO JIYON TOURERIIBUEN
IPC: G03G13/10
Filed: 1978-11-17
Abstract: PURPOSE: To make it possible to produce by a relatively simple method the toner material, which contains no air pollutant and which has its fixing property improved, by coating the liquid droplets containing a color agent with a group of hydrophobic organic substance particles.  
     CONSTITUTION: A watersoluble dye or an agueous dispersion of pigment is dissolved or dispersed in a water medium. To the aqueous solution or dispersion thus obtained, a hydrophobic organic substance particles having a diamerter of 5 to 50 mμ such as calcium stearate are added. A high shearing force is applied to the resultant mixture in an apparatus such as a waring blender so that the respective droplets having a desired color agent are produced and are instantly coated with the hydrophobic organic substance particles under a discontinuous layer. Those droplets may contain a fixation promoting agent such as a magnetic material or glycerin. Moreover, it is preferred that 12 to 125 wt. parts of the droplets are mixed with 100 wt. parts of the hydrophobic organic substance particles.

Filed: 1989-06-02
Abstract: PURPOSE:To prevent distortion in the phase of a reference clock by holding the output of a phase comparator circuit to compare the phase of a clock pit signal with the phase of the reference clock when the level of a clock pit reproducing waveform to be obtained from a track is more than a first prescribed value or less than a second prescribed value. CONSTITUTION:A first comparator 12 compares the level of the clock pit reproducing waveform to be obtained from the track with the first prescribed value and a second comparator 13 compares the level of the clock pit reproducing waveform to be obtained from the track with the second prescribed value. When the level of the clock pit reproducing waveform is more than the first prescribed value or less than the second prescribed value, the output of a phase comparator circuit 9a to compare the phase of the clock pit signal with the phase of a reference clock CK is held. Thus, even when the level of a clock pit detecting waveform from an optical disk 1 is widely changed rapidly near a clock pit, the frequency and phase of the reference clock CK are not distorted and information always is recorded and reproduced with high accuracy.

Filed: 1990-05-30
Abstract: PURPOSE:To eliminate the necessity of an Oldham's coupling and a bearing support so as to simplify the structure by carrying out oscillation of an oscillating scroll under electromagnetic action. CONSTITUTION:In a motor for a scroll compressor, four pole windings are formed on an external iron core 1 having a center O, and two pole windings are formed on an internal iron core 2 having a center O'. The frequency of a voltage applied to the external iron core 1 is set to be twice as large as that of a voltage applied to the internal iron core 2. In this arrangement, the phase of a power source for applying voltage to the external and internal iron cores 1, 2 are turned so that a formed magnetic field is small, and accordingly, the inner iron core 2 does not rotate about the center O' although is displaces in association with the rotation of the magnetic field. That is, it is possible to carry out eccentric oscillation. With this arrangement in which the oscillation of an oscillating scroll is carried out under magnetic action, the necessity of an Oldham's coupling and a bearing support can be eliminated, thereby it is possible to simplify the structure of the scroll compressor.

Title: Image forming device
Inventor: NISHIZAWA AKINORI
IPC: H04N1/00
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device which prevents the occurrence double order by using a toner order sheet. SOLUTION: When 'toner empty' is detected, an MPU 11 automatically issues a toner order sheet through a recording part 15. However, until the number of recorded sheets reaches a specific number of sheets (for example, 100 sheet) after the first detection of the 'toner empty', in other words, until the recording part 15 reaches the limit of recording, images are recorded by the recording part 15 as usual. Also, even in the case 'toner empty' is detected again, the re-issue of the toner order sheet is inhibited once the toner order sheet has been issued. Therefore, no more than one toner order sheet is issued. Accordingly, the occurrence of double order can securely be prevented.
