Title: Power amplifier
Inventor: KOIDE HIDEYUKI
IPC: H03F1/30
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To provide a power amplifier which excels in both the frequency and temperature characteristics by controlling the attenuation of a variable attenuator by means of a power monitor circuit and an output control circuit to keep the constant frequency characteristic and compensating the temperature characteristic of the power monitor circuit by means of a temperature monitor circuit. SOLUTION: A power monitor circuit 11 transmits a signal corresponding to the electric power that is outputted from an electric power synthesizing circuit 4 to an output control circuit 8. The circuit 8 controls the attenuation of a variable attenuator 6 so as to always keep the output of the circuit 11 at a fixed level. If this amplifier uses a semiconductor such as a diode to the circuit 11, the output value of the circuit 11 varies in response to the temperature change, even if the output voltage is constant. Thereby, the temperature of the circuit 11 is measured by a temperature monitor circuit 7, and the output value of the circuit 8 is corrected based on the output value of the circuit 7. As a result, the voltage that is outputted from an output terminal 5 is kept at a constant level.

Therefore, a memory phenomenon due to the residual toner at the time of electrostatic discharging and exposure can be precluded. Further, both the brushes 135a and 135b are formed of soft materials, so the photosensitive body surface is never flawed.

Title: Low hydrogen covered electrode
Inventor: UMEKI MASAO
IPC: B23K35/365
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To obtain the covered electrode capable of preventing coating flux from falling off due to impact at transportation and at falling by specifying a component of coated flux. SOLUTION: Coated flux contains each of calcium carbonate, fluorite, ferrous silicon, metal manganese, sepiolite in a specified range weight %, further, an arc stabilizing agent, slag forming agent and binder. Sepiolite among the components is effective to improve binding force of the coated flux, that is, and has good dispersibility in water glass, when adding in the coated flux, its fibers are complicately entwined each other at mixing in water glass, as a result, sepiolite has function to improve thickening property of the coated flux. Further, at drying in producing the electrode, sepiolite is solidified by itself. Accordingly, bindability of the coated flux is excellent due to these thickening and solidity, it prevent the coated flux from falling off.  However, in the case of excess use, sepiolite incurs deterioration of welding workability and there evidently exists an appropriate range.
