Title: Biasing device for development in electrostatic recorder
Inventor: NAGAHIRA JIYOUJI
IPC: G03G15/06
Filed: 1982-04-05
Abstract: PURPOSE:To obtain a stable biasing voltage with less regulation, by using the sine wave voltage obtained from a sine wave oscillator and the AC voltage increased with a boosting transformer as the biasing voltage and making the output of an amplifier circuit constant with an automatic gain control circuit. CONSTITUTION:A sine wave oscillation circuit 9a or 9b is selected by a switch 16a, and oscillates a sine wave of a stable frequency. The sine wave is amplified with an amplifier 10 which is controlled of gain with an automatic gain control circuit 17; thereafter, the sine wave is increased in voltage with a boosting transformer 11 and is applied to a developing sleeve 8. Said voltage and the DC bias voltage from a DC-DC inverter 14a or 14b are applied superposedly on the sleeve 8 and jumping developing is accomplished. When the sleeve is not biased with the AC in this stage, the picture image having high contrast is formed and when the sleeve is biased, the gradation is reproduced well. When the DC bias is increased, the developing of the white ground part and low density of the original is suppressed and the developed image is obtained with good reproducibility of the gradation and with less photographic fogs.

Abstract: PURPOSE:To suppress a bird's beak and to attain high integration of a semiconductor element by a method wherein, after an oxidation-resistant mask is formed on a semiconductor substrate, a semiconductor layer is formed on the side wall portion of this oxidation-resistant mask, and thereafter the semiconductor substrate is oxidized selectively. CONSTITUTION:After an oxidation-resistant mask 14 is formed on a semiconductor substrate 1, a semiconductor layer 19 is formed on the side wall portion of this oxidation-resistant mask 1, and thereafter the semiconductor substrate 1 is oxidized selectively.

Consequently, the bird's beak 18 is so suppressed as to reduce an area occupied by the selectively-oxidized films 2 on the semiconductor substrate 1. Thereby the region of the semiconductor substrate can be increased, and high integration of a semiconductor element can be attained.

Abstract: PURPOSE:To provide an apparatus which decides whether an AD converter is good or not while the AD converter is held set in the apparatus by inputting the signal from a reference signal generating means and deciding the AD conversion signal of that time. CONSTITUTION:Stationary DC constant voltage power sources V1, V2 are kept at V1 V2 and are respectively connected to the input ports CH1, CH2 of a multiplexer CT11. If the input conversion range of an AD converter CT4 is assumed to be + or -10V, the above are set at V1=-5V, V2=5V, and if the conversion accuracy of the AD converter CT4 is assumed to be 8 bits, the conversion value of V1 is specified as 3F (sexadecimal) and the conversion value of V2 as BF (sexadecimal). Hence, in order to discover the defect of CT11, CT4, V1, V2 are successively AD- converted, and their equality to the values 3F, BF having beforehand been set in the ROM or RAM of a microcomputer CT3 within a certain permissible error is judged with the microcomputer CT3. This permissible error is determined by the conversion error of the AD converter CT4 and the errors of the set voltages of V1, V2. It is judged that CT11 and CT4 are normal only when both of the AD conversion values of V1, V2 coincide with the set values.
