Title: Ink jet recording apparatus
Inventor: KASAHARA MASATOSHI
IPC: B41J2/175
Filed: 1986-02-05
Abstract: PURPOSE:To improve processing and assembling works and to obtain high filtering capacity, by forming a porous member having an engaging hole and tightly engaging an ink supply tube with said engaging hole to connect both of the filter and said tube. CONSTITUTION:A filter 16 comprises a porous member molded using a sintered alloy material or a porous resin material and a bottomed engaging hole 16a is provided to the filter 16 at the time of molding and an ink supply tube 15 is tightly engaged with said hole 16a to be connected to the filter 16. When an electric pulse is applied to a piezoelectric element 10 from an information signal source 19, the piezoelectric element 10 is deformed to reduce the volume of a nozzle pipe 11 and ink particles 6 are injected from a nozzle orifice 13. When the volume in the nozzle pipe 11 is restored, the internal pressure of the nozzle pipe 11 becomes negative to introduce the ink 17 in an ink chamber 14 into the in supply tube 15 through the filter 16 and the nozzle pipe 11 is replenished with the ink 17 but, because the introduction of the ink 17 is performed from the wide outer peripheral surface of the filter 16 toward the bottom part of the engaging hole 16a through the open pores in the filter 16, a filtering area becomes wide and ink passing resistance is reduced and high filtering capacity is obtained.

The valve 9 is then opened and the internal fluid flows toward a branch pipe 8 when the piston approaches the buffer mechanism. The rapid shut off of the internal flow upon sudden stop of the piston is, therefore, obviated ad the generation of the water hammer load is prevented.

Abstract: PURPOSE:To obtain a laser oscillator which is excellent in oscillation wavelength stability and can be easily used at an ordinary industrial level by automatically performing the line tuning to be performed by adjusting the grating of a resonator without making any highly precise manual adjustment. CONSTITUTION:This laser oscillator is provided with a wavelength measuring grating 13 which branches part 8a of the laser light beam emitted from the output mirror 7 of a resonator, detector 15 for detecting the branched light, and arithmetic processing means 17 which inputs signals from the detector 15 through an A/D converter 16 and processes the input signals for judging the presence/absence of a shift in oscillation wavelength.

Title: Temperature sensor
Inventor: ITO SUSUMU
IPC: G01K7/16
Filed: 1988-02-02
Abstract: PURPOSE:To detect temperature without requiring any special circuit by forming at least one of a couple of supporting members which contact and leave each other by using an elastic piece. CONSTITUTION:When the couple of supporting members 12 and 14 are so formed that they contact each other when a superconductor 26 is above its critical temperature, the superconductor 26 enters a superconducting state below the critical temperature. Consequently, the repulsive force based on Meissner effect operates between a magnet 30 provided opposite the superconductor 26 and the superconductor 26 to separate both members 12 and 14, and the critical temperature can be detected. Further, the superconductor 26 is arranged between the couple of members 12 and 14 and the magnet 30 is provided behind the superconductor 26 to make the members 12 and 14 leave each other below the critical temperature of the superconductor 26; when the superconductor 26 drops below the critical temperature, its superconducting state is lost and the magnetic flux of the magnet 30 is transmitted through the superconductor, so an attractive force operates between both magnets to bring the members 12 and 14 into contact with each other, so the critical temperature can be detected. Then the couple of members 12 and 14 contact and leave each other repeatedly about any critical temperature in any case.
