Title: Ink recording device
Inventor: KOBASHI TADAO
IPC: G01D15/16
Filed: 1983-05-31
Abstract: PURPOSE:To prevent the deterioration of the quality of a recorded image due to the deficiency of liquid ink, by a construction wherein a vessel having a bottom part permeable for the liquid ink is provided on the upper electrode permeable for the liquid ink out of two electrodes, through the intermediary of a plurality of mutually-separate ink-conducting parts, in an ink recording device utilizing electroendosmosis. CONSTITUTION:Liquid ink 35 stored in an ink supply vessel 30 drips spontaneously through small orifices 32 as indicated by arrows 36 and is conducted along an ink-conducting part 33 as shown by an arrow 37, and thus liquid ink 5 is supplied to a second electrode 6. Moreover, the ink-conducting part 33 formed as a projection attached to the vessel 30 makes a gap 38 from the second electrode 6. Consequently the liquid ink 5 is given a large freedom of movement, and the ink can be supplied directly along the ink-conducting part 33 which is distributed two-dimentionally on the virtually all the surface of the second electrode 6. According to this constitution, a necessary quantity of ink can be supplied even when an ink recording head 1 operates at high speed, thus eliminating the non- uniformity in an image on a recording medium 8 due to the deficiency of ink which is caused by the non-uniformity in the supply of the liquid ink.

IPC: H05B3/00
Filed: 1991-04-03
Abstract: PURPOSE:To measure the PVT curve of a resin with respect to desired pressure within a short measuring time. CONSTITUTION:A resin R to be measured is put in a thermostatic tank 11 held to predetermined temp. T. A piston 20 is moved to press the resin R and fixed at a predetermined position.

When (n) pairs of data (P, V) are calculated by changing the position of the piston, Spencer-Gilmore state equations are determined by the measuring of least squares. This operation is repeated with respect to (m) kinds of temps. to obtain (m) kinds of state equations. On the basis of each of the state equations, the PVT curve showing the relation between the temp. T and the volume V wherein a desired pressure value is set to a parameter is obtained.
