Title: Moisture-permeable, water-barrier packaging bag
Inventor: MIYAKE TERUYOSHI
IPC: B65D30/02
Filed: 1989-06-02
Abstract: PURPOSE:To make a bag gas- and moisture-permeable completely all the time, yet permitting its water-barrier feature to be secured by forming tiny through openings in the film consisting mainly of polyolefin resins and the thermoplastic resins slightly miscible therewith. CONSTITUTION:Two sheets of gas-permeable film 2 and 3 are obtained by a method wherein the resin materials consisting mainly of polyolefin resins and the thermoplastic resins slightly miscible therewith are melted and kneaded, the resulting mass is extrusion molded into film and this film is treated with heat over a predetermined temperature range at non-shear rate, followed by quenching and then drawing. The gas-permeable films 2 and 3 have a number of tiny openings formed therethrough, indicating a high degree of gas- and moisture-permeability. By reason of these tiny openings, however, the gas- permeable films 2 and 3 keep out liquid such as water with a high degree of water-barrier feature. Vapor escapes to the outside through the tiny openings of these films and will not stay in a moisture-permeable, water-barrier packaging bag. Conversely, if water is splashed on such bag from the outside, it is kept from entry into the bag.

Title: Insulation abnormality detection for cable line
Inventor: ICHIYANAGI NAOTAKA
IPC: H02H3/00
Filed: 1986-06-19
Abstract: PURPOSE:To always detect insulation abnormality without fetching a signal from a high voltage section, by comparing ground currents on both sides of an insulating connection part of a cable to judge abnormality in the insulation when either thereof increases relatively. CONSTITUTION:Ground currents flow to leads 9A and 9B linked to an insulating connection part 3C as measuring point from cables 1C and 3D on both sides thereof and then, to first and second coils 12A and 12B respectively. An insulation abnormality detector 10 is adjusted with a tap changer 13 beforehand so that a magnetic flux in a circular core 11 is zero when a cable line 4 is normal. A charge current Ic of the ground currents depends on the electrostatic capacitance of the cables while the effective current IR thereof depends on the insulation resistance thereof. If a change is caused in the dielectric constant insulation resistance of one cable 1C or 1D, current flows to a third coil 13C and an alarm 15 sounds as it exceeds a specified level normal.

Title: Semiconductor device
Inventor: ISHIKAWA KATSUMI
IPC: H01L29/74
Filed: 1995-06-08
Abstract: PURPOSE: To reduce switching loss and enhance switching power strength by setting the emitter ground forward current amplification factor of a second region so that it is higher than that of a third region and lower than that of a first region. CONSTITUTION: A semiconductor substrate contains a first region 11 adjacent to auxiliary electrodes 32, 33, a second region 211 adjacent to main electrodes 31, 34, and a third region 12 adjacent to the area between the auxiliary electrodes 32, 33 and the main electrodes 31, 34. The emitter ground forward current amplification factor of the second region 211 is set to a value larger than that of the third region 12 and smaller than that of the first region 11. This prevents current from flowing from the main electrodes 31, 34 opposed to the auxiliary electrodes 32, 34 to the main electrodes 31, 34 adjacent to the auxiliary electrodes 32, 33. Thus switching loss is reduced, and high switching power strength is obtained.

Title: Dc machine stator core
Inventor: MATSUI TAKAYUKI
IPC: H02K1/20
Filed: 1977-11-28
Abstract: PURPOSE: To obtain good commutation by setting up a non-magnetic section in either main pole core or auxiliary pole core even with pulsating power supply.  
     CONSTITUTION: A non-magnetic material 10 engages with the position corresponding to the air hole 2 of the armature 3 in a main pole core 7 and a non-magnetic material 11 engages with an auxiliary core 8 at the position not opposed to the non- magnetic material 10 of the main core 7. Accordingly, since the section where the magnteic material of the auxiliary core 8 and main core 7 is opposed is reduced and the magnetic path of spatial leakage magnetic flux becomes long, leakage magnetic flux is controlled and a full size commutation magnetic flux is obtained on the space side. The commutation magnetic flux due to the auxilary core 8 can rectify and  compensate the change in the reactance voltage generated in an armature winding  which is shortcircuited by the brush due to pulsation of the armature current.

Title: Continuous hot dipping device for steel strip
Inventor: KODAMA MINORU
IPC: C23C2/24
Filed: 1981-09-08
Abstract: PURPOSE:To prevent the transverse oscillation of a steel strip in a titled device by installing an induction type linear motor on the upper stream side than a steering rolls in the cooling zone of a continuous heat treatment furnace and acting the thrust in the direction opposite from an advancing direction upon the steel strip. CONSTITUTION:A steel strip 1 passed through a continuous heat treatment furnace 2 is dipped in a plating bath 4, and is regulated of the coating weight of plating by gas wiping nozzles 6. The strip passes through a zero spangle device 7 and a galvanealing furnace 8 and is coiled. During this time, the strip is acted with tensile forces by bridle rolls 91, 92, but the tensile forces are weakened by the elongation generated in the steel strip by the effect of the heat of the furnace 2; therefore the strip is apt to oscillate transversely during the passage through the nozzles 6, the device 7 and the furnace 8. Therefore, electricity is conducted to a linear motor 10 to act the thrust in the direction opposite from the advancing direction of the strip 1 upon the strip 1 during operation. The tension on the strip 1 during the passage through the furnace 2 is weakened by said action and the tension on the strip 1 after the passage through the bath 4 is increased, whereby the transverse oscillation of the strip is prevented.

Title: Pseudo-random number generator
Inventor: SHIMADA MICHIO
IPC: G06F7/58
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To generate pseudo-random numbers having high resistance to correlation attack in a comparatively simple circuit constitution by thinning the clocks to be inputted to a linear (nonlinear) feedback shift register which generates the pseudo random numbers. SOLUTION: Bit series held by a shift register 801 are supplied to an output terminal 813 and a nonlinear function circuit 803. An exclusive OR circuit 802 calculates the exclusive OR of the bit of a prescribed position among the bit series held by the register 801 and supplies this calculation result to the register 801. Then the circuit 803 calculates the nonlinear connection of the bit of a prescribed position among the bit series held by the register 801, and this calculation result is outputted as a pseudo random number via an output terminal 814. In such a constitution, it's possible to generate the pseudo random numbers suitable for the stream ciphering without increasing the number of stages and pieces of shift registers and by thinning the clock pulses even when a pseudo random number generator consists of a nonlinear feedback register.
