Title: Clamp circuit
Inventor: YANO TAKASHI
IPC: H04N5/18
Filed: 1994-06-29
Abstract: PURPOSE:To prevent a clamp error due to noise such as a reset pulse when an output of a CCD or the like is clamped to a prescribed potential. CONSTITUTION:Two transistors(TRs) 100, 102 are connected to a noninverting input 120 to which a signal shifted to a potential of a clamp capacitor is inputted, a TR 104 is connected to an inverting input 122 to which a reference voltage is applied and the output of a differential amplifier circuit comprising them is not balanced. The base current given to the two TRs 100, 102 are divided by a prescribed ratio and the resulting current is fed to an output side via TRs 110, 116 of a mirror circuit and a current in response to the reference voltage from the inverting side TR 104 is fed to the output side via mirror circuits 112, 124, 128, 132. Thus, an output Ix to charge/discharge a capacitor in the charging state is lower than that in the discharging and the charging of the capacitor by the intruded noise is reduced to prevent increase in the clamp level.

Title: Wire dot head
Inventor: ARA YOJI
IPC: B41J2/26
Filed: 1987-06-16
Abstract: PURPOSE:To stabilize the behavior of a movable unit made of an armature and a wire and to accelerate the speed of a recording by adding a vibration attenuating member for attenuating a vibration generated by the warpage of the armature to the armature at the time of striking.

Title: Semiconductor light emitting device
Inventor: YONEYAMA OSAMU
IPC: H01S5/00
Filed: 1988-06-15
Abstract: PURPOSE:To improve the reliability and to facilitate the maintenance for a semiconductor light emitting device by setting some of plural light emitting elements in the halt state and actuating other light emitting elements. CONSTITUTION:The laser diodes 1a and 1b having their optical axes orthogonal to each other are used together with the condenser lenses 2a and 2d which focus the laser beam LB, a polarizing plate 3, and an optical fiber 4. The diode 1a usually emits the light, thus the beam LB radiated from the diode 1a is condensed by the lens 2a and transmitted by the fiber 4 through the plate 3. While the diode 1b is kept under the halt state and does not emit the light. Thus it is possible to improve the reliability and the lifetime and to facilitate or eliminate the maintenance for a semiconductor light emitting device.

Title: Ink sheet
Inventor: MURAKAMI SADATOSHI
IPC: B41M5/392
Filed: 1986-06-27
Abstract: PURPOSE:To obtain an ink sheet having excellent antistatic property, by incorporating a antistatic surfactant into an ink layer. CONSTITUTION:An ink sheet 1A comprises a base 2 and an ink layer 3A comprising an antistatic surfactant. Since a paraffin resin is generally used as a matrix resin of an ink in many cases, it is suitable that the antistatic surfactant used in the ink layer 3A is a nonionic surfactant, from the viewpoint of compatibility with the resin. The nonionic surfactant may be, for example, a polyoxyethylene alkyl ether or a fatty acid ester of polyoxyethylene. The amount of the surfactant is 0.1-10wt% based on the ink layer 3A. The antistatic surfactant is lowly transferred to the surface of the ink layer 3A to make the surface hydrophilic. Accordingly, the electrical insulating property of the surface of the ink layer 3A is lowered through adsorption of moisture in air onto the surface of the ink layer 3A or the like, whereby static electricity is prevented from being generated on the ink layer, and static electricity, if generated, is dissipated.
