Title: Stabilized power circuit
Inventor: TAKADA NAOYA
IPC: H04M1/00
Filed: 1990-02-28
Abstract: PURPOSE:To reduce the variance of the output voltage to that of the input voltage and to improve the stability of a stabilized power circuit by supplying the operating power voltage to a voltage detecting circuit and a constant current source via an operating stabilized power circuit. CONSTITUTION:A stabilizing transistor 2 stabilizes the voltage inputted through an input terminal 1 where the power voltage is inputted. A voltage detecting circuit 4 detects an error between the voltage which is actually outputted through an output terminal 3 and the desired voltage to be outputted and feeds this error voltage back to the transistor 2. A constant current source 5 supplies a constant bias current to the circuit 4. An operating stabilized power circuit 6 supplies the operating power voltage of the circuit 4 and the source 5 after stabilizing the voltage inputted through the terminal 1. Thus the operating power voltage is supplied to the circuit 4 and the source 5 after the input voltage is stabilized by the circuit 6. As a result, the variance of the output voltage is reduced to that of the input voltage. Then, the stability of a stabilized power circuit is improved.

Filed: 1987-03-03
Abstract: PURPOSE:To obtain an invariably stable image by providing a resistance element for correcting the impedance of a primary electrostatic charger in a process cartridge. CONSTITUTION:The output voltage V0 of a high-voltage power source 15 is V0=IR0, where I is a constant current flowing through the electrostatic charging line 2A of the primary electrostatic charger, R0 is the impedance of the primary charger 2, and the resistance value of a variable resistance element 16 is 0OMEGA. When it is assumed that the process cartridge 12 has this impedance and the output voltage V0 is the optimum value (V1+V2)/2 of a transfer voltage, the impedance is R1 (R1<R0) when the distance between the electrostatic charging line 2A and a photosensitive drum 1 is narrowed down for potential correction, and then the transfer voltage V1 becomes V1=IR1<V0 and deviates from the best condition V0. For the purpose, the resistance value R1' of the variable resistance element 16 is set to a value satisfying (R1'+R1)I=V0, i.e. R1'=R0-R1, thereby obtaining the optimum transfer voltage.

Title: Zoom lens
Inventor: OKADA NAOSHI
IPC: G02B15/16
Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To obtain a zoom lens where parallax is not caused, which is compact and whose optical performance is high by constituting so that a zoom component positioned adjacently just before a reflection means performing the division of a luminous flux or the switching of an optical path may have negative power. SOLUTION: This zoom lens is constituted of four groups, that is, a 1st group Gr1 being positive, a 2nd group Gr2 being negative, a 3rd group Gr3 being positive and a 4th group Gr4 being negative in order from an object side; and a half prism HP performing the division of the luminous flux by reflecting the luminous flux after passing through the 2nd group Gr2 is interposed between the 2nd and the 3rd groups Gr2 and Gr3. Since the 2nd group Gr2 positioned adjacently just before the half prism HP has the negative power, an off-axis luminous flux made incident on the half prism HP forms a small angle with an axial luminous flux. Therefore, the luminous flux diameter which should be covered by the half prism HP is restrained to be small, so that the half prism HP is miniaturized.
