Title: Dc-dc switching power supply device
Inventor: MERA HIROMITSU
IPC: H02M3/28
Filed: 1994-05-23
Abstract: PURPOSE:To eliminate the mutual influence (interference) of output when a plurality of switching power supply circuits are provided and to reduce the circuit scale. CONSTITUTION:A common single PWM control circuit 10 is provided for two switching power supply circuits generating outputs(a) and (b). Two switching elements 2a and 2b are simultaneously turned on and are turned off individually according to each output voltage level. Therefore, the expansion of the power supply circuit does not increase the scale due to the single PWM control circuit. Also, all switching elements are fumed on simultaneously so that the on-pulse is synchronized, thus preventing the output from interfering one another.

Title: Method for controlling temperature of billet in direct rolling
Inventor: ENDOU TOSHIO
IPC: B22D11/12
Filed: 1984-05-30
Abstract: PURPOSE:To improve the quality of a product by estimating the billet temp. at the inlet of a rolling mill from the actually measured value of the change in the load of a rolling stand and controlling the flow rate of cooling water in accordance with the estimated temp. CONSTITUTION:An arithmetic unit 5 is inputted with the rolling load 50 of a rolling mill 4 and calculates the command value to be outputted to a cooler 7.

Title: Amorphous cut core
Inventor: SHIGETA MASAO
IPC: H01F27/24
Filed: 1983-06-16
Abstract: PURPOSE:To reduce the iron loss and the deterioration of permeability of the titled core by a method wherein the thickness of a thin band on the cut end face of cut material of the wound-around material, whereon an amorpeous magnetic alloy thin band is wound, is formed almost equal to that of the thin band. CONSTITUTION:After the thin band 2 of an amorphous magnetic alloy has been wound around a bobbin, said thin band 2 is fixed by peforming a pressure-welding at the point located in the vicinity of a cut part, and the cut material of C- shape, U-shape, I-shape and the like are formed by cutting the above-mentioned material. Then, a grinding work is performed on the cut end face of the cut material 1 in the grinding process to be performed after cutting in such a manner that the cut end face will be brought almost in parallel with the lateral direction. Through these procedures, the eddy current loss due to the burrs or saggings of the thin belt 2 on the cut end face is markedly reduced, and the iron loss is also reduced, thereby enabling to improve the permeability of the title core.

Title: Image forming device
Inventor: SATO NORIBUMI
IPC: G03G15/02
Filed: 1995-05-02
Abstract: PURPOSE: To suppress the occurrence of density unevenness while keeping such constitution that attachment/detachment is easy by constituting so that developing density is controlled by detecting the displacement of an image forming unit. CONSTITUTION: The vibration or the fluctuation component of the image forming unit 1 is detected by a vibration detection means 7 and the vibration or the fluctuation thereof is transmitted to a density control means 8 as an analog vibration signal. Then, since the moving speed of the unit 1 in a direction shown by an arrow B is added to the surface moving speed of a photoreceptor 9 in a direction shown by an arrow A when the unit 1 is displaced downward, the image density is lowered as the result. In such a case, since an output transmitted to the power source circuit of an electrostatic charge roll by the detection means 7 becomes large, the DC level of a chopping wave signal rises and the pulse width of a switching pulse becomes narrow. Besides, an output high voltage is lowered.  Therefore, the electrostatic charge potential of a photoreceptor 9 is lowered and potential difference between the electrostatic charge potential and a developing bias voltage becomes large. Besides the developing density is made high. Thus, the image density is maintained to be constant as a whole.
