Title: Mask lighting optical system
Inventor: MIMURA YOSHIAKI
IPC: H01L21/027
Filed: 1987-05-29
Abstract: PURPOSE:To realize uniform lighting with high light convergence efficiency by switching a convergent collimator lens to different focal length so as to vary the angle of lighting luminous flux on a body to be irradiated. CONSTITUTION:A positive lens 6 is arranged right behind an optical integrator 5, a stop 7 is provided further behind it, and luminous flux reflected by a reflecting mirror 8 is converged on the body surface 10 through the collimator lens 9. The aperture diameter of the stop 7 is varied to vary the collimation half angle, but the collimation lens 4 is replaced with a collimation lens which has long focal length when the aperture diameter is increased, or short focal length when the aperture diameter is decreased. Consequently, the mask lighting with high light convergence efficiency is realized all the time.

Title: Manufacture of lithium electrode
Inventor: NAGAI TATSU
IPC: H01M4/06
Filed: 1983-07-19
Abstract: PURPOSE:To prevent the corrosion of a lithium electrode by exposing lithium in a specific atmosphere and forming a protective coat on the lithium surface. CONSTITUTION:When a lithium electrode is manufactured, lithium is exposed in an argon or helium atmosphere where nitrogen exceeds 1,000ppm, water (A) is 0.3-200ppm and oxygen is 0-5ppm, water (B) is 4-200ppm and oxygen exceeds 5ppm and is less than 500ppm, or water (C) is 0-200ppm and oxygen is 500- 22,000ppm and a protective coat is formed on the lithium surface. As a result, the corrosion of lithium is suppressed subsequently even if it is handled in an atmosphere that can easily be obtained comparatively, for example, in dry air or nitrogen.

Title: Decoder for highly efficient code
Inventor: KONDO TETSUJIRO
IPC: H04N19/00
Filed: 1988-05-28
Abstract: PURPOSE:To improve decoded picture quality by using a picture element data adjacent timewise corresponding spatially to the picture element in the case of the picture element data during decoding at present being a picture element data of a block with frame omission processing and interpolating the data by an arithmetic mean applying weighting inversely proportional to a time difference with a time corresponding to the decoded picture element data. CONSTITUTION:In the case of the picture element data decoded at present being a picture element data of a block subject to frame omission processing, the data is interpolated by means of arithmetic mean using the picture element data corresponding spatially to said picture element data and adjacent timewise. For example, the time difference between the time of an original picture element data (b) and a time of a mean value 1/2(a+b) precedingly timewise is 1/2 frame because the mean value is generated at an intermediate time of the picture element data (a), (b), the time difference between the time of the original picture element data (b) and the time of the mean value 1/2(c+d) succeedingly timewise is 1.5 frame and a decoded picture element corresponding to the original picture element data (b) is obtained by the arithmetic mean inversely proportional to the time difference. The interpolation is repeated to apply the interpolation without any level change and offset of the original picture element data. thus, the decoded picture quality is improved.

Inventor: SHIBATA YUKIO
IPC: B29C45/23
Filed: 1986-06-06
Abstract: PURPOSE:To permit the injection of material having an uniform temperature, by a method wherein when an injection chamber is filled with the injecting material, a temperature of injecting material is detected and the opening degree of a valve is choked upon starting injection, thereafter, the opening degree of the valve is fully opened when the temperature of the injecting material has risen to a set temperature. CONSTITUTION:A valve controller 15 drives a solenoid valve 13 to control a valve 9 so as to opened half when a valve opening signal is inputted from a sequence controller 16, and compares a detecting temperature of a temperature sensor 12 with a temperature set in a temperature setter 14, thereafter, drives the solenoid valve 13 again to open the valve 9 fully when the detecting temperature has risen to the set temperature. Upon finishing the filling of material, the valve 9 is controlled so as to be closed based on a closing signal from the sequence controller 16. Thus, the injection chamber 2 is filled with the predetermined amount of the injecting material by a screw 7, since the material having a temperature close to a predetermined temperature is fed into the injection chamber 2 from the beginning of the starting of the filling of the material, the temperature of filled material becomes uniform substantially.

Filed: 1987-05-28
Abstract: PURPOSE:To decrease fluctuations in thickness within the same lot by forming NiPdP or NiAgP by plating on the surface of a substrate, then forming a magnetic film essentially consisting of Co by electroless plating thereon. CONSTITUTION:After the NiPdP or NiAgP is formed by the plating on the surface of the substrate, the magnetic film essentially consisting of the Co is formed by the electroless plating thereon. The film of the NiPdP or NiAgP is satisfactory if said film is formed on the substrate and needs not to be formed thick. The substrate for the disk has the higher activity and the induction time is shortened if the layer of the NiPdP or NiAgP exists on the subsurface. The fluctuations in the thickness of the magnetic film on the substrate are thereby decreased and the quality is stabilized.

Abstract: PURPOSE:To only execute a first rework so as to prevent the occurrence of picture omission on a form, by stopping an image forming operation only at a first judgement by which the optimum size of paper is not available. CONSTITUTION:When a copy start key is depressed, a document is fetched from a last page from an original tray 301 by a document feeder 300 and, when the document is set (fed) to a document glass, a document size signal is received and whether the optimum size of form is available or not is checked from the document size and magnification. If the judgement that no optimum size of paper is available is made at a first time after automatic paper selection is made, the copying operation is once stopped and a cassette exchanging request is made. When the judgement is made at or after a second time, the copying operation is continued without stopping by selecting copying paper of a size which is very close to the optimum size.
