摘要： PROBLEM TO BE SOLVED: To execute atomizing action in a short time and to uniformly coat image recording material with solvent for forming an image. SOLUTION: Sealing plates 328 are arranged at the right and left ends of a nozzle plate 322 positioned in the longitudinal direction of a nozzle train formed of nozzle holes 324, and an annular pipe-like supply and discharge tube 360 is formed on the sealing plate 328. The inner wall surface of the tube 360 is circularly formed to have the same inside diameter as the solvent storage space of a spraying tank 312. Namely, one end side of the tube 360 is coupled with the end along the axial direction of the tank 312 having an inner wall surface formed to be cylindrical in a state where the inner wall surface of the tank 312 and the inner wall surface of the tube 360 are smoothly connected.

摘要： PROBLEM TO BE SOLVED: To provide a liquid jetting device that can apply a solvent for image formation uniformly over an image recording material. SOLUTION: A lever mechanism consists of a piezoelectric element 326, a lever plate 320, and a support part 312B, and an elastic member 352 is filled between a couple of lever plates 320 and a couple of tank main body constitution materials 312A. A nearly rectangularly sectioned space is formed between the tips of the lever plates 320 and a solvent storage space 316 for storing water is arranged in the said space. This space is charged with an elastic member 354 so that a smooth free curve having no unevenness is drawn, thereby forming the internal wall surface of the solvent storage space 316. A surface adhesive 356 is filled so as to slightly project from a couple of recessed parts 318 constituting a part of the solvent storage space 316 and the internal wall surface of the solvent storage space 316 which stores the water with the smoothly curved surface is formed of the surface adhesive 356 and elastic member 354.

摘要： PURPOSE: To uniformly apply a small amt. of a liquid to a material to be coated collectively and linearly by providing an actuator displacing the nozzle plate connected to one end part of a displacement transmitting member so as to pressurize the liquid in a pressure chamber and ejecting the filled liquid from a nozzle orifice. CONSTITUTION: Af first, upper and lower valves 350, 352 are opened by a controller 360 and a tank valve 354 is closed and the water of a pool tank 314 is supplied through a pipe 316 to fill a jet tank 312 with water. When water is ejected, voltage is applied from the power supply controlled by the controller 360 to deform all of piezoelectric elements 326 so as to extend them at the same time. Whereupon, displacement is transmitted to a nozzle plate 322 through the revolution around the support parts 318 of a pair of lever plates 320 and the nozzle plate 322 is displaced so as to pressurize the water in the jet tank 312. As a result, the water charged into the jet tank 312 is ejected from the nozzle orifice 324 to be bonded to the potosensitive material 16 during feed.

摘要： PURPOSE:To speedily, accurately, stably and reliably record and reproduce information by providing a switching means which sets a focus servo loop to a closed loop only when the recording and reproducing area of an optical recording medium is irradiated with a light. CONSTITUTION:An information recording and reproducing part 1 is provided with an objective lens driving means 7, a holding member 9 for fixedly providing a transmitted light detector 8 to the recording and reproducing part 1 or the like. Besides, it is provided with the switching means which sets the focus servo loop consisting of a focus error signal detection means, a focus control means and the objective lens driving means to the closed loop only when the recording and reproducing area of the optical recording medium is irradiated with the light. In such a case, since the optical recording medium is placed and rotated on a turntable, it is enough that an optical system for irradiating the optical recording medium with the light is fixed. Thus, the information is speedily and accurately recorded and reproduced on the sample of the card- like optical recording medium.

摘要： PURPOSE:To improve the resolving power of reproduction signals by forming the long pits having the pit length of >=2 times the length of the shortest pits by the continuation of the shortest pits. CONSTITUTION:Pits 31, 32 are short pits and the long pits 33, 34 sandwiched by the pits 31, 32 are formed by continuing the two short pits. The signal waveforms in the case of reproduction of such pits are surely detected as an H level as the reproduction signals corresponding to not only the land part between the short pits 31, 32 and the long pits 33, 34 but also the land parts between the long pits 33 and 34 exceed a threshold level 35. The signal pits on a master disk 11 are formed by adding the optical modulation signals of prescribed square wave signals to an AO modulator 15 and exposing and developing a photoresist 12. The square wave pulses for forming the long pits are the connection of the square wave pulses for forming the short pits. The long pits 33, 34 are surely detected as the two signal pits and the resolving power of the signal pits is improved.
