Title: Image-forming device
Inventor: SATAKE KENICHI
IPC: G03G15/16
Filed: 1999-09-20
Abstract: PROBLEM TO BE SOLVED: To provide an image-forming device, capable of performing satisfactory transfer which is not influenced by the change in environment, such as temperature and humidity and the change of transfer paper size by easy control based on few parameters. SOLUTION: First, transfer paper size is detected by a transfer paper size detection part 3. A control part 1 sets an appropriate current I0 corresponding to the transfer paper size based on the corresponding information of the transfer paper size to the appropriate current stored in advance, and performs constant- current control. When the leading edge of transfer paper reaches a transfer part 59, a current I1 flowing to a pre-transfer guide 58 through transfer paper P from a transfer roller 2 is detected by a current detection part 60, while the transfer part 59 is positioned in a non-image area at the leading edge part of the transfer paper P.  The control part 1 calculates a correction current IX using IX=I02/ (I0-I1), based on the appropriate current I0 and the current I1 and performs transfer processing, while performing constant-current control of the roller 2 at the correction current IX.

IPC: B65D1/00
Filed: 1988-10-21
Abstract: PURPOSE:To enhance impact resistance, in the cut surface parallel to the circumferential direction of the side wall of a molded container and vertical to the surface of said side wall, by setting the double refractivity shown by the difference between the refractivity in the circumferential direction and the refractivity in a thickness direction to a specific value. CONSTITUTION:In preparing a deep draw molded container from a sheet composed of polyethylene terephthalate by a plug-assist method, the deep draw molded container is obtained by setting the diameter or width of a plug to 80% or less of the inner diameter of a mold and the double refractivity between the refractivity n1 in a circumferential direction and the refractivity n2 in a thickness direction is set at least to 0.05 in this container. Therefore, plug temp. is set to a temp. range from the glass transition temp. Tg of the sheet to Tg+90 deg.C. This deep draw molded container is obtained for the first time by a plug-assist method. In a conventional deep drawing molded container, the side wall of the container is molecularly oriented only in a longitudinal direction. Contrarily, since this container takes a biaxial orientation structure wherein a molecular chain is also oriented in the circumferential direction, no longitudinal cracking is generated and impact resistance is excellent.

Title: Multirate fsk signal switching circuit
Inventor: TAKADA MASATOSHI
IPC: H04B1/04
Filed: 1994-10-06
Abstract: PURPOSE: To suppress the spread of a band by outputting a signal from a first or second output terminal while switching it after the signal is suppressed for fixed time set in advance by a switching circuit each time the transmission rate of an input signal is switched. CONSTITUTION: Each time the transmission rate is switched by a select signal, the input signal is alternately switched in the order of a first LPF 2, second LPF 3 and first LPF 2. Namely, a guard space is set just for a prescribed time length just after switching and the input to the filter is suppressed. In this case, a signal for one symbol is erased even at any transmission rate and the guard space is secured. The waveforms of the outputs of the LPF 2 and LPF 3 passed through the respective filters are synthesized by a synthesizing circuit 4 and outputted as an output signal. Thus, since the input signal is suppressed for fixed time just after switching, the expansion of the waveform is suppressed and spectrum is not spread after FSK modulation.

Filed: 1988-10-22
Abstract: PURPOSE:To achieve a small temperature coefficient for saturation magnetization (4piMs) by substituting a portion of the composition of Gd-Y-Ca-In-V series magnetic garnet with a suitable of Al and Mn. CONSTITUTION:A material denoted by a composition formula GdxY3-x-2zCa2zFe5-u-v-y-zInyVzAluMnvO12 and having composition satisfying 1.0<=x<=3.0, 0<y<=0.5, 0<z<=0.5, 0<u<=1.0, 0<v<=0.1.

In this case, the Al amount u and the Mn amount v are determined to be 0<u<=1.0, 0<v<=0.1 based on the experiment. Thus, the temperature coefficient for saturation magnetization (4piMs) is suppressed to have very small value less than 0.08%, and the dielectric loss (tandelta) is reduced to about 2X10<-4>.
