IPC: G03G15/04
Filed: 1989-04-07
Abstract: PURPOSE:To remove irritated feeling to be generated in printing waiting time when a printer uses page descrimption language(PDL) by a allowing an operation display part to inform the advancing state of bit image processing to a user. CONSTITUTION:A CPU 4 in a printer controller part 1A recognizes the number of lines 11B (N lines) of serial video data to be written in the printing area 11A of paper 11. The CPU 4 sequentially compares the recognized number 11B of lines with a bit image stored in the RAM 6 and generated from a bit image generating part 5 and calculates which line of the serial data corresponds to the position up to which bit images have been already stored in the RAM 6. At that time, the calculated result stored in the RAM 6 is inputted from the printer controller part 1A to a CPU 101 in the operation display part 10 and the CPU 101 drives a driving part 102. In the case of driving an LED 103 by the LED driving part 102, which position of the printing area 11A is occupied by the bit image stored in the RAM 6 is displayed, and informed to the user. Consequently, irritated feeling for the printing waiting time can be removed.

Title: Discriminating device for analog signal
Inventor: TSUJII TATSUO
IPC: G01R19/00
Filed: 1980-06-26
Abstract: PURPOSE:To perform highly precise discrimination through simple constitution by discriminating output states of two analog signals on the basis of the output polarities of two ocmparators which are applied with a differential amplification output and differ in reference set voltage. CONSTITUTION:The same digital signal is passed through D/A converters 111 and 121 to obtain independent analog signals, which are processed by a differential amplifier 14. Its differential amplification output is applied to the normal input and inverted input terminals of comparators 16 and 17 which are applied at their inverted and normal input terminals with reference voltages differing in polarity. When both the analog output signals of the converters 111 and 121 are the same, the outputs of the comparators 16 and 17 has the negative polarity and a high-level discrimination output is generated through diodes D1 and D2 and an AND circuit 18. Even if a bit fault or the like occurs to the converter 111 or 121 and an analog signal difference can not be discriminated by indicators 13 and 14, the comparison output of the comparators 16 and 17 change in polarity. Thus, the discrimination output is inverted and the simple constitution discriminates analog signal output states with high precision.

Title: Photographic copy screen for electronic copying machine
Inventor: SHIROTORI SANOE
IPC: G03F5/04
Filed: 1983-05-17
Abstract: PURPOSE:To increase the accuracy of a copy of a continuous gradation part and to copy a face, stripe patterns of clothes, etc., accurately by providing halftone dots onto the under surface of a transparent film and forming a rugged mat surface on the top surface. CONSTITUTION:Halftone dots 3 of small black dots 2 are printed on the under surface of the transparent plastic film 1 and the rugged mat surface 4 is formed on the top surface. The mat surface 4 is frosted because of its ruggedness. A photograph (b) is placed on contact glass (a) for copying. The photograph is copied with light from a light source (c) in the form of whether a small black dot 2 is present or not. Diffused reflection is caused by the rugged mat surface 4, and there are therefore intense and weak light parts on close view; and the light is projected on a photosensitive body and a latent image of the original is formed on the photosensitive body and copied. Consequently, not only dots, but the light of the diffused reflection is adjusted and continuous gradations of the copying are represented more delicately.

Title: Method and apparatus for driving coil
Inventor: SUZUKI NAOHISA
IPC: G05F1/56
Filed: 1985-04-25
Abstract: PURPOSE:To generate a large energy of a coil in a short time even with a power supply having a load fluctuation by increasing smoothly and tentatively a current value just after the leading at constant current drive. CONSTITUTION:While a hammer energyzing signal Ts/ is active (low level), when power application of a coil 31 is caused, a command voltage V1 generated in a time constant circuit 27 at the leading of the output of an open collector inverter driver (OC) 26 is decreased with a prescribed time constant. Then a voltage follower 28 drives a detection voltage V1 of a current detection circuit 30 in matching with an indication voltage V1 of the time constant circuit 27. Thus, the coil 31 is driven with the current leading characteristic specific to the coil 31 at first and then the coil 31 is driven by a current proportional to the voltage trailing characteristic of the time constant circuit 27. Thus, just after the start of driving, the coil generating energy is kept largely and then the coil is driven stably with a prescribed constant current.

Filed: 1986-04-18
Abstract: PURPOSE:To enable the printing to a rough surfaced paper by making it possible to sufficiently and closely contact a head with the rough surfaced paper having large unevenness, by a method wherein the cross-sectional shape of a glaze layer region is formed in the longitudinal direction thereof so that the area thereof corresponding to the max. temp. heat generating part of a heat generating resistor comes to a recessed part. CONSTITUTION:The cross-sectional shape of the glaze layer 2 formed on an insulating substrate 1 comprising alumina ceramic is formed so as to have two projections between which a central recessed part is formed. The glaze layer having this shape can be formed by a method for molding a glaze layer after usual printing and baking by etching or a method for fusing and bonding two partial glaze rows after printing and baking. The resistor layer 6 between electrode layers 4, 4' comes to a heat generating resistor. The contact pressure of the heat generating part and recording paper becomes large at the projected parts and the close contact of both of them is improved because the protruded parts of rough surfaced paper having large unevenness are collapsed to a certain degree and the projections of the head becomes easy to penetrate into the recessed parts.

Abstract: PROBLEM TO BE SOLVED: To correctly detect a boundary of a data recorded area and a writable area by judging as the boundary a block which becomes a read error and is a point of an integral multiple of a specific packet length from a head of data. SOLUTION: In the case of a fix packet where a track # (m) has a packet size = x, each packet is formed of (7+x) blocks, that is, (x) user data blocks and seven other blocks (link blocks, run-in block, run-out block). In other words, a next block (=link block to be a boundary) to a data end Q of the track #(m) is located at a position of an integral multiple of a packet length (7+x) from a track head P at all times. Therefore, even if a CRC error is brought about to blocks other than the link block of the boundary, the boundary can be correctly judged.
