Title: Control method for developer toner concentration
Inventor: ODAGIRI JUNICHI
IPC: G03G15/08
Filed: 1986-01-14
Abstract: PURPOSE:To suitably control a toner concentration even in plural reference concentrations by impressing a reference voltage in a voltage comparing means from the external part and changing the reference toner concentration of a developer. CONSTITUTION:When the type of a developer is changed and the necessity to change other toner concentration occurs, a variable resistance Rv is adjusted and the reference voltage is changed. Namely, when the toner concentration is controlled based on T1 and the variable resistance Rv is large, the reference voltage of a voltage comparing circuit 13 comes to be high, comes to be the value shown by E1 and the toner concentration can be set to the T1 of the low level. When the toner concentration is to be increased to T2, reversely, the variable resistance Rv is small and the reference voltage may be lowered to E2. The relation between the toner concentration changing width and the reference voltage changing width can be freely selected by considering the characteristic of a detecting circuit, the character of the developer and so on.

Title: Phase-locked loop initialized by calibrated oscillator control value
Inventor: JIEEMUSU ROBAATO BOOTORINI
IPC: H03L3/00
Filed: 1995-01-20
Abstract: PURPOSE: To provide an inexpensive oscillator which will not cause any frequency drift nor phase drift over a long period of time (for example, several years). CONSTITUTION: When power is supplied to a phase locked loop, the loop is initialized by a control signal 28 for an oscillator 14 stored in advance in a nonvolatile memory 27 by means of a processor 20. The stored control signal 28 is generated in a manufacturing step of the phase locked loop in response to the reception of a calibrated reference input signal or frequently by means of the controller 12 of the phase locked loop when the loop is normally operated thereafter. Since the signal 29 is stored in the memory 27, the signal 28 is not lost even when electric power is removed from the loop. The stored control signal 28 is used to control the oscillator 14 instead of the output of the controller 12 throughout the period until the loop receives an effective reference signal or a command which instructs the controller 12 to control the oscillator 14.

Abstract: PURPOSE:To prevent the expansion of a contacting window for etching by covering a phosphorus silicate glass film with an insulating film, thereby strengthening the adhering property of a photoresist. CONSTITUTION:An insulating film such as an SiO2 is formed on a phosphorus silicate glass PSG film 5. Then, with a photoresist 7 as a mask a contacting window for etching is produced. According to this step, large excessive etching is not produced due to the presence of a film 8. Then, the photoresist 7 is removed, and the film 8 is converted to a PSG 8' containing high density of phosphorus. The films 5, 8' are then flowed by a heat treatment to flatten the surface. In this manner, the side face of the contacting window becomes smooth. Then, phosphorus glass etching is performed, the electrode pickup metal 6 is deposited, and is etched in the prescribed shape. According to this method, the improper pattern due to the expansion of the contacting window can be extremely reduced.
