Title: Coupling circuit
Inventor: SAITO TAKESHI
IPC: H01P5/04
Filed: 1987-01-30
Abstract: PURPOSE:To optimize the tuning and matching by employing a single tuning type band-pass filter comprising a 1/2 wavelength or 1/4 wavelength resonance line constituted by a microstrip line and using a flexible conductor line for the signal input and output part so as to couple them in terms of high frequencies. CONSTITUTION:A urethane clad copper wire (nearly 0.2mm-0.4mm) is used for flexible conductor lines 4, 5, one end is connected electrically and mechanically to the end of the input or output line by solder, the other end of the flexible conductor line 4 or 5 not fixed is arranged closely to the resonance line 3 to obtain a single tuning band pass characteristic by using the resonance line. The flexible conductor lines 4, 5 show a state adhered closely to the resonance line 3 in figure. Moreover, the 1/2 wavelength type resonance line 3 is shown in this case, but the 1/2 wavelength type line offers the similar effect. Furthermore, the similar insulation effect is obtained by applying cover coat to the resonance line 3 to attain the DC blocking.

Title: Magnetic ink medium
Inventor: YAMAGUCHI YOSHITAKA
IPC: B41M5/382

Abstract: PURPOSE:To enhance releasability from a support and to enable high grade printing even to a transfer paper inferior in surface smoothness or a film inferior in the compatibility with ink, by having a thermally expansible substance of a heat-decomposable substance contained in a magnetic ink layer. CONSTITUTION:In a non-contact type magnetic printing apparatus, the thermoplastic magnetic ink 35 of an ink medium 32 comes into contact with a transfer paper 33 at the time of the application of heat from the surface of a support 36 by a thermal head 31 (at the position directly under the thermal head) and, after the molten ink 35 is adhered to the transfer paper 33, the ink medium 32 is peeled off from the transfer paper 33 to transfer the ink. At this time, the release of the magnetic ink layer after heat melting from the support 36 is performed not only by a magnetic attraction means but also by the action of the gas as a release agent generated by the destruction or decomposition of the microcapsule having a thermally expansible substance (n-butane) included therein or heat-decomposable substance (azo compound) contained in the magnetic ink layer or by applying the pressure or impact force of gas to the molten ink, thereby enhancing the releasability of the ink from the support.

Title: Electrophotographic printing device
Inventor: MARUYAMA AKIRA
IPC: G03G15/02
Filed: 1986-01-30
Abstract: PURPOSE:To always obtain normal printing record by providing a contact type electrostatic charger with plural contact charging brushes mutually separated and insulated and a power supply having a control part for controlling excess current at the detection of the excess current to the brushes. CONSTITUTION:Since a pin hole 6 of a photoconductive body 1 is always allowed to contact with the contact charging brush 2 during the period from the start of the contact with the brush 2 up to the end of the contact, a current more than a prescribed value is conducted into the brush 2 at the impression of a prescribed voltage and voltage drop or the growth of the pin hole is generated. A control part 3 always monitors the flowing current, and when detecting that the current is excess current exceeding a previously set fixed value, turns off the power supply 5 for a prescribed period to interrupt the conduction of the excess current. The time from the OFF of the power supply 5 after the detection of the excess current up to the restriction to the original ON state is set up based on the width of the brush 2 and the advancing speed of the photosensitive body. Consequently, a fine image with uniform density can be obtained and solid black reproducibility can be also improved.

Title: Discharge lamp lighting device
Inventor: NISHIIE MICHIHIKO
IPC: H05B41/24
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To provide a discharge lamp lighting device which constantly maintains the output voltage of an inverter circuit when removing a discharge lamp. SOLUTION: When the voltage across an inverter is high because of variations or the like of parts, the voltage across a capacitor C13 is increased. Since the current flowing through a light emission diode LED2 is large, the resistance value between the emitter and collector of a phototransistor Q16 is lowered to approach a state of perfect conduction close to saturation. Therefore, the current flowing through a light emitting diode LED1 is increased to lower the resistance value between the collector and emitter of a phototransistor Q7, thereby lowering the output of an inverter circuit 2 by a control circuit 3. In the contrary case where the voltage of an output terminal of an inverter is low, the output of the inverter circuit 2 is increased by the control circuit 3 through the contrary operation.

Title: Method of detecting the number of sheets
Inventor: MATSUNAGA JUNJI
IPC: G06F3/023
Filed: 1989-01-30
Abstract: PURPOSE:To easily exclude the influence of external light by means of a simple constitution by arranging a DC interrupting element on the light receiving side, converting irradiating light into pulse light and inputting the output of the photodetector synchronously with the irradiation of the pulse light. CONSTITUTION:When an I/O port P1 is 'H', external light is made incident upon a phototransistor(PT) 29 through a through-hole 21 collector current flows and the potential of a node CP1 is held at V1. Since PTs 30 to 32 are covered with definition sheets 3 to 6, external light is not directly inputted to the PTs 30 to 32 and the potential of the nodes CP2 to CP4 is held at V2 by light passing between the sheets. Although the potential of the node CP5 is held at potential V3 at the time of connecting a diode 47, the charge of capacitors 39 to 42 disappears for 1 to 2msec and the influence of external light is interrupted. Light emitting diodes 25 to 28 are turned on by pulse, the emitted light is reflected by definition sheets 2 to 6 and made incident upon the PTs 29 to 32, the potential values of the nodes CP2 to CP4 are changed by the collector currents of the PTs 29 to 32, and the outputs of comparators 44 to 46 are inputted to an MPU 34 synchronously with the pulse light from the diodes 25 to 28 to detect the sheets 2 to 6.
