Title: Electric discharge machining control device
Inventor: MUTO KAZUO
IPC: B23H1/02
Filed: 1987-01-23
Abstract: PURPOSE:To aim at preventing concentrated electrical discharge by providing AE sensors on an electrode and a workpiece to measure the position of electrical discharge at predetermined time intervals on a real time base during electrical discharge machining so as to monitor whether or not the electrical discharge is carried out at one and the same position or in the vicinity thereof. CONSTITUTION:Signals from SE sensors S1, S2, S3 are led to the corresponding logic elements f1, f2, f3, respectively, through a circuit composed of an amplifier (a), a diode (b), a battery (c), a comparator (d), a diode (e) and the like. These three logic elements pass clock signal therethrough and delivers these to an AE signal arrival time measuring counter i1, i2, i3 until the AE signals arrives. In this arrangement, one set of data per predetermined machining time is extracted and is delivered to a computer. Further, when the computer determines that the electric discharge is carried out at one and the same position or in the vicinity thereof, the computer at once controls the electrical discharge so that the position of the electric discharge is displaced, thereby it is possible to prevent concentrated electric discharge.

Filed: 1990-01-25
Abstract: PURPOSE: To improve the yield in the continuous production of isobutyric acid by Koch synthesis from propylene, carbon monoxide, and water by mixing propylene newly fed with a specified amt. of carbon monoxide and introducing the mixture into a reactor.  
     CONSTITUTION: Isobutyric acid is continuously produced from propylene, CO, and water or a lower alkanol by continuously introducing a liq. and gaseous starting material contg. a gas mixture of propylene and CO into a pressurized reactor 1 under pressure in HF as a Koch catalyst and by depressurizing a liq. and/or gaseous reaction mixture continuously discharged from the reactor 1 and recirculating HF and unreacted CO to the reactor 1. In this process, 1 mol of propylene newly fed is mixed with at least 1.5 mol of CO, pref. recirculated CO, freed of HF by cleaning with an absobent liq., esp. water or isobutyric acid, and having an HF content lower than 5 mol.% before being introduced into the reactor 1. Thus, the yield of butyric acid is improved.

Filed: 1993-01-29
Abstract: PURPOSE:To obtain a surface acoustic wave resonator suitable for configuration of a filter by providing a substrate, an electrode group in which two interdigital electrodes or over are connected in series, and a capacitive element connected in parallel with the electrode group. CONSTITUTION:A ladder filter is configured by forming a conductive thin film on the surface of a piezoelectric substrate 3 and forming a bonding pad 6 to connect an interdigital electrode 4 and a capacitive element 5 or an electrode pattern and a package terminal being components of the surface acoustic wave resonator. That is, three one-aperture surface acoustic wave resonator 4 are connected in series and the capacitive element 5 is connected in parallel with the surface acoustic wave 4 connected in series. Through the constitution above, the capacitance required for the adhesive condition is obtained by a sum of a damping capacitance of the surface acoustic wave resonator 4 and the capacitance of the capacitive element 5 and the damping capacitance required from a loss is obtained by a capacitance of the single surface acoustic wave resonator 4. Thus the respective requirements are easily satisfied and the freedom of the design is increased.

Title: Memory device
Inventor: HATTORI MASAYUKI
IPC: G06F11/10
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To increase a code length and obtain high error correction efficiency with a small volume of redundant data. SOLUTION: An input data Din which is one-byte (8-bit) data is supplied to an encoder 12. The encoder 12 converts the input data Din to an SSRS code(subspace, subcode of read solomon code) (one symbol = 8 bits, information 512 symbols and redundant data 5 symbols) as a write data WD. The write data WD from the encoder 12 is converted by a converter 13 to a 4-bit data and supplied to a cell array 11. The data is sequentially written to each cell. At the read time, a decoder 15 returns the SSRS code as a read data RD to a read solomon code (one symbol = 10 bits, 2 error correctable shortened read solomon code of 517 symbols), subjects the code to error correction and obtains 8-bit data as an output data Dout. Since the SSRS code is used as an error- correcting code, a code length is increased in comparison with the case of, e.g. the read solomon code.
