Title: Simple pcb measuring instrument
Inventor: AONO AKIRA
IPC: G01N30/04
Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To enable a simple PCB measuring instrument to make cleaning-up and graduation with a small amount of solvent without requiring any concentrating treatment within a shortened processing time. SOLUTION: At the time of measuring coplanar PCBs, the cleaning-up and graduation which are performed between rough extraction for extracting the coplanar PCBs into an organic solvent and the analysis by means of an analyzer are performed by high performance liquid chromatography instead of the conventional column chromatography. Since the high performance liquid chromatography is used, the time required for the cleaning-up and graduation is shortened and the required amount of the solvent is reduced. In addition, no concentrating process is required. Moreover, the cleaning-up and graduation can be carried out continuously by controlling the supply of a sample liquid to each treatment column during the course of high performance liquid chromatography.  Furthermore, even a plurality of samples can be treated continuously by performing the introduction of the chromatography by automatic injection and the batching-off of the graduated coplanar PCBs by automatic dispense.

Filed: 1988-10-13
Abstract: PURPOSE:To improve memory holding characteristics by forming a silicon nitride film by a vapor phase method utilizing plasma excitation reaction after the formation of a gate electrode, and thereafter performing fluorine ion implantation, heat treatment and the like. CONSTITUTION:A gate electrode layer 8 is formed on a first silicon nitride film comprising a silicon nitride film 6 and a silicon dioxide film 7 on a P-type silicon semiconductor substrate 1.

IPC: H01L21/3213
Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To eliminate a partial etching residue of a metal film and a barrier film while a semiconductor film is left alone, by allowing a sample temperature to be a specified value when etching with plasma a metal film of a multi-layer film which comprises a metal film, a barrier film, and a semiconductor film. SOLUTION: A sample 106 which comprises a multi-layer film comprising a metal film, a barrier film, and a semiconductor film is sucked to a sample stage 108 while a plasma 105 is generated with an inert gas to raise the temperature of the sample. After confirming with a temperature sensor 107 that a sample temperature is 100-200 deg.C or above, a plasma 105 is generated to etch the metal film and the barrier film up to the upper layer part of the semiconductor film. With etching using the plasma 105 at a high temperature, the etching speed of the metal film is raised while that of the semiconductor film is not raised. Thus, the semiconductor film is left alone with no partial etching residue for the metal film or barrier film.

Abstract: PURPOSE:To distribute an optical signal uniformly on a plane by emitting light from plural light sources to the inside of a lens array in which plural lenses provided with negative curvature are formed on a transparent material surface with refractive index higher than that of the air via the lenses, and receiving the light with plural photodetectors via the lenses. CONSTITUTION:The light connection device is comprised of a glass plate 1 on one plane of which a large number of small spherical holes(lenses) 4 are provided, the light source 2, the optical system 3 of the lens to make incident the light emitted from the light source 2 from the hole 4 of the glass plate, the photodetector 5 to receive the light emitted from the hole 4 of the glass plate, and a beam splitter 6 to separate the light. The light emitted from the light source 2 is converged by the optical system 3, and is made incident on the inside of the glass plate 1. Incident light at angle larger than the critical angle of the glass plate is total-reflected and is confined in the inside. Since the emission angle of the light from the inside is decreased than the critical angle at a part of the hole 4, the light is emitted to the outside of the glass plate, and is made incident on the photodetector 5. By forming a large number of holes in two-dimensional fashion, the light can be distributed and emitted from those parts.

Title: Ink sheet transfer device
Inventor: MURANAKA MASAICHI
IPC: B65H20/02
Filed: 1987-10-14
Abstract: PURPOSE:To prevent image quality degradation and recording paper skewing, by mounting torque limiters each to the rotation shaft of a transfer roller and the take-up shaft of an ink sheet and transfer an ink sheet with a proper tension applied. CONSTITUTION:A take-up shaft 2 has a torque limiter 15 and is driven directly by a motor 6 which also drives a transfer roller 5 via a belt 19, torque limiter 20 and belt 22. The rotation speed of the roller 5 is set 5-10% faster than the running speed of an ink sheet at a printing section 4. Thus, an excessive tension on the ink sheet 3 is removed by slippage caused by a second torque limiter 20. A torque limiter 15 on the take-up shaft with the same construction also prevents a running speed increase to be caused by an increased ink sheet outer diameter and an excessive tension.
