Title: Thermal printer
Inventor: MINOWA MASAHIRO
IPC: H04N1/23
Filed: 1985-07-11
Abstract: PURPOSE:To maintain a constantly fixed density irrespective of data to be printed, by a system wherein series circuits of a diode and a resistor are connected to output terminals for heating resistors, other ends of the series circuits are connected in common, and energy to be applied to the heating resistors is determined by the charging level of a capacitor having an end connected to the common connection. CONSTITUTION:The other ends of the plurality of series circuits 4 are connected in common to the capacitor 7.By appropriately selecting the values of resistors 91, 93, a Zener diode 92, the capacitor 7, the resistors 6 or the like, it is possible to set the time constants for charging and discharging to be approximate to those of cooling and heating, respectively. With the charging level Vc as a reference, the charging time for a pulse width converting capacitor 10 is converted into a pulse width tw through a voltage-comparing circuit 14, whereby the pulse width tw is set to be smaller for a lower value of Vc, namely, for a higher thermal head temperature and to be larger for a higher value of Vc, resulting in that the applied energy is so controlled that the printed density is constantly suitable for the temperature of the thermal head 1.

Title: Conveying mechanism for film leader for developing device
Inventor: TSUKADA TADAHARU
IPC: G03D3/08
Filed: 1990-06-12
Abstract: PURPOSE:To convey the leader in leader inversion guide parts while engaging it with an endless belt by providing the leader inversion guide members which are so constituted that the internal diameter of the leader guide surfaces of the inversion parts is made larger than the leader track interval of the linear parallel guide part of the endless belt. CONSTITUTION:The inversion guide members 62 and 63 are so constituted that the internal diameter of the leader guide surfaces 66 is made larger than the internal diameters of the leader guide surfaces 66 are made larger than the leader movement interval of the linear parallel guide part of the endless belt 34, i.e. the interval between the movement track of the leader 24 extending to wound sprocket wheels 46 and 47 and the movement track of the leader 24 after inversion. The leader 24, therefore, becomes weak in engagement with the outer peripheral projection 34B of the endless belt 34 at the endless belt inversion part. Consequently, the leader 24 keeps on engaging the outer peripheral projection part 34B loosely again, this state is eliminated once the leader 24 reaches the linear guide part, and engagement hole 32 of the leader 24 engages the outer peripheral projection 34B of the endless belt 34 again, so that the film F is guided. Consequently, the leader never falls off the endless belt even at the inversion part and the reliability of the leader conveyance is improved.

Abstract: PURPOSE:To enable the control of correct delay time and a beam focusing without deterioration a combined performance of the circuit by a constitution wherein an appropriate delay time is added to each of multiultrasonic receiving signals by means of a change-over switch, an adder, a fixed delay circuit and a variable delay circuit. CONSTITUTION:Receiving signals of ultrasonic vibrators 1-1-1-N arranged in an array type pass through a change-over switch 8, adders 3-0, 3-(N-1) and a switch 5 and are delivered to fixed delay lines 6-1-6-N and variable delay lines 7-1-7-N. Further, the output signal of a delay circuit 7 enters the adder 3 where a delay time is added and a connection is made so as to repeat siad procedures sequentially. When deflection angle theta is amall, the receiving signal passes only through the delay line 7 by means of the switch 5, and when the theta is large, it passes through also the fixed delay line 7 by means of the switch 5. A change-over switch 8 is selectively connected by a command from ROM etc. Thus, without deteriorating the combined performance of the circuit, a correct control of the delay time and a beam forcusing becomes feasible.
