Title: Recording, reproducing and erasing method for magneto-optical recording medium and apparatus for the same
Inventor: ORUKAWA MASAHIRO
IPC: G11B11/105
Filed: 1990-10-30
Abstract: PURPOSE:To curtail the time required for a series of recording operation including erasing, recording, recognition and reproducing operation by inverting bias magnetic field only immediately before the recording operation and immediately after starting the recognition and reproducing operation and by always applying the magnetic field in the erasing direction during the reproducing operation.

Title: Inkjet head
Inventor: KITAHARA TSUYOSHI
IPC: B41J2/015
Filed: 1988-11-21
Abstract: PURPOSE:To offer an inkjet head at a low cost which is stable in discharging ink drops by providing a nozzle forming member connected to a box body and having at least one or more nozzle openings and, a pressure generating means for generating a pressure assuring flying as ink drops, wherein said box body and nozzle forming member is connected such that a tension is applied to said nozzle forming member. CONSTITUTION:When a selective electric signal is applied to a vibrator 24, a piezoelectric element shrinks by the piezoelectric effect, whereas a foil member which is high in rigidity is restricted to change its size. Accordingly, the vibrator is deformed and shifted to the eide of a nozzle plate 21, whereby a pressure is generated at a very small gap between the vibrator 24 and nozzle plate 21. Consequently, ink drops are discharged by the pressure. Since the nozzle plate 21 and a box member 20 which have been connected each other at a temperature lower than the operating temperature tend to restrict the deformation of the box body 20 and to spread out respectively at the operating temperature, a tension acts on the nozzle plate 21. As a result, the distortion of the nozzle plate 21 when it is a single component is absorbed by the tension, so that the nozzle plate becomes favorably flat.

IPC: G02B6/26
Filed: 1988-11-24
Abstract: PURPOSE:To enable wavelength multiplex transmission as well as multiple fiber constitution by using an achromatic prism which compensates a chromatic aberration as a trapezoidal prism which rotates. CONSTITUTION:The achromatic trapezoidal prism 12 is constituted as a trapezoidal prism which has a diameter (s), a length l, and a base angle phi1 and consists of an incidence surface 12a, a projection surface 12e, and a base 12c by sticking trapezium prisms 14a and 14b on both slanting sticking surfaces 12b and 12d of an isosceles triangular prism 13 which has a base angle phi2 and a base l. Here, when light having wavelength lambda2 longer than wavelength lambda1 is incident on the achromatic trapezoidal prism 12 from left, the light is refracted by the incidence surface 12a more than lambda1, but the spread between optical paths is corrected by the 1st sticking surface 12b and the light is projected on the same optical path with the light with the wavelength lambda1. Consequently, the same projection light is obtained from the same incident light and the loss of wavelength multiplex transmission is suppressed.
