Title: Photometric device for camera
Inventor: TSUNEFUJI KATSUHIKO
IPC: G03B7/099
Filed: 1981-06-15
Abstract: PURPOSE:To eliminate photometric errors owing to the differences in light reflectances between the curtain plane of a shutter and the plane of a photographing film by setting plural pieces of photodetectors selectively in a photodetecting state in conformity with the traveling positions of the front curtain of the shutter. CONSTITUTION:In the initial period when the front curtain of a shutter starts traveling, photodetectors P1 and P2 receive mainly the reflected light from the front curtain, and the photocurrents generated in these photodetectors P1, P2 are integrated through transistors Q1, Q2 in an integrating capacitor C1, so that the charging voltage increases gradually. When the front curtain of the shutter is going to end traveling, a photodetecting selection switch S3 is turned on and the other photodetector P2 is set in a non-photodetecting state, thus the integration of the photocurrents in the capacitor C1 is continued in accordance with only the photocurrent generated in the photodetector P1. When the charging voltage of the capacitor C1 attains a prerescribed voltage, and rear curtain travels, and the exposure of the subject image on the plane of a photographing film is completed.

IPC: B21D47/00
Filed: 1990-04-10
Abstract: PURPOSE:To obtain a metallic sandwich panel having smooth surfaces by joining face sheet materials and a core material small in deformation resistance meanderingly and forming the face materials and core material heated at a prescribed temperature as the spaces between them are charged with fluid pressure. CONSTITUTION:The core material 1 small in deformation resistance is arranged between the face sheets 2a, 2b to join the joined parts 3 meanderingly. When the spaces between the above face sheet materials 2a, 2b heated at the prescribed temperature and the core material 1 are charged with fluid pressure P, the core material shows superplastic flow at a prescribed forming temperature and since the deformation resistance is drastically small to the face sheet material, the core material only is deformed to perform prescribed forming.

Abstract: PURPOSE:To continuously and automatically perform washing works on photosensitive resin plates so as to improve the production efficiency of the plates, by providing a rotary brush for washing contacting with the plates while it is rotated and a cleaning means for cleaning the washed plates. CONSTITUTION:When a plate 1 with a steel-made base board is supplied from a plate inlet 19, the plate 1 is fetched by a nip roll 10 and attracted and fixed onto a carrying belt 6 by the magnetic action of the belt 6. While the plate 1 is carried by the belt 6, washing of the plate 1 is carried out in a rotary brush section. The washing speed is changed depending upon the concentration of the photosensitive resin dissolved into the washing liquid, but the speed is corrected by adjusting the speed of the belt 6 so that the optimum relief can always be obtained. It is desirable to detect the concentration of the resin in the liquid and automatically adjust the speed of the carrying belt 6 in accordance with the concentration, but the installation of equipment is expensive. Therefore, it is convenient to carry out the speed adjustment in such a way that the concentration fluctuation id divided into steps and the speed of the belt 6 is manually adjusted at every concentration step.

Title: Molten recrystallization method for thin-film semiconductor crystal
Inventor: KAMATA ATSUSHI
IPC: H01L21/20
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To expand a crystal particle diameter with good reproducibility and to suppress forming of a crystal particle boundary to the direction of accumulation by radiation heating of a piled product surface with a light beam and by heating it to higher than a specified temperature on a piled product near surface through heating. SOLUTION: The rear surface temperature of a piled product 15 is heated to higher than about 1,000 deg.C by heating a substrate 16 with a heater 17. Also a prescribed oscillating line of a YAG laser 12 is applied to the surface of a piled product 15 by forming the line beam by an oscillation device 11. When the line shape beam is applied in the state without a temperature distribution difference between the substrate 16 and the surface, light absorption occurs on the surface layer of the piled layer 15, the piled layer is molten from the surface and the melting progresses up to the substrate 16 side. When the ling shape beam is transferred, the surface is rapidly cooled through radiation and solid crystallization progresses from the surface.  Thus crystal particles having a layer particle diameter in a so-called 'column state' where no crystal particle boundary progresses in the piling direction can be formed.

IPC: G01N1/14
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To improve maintainability, and size and cost reduction by forming a sample sucking mechanism for a flow cell using an electromagnetic pump. SOLUTION: A spectrophotometer is provided with a flow cell 3, an electromagnetic pump 8, a waste liquid tube 9, a suction nozzle for sample 6 and so on.

IPC: G11C19/08
Filed: 1980-07-09
Abstract: PURPOSE:To obtain a stable magnetic bubble memory device to increasing the margin of gate operation by applying a holding magnetic field along a major line. CONSTITUTION:According to an in-surface revolving magnetic field HD, a magnetic bubble transferred through a major line consisting of permalloy elements 14-, 15-, and 16- reaches the point (b) of permalloy 19 forming a gate from the point (a) of the element 15. Further, the magnetic bubble is tranferred to a minor line composed of permalloy elements 20, 17 and 18 to complete transfer in operation. Applying a holding magnetic field Hb along this major line increases a repulsive  magnetic field at the point (a) in a 270 deg. direction and the gradient of the magnetic field between the points (a) and (b) increases, stabilizing the operation of the magnetic bubble. Therefore, the margin of a current for magnetic bubble transfer applied to a conductive pattern 21 increases and the transfer-out operation is the same, so that the stable magnetic bubble memory device is obtained.

IPC: B41J2/175
Filed: 1990-04-11
Abstract: PURPOSE:To maintain an ink jet recording head constantly in a state where it can discharge ink accurately by making an ink flow variable in accordance with time spent from a previous head cleaning process when the head is cleaned. CONSTITUTION:If a power supply for an ink jet recording device is turned ON, a clock 35 connected to a backup cell 37 is checked to determine whether it operates normally. After that, CPU 31 reads a current time and a previous head cleaning time in a memory register 36 from the clock 35, and determines the time spent from the previous head cleaning point of time. Then CPU extracts suction pressure data and suction time data corresponding to the determined spent time, referring to a cleaning amount control table in ROM 32, and sends these data to a cleaning control circuit 40. In the cleaning control circuit 40, any appropriate drive voltage for the suction pressure data is applied to a suction pump motor 80 by time corresponding to the suction time data. Thus ink is forcibly discharged to an ink jet recording head 2.
