IPC: G02F1/13
Filed: 1987-07-31
Abstract: PURPOSE:To prevent the advance of air and adhesive agent into a cell and to prevent the degradation in display performance by reducing the pressure in the empty cell having one aperture, injecting liquid crystal and the adhesive agent continuously into the cell and curing the adhesive agent in the aperture before the adhesive agent flows into the cell. CONSTITUTION:The pressure in the empty cell 1 is reduced to a negative pressure in a pressure reduction stage. The negative pressure or reduced pressure state is maintained in the cell 1 and the liquid crystal 11 and the adhesive agent 12 are injected into the cell in an injection stage. The injection is stopped and the adhesive agent 12 is cured at the point of the time when the adhesive agent 12 arrives at the aperture 3. The sealing of the aperture 3 is executed and the advance of the adhesive agent into the cell 1 is prevented at this point of the time. The curing time is short if the adhesive agent 12 is of a UV curing type and, therefore, the sure sealing in the aperture 3 is executed. The generation of a defective display by the intrusion of the adhesive agent is thereby obviated.

Title: Semiconductor light receiving element
Inventor: TAKANO TOMOAKI
IPC: H01L31/108
Filed: 1991-07-09
Abstract: PURPOSE:To reduce the leakage current of a light receiving element formed in an optoelectronic integrated circuit and make the construction of the element most advantageous to the manufacture. CONSTITUTION:One of a pair of metal electrodes to be formed on a GaAs substrate 1 is a Schottky electrode 4; the other is an ohmic electrode 3 formed on a p-type layer 2, an impurity diffusion region. Since the p-type layer 2 is formed on the ohmic electrode 3 side, the electron current, the major component of the leakage current, is controlled by diffusion, not the thermal radiation from the Schottky barrier, being reduced. Since the p-type layer 2 is formed only on the ohmic electrode 3 side, the number of processes is not increased and remarkable increase in the area of occupation is suppressed.

Title: Bus arbitration device and method therefor
Inventor: YAMADA SHINKO
IPC: G06F13/362
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To optimize the priority of requesting sources by adjusting the priority by guaranteeing the maximum waiting time for all requesting sources by shortening the time required until permission is given to a specific requesting source after the source makes a bus using request. SOLUTION: A grouping means 115 collects requesting sources for which the time required until permission is given to the sources after the sources make requests must be shortened into one group and another requesting sources which make the other request than refreshing requests into another group. A priority changing means 116 changes the priority of non-grouped requesting sources to the lowest rank when the requesting source obtains permission and, when grouped requesting sources and refreshing requesting sources obtain permission, the means 116 changes the priority of the former to the lowest priority and to another priority which is higher than the lowest priority by one rank. Therefore, a specific requesting source does not keep a bus to itself and the time until permission is given to a requesting source after the source makes a request is shortened. A group order changing means 118 guarantees the maximum waiting time of all requesting sources by changing the priority of a permission requesting source to the lowest rank. The balance among the priority of all requesting sources is optimized by changing the priority based on the results of a measuring means 119 which measures the number of permission given to the requests from the groups.

By using the spherical nickel hydroxide with smooth surface, the filling density is improved as compared with that in the case nickel hydroxide with irregular shape is used. Moreover, it is preferable that a hydrogen storage alloy MnNi5 containing mixed metal is used for the negative electrode material.  Further, a finely porous substance, having smaller pore diameter than the minimum particle size of the nickel hydroxide, is used as a separator.
