Abstract: PURPOSE:To obtain a high-quality recorded condition, by fitting an elastic tube to the outer peripheral surface of a liquid passage at a position where a cylindrical-type piezoelectric vibrator is not present. CONSTITUTION:The elastic tube 5 is externally fitted to the liquid passage 2 in a liquid jet recording head, and is positioned at a part where the cylindrical- type piezoelectric vibrator 1 is not fitted (on the outside of a filter 3).

Title: Pilot type solenoid-controlled valve
Inventor: KOBAYASHI AKIYUKI
IPC: F16K31/42
Filed: 1985-03-26
Abstract: PURPOSE:To prevent shock given to a main valve body and make it possible to form the main valve body of single nonmetal material by making fluid flowing into a pilot valve hole perform buffer and stopping actions for the main valve body. CONSTITUTION:When a movable iron core 17 rises, an outlet flow rate from a pilot valve hole 19 to an outlet 3 becomes larger than an inlet flow rate from a bleed hole 21 to a back chamber 20. Consequently, pressure in the back chamber 20 lowers, and the pressure of fluid flowing into an inlet raises a main valve body 16 to open a main valve hole 4. The main valve body 16 approaches the lower surface of the movable iron core 17, hence the valve seat 22 of the pilot valve hole 19 also approaches there to reduce a gap G between the lower surface and the valve seat. Thus a flow rate passing through the pilot valve hole 19 decreases, and the inlet flow rate from the bleed hole 21 to the back chamber 20 increases relatively. When the main valve body 16 is pressed down, the pressure in the back chamber 20 lowers to approach the movable iron core 17 to the main valve body 16 again. The repetition of the above actions stabilizes the outlet flow rate from the pilot valve hole 19, the inlet flow rate into the back chamber 20, pressure around the main valve body 16 and its dead weight in a mutually balanced state to keep the main valve hole 4 opening.

Title: Magnetostatic wave resonator
Inventor: ASAO HIDEKI
IPC: H01P7/00
Filed: 1988-03-14
Abstract: PURPOSE:To suppress the harmonic mode resonance by using a strip conductor having a width over the wavelength of the harmonic mode of the minimum order for a transducer. CONSTITUTION:A strip conductor 9 is arranged along the X axis being a center axis of a rectangular ferromagnetic substance thin film 1 and has a width being nearly 1/3 of the width of the ferromagnetic substance thin film 1. Since the wide strip conductor 9 is placed in the center, the mode being in odd symmetry is not excited, and the fundamental mode being an even symmetry as shown in broken lines and the harmonic modes of even symmetry shown in solid lines and onedashed chain lines are excited. In such a case, since the transducer of the strip conductor width where the coupling is made loose to all the harmonic codes and the coupling is made close only to the fundamental mode is employed in such a case, the harmonic mode resonance is suppressed.

Abstract: PURPOSE: To accelerate cooling of a burner head and to enable to perform a steady combustion at an inexpensive cost, by a method wherein a separator is positioned upright in a burner head of a petroleum gasification combustor, and a primary air path and a mixture gas path are formed to separate a primary air from mixture gas.  
     CONSTITUTION: Primary air A for combustion flows through an air hole 4a, and part thereof branches in the direction of an arrow mark B through a lower part of an agitating plate 4 at a place where a conical cap 5 is located. Meanwhile, petroleum is fed to the conical cap 5 through a pipe 6, and is sprayed to a gasification wall 8, heated by a heater 7, through the centrigual force for gasification. So gasified fuel is mixed with primary air B which is caused to branch, and the mixture is jetted through a rectifying hole 9a in a separator 9 to a burner flame hole 10a for ignition to form a flame 15. Meanwhile, primary air 4a passes through the left side of the separator 9 and is jetted through a primary air jet hole 10b to help combustion. This accelerates cooling of a burner head 10 and enables to perform a steady combustion at an inexpensive cost.

CONSTITUTION:Several metallic plates 2, 2... to which through-holes 5 are formed are superposed through prepregs 3, 3... while circuit-boards 6 are stacked onto the outside surfaces of the metallic plates as outermost layers through prepregs. The stack is heated and pressure-molded, a resin impregnated to the prepregs is cured, and each metallic plate and internal-layer circuit-boards 12 are laminated and cemented alternately while the circuit-boards are laminated and bonded onto the outside surfaces of the metallic plates as the outermost layers. The resin infiltrated in the prepregs is made to flow and filled into respective through-hole in the metallic plates and cured at the same time. The greater part of the resin contained in the prepregs laminated on the outsides of the metallic plates as the outermost layers flows into the through- holes in the metallic plates, but indentations in the sections of the through-holes in the metallic plates do not appear on the surfaces because the circuit-boards having rigidity are laminated on the outside surfaces.

Title: Recording and reproducing device
Inventor: ABE HIROYUKI
IPC: G11B17/32
Filed: 1987-03-17
Abstract: PURPOSE:To prevent the deformation of a recording medium at the time when the traveling of the recording medium is stopped by providing a through hole for passing air stream to downstream side in the traveling direction of the recording medium between the outside and recessed parts of a padding member. CONSTITUTION:A recording medium 15 is located at the position shown by a continuous line separated from a pad 11 at the traveling stoppage time of the recording medium. When the recording medium 15 starts its traveling, the air inside a recessed part 14 flows out to the external part through a through hole 16 by being dragged by the recording medium. Namely negative pressure is generated inside the diffused (expansion) rapidly and the recording medium is attracted to the pad 11 as shown by double dotted chain line. When the recording medium 15 stops the traveling, the air flows into the recessed part 14 through the through hole 16 and the negative pressure inside the recessed part 14 is eliminated to separate the recording medium 15 from the upper face of the pad 11. Normal recording and reproducing are thus effected at all times and the strain of the recording medium 15 is eliminated, as well at the traveling stoppage time.
