Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To make a flat display structure formed by mutually laminating a plasma address type display panel and a back light for illuminating this display panel from the back thin in thickness. SOLUTION: A display panel 1 has a laminated structure formed by mutually laminating an electro-optical cell 3 and a plasma cell 4. A sealing part 5 is protruded from under the plasma cell 4.

Title: Preparation of glass base material for planar optical waveguide and planar optical waveguide
Inventor: BENKATA ADEISESHIYAIAA BAAGABA
IPC: G02B6/13
Filed: 1991-12-10
Abstract: PURPOSE: To lessen optical loss by composing a glass preform of first glass having a first refractive index and second glass having the refractive index different from the first refractive index and to reduce a cost by combining improved optical performance with the capability for mass production. CONSTITUTION: One or more layers having the refractive index different from the refractive index of a substrate 1 are affixed to the surface of this substrate 1, by which a barrier layer 4, a core layer 5 and a clad layer 6 are formed. If the difference in the refractive index between the substrate 1 and the core layer 5 is too small, the material of the barrier layer 4 is so selected that the difference in the refractive index between the substrate 1 and the core layer 5 is sufficient for channeling of the greater part of the light incident on the planar optical waveguide through the core layer 5. Next, the structure, after attached with the materials, is heated in a furnace in order to form a planar optical preform by melting the materials to induce the refractive indices and is stretched in order to form a planar optical cane having the preselected final size. Preselected optical circuits are formed on the planar cane by using a lithographic technique.

IPC: G01R31/26
Filed: 1991-12-10
Abstract: PURPOSE:To carry out an effective high temperature accelerated life test at a higher temperature and more promptly by connecting an additional circuit, which has a broad temperature range for normal operations and also functions substantially equivalently to an input/output buffer circuit, in parallel with a normal input/output buffer circuit, and by using this additional circuit at the time of a high temperature accelerated life test. CONSTITUTION:A semiconductor integrated circuit 1 is provided with a first circuit element 2 which operates normally under a high temperature environment in which an accelerated life test is performed, a second circuit element which operates abnormally under a high temperature environment, and also an additional circuit element 4 which operates normally under a high temperature environment. At the time of a high temperature accelerated life test, since a resistance value of an element Q becomes relatively low, an output signal from the first circuit element 2 is coupled to a following stage via the additional circuit element 4. The second circuit element 4 operates normally even in a high temperature range, and hence the temperature of a high temperature accelerated test can be increased into a range in which the first circuit element 2 that operates normally at a high temperature can operate, whereby a high temperature accelerated life test can promptly and effectively be carried out.

Title: Switching power source device
Inventor: HAGA HIROYUKI
IPC: H02M3/28
Filed: 1991-12-09
Abstract: PURPOSE:To provide a low-loss and low-noise switching power source by connecting a second switching element, which is turned on or turned off synchronously with the first switching element connected to the primary winding of a transformer, to the secondary winding of the transformer, and providing the second switching element with bidirectional on-off function, and performing zero voltage switching. CONSTITUTION:When a first switching element 3 is turned on, voltage occurs in the secondary winding 2b of a transformer 2, and it transmits energy from the primary side of the transformer to the secondary side through a second switching element 9, and at the same time, it accumulates energy in the transformer 2. Next, when the first switching element 3 and the second switching element 9 are turned off, the secondary winding voltage of the transformer 2 does not become zero suddenly, accordingly the voltage VDS of the first switching element 3 rises slowly, and reduces the loss at off and the noise at off. Next, when turning on the first switching element 3, the loss at on and the noise at on are reduced by performing the zero voltage switching.
