IPC: B41J2/135
Filed: 1994-04-26
Abstract: PURPOSE:To enhance the directionality at the time of the emission of ink in an ink jet head having nozzles substantially crossing ink passages at a right angle. CONSTITUTION:A middle plate 3 is bonded to a nozzle plate 2 having a plurality of ink passages 5 carved therein in a surface direction. The nozzles 6 vertically communicating with the end parts of the nozzle passages 5 are provided to the nozzle plate 2 in the plate thickness direction thereof and spiral grooves (uneven parts) 6a are provided to the inner walls of the nozzles 6. When ink reaches the nozzles 6 through the ink passages 5 by the pressure generated in a pressure chamber 5a accompanied by the deformation of the piezoelectric elements 7a due to the driving of a pressure means 7, ink is guided within the nozzles 6 by the grooves 6a to produce ink flow going toward the tips of the nozzles. A vortex is produced having the center line of each of the nozzles 6 as a rotary axis by the spiral flow of ink and an ink droplet high in straight advance properties is emitted at high speed.

Filed: 1989-04-07
Abstract: PURPOSE:To record an image of satisfactory exposure by matching the exposure to a specific luminance to perform exposure and matching the exposure to another luminance to perform exposure in the case of an object having a large luminance difference and recording both images. CONSTITUTION:When a release switch 8 is depressed, photometry is started, and the brightness of the object is converted into an electric signal by a multidivided photometric element 13 and is amplified by an amplifier 14 and is applied to a CPU 9 as a photometric value.

Title: Optical recording and reproducing device
Inventor: NAKAMURA TOORU
IPC: G11B7/13
Filed: 1984-05-04
Abstract: PURPOSE:To attain the reproduction of a photomagnetic disk or a disk where the information is recorded with recesses/projections or variation of reflection factors, by rotating the polarizing direction of the reflected light separated by a half mirror by 45 deg. to obtain the separated polarization components orthogonal to each other. CONSTITUTION:When a photomagnetic disk is used to an information recording medium 5, an equal amplitude is obtained between the transmitted light and the reflected light of a polarized beam splitter 14. Thus the signal beams containing information phases are opposite to each other. Then said transmitted light and reflected light are converted into electric signals to obtain a difference between them. Thus the in-phase components are offset to each other, and the information components of phases opposite to each other are magnified double to obtain a reproduction signal having a high S/N. In the case of a disk where the information is recorded with recesses/projections or variation of reflection factors, the reflected light undergoes modulation of intensity and the information signal light made incident on the two-split and four-split detectors 15 and 18 have the same phase and an equal amplitude. Thus the highly efficient reproduction is possible by adding the output of an adder 22 of electric signals detected by the detector 15 and that of the electric signals detected by the detector 18 by an adder 24.
