Patent JP-H01319988-A (JP)
Title: Printed wiring board
Inventor: UMEMURA YOSHIHARU
IPC: H05K1/02
Filed: 1988-06-22
Abstract: PURPOSE:To prevent the burying of a through-hole by respectively executing non-soldering treatment to one part of a conductor having a circule, etc., in the periphery of a through-hole plating hole and one part of the inwall of the through-hole plating hole continuing to one part of the conductor so as to penetrate a substrate. CONSTITUTION:A conductor 2 at through-hole periphery and one part of the inwall of a through-hole are plated with a metal on which solder does not adhere or non-soldering treatment 6 using a older resist is executed. Consequently, when a chip part previously arranged to a part inserting surface 4 is soldered, adhesion with the inwall 5 of the through-hole of solder 8 intruding into the through-hole is weakened. As a result, solder intruding into the through- hole is pulled and can be removed by the surface tension of solder in a solder tank at the time of drawing-up from the solder tank of a substrate 1. Accordingly, the through-hole is not filled-up with solder, and a part inserting hole and the through-hole can be operated in combination, thus increasing the packaging density of a part.

Abstract: PURPOSE:To make it possible to miniaturize and highly integrate cells and also effectively prevent the punch-through phenomenon by forming the third semiconductor layer of reverse conductive type with lower density of impurity than that of the first semiconductor layer deeply. CONSTITUTION:A semiconductor film 6 is formed on the first insulative film 5a formed on the main surface of a semiconductor substrate and is underetched to form a semiconductor film pattern 6, and an overhang-shaped mask is formed at the same time. Then, reverse conductive type ions with low density are deeply implanted into the substrate through the overhang-shaped mask so as to deeply form the reverse conductive type, third semiconductor layer 11, and further, reverse conductive type ions are shallowly implanted with the pattern 6 as a mask to shallowly form the first conductor layer 4. And one conduction type ions are implanted to form the one conduction type, second semiconductor layer 8. The second insulation film 5d is formed, and an opening 10a is selectively formed to partially expose the first semiconductor layer 4 and the second semiconductor layer 8 so that a metallic electrode film 9 is formed.

Abstract: PURPOSE:To prevent the deterioration in function of a filter by providing a discharge port to a bottom surface of the part close to the bottom surface and forming a filter medium of filter medium layer in the discharge side with ballast, broken stone or wood wool-like material. CONSTITUTION:One end of the inside of vessel of a main body 1 is partitioned at right angles for the flow direction by providing a perforated plate 4 perpendicularly to provide an inflow chamber A between the perforated plate 4 and the wall surface.

Title: Manufacture of high-polymer particle and manufacture of electrophotographic toner by using this method
Inventor: MOCHIZUKI HIROTAKA
IPC: C08L1/08
Filed: 1996-06-13
Abstract: PROBLEM TO BE SOLVED: To easily manufacture specific high-polymer particles having the high hydrophobic property of particle surfaces by suspension polymn. by using hydroxylpropyl cellulose specified in viscosity as a suspension stabilizer. SOLUTION: When manufacturing the high-polymer particles by suspension polymn. of a polymerizable monomer in an aq. medium, the hydroxylpropyl cellulose having the viscosity of <=10cps in a 1wt.% aq. soln. is used as the suspension stabilizer. The high-polymer particles or electrophotographic toners having the high degree of the surface hydrophobic property are formed if the hydroxylpropyl cellulose having the viscosity of <=10cps in the 1wt.% aq. soln. at 23 deg.C is used. The reason thereof lies in that the mol.wt. of such hydroxylpropyl cellulose is not particularly a high mol.wt. and, therefore, the easy outflow from the particle surfaces in the process of washing the particles after the suspension polymn. is conceivable. A remarkable effect is not admitted if the hydroxylpropyl cellulose of the viscosity higher than this numerical value is used.

Abstract: PURPOSE:To improve the homogeneity by equipping a mechanism for clamping molds with plural bellows, connected to a driving rod and installed corresponding to plural metallic molds and a pipe for connecting them and hermetically sealing the interiors of the plural bellows with a fluid. CONSTITUTION:The interiors of expandable and contractible bellows 7-1 and 7-2 in a number equal to that of metallic molds arranged in a plate 71 and a pipe 72 are evacuated to provide a vacuum state.

Title: Paper feed device
Inventor: TAKAHASHI YASUHIRO
IPC: B65H1/14
Filed: 1985-07-15
Abstract: PURPOSE:To surely prevent a suspending friction pad from a paper feed roller, by providing a pressing plate for pushing up a cassette and a supporting plate for moving a friction pad, on an operating shaft so that the cassette is lowered by pushing down a manipulation lever. CONSTITUTION:When a manipulating lever 19 is pushed down, an operating shaft 9 rotates clockwise by means of a release arm 15, and a pressing plate 14 fixed to the operating shaft 9 also rotates to lower the bottom plate 13 of a cassette 3. Then, the front end of the pressing plate 14 depresses a support plate 8 attached at its front end with a friction pad 5 which is therefore separat ed from a paper feed roller 4 overcoming the force of a spring 12. When the operating shaft 9 has rotated to a predetermined position, a pin member 12 on the release arm 15 is caught by a stepped section 21 in a lock lever 20, and the release arm 15 and a pressing shaft 24 are locked. At this time the release arm 15 is retracted into a cassette bed 3a which may be shifted onto a copying machine body. And when the pad 5 is joined to the roller 4, the bent part 27b of the release hook 27 is in the state capable of rotating, and therefore the engagement between the release ratchet 29 and release hook 27 can be released smoothly.
