Title: Phased array antenna
Inventor: HIRATA TOSHIKIYO
IPC: H01P5/12
Filed: 1988-05-18
Abstract: PURPOSE:To realize a microstrip antenna with a small area by laminating an array antenna board and a drive circuit board with a phase shifter and a distribution/coupling device or the like mounted thereupon. CONSTITUTION:When a high frequency signal is supplied via coaxial connectors 7, 10, the signal is distributed to each variable phase shifter 8 by a distribution/ coupling device 9, a controller 11 controls the phase shift angle of each variable phase shifter 8 based on a direction designation data inputted via connectors 8, 12 to shift the phase of the high frequency signal supplied to each exciting element 16. Thus, a radio wave is emitted in a direction designated by the direction designation data. Furthermore, when the element 16 receives a radio wave to generate a high frequency signal, it is shifted in the designated order by the phase shifter 8, supplied to the distribution/coupling device 9, where it is synthesized and a high frequency signal is outputted externally via coaxial connectors 10, 7. Since the drive circuit board 4, the exciting element base 5 and a resistive element board 6 are laminated in this way, the area of the entire antenna is reduced.

Title: All-band double heterodyne am receiver
Inventor: TAKEDA TADASHI
IPC: H04B1/26
Filed: 1983-07-05
Abstract: PURPOSE:To obtain a good receiving characteristic with a simple circuit constitution by setting the first intermediate frequency on the outside of upper band of a receiving band and connecting a tuning circuit having a series resonance and a parallel resonance closely to the output, and setting the frequency of an image signal at a minimum output point of the series resonance point. CONSTITUTION:The transmission characteristic appearing across both ends of a capacitor 19 is an output characteristic shown in a figure, and a maximum output point due to the parallel resonance characteristic and a minimum output point due to the series resonance characteristic are obtained. In this case, values of a coil 16 and capacitors 17, 18, and 19 are so selected properly that the maximum output point has the first intermediate frequency and the minimum output point has the image frequency generated by the second local oscillating circuit. By this constitution, an ANT input circuit secures sufficient image characteristic, degree of amplification, and degree of selection even with an LPF, and further, the local oscillation can be covered with a single variable capacitor to make a band changeover switch unnecessary.

Filed: 1987-05-20
Abstract: PURPOSE:To easily and accurately attain an inter-gap length and a head height difference of a double-azimuth magnetic head by joining positive and negative azimuth core blocks with a nonmagnetic body between them. CONSTITUTION:A second core block half body 14 and a first core block half body 10 are fitted to each other with a track abutting groove 9 between them so that a magnetic body slope 9a of the groove 9 and a gap holding film 13 formed on the second core block half body 14 face each other and are brought into contact with each other, and a nonmagnetic joint member 15 is inserted to a glass filling groove 12 and a winding groove 11 and is fused and joined. A nonmagnetic body 2 whose both faces a low-melting point glass 20 is stuck is held between a positive azimuth core block 17 and a negative azimuth core block 19, and this glass is fused to join both core blocks 17 and 19. At this time, an inter-gap length l and a head height difference DELTAH are adjusted to regular values. Thus, the double-azimuth magnetic head where dimensions and the quantity of the inter-gap length and the head height difference are stable is obtained with a good yield.

Title: Cutter
Inventor: EMURA SHIGEO
IPC: B27B9/00
Filed: 1978-10-03
Abstract: PURPOSE: To straight cut hard materials, such as, concrete materials, etc. without using a cutting guide when cutting the materials by means of a circular saw system cutter.  
     CONSTITUTION: In this cutter that a motor 9 is mounted to an upper surface of a base 1 and a rotary edge 3 is installed to the motor 9 and exposed to a lower surface of the base 1, handle 5 is disposed to a rear end of the upper surface of the base 1 in a shape that is connected to a cover 2, and a split edge 6 is mounted to the lower surface of the base 1 located at a lower portion of the handle 5 so that the edge be positioned on the same straight line as the rotary edge 3. Consequently, when the base 1 is slid on an upper surface of a body to be cut and cutting is advanced, a rear portion of the base 1 does not shake laterally in the cutting direction even if concentrating upon the strong push of the handle 5 because the split edge 6 enters a cut groove formed by means of the rotary edge 3, thus the cutter accurately goes straight toward the cutting direction of the rotary edge 3.

Title: Constant rate feeder for powder
Inventor: KIMURA TAKEHIRO
IPC: B65G53/24
Filed: 1988-05-17
Abstract: PURPOSE:To feed powder continuously and accurately to a target position by employing a control device for controlling the displacement speed of a nozzle. CONSTITUTION:When an appropriate amount of carrier gas is fed through a tube 48 to a nozzle 4 and blown out of a nozzle outlet 42a on the fore-end surface 43 of the nozzle to powder 2, powder near the fore-end surface 43 is disturbed and a small mixed phase space d containing uniformly mixed carrier gas and powder is produced. Because the inside space of a container 31 is airtightly separated from the outside except for the nozzle outlet 42a and a powder outlet 41a, the mixed phase produced flows out of a fore-end of a feed tube 47 opened to a target position. If the feed of the carrier gas is continued, the small space d grows gradually until the energy of the carrier gas jet does not reach the surrounding wall of the space d and the flow of the powder 2 stops. Thus, the powder 2 can continuously flow out if the nozzle 4 is moved at a constant speed in the direction of the bottom of the container 31.
