Title: Apparatus for producing dimethyl ether utilizing organic waste
Inventor: ONO SHIGEKI
IPC: B01J23/755
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To obtain H2 required to fix CO2 at a low cost, convert the CO2 into dimethyl ether using the H2 and fix the CO2 . SOLUTION: A produced gas containing CH4 or CO2 is produced by anaerobic fermentation, etc., of an organic waste in an apparatus 1 for treating the organic waste and the resultant produced gas is then fed to a part 2 for separating and enriching methane. The CH4 is purified from the produced gas by passing the produced gas through the part 2 for separating and enriching the methane and then decomposed into carbon (C) and H2 in the presence of a catalyst in a part 3 for decomposing the methane. The H2 produced in the part 3 for decomposing the methane is then fed to an apparatus 4 for producing dimethyl ether to react the CO2 with H2 in the presence of a catalyst to synthesize the dimethyl ether (CH3 COCH3 ), which is further passed through a condensor 5 to thereby condense the resultant gaseous dimethyl ether. The condensed dimethyl ether is then separated from steam (H2 O).  Thereby, the liquid dimethyl ether is produced.

Title: Three-phase batch voltage detecting method and detection electrode for voltage detector
Inventor: OBARA AKIO
IPC: G01R15/14
Filed: 1987-02-10
Abstract: PURPOSE:To enable three-phase batch voltage detection at low cost by forming electrodes which differ in size and making the phases of the electrodes common all together. CONSTITUTION:Detection electrodes 22u-22w for three phases are arranged between charging parts 21 for the respective phases and the ground 23 and led out of a container by a conductor 24 insulated from the ground 23 so that the three phases are put together; and a relay is operated through an amplifier 25 to transmit the charging and discharging states of the charging parts 21 to the outside. Here, only the diameter phiB of the electrode 22v for a V phase among the electrodes 22u-22w is made larger than the diameters phiA of the electrodes 22u and 22w for a U and a W phase. Further, the distances E between the charging parts 21 and respective electrodes 22u-22w or the distances F between the electrodes 22u-22w and the ground 23 are equalized to enable secure voltage detection in any of cases of the charging of all the three U-W phases, the charging of only the U, V or W phase, and the charging of the respective U-W phases.

Title: Scan control circuit
Inventor: OKADA HISAO
IPC: G01N29/26
Filed: 1989-02-08
Abstract: PURPOSE:To enable simplification of a variable opening control for scanning with a fine ultrasonic beam and inspection with uniform resolutions from a short to long range by building up a scan control circuit with a shift register. CONSTITUTION:A bit pattern for selecting 8 elements and a bit pattern for selecting 5 elements are set on a shift register 1 alternately per bit. At this point, the center of an ultrasonic beam is between fourth and fifth of elements 3. Then, when a shift lock is applied to shift the contents of the register 1 by one bit to the right, the bit pattern for selecting 5 elements is outputted as element selection signal. At this point the center of the ultrasonic beam is at the fifth of the elements, meaning a shift of the center of the beam by a half of an element pitch from the preceding state. Thereafter, likewise, the center of the beam is shifted by a half of the element pitch as a the contents of the register is shifted by one bit. Thus, the use of a scan control circuit enables finer scanning than the element pitch.

Abstract: PURPOSE:To inhibit a parasitic effect, and to reduce a malfunction and the possibility of breakdown by bringing the potential of a second conductivity type region to the same potential as a first conductivity type region or a junc tion formed with the first conductivity type region of the region to a reverse bias. CONSTITUTION:The manufacture is made approximately the same as conven tional devices, but P regions 4 are shaped among a base region 5 and isolation regions 4 through isolation diffusion, the lower sections of the P regions 4 are separated electrically from a substrate 1 by a buried layer 2, and the P regions 4 and an epitaxial layer 3 are connected by aluminum wirings 7. Holes entering into the P regions 4 are changed into majority carriers, but P region 4 themselves are brought to the same potential as the epitaxial layer 3 by the aluminum wirings 7, thus preventing the generation of injection to the epitaxial layer 3 from the P regions 4. It is more effective that junctions formed by the isolation diffusion regions 4 and the epitaxial layer 3 are reverse-biased.

Title: Multilayer interconnection method
Inventor: EHATA TOSHIKI

Filed: 1983-02-21
Abstract: PURPOSE:To improve the yield and the reliability of an air bridge by protecting the lower layer wirings of a crossover by an insulating film, thereby eliminating a shortcircuit of upper and lower wirings and eliminating a stepwise disconnection or a restriction in the stage of works. CONSTITUTION:Upper layer wirings 22 cross lower layer wirings 21 through an insulating film 23 having a smooth section and an insulating film 24 under the film 23. The film 23 is etched by gas plasma which does not affect the influence to a substrate, wiring metal and the film 24, thereby forming an air bridge in noncontact. After lower layer wiring metal 31 is formed by normal photolithographic and lift-off methods, a nitrided silicon film 34 is formed, and a photoresist (OFPR-800) is formed on the entire substrate. A resist film 22 is allowed to remain only on the crossover of the upper and lower layer wirings for forming the air bridge by lithography. A lower insulating film pattern 34 is formed by plasma etching with CF4 gas. When it is baked at 200 deg.C for 20min, the resist is flowed to form a semispherical shape by the surface tension. Then, upper layer wirings 32 are formed. The film 33 of air bridge structure is removed by plasma etching with oxygen gas.

Filed: 1987-02-12
Abstract: PURPOSE:To improve the product quality and production efficiency by coating the surface of a work roller by the rubber material of an urethane rubber or similar thereto and making the work roller non-driven as well. CONSTITUTION:An intermediate roll 4 and backup roll 5 are arranged on the work roller 3 of a roll leveler 2 and the driving mechanism of a strip plate 1 is separately set up as well by removing the driving mechanism of the work roll 3. In this case, the work roll 3 is formed by coating the urethane rubber 6 having elasticity or the rubber material similar thereto on a core metal 7. In the case of the strip plate 1 being guided between the work rolls 3 and flattened and straightened by receiving a plastic deformation, the generation of product flaws is prevented because of the foreign matter, etc. brought onto the strip plate 1 being pressed by the rubber material on the work roll 3 surface. Due to the grinding and changing works of the roll 3 being reduced, both the product quality and production efficiency are improved.

Title: Bus transfer control system
Inventor: KURODA KENJI
IPC: G06F13/42
Filed: 1988-02-09
Abstract: PURPOSE:To realize an inexpensive and highly efficient bus transfer control system by switching a synchronizing clock for transmission of a bus request of a bus master to a system clock or a division clock in accordance with a bus slave of the transmitting destination. CONSTITUTION:A clock switching means 14 switches a synchronizing clock for transmission of signals to a bus request transmission means 5 and an address data transmission means 6 to a system clock or a division clock in accordance with the bus request transmitting destination slaves 4a and 4b. Then a bus request is transmitted to the slave 4b requiring no high-speed process synchronously with the division clock. Thus a busy signal is received in response to the preceding bus request before transmission of the next bus request. Therefore the continuous bus requests are not transmitted and a buffer of a single stage suffices. In such a way, an inexpensive bus transfer control system is obtained.
