Abstract: PURPOSE:To effectively reform a hydrocarbon with steam through effective reuse of high-temp. heat of a reformed gas without use of any waste heat boiler, by effecting the steam reforming in a tubular space portion of a particular reaction tube and effecting CO conversion in an inner tube portion. CONSTITUTION:A steam reforming catalyst layer A is formed in a space portion 4 between an inner tube 1 and an outer tube 2 which cooperate with each other to form a double-tube structure and communicate with each other through a partitioning plate 3 which has a number of fine pores for transmission and which is provided at the opening portion located at the bottom of the inner tube 1, while a CO conversion catalyst layer B is formed in an inner space 5 of the inner tube 1, thereby forming a reaction tube 20. For example, three reaction tubes are provided within a heating oven of a steam reforming device. A raw material comprising a mixed gas comprised of a hydrocarbon and steam and having a temp. of 300-400 deg.C is fed through a conduit 21. The mixed gas comes down from the direction of an arrow 10 of each reaction tube through the catalyst layer A. At this time, the mixed gas is heat- exchanged with the heat of gas rising through the catalyst layer B and heat from the outer surface 2, thereby causing the mixed gas to be heated at about 800 deg.C. This is turn causes the mixed gas to be converted into a gas contg. H2, CO and CO2. The gas rises through the catalyst layer B to bring about a CO conversion reaction. The gas thus formed is led to the direction of an arrow 11 and discharged from a discharging port 23 through a gas collecting tube 22, to transfer it to the next step.

Filed: 1989-06-27
Abstract: PURPOSE:To reduce the switching loss by alternating the high frequency operating period when switching elements are mutually turned on/off to supply the high frequency power to a load and the direct current operating period when one of the switching elements is turned on/off to supply the direct current power to the load at the time of no-load in a load circuit. CONSTITUTION:A load circuit in which capacitors C3, C4 are connected to a load H in parallel and an inductor L1 is connected to the load H in series is comprised. At the time of no-load in this load circuit, the high frequency operating period when a first and a second switching elements Q1, Q2 are mutually turned on/off to supply the high frequency power to the load H and the direct current operating period when one of the first and the second switching elements Q1, Q2 is turned on/off to supply the direct current power to the load H are alternated in a cycle lower than the on/off cycle of the switching elements Q1, Q2. Consequently, In the case that the load H is not started in the high frequency operating period, the direct current operating period following to the high frequency operating period becomes the dormant period practically after conclusion of charge of a capacitor connected to the load H in parallel. The reactive current flowing to the switching elements Q1, Q2 at the time of start is thereby reduced to reduce the switching loss.

Title: Contact type temperature detector
Inventor: YAMAJI KATSUHIKO
IPC: G01K11/04
Filed: 1986-07-16
Abstract: PURPOSE:To accurately detect the temperature of a temperature detecting portion without being affected by an environmental condition by making a temperature detector an expandable container which is connected with a thermosensible cylinder containing a metal hydride via a thin pipe and whose volume changes in accordance with the hydrogen equilibrium pressure of the metal hydride. CONSTITUTION:A metal hydride 13 is filled in a thermosensible cylinder 12 provided in contact with a temperature detecting portion 11. A container 14 that is expandable and shrinkable in accordance with an internal pressure is connected with the thermosensible cylinder 12 via a thin pipe 15. The metal hydride 13 has a prescribed hydrogen equilibrium pressure at a prescribed temperature. When the metal hydride is cooled, the hydrogen equilibrium pressure is reduced to occlude hydrogen and, when heated, the metal hydride discharges hydrogen. Accordingly, when the temperature of the thermosensible cylinder 12 rises, the volume of the expandable and shrinkable container 14 is increased to expand and elongate the container 14 and, on the other hand, when the temperature of the thermosensible cylinder 12 falls, the container 14 shrinks. Thus, the hydrogen equilibrium pressure of the metal hydride changes in accordance with the temperature of thermosensible cylinder 12 and, in accordance therewith, the expandable and shrinkable container 14 expands or shrinks to enable the temperature to be detected, for example, by the opening or the closure of contacts 17 and 18.

Title: Frequency deciding method
Inventor: ATSUTA HIROMI
IPC: H04L27/14
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To accurately and speedily decide even a low sampling frequency when an FSK signal is converted from analog to digital and transmitted through a time-division time slot. SOLUTION: When a calculation period is judged from a peak level calculation period criterion, a peak level (Dp) is calculated and held in a storage means 1. When a linear PCM hold number is, for example, <=2576, peak level calculation is not performed and data input is expected. Then expected values at, for example, 1300 and 2100 Hz are calculated from linear PCM (Dn-1) right before the currently held level and stored in the storage means 1. The Dn-1 frequency decision result is fetched out of the storage means 1; and it is decided that the Dn frequency decision result is 1300 Hz when Dn is still in a prediction range of 1300 Hz, otherwise, 2100 Hz when in a prediction range of 2100 Hz, or it is decided that the last decision is held (1300 Hz) in neither case of the above.

Inventor: WATANABE YUKIHARU
IPC: H04J1/00
Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To obtain a small-sized, simple, and inexpensive device by multiplying a wave to be modulated by a function and additionally transmitting a subcarrier including coefficient information on the function, restoring the function on a reception side, limiting the generation of higher harmonics due to a cosine wave component of the subcarrier subordinately, restoring the peak value by multiplying the receive wave by the reciprocal of the function in modulation, and reducing transmission errors. SOLUTION: For a signal inputted to an input terminal 1, a modulation part 2 imposes digital modulation on multiple subcarriers to obtain a modulated wave f(m). In this case, an amplitude compression part 3 sets a reference value of the amplitude of the modulated wave f(m) to obtain an output f(m)*f(g) which is proportional to the square root f(g) of the modulated wave f(m). Two symbol sections 2t are regarded as one cycle and a subcarrier f(t/2) which is orthogonal to the modulated wave f(m) is further generated and transmitted additionally to the output f(m)*f(g). Namely, f(m)*f(g)+f(t/2) is transmitted. On a reception side, the subcarrier is regenerated by an amplitude expansion part 7 through a power amplification part 6.

Inventor: TAKEDA TAKEHIRO
IPC: H01J49/42
Filed: 1983-09-10
Abstract: PURPOSE:To enable ions of low mass ranges to be analyzed without using any complicate circuits by placing an electromagnet in the back of a tetrode electrode and separating ions of low mass ranges according to mass by performing field scanning of said electromagnet. CONSTITUTION:In detecting ions of low mass ranges such as hydrogen ion and helium ion, a given electric field permitting all ions to pass is applied to a tetrode electrode 4 by means of a controlling part 8. The voltage applied to the deflection electrode 6 is also controlled by the controlling part 8 in such a manner as to deflect ions toward an electromagnet 10. As a result, ions focused by an ion-focusing electrode 3b after being led out from an ion source 2 by means of an ion-leading-out electrode 3a, pass through the tetrode electrode 4 before being introduced toward the electromagnet 10 by means of the deflecting electrode 6. Ions passing through an incidence slit 12, enter the electromagnet 10. At this point, the current of the electromagnet 10 is controlled by the controlling part 8 to achieve field scanning thereby causing ions of low mass ranges to be separated according to mass. Separated ions, after passing through a collector slit 14, are detected with a low mass range detector.
