Title: Liquid jet recording head
Inventor: SEKIYA TAKURO
IPC: B41J2/075
Filed: 1988-03-12
Abstract: PURPOSE:To obtain high image quality, by providing a large number of orifices to a head vertically or at a certain angle in an array form and making the distance from an upper orifice surface to a recording medium shorter than the distance from a lower orifice surface to said recording medium. CONSTITUTION:In such a case that the number of emitting orifices constituting a multiorifice array are increased and recording quantity capable of performing recording at once is increased, when the number of emitting orifices increased too many, image quality is disturbed, because head is erected in an almost vertical direction to receive the effect of gravity and the time reaching paper is different by the difference of back pressure between the upper and lower parts of the head 1. Then, the head 1 is inclined with respect to recording paper 2 and the upper part of the head 1 is allowed to approach the recording paper 2 and the lower part thereof is made remote therefrom and the irregularity of the time reaching the surface of the paper is corrected by the difference between the emitting speeds of ink droplets generated by the difference in back pressure and high image quality can be achieved.

Title: Ball packing of gas cock
Inventor: TAKAHASHI KIYOSHI
IPC: F16K5/06
Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To smoothly operate a handle and a lever even though they are used for a long period of time. SOLUTION: When a handle is rotatively operated for switching a transfer direction of gas fluid, a ball is also rotated according to the rotation of the handle. When the ball is rotated on the grasping surface 6 of a ball packing 1, lubricating oil stopped in the small hole 7 of the grasping surface 6 is continuously supplied to an interval between this grasping surface 6 and the ball and a thin oil film layer is formed on the grasping surface 6, therefore, even though the handle is used for a long period of time, the handle is stably and smoothly operated, and also fluid gas is hardly leaked from the interval between the grasping surface 6 and the ball.

Title: Production of thin piezo-electric film

Filed: 1986-03-17
Abstract: PURPOSE:To form a thin AlN film having excellent orientation to a C-axis and small internal stress at a low temp. by heating an Si substrate of Si substrate provided with a thin SiO2 film in a vacuum then introducing gaseous Ar and N2 into a vessel and executing reactive sputtering by using an Al target. CONSTITUTION:The Si substrate or the Si substrate provided with the thin SiO2 film is put into the vessel in which the high vacuum is maintained. The substrate is heated to the relatively low temp. of about 150-250 deg.C by a heater. A high-purity gaseous mixture composed of Ar:N2=1:1 is then put into the vessel and an electric discharge by high-frequency electric power is generated between the Al target and shutter in the vacuum vessel to clean up the surface of the Al target. The shutter is then opened and the thin AlN film is sputtered and formed by the Al target on the Si substrate. The thin AlN film which is remarkably improved in the orientation to the C-axis and the internal stress in the thin film is thus stably formed.

Title: Developing device
Inventor: MATSUZAWA KUNIHIKO
IPC: G03G15/09
Filed: 1987-03-17
Abstract: PURPOSE:To permit formation of a developer to a thinner layer and to obtain a high- accuracy fine image having no uneven densities by disposing one of two stationary type blades used for a contactless two-component developing device in the developing pole position on the upper stream side of the developing region or near the developing region and impressing the voltage of the polarity reverse from the charge polarity of the developer. CONSTITUTION:The voltage of the polarity reverse from the charge polarity of the developer is impressed from a power supply 12 to the 2nd blade 5. The toner particles existing in the developer layer are induced by the electric field to appear on the layer surface when the developer is formed to the thinner layer by passing the spacing. The reason thereof lies in that the particles having the larger triboelectricity are more liable to receive the above-mehntioned effect and that the toner particle layer having the stable triboelectricity is consequently formed on the layer surface. The stable and uniform development is executed by such effect and the development efficiency is simultaneously improved. The consumption of the developer is thus advantageously reduced and the speed increased. The particles which suspend between the latent image carrier and the developing device and do not contribute to the development are attracted by the 2nd blade charged to the reverse polarity, by which the scattering of such particles is prevented.
