Patent JP-H114227-A (JP)
Title: Band sharing circuit and transmission system
Inventor: YOSHINO MANABU
IPC: H04L12/28
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To minimize a cell abandonment with little buffer amount by supervising a difference between the cell amount stored in a cell buffer circuit and a set threshold, informing an information source which transmits an information cell to limit a cell transmission and adjusting the amount of information cell to be transmitted. SOLUTION: An information cell stored in a cell buffer circuit 11-1 is successively read and outputted from a band sharing circuit. On the other hand, a supervisory means 12-1 supervises the amount of cell stored in the cell buffer circuit 11-1 and, when the amount of cell exceeds the first threshold set, the supervisory means informs a cell generative means 13-1. The cell generative means 13-1 responds to this information, generates a limitation information cell for informing an information source which transmits an information cell to limit a cell transmission and gives it to a cell insertion means 14-1, while the cell insertion means 14-1 descends this limitation information and inserts in an output circuit.

Title: Forming method of polycrystalline semiconductor film
Inventor: SANO KEIICHI
IPC: H01L21/316
Filed: 1993-05-31
Abstract: PURPOSE:To enhance the grain diameter in a polycrystalline semiconductor film by a method wherein a heat-shrinkable film which shrinks at a thermal treatment temperature is provided onto an amorphous semiconductor film or between a substrate and an amorphous semiconductor film. CONSTITUTION:An intrinsic amorphous silicon film 2 is formed through a plasma CVD method on a substrate 1 high enough in heat resistance to the crystallizing temperature of amorphous silicon. Then, a heat-shrinkable film 3 of SiO2 is formed through a normal pressure CVD method, and the substrate 1 is thermally treated at a temperature higher than a crystallizing point of 500 deg.C in an electric oven. Then, the heat- shrinkable film 3 is shrunk to produce a compression stress on the surface of the amorphous silicon film 2. For instance, an SiO2 film formed through a normal pressure CVD method is reduced in volume by 5% or so when it is annealed at a temperature of 600 deg.C for two hours. On the other hand, an amorphous silicon film is reduced in volume by 0.2% or so. A compression stress is produced on the surface of an amorphous silicon film due to this shrinkage factor difference between them. In result, nucleation are controlled in an amorphous silicon film, and the solid phase growth of silicon takes place in a single direction from a substrate to the surface of an amorphous silicon film, so that polycrystalline silicon can be enhanced in grain diameter.

IPC: G02F1/133
Filed: 1986-07-03
Abstract: PURPOSE:To obtain a clear picture which is free from display unevenness over the whole area, by providing a low-resistance metallic film which is formed in such a way that the film is brought into contact with stripe-like transparent electrodes in parallel with the electrodes and covers the inter-electrode spaces. CONSTITUTION:Rays of light are intercepted at the inter-electrode spaces of stripe-like transparent electrodes 2 formed on a base plate 1, by forming a metallic film 3 in such a way that the film 3 is contacted with the electrodes 2 in parallel with the electrodes 2 and covers the inter-electrode space sections A. A cell is obtained by arranging two such base plates in such a way that the electrodes of each base plate can be faced to each other and interest each other at right angles and enclosing ferroelectric liquid crystal in the space between the base plates. Since the inter-electrode spaces are covered with the low-resistance metallic film 3, the area where the two stable states of the ferroelectrid liquid crystal exist can be eliminated and, moreover, the inter- electrode spaces can be intercepted from light. Therefore, unevenly oriented states of liquid crystal can be eliminated and a clear picture can be obtained.
