Title: Image forming device for reversible thermosensitive recording film
Inventor: HARADA TOMOSHI
IPC: G03G15/20
Filed: 1992-08-20
Abstract: PURPOSE:To avoid influence on a plain paper sheet and a reversible thermosensitive film (TC film) caused by the heat of a heating device or a thermal fixing device and temperature in a machine by inhibiting an image from being formed on the plain paper sheet in the case the sound of the heating device is equal to or above specified one. CONSTITUTION:A heating head 3 is provided with a function for heating the TC film to temperature at which the transparent part of the TC film is changed to opaque white to be initialized. When the TC film passes through a nip part between a resist driving roller 9 and the head 3, it is heated by the head 3 to the temperature at which all the surface of the TC film is changed to the opaque white, and the recorded image of the TC film is automatically erased even in the case of carrying the already recorded TC film. Since the image is inhibited from being recorded on the plain paper sheet in the case the temperature of the head 3 for initializing the TC film becomes equal to or above the specified value, needless heat is not given to the plain paper sheet by the head 3 and the curl of the plain paper sheet caused by the heat is prevented.

Filed: 1989-08-30
Abstract: PURPOSE: To display an extended definition television(EDTV) signal on an NTSC receiver with satisfactory vertical resolution by forming the EDTV signal having an image section and a lateral edge section respectively consisting of images having specified aspect ratios. CONSTITUTION: The EDTV signal having an image section 14 of an aspect ratio 16:9 and a lateral edge section 16 adjacent to that image while having the aspect ratio 4:3 of its entire image is formed, transmitted by an NTSC system and received by a standard NTSC receiver so as to be displayed as a 4:3 image satisfying the picture of aspect ratio 4:3 while including the 16:9 image and one lateral edge section at least. The receiver having a 16:9 screen horizontally and vertically enlarges the image of the received EDTV signal, forms an enlarged output signal corresponding to the enlarged image, and displays only the enlarged 16:9 image on the screen without the lateral edge section 16. Thus, the EDTV system capable of displaying the image high in vertical definition even on the NTSC receiver is obtained.

Abstract: PURPOSE:To arrange so that the capacity of a FIFO memory may be minimized by providing a reading headfor a pattern printed immediately after a printing machine to fix a toner image and collating a data signal with an output data of a delay means. CONSTITUTION:Pattern data signal D1 from an input device C forms a toner latent image in a photosensitive drum 1 through a modifier 3 and a beam direction changer 4, and transfers the image to a printing paper A and fixes it with a printing machine 7. This fixed pattern is detected by an optical reading head 10 arranged right after the printing machine 7 into a pattern data signal through an optical system 10, a photosensor 11 and a signal processing circuit 12. After this process, the signal is inputted to a collation decision circuit 16. Further, the circuit 16 inputs only a signal D1 delayed by a delay means 15 only by time required for passage from a latent image forming point S to the head 10, and collates both pattern signals to judge whether or not the print is satisfactory. If not satisfactory, the circuit actuates a punch 14. Thus it is possible to scale down FIFO memory in the delay circuit.

Title: Pulse generator
Inventor: HORIE TAKAO
IPC: H03K3/53
Filed: 1984-10-25
Abstract: PURPOSE:To stabilize the conduction interrupting action of a thyristor by connecting in parallel a diode to an oversaturated choke coil interleaved between the thyristor and a pulse shaping circuit as an electric charge accumulating circuit. CONSTITUTION:Two SCRs 7a, and 7b serially connected between the electric power source side terminal of the pulse shaping circuit network (PFN) and the grounding side terminal of a pulse transformer 5 through the oversaturated choke coil 6. The diode 21 with the SCR 7a side as straight polarity is connected between both terminals of the oversaturated choke coil 6. Thus, even if the oversaturated choke coil 6 is in the non-saturated state, a discharging current in the reverse direction flows in the direction of a PEN4 through the diode 21, and therefore an apparent impedance value drops. As a result, the discharg ing current ic converges to a zero level in a short time. Accordingly, the SCRs 7a and 7b can securely interrupt a current even if the impedance value of the oversaturated choke coil 6 is increased to some extent. Since the oversaturated choke coil 6 is interleaved between the PFN4 and the SCR 7a,the characteristics of the SCRs 7a and 7b at conduction can be made approximately uniform.

Title: Image sensor
Inventor: MURATA TAKAHIKO
IPC: H04N1/19
Filed: 1986-09-19
Abstract: PURPOSE:To attain a highly accurate reading with a less after image by obtaining an optical signal from a charging current arising in a 1st charging period, reducing the output impedance of an image sensor with the aid of a means setting the emitter of a phototransistor to a ground state and executing a 2nd charge. CONSTITUTION:In order to discharge charges accumulated in a load capacity 9 so as to attain a cleared state, a discharging pulse 14 is impressed during a period t3. During the period T3 a discharging switch is turned on, and the emitter of the phototransistor is grounded, thus, the output impedance is the lowest. If in synchronization with the period t3 or during that period t3 a charge pulse 13 is impressed during the period t3 (the 2nd charge), insufficient charges can be make up efficiently by impressing(the 1st charge) during the period t3. Since not only the 1st charge but also the 2nd charge are executed, the charging quantity can be increased, by which charges are inputted to the reverse junction capacity between the base and collector of the phototransistor. Thus the highly accurate reading is attainable with the less after image.
