IPC: B65H9/14
Filed: 1982-03-10
Abstract: PURPOSE:To secure proper feeding by making the conveying distance between a pair of temporary stop adjusting rollers and a sheet feed roller a little shorter than the sheet size. CONSTITUTION:The distance between a pair of temporary stop adjusting rollers 21 and a sheet feed roller 33 to feed sheet toward them is set to be a little  shorter than or approximately equal to the size of the sheets to be conveyed.

Title: Method for treating nozzle for water repellency
Inventor: AIZAWA JUNICHI
IPC: B41J2/045
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To enable an extremely thin water-repellent film to be easily formed and thereby stabilize the discharge performance between plural nozzles by first forming a film of a surfactant on the discharge face and forming a film of a water repellent material when a nozzle with a discharge face having an opening for discharging liquid is treated for water repellency. SOLUTION: A nozzle 2 has the inner face 201 of a nozzle plate 1 and an opening 202 which is exposed on the discharge face 101 of the nozzle plate 1, communicating with the inner face 201. The opening 202 has an edge 203 where the discharge face 101 converges with the inner face 201. The ink to be discharged is discharged from the discharge face 101, passing through the opening 202 from a space encircled by the inner face 201. In this case, a film 3 of a surfactant is formed on the discharge face 101, but when the film 3 is formed, first the surfactant is applied on the discharge face 101 and then is dried. Next a water repellency material 401 is applied, for example, by atomization to the discharge face 101. Thus it is possible to stabilize the discharge performance of the ink.

Abstract: PURPOSE:To attain a higher printing density, by a method wherein of a stainless steel plate provided with grooves and a smooth stainless plate jointed to the stainless steel plate, at least the parts corresponding to a compression chamber are jointed by diffusion bonding of metals. CONSTITUTION:A photoresist film 41 is provided on a specularfinished metallic substrate 40 by coating, and is exposed to light in a desired pattern, followed by leaving only a required part of the film 41 while removing the other parts of the film 41. Next, the substrate is etched at parts where the photoresist is absent, thereby forming recessed parts (ink jet nozzle parts) 43, and the photoresist is completely removed to obtain a lower substrate. Then, bonding surfaces of the lower substrate 40 and a specular-finished metallic upper substrate 42 are matched with each other, and diffusion bonding is effected by heating under a gas pressure, whereby molecular diffusion of metals is caused, and the metals are bonded to each other without being melted, so that an objective head can be produced without loss of the ink jet nozzle parts 43. For example, substrates 61, 63 and a thin sheet 62 set therebetween are bonded to each other by diffusion bonding, and piezoelectric elements 64a-64d are mounted on the substrates 61, 63 at parts corresponding to compression chambers communicating with nozzles.

Title: Cooling method of cut metallic sheet
Inventor: IMAMURA JIYUNICHI
IPC: B05B13/02
Filed: 1982-03-12
Abstract: PURPOSE:To increase a cooling efficiency and to increase the productivity of a painted sheet etc. by providing many spray nozzles across the running passage of a heated cut metallic sheet and increasing the jetting amount etc. of the cooling water toward the downstream from the upstream. CONSTITUTION:The cut metallic sheet 16 immediately after painting, heating and drying enters a cooling chamber, runs on rolls 22 and is cooled rapidly by receiving the jets 38 of cooling water from spray nozzles 24 at the upper and lower surfaces. The particles, density and amount of the jet are controlled so that they are increased successively from the nozzles 24 of the upstream side to that of the downstream side. This control is performed by the control of the opening degree of valves 28, the selection of the nozzles 24 and the arrangement of a water supplying pipe 40 etc. Thereby, since the metallic sheet can be cooled slowly and also rapidly, the strain generation accompanied with the rapid cooling can be decreased.
