Title: Single sheet material feeding mechanism
Inventor: KOBAYASHI RYUICHI
IPC: B65H3/08
Filed: 1986-03-06
Abstract: PURPOSE:To prevent multifeeding of sheet materials by providing engaging means for pressing the end portion of a sheet material held by an adsorbing disc to bend the sheet material and checking the plural sheet materials. CONSTITUTION:An elongated hole 126 is formed at the central portion of the first arm 122, one end portion of which is supported on an apparatus body in such a manner as to freely oscillate through a supporting point pin, and a crank pin 120 of a disc 118 is fitted in the hole. The second arm 130 is engaged with the other end portion of the first arm 122. A holder member provided with adsorbing discs 142a-c is engaged with the other end portion of the second arm 130. When the disc 118 is turned by drive of a servo motor so that the crank pin 120 reaches the lowermost position, the upper end of a sheet S held by the adsorbing discs 142a-c is pressed to a roller 174 to bend the sheet. Thus, the other sheet S1 adhering to the sheet 2 is separated from the sheet and stored in a supply magazine so as to prevent multifeeding.

Title: Substrate splitting method using carbon dioxide laser beam and manufacture of nonmetallic material made substrate parts using its method
Inventor: IMOTO KATSUYUKI
IPC: B23K26/40
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To provide a substrate splitting method using a carbon dioxide laser beam capable of surely splitting a substrate along a splitting guide groove precisely by particleless and dry processes. SOLUTION: When the substrate is split by irradiating the surface of the substrate 1 with the carbon dioxide laser beam, the splitting guide groove 5 for a splitting line is previously formed by a chemical etching technique, and the substrate l is split by irradiating the groove with the laser beam. The width and depth of the groove 5 is controlled with high precision because of forming by the chemical etching technique, consequently a cutting allowance width S for splitting is narrowly restrained and also a side surface of the groove is controlled to a uniform surface. Therefore, splitting is faithfully executed with high dimensional precision along the splitting groove and a side surface of the substrate after splitting is also kept uniform.

Title: Printed wiring board
Inventor: KIMURA MANABU
IPC: H05K1/11
Filed: 1995-03-09
Abstract: PURPOSE: To prevent the formation of a solder bridge between leads at the time of mounting a quad flat package on a printed wiring board. CONSTITUTION: A printed wiring board has a plurality of pads 32a, 32b,..., 32i formed in corresponding to the leads of a quad flat package, a dummy pad 34 formed adjacently to the pad 32i on the most downstream side of the pads with a gap d1 in between in the flow direction F of solder, and connecting section 37 to connect the pads 32 and 34 to each other with such a width that can inhibit the reverse flow of the solder. Therefore, an excessive amount of solder can be sufficiently brought to the dummy pad 34. The solder brought to the dummy pad 34 tends to flow reversely when the solder at the pad 32 is exhausted, the reverse flow of the solder can be blocked, because the width of the connecting section 37 connecting the pad 34 to the pad 32 is narrow.

Filed: 1985-03-13
Abstract: PURPOSE:To obtain a ferrite resin magnet which has less irregularity in magnetic property and high performance by forming the magnet of hard ferrite powder having specific composition, iron powder and/or iron alloy powder and polymer compound. CONSTITUTION:This magnet is formed of 50-96wt% of hard ferrite powder having a composition represented by the general formula of Mo.nFe2O (where M represents one of Ba, Sr and Pb, n=5.0-6.2), 0.002-1.5wt% of iron and/or iron alloy powder, and the residue of polymer compound. The ferrite powder having 0.5-5mum of mean particle can be used. If the mixture-in of the ferrite powder is too small beyond requirement, the magnetic property decreases, and if excess more, the molding becomes difficult. If the adding amount of the iron powder and/or iron alloy powder is less than 0.02wt% or less, the effect is eliminated, and if exceeds 1.5wt%, the fluidity is obstructed. The polymer compound may contain polyamide (nylon 6, nylon 6.6, nylon 6.10, nylon 11).

Filed: 1990-02-28
Abstract: PURPOSE:To improve the extent of responsiveness for valve opening or closing operation as well as to make injection fuel into high atomization by installing a spring, energizing a valve in a housing in the closing direction, and a driving means energizing it in the opening direction the other way, and forming this driving means from a horn, whose outer circumferential part is installed tight in the housing and one end is engaged with the valve and a piezoelectric element engaging with the other end of this horn. CONSTITUTION:Electric energy is fed to both piezoelectric element 24, 25 at time of other than fuel injection, and since energizing force of a spring 19 is higher than fuel pressure, fuel in a fuel chamber 12 is no longer injected. At time of fuel injection, ac voltage is impressed on these elements 24, 25 which generate an ultrasonic vibration, and this vibration is enlarged by action of a projection part 22a at a time when it is transmitted to a horn 21, then it is transmitted to a valve 18. Therefore a nozzle 14 is opened or closed by some frequency, thus fuel is injected. Simultaneously the fuel is atomized by vibrations of the valve.

IPC: B29C45/64
Filed: 1985-03-15
Abstract: PURPOSE:To shorten the molding cycle of a magnet by connecting bypass means to an electromagnetic coil in parallel at the time when a current in the electromagnetic coil is cut off. CONSTITUTION:If thyristors 12, 15 are operated, an exciting current shown by a full line arrow flows in electromagnetic coils 6,7. The exciting current rapidly attenuates while flowing through a thyristor 24 by making the thyristors 12, 15 OFF and the thyristors 24, 25 in a bypass circuit 23 ON at the time when melted magnetic plastic is injected in a cavity at the state of the stable exciting current and the coils 6, 7 are given a current for a time required for the magnetic orientation of magnetic particles. If thyristors 13, 14 are made ON, a demagnetization current shown by a broken line arrow flows. The demagnetization current rapidly attenuates passing the thyristor 25 by making the thyristors 13, 14 OFF and the thyristors 24, 25 ON at the time when the demagnetization current becomes stable. This can shorten a molding cycle.
