Title: Device for estimating machine constant of driving machine
Inventor: IKEDA HIDETOSHI
IPC: G01M1/10
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To reduce an estimation error due to disturbance torque such as clone friction and to estimate machine constants highly accurately by assigning a relatively small weight immediately after starting a driving machine based on a weighting signal, and then calculating the estimation value of the machine constants. SOLUTION: A weighting signal generation part 7 inputs a machine speed Vm, and generates a weighting signal wt of a smaller level until specific time passes after a driving machine 3 starts from a still state. A machine constant estimation part 8 integrates a weighting signal wt to a transition torque signal τf and a transition acceleration signal af, obtains a weighted torque signal τw and a weighted acceleration signal aw, and performs updating so that an inertia estimation value Je that is a machine constant of the driving machine 3 approaches a ratio to a weighting acceleration signal aw of a weighted torque signal τw at the least square operation part. In this case, since the weighting signal wt is made relatively small immediately after starting, the inertia estimation value Je is gently updated immediately after the start of the driving machine 3.

Title: Microwave plasma generator
Inventor: HASHIMOTO KIYOSHI
IPC: H01L21/302
Filed: 1994-05-30
Abstract: PURPOSE:To extract a large-density plasma of an approximately uniform density distribution or beams by arranging three magnets in such a way that they surround a discharge container and are spaced apart from each other along the direction of extraction, then magnetizing each permanent magnet along a direction perpendicular to the direction of extraction, and causing the adjacent magnets to have opposite polarities to each other. CONSTITUTION:Permanent magnets 23-25 are provided on the external wall surface of a discharge container 22 in such a way as to surround the wall surface and to be spaced apart from each other along the direction of extraction, and are magnetized in a direction in which the adjacent magnets have opposite polarities to each other, and also in a perpendicular direction (horizontal direction) to the direction in which the magnets are spaced apart from one another. The magnet 25 is provided near an opening 26 in the lower end portion of the container 22. Therefore magnetic lines 27 of force are formed across the adjacent magnets within the container 22; i.e., the magnetic lines 27 of force generated by the magnets 23, 24 within the container 22 are strong and bulge toward the center. The magnetic lines 27 of force generated by the magnets 24, 25 within the container 22 are small in length along the direction of magnetization of the magnet 25 and so bulge less at the center. Therefore, a 875-gauss magnetic field exists in a portion very near the interior wall 2a of the container 22 on which magnets 23, 24 are provided. The intensity of the magnetic field near the center of the container 2 is around 500gauss, which is sufficient to create high-density plasma.

Title: Hearing aid having speech speed conversion function
Inventor: KONDO KATSUFUMI
IPC: G10L21/057
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To provide a hearing aid having a speech speed conversion function that identifies whether or not a picked-up voice is a voice uttered by a carrying person and provides an output as it is without conducting speech speed conversion when the voice is uttered by the carrying person. SOLUTION: A microphone 1 picks up a voice from a carrying person and extracts its characteristic and stores it to a carrying person voice characteristic storage area 13a. When a voice signal is picked up by the microphone 1 after that, whether or not the voice signal is uttered by the carrying person is discriminated based on the characteristic stored in the carrying person voice characteristic storage area 13a and when the voice is uttered by the carrying person, the voice signal is outputted as it is without conducting speech speed conversion processing. On the other hand, when the voice is uttered by a person other than the carrying person, the voice signal is subject to speech speed conversion processing and the resulting signal is outputted.

Title: Semiconductor device and fabrication thereof
Inventor: GESHI TATSURO
IPC: H01L21/28
Filed: 1993-05-19
Abstract: PURPOSE:To protect the wiring layer against oxidation or corrosion even when an silicon oxide (LPD-SiO2) is deposited by liquid phase epitaxial growth as an interlayer insulation film. CONSTITUTION:A tungsten plug 5 is formed and covered with a barrier metal film 6 of TiW and then an LPD-SiO2 film 8 is formed thereon. Consequently, the tungsten plug 5 is not exposed to the atmosphere or the saturated aqueous solution employed in liquid phase epitaxial growth and thereby the tungsten plug 5 is protected against oxidation. A photoresist (PR) film is then formed according to the pattern for forming a tungsten (W) film 7 before the LPD-SiO2 film 8 is formed. The PR film is then removed and the W film 7 is formed in the recess which is made according to the pattern for forming the W film 7 on the LPD-SiO2. Since the LPD-SiO2 film 8 is not formed after formation of the W film 7, the W film 7 is not exposed to the atmosphere or saturated aqueous solution and thereby protected against oxidation.

Title: Automatic lead feed mechanical pencil
Inventor: YAMADA HIROSHI
IPC: B43K21/033
Filed: 1989-05-10
Abstract: PURPOSE:To obtain a mechanical pencil in which next lead piece can be automatically fed even after one lead piece is consumed by disposing a lead out feeder at the rear of a lead feeder, i.e., at a position farther than a sheet surface from the lead feeder. CONSTITUTION:When a lead pressing force is operated at the rear of a mechanical pencil from a sheet surface by a writing operation to move a lead feeding cylinder 15 rearward against the operation of an elastic member 18, the cylinder 15 is moved rearward by the wedge operation of a ball 16 to compress the member 18. Simultaneously, when a lead feeding roll 8 is released from a protrusion 19 to release a tightening holding of a lead thereby to rotate it, a writing operation is finished at one stage to raise the lead from the sheet surface, and the pressing force to the lead is released, a holding cylinder 7 is moved forward by the elastic recovery force of the member 18. In this case, since the roll 8 is reversely rotated to hold the lead, the lead can be fed into the cylinder 15 for allowing the lead to move forward only.

Title: Production of dichloroacetaldehyde trimer
Inventor: ISHIZUKA MAKOTO
IPC: C07C47/14
Filed: 1990-05-07
Abstract: PURPOSE:To obtain the subject compound useful as a raw material for pharmaceuticals and agricultural chemicals in high yield and purity on an industrial scale at a low cost by carrying out the dehydrative cyclization of hydrated dichloroacetaldehyde in the presence of concentrated sulfuric acid. CONSTITUTION:The objective dichloroacetaldehyde trimer can be produced by the dehydrative cyclization of hydrated dichloroacetaldehyde in the presence of concentrated sulfuric acid. The dehydrative cyclization is carried out by adding the hydrated dichloroacetaldehyde to 5-15 times weight of 95-99% sulfuric acid cooled to -20 to +20 deg.C. The process does not require particular chlorination step to decrease the impurity monochloroacetaldehyde content in dichloroacetaldehyde to eta1% which is essential in a process using a metal chloride as a trimerization catalyst. Furthermore, the process is advantageous because it does not use a catalyst such as antimony trichloride nor discharge a hardly disposable waste material.

IPC: H03K19/21
Filed: 1984-06-07
Abstract: PURPOSE:To prevent malfunction due to an unnecessary pulse by inhibiting the output of a comparator comparing the value of a rotary switch and a counter while the value of a switch detection circuit detecting a value ''2'' of the rotary switch is reserved. CONSTITUTION:Ahead the operation of the rotary switch SW1, an SW6 is thrown to the position SET, and after the SW1 is operated in positions 1-5 in order to set ''5'' by the SW1, the SW6 is thrown to the position NOR. The digital value of the SW1 is inputted to a comparator 3, and when the value from the counter 2 is equal to a value of the SW1 at the comparator 3, a coincidence detecting signal (a) is outputted to a holding circuit 7. When a switch detection circuit 6 detects a value ''2'' of the SW1, a signal (c) is outputted to an FF16 of the circuit 7. The FF16 holds the signal (c) until the SW6 is thrown to the position NOR and the output of the signal (a) from the circuit 7 is inhibited during this period. When the SW6 is thrown to the NOR position, the FF16 is cleared, the signal (a) is outputted from a gate 15, and an unnecessary pulse of value ''2'' is not outputted. When the SW6 to be thrown to the SET position is forgotten, an LED19 is lighted.

IPC: H03H9/145
Filed: 1989-05-09
Abstract: PURPOSE:To improve the resonance characteristic by changing the thickness of a dielectric film formed on a surface wave drive electrode and also the thickness of a dielectric film formed on a reflecting electrode in order to shut up the surface wave energy of a dielectric substrate set under the surface wave drive electrode. CONSTITUTION:An Al film having the fixed thickness of about 1mum is vacuum- deposited on a piezoelectric substrate 1, and a comb-line type drive electrode 2 and the reflecting electrodes 3 and 4 are formed at one time by a photolightographic process. Then these electrodes 2-4 are covered with a dielectric film 5 having different thickness with these electrodes respectively. Thus the surface acoustic wave energy is shut up on the surface of the substrate 1 under the electrode 2. The different transmitting speeds of surface waves are set between parts of comb-line type driving and reflecting electrodes by changing the thickness of the film 5. Thus the energy shut-up effect is increased. Then it is possible to obtain the excellent resonance characteristic free from the spurious resonance.
