Title: Detecting circuit for toner density
Inventor: YAMADA HIROSHI
IPC: G03G15/08
Filed: 1980-12-29
Abstract: PURPOSE:To control toner density with high sensitivity and high precision without the influence of environmental variation, by detecting a phase difference between a power voltage and a voltage based upon variation in reactance and by supplying toner in the amount which corresponds to the difference. CONSTITUTION:When voltage of an AC power source 1, a detection coil 2, and resistances 3, 4 and 5 are V0, VL, V3, V4 and V5 and a deviation voltage between intermediate points P and Q is VD, VD=V4+V5=VL+V3, and VD=V3- V5; when V4=V5, VD=V3-1/2V0. Further, the voltages VL and V3 are 90 deg. out of phase, and the vector of the voltage V3 moves at a point Q on a circumference having a diameter equivalent to the voltage V0. The vector of the VD, on the other hand, is expressed by PQ. When the conductance of a detection coil varies, the Q changes into a Q' and a control voltage proportional to variation theta in phase difference, thereby supplying toner in accordance with the voltage.

Title: Manufacture of diode with short switching time
Inventor: OOHIRA KENYA
IPC: H01L29/861
Filed: 1980-12-29
Abstract: PURPOSE:To obtain the required switching time accurately without increasing the leakage current of the reverse direction by a method wherein after a diode element is irradiated by gamma-ray it is treated by heat under the specific temperature range. CONSTITUTION:A P-N junction is formed on a Si-board into which life-time killer is not introduced. A plurality of such boards are exminaled and subdivided into sqaares of required dimensions. The pillar-shape laminate; to both ends  of which lead wires are connected, is sealed by molding and put close to the  gamma-ray source to be irradiated by gamma-ray of 1-5X10<8>R. Then the irradiated diode  is annealed at 100-200 deg.C. The most of the leakage current disappears by this  thermal processing and recovers to the opproximately same-valve as before  irradiation. Such recovery phenomena is caused by the recovery of the low injection level life time and the high injection level life time is not recovered by the thermal pro cessing under above temperature, so that the switching time is not  increased.

Title: Screen for image projection
Inventor: KITATORA HIROTO
IPC: G03B21/56
Filed: 1990-07-12
Abstract: PURPOSE:To install the screen in a place where there is no wall surface behind by equipping a support rod, provided below a screen part, with plural rod-shaped weights. CONSTITUTION:This screen 1 for image projection when not used is all stored and fixed in a screen part storage case 2 fixed to the ceiling. When the rod- shaped weights 5 are hooked on metallic fixtures 6, the screen is unwound by gravitation until the weights balance with the elastic force of a winding device 3, and stops. The rod-shaped weights which are long and heavy enough are used and then hooked on the weight hook metallic fixtures 6 extremely easily. Thus, the screen for image projection becomes ready to use, and this state is fixed by the balancing between the elastic force of the winding device and the weights, so no metallic stopper for fixation is required. Further, when this screen 1 is in use, the downward force of the rod-shaped weights 5 and the upward elastic force of the winding device 3 operate on the screen 1, so the swing of the screen 1 which is caused by convection of air, etc., is extremely small.
