Title: Production of fe-cr-co permanent magnet
Inventor: TAWARA KAZUNORI
IPC: B22F3/04
Filed: 1983-04-26
Abstract: PURPOSE:To adjust easily raw material powder and to enable production of a long-sized product in a method for producing an Fe-Cr-Co permanent magnet by a powder metallurgical technique by using hydrostatic press forming in molding raw material powder. CONSTITUTION:Alloy powder 9 consisting, by weight, of 17-45% Cr, 5-30% Co and the balance Fe is prepd. A molding device consisting of a mandrel 5 fixed to the center in a pressure vessel 1 formed by fitting respectively a top cover 3 and a bottom cover 4 to the top and bottom of a cylindrical part 2 and a molding cylinder 6 formed of an elastic material such as rubber provided on the outside of said mandrel is used in the case of obtaining, for example, a long- sized cylindrical magnet. The molding is accomplished by removing the cover 3, packing the powder 9 into the cylinder 6, mounting the cover 3, and feeding working oil 7 to the outside of the cylinder 6 then closing hermetically and clamping the vessel 1. The working oil is fed through the feed port 8 mounted to the cover 3 and the powder is molded under pressure. The resulting molding is subjected to a heat treatment after sintering so as to be made into a permanent magnet.

Title: Helical antenna
Inventor: TERADA NORIYOSHI
IPC: H01Q11/08
Filed: 1990-03-26
Abstract: PURPOSE:To simplify a power feeding circuit by composing one conductor wire, in a pair of conductor wires, of a coaxial wire, symmetrically constructing the other conductor wire as the coaxial wire, and connecting the both conductors at the end of helical winding. CONSTITUTION:The conductor wire 5 is constructed symmetrically to the coaxial wire 6. For a high frequency current to be supplied from the coaxial wire 6, the current of a central conductor flows to the conductor 5 as it is at a power feeding point while maintaining the equal size of the current flowing on the inside of an external conductor, and the current in the reverse direction flows on the outside of the coaxial wire 6. At such a time, when connecting the both conductors at the end of helical winding, the high frequency current flows only in a required radiation part. When impedance matching at the power feeding point 4 is not made sufficient by the number of helical winding and pitches or the like, the impedance is matched by loading a suitable impedance element 7 onto the both conductors. Thus, a balanced/unbalanced conversion circuit is not required for a circularly polarized helical antenna and a simple power feeding system can be realized.

Title: Car mounting data receiver discriminating running direction
Inventor: MARUOKA MASATO
IPC: G01S1/68
Filed: 1993-03-31
Abstract: PURPOSE:To reduce the possibility of the erroneous detection of a running direction by prohibiting the discrimination of the running direction when a frame synchronous signal is not detected even if the intensity of received wave is judged to be a level being distinguishable in the running direction of a vehicle. CONSTITUTION:A phase detecting section 34 extracts an amplitude signal at a periodic position decided on the basis of the end of a frame synchronous signal issued from a pulse generating circuit 27, and the amplitude signal lying upon the synchronous signal is discriminate for discriminating the running direction of a vehicle. In this case, only when a beacon signal intensity detecting circuit 26 discriminates that the strength of a beacon signal wave is sufficient for discriminating the running direction of the vehicle, and a pulse generating circuit 27 detects the frame synchronous signal, the discriminating action of the running direction in the detecting section 34 is carried out. Thus the phase of the amplitude signal is investigated on the stage being far away from a data frame where the synchronous signal is detected for discriminating the running direction as a result, and the discriminated accuracy elated to the phase of the amplitude signal to the detected synchronous signal is improved for reducing the possibility of erroneous detection.

Title: Signal processing circuit and gain adjustment method
Inventor: NAGAI TOMOKAZU
IPC: H04B1/40
Filed: 1995-03-30
Abstract: PURPOSE: To reduce the production cost and to attain the highly accurate and two-way signal transmission gains for an A/D hybrid semiconductor integrated circuit which contains the A/D and D/A converters and performs two-way signal processing. CONSTITUTION: A return switch 116 is placed between the input of a sending amplifier 103 and the output of a receiving amplifier 114. A variable voltage source 117 is connected to the input of the amplifier 103 via a switch 120. Then a sending correction part 106 and a receiving correction part 111 are provided among the output of an A/D converter 105, the input of a D/A converter 112 and a signal processing part 107 respectively. These component parts are all controlled by an adjustment/control part 118, so that both sending and receiving gains are adjusted. As the gains are automatically adjusted while an LSI is operating, the gain trimming time is shortened and the number of trimming circuits is decreased for production of the LSI. Thus the LSI production cost can be reduced. Furthermore, the gain variance due to the temperature change caused in an LSI chip can be corrected by the highly accurate adjustment and then the gain stability is improved.
