Title: Device for discharging passing steam and condensed water in which flow speed is acoustic velocity
Inventor: NAKANO IWAO
IPC: F01D25/32
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To recover passing steam at a flow speed close to acoustic velocity so as to provide low temperature steam having good thermal efficiency by directly absorbing passing steam and condensed water passed through a jacket to the outside of a cam in a jet ejector condenser and keeping the flow speed of vacuum steam close to acoustic velocity. SOLUTION: A jet ejector condenser 17, an ejector pump 23 and a hot well 21 are provided. Vacuum steam and condensed water having a flow speed close to acoustic velocity are received through incursion steam pipes 7 and 8, a jacket, passing steam pipes 13 and 14 and the jet ejector condenser 17 to the hot well 21 without using any traps. Since the ejector pump 23 has a head of over 60m, the jet ejector condenser 17 has a high vacuum attraction force. Thus, a temperature zone of 20 to 60 deg. is controlled by steam instead of hot water and the device is very effective in terms of energy utilization.

Filed: 1992-12-21
Abstract: PURPOSE:To increase purity of 1,4-cyclohexanedicarboxylic acid obtained through hydrogenation of terephthalic acid by using a reactor lined with a highly acid resistant or acid resistant material to prevent decreasing of a catalyst activity and subjecting to contact the product with steam. CONSTITUTION:A highly acid resistant vessel or a vessel lined with an acid resistant material is used as a reactor and a solution containing terephthalic acid is hydrogenated in the presence of a palladium catalyst(the first step). Then, the obtained solution containing 1,4-cyclohexanedicarboxylic acid is subjected to contact with steam and impure materials are removed by taking out to the steam side(the second process). 1,4-Cyclohexanedicarboxylic acid(1,4- CHDA) is obtained in this way. The hydrogenation can be carried out at >=2 to <=10Kg/cm<2> hydrogen pressure. It is preferable to use a vessel lined with glassy material as the reaction vessel. It is preferable to subject a solution containing 1,4-CHDA to countercurrently contact with steam and absorb the steam containing impurities in the alkaline solution, then reuse the steam.

Title: In-phase quadrature phase coupler
Inventor: YOSUN UU
IPC: H04B5/00
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To ensure the appropriateness of an RFID (radio frequency identification) system by using a phase shifter which causes a 90-degree phase shift out of one of modulator output signals in regard to the 2nd frequency and an adder which adds another modulator output signal to a phase-shifted output signal in terms of vector. SOLUTION: An in-phase/quadrature phase coupler of an RFID system utilizes a modulation rear dispersion technique with which a modulated subcarrier undergoes the rear dispersion modulation for a CW carrier signal. Then the phase coupler connects together the quadrature and in-phase outputs of an quadrature demodulator in terms of non-destruction. The I and Q outputs of the quadrature demodulator are orthogonal to each other in relation to the carrier frequency. The I output is applied to the input side of a phase shifter 200 and causes a 90-degree phase shift to the I mixer output in relation to the subcarrier frequency. The output of the shifter 200 is connected to the input side of an adder 202. The output of the adder 202 is equal to the vector sum of the Q output and the phase-shifted I output.

Title: Non-volatile semiconductor storage
Inventor: ARITOME SEIICHI
IPC: G11C16/06
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To prevent a wiring error when a voltage being applied to a bit line and a selection gate line lowers on an STI is used. SOLUTION: First, a voltage, for example, 3 V is applied to a Vbit 2, a voltage, for example, 5 V is applied to Vsg1, and a voltage Vdif is transferred to the diffusion layer of a memory cell. In this case, Vcg1-Vcg4 are simultaneously set to 5 V or the line, and all diffusion layers of the memory cell and a channel part are set to Vdif. Before the voltages Vcg1-Vcg4 of word lines WL1-WL4 are increased to 10 V or 20 V, the voltage Vsg1 of a selection gate line SG1 is decreased to 2 V, thus preventing the charge of Vdif from passing through the bit line via a selection transistor QS1 and hence preventing potential from being decreased.
