Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To obtain an antenna radiation pattern of diminished disturbance by deviating the matching between the input impedance of an antenna element and the characteristic impedance of a power feeding system so as to reduce mutual connection between antenna elements. SOLUTION: The mutual connection between the antenna elements 3a and 3b is reduced by deviating the matching between the input impedances Z3a and Z3b of the individual antenna elements 3a and 3b arranged adjacently and the characteristics Z1a and Z1b of the power feeding circuits 1a and 1b. For example, the antenna elements 3a and 3b is constituted of a dipole antenna and the lengths of the antenna elements are set to be l1 and l2 , power is supplied from the power feeding circuits 1a and 1b at asymmetrical positions where l1 ≠l2 . By feeding power asymmetrically like this, the mutual connection between the antenna elements 3a and 3b is reduced to be small to improve the disturbance of a radiation pattern as individual arrayed antenna elements 3a and 3b and the array antennas.

Title: Rewinding method for extra fine wire
Inventor: NAITO MASAO
IPC: B65H54/32
Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To cope with an increase in length by increasing the number of windings preventing a bite in each layer during rewinding of an extra fine wire as the extra fine wire is prone to be bit when it is reversed in a turning part during winding on a spool because respective wires are arranged parallelly and nothing prevents a newly arranged wire from dropping in a gap between the previously wound wires. SOLUTION: In this method for rewinding an extra fine wire on a winding spool in form of cross winding from a feeding spool on which the extra fine wire is wound, a traverse width is varied in every traverse. When a mean value of the traverse width is reduced as the wire is wound on the upper layer, a traverse fluctuation width WT and a reduction in the mean value of the traverse width WL satisfy the following: 2WT/WL<0.5.

Filed: 1991-07-24
Abstract: PURPOSE:To reduce a current consumption at the time of performing an access to one column by making the number of data lines connected with a column line at the time of a mode in which the access to the plural line column lines is simultaneously attained by controlling a connecting means, different from that at the time of the mode in which the access to one column line is attained. CONSTITUTION:At the time of a block write mode, a block write signal BLW is turned to 1, and control signals Y0 and Y1 for connection outputted from a partial column decoder 10 are turned to 1, so that the decoder 10 and the connecting means can be formed. For example, transfer, gate transistors T0-T4 are turned ON through a column decoder CDO or the like by plural column selecting lines CSLO and CSL1, so that four column lines can be connected with four data lines DQ0-DQ3. In the same way, in one bit mode in which one column line is selected, only one of the selecting lines CSL0 and CSL1 is selected, so that two data lines can be connected with one column line, and the current consumption at the time of one bit read and write can be decreased.

Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To obtain a high contrast liquid crystal display element with a low driving voltage without increasing viscosity of the liquid crystal layer by adding hydrogen bonding donor molecules to the liquid crystal layer. SOLUTION: A first substrate 1 on which a first electrode 3 is formed and a second substrate 2 on which a second electrode 4 is formed are placed opposite to each other. Alignment layers 5, 6 which are subjected to homogeneous alignment treatment are provided on the respective substrates. Injection of a mixture of a nematic liquid crystal 7, a black dichroic pigment 8 and benzoic acid 9 into the cell formed with the two substrates 1, 2 results in homogeneous alignment in the cell. On making light incident on the cell via a polarizing plate 10, in the case the orientation direction of the dichroic pigment 8 coincides with the polarization direction, a dark state is realized because the light is absorbed by the pigment 8 and is transmitted or reflected.  When the polarization direction and the orientation direction form 90 deg. angle, no more absorption by the pigment 8 occurs and a bright state is realized. The addition of benzoic acid is preferably <=20 mol%.

The inhibition information of the means 1 is freely altered into the permission information through the altering means 3 controlled by a CPU, etc., as the sound generation of the channel musical sound is elapsed. This constitution performs proper truncation inhibition control to reduce the feeling of incongruity as to the performance representation.

Abstract: PURPOSE:To prevent generation of bite of tungsten at an opening part by growing a silicon epitaxial layer only at the opening part of an insulating film using a selective epitaxial growth technology for the silicon of vapor phase reaction. CONSTITUTION:Prior to filling a contact hole with tungsten 7, making use of a selective epitaxial growth technology for silicon of vapor growth, an epitaxial layer 6 of silicon is grown only at the opening part of an interlayer insulating film 4. At this time, the thickness of the silicon layer to be grown at the opening part is confined to below the thickness of the interlayer insulating film 4. And after filling the contact hole with the tungsten 7, wiring is done by means of Al-Si-Cn alloy deposited films 8. Hereby, the growth of the tungsten 7 advances only in the longitudial direction of a wafer 5, and the downward reaction of the insulating film 4 is suppressed, therefore the bite does not occur.

Title: Access system for i/o device
Inventor: TANUMA JIRO
IPC: G11B19/20
Filed: 1986-08-08
Abstract: PURPOSE:To use the circuit of an interface control part in common and to mount all circuits on an IC chip by providing an address register in the control part of an I/O device, and clearing it to the same value at the time of initial resetting and then setting addresses of respective I/O devices with input serial data. CONSTITUTION:When serial data is received, the value of an address part 41 is compared with the contents of the address register 33 of a motor device and when the value is recognized to be a command to this motor device, the instruction area 43 of a data part 42 is decoded to execute the command, thereby entering the driving process of a motor. For example, when serial data is issued whose address part value is 2, the motor device which has '2' stored in the address register 33 recognizes that and executes the command. When the value of the address part 41 does not coincide with the contents of the address register 33 of the device, on the other hand, it is judged that this serial data is for any other motor device, and the data is left as it is.
