Title: Curl preventing member
Inventor: SHIGENOBU MICHIROU
IPC: G03G15/20
Filed: 1982-08-20
Abstract: PURPOSE:To reform curl resulting from heating or pressure application into the original state, by providing a guide member which has curvature in the opposite direction to the curl of an image supporting material right behind a heat or pressure source in the conveyance direction of the image supporting material. CONSTITUTION:Separating pawls 25-1-25-4 are supported pivotally at breadthwise intervals at the entrance of a curl preventing guide 27 for the image supporting material while energized to rotate, and their tips contact a fixing roll 1a. In a figure, 27d is the reference direction side of the image supporting material and one side of the image supporting material passes through this side regardless of whether the image supporting material is large or small. When the image supporting material is supported by the separating pawls 25-1-25-3 while its with deviates from the separating pawl 25-4, the image supporting material is not only not guided from the separating pawl 25-3 to right before the separating pawl 25-4, but also apt to curl toward the guide 27 by the heating, etc., of the fixing roll 1a. For this purpose, a notch part 27c is provided to the guide 27 so that even if an end of the image supporting material strikes the guide, the material advances smoothly. A image supporting material which is a little bit narrower than the interval between the separating pawls 25-1 and 25-3 is the same.

Filed: 1990-05-31
Abstract: PURPOSE:To efficiently make exact measurement by heating and dissolving polyethylene (PE) with carbon tetrachloride, analyzing the same with gel permeation chromatography(GPT) using the carbon tetrachloride as an eluent and detecting the same with a differential refractometer. CONSTITUTION:The eluent is previously passed from a moving phase storage tank 1 to form a stationary state. The injected sample is sent to a column 4 in a column oven 5 by the eluent and the mol. wt. distribution is detected by a detector 6. This data is processed by a data processor 7 which calculates the mol. wt. distribution. The exact measurement is efficiently made by making analysis with the gel permeation chromatography(GPT) using the carbon tetrachloride both as the PE eluent and the moving phase of the GPC and using the differential refractometer as a detecting means.

Filed: 1985-07-03
Abstract: PURPOSE:To make it possible to identify the position of IC chip and shape of it with accurate measurement by a method wherein an IC chip is converted into color image electric signals with color image-pick up means, and a TV image is used which is only made up with extracted color image electric signals of chomatic coating films specific to the surface of the IC chip.

Only the section of the chromatic coating film 2 from the TV image 5a displayed on the monitor TV 4 is shown in white image. The position and shape of the chromatic film 2 is very accurately formed for the circuit pattern since the coating film pattern is also photoengraved at the same time when the circuit pattern on the IC chip 1 is formed. Thus, the position of the IC chip 1, namely the accurate position and shape for the circuit pattern can be identified from the image 5a displayed on the monochrome monitor TV 5.

Title: Double cylinder tester
Inventor: ADACHI JUNJI
IPC: G01M13/02
Filed: 1986-06-23
Abstract: PURPOSE:To test a rolling transmission characteristic when a ring to be driven and a drive roller are inscribed with each other, by providing a pressurizing part to which the pressure contact force of the drive roller and the ring to be driven is applied steplessly. CONSTITUTION:The pressurizing device fixed to a testing stand 15 has a piston 13 mounted therein and the pressurizing pin 12 driven by said piston 13 pushes the pressure receiving part 7 mounted to a shaft 3 through a bearing 11 and generates contact pressure between a roller 4 and a ring 5 at a part A. The pressure receiving part 7 is fixed and connected to a support stand 17 in an axial direction in a state movable in an up-and-down direction by the pin 14. As a result, the force applied to the contact surface of the ring 5 and the roller 4 is shown by the relation of Pa=[b/(b+a)]P (where P is the force applied to the pressure receiving part 7 and Pa is the supporting force at the point A). Since the pressurizing pin 12 is driven by oil pressure, P is changed steplessly and, therefore, Pa can be also changed steplessly.
