Title: Multilayered compact slot antenna structure and its method
Inventor: HAUB DAVID RYAN
IPC: H01Q13/10
Filed: 1998-05-06
Abstract: PROBLEM TO BE SOLVED: To provide a multilayered slot antenna, the physical length of which can be reduced significantly. SOLUTION: The physical length of a multilayered compact slot antenna 710 is shortened, forming inductor structures 790 and 795 in the slot antenna 710 by using one or more conductive layers which are separated form each other by a dielectric layer. When inductances are added to the slot antenna 710, the physical length of the slot can be shortened, without changing the radiated frequency range of the antenna. The geometric structures of the inductor structures 790 and 795 can be designed, so that the directions of a current and an electric field crossing the slot viewed with the slot at the center is maintained. When the structures are designed in such a way, the efficiency of the antenna is improved and many compact slot antennas can be constituted.  In addition, capacitor structures 780 and 785 can also be incorporated in the antenna 710, and the magnetic energy additionally accumulated in the inductor structures 790 and 795 can be balanced.

Abstract: PURPOSE:To evolve a highly-concentrated HI gas and to recover calorie effectively, by dividing an aqueous solution of MgI2 obtained by the reaction between MgO and I2 into two, adding MgO to one of them, heating the blend, absorbing evaporated substances in the other, decomposing the reaction product thermally. CONSTITUTION:In a Mg-I2 system cycle, MgO is reacted with I2 (the first step reaction) in the presence of water and excess I2. The formed Mg(IO3)2 is filtered off to give an aqueous solution of MgI2, which is divided into two. 3mol based on 1mol MgI2 of MgO is added to one of them, the prepared blend is evaporated under heating, 3Mg(OH) MgI2 is formed, generated steam and iodine  vapor are absorbed in the other aqueous solution of MgI2, and vapor calorie is  recovered. The diluted aqueous solution is returned to use it for the first step reaction, and the reaction product in a solid phase is decomposed at high temperature, to evolve a highly concentrated IH gas having a molar ratio of MgO  to H2O of 1:1.

Title: Compressor-expander circuit
Inventor: KATOU MASAAKI
IPC: G11B20/10
Filed: 1977-11-25
Abstract: PURPOSE: To improve precision by selecting a plural number of attenuators, by compressing a signal by an operational amplifier equipped with attenuators at its feedback loop, and by expanding the signal by separated attenuators.  
     CONSTITUTION: The output of sample holding circuit 11 is supplied to operational amplifier 12 and also to comparator 13. Comparator 13 has a plural number of reference levels and discriminates an input signal levels to output a control signal, thereby selecting attenuators 16a to 16c. The output of amplifier 12 is converted into PCM codes via A/D converter 14. Switches 15, 19 and 20 change over, interlocking together, to the T side at a compressing time and to the R side at an expanding time. Attenuators are therefore used in common, so that even when constituting parts of low precision are used, the precision of this circuit can be improved without improving the precision of each part.

Title: Acceleration sensor
Inventor: KONNO TETSUO
IPC: G01P15/10
Filed: 1983-08-02
Abstract: PURPOSE:To improve detection precision by providing a weight attached by a support member and an oscillation circuit for a piezoelectric vibrator, and measuring acceleration by the output frequency of the oscillation circuit. CONSTITUTION:When acceleration is ''0'', the output frequency of the oscillation circuit for the crystal resonator 3 is denoted as f0. When an acceleration sensor is attached to a body which moves in an X-axis direction with acceleration alpha, a force F=malpha operates on the weight 9 in the -X-axis direction. Consequently, the tensile strength applied to the crystal resonator 3 decreases. When an X- axial force is applied to the AT-cut crystal resonator, the resonance frequency increases up to f0+DELTAf. When the acceleration operates in the -X-axis direction, the force decreases and the resonance frequency also decreases to f0-DELTAf. Thus, the acceleration is measured as the output frequency of the oscillator using the crystal resonator 3 or variation in the output frequency. Therefore, the detection precision is improved.
