Title: Injection-molding resin for flame-resistant coverage
Inventor: ERUNSUTO UITSUPUFUERUDAA
IPC: C08G59/30
Filed: 1990-08-07
Abstract: The halogen-free casting resin which is suitable in particular for providing the electric and electronic components with a flame-retardant covering and which contains the acidic ester of a phosphorus compound having hydroxyl functional groups and of an organic anhydride is proposed. Stable mixtures can be prepared from the acidic ester and the curing component of the casting resin and can be used for curing any epoxy resins. The reactive acidic ester is chemically incorporated in the resin matrix and thus imparts improved long-term flameproofing properties to the casting resin moulding compounds without adversely affecting their other properties.

Filed: 1989-08-17
Abstract: PURPOSE:To enable precise measurement of the pulse width of a narrow input pulse without using a high clock frequency, by measuring the pulse width by a clock signal after the width is extended on a time base by utilizing a difference in a time constant of charge and discharge. CONSTITUTION:When a noise signal (in) is inputted to a comparator CP1, a voltage of a reference voltage V1 or above is outputted therefrom as a rectangu lar wave signal A and a switch SWa is turned ON, while SWb is turned OFF through an inverter 1. At this time, a current i1 corresponding to a resistance R1 is outputted for a time t1 (a time corresponding to a pulse width) from a supply voltage Vcc connected to a constant current source 2 and it is charged on a capacitor C1. When an input pulse turns to be below the voltage V1, the SWa is turned OFF while the SWb is turned ON, and the capacitor C1 is dis charged B (a time of discharge depends on a resistance R2) through a constant current source 3, the current being than a reference voltage V2, the CP2 outputs a rectangular wave C of a width t2 (the degree of amplification thereof is decid ed by a difference in a time constant of charge and discharge on and from the capacitor C1). This width t2 is counted 6 by a clock signal.

Abstract: PURPOSE:To highly integrate a semiconductor non-volatile membory and to improve the reproducibility of writing/erasing characteristics of the memory by associating a tunnel operation unit in a gate section, thereby maintaining the area constant without resorting to masking accuracy. CONSTITUTION:With a nitrided film 9, an oxidized film 8 and a resist film 10 as masks an n<+> type layer 7 is formed on a P type substrate, the film 10 is removed, and a gate insulating film 11 having approx. 700Angstrom  of thickness is formed.

According to this structure, electrostatic capacity between a drain for controlling the writing/erasing characteristic and the floating gate depends upon the area of the part of the film 12, but does not depend upon the masking accuracy and can be maintained constant. Accordingly, the reproducibility of high integration and electric characteristics can be improved.

Further, the air passes through air holes 6 and 7 of the sirring body 4 and the bubble, which is generated in a lower direction, in a washing tank 3 is also a little generated during the drive of the stirring body 4 and much generated during the stop of the drive.

Abstract: PURPOSE:To weave three-dimensional woven fabric in high efficiency using a rod- process by using a pushing mechanism to insert a weft-direction rod between a number of warp-direction rods and driving the mechanism in controlled state to prevent the interference of the inserted rods. CONSTITUTION:Three-dimensional woven fabric is produced by a rod-process comprising the successive insertion of a number of weft-direction rods from different directions between the rods of warp-direction rod group consisting of a number of parallelly arranged warp-direction rods. A plurality of pushing mechanisms to insert the weft- direction rods are placed in a state staggered in the weaving direction and the pushing operation is controlled by a controller. The controller drives the rod-insertion mechanisms in high efficiency while avoiding the mutual interference either by driving lower insertion rods to expose each tip end of the rods beyond the arranged region of the upper insertion rods before the end of the insertion of the upper insertion rods or synchronously driving the upper and the lower rods to coincide the insertion end periods or by stopping the insertion of each insertion rod when the tip end of the inserted rod is in a state protruded from the arranged region of the other insertion rods and finishing the insertion at a stroke after all insertion rods reach the above insertion positions.

Title: Method for controlling output of power source for welding
Inventor: OGASAWARA TAKAAKI
IPC: B23K9/073
Filed: 1983-11-10
Abstract: PURPOSE:To prevent arc breakage owing to the plunging of a welding wire by passing immediately high short-circuit current to accelerate melting and melt cutting of the welding wire and to generate the arc in short time when the welding wire short-circuits with a molten pool before said wire is not melted yet and does not form a droplet. CONSTITUTION:The waveform of the welding current as shown in the figure is used in the stationary short-circuit transfer in which the droplet is smoothly transferred to the tip of a welding wire 11. Low short-circuit current period TSS is omitted only when a wire 11 contacts and short-circuits with a molten pool 14 before a droplet 12 is not formed at the tip of the welding wire or while the droplet 12 is small owing to certain cause, i.e., when the short-circuit arises in a high arc current period TAP in the waveform of the welding current shown in the figure. High short-circuit current TSP is impressed right after the short- circuit to accelerate the formation and melt cutting of the droplet. The time to the generation of an arc is thus reduced to prevent the plunging of the wire 11 and to reset the unstable short-circuit transfer welding to the normal short-circuit transfer state.
