IPC: G03G9/08
Filed: 1995-02-27
Abstract: PURPOSE: To decrease variation in the distribution of grain size among batches, to render a classifying process unnecessary, and to obtain a toner having sharp distribution of grain size at a high production yield by granulating the toner while monitoring the distribution of grain size with an in-line grain size distribution measuring instrument. CONSTITUTION: In the granulating process of a toner, the distribution of grain size is monitored with an in-line grain size distribution measuring instrument, and when desired distribution of grain size is obtd., the granulating process is stopped. Namely, in this case, an in-line grain size distribution measuring instrument which is generally well-known as an in-line instrument attached to a polymn. reaction tank or the like to monitor the distribution of grain size of resin or liquid drops is used for the production of a toner for which severe control of the distribution of grain size is required. As for the in-line grain size distribution measuring instrument to be used, any instrument which can monitor the distribution of grain size by in-line method can be used, and an instrument using reflective laser scanning method is preferably used.

Title: Ultrasonic motor and steering device
Inventor: ISHINO YUKIHIDE
IPC: B62D1/18
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To suppress the change in the rotary characteristics of a rotor and the backlash of a rotary shaft, by equipping an axial energization member for energizing the rotary shaft in the same direction as a direction where the rotary shaft is energized by the energization force of a press energization member, and absorbing a load that is applied in a direction being opposite to the rotary shaft. SOLUTION: An accommodation recessed part 21a that is formed at a rotary shaft 21 accommodates an axial energization member 25 consisting of a coil spring 22, a collar 23, and a thrust chip 24, and the coil spring 22 performs energization in the same direction as a Belleville spring 14 energizes the rotary shaft 21. Therefore, when a load is applied to a direction that is opposite to the energization direction, the coil spring 22 nearly absorbs up to 15 kgf load, thus suppressing the change in the rotary characteristics of a rotor 13. Also, since the load being applied to the rotary shaft 21 increases, the frequency for generating the backlash radically decreases, thus suppressing the backlash of the rotary shaft 21.

Title: Manufacture of low loss oxide magnetic material
Inventor: NAKANO KENICHI
IPC: H01F1/36
Filed: 1986-03-20
Abstract: PURPOSE:To make small the crystal gain size, enlarge the specific resistance and improve frequency characteristic of core loss by mixing the raw materials mainly consisting of Fe2O3 and MnO, ZnO having the primary gain size in the particular range of size in the Mn-Zn system ferrite magnetic material and a small amount of SiO2 and CaO and then sintering them after granulation and press molding. CONSTITUTION:The core loss PB is defined as indicated in the figure depending on the average grain size of Fe2O2O3 and residue SO3 and the grain size of raw material Fe2O3 is in the range of 0.08-0.15mum and the core loss PB becomes as low as within 500kW/m<2> with the content of SO3 of 0.2-0.3wt%. In case the granularity of Fe2O3 raw material is small, the crystal becomes large by the sintering and if granularity is too large, density is lowered. In any case, core loss becomes large. Therefore, it is desirable that granularity is set to 0.08 to 0.15Xm. Moreover, content of SO3 in Fe2O3 is excessive, it interferes the sintering reaction, but if it is too short, it gives adverse effect on the reaction. In case a preliminary sintering is not carried out, it gives large influence and it is no longer possible to improve core loss.
