Title: Ion wind air purifier
Inventor: MATSUSHIRO TADASHI
IPC: B03C3/66
Filed: 1985-03-20
Abstract: PURPOSE:To suppress the vibration or resonance applied to an ionization electrode and to reduce noise, by reducing the ripple ratio to a specific value or less by the condenser inserted in a high voltage part. CONSTITUTION:The secondary voltage converted by a transformer 1 is rectified and boosted by a voltage doubler tube circuit constituted by the pi-connection of diodes 2-6 and condensers 7-11 and smoothed by a smoothing condenser 12 to generate DC high voltage. This DC high voltage is applied between an ionization electrode and the opposed electrode arranged in the leedward side of said electrode in opposed relation thereto to ionize the particles such as dust particles in air and the ionized particles are attracted to the opposed elec trode. At this time, by suppressing the ripple ratio of high voltage output to 1% or less, noise reduction is achieved and comfortable air purification can be performed in a non-rasping irritating noise manner.

Title: Voltage dividing circuit for measurement of high voltage
Inventor: MATSUBA HIRONORI
IPC: G01R15/06
Filed: 1980-04-28
Abstract: PURPOSE:To obtain a circuit having almost even frequency response characteristic over a wide range from DC to a high frequency as well as a high impedance, by deciding the resistance voltage dividing point as an output terminal for an output circuit of the coaxial cable. CONSTITUTION:The voltage dividing main circuit 4 consists of the voltage dividing capacitors 1 and 2 plus resistor 3. For the coaxial cable 5, the center conductor 5a and external conductor 5b are connected to the resistor 3 and the earth respectively. In the output circuit 8, a series circuit comprising the resistors 9 and 10 plus capacitor 7 is connected between the conductor 5a and the earth, and the voltage dividing point Q of resistors 9 and 10 each is connected to the output terminal. In this case, the value of resistor 3 is selected to the characteristic impedance of cable 5, and the value of resistors 9 and 10 are selected to (1-r)R and rR respectively. At the same time, such capacity value is set so that a wide response property is obtained for the step function of C1/C2 times as much as capacity value of capacitors 2 and 7 each to the step function of input.

Title: Magnet device
Inventor: IWAI MASAHARU
IPC: H01F7/02
Filed: 1992-02-07
Abstract: PURPOSE:To realize the weight reduction of magnet device by molding a specific conductive resin which is produced by diffusion-combining polyacetal or ABS resin with a conductive filler, in order to obtain a flange. CONSTITUTION:Flanges 3A and 3B are molded by using conductive resin in which polyacetal or ABS resin is diffusion-combined with a conductive filler and which has an electrical resistance of 10<8>OMEGA.cm or less. The electrical resistance shall be set to less than 10<8>OMEGA.cm because the conduction will become unstable and a developer be applied with ununiform electrical force, resulting in generating any void, etc., if the electrical resistance exceeds 10<8>OMEGA.cm. The polyacetal or ABS resin is adopted as a synthesized resin because there is especially less deterioration of mechanical strength when the conductive filler is combined. One half flange 3B is necessary to be fitted into a sleeve S after it is inserted into a magnet roll so that a magnet roll M is inserted into the sleeve S, so only one half flange 3A is used to be formed together with the sleeve S.

A negative pressure near a throttle valve 4 is introduced into the chamber 8, and the control valve 7 and the first control valve 12 are opened. As the result, a manifold negative pressure is introduced into a negative pressure chamber 16 of the second control valve 15 via chambers 22 and 13 to draw up a diaphragm 15'. Consequently, a negative pressure in a Venturi tube 20 is introduced into the chamber 8 via passages 19 and 6, increasing the opening degree of the control valve 7.

IPC: G06F13/36
Filed: 1986-03-14
Abstract: PURPOSE:To attain high speed data transfer by separating an internal data bus part connecting between specific function blocks requiring high speed data transfer from an internal data bus part unnecessary for the data transfer. CONSTITUTION:Bus switching circuits 7, 8 are arranged so that an internal data bus B connecting these circuits 7, 8 is set up as short as possible. The bus switching circuits 7, 8 are constituted of transfer gates for bi-directional transmission, and when a control line F is turned to '0', a data line X is separated from a data line Y, the status of the line X side exerts no influence upon the line Y side and the status of the line Y side also exerts no influence upon the line X side. Consequently, wiring capacity and wiring resistance of the X side can be also separated from that of the Y side.

Title: Rolling mill controller
Inventor: HASHIMOTO JUNYA
IPC: G05D3/12
Filed: 1995-03-16
Abstract: PURPOSE: To improve the control precision and lower the cost by enabling respective control means to output necessary correction quantities. CONSTITUTION: The control means 1-5 operate rolling reduction obauge quantities ΔSt1 -ΔStn per unit time on the basis of respective deviation inputs. A control selecting means 6 selects a specific quantity out of them and outputs it to a rolling reduction quantity adding integration device 8. In the device 8, an addition data integrating means 8A integrates the addition value of the data from the selecting means 6. This integrated value is sent as a final rolling reduction correction quantity ΔSt T to an actuator 9 for rolling reduction control through a limiter 8B. None of the control means 1-5 is provided with a limiter, so their arithmetic results needed for arithmetic operation are outputted to the selecting means 6 as they are.  When the selecting means 6 performs switching, for example, from a control means 1 to a control means 2, the output of the integration means 8A never becomes zero even if the output of the selecting means 6 becomes zero momentarily.

The solid printing pattern Ya is the pattern in which the toner is transferred on the whole area of the prescribed region on a paper sheet carrying belt 23. The positional accuracy and the printing density of the black color can be easily and correctly judged using a judging means. Correct judgment free from incorrect detection can be made because any flaws or pollution on the paper sheet carrying belt can be covered with the yellow solid printing pattern Ya.

IPC: G05F3/20
Filed: 1978-05-15
Abstract: PURPOSE:To always secure the optimum threshold voltage for the MOSFET by providing the following means: the application means to apply the bias potential to the semiconductor substrate; the means to detect the change of the bias potential; and the by-pass means to control the current amount via the detecting means respectively. CONSTITUTION:The circuit consists of the following component units: oscillator 11; driving circuit 12; coupling capacity 13; MOS diode Q11 and Q12; reference voltage generator circuit 21; circuit 23 which compares the reference voltage of node 22 with the threshold voltage of MOSFET element 14 and then generates the control voltage; and MOSFET element Q15 which give by-pass to the substrate bias voltage respectively. In such constitution, the output voltage of circuit 23 increases in case the leak current reduces and with the substrate bias voltage increased. Thus, the increment can be prevented for the substrate bias voltage. On the contrary, in case the leak current is large, the decrement of the substrate bias voltage is prevented to always secure a constant level for the threshold voltage of the MOSFET within the chip.

Filed: 1990-03-08
Abstract: PURPOSE:To slow down the movement of an actuator by providing a 2nd current source supplying a current smaller than that of a 1st current source for focus pulling in, and supplying a current of the 2nd current source to the actuator when a lens approaches a medium to some degrees or over. CONSTITUTION:When a current supplied from a 1st current source 8 and a lens approaches a medium to some degrees, a focus sum signal (a) and a focus error signal (c) are outputted from a head.

Since the current supply from the 2nd current source 9 is smaller than the current of the 1st current source 8, the movement of the actuator 2 slows down more than that by the current supply of the 1st current source 8 only.
