Title: Vector control system for induction machine
Inventor: YAMAMOTO YASUHIRO
IPC: H02P21/18
Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To represent the elements of a state equation with the constants of a T-I equivalent circuit by constituting the same dimensional magnetic flux observer of formulas of a continuous system. SOLUTION: To displace each coefficient of a state equation by a T-I equivalent circuit, a conversion formula between a T equivalent circuit constant and a T-I equivalent circuit constant is substituted into the state equation. Next, the feedback term of an observer is changed so as to be represented by induction machine constants. Consequently, separation of a primary leakage inductance and a secondary leakage inductance becomes unnecessary, and a vector controller using constants measured from a real machine as they are can be constituted. This is one wherein the elements of a former state equation have been changed to the T-I equivalent circuit constants, and the same dimensional magnetic field observer wherein a change to the T-I equivalent circuit constants has been performed is obtained.  The same dimensional magnetic field observer for vector control of an induction machine is constituted using the T-I equivalent circuit constants, and furthermore, a secondary variable is changed into a value corresponding to the exciting current of the vector control. Furthermore, rotatory coordinate transformation of a secondary circuit section is performed.

Title: Apparatus for diagnosing failure of thermistor
Inventor: YOKOI MASAAKI
IPC: G01K7/24
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To provide a thermistor failure-diagnosing apparatus which can detect not only a shortcircuited state and an opened state, but an abnormality of a thermistor when the thermistor shows a constant resistance value at all times regardless of a temperature change. SOLUTION: The failure-diagnosing apparatus supplies a current to a thermistor 2 for a longer time than a normal temperature-sampling time, thereby letting the thermistor 2 generate heat by itself. Whether a resistance of the thermistor 2 changes or not during the heat generation time is detected by detecting a voltage VA/ D. Since it can be detected whether or not the resistance of the thermistor 2 changes, an abnormality of the thermistor when the thermistor shows a constant resistance value at all times is detected.

IPC: H01R4/24
Filed: 1980-01-21
Abstract: An electrical connector for use in establishing electrical connections to the conductors of a flat cable comprises a first housing member carrying a plurality of terminals each having arms having opposed edges defining a conductor-receiving slot and having pointed extremities for piercing the insulating material of the cable, and a second housing member having a plurality of holes to receive the arms of a respective one of the terminals. The arms of the conductor-receiving portion of each terminal are formed adjacent their free ends with outwardly directed projections which are an interference fit in the associated hole in the second housing member, each arm of each terminal in use engaging the second housing member not only at the projection on the arm but also at a second position adjacent the engagement between the arm and a conductor of the cable received in the slot partially defined by the arm. The second position of engagement between each arm of each terminal and the second housing member serves to relieve the stresses induced in the arms by the engagement between the projections on the arms and the second housing member, this enhancing the contact between the arms and the conductors and ensuring reliable electrical connections.

Inventor: KATAOKA KATSUYUKI
IPC: C02F1/72
Filed: 1983-01-19
Abstract: PURPOSE:To efficiently treat COD and stenchy gas, by adding an iron salt and hydrogen peroxide to COD-contg. waste water, reacting them with said waste water to oxidatively decompose COD components, and then bringing said waste water into gas-liquid contact with stenchy gas. CONSTITUTION:An iron salt 2 such as ferrous sulfate and hydrogen peroxide 3 are added to COD-contg. waste water such as the biotreated water of night soil. Thereafter, the mixture is agitated under the condition of a pH of 3-4 and introduced into a gas-liquid contact column 4 to bring it into gas-liquid contact with stenchy gas 5. The liquid 6 after being treated is recirculated to the gas- liquid contact column 4 by a circulating pump 7. In this step, COD components in the waste water 1 are chemically oxidized and decomposed by Fenton's reaction. On the other hand, odorous components, e.g. NH3 and mercaptan, in the stenchy gas 5 are easily oxidatively decomposed by H2O2 and OH radical, and deodorized gas 8 is discharged.

Title: Bobbin rotation detector, residual thread remover and bobbin thread feeder
Inventor: MATSUYAMA TAKESHI
IPC: D05B59/04
Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To keep track correctly of residual bobbin thread and cope with the residual thread even if bobbin thread removal ends with the bobbin thread left in the bobbin, by providing more than one detecting mean that detects a detected part of the bobbin at a different angle of rotation and with different timing. SOLUTION: Sensors 4a, 4b are attached to positions facing the flange face of a bobbin 15 that treats residual thread, and a signal waveform that is output is shaped in waveform shaping sections 41 a, 41b. A bobbin rotation/non-rotation judgment section 42 outputs an 'on' signal, when one sensor 4a inputs an 'on' signal, and switches the 'on' signal to an 'off' signal, when the other sensor 4b inputs an 'on' signal. The winding reduction arithmetic means of an arithmetic means detects the amount of the bobbin thread left in the bobbin 15 from the frequency of the bobbin 15 obtained from a frequency detecting means and computes the amount of reduction in the bobbin thread to be wound around the bobbin 15, if a residual thread removal normal end judgment means considers residual thread removal to be an abnormal end.
