Title: Ink jet recorder
Inventor: TSUDA YUKIFUMI
IPC: B41J2/015
Filed: 1982-02-03
Abstract: PURPOSE:To improve the stability and reliability of a recording unit by such an arrangement wherein an ink current is accelerated and stabilized by causing it to fly together with air current supplied from an air supply source, by this arrangement, the rise time and fall time of air pressure at the time of starting and stopping of the air supply source are made to be variable. CONSTITUTION:By closing an air control switch 26, the output of a standard power source 25 is inputted into an integration circuit 27 through the switch 26. As its output generates a certain time delay for the input, the rise and fall of the circuit become dilatory. Since such rise and fall characteristics are determined by the time constant of the integration circuit 27, for example, a variable resistor is used as a resistor, and by this, desired rise and fall characteristics can be realized by adjusting the time constant of the integration circuit 27 through the regulation of the variable resistor. A motor drive circuit 28 amplifies the output of the integration circuit 27 for driving a DC motor 24. Since the rise and fall characteristics of the DC motor can be controlled by varying the time constant of the integration circuit 27, by driving an air pump of an air supply source, the rise and fall characteristics of its pressure at the time of starting and stopping can be controlled.

Title: Cold cathode element
Inventor: IWASA TAKASHI
IPC: H01J9/02
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To make adequate electrons emitted with a low applied voltage for enhancing practical usability by constituting a cold cathode element of a diamond-like carbon film, in which the half width value of photoelectric spectrum of C1 S electrons by X-ray photoelectron spectral analysis is within a specified range. SOLUTION: This cold cathode element is formed of a diamond-like carbon film, in which the half width value HW of photoelectric spectrum of C1 S electron by X-ray photoelectric spectral analysis is HW>=1.72 eV. That is, the diamond property or electrical insulating property in the carbon film is weakened, while the graphite property or conductivity is enhanced. Thus, since the emission field of the cold cathode element is reduced, electrons can be emitted adequately even with a low applied voltage. The diamond-like carbon film is formed by ion beam evaporation or the like. According to this method, since the evaporation energy is controllable, the density in the carbon film can be increased, and for this reason preferably a negative ion beam is used.

Title: El panel
Inventor: NAKAMURA MITSUO
IPC: H05B33/14
Filed: 1989-01-26
Abstract: PURPOSE:To always enable the emission having a high luminance by forming the distributed inclusion condition of the fluorescent particles and the fluorescent pigment in an illuminant layer so that the closer to a transference electrode layer, the higher the ratio of the fluorescent pigment, and the closer to a back plate layer, the higher the ratio of the fluorescent particle. CONSTITUTION:The distributed inclusion condition of the fluorescent particles 3a and the fluorescent pigment 3b such as ZnS in an illuminant layer 2 is formed so that the closer to a transference electrode layer 1, the higher the ratio of the fluorescent pigment 3b. On the other hand, the closer to a back plate layer 5 (an insulating material layer 4 side), the higher the ratio of the fluorescent particle 3a. It is formed in the two-layers type structure. Even if the fair quantity to be distributed and included in the illuminant layer is reduced, the required luminescent complementary colors and the dimming function are kept to show sufficiently for a long time because of the structure that the fluorescent pigment is concentrated to the lighting surface and laminatedly located. Further, attending on the wholly reduction of the inclusion ratio of the fluorescent pigment in the illuminant layer, the absorption of the light emitted from the fluorescent particle is reduced and restrained to eliminate the lower of the luminance.
