Title: Method and apparatus for beam diagnosis
Inventor: TANAKA HIROBUMI
IPC: G01T1/29
Filed: 1992-08-25
Abstract: PURPOSE:To allow direct observation of ion trapping by disposing a Cherenkov monitor on the extension of a linear part on the orbital plane on which a charged particle rotates thereby measuring bremsstrahlung gamma-ray. CONSTITUTION:Electrons are deflected by means of a deflecting electromagnet 12, converged by means of a quadrupole magnet 13 and rotate in a vacuum chamber 11. The electron emits SR light in the electromagnet 12 to lose its energy which is eventually compensated for by a high frequency electric field in an RF cavity 16 and stored stably. Orbital shift of beam is corrected by means of a steering electromagnet 15. A Cherenkov monitor 7 is disposed on the extension of a linear part on the orbital plane of the beam on which the electron circulates. Synchrotron radiation does not take place in that direction but only bremsstrahlung gamma-ray is radiated and the quantity thereof is proportional to the quantity of ion trapped by the electron. Consequently, ion trapping quantity over the entire linear part can be determined based on the measurement of gamma-ray. Signals obtained through the Cherenkov monitor 7 are fed through a signal processing circuit to a contradiction computor 19 where various data processings are performed.

Title: Power feeding circuit
Inventor: TAKATO KENJI
IPC: H04M19/00
Filed: 1991-09-05
Abstract: PURPOSE:To obtain a feeding circuit stable in impedance characteristics or the like in a subscriber's circuit in a digital exchange by detecting voltage between a TIP line and ground potential and voltage between a RING line and VBB potential and feeding back the sum of current values corresponding to the detected voltage values. CONSTITUTION:Resistors Rb in respective voltage detecting circuits 2, 3 respectively detect voltage VTG between the TIP line and the ground potential and voltage between the RING line and the VBB potential and mirror circuits M1, M2 generate currents corresponding to the detected voltages. These currents are added by a current adder 7 and the added current is inputted to a current limiting circuit 8. The circuit 8 limits the current of a transistor(TR) Q2. The current of a TR Q4 becomes the inverted current component of the TR Q2 and allowed to flow into resistors Re through mirror circuits M5, M6. Voltages generated in the resistors Re cause the output of feeding currents proportional to the resistance values of the resistors Re from bidirectional current circuits 4, 5 through buffer amplifiers 20, 21. Thus various necessary characteristics can be obtained.

Filed: 1989-09-04
Abstract: PURPOSE:To improve the precision of the toner concn. control of a detecting pattern regardless of a potential control by detecting the surface potential of the detection pattern by means of a surface electrometer and controlling a developing bias so as to obtain a constant developing potential. CONSTITUTION:When a P sensor 12 is checked, the electrostatic latent image of the detection pattern is formed and its surface potential is measured by the surface electrometer 9. Then, the level of an image density set by an user is checked and a required developing bias (a correcting bias) is calculated to be applied at its density level. When the above-mentioned correcting value reaches a development starting voltage (potential), the toner is switched to a small and constant replenishment. When the above-mentioned value does not reach the development starting voltage, the correcting bias is applied to a developing sleeve, the toner image of the detection pattern is formed, and its patterns density is measured by the P sensor 12. With a result, when the density is at low level, the toner is replenished, and when the density is at high level, the replenishment of the toner is stopped.
