Title: Computing method for interface voltage of resistance welding and its interface resistance, and monitoring method for welding quality
Inventor: RIYUUDOU MAKOTO
IPC: G01N27/04
Filed: 1996-01-23
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of monitoring the welding quality by computing a voltage or resistance occurring on the interface of an electrode and a welded material from voltage between the electrodes to sandwich the welded material or the resistance between the electrodes computed from the voltage between the electrodes and welding current. SOLUTION: In the case where the resistance of an electrode it self is denoted by electrode resistance Rec; resistance inside a welded material by plate resistance Rreal; resistance occuring on the interface of the electrode and the welded material by resistance between a plate and the electrode Rde; and resistance occurring on the mutual interfaces of the welded materials by resistance between the plate and the plate Rdc; a measured resistance Rmeas measured from the electrode or an electrode holder is expressed as follows; Rmeas=2Re1+2Rreal+2Rde+Rdc. The resistance Rei can be measured by supplying the current in a state where the welded material is not sandwiched. The resistance Rde can not finally ignore influence on account of the wear of the surface of the electrode with the increase of the number of times of welding.  The resistance Rde is computed to precisely judge the quality of welding.

Title: Display device
Inventor: SUMIYA SHIGEAKI
IPC: G06F3/0481
Filed: 1991-01-29
Abstract: PURPOSE:To prevent a cursor from becoming hard to see whatever gradation level data has. CONSTITUTION:On a monochromatic display which displays gray data with 128 gradations 0-127, 0 corresponds to black and 127 corresponds to a highlight. A figure (a) shows an example of an array of original image data and a figure (b) shows an example of data when the arrow-shaped cursor is displayed thereupon while the cursor part is encircled with a thick line. The data with the 128 gradations is 6-bit data in binary notation. The inversion of 1 and 0 of the most significant digit bit of the 6-bit data is equivalent to the addition of 64 when the original image data is 0-60 and the subtraction of 64 when the original image data is 64-127, and the absolute value of the difference between the original data and inverted data is always 64 obtained by dividing 128 by 2. Consequently, there is a difference of 64 gradations from the cursor whatever the original image data is, and the cursor is held in an easy-to-see state at all times.

Title: Nonlinear optical element
Inventor: NAKAMURA SHIGERU
IPC: G02F1/35
Filed: 1993-01-22
Abstract: PURPOSE:To provide the nonlinear optical element which suppresses the fluctuation in an impressed static electric field and eliminate the cause for hindering high-speed operation by note only holding a large element capacity but decreasing sweeping current as well. CONSTITUTION:A reverse bias voltage is applied between electrodes 1 and 11 and the static electric field is impressed to the striped charge part, i.e., photoconductive region, of a GaAs core layer 5. The electrodes 1 and 9 are held shorted from each other and the static electric field is substantially not impressed to the parts exclusive of the photoconductive region of the GaAs core layer 5. Control light pulses are absorbed in the GaAs core layer 5 and carriers are formed, by which a nonlinear refractive index change is generated. The carriers of the striped charge part among these carriers are swept and the nonlinear refractive index change is restored. The signal light propagating in the photoconductive region of the element is subjected to phase modulation by this nonlinear refractive index change. On the other hand, the carriers formed in the parts exclusive of the striped charge part of the core are not swept.

Filed: 1996-01-23
Abstract: PROBLEM TO BE SOLVED: To improve conversion efficiency, regardless of materials used in the structure, by forming a plurality of first or second conductive type pillar- shaped microcrystals buried in an undoped semiconductor layer. SOLUTION: A pin junction-type solar battery has a plurality of pillar-shaped microcrystals 14 buried in an undoped GaAs layer 16. In this way, because of the buried microcrystals 14 in the undoped GaAs layer 16, a depletion layer has a width of W+h in a certain place of the microcrystal, where W is the width of the pin junction and h is the height in a vertical direction of the junction, so the width of the depletion layer is substantially increased. Then, all the carriers generated when light is made incident on the junction are collected. The spectrum response in the solar cell is increased and the conversion efficiency is increased.

SOLUTION: The displacement amount of a thermocompression bonding means 50A caused by thermal expansion is measured. Then, based on the measuring result, so as to correct the displacement amount of the thermocompression bonding means 50A caused by thermal expansion, one surface 1A where an electrode part 1B of electronic parts 1 are provided is submerged in a bonding agent bath 56 where a bonding agent 2 is housed, so that the bonding agent 2 is transferred to the one surface 1A of electronic parts 1. After that, with the electronic part 1 positioned/mounted to an interconnection substrate 5, the electronic parts 1 are thermocompression-bonded to the interconnection substrate 5.  For example, a bare chip 1 sucked to a heating/ sucking tool 50A, in that state a displacement measurement device 60 is moved to directly below the bare chip 1, to measure the displacement amount of the heating/ sucking tool 50A due to thermal expansion.

Abstract: PURPOSE:To obtain the display element having a high reflectivity and good scattering degree by specifying the orientation direction on at least one substrate of the display element constituted by orienting and dispersing liquid crystals and high polymers to each other to >=2 directions and incorporating multichromatic dyestuff into the display element. CONSTITUTION:The orientation direction at least on one substrate of the display element constituted by subjecting the substrates 4, 11 formed with electrodes 5, 10 to orientation to orient and disperse the liquid crystals 8 and the high polymers 7 to each other and clamping these liquid crystals and high polymers are specified to >=2 directions. The display element contains the multichromatic dyestuff. The electrodes 5, 10 are first formed by a vapor deposition method on the surfaces of the substrates 4, 11. Oriented films 6, 9 are applied by spin coating on the surfaces of these substrates 4, 11 and are baked. The surfaces of these oriented films 6, 9 are thereafter rubbed. Further, the films are rubbed again in the direction orthogonal therewith in a manner as not to erase the previously rubbed orientation. A mixture formed by mixing high-polymer precursors and the liquid crystals is sealed into the spacing between the substrates 4 and 11 and is oriented. As a result, the reflectivity at the time of electric field impression is improved and further, the dependency on visual sensation is improved.
