Filed: 1984-03-07
Abstract: PURPOSE:To inexpensively manufacture a compact and highly accurate multiplex lens, by forming a preformed lens and low-softening point glass having a different refractive index in one body while the glass is pressed with pressure against the lens. CONSTITUTION:A preformed lens 5 is held by a pressing machine 8. Low-softening point glass 6 having a different refractive index from that of the glass constituting the lens 5 is held by a holder 10. Then a forming mold 9 is fitted to the front end of another pressing machine 7 and the pressing machines 7 and 8 and holder 10 are aligned on the same axis. Then, after all of them are heated to the softening point of the glass 6, the pressing machines 7 and 8 are pressure-contacted.

Filed: 1985-03-04
Abstract: PURPOSE:To eliminate a difference in frequency of use between two photosensitive bodies by controlling to replace a reference photosensitive body when the difference in frequency of use between the photosensitive body increases to some extent. CONSTITUTION:When a copy cycle is entered, the counter area 12 in a RAM 11 is used for counting to integrate the difference in frequency of use between the photosensitive bodies 1 and 2. Further, when a copy button is pressed, a CPU 13 judges whether the absolute value of the integration result in the counter area 12 is larger than a specific value or not before movement to the reference position of the photosensitive body 1 or 2. When the absolute value of the integration result is larger than the specific value, the photosensitive body 1 or 2 set in a reference photosensitive body setting area 14 is replaced. Consequently, when the difference in frequency of use between the photosensitive bodies 1 and 2 increases to some extent, the photosensitive body 2 or 1 which is smaller in frequency of use replaces the reference photosensitive body and is used firstly at the start of the copy cycle which is entered with the copy button.
