Title: Original plate for lithography
Inventor: HASEGAWA SATORU
IPC: B41C1/10
Filed: 1986-04-23
Abstract: PURPOSE:To obtain a printing area having high printing resistance and high sensitivity and a stain-free non-image area by coating a hydrophilic support with a layer contg. a hydrophilic binder and microcapsules contg. a photopolymerizable monomer and/or a photosensitive resin and having lipophilic wall films. CONSTITUTION:When a layer contg. microcapsules contg. a photopolymerizable monomer and/or a photosensitive resin is patternwise exposed, the microcapsules in the exposed part harden, so the softening, bonding, melting and breaking of the walls of the microcapsules and the release of the contents are not caused even by heating or pressing. The microcapsules in the unexposed part are stable during ordinary handling and under ordinary conditions. When the walls of the microcapsules are softened, bonded and melted by heating, the walls and/or the contents mix and form lipophilic uniform film. when the walls of the microcapsules are broken by pressing, the contents mix and form a lipophilic uniform film.

Filed: 1981-06-19
Abstract: PURPOSE:To make the bias to a detection transistor(TR) stable, by using a base- emitter voltage of the 1st stage TR, an offset voltage at a negative feedback circuit as a bias voltage to the detection TR. CONSTITUTION:A constant current I01 flows to TRs Q24 and Q25. Further, to a TRQ23, a constant current specified with a constant voltage substracting a constant voltage (I01.R20) across the resistor R20 from a base-emitter voltage VBEQ24 of the TRQ24 based on said constant current I01 flows. The constant current flowing to the TRQ23 flows to TRs Q21 and Q22 with a share in connection with the emitter area ratio. Thus, a current i3 flowing to a negative feedback resistor R1 being the bias current of the 1st stage TRQ20 is a specified constant current. Then, an emitter potential of an output TRQ26 to a DC bias voltage Vref at an input terminal VIN is the voltage (VBEQ20+i3'.R1) which is the sum of the base-emitter voltage VBEQ20 of the TRQ20 and the voltage drop of the resistor R1. The bias voltage to a detection TRQ27 can be made by using the emitter potential.

Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To efficiently obtain a large detection signal by juxtaposing an excitation electrode and a detection electrode in a same distance on one leg of tuning fork type oscillators at least making the neighborhood of the slide edge of a leg part as a starting point, and performing excitation and detection in the neighborhood of the slide edge where distortion is the largest. SOLUTION: A first excitation electrode 5 and a first detection electrode 7 are juxtaposed in a same distance making the neighborhood of the slide edge of a leg part 4-1 of a crystal oscillator as a starting point. A second excitation electrode 6 and a second detection electrode 8 are juxtaposed in a same distance making the neighborhood of the side edge of a leg part 4-2 as a starting point. Then, the leg parts 4-1 and 4-2 vibrate right and left when applying an alternating voltage. When a turning angle velocity acts around the direction of the expansion and contraction, the Coriolis force produces a vibrational component in the orthogonal direction, and voltage signal is obtained corresponding to the Coriolis force, and the signal value makes it possible tow know a size of the turning angle velocity acting around the direction of the expansion and the contraction by the size.  Since the electrodes 5 and 6 are formed near the slide edge, a detection signal is obtained in a sufficient size.
