IPC: G02B6/124
Filed: 1987-09-04
Abstract: PURPOSE:To obtain the integrated optical element with high light utilization efficiency, by providing an intermediate layer which has a lower refractive index than a planar optical waveguide layer between a planar optical waveguide layer where light from a light source is incident and a planar optical waveguide layer which supplies light to a photodetector among >=2 planar optical waveguide layers provided on one substrate to shift the light. CONSTITUTION:When the light from the light source 11 is incident on at least one planar optical waveguide layer 3 among >=2 plane optical waveguide layers 3 and 5 provided on one substrate 1, the incident light is propagated in the planar optical waveguide layer 3 and a part of it is propagated to other planar optical waveguide layers 5 for supplying light to the photodetector 12. Then the optical element provided on at least one of the two kinds of planar optical waveguide layers 3 and 5 put the light propagated in the planar optical waveguide layers 3 and 5 in target operation. Therefore, the light beam put in the difference operation by the optical element are guided to the difference planar optical waveguide layers 3 and 5 and never pass through the same optical element repeatedly and unnecessarily. Consequently, the utilization efficiency of the light is high and many optical elements can be integrated.

Filed: 1999-08-05
Abstract: PROBLEM TO BE SOLVED: To synthesize an excellent response, high quality voice by dynamically cutting out a waveform from a first signal, extracting characteristic information, generating a coefficient, convolution operating it to a second signal and generating the synthetic signal. SOLUTION: A digital signal processor 2-1 performs control of voice pressure and correction of tone quality to the voice signal, and cuts out the voice waveform at a prescribed interval so as to become the coefficient sent to a convolution circuit 3. The digital signal processor 2-2 performs the control of voice pressure and the correction of tone quality to an instrumental sound signal to transfer them to the convolution circuit 3 as the data. The convolution circuit 3 convolution operates these outputs as the data. The coefficient cut out with the digital signal processor 2-1 is stored in a memory RAM 4 for the present, and is switched to the convolution circuit 3 by the control of the CPU 5 to be supplied. The output of the convolution circuit 3 is applied with the effect such as the correction of the tone quality and the echo by the digital signal processor 6, and is inversely converted to an analog signal by a DA converter 1 to become the synthetic voice output.

Title: Password collation system
Inventor: MIYASHITA AKIRA
IPC: G06F21/32
Filed: 1989-08-31
Abstract: PURPOSE:To attain the use of an optional password with no limitation of the character types and the number of characters by converting an input password into a character code and applying a prescribed operation to the character code for acquisition of a password of the fixed length. CONSTITUTION:Each character of a password inputted via a keyboard 5 is converted into a character code by a character code conversion part 6. A fixed length password arithmetic part 7 applies a prescribed operation to each character code to acquire a fixed length password of 2 bytes (hexadecimal 4 digits). Then the display or non-display of the supplement data is decided based on the registration and the collation of the fixed length password. As a result, an operator can use an optical way-to-memorize password with no limitation of the character types and the number of characters. In addition, the information is never stolen nor destroyed by the outsiders since no limitation is applied to the character types and the number of characters. Thus the information can be stored with higher safety.

Title: Method for forming element isolation region
Inventor: YONEHARA TAKAO
IPC: H01L21/76
Filed: 1985-10-07
Abstract: PURPOSE:To enable a very small element isolation region to be formed and improve the element characteristics by providing a material of higher nucleation density at least in the bottom surface portion of an element isolation groove to selectively burying the semiconductor material into the element isolation groove, thereby eliminating the need for planarization by etching. CONSTITUTION:A substrate 1 of silicon is coated with resist 2, and after removing the resist on the portion of the element isolation region, with the remaining resist 2 as a mask a groove 3 is formed on the substrate 1 by means of reactive ion etching. Then, a SiO2 layer 4 is formed by means of thermal oxidation on the surface of the substrate 1 and in the groove 3, subsequently resist 5 is provided by patterning on the portion except for the groove 3, and a Si3N4 layer 6 (or amorphous silicon layer) is deposited on the resist 5 and the bottom surface portion of the groove 3. Then, the resist 5 is peeled off, allowing only the Si3N4 layer 6 on the bottom surface portion of the trench 3 to remain. Thus, when silicon is deposited under a certain deposition condition, it is not deposited on the SiO2 layer 4, but silicon which is not amorphous is selectively deposited on the Si3N4 layer 6. Therefore, silicon 7 which is not amorphous is deposited only in the groove 3, filling up the groove 3.

Filed: 1991-09-04
Abstract: PURPOSE:To generate a procedure using repetitive expression as a procedure for calculating the differentiation of a calculation procedure including total sum calculation and total product calculation by embedding the generated calculation procedure in a fixed calculation procedure in advance and generating it. CONSTITUTION:An element of a variable (x) and a variable which varies in value when the value of the variable (x) varies are extracted from a part which is repeatedly calculated in the total sum calculation or total product calculation (step 101). Then differentiation by the element of the variable (x), extracted in the step 101 for the part which is repeatedly calculated in the total sum calculation or total product calculation, and other variables is generated (step 102). Then a calculation procedure is generated by embedding the differentiation generated in the step 102 and other information regarding the total sum calculation or total product calculation in the fixed calculation procedure in advance (step 103). Therefore, a procedure for calculating the differentiation can be generated from the calculation procedure including the total sum calculation or total product calculation. The generated calculation procedure represents all parts to be looped as loops and can perform respective repetitive calculations independently.

Title: Transistor drive circuit
Inventor: TSUZUKI KUNIYUKI
IPC: H02M3/00
Filed: 1988-09-06
Abstract: PURPOSE:To improve the reliability of driven circuit by producing OFF pulse of a pulse transformer not with fixed length but in proportion to ON pulse. CONSTITUTION:ON pulses produced from an ON pulse generating circuit 1 drive the primary winding 17 of a pulse transformer 13 through an ON pulse drive circuit 11 and bias the base-emitter of a transistor 14 forwardly through the secondary winding 18 to operate a driven circuit 15. Since no OFF pulse can be obtained from an AND gate 8 when the ON pulse is very short, a specific minimum OFF pulse is produced from the trailing edge of the ON pulse through a one-shot multivibrator 9, then the minimum OFF pulse is ORed with the output from the AND gate 8 through an OR gate 10 to produce an OFF pulse. Then an OFF pulse drive circuit 12 drives the primary winding 16 of the pulse transformer 13 to bias the base-emitter of the transistor 14 reversely so as to stop the driven circuit 15.
