IPC: G01S7/12
Filed: 1985-02-07
Abstract: PURPOSE:To enable safe control of an airplane with the determination of difference in the altitude when it approaches, by coding a video depending on altitude information on a responding airplane to display. CONSTITUTION:A P/S control section 105 generates a load signal 19 depending on the presence of an altitude data 16 on take in a coded video 20 into a P/S converter section 107. A display distance signal 17 is inputted and a serial clock 22 with a varying cycle is outputted to the P/S converter section 107 so that the display video range will be constant free from the selection of display distance with a radar display 110. At the P/S converter section 107, the coded video 20 of parallel bits is converted into an altitude display video 23 to be outputted to an OR circuit 109, which ORs a shaped decoded video 18 with an altitude display video 23 and sends a secondary radar video 24 to a radar display unit 110 to be display on a PPI scope. This enables safe control of an airplane with the determination of difference in the altitude when it approaches.

Title: Measurement of thermal history
Inventor: KASHIWAZAKI SHIGERU
IPC: G01R33/60
Filed: 1990-01-31
Abstract: PURPOSE:To enable measurement of thermal history under an environment of radiation by setting a resin molded element containing an alanine crystal powder under the environment of radiation for a fixed period and comparing the intensities of an electronic spin resonance signal of the molded element before and after the setting thereof. CONSTITUTION:When a resin molded element containing an alanine crystal powder is irradiated by a specified amount with radiation, a free radical is formed in the element. The resin molded element is placed into a radiation shielding container, such as a lead container and set at a specified location under an environment of radiation. Then, after a desired time passes, the resin molded element is removed. Here, the free radical in the resin molded element attenuates according to a thermal history suffered by this element. Finally a value of the free radical before the setting is compared with that after the removal thereof to allow the learning of an actual thermal hysteresis. A free radical value in the element can be measured by using an electron spin resonator (ESR). The alanine crystal powder resin herein selected is a type that will not be melted at an expected temperature.

Said permanent magnet 3 is made rotatable around a shaft 4. Moving iron pieces 5, 6 are installed on a board 9 below the iron piece 1 so that one end of each iron piece is fastened and the other end can move up and down by hinges 7, 8, and their tips are bent upward. When the permanent magnet 3 is turned to direct the magnetic pole N from the recess 1b of said iron piece 1 to the direction perpendicular to said recess, the iron pieces 5, 6 are attracted to the iron piece 1. When the permanent magnet 3 is returned to its place, the iron pieces 5, 6 also lower to their place. In this manner, a large impact force can be generated by a small turning force.

IPC: H02K1/27
Filed: 1994-01-25
Abstract: PURPOSE:To facilitate the manufacture of a reverse-salient-pole motor by forming notches penetrating in the axial direction between poles of a ring-shaped iron core, which is laminated on the outside circumference of a reverse-salient-pole cylindrical permanent magnet whose magnetic poles are radially magnetized alternately in N and S, and which is integrated into one piece, when forming a rotor that is to be placed on the inside circumference of a stator, coaxially therewith. CONSTITUTION:The outside circumference of a rotor inner iron core 2a is magnetized in the radial direction alternately in N and S from one magnetic pole to another, to from a cylindrical permanent magnet 3. A rotor outer iron core 4 is bonded to the outside circumference of the permanent magnet 3 with adhesive. The rotor outer iron core 4 is obtained by laminating ring-shaped iron cores and integrating them into one. A plurality of grooves 7 are formed in the portions 4a between the poles of the outer iron core; the grooves 7 penetrate through the outer iron core in the axial direction, and cut in the radial direction alternately from outside and inside. The grooves 7 are filled with resin to ensure the strength. A stator 1 is obtained by winding a wire around a stator iron core 1a at a specified interval of slots 5 therein. The rotor 2 is placed inside the stator 1. This increases the magnetic resistance of the rotor, and makes it possible to simply manufacture a reverse-salient-pole motor with an increased quadrature-axis reactance.

Filed: 1986-02-07
Abstract: PURPOSE:To improve the noise immunity by using a band pass filter so as to detect a frequency component corresponding to a received pulse signal thereby controlling the validity invalidity of an automatic gain control circuit. CONSTITUTION:The band pass filter BPF and a voltage comparison circuit VC identify whether or not a desired pulse signal is received, and in case a pulse signal is received, a high level output signal is formed to control an AND gate G. The AND gate circuit G consists of two AND gate circuits to send a 2-bit signal of a level detection circuit LVD actually respectively and in case a desired pulse signal is not received, an output signal of the voltage comparison circuit VC goes to a low level to close the AND gate G. Thus, even if a comparatively large noise comes, the same signal as that at non-signal state is fed to a control circuit CONT to prevent the circuit CONT from being started.
