Title: Exciting circuit for ink jet printer
Inventor: FURUKAWA ISOKAZU
IPC: B41J2/175
Filed: 1980-12-15
Abstract: PURPOSE:To provide a circuit which can rapidly respond to a temperature change by means of a simple and inexpensive constitution, by a method wherein a change in an electric resistance against an ink temperature is directly detected, and this controls a gain of a gain control circuit and an excitation voltage. CONSTITUTION:Electrodes 5a and 5b are mounted at a part of an ink feed tube 4 in a manner to make contact with ink. A resistance value Ri between electrodes 5a and 5b is a resistance value of ink which changes according to a temperature change of ink, and is approximately inversely proportional to a gain C of an operational amplifier 6. That is, it is generated G Rf/Ri, where Rf is a resistance value of a feedback resistance 7. Or, in the case of a high temperature, the resistance value Ri falls, and thereby a gain of a gain control circuit, consisting of the operation amplifier 6 and the resistance 7, increases, and as a result, an excitation voltage increases to compensate for temperature. In the case of ink breaking, the resistance value Ri increases very extremely, whereby the excitation voltage attenuates, and piezo-electric vibrator can be prevented from deterioration to be caused due to its heating.

IPC: B41J7/48
Filed: 1983-09-22
Abstract: PURPOSE:To prevent component parts of a type wheel from being abraded, broken or damaged and obtain a highly reliable printer free of misprinting, by a method wherein a type wheel resetting operation is effected through gears. CONSTITUTION:When an intermittent gear 5 is rotated in the direction of an arror A by motive power of a motor, the first driven gear 401 of a selecting gear is rotated by the first driving gear 501. A type wheel shaft 2 fixed to the gear 401 is rotated in the same direction, and the type wheel is also rotated by the function of a type wheel spring. Since a detecting plate fixed to the shaft 2 is also rotated, a signal corresponding to the movement of the type wheel is provided by a detector. An electric current is supplied to an electromagnet in synchronism with the signal to operate a lever, therby selectively positioning the type wheel at a predetermined position. Although the type wheel is stopped at this position, the type wheel shaft 2 is rotated further, and one end of the type wheel spring is disengaged from a V-groove of the shaft 2.

The pre-processing unit 60 applies preliminary processing to the signal vector. The preliminary processing is conducted by subtracting a decoding result obtained by decoding the signal vector subjected to preliminary processing by the pre-processing unit 60 from the signal vector under processing at present and nullifying elements of the signal vector having been received after the signal vector under processing at present and not processed yet from the signal vector under processing at present. The decoder 65 decodes the result obtained from the preliminary processing of the signal vector.

Abstract: PURPOSE:To aim at enhancing smooth engagement, by returning toward a switch-back section, decelerating or stopping a preceding sheet once to prevent the leading end of a succeeding sheet from being distorted or bent when the preceding sheet which has been switched back passes by the succeeding sheet. CONSTITUTION:When a preceding sheet on a discharge path 129 passes by a succeeding sheet led to a switch-back section, the leading end of the succeeding sheet is detected by a sensor S1, and when the it reaches a change-over gate 109, a discharge roller 111 is reversed in rotation to advance the preceding sheet once toward a discharge port 123. As a result, the preceding sheet is returned toward the switch-back section so that the leading end of the succeeding sheet is engaged with the preceding sheet, and therefore it is smoothly led into the switch-back section. After the engagement between the succeeding sheet and the preceding sheet, the roller 111 is normally rotated to discharge the preceding sheet onto a tray 103. Further, when a sensor S2 detects the trailing end of the succeeding sheet, a reversible roller 105 is reversed in rotation to switch back the succeeding sheet, thereby sheets are successively discharged onto the reversing tray 103 from a discharge port 127.

Title: Metallic mold for duplication of optical disk
Inventor: MIYADERA TOSHIYUKI
IPC: G11B7/24
Filed: 1986-07-29
Abstract: PURPOSE:To enable easy removal of the protrusion of a coated photo-setting resin by the pressurization of a substrate by forming a layer of a material having the low frictional characteristics and water repellency to repel the photo- setting resin to the outside and inside of a rugged pattern for forming pits and grooves of a metallic mold for duplication. CONSTITUTION:A layer 4 of fluoroplastic is formed on the part inner than the outside diameter of the substrate 3 and the part outer than the inside diameter thereof and after the photo-setting resin 2 is coated on the metallic mold 1, the substrate 3 is imposed thereon and is pressurized. Since the excess photo- setting resin 2 protrudes to the inside and outside peripheries of the mold 1, the fluoroplastic layer 4 of the mold 1 has the property to repel the photo-setting resin; i.e., the low frictional characteristic and water repellency; therefore, the photo-setting resin is removed from the mold 1 without remaining on the outside and inside peripheral faces of the mold 1 by the removal treatment. The substrate 3 is then projected with rays from above, thus the photo-setting resin 2 is cured; thereafter, the photo-setting resin is stripped from the mold 1. The fluoroplastic 4 has the low frictional characteristic and therefore, is easily strippable.
