Title: Ultrasonic wave absorbing device of inkjet printing head
Inventor: MORITA NAOKI
IPC: B41J2/02
Filed: 1988-09-07
Abstract: PURPOSE:To attenuate ultrasonic waves thereby to eliminate a reflecting wave and to make the device compact in size by setting the length of an ultrasonic wave absorbing member over three times the wavelength of a ultrasonic wave spread in said absorbing member. CONSTITUTION:In forming an ink drop D, ultrasonic waves are produced by an ultrasonic wave exciting and oscillating device 12, which are then applied to an ink within an ink passage 8. When the ultrasonic waves reach an ultrasonic absorber 13 through the ink passage 8, they are incident upon a silicone rubber 30 of the absorber 13 without being reflected at the surface of the rubber because the silicone rubber 30 has approximately the same acoustic impedance as the ink. The ultrasonic waves are hence attenuated. If the length of the silicone rubber 30 is set about three times the wavelength of the ultrasonic waves when they are spread in the silicone rubber 30, the silicone rubber can absorb the ultrasonic waves without generating a reflecting wave. Accordingly, the ink drop D can be formed stably and the device can be compact in size.

Title: Abc circuit
Inventor: BANDO JUNICHI
IPC: H04N1/407
Filed: 1985-10-04
Abstract: PURPOSE:To obtain an even picture quality regardless of a transmission speed by adding a switching circuit on a time constant circuit, and controlling an amplifier circuit operating the switching circuit. CONSTITUTION:An analog picture signal H read from a CCD is amplified with a variable amplifier circuit 21. When the amplified waveform is generated over a specified level, the output of a comparator 22 becomes a high level, and a capacitor 23a in a time constant circuit 23 is charged. Also, simultaneously the voltage of a control voltage K rises and the resistance of a variable resistor 21a is reduced, and an input level to an operational amplifier 21b is lowered, the output level of the amplifier circuit 21 being lowered. On the other hand, when the level of the picture signal His lowered, the output of the comparator 22 becomes a low level, the capacitor 23a is discharged while a switching circuit 24 is turned on, and the resistance of the variable resistor 21a is increased, thereby raising the output level of the amplifier circuit 21.

Abstract: PURPOSE:To quickly and surely detect misconnection at the time of replacement for a fault. CONSTITUTION:At the time of the start of transmission, a channel number file F consisting of the channel number, operation state information, and channel number enable information is transmitted from an arithmetic processing part 1 in the operating state to an input/output control part 21 with respect to each connection channel, and the input/output control part 21 generates report information consisting of the channel number and channel number enable information from the received channel number file F and transmits it to an arithmetic processing part 11 in the standby state through internal busses 27 and 28. The arithmetic processing part 11 discriminates whether the reception channel number of report information and the channel number stored in report information coincide with each other or not, and discriminates the abnormality of connection to stop the processing operation in the case of the noncoincidence.

Title: On-screen display circuit for color television receiver
Inventor: KUNII YORIKUNI
IPC: H04N5/445
Filed: 1990-08-23
Abstract: PURPOSE:To prevent an on-screen display from jutting out from a television screen by switching a count set value little by little with a vertical display counter responding to changeover output. CONSTITUTION:A detection circuit 7 is provided to detect whether or not the oscillation frequency of the oscillation frequency output of an oscillation circuit 6 is more than a prescribed value. The oscillation frequency of the oscillation frequency output for on-screen display from the oscillation circuit 6 is changed according to the horizontal size of a television screen 1. When this oscillation frequency is changed to be more than the prescribed value, the changeover output for the count set value is supplied against the vertical display counter from the detection circuit 7. On the other hand, when the vertical size is adjusted according to the horizontal size, since a vertical display counter 4 switches the count set value little by little according to the input of this changeover output, a vertical area detection point is adjusted to be a prescribed position at all times even when the vertical size is changed. Thus, the on-screen display can be prevented from jutting out from the television screen.

IPC: G02F1/133
Filed: 1986-09-19
Abstract: PURPOSE:To improve picture quality by nearly equalizing the electric insulation resistance of one dielectric layer to the electric insulation resistance of the other dielectric layer. CONSTITUTION:A field-effect type liquid crystal display element consists of two substrates 1 and 9 which have at least electrodes covered with dielectric layers 3 and 4 on their surfaces and a liquid crystal layer 7 held between the substrates 1 and 9, and the electric insulation resistance of one dielectric layer 3 is nearly equalized to the electric insulation resistance of the other dielectric layer 4. When the amount of charges accumulated on the dielectric layer (oriented film) 3 on one substrate of the liquid crystal display element is different from the amount of charges accumulated on the dielectric layer (oriented film) 4 on the other substrate, an effective voltage applied to the liquid crystal layer is different in level according to the polarities and causes a flicker. This liquid crystal display element is so formed that the dielectric layer (oriented film) 3 on one substrate 1 is nearly equal in resistance to the dielectric layer (oriented film) 4 on the other substrate 9 and charges are nearly equal in easiness of accumulation between the dielectric layers, so the flicker is extremely small.
