Title: Curl straightener
Inventor: NAKAJIMA TOSHIFUMI
IPC: B65H23/34
Filed: 1990-03-02
Abstract: PURPOSE:To perform a proper curl elimination by detecting the existing curl strength of roll paper with a detector built-in a device body through roll paper residual quantity information being recorded in the roll paper, and making it so as to perform the extent of curl straightening congruous to strength of the curl. CONSTITUTION:When a control part receives a record starting command, it sets a position of a guide shaft 4 to P1, performing the record as a residual mark (A) is not yet detected at a time when it gets using a sheet roll 5. When use of this roll 5 progresses and a photosensor 6a detects the residual mark (A), the position of the shaft 4 is set to P2, recording it. When the use of the roll 5 further progresses and another photosensor 6b detects a residual mark (B), the position of the shaft 4 is set to P3, recording it likewise. Moreover, in the case where the use of the roll 5 goes forward and these sensors 6a, 6b detect a residual mark (C), the position of the roll 5 is set to P4 and printing takes place. In brief, the smaller in a diameter of the roll 5, the larger a winding central angle alpha to the shaft 4 of a sheet material 3.

IPC: H03H17/02
Filed: 1988-03-04
Abstract: PURPOSE:To easily obtain a filter without much labor by preparing an equation based on the amplitude value of an output signal from a virtual filter means and determining the coefficient of the virtual filter means with resolving this equation. CONSTITUTION:A recording and reproducing device is composed of a filter 7, whose coefficient is variable, to be the virtual filter means and a coefficient operating circuit 10 to execute an arithmetic processing in order to calculate the filter coefficient based on a reproducing synchronizing signal which is detected by a synchronizing signal detecting circuit 9. Thus, when the arithmetic processing is executed, at first, in a step(Stp)101, the value of a first point, in which the absolute value of the amplitude ot the reproducing synchronizing signal is maximum, and the value of a second point, in which the absolute value is next largest, are obtained. In a Stp 102, the first equation is prepared to cause the values ot the first and second points to be equal. Then, in a Stp 103, the value of a third point, in which the absolute value of the amplitude is minimum, and the value of a fourth point in which the absolute value is next smallest, are obtained. And in a Stp 104, the second equation to cause the values of the third and fourth points to be equal is prepared. After that, in a Stp 105, a resolution is obtained from the first and second equations and the filter coefficient is determined.

Title: Recording device
Inventor: SUZUKI YOSHITAKA
IPC: B41J13/22
Filed: 1994-02-24
Abstract: PURPOSE:To further reduce the cost of a recording device which uses a platen roller having a peripheral length shorter than that of a recording paper. CONSTITUTION:A pair of rotatable rings 11 are provided on both sides in the longitudinal direction of a thermal head 3. The rings 11 have protrusions 11a to which a clamper 14 is attached so as to connect the two rings 11. When a recording paper is pinched by the clamper 14 and the rings 11 are rotated, rollers 17 run on the protrusions 11a, so that the thermal head 3 and a platen roller 4 separate from each other. Accordingly, an actuator for separating the thermal head 3 from the platen roller 4 is unnecessary, thereby reducing the cost.

IPC: B41J2/075
Filed: 1981-04-07
Abstract: PURPOSE:To provide a multinozzle ink jet printer equipped with nozzles of high accuracy which can be easily manufactured at a relatively low cost by tilting a multinozzle ink jet head wherein plural nozzles are arranged in the direction of the row of nozzles. CONSTITUTION:A head 1 is provided with plural nozzles A, B and an image to be printed is divided into the number of nozzle and the image is formed by plural printing spots from each nozzle. Therefore, a high accuracy of arrangement of nozzles is required to improve the accuracy of joints of spots from each nozzle. For this purpose, the accuracy of arrangement is adjusted by tilting the head 1 from the direction X of arrangement, of nozzles. In other words, if it is assumed that the impact position of the left jet is a standard point 0, and the impact position of the right jet A, is deviated from the standard point 0, the nozzle is tilted by an angle of theta so that its impact position comes to impact position B, and the deviation of the nozzle in the direction of Y (paper feeding direction) is corrected by controlling the amount of charged electricity.

IPC: B41M5/42
Filed: 1989-03-03
Abstract: PURPOSE:To obtain a recording medium superior in sheet shelf stability by a method wherein an organic binder contained in a dye transfer contributing layer is composed of at least one selected from among specific resin groups and an expoxy resin. CONSTITUTION:A sublimable thermal transfer recording medium is formed by laminating a dye supply layer 4 and a dye transfer contributing layer 5, each of which is formed by dispersing a sublimable dye in an organic binder, on a substrate 1 in this order from the substrate side. The organic binder contained in the dye transfer contributing layer 5 is composed of at least one selected from among groups of polyvinyl butyral, ethyl cellulose, cellulose acetate propionate, and satd. polyester resins and an epoxy resin. The epoxy resin having a number average molecular weight of about 10000 or more is esp. preferable. The use of an epoxy resin having a number average molecular weight less than 10000 tends to deteriorate characteristics, such as heat resistance, oil resistance, and printing density. The resin selected from among the polyvinyl butyral or other resin groups and the expoxy resin are preferably used in a weight ratio of the former: the latter = (90-20):(10-80) from the standpoint of oil resistance and printing density.

Abstract: PROBLEM TO BE SOLVED: To obtain a multi-beam characteristic up to a sufficiently small separation angle and to make a optical path length difference between respective beams negligibly small by installing respectively specific plane mirrors and aberration correction mirror planes in a symmetrical form symmetrically with respect to a center axis. SOLUTION: The antenna is provided with plane mirrors 4 arranged at a beam waist position of a radio wave from a sub reflecting mirror 2 and aberration correction mirror planes 5 correcting wave front aberration caused in a main reflecting mirror 1 and the sub reflecting mirror 2 to convert the received wave into a spherical wave. Then a light beam 6 of a beam 1 and a light beam 7 of a beam 2, a minimum separation angle of the beams 2Θmin an aperture diameter D of the main reflecting mirror 1, and an aperture diameter Dp of each plane mirror 4 are shown in figure. In this case, the two sets each of the plane mirrors 4 and the aberration correction mirror planes 5 arranged at both sides of a center axis 3 are arranged in a symmetrical form symmetrically with respect to the center axis 3.

Filed: 1985-03-15
Abstract: PURPOSE:To perform the detection of phase angle accurately all the time, by dividing a reference signal and a timing signal, while using the phase difference signal obtained in finding the exclusive OR, and detecting the phase angle of a timing control device with total time of the phase difference signal included in a rotational period. CONSTITUTION:An injection timing signal (a) obtained by a solenoid pickup 5b of a timing signal detector 4 and a reference signal (b) obtained by another solenoid pickup 4b of a reference signal detector 4 are divided by each divider inside an electronic control unit 6 whereby each of signals (c) and (d) is secured. Since the signal (c) comes into a state of making its phase advance forward to the signal (d) as long as the time corresponding to the phase angle, if each exclusive OR of these signals (c) and (d) is found, a phase difference signal (e) is formed there. Accordingly, this signal (e) is counted with a short clock pulse, and among these count numbers, a phase difference between input and output shafts of a timing control device 2 is calculated from a ratio between total time of the phase difference signal included in a period T per rotation of a cam shaft 31 and the said period T.
