A static electricity measuring system including a probe, a measuring device, and a calibration device. The probe includes a sensor which detects an electric field and outputs signals representing the detected electric field. The measuring device measures static electricity on the basis of the signals output from the sensor. The calibration device generates a reference electric field. The measuring device is adjusted when the sensor detects the reference electric field produced by the calibration device.

Static electricity measuring system

The present invention provides a lenticular sheet in which cylindrical lens parts including a radiation curable resin are formed on one side of a transparent support, and at least a light-diffusing layer and light-blocking stripes are formed on the flat surface located on the opposite side of said sheet. Cylindrical lens parts with a fine pitch of 0.3 mm or less can be obtained; furthermore, finely pitched light-blocking stripes can be accurately formed in the desired positions. A projection screen constructed by combining the aforementioned lenticular sheet with a Fresnel lens sheet is ideally suited for viewing a liquid crystal projection TV with a high image definition.

Lenticular sheet, rear-projection screen or TV using the same, and

In the production of a tunneling probe tip having a sharp point by utilizing electropolishing, the present invention has enabled the production of a platinum tunneling probe tip always produceable in an identical conical form having high point sharpness without scattering in the shape caused by the anisotropy of crystal face with respect to the rate of polishing during polishing of a platinum material through adoption of a two-stage polishing process, which comprises subjecting a platinum tunneling probe tip material to a primary polishing for primary shaping of the tunneling probe tip material into a tunneling probe tip form, and then subjecting the shaped material to a secondary polishing for sharpening of the point with a mixed acid comprising sulfuric acid, nitric acid, and phosphoric acid.

Method of manufacturing a platinum tip

The invention relates to a method of making permanent magnets, especially rare-earth ion permanent magnets composed of compacted Fe-B-R type alloy particles. Accordingly, the method provides compacting the magnetic particles into a desired shape having voids between some of the compacted particles. The voids between the particles are filled with a sealing agent and the compact is further coated with either an organic coating or metallic coating.

A color original is picked up by a pickup head and B, G, and R image signals are obtained and supplied to a color process circuit including masking correction, under-color removal, and gradation correction circuits. Y, M, C, and K image signals output from the color process circuit are supplied to an exposure head to form a color separation plate. A print simulation unit having first and second frame memories is connected in parallel with the color process circuit. The B, G, and R signals are also written into the first frame memory. The signal read out from the first frame memory is supplied to the color process circuit and is color-corrected. The output from the color process circuit is written into the second frame memory and output to a color monitor. The second frame memory stores two frames, and can display both frames on the color monitor for comparison. The second frame memory has a data latch for latching a predetermined pixel signal, and a circuit for synthesizing the latched data in place of a predetermined pixel signal of the image signals. The second frame memory further has a comparator for detecting a pixel of the image signals having a level higher than a highlight set level, and a circuit for flashing the pixel having a level higher than the highlight set level.

An improved method of making a half-tone gravure printing plate in which a planographic or relief half-tone positive and a gravure screen are printed on a photosensitive resist forming material. In the method, the lowering of the quality of printed matter resulting from formation of moire pattern can be prevented and an error caused by the reproduction step between a new half-tone positive and an original half-tone positive can be corrected. The method comprises the steps of contacting and inverting the planographic or relief half-tone positive on a soft continuous gradation film to prepare a half-tone negative, screening in a photosensitive film with screen dots of the half-tone negative eliminated by use of a contact screen to prepare a new half-tone positive; printing the new half-tone positive on a photosensitive resist forming material to form an element of sizes of dots; and forming a space between the new half-tone positive and the photosensitive resist forming material, and printing said half-tone positive, blurring the screen dots, on the photosensitive resist forming material, thereby correcting an error of gradation of a middle tone portion.
