Abstract: PURPOSE: To provide a circuit which is small-sized and has a high processing capability by using specific formulas I and II to perform the data processing of DCT caused between the table of N×M data f(x, y) and a table of M×N coefficients (u, v). CONSTITUTION: In the formula I, K is a constant-power of 2, and x, y indicates coordinates of data in the data table, and u, v indicates coordinates of coefficients in the coefficient table. In the formula II, c(u), c(v) is 1/2<1/2> for u, v=0 and is one for u, v≠0. Each coefficient F(u, v) is successively determined even for a pair of coordinates u, v, and the absolute value and the sign of a coefficient P=p(x, u), p(y, v) are searched in the table for a first pair of x, y. When the absolute value of P is multiplied by f(x, y), the result of multiplication is introduced to an accumulator by addition or subtraction with the function of the sign. An operation is restarted for all values of the pair x, y, and the result given by the accumulator is extracted.

IPC: H01L21/302
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To suppress retreat of a mask pattern so as to improve the shape stability and dimensional stability when a contact hole is subject to etching through a mask pattern that is provided with an opening smaller than the resolution limit of a photo lithography. SOLUTION: An opening 9h is formed in a polysilicon film on an interlayer insulation film 8 through a photo lithography, and a side wall for mask is formed within the opening 9h through entire accumulation of another polysilicon film and etch back. The polysilicon film is polished chemically and mechanically to reduce its film thickness, and the obtained polysilicon film 9pt for mask and side wall 11st for mask whose sectional shape is almost square are used as a mask pattern. Since the pattern edge comes close to the vertical wall, the incident probability of ion from plasma into the edge becomes lower and the retreat of edge due to ion sputtering can be prevented.

Title: Apparatus for converting text to voice speech
Inventor: DENISU HAUAADO KURATSUTO
IPC: G06F3/16
Filed: 1984-12-12
Abstract: The present system employs a microprocessor to accept ASCII signals representing text and transforms the same into coded signals representing phonemes, according to Hunnicutt rules for such transformation. The microprocessor is programmed to generate a plurality of parameters (16 bit values every 6.4 milliseconds in a preferred embodiment) in accordance with the phoneme sequence for the text. The parameters, which include mathematical considerations of the phoneme properties, are transmitted to a high speed digital signal processor whereat they are used to control multiplications and additions in doing programmed simulations of certain equations, thereby providing a digitized glottal waveform. The digitized glottal waveform at the step of the operation includes sufficient information to provide 40,000 samples per second, in a preferred embodiment. Thereafter the high speed digital signal processor subjects said digitized glottal waveform to a programmed low pass filtering operation to remove components of signals having frequencies in excess of five kilohertz and to provide some averaging of temporally adjacent values. Next the present system subjects the low pass filtered, digitized glottal waveform to down sampling, in a preferred embodiment, at the rate of 10,000 samples per second. The down sampled digitized waveform is then combined, under the guidance of a program, with a digitized waveform of aspiration sounds and then filtered by a set of digital resonators and this filtered combination is further combined with a waveform representing frication sound. This last described digital waveform is transmitted to a digital to analog converter to provide an analog waveform (spoken version) of the text.

The PP 12, after activating the CP 13, prepares a data of next one page content without waiting completion of operation of the CP 13. After preparing the data of one page content, the CP 13 is again activated. In the case where the CP 13 yet performs a before page treatment, the document data is enqueued and on completion of the before page treatment, treatment of the next page is performed without ending the procedure.

Title: Optical transmission equipment
Inventor: TSUKAGOSHI TAKASHI
IPC: H04B10/03
Filed: 1987-10-16
Abstract: PURPOSE:To operate a line of the normal device side while preventing any danger to be inflected on a human body by decreasing a laser output level in the event of disconnection of optical fiber, and sending optical input interruption information as sub information together with a main signal. CONSTITUTION:If a fault of a broken optical fiber occurs at a point C of a transmission line 21 from a station A to a station B, an optoelectric conversion section 1' of the station B generates an optical input interruption alarm signal 13'. This signal together with the sub information signal 15' is multiplexed and sent to the station A while being superimposed on the main signal by a CMI coding section 5'. Moreover, the optical output level from the station B is decreased by using an optical output control signal 14'. Then the station A detects an alarm signal of the station B at a sub information demultiplex section 3 and uses an optical output control signal 14 to decrease the optical level of the station A. Furthermore, if both transmission lines are broken, the optical output level is decreased by using an optical input interruption alarm signal of its own station. Thus, danger to human body is prevented and the circuit of the sound system is operated.

Title: Start time fuel injection control device of internal combustion engine
Inventor: NISHIGUCHI HISAO
IPC: F02D41/06
Filed: 1989-10-06
Abstract: PURPOSE:To prevent any knocking phenomenon and starter lock phenomenon so as to improve low-temperature startability by operating a control device only during the starting period, changing the preset crank angle in response to the engine temperature, and performing asynchronous injection with a fuel injection valve at the crank angle with the slower timing at the high temperature than that at the low temperature. CONSTITUTION:An asynchronous injection control means 16 is operated only during the starting period by the detected signal from a starting period detecting means 14 to change the preset crank angle in response to the engine temperature detected by a temperature detecting means 15, and asynchronous injection is performed by a fuel injection valve 13 at the crank angle with the slower timing at the high temperature than that at the low temperature. The atomization of fuel is boor at the low temperature of an internal combustion engine 11, thus asynchronous injection is performed at the crank angle of early timing by the control means 16, and the combustible mixture is generated at the early timing. On the other hand, asynchronous injection is performed at the crank angle with the slow timing at the high temperature of the engine 11, thus the combustion is prevented, at the timing where the cranking rotation is not sufficiently increased yet immediately after the engine start.
