Title: Power distributer/synthesizer
Inventor: KOBAYAKAWA SHIYUUJI
IPC: H01P5/12
Filed: 1987-05-29
Abstract: PURPOSE:To obtain a radial type power distributer/synthesizer with no reflecting wave in existence while propagation loss is reduced by arranging closely square waveguides radially to upper or lower faces of an opposite face and penetrating an H-face slit with a prescribed size to the mutually close contact face. CONSTITUTION:Eight square waveguides 2 are adhered closely to one face of a hollow short cylinder 6, arranged radially around the center shaft and each close contact face is provided with an H-face slit 7 with a prescribed size while it is penetrated through a prescribed location. In the case of a distributer, a coaxial line 3 is used as an input port, and an input wave propagated in the TEM mode is converted into the radial mode by the mode converter 4 at the tip and propagated in the inside of the short cylinder 6 while the wave is being spread in a radial direction with respect to the center axis. Then the wave is coupled with the waveguide 2 adhered, closely by the H-face slit 7 and the radial mode is converted into the TE10 mode and vice versa, and the output is distributed to each waveguide 2 and extracted. The electric field is concentrated by providing the slits a half wavelength in depth between the adjacent slits 7 radially.

Title: Detecting method of training start point of modem
Inventor: KAKO TAKASHI
IPC: H04L27/227
Filed: 1984-07-02
Abstract: PURPOSE:To detect accurately the start point of training even when a circuit is in a noisy state by detecting the start point of a training signal from the relative level of the sum of a level output obtained from a received signal and the correlation output of the received signal on a time axis. CONSTITUTION:The received signal as is waveform-shaped by a roll-off filter, whose output is inputted to an absolute value part 2 and a mutual correlation detection part 8. The absolute value part 2 calculates absolute values of X and Y of the output of the roll-off filter 1 and averages them to generate an energy level output Ra. A mutual correlation detection part 8, on the other hand, calculates the correlation between two symbols and outputs three correlation outpus, Va, Vb, and Cc for one symbol. When the output of the roll-off filter 1 is the training signal, the two symbols are put in phase with each other through the phase rotation of ejtheta, so that the mutual correlation output is maximum. When the output is a noise, etc., having no correlation, they are not in phase by the phase rotation of ejtheta, so the mutual correlation output is small (almost zero).

Abstract: PURPOSE:To adsorb away and recover stably an org. solvent from gas even if the concn. of the org. solvent fluctuates with the lapse of time by treating the gas contg. the org. solvent with a fixed bed type absorption device and a multistage fluidized bed type adsorption device. CONSTITUTION:The gas 9 contg. an org. solvent such as freon produced from a dry cleaning device 15 is sucked with a fan 7 and is supplied to a fixed bed type adsorption device 2. The activated carbon as an adsorbent is packed therein, and when the gas contg. the org. solvent in a high concn. is conducted to the device, the activated carbon adsorbs the solvent and when the concn. is decreased, the activated carbon desorbs the adsorbed org. solvent. The gas having always a uniform and specified concn. is discharged from the device 2 and is conducted to the next multistage fluidized bed type adsorption device 1, where the org. solvent contained in the gas is adsorbed away by activated carbon. The activated carbon in the device 1 forms a circulating bed for the adsorbent. The activated carbon 10 on which the org. solvent is thoroughly adsorbed is conducted to a regenerator 4 where the carbon is subjected to heating and desorbing. The regenerated carbon circulates in the device 1. The desorbed org. solvent is recovered for reutilization in the dry cleaning.

Title: Method and device for measuring flow rate or flow speed of liquid
Inventor: BURENDAN MAAKU EDOWAADO KUIN
IPC: G01F1/66
Filed: 1994-06-20
Abstract: PURPOSE: To measure the flowing speed or the flow rate of a fluid flowing in a smooth hollow pipe by transmitting sound waves with the same frequency diagonally to the flow direction of the fluid, making the sound waves as continuous alternating waves transversely cross the flow of the fluid in the transmission direction or the reversed direction, passing the flow of the fluid, and adjusting the communication frequency. CONSTITUTION: Sound waves having the same frequency are at angle α to the flow direction of a fluid, that is the center line 2 of the pipe 1a, and produce continuous waves alternating in one direction and in the reverse direction and the waves are so transmitted as to transversely pass the flow of the fluid shown as an arrow F after passing through converters 4a, 4b. Of one direction and the reverse direction, the phase relation of the transmitted and received, acoustic signals in one direction is practically made to be the minimum by adjusting the transmission frequency and preferably lowered to be zero.  On the other hand, of one direction and the reverse direction, the phase relation of the transmitted and received acoustic signals in the reverse direction is measured, the magnitude of the adjustment of the transmission frequency is united with the measured phase relation in the reverse direction in an algeraic manner, and in this way the flow rate or flowing speed of a flowing fluid can be computed.

Title: Vibration type gyro scope
Inventor: SATO AKIRA
IPC: G01C19/56
Filed: 1995-06-05
Abstract: PURPOSE: To prevent a null voltage generated in a piezoelectric detection section in the driving of a vibrator from overlapping a detection output of Coriolis force as a noise. CONSTITUTION: Vibrators 10a, 10b, 10c are formed on an elastic body 10 in which piezoelectric material 12 is laminated on an elastic plate 11. When electric power is applied to electrodes 13, the vibrators 10b, 10c on both sides and the vibrator 10a in the central section are vibrated inversely to each other in X direction. Each of vibrators are vibrated in Z direction by the Coriolis force. The amplitude directions of the vibrators 10b, 10c on both sides and one 10a in the central section are reversed to each other. Polarization directions at a piezoelectric detection section are the same, then when the vibrators are deformed in the same directions, outputs having the same polarization are obtained.  While null voltages are generated on detection electrodes 14a-14c by the distortion of the piezoelectric material 12 at a time when the vibrators are driven in the X direction, it is possible to cancel the null voltage by subtracting a detection output of the central vibrator 10a from the sum of detection outputs of vibrators 10b, 10c on both sides.
