Title: I/o buffer optimally interrupting noise with minimum footprint
Inventor: MATTOS DERWIN W
IPC: H03K17/687
Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To allow the buffer to interrupt noise with a minimum footprint by allowing 1st and 2nd transistors(TRs) that receives an input signal change to switch a logic level at an output terminal and that receives no change to be nonconductive, and allowing 3rd and 4th TRs that receives no change in the input signal to keep the logic level at the output terminal and that receives the input signal change to be nonconductive. SOLUTION: A P-channel MOSFET 107 connects to a DC driver power supply Vdddc with less noise and an N-MOSFET 101 connects to a DC driver ground Vssdc which are used in common by AC and DC drivers. Furthermore, N- channel MOSFETs 111, 114 connect to a core ground Vss, P-channel MOSFETs 109, 112 connect to a core power supply Vdd, and substrates of inverters 203, 208, P-MOSFETs 115, 204, 211, N-MOSFETs 101, 102, 105, 108, 111, 113, 114, 116, 201, 205, 206, 209, 212 connect to the ground Vssdc. Then the I/O buffer 300 minimizes a voltage spike from a power supply Vssac receiving much noise.

Title: Optical member
Inventor: TOMITA TAKAAKI
IPC: G02B5/04
Filed: 1987-03-13
Abstract: PURPOSE:To obtain an optical member causing only slight deterioration of transmittance even if a prism having an optical multilayered film formed thereon is bonded to another prism with an ultraviolet rays setting adhesive, by forming a adhesive on an optical multilayered film comprising TiO2. CONSTITUTION:Values of optical film thickness 15 of films comprising TiO2 such as the 1st, 3rd, 5th, 7th, 9th, 21st, 23rd, 25th, 27th, 29th layers, are shifted from lambda0/4, and those of other layers are set at lambda0/4. A protective layer 50 comprising Al2O3 is formed above the optical multilayered film 15, and a prism 12 is bonded to a prism 13 interposing an ultraviolet rays setting adhesive 16-a. By providing an Al2O3 layer to a boundary surface between the optical multilayered film and the bonding layer, deterioration of transmittance is prevented even if an optical member is irradiated with ultraviolet rays using an ultraviolet rays setting adhesive on a supporting base.

Title: Speech recognition method
Inventor: OFU KATSUTOSHI
IPC: G10L15/18
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To provide the speech recognition method in which a high performance continuous speech recognition processes is conducted at a high speed using a highly precise language model. SOLUTION: The method obtains a recognition result by the discrimination/ search having plural stages employing the acoustic model, which discriminates the recognition result from the acoustic features of inputted voices, and the language model, which discriminates the recognition result from the grammatical features. In this case, the first stage search outputs higher ranked N hypotheses of the recognition result, which gives a high evaluation value against the inputted voices, employing simple acoustic and language models (Step S110). While conducting a search in the processes including the second stage, the language model, which is required for the re-evaluation of the candidate outputs that are narrowed down in the first stage search, is beforehand extracted (Step S140).  During the search in the steps including the second stage, high grade acoustic and language models are used to re-evaluated the candidates of the first stage and the condidates having a high evaluation value are made as the recognition result (Step S150).

Title: Quenching method for excessive fluorescent reagent
Inventor: NOKIHARA SEISHI
IPC: G01N33/68
Filed: 1991-02-28
Abstract: PURPOSE:To eliminate disturbance of identification of a peak of an object to be analyzed on chromatography as caused by the excessive existence of a fluorescent reagent by causing an ammonia salt to react with an excessive fluorescent reagent to be used in a fluorescence analysis. CONSTITUTION:A quenching of an excessive fluorescent reagent is performed by causing an ammonia salt to react with the excessive fluorescent reagent to be used in a fluorescence analysis. The fluorescent reagent herein used is, for example, fluorescein isothiocyanate (FITC). The ammonia salt for the excessive reagent is used normally with the concentration exceeding 0.1mol. When the ammonia salt is added to the excessive fluorescent reagent in the sample to react, as mentioned above, it is preferable to heat the reagent at about 55 deg.C normally in view of reactivity. Reaction time is normally sufficient, about 10 minute. By such a treatment, aminofluorescein produced from the excessive FITC does not affect analysis of a compound to be detected even when existing in the sample and the intensity of the fluorescence is half as much as FITC thereby eliminating the need for the removal thereof from the sample.

Title: Optical disc recording carrier
Inventor: TAKEUCHI TAKASHI
IPC: G11B7/00
Filed: 1985-03-27
Abstract: PURPOSE:To uniform the influence of the resistance to the flow of a resin at the molding time by arranging preformat parts indicating address information on a substrate so that they are not arranged in parallel between adjacent tracks. CONSTITUTION:When address pits are arranged in the radial direction an optical disc, the disturbance of flow of the resin generated in the address pit part on the t-th track has an influence upon the address pit part on the (t+1)th track and the transfer capacity of a stamper of the address pit is different between the inner peripheral side and the outer peripheral side as the whole. If positions of preformat parts 7 are shifted from one another in the track direction by, for example, a 1/12 circumference, preformat parts 7 are not arranged in parallel between adjacent tracks to uniform the resistance to the flow of the resin at the molding time as the whole of the disc surface. Thus, the transfer capacity for molding is improved to attain the structure of the optical disc superior in mass productivity.
