Title: Electric dust collecting apparatus
Inventor: ECHIZENYA SADAYOSHI
IPC: B03C3/51
Filed: 1981-11-19
Abstract: PURPOSE:To make it possible to collect high resistant dust in high efficiency without conditioning humidity, by respectively mounting power sources supplying half-wave AC voltages having different polarities and 180 deg. phase differences to discharge electrodes adjacent across a dust collecting electrode. CONSTITUTION:AC voltage to a power source 3 from an AC power source 5 is raised by a voltage controller 6 and a transformer 7 and, while subjected to half-wave rectification by a rectifier 8, applied to a discharge electrode 2A through protective resistance  R1 to generate corona discharge with positive polarity which is in turn flowed into a dust collecting electrode 1 made of a metal net. By positive polarity ion generated in this case, dust is charged to positive polarity to be collected by the electrode 1. On the other hand, AC voltage to a power source 4 from an AC power source 5 is raised by an automatic voltage controller 10 and a transformer 11 and, while subjected to half- wave rectification by a rectifier 13, applied to a discharge electrode 2B through protective resistance R2 to flow a corona discharge current with negative polarity into the electrode 1. Dust charged to negative polarity by said netative corona discharge is collected by the electrode 1. The dusts collected by the electrode 1 are mutually neutralized to reduce the charge accumulation of a piled layer and to prevent inverse ionization.

Title: Controller for electrophotographic copying machine
Inventor: KASAHARA SEITARO
IPC: G03B27/50
Filed: 1987-07-25
Abstract: PURPOSE:To control precisely a position with only one sensor by disposing an optically driving motor encoder on the driving motor of an optical system, counting optical encoder pulses, judging the position of said system and controlling it. CONSTITUTION:In the optical system 4 composed of a lens sending original images to an exposure part 5 and a mirror group, the optical system driving motor is equipped with the optically driving motor encoder. Since a distance by which the optical system moves per pulse of said encoder is constant, the position of the optical system is determined by counting the number of encoder pulses even if speed of the optical system is varied. A home position sensor is placed to serve as a reference position, and only said sensor detects the optical position. Thus one sensor alone can detect the moving position of the optical system and control it surely.

Abstract: PROBLEM TO BE SOLVED: To shorten the engine starting time in cold starting. SOLUTION: A valve driving mechanism 20 is provided with a structure capable of optionally changing the opening and closing timing of intake and exhaust valves 11, 12. A CPU 50a in an ECU 50 controls the operation of the valve driving mechanism 20 to variably adjust the opening and closing timing of the intake and exhaust valves 11, 12. In the period from the start of start-up of the engine 1 to the completion of warming up, the CPU 50a closes the exhaust valve 12 earlier than a TDC by the operation of the valve driving mechanism 20 on the basis of the engine operating state, and opens the intake valve 11 by the TDC or opens it later than the TDC. In this case, high- temperature burnt gas remains in a cylinder and is heat-converted by taking the increased amount of pumping loss as the increase of the cylinder gas temperature. Therefore, the temperature in the cylinder is raised.

IPC: G01C1/00
Filed: 1987-07-27
Abstract: PURPOSE:To enable the highly precise measurement of an incident angle of beam on a substance, by a method wherein a diffraction grating is provided on the substance, one of diffracted beams of an incident beam caused by the diffraction grating is reflected, the reflected beam and at least one diffracted beam are made to interface with each other, and the beam intensity of a composite beam thus formed is measured. CONSTITUTION:A reflected beam R is obtained by making a diffracted beam D2 reflected by a reflector 2, and it is made to advance in the same direction with that of another diffracted beam D1 so that the beams D1 and R are made to interfere with each other. The phase of the beam R is delayed by the length of its optical path because of its going through the reflector 2, and a phase delay DELTApsi thereof is determined by a distance to the reflector 2 and a diffraction angle theta. The angle thetais varied in accordance with variation in an incident angle psi, and the incident angle psican be measured by a method wherein the beams R and D1 are made to interfere with each other and the phase delay DELTApsi is introduced into a detector 3 and measured from the variation in the intensity of a composite beam U of said lights. Accordingly, since the diffracted beam is used, the incident angle can be measured with high precision without affecting virtually a beam transmitted directly through a substance 1 and a beam reflected directly on the substance 1.

Filed: 1986-08-08
Abstract: PURPOSE:To make it possible to use an amplifier even if the internal resistance of an input signal generator is high, by connecting an emitter follower input stage consisting of an n-stage Darlington transistor TR ((n) is equal to or larger than two and is an integer) to the base of an amplifying TR and connecting a series circuit of (n-1)-number of diodes to the emitter.

A diode series circuit 15 where (n-1)-number of diodes are connected in series is connected to the emitter of the amplifying TR 11. The amplification factor hFEP is very high because the number of stages of the Darlington TR is equal to or larger than 2, and a current I0 flowing out from the base of the Darlington TR 12 can be reduced, and therefore, the voltage drop due to the internal resistance is small and the circuit is operated well even if the internal resistance of an input signal generator 19 is high.

Abstract: PROBLEM TO BE SOLVED: To eliminate nuisance in the payment procedure or the like of a software rental fee due to the version up of software by sending information related to the updating of software to a prescribed agency when the software in another equipment connected to a digital transmission line is updated. SOLUTION: A digital VTR 20 detects that the header part of input data is in a prescribed format, discriminates that the input data are its own updating data and executes the version up of its own program. After completing the updating of function information in a non-volatile memory 28, the VTR 20 sends the completion of version-up to a STB 10 through IEEE 1394. The STB 10 discriminates the function information inputted from the VTR 20, rewrites data in a table stored in a non-volatile memory 17 and informs an external charging agency (a charging center, a broadcasting station, etc.), of the version-up of the VTR 20 through a MODEM 19.
