IPC: G11B7/26
Filed: 1985-12-27
Abstract: PURPOSE:To determine the center of rotation of grooves for information and the center of the through-hole of a disk-shaped substrate with good accuracy by depositing a metallic film on a base plate consisting of glass, etc. then subjecting the same to positioning and working by making use of a difference in light reflectivity. CONSTITUTION:A chromium film 13 is deposited by a sputtering to 700Angstrom  thickness on the base plate 1 formed by depositing a 1,500Angstrom  silicon oxide film 122 by an electron beam vapor deposition method on the surface of the soda lime glass substrate 12 subjected to precision polishing to a rectangular shape having 1.2mu thickness. A positive type photoresist film 14 is further coated to 1,000Angstrom  thickness thereon by using a spin coating device and is subjected to prebaking to form the base plate. A photomask and the base plate are brought into tight contact with each other in such a manner that the chromium pattern 112 of the mask and the photoresist film 14 face each other. UV rays 15 are irradiated on the photoresist film to transfer the chromium pattern 112 to the photoresist film 14. The film is thereafter developed and etched to form the chromium pattern 13A corresponding to the grooves for information. The oxide silicon film 1122 is then dry etched with the chromium pattern 13A as a mask to form the grooves 16 for information to the concentrical shapes spaced at 2mum. The central position of the chromium pattern 13A is determined by using a microscope which permits reading in 1mum unit. A through-hole of 15 (+0.05, -0.0)mm diameter is bored by a shaping machine which can make precision positioning. A core bar is inserted into the hole and the base plate is formed to the disk shape of 130+ or -0.05mm outside diameter by rotary grinding. The chromium pattern 13A is finally removed by etching.

Title: Clear signal generating circuit
Inventor: SUGINO HIROYUKI
IPC: G04C10/00
Filed: 1989-11-10
Abstract: PURPOSE:To eliminate the variance of time until a clear signal is outputted after a timing pulse is generated by providing a capacitor whose capacity is comparatively small on a transfer means. CONSTITUTION:The capacity of a capacitor 14 of a transfer circuit 202 is made considerably smaller than the capacity of a capacitor 8 of a smoothing circuit 203. A pulse signal (e) outputted from a NOR circuit 6 of a detecting circuit 201 becomes a signal for detecting a leading edge of a timing pulse (a), and a pulse signal (d) outputted from a NAND circuit 12 becomes a signal for detecting a trailing edge of the timing pulse (a). The time until a clear signal (j) is varied from '1' to '0' after the timing pulse (a) starts to be outputted is determined by a ratio of the capacity of the capacitor 8 and the capacity of the capacitor 14 and a frequency of the timing pulse (a), and it does not depend on a resistance value of a resistance 5a for constituting a delaying circuit 5, and a capacity value of a capacitor 5b. In such a way, the time until the time of generation of the clear signal from the time of generation of the timing pulse can be made constant.

Title: Paper feeder
Inventor: SUGIMURA NAOTO
IPC: B65H1/24
Filed: 1995-10-18
Abstract: PROBLEM TO BE SOLVED: To soften impact at meshing of a gear partially lacking teeth with a perfect gear by preventing the force energizing a cassette plate on the roll side from contributing to rotation of a cam engaging with the cassette plate and a paper feed roll. SOLUTION: A paper feed roll 2 and a cam 19 are combined with a driven gear partially lacking teeth. At feeding no paper, the cam 19 is engaged with the edge 17 of a cassette plate 14 so as to push down the cassette plate 14. The form of the contact face with the edge 17 is set as follows. Namely, directly after releasing a lock means for holding the paper feed roll 2 on the prescribed position at feeding no paper, in short, at meshing of a driving gear with the driven gear, the contact face 22 is formed so that the pushing up force N by a compression spring 21 only acts in the direction of a shaft 1. By this constitution, the pushing force N does not contribute to meshing of the driving gear with the driven gear, and hence impact at meshing can be softened.

Filed: 1987-11-24
Abstract: PURPOSE:To obtain stable liquid crystal and stable printing quality by performing control of liquid crystal display density and control of image density with one temperature sensor, by a method wherein the title printer is so constructed that ambient temperature of an arrangement part of a liquid crystal display and of an arrangement part of a photosensitive material are almost equalized. CONSTITUTION:A temperature sensor 3 detects a temperature in a liquid crystal display in which a liquid crystal display part 2 enclosed by a cover 5 is fixed to an operation panel 1, and sends the detected data to a liquid display control circuit 4 and a charge voltage generation circuit 7. Since the liquid crystal display is covered by a cover 5, a temperature increase characteristic around a photosensitive material is approached by regulating a size of the cover and a quantity of air flow. Since display density of a liquid crystal display is thickened as temperature rises a circuit 4 is so operated as to lower driving voltage according to increase of ambient temperature. Since surface charged voltage of the photosensitive material decreases as temperature increases, the charged voltage is increased with the circuit 7 according to increase of ambient temperature. When the surface of the photosensitive material 6 is charged with a specific electric charge, a liquid crystal display and a printing image density can be made constant.
