Abstract: PURPOSE:To form a plated film having a uniform thickness on a wiring circuit board by conducting an electroplating so that a screening film having a mirror image of a reverse pattern of the circuit pattern is formed on the base surface and an electrode surface facing thereto so as to become the mirror image respectively. CONSTITUTION:A surface of a wiring circuit board alumina base plate 1-2 is roughened with a phosphoric acid solution, and after a Pd cell nucleus is fitted, is subjected to an electroless plating to form a thin copper layer. The screening film 1-3 having the reverse pattern of the circuit pattern 1-4 is formed on the surface of the base plate 1-2 and the plating electrode 1-1 facing thereto so that they become their mirror image. At that time, the end surface of the base plate 1-2 and the opposite side end surface of the electrode 1-1 are coated with a 'Mekki Resist(R)'. Subsequently, the base 1-2 and the electrode 1-1 are electroplated in a copper sulfate electroplating bath while facing their screening film formed surfaces 1-3 each other, after the copper plated layer having a uniform thickness is formed, lastly the screening film 1-3 on the base plate 1-2 is withdrawn, then the wiring circuit board is completed by withdrawing the thin copper layer under the screening film.

Title: Control device of picture density in copying machine
Inventor: ITOU MASAZUMI
IPC: G03G15/00
Filed: 1983-07-15
Abstract: PURPOSE:To prevent a pattern image from being expanded up to the unnecessary size at the expanding copying and also to prevent the consumed quantity of toner to be used for the development of the pattern from excessive increase by fixing the area of the pattern image to be developed independently of the copying magnification. CONSTITUTION:When the titled control device functions as an intra-image eraser, all LEDs are turned on and irradiate light to the whole width of a photosensitive drum, and in case of the automatic control of picture density, only a pattern formation part 4 is turned off at proper timing. In case of the function as an image end eraser, the control device controls only a proper part of erasing parts 4a, 4b so as to turn on. The LEDs are controlled by a CPU through a decoder. If continuous copying is discriminated by a step, the step discriminates whether the odd number-th sheet is being copied or not and picture density processing is executed only to the odd number-th sheet. Thus, necessary consumption of toner can be suppressed.

Title: Production of single crystal
Inventor: YASHIRO SATAO
IPC: C30B15/00
Filed: 1978-10-25
Abstract: PURPOSE: To enhance the reproducibility of single crystal producing conditions by solidifying a residual melt in a crucible from the crucible bottom to prevent deformation of the crucible by shifting the relative position between the crucible and a work coil.  
     CONSTITUTION: A sintered body of LiTaO 3  or the like is put into crucible 1 and heat melted with a heater such as work coil 5. After pulling a single crystal with a seed crystal, residual solidified crystal 2 in crucible 1 is supplied with sintered LiTaO 3  and heat melted to form a single crystal again. Coil 5 is then heightened relatively to crucible 1 to raise the temp. of the upper part of crucible 1, thereby solidifying the residual melt in crucible 1 from the crucible bottom. By this method deformation of crucible 1 is reduced to elongate the service life. Accordingly, changes in crystal growing conditions are minimized, and crystals are produced with high reproducibility.

Filed: 1979-10-09
Abstract: PURPOSE: To surely fix a workpiece on a guide plate, by providing the guide plate with a vacuum chamber for fixing the workpiece and with a valve mechanism for maintaining vacuum.  
     CONSTITUTION: While a workpiece 1 is lightly thrusted on elastic rubber 10, a vacuum supply pipe 14 is elevated and coupled to a pallet 2. At the same time, a valve stem 9 is rammed up by a push-up rod 15 attached to the pipe 14, thereby separating a packing 8 from a pipe 11. Pulling is then effected by vacuum through a vacuum hole 6 to put the vacuum chamber 7 of the pallet 2 under vacuum through the gap between the pipe 11 and the valve stem 9. The pipe 14 is moved down. The valve stem 9 is lowered by the force of a spring 12 to push the packing 8 into the pipe 11 to keep the vacuum chamber 7 under vacuum. As a result, the workpiece 1 is sucked and fixed on the elastic rubber 10 bonded on the pallet 2 by the vacuum suction force of the vacuum chamber 7.

Title: Method for preserving dried natural flower
Inventor: IMURO AKIO
IPC: A01N3/02
Filed: 1985-06-18
Abstract: PURPOSE:To preserve the original shape and color for a long period, by replacing and dehydrating a natural flower with an organic solvent, predrying the natural flower until the natural flower is in a bent state, putting the natural flower in a closed container and preserving the natural flower so as to be a frozen state. CONSTITUTION:A natural flower is dipped, replaced and dehydrated with an organic solvent, e.g. ethanol or methanol, and predried until the natural flower in the hard and readily broken state becomes the bent state, and then put into a closed container and preserved at <=-4 deg.C, preferably -4--15 deg.C to retain the original shape and color for a period as long as >=1 year. The predrying is carried out at 40-55 deg.C within 15min-2hr range depending on the kind and state of the flower and kind of the organic solvent, etc. A soft flower tends to cause wrinkles in predrying and a method for mixing a small amount of wax in the solvent for dehydration is adopted to prevent the wrinkle formation, etc. EFFECT:Since the flower can be preserved for a long period, the subsequent embedding in a transparent resin, etc., is readily carried out.
