Title: Differential amplifier circuit
Inventor: YAMAMORI MANABU
IPC: H03F3/45
Filed: 1992-01-31
Abstract: PURPOSE:To make the improvement of a gain compatible with the improvement of stability of an operation by connecting directly the base of a differential pair transistor(TR) to an output terminal and providing a specific potential correction circuit to the amplifier circuit. CONSTITUTION:Since a resistor R7 is connected to the base of a transistor(TR) Q4 of a bias circuit 2C, the base potential is lower than the base potential of a TR Q3 of the bias circuit 2A and then an emitter potential is low attended therewith. Thus, a potential (node NB) at an output terminal, that is, the base bias potential of a differential pair TR Q2 is lower than a potential at the output terminal (node NA) of the bias circuit 2A, Thus, the potential at the output terminal (node NB), that is, the base bias potential of the differential pair TR Q2 is lower than the potential at the output terminal (node NA) of the bias circuit 2A. On the other hand, a potential lower by a voltage drop in a resistor R3 than the potential at the (node NA) is given to the base of the differential pair TR Q1. Thus, the base potential of the differential pair TRs Q1, Q2 is made equal to each other by setting the resistance of the resistor R7 properly. Thus, the input impedance of the differential amplifier circuit is decreased to increase the conductance, thereby increasing the gain.

Title: Display device for extension quantity of anchor chain
Inventor: SASAKI OSAMU
IPC: G01B21/06
Filed: 1987-01-28
Abstract: PURPOSE:To extend an anchor chain and stop its winding automatically without depending upon visual counting by detecting the rotating direction of a chain wheel by using a transmission segment and a sensing switch. CONSTITUTION:The transmission segment 5 is fitted to the chain wheel 3 and a proximity switch 6 is set opposite it. A pulse train from the proximity switch 6 is inputted to a counter part 7 consisting principally of a counter and the counter part 7 displays the extension length and the number of connections which are measured on a display part 8. This numeric value is set in a register in a warning and control operation setting part 13 and a comparator generates a warning and control output when the set value is reached. In general, an operator, etc., operates a brake in response to the numeric value or warning tone of the display part 8. Further, the shape of the transmission segment is made not equal in pattern between forward rotation and back ward rotation and a coincidence circuit stored previously with it discriminates the rewinding. Consequently, the extension of the anchor chain and the winding stop are performed automatically without depending upon visual counting.

Title: Electrophotographic device
Inventor: MIYAGAWA NOBUHIRO
IPC: G03G15/02
Filed: 1986-01-30
Abstract: PURPOSE:To prevent the surface of an amorphous silicon photoconductor from being deteriorated and to improve its brush resistance by employing a non-corona type electrostatic charging electrode contact system for all electrostatic charging mechanisms and using a conductive rubber blade for electrostatic charging as a main electrostatic charging mechanism. CONSTITUTION:The conductive rubber blade 15 has a tip part 16 which is pressed against the surface of a drum photoconductor layer 2 and the other end part is connected to a power source 18 for main electrostatic charging by a connection 17. A constant voltage based upon the conductive substrate 1 of a photosensitive body is applied to the tip 16 of the conductive rubber blade 15 for electrostatic charging and the blade tip 16 and photoconductor layer 2 move relatively to supply the electrostatic charge of the constant voltage to the surface of the photoconductor layer 2 uniformly. This device transfers a toner image to transfer paper 14 based on a non- corona system. The non-corona type electrostatic charging electrode contact system is employed for all electrostatic charging mechanisms of the electrophotographic device and then none of discharge products such as ozone and nitrogen oxide is generated, so there is neither the surface deterioration of the photosensitive layer nor the formation of a hydrophilic surface and the brush resistance of the photosensitive body is improved.

IPC: C21C7/072
Filed: 1979-02-19
Abstract: PURPOSE: To smelt without increasing carbon content in molten metal in smelting of low carbon molten metal using a ladel type smelting furnace by a method wherein hollow graphite electrode arc discharge is used to heat molten metal, and innert gas is blown into molten metal from hollow holes of the electrodes.  
     CONSTITUTION: A ladle type smelting furnace 1 is covered with lid 2 and graphite electrodes 6 having hollow holes 7 are suspended from the lid 2 holes in the furnace. The furnace is charged with molten metal 3 and reducing molten slag 4. Innert gas such as Ar is introduced through porous plug 10 at the bottom to sufficiently agitate molten metal 3 and molten slag 4. The tip of the electrodes 6 are separated from the molten slag 4 more than 4cm, and arc is produced to heat and to conduct current. At the same time, innert gas such as Ar is charged from the hollow holes 7 of the electrodes 6 at a rate of 25m/s or more in standard conversion value. Thus, smelting operation of desulfurization and degassing is performed without increasing carbon content of molten metal 3.

Title: Measuring method for distortion of deflection
Inventor: TAKEMURA HITOSHI
IPC: G01T1/29
Filed: 1980-02-15
Abstract: PURPOSE:To correct distortion of a beam deflection precisely by measuring the quantity of deflecting distortion of an electron beam in some order and in its reverse order and then by removing the extent of drift. CONSTITUTION:The extent of the drift of a beam is expressed by a linear function of time. Therefore, the extent of the drift at points A, B...H, and I within the range of beam deflection is expressed by straight line Q1 and that in the reverse order by straight line Q2; and the mean value at each point is constant extent S0 of the drift. When point E among those points is considered to be on the optical axis, the quantity of deflection distortion at point E can be considered to be nearly zero. Therefore, drift extent S0 can be detected by measuring the deflection distortion at E. Consequently, the deflection distortion is found at points A, B...H, and I and then the deflection distortion is found again in the reverse order to find the mean value at each point. Next, the mean value at point E is subtracted from the said mean value, so that the pure deflecting distortion quantity having the drift extent removed at all points is obtained.

Title: Voltage comparator
Inventor: KUSUMOTO KEIICHI
IPC: H03M1/08
Filed: 1992-02-03
Abstract: PURPOSE:To relax voltage fluctuation caused by field through during a hold period, to accelerate change speed for the voltage fluctuation of an output, to improve accuracy and to obtain a high converted frequency by hardly being affected by substrate noise and noise transmitted from a reference voltage. CONSTITUTION:When switches SW1, SW3 and SW4 are turned on, analog input signals are sampled. When the switches SW1, SW3 and SW4 are changed into the OFF state, analog input signal voltages are held. Switches SW5 and SW6 are turned on later after starting the hold period, and turned off earlier than the end of the hold period. During the hold period, an inverter 4 suppresses voltage fluctuation caused by charges injected by field through. A switch SW2 is turned on, and switches SW5 and SW7 are turned on later after starting a comparative period and turned off before the end of the comparative period. The inverter 4 loads positive feedback to an inverter 3 so as to be immune to noise.

Abstract: PURPOSE:To surely transmit the data among 3>= microcomputers with use of a smell number of transmission lines. CONSTITUTION:The microcomputers U1-U3 are circularly cascaded via the transmission lines L1-L3 and therefore the data can be transmitted in the prescribed direction only. For instance, the data can be transferred directly to the U3 tram the U2 vie the L2. Then the date can be transmitted to the U2 from the U3 via the L3 and to the U2 from the U1 via the L1 respectively. Therefore the data are transmitted via the L3, a bypass line L51, and the L1 when the U1 has the runaway. In such a constitution, a data transmission line is secured between the normal U2 and U3 despite the abnormality of the U1.
