Title: Water drop flowability improver for water-repellent-treated glass
Inventor: KAWAHARA MIKI
IPC: C03C17/30
Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To obtain a water drop flowability improver effective in improving water drop flowability and durability by incorporating a water-repellent oily substance into the same. SOLUTION: This improver has durability inherent in a fluoroalkylsilane-base one and water drop flowability inherent in a silicone-base one. Examples of the water-repellent oily substance are silicones and modified silicones. Generally, when a water-repellent oily substance is applied to a glass surface pretreated with a silane coupling agent (e.g. an alkylsilane coupling agent), high water repellency and water drop flowability are achieved, unlike the case when the oily substance is directly applied to a glass surface. The upper limit of viscosity (20 deg.C) of the oily substance is 1,000 cSt or lower, and the lower limit, 1 cSt or higher. When the substance is used, the upper limit of concn. is 50 wt.% or lower, and the lower limit, 0.01 wt.% or higher.  A water-repellent oily substance which is pref. also in terms of durability of effect is a fluorine-modified silicone comprising a main polydimethylsilicone chain and fluoroalkyl groups bonded thereto.

Filed: 1986-12-08
Abstract: PURPOSE:To reduce time required for calculating the integer times of multiplicands and the number of registers for storing multiplicands by making it possible to subtracting the outputs of two selecting circuits in addition to the addition of the outputs of the two selecting circuits in the case of scanning multipliers by plural bits and accumulating the partial product of multiplicands. CONSTITUTION:In the case of scanning multipliers every 3 bits, accumulating the partial product of multiplicands and executing multiplication, an accumulation register 5 is divided into an upper digit and a lower digit, at first a multiplier B is set up in the lower digit and zero is set up on the upper digit. The least significant 3 bits in the register 5, i.e. the lease significant 3 bits of the multiplier B, are checked by a decoder 6, the values of the 0-7 times of a multiplicand A are added to the upper digit value of the register 5 in accordance with the checked value, the added results are stored again in the upper digit of the register 5, both the upper and lower digits are shifted by 3 bits in the lower digit direction. The decoder 6 checks the least significant 3 bits of the register 5 again and adds the checked value to the register 5. After ending the scanning of all multipliers B by means of the decoder 6 by repeating said operation, a product of AXB is obtained from the register 5 combining the upper and lower digits.

Title: Low loss dust core
Inventor: KONDO KOICHI
IPC: H01F1/147
Filed: 1997-10-08
Abstract: PROBLEM TO BE SOLVED: To enhance reliability by providing the constitution, which comprises the mixed powder of solft magnetic metal material and permanent magnetic material, has a structure of which an S-pole at one end of the cross section perpendicular to a magnetic path and an N-pole at the opposite pole of the S pole. SOLUTION: A compressed dust body comprising soft magnetic metal material and permanent magnet material 1 is magnetized in a vertical direction 3 with respect to its magnetic path direction 2. Thus, as S-pole is provided at one end of the cross section which is perpendicular to the magnetic path, and an N pole is provided at the opsite pole. The magnetic flux of the surface is set at 100-1,000 G. The reason for the surface magnetic flux being set at 100-1,000 G in the magnetizing direction is that, when the magnetic flux is smaller than 100 G, a magnetic wall is present and the loss is not decreased. Furthermore, when the value is larger than 1,000 G, the alignment of spin in the exciting direction is not easy, and the loss other than hysteresis is deteriorated.  The reason why the total loss of the dust core can be decreased in this way is the fact that the hysteresis loss and the vortex loss are both decreased by mixing the permanent magnet material powder and applying the magnetic field in the direction perpendicular to the magnetic path.
