Title: Solid lubrication bearing
Inventor: IMAI TERUAKI
IPC: F16C33/66
Filed: 1988-02-22
Abstract: PURPOSE:To obtain a solid lubrication bearing having long service life and low friction torque by forming a hard surface layer on the contact surface of a bearing component part by an N-ion implantation process, and by forming thereon a lubricating film made from a soft metal or layered solid lubricants. CONSTITUTION:An N-ion implantation layer 4 harder than a layer by a conventional thermo-hardening process is formed at nearly normal temperature on the contact surfaces of a disc sample 1 and a ball 2 in bearing component parts, and thereon a film made from a soft metal or layers of solid lubricants 3 is formed. A longer life bearing with smaller frictional resistance can thus be obtained, compared with a bearing formed with the same lubricating film on the conventional thermo-hardened contact surface. Moreover as the N-ion implantation can be performed at nearly normal temperature, residual stress or thermal deformation can be restrained, compared with the case of conventional thermo-hardening process.

Title: Apparatus for conveying fluid under pressure
Inventor: HAYASHI TAKESHI
IPC: F04B9/08
Filed: 1981-03-20
Abstract: PURPOSE:To prevent acting of an excessive force to a piston in an apparatus for conveying a highly viscous fluid like ready-mixed concrete under high pressure, by dividing the inner space of a cylinder into a chamber for a fluid to be conveyed and a chamber for a driving liquid. CONSTITUTION:When liquid is forced into a cylinder 3 by a liquid pump 7, a piston 6 is urged by the liquid to force out a substance to be conveyed that has been introduced into a chamber 4 for the substance to be conveyed. That is, since the piston 6 is acted at one side thereof by pressure of the substance to be conveyed in the chamber 4 and at the other side by pressure of liquid in a driving liquid chamber and the above two pressure are almost equal to each other, differential pressure acting on the piston is considerably small, so that no excessive local load does not act on the piston 6. Further, since pressure in the chamber 5 is increased with increasing of the discharge pressure of the pump, differential pressure acting on the piston 6 is not changed substantially even if the discharge pressure of the pump is increased considerably.

Title: Ink jet head
Inventor: KANAYAMA YOSHIO
IPC: B41J2/055
Filed: 1989-02-20
Abstract: PURPOSE:To obtain an ink jet head capable of jetting ink drops with enough jet force by a method wherein a vibration wall of a pressure chamber is displaced by Lorentz's force by making a record signal current flow through a current part to jet the ink drop from a nozzle. CONSTITUTION:An ink jet head equipped with a pressure chamber block 11a. When a current i is made to flow according to a recording signal, a thin wall 15a of a pressure chamber 12a receives Lorentz's force to be distorted in a direction of reducing volume, and an ink drop is jetted from a nozzle 17a. However, since the current is made to flow through a conductor 14a outside the pressure chamber 12a, the current neither electrolyzes ink nor generates any bubble due to Joule heat. Further, since jetting force of the ink drop can be intensified by increasing any one of a magnetic flux density B, the number of the conductors, the current i, and a length of the thin wall 15a, enough jetting force of the ink drop can be obtained. Therefore, the ink drop can be jetted with enough force according to the recording signal neither by electrolyzing the ink nor by generating any bubble in the ink due to Joule heat.

Abstract: PURPOSE:To provide recrystallized thin films whose plane orientations are aligned, without resulting grain boundaries or cracks in island areas, by forming narrower portions with a specific shape in a belt-shape semiconductor thin film. CONSTITUTION:An SiO2 film 2 and a polycrystalline silicon layer are coated on a quartz plate 1.

Next, an SiO2 layer 7 is deposited thereon to form a silicon substrate 8. On the silicon substrate 8 the laser beams are scanned to recrystallize polycrystalline silicon thin films. In this way, in the island areas 6, single crystal silicon thin films whose plane orientations are aligned and which do not result in cracks are formed.

CONSTITUTION:When a fixing operation is started, a film 2 is rotated and travelled by a driving roller 3, power is simultaneously started to be given to a hear generating layer 13, and after a temperature at which fixing is possible is detected by a temperature detecting element 14, a transfer material 10 having a toner image is moved in a synchronization with the film 2 and a roller 5 passing under a heating body 1, the toner image is made soft upon receiving thermal energy mainly from the heat generating layer 13 and fixed on the transfer material 10. Then, the transfer material is separated from the film 2 and the roller 5 and ejected out of a machine by a pair of paper ejecting rollers 7 and 8. After all transfer materials are ejected, power supply to the heat generating layer 13 is stopped, the film 2 is rotated for a while, that is, postrotated, the driving roller 3 is stopped and returned to an original static state and postroration time is changed in accordance with temperature detected by the temperature detecting element 14 when postrotation is started.
