IPC: B41J2/195
Filed: 1980-09-12
Abstract: PURPOSE:To provide a method of supplying fresh liquid in ink jet recording wherein the value of the amount of reduced ink in a cycle system of an ink jet recorder minus the amount of ink used in recording is defined as the amount of evaporated solvent, and the corresponding amount of solvent is supplemented to the ink in the cycle system to keep the viscosity of the ink constant. CONSTITUTION:Time is counted from the previous supplement of ink, and when the counted value has reached a prescried value, the amount of reduced ink Vrd in the cycle system is measured, the mount of ink used in recording Vis is culculated by multiplying the number of charged ink particles by an average volume of one ink particle, and the amount of evaporated solvent Vds is found from the equation Vrd=Vis+Vds to supplement the solvent together with fresh ink. In this case, at least an average value of the supplemental periods in defined to or approximately to a prescribed value Hsp at least whose foctor elements are a tolerable thickening rate DELTAmuT and an average viscosity change rate due to the evaporation of solvent DELTAmuH.

Title: Heat treatment apparatus
Inventor: SUDO KOJI
IPC: H01L21/223
Filed: 1985-06-13
Abstract: PURPOSE:To make temperature control easy, by applying the dual structured quartz tube between the semiconductor wafer and the heating means, installing a vacuum chamber in the tube, and performing exhaust and suction of this vacuum chamber. CONSTITUTION:The quartz tube 20 is heated by supplying a current through the heater 28, and the vacuum chamber 34 is kept in the high vacuum state in order that the heat may not conduct to the treatment room 24 for the quartz tube 20. The wafer 16 is set on the quartz boat 18, which is carried into the treatment chamber 24. When the gas of high thermal conductivity is gradually introduced into the vacuum chamber 34 so as to keep normal or higher pressure, the heat conducts from the side of the outer wall 30 of quartz tube 20 to the side of the inner wall 32 of quartz tube 20. This heat conduction is nearly uniform for the whole part of the treatment chamber 24, so that the thermal condition of the wafer 16 is constant independently of its position, which makes thermal control easy.

Title: Focus offset adjusting device
Inventor: TANAKA MASAO
IPC: G11B7/09
Filed: 1988-05-25
Abstract: PURPOSE:To highly accurately fit a focusing servo system to a proper focus offset variable within a short time by superposing a defocusing signal to a focus error signal. CONSTITUTION:A focus error signal to which a defocusing signal is superposed is synthesized with an offset signal (c) to drive a focusing actuator 11. An output signal from a main spot detector 12 is changed in accordance with a defocused variable, a signal (b) also generates a difference between a level corresponding to the period of its positive polarity and a level corresponding to the period of its negative polarity and a synchronism comparator 27 generates a defocused variable detecting signal (d) having polarity and size corresponding to the level difference. Thereby, a focus adjustment control circuit 29 controls an offset signal forming circuit 28. Thereby, the offset signal (c) is changed and a driving signal for the actuator 11 is also changed. Consequently, fitting operation to the focus offset variable can be highly accurately executed within a short time.

Title: Sheet discharge and loading device
Inventor: HAYAKAWA KIMIAKI
IPC: B65H29/18
Filed: 1986-06-03
Abstract: PURPOSE:To prevent sheet members to be defectively loaded on a tray and to permit them to be aligned at a position in a horizontal direction, gripping sheet members on loading means by drive means and confronting discharge means for discharging them and pressing them to drive and discharge means by a pressing member downstream of the confronting discharge means. CONSTITUTION:A sheet member S gripped by a belt 8, a first confronting roller 6 and a second confronting roller 10 travels to a point A on a tray 7 at a discharge angle theta1 of a belt 8. It is discharged along the inclined surface of the tray 7 after it reaches the point A. The sheet member S is pressed downwardly at its rear edge by a pressing member 12 at the time when the rear edge portion of it passes through a point where a second confronting roller 10 is brought into contact with the belt 8. As a result, the pressing member causes the sheet member S to be kicked out by the projections disposed around the belt 8 even if the rear edge portion of the sheet member S is curled. With the arrangement, since the projections on the drive and discharge means apply force to the sheet member S to securely kick out it, a defective loading of the sheet members on the tray is prevented and they are aligned at a position in a horizontal direction well.
