Title: Developing machine for electrophotographic device
Inventor: DOI KOJI
IPC: G03G15/08
Filed: 1995-01-20
Abstract: PURPOSE: To always realize the stable transportation of developer by eliminating cloggings due to the collision and the compression of developer in between developing rolls even in the case a center feeding system is adopted in the developer transportation of an electrophotographic device. CONSTITUTION: The flow of developer 5 is divided into two flows by interposing a guiding member 4 in between a first and a second developing rolls 2, 3. The relationship of (θ2/θ1)<0.4 is made to be established in between angles θ1 in between respective magnetic poles of developer receiving poles 7 plurally arranged in the peripheral direction of the developing roll 3 and the angle θ2 formed by a first receiving pole 7-1 of the side of the roll 3 with respect to the receiving pole 6-1 of the developer roll 2 among receiving poles 7 and the narrowest gap position in between the second developing roll 3 and the guiding member 4. An antipole 7-0 generated in the side of the opposite direction to that of the roll revolution based on the receiving pole 7-1 is set to a magnetic force equal to or smaller than 0.01T (Tesla).  Thus, the collision and the cloggings of developer in the vicinity of the guiding member 4 are made small.

IPC: G01N21/88
Filed: 1983-01-20
Abstract: PURPOSE:To inspect diffraction efficiency and convergency at the same time by measuring primary diffracted light from all holograms on a disk irradiated with laser light, inspecting the diffraction efficiency, and inspecting a defect on the basis of whether a diffraction image due to the defect is generated or not and its size.

Title: Variable reference voltage type comparator
Inventor: KUROKI YOSHINORI
IPC: H03K5/08
Filed: 1981-01-23
Abstract: PURPOSE:To prevent oscillation by performing switching operation fast by composing the 2nd switch of an equivalent PNPN switch circuit in a comparator which has hysteresis characteristics through the switching of the 1st and 2nd switches. CONSTITUTION:When an input voltage E is higher than a reference voltage Vt1 obtained through the voltage division of resistances R11 and R12, a transistor TR11 turns on, a TR12 turns off, and a TR17, therefore, turns off, so that any voltage is developed at an output terminal. When the voltage drops below the voltage Vt1, the TR11 turns off and the TR12 also turns off. This inversion is performed rapidly because a TR13 constituting an equivalent PNPN switch circuit also operates in cooperation, and a resistance R13 is inserted in parallel to the R11, so that the reference voltage applied to the base of the TR12 rises up  to a Vt2. When the voltage E rises above the voltage Vt2, the TR11 turns on,  and the TRs 12, 13 and 17 turn off to make the reference voltage drop down to  the Vt1, ceasing the output voltage. The switching of the reference voltage is  performed simultaneously with the on-off operation of the TR12, so oscillation never occurs.

Title: Portable type medical device
Inventor: ONODA MASAHIRO
IPC: A61B5/00
Filed: 1992-01-22
Abstract: PURPOSE:To provide a portable type medical device which has a data transfer means by magnetic coupling and has a safety circuit preventing dangers of electric circuit destruction and human body electric shock, even at the time an external strong magnetic field induces high voltage in a built-in coil. CONSTITUTION:In the magnetic communication part of the portable type medical device, external strong magnetic field induces high voltage in a coil 53 for magnetic communication. When the high voltage exceeds the prescribed voltage of a voltage limiting element 52, the resistance value of the element 52 lowers. This flows an excessive current through a fuse element 51 and the element 51 cuts off the line because of the excessive current. The high voltage generated between botheuds (between a-b) of the coil 53 is thus prevented from coming out between output terminals (between c-d).
