Title: Modem and line interface device for modem
Inventor: HIYOSHI YUICHIRO
IPC: H04M11/00
Filed: 1994-11-25
Abstract: PURPOSE: To obtain a sufficient transmission power even when a low power supply voltage is applied to a terminal equipment. CONSTITUTION: A hook switch 10 is closed in the case of transmission and a transmission signal amplified by a transmission driver section 3 is sent from a point A to a telephone line. A power supply section 8 generates a prescribed voltage VE from a DC voltage of a telephone line for a power supply voltage for the transmission driver section 3. Thus, a large transmission power is obtained independently of the power supply voltage of a terminal equipment. Furthermore, the output of the transmission driver section 3 is inversely amplified by a cancellation amplifier 6 and the amplified signal is fed to one terminal of a resistor 5 to cancel part of the transmission signal fed to the other terminal of the resistor 5 via a reception section 4 from the point A.  Thus, the transmission signal is not fed to the reception section 4 but also the power consumption in the resistor for impedance matching is eliminated.

Title: Catalyst for purifying exhaust gas
Inventor: YOKOTA KOJI
IPC: B01D53/86
Filed: 1994-11-25
Abstract: PURPOSE: To provide an exhaust gas purifying catalyst capable of performing reduction purification of NOx in the exhaust gas with an improved efficiency by providing a structure in which the catalytic precious metal and an NOx occluding material can fully perform their own functions. CONSTITUTION: An exhaust gas purifying catalyst comprises a first catalytic precious metal 20 consisting of at least either platinum or rhodium and supported on a first porous carrier, a first catalyst supporting layer 2 consisting of an NOx occluding material 22 and a second catalyst supporting layer 3 consisting of second catalytic precious metals 30 and 31 supported on a second porous carrier and covered on the first catalyst supporting layer 2. When exhaust gas passes through the second catalyst supporting layer 3, since its reductive component is removed by oxidation, the hindrance to the oxidative reaction of NOx caused by the reductive component does not take place and the NOx can be efficiently occluded in the NOx occluding material 22.  Although the occluded NOx is released into a reductive environment from the NOx occluding material 22, since it is reduced on Rh of the second catalyst supporting layer high in N2 selectivity, the N2 selectivity rate is improved.

Title: Ac motor control system
Inventor: IWASHITA HEISUKE
IPC: H02P23/00
Filed: 1992-10-07
Abstract: PURPOSE:To restrict maximum current within a limit level during deceleration while increasing maximum torque during acceleration. CONSTITUTION:A torque command Tcmdl is determined(S1) and if it does not exceed a predetermined limit value Ko during acceleration, the torque command Tcmdl is outputted as a torque command(current command) Tcmd2 for current loop(S2, S3, S9, S10). If the limit value Ko is exceeded, amplitude Io of actual current is determined(S5) and then a limit value L is determined based on the limit value Ko and the magnitude R(T) of a torque command Tcmd2 obtained one period before(S6). The torque command Tcmd1 is then clamped by the limit value L thus producing the torque command Tcmd2 for current loop. Steps S4-S8 are executed at the time of deceleration. Since the limit value L is determined from the ratio between the current command and the amplitude of actual current during acceleration and the torque command Tcmd is clamped at that value, amplitude of actual current does not decrease thus increasing output torque. If the actual current increases due to counter- electromotive force during deceleration, the limit value L decreases to decrease the command thus restricting the actual current within a limit value.

Title: Electromagnetic induction heating coil
Inventor: TANAKA JIYUNKO
IPC: H05B6/12
Filed: 1987-11-19
Abstract: PURPOSE:To reduce the power consumption of a heating coil into zero so as to improve the efficiency thereof by using a superconductive wire material as the heating coil suitable for electromagnetic induction heating. CONSTITUTION:A superconductive wire material is used as a heating coil 1 suitable for electromagnetic induction heating. Thus, in the condition where the temperature, current and magnetic field of the superconductive material are all under the critical points thereof, the resistance is zero and therefore it is possible to eliminate the power consumption due to the heating coil 1. In addition, since the superconductive material has no electric resistance, the diameter or sectional area of the wire 1 can be reduced and the number of winding enlarged. Accordingly, it is possible to reduce a current value to generate a definite magnetic flux, power consumption in a coil power source and induction loss in the coil. The superconductive wire material is sealed with a heat-proofing and plastic pipe, and annealed after formed in a coil shape so that the structure of the superconductive material is prevented from occurrence of any crack and deformation.
