Title: Fluid oscillating device
Inventor: TAKAHASHI YUTAKA
IPC: F15D1/08
Filed: 1984-07-31
Abstract: PURPOSE:To obtain easy selection of the jet pattern from oscillating jet and non- oscillating jet by providing a bypassing port on a side wall of a fluid passage and a control chamber having a control port communicating to the atmosphere on the other side wall thereof. CONSTITUTION:The liquid flowing from a main passage pipe 16 to a supply passage 18 is injected through a supply nozzle 19. When a control signal pipe 17 is open, both of a bypassing port 24 and a control port 26 are communicated to the atmosphere and atmospheric flows Fa1 and Fb1 are generated, and the jet F1 from the supply nozzle 19 has on both sides thereof the pressure equal to the atmospheric pressure, flowing straightly. On the other hand, when the control signal port 17 is closed, an atmospheric flow Fa2 through the bypassing port 24 is generated to make the pressure at the wall side 20 equal to the atmospheric pressure, but the pressure on the side adjacent to the control chamber 25 becomes below the atmospheric pressure. As the result, the jet F2 from the supply nozzle 19 is deflected toward the side wall 21. Thereafter, when the reflux Fc1 has increased the pressure in the control chamber 25, the jet F2 flows straightly.

Title: Ink jet head
Inventor: FURUKAWA TATSUYA
IPC: B41J2/195
Filed: 1980-11-19
Abstract: PURPOSE:To keep the temperature of ink inside a liquid chamber constant for obtaining uniform ink droplets all the time by altering the effective value of voltage to be applied on an electrostrictive vibrator according to the temperature of ink. CONSTITUTION:When the temperature of ink is low, because the difference between the output of A/D converter 9 and a set value is great, the output of the converter 11 becomes great. DC voltage from the D/A converter 11 is overlapped with AC voltage from an AC-generating circuit 12 at an overlap circuit 13, and voltage to be applied to the electrostrictive vibrator 3 becomes great. For this reason, the heating amount of the electrostrictive vibrator 3 is increased and the temperature of ink in a liquid chamber 6 is thus raised. As the temperature of ink rises, the output of the D/A converter is lowered, whereby voltage to be applied to the electrostrictive vibrator 3 is smaller in its effective value to lessen the heating amount of the vibrator 3. In this way, the temperature of ink in the liquid chamber 6 can be kept constant.

Title: Decorative shrinkable film fitting
Inventor: YAMADA SHIGEKI
IPC: B41M1/30
Filed: 1984-07-30
Abstract: PURPOSE:To obtain three-dimensional fitting with metallic gloss by printing an optionally selected pattern on the upper surface of a thin metal layer using an ink composed mainly of cold or ultraviolet ray-curing resin and fixing the curing resin-applied portion and roughing the other shrinking portion of the thin metal layer, thus forming a relief pattern of the fixed portion, during thermoshrinking process. CONSTITUTION:A decorative shrinkable film skin 1 composed of a thermoshrinking base film 2 with a desired pattern printed using curing-type resin ink is formed in a cylindrical form so that it may be wound around the barrel 11 of a vessel, etc. If the film 2 is thermally shrunk, a cured layer 4 printed using a curing-type resin ink is fixed as it is. The base film 2 representing an unprinted portion thermally shrinks, sticking to the barrel 11 of a vessel 10. The patterned portion 4 printed using a curing-type resin ink is kept tense through the base film, so that it looks like a mirror surface and the other portion has a rough surface. Subsequently, the gloss differs because of irregular reflection, giving a relief pattern vividly.

Filed: 1995-06-28
Abstract: PURPOSE: To save power consumption by holding a plunger at a first position through a holding means after the plunger is shifted to the first position through current carrying to a first coil, and dispensing with current carrying to each coil after completion of shifting of the plunger to the first or second position. CONSTITUTION: A flow passage 15a is opened when a plunger 17 is at a second position without current carrying to coils 13, 14. When current is carried to the coil 13 by means of a driving circuit from such a state, electromagnetic force is generated on the coil 13 and the plunger 17 is attracted to a first position. When the electromagnetic force applied for shifting the plunger 17 to the first position is larger than spring force of a movable member 20a, the plunger 17 is moved upward, and the movable member 20a is under flexure outward with respect to a shaft of the plunger 17. When the plunger 17 is on the side of the first position, the spring force of the movable member 20a is applied in the direction for shifting the plunger 17 to the first position. The plunger 17 then reaches the first position and is held there.

Abstract: PURPOSE: To form comparatively gentle inclination on the surface of a spacer of insulating material, and enable forming the next layer on a step-difference and an edge, with comparatively gentle inclination and sharpness, by a method wherein an overhanging part selectively formed on the edge of an isolation region masks the lower insulating material, during anisotropie stching. CONSTITUTION: An adjacent edge 20 of a part 31 of insulating material overhangs the lower insulating material 30 formed on the surface 1a in such a manner that an insulating layer 3 is selectively formed on the edge 20 of an isolation region 2. During anisotropic etching of insulating material, insulating material 32 formed on the surface is masked at first by the overhanging part 31. When a gap 34 is once opened, anisotropic etching of the lower insulating material 32 is begun. As the gap 34 between the overhanging parts 31 becomes larger, the region of the part 32 of the insulating layer which is exposed to the anisotropic etching increases. These two effects are combined, and a surface 37 having comparatively gentle inclination is formed on a spacer 30 left on the side wall 2b of the electrically conductive region 2.
