Patent JP-S6061224-A (JP)
Title: Injection molding device
Inventor: JIYOBUSUTO URURITSUHI GERAATO
IPC: B29C45/30
Filed: 1984-07-31
Abstract: This invention relates to an injection molding system of the type wherein a heated probe is centrally located in the hot runner passage. The probe has a pair of circumferentially spaced melt channels, each with an upstream portion which branch out from a common central inlet to a downstream portion along the outer surface of the probe. The probe is seated in a well in the cavity plate and a hollow cylindrical insulating sleeve is located between the downstream portion of the probe and the wall of the well. The outer surface of the probe and the inner surface of the insulating sleeve have longitudinally extending grooves which are aligned to form the downstream portions of the melt channels. The insulating sleeve is formed of a thermoplastic material with low thermal conductivity and a high melting temperature. In addition to insulating, the sleeve provides the advantage that it avoids the space between the probe and the well wall filling with melt which often results in problems on color changes and the degradation of the stagnant material which is trapped.

Title: Electrostatic recording sheet
Inventor: YAMAUCHI KEIJI
IPC: G03G5/02
Filed: 1987-06-29
Abstract: PURPOSE:To enable the recording of a sharp color image having a high contrast by providing >=82% whiteness to the surface of a dielectric layer. CONSTITUTION:The whiteness on the surface of the dielectric layer measured in accordance with JIS P8123 is specified to be >=82%. Selection of a base is important and the use of a material having the high whiteness is essential in order to obtain an electrostatic recording sheet having such high whiteness. While the high whiteness of the conductive layer and dielectric layer is important, the film thickness thereof is intrinsically small and, therefore, the selection of the base is most important. The wood free paper formed by a Fourdrinier paper machine using pulp or the pure white roll paper produced by a Yankee machine is consequently used as the base having the high whiteness. The electrostatic recording sheet which can record the sharp image having the high density and contrast is thereby obtd. when the sheet is used for recording of the color image with a color electrostatic plotter.

Abstract: PROBLEM TO BE SOLVED: To make correctly measurable the concentration of an abnormal prothrombin (PIVKA-II) without being effected by various interfering substances existing in a specimen by using a buffer liquid containing lactoprotein as the buffer. SOLUTION: A buffer is used for reaction between a specimen and a primary antibody solid phase and/or for reaction with a marker secondary antibody, and preferably the buffer used for the reaction between the specimen and the primary antibody solid phase contains lactoprotein. 0.1 wt.% or more, especially 0.1-10 wt.%, and preferably 1-5 wt.% of the lactoprotein should be added into the buffer in terms of attraction prevention effect of interfering substance. Measurement is carried out by performing reaction through addition of lactoprotein contained buffer to the primary antibody solid phase beads and the specimen, then performing reaction with the secondary antibody, and measuring a signal of the marker secondary antibody connected with the primary antibody solid phase beads.  By taking out the beads from a reaction vessel and then performing the measurement, an accurate measurement can be made. Even if an interfering substance is attracted to the reaction vessel, there is no influence on the measurement since only the primary antibody solid phase is measured.

Abstract: PURPOSE:To improve the picture quality by adopting a circuit in which a DC amplifier is used for a video amplifier and connecting an input terminal of the DC amplifier to ground only for a back porch period. CONSTITUTION:A DC amplifier 23 able to amplify uniformly a DC component and a high frequency component included in an input signal is used for a video amplifier.
