IPC: H04N5/335
Filed: 1988-10-13
Abstract: PURPOSE:To set a width of a photosensitive section of a photoelectric transducer section whose metal coating is removed to a specified size accurately by arranging a plurality of slit-like metal-coating-free sections which are as wide as an opening of the photosensitive section of the photoelectric transducer section and by etching a metal coating on the photoelectric transducer section while observing an etching pattern which is provided with a V-shaped notch properly away from an end of the metal-coating-free section. CONSTITUTION:An amount of over-etching of an opening width of a photosensitive section is determined by the state of change of L0 to L5 through etching. Here, widths W0 to W2 of metal-coating-free sections should be equal to the opening width of the photosensitive section or at least 70% thereof so that the etching effect of the metal coating is the same as that of the photosensitive section. An etching pattern is etched together with the opening region of the photosensitive section of the photoelectric transducer section. Since a meeting point (d) of a point of a V-shaped notch of the metal coating and an end section of the metal-coating-free section is in an area of L2 of zero, the overetching amount of an opening width of the photoelectric transducer section becomes known to be L2 accurately.

IPC: B41J35/28
Filed: 1988-10-14
Abstract: PURPOSE:To prevent upper and lower cases from damaging at the time of filling of an ink ribbon and to eliminate the adjustment even if the length of a ribbon cartridge with a rib is altered by providing a fluctuation between a rib attached to the cartridge and a groove cut on a holding plate. CONSTITUTION:While a knob 9 is raising, an arm 8 is rotated in a direction A to move a resin retaining member to a position for retaining a ribbon cartridge 13 with a rib. When the knob 9 is released from a hand, the member retains the cartridge 13 by the spring force of a spring member. Then, a driving motor is driven to fill and ink ribbon in the cartridge 13. In this case, the central deviation of a ribbon feeding roller 3 and a driving shaft 11 is absorbed by the fluctuation between a rib 4 and a groove 10. After the ribbon is completely filled, the knob 9 is raised to rotate the arm 8, and the cartridge 13 is removed. Even if the length of the cartridge 13 is varied, adjustments such as alteration of positioning, alteration of the holding plate are not required.

A repeating mode releasing part 13, when the execution of the repeating is completed, releases the repeating mode. Thus, the number of characters, which the operator wants, can be designated and the input speed can be fastened.

Filed: 1991-10-07
Abstract: PURPOSE:To provide an optical connection device which can easily secure the non-reversible connection between the optical elements by providing these elements having the different optical paths by polarization, an optical system.

Title: Current detection circuit and its inspection method
Inventor: KUBO SHINJI
IPC: G01R15/14
Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To unrequire a device for generating a large current and inspect in safety and with high precision by a method wherein a voltage supplying part is formed between a partial pressure resistor disposed in a route from a high voltage side of a shunt resistor and an input part of a differential amplification circuit and an impedance conversion circuit. SOLUTION: For example, when 1 V is applied to a voltage supplying part 15, this 1 V is input to an impedance conversion circuit 7. On the other hand, as 1 V is divided by resistors 3, 5, 6 (a shunt resistor 2 is ignored due to 0.1 Ω, or small resistance), an input voltage of an impedance conversion circuit 8 is 0.333 V which is almost obtained by trisecting 1 V. Accordingly, an input voltage into a differential amplification circuit 20 becomes 1-0.333=0.666 (V), and a voltage appearing at a terminal 14 becomes 0.666×5.1=3.404 (V). Namely, for example, 1 V is applied to a voltage supplying part 15, and it is measured what amount a voltage appearing at the terminal 14 shifts from a theoretical value, and it is judged whether or not this current detection circuit is within a predetermined precision scope.
