Title: Frequency reuse technique for high-data- rate satellite communication system
Inventor: HARORUDO EE ROOZEN
IPC: H04B7/208
Filed: 1994-10-21
Abstract: PURPOSE: To set a route of demodulated data to be transmitted to a user terminal at a destination, to remodulate the data by multiplexing it again, to generate plural sets of polarized interleave transmission beams and to transmit the remodulated data to the terminal at the destination by one transmission beam. CONSTITUTION: Input data generated by the user terminal 11 are multiplexed by frequency division and transmitted to a satellite relay system 13. The data are demodulated, the route of the data is set, the data of a frequency domain are remodulated by communicating with a second terminal 12 by the set route and re-transmitted on the beam to transmit time-division multiplexed data to the second terminal 12 by the system 13. And high performance digital data flow is re-generated on a device 30 of a satellite to communicate with the terminal 12 so that an adverse effect of uplink interference is reduced by demodulation and remodulation stages of a signal obtained from the terminal 11. Therefore, a number of users to be supported by an effective band width and a system 10 are increased, e.g. by 12 folds by reuse of double polarized wave and spaces of transmission and reception beams.

Title: Frequency converting circuit
Inventor: NODA MASAKI
IPC: H03D7/12
Filed: 1987-10-14
Abstract: PURPOSE:To form a frequency converting circuit which is small-sized and operat ed with a small local oscillating power by providing a drain grounding type oscillation and a mixer, connecting a source as the oscillation output terminal of the oscillator and the source as the local oscillating signal input terminal of the mixer, and grounding the connecting point through a bias circuit. CONSTITUTION:Sources of an FET 1 for an oscillator and an FET 2 for a mixer are mutually connected. Thus, the circuit is operated as a differential circuit. A local oscillating signal generated by an oscillator OSC oscillates the source current of the FET 2 for the mixer energetically by a current driving. Since both the output side of the oscillator OSC and the local oscillation input side of a mixer MIX are a source terminal S, the local oscillating signal can be efficiently injected to the mixer MIX. To the source terminal S of the FET 1, an input capacity by the source terminal input of the FET 2 is connected. Thus, the fluctuation of an oscillation action point due to the change of the source capacity of the FET 1 can be made small. Consequently, the fluctuation of the oscillating frequency due to a temperature change and 8 power source voltage fluctuation can be made rare, and a stabilization can be executed.

Filed: 1988-10-13
Abstract: PURPOSE:To obtain a long-life trap by forming a surface forming portion where when condensate outflows in an outlet passage, it collides and its vicinity portion by precipitation hardened metal or an alloy having corrosion-resistance so that the inner wall surface of the outlet passage is hard to be corroded. CONSTITUTION:On the surface corresponding to a portion where when condensate staying in a condensate reservoir chamber 14 flows out of a condensate discharging valve hole 26 into an outlet passage 23, the condensate collides, a core 52 and a casting mold 51 of a trap main body where precipitation hardened powder metal 56 (one or two kinds of metals among Cr, Ni, Mn, Mo and so on) is applied are made.

Title: Basic surface adjusting device
Inventor: SAKAMOTO MITSUSHIGE
IPC: B24B29/00
Filed: 1987-10-13
Abstract: PURPOSE:To eliminate the outside scattering of the dusts formed during the grinding work by sucking all the dusts by installing a cylindrical wire brush in rotatable ways in a housing so as to project a little from a dust collecting squeezer. CONSTITUTION:When a motor 5 is revolved, attaching the edge surfaces 19-21 of a dust collecting squeezer 18 onto a polished surface, a wire brush 2 inside a housing 1 revolves at a high speed and polishes the polished surface. In this case, the wire brush 2 projects a little from the edge surface of the dust collecting squeezer 18. Therefore, independently of the magnitude of the force for pressing the machine, the old coating film and rust can be polishing removed in a prescribed thickness by the wire brush 2 in revolution. The outside scattering of the dusts formed by this polishing is prevented by the dust collecting squeezer 18 installed on the other side part of the housing 1, and all the dusts can be absorbed into a dust collector. Further, the polishing thickness of a polished surface 23 is adjusted by shifting the undersurface of the squeezer 18 by raising and lowering a front roller 24 by the operation of a pressure adjusting knob 26.

Title: Dial pulse transmission circuit
Inventor: MATSUO NOBUO
IPC: H04M1/31
Filed: 1986-10-28
Abstract: PURPOSE:To reduce the sound volume of a click sound at a receiver during the transmission of a dial pulse by making the mute terminal of a dial IC into 'H', making the transistor (TR) of a muting circuit come to ON, and grounding both the ends of a telephone set through a resistor. CONSTITUTION:In response to a key input from a key board, the dial pulse output terminal DP of the dial IC repeats a high level 'H' and a low level 'L', and the TR Q1 comes to ON and OFF. When the TR Q1 comes to ON and OFF, the TR Q2 and TR Q2 come to OFF and ON, and the dial pulse is transmitted to a trunk line through a rectifying device 20. Then, while the dial pulse is being transmitted, the mute terminal MUTE of the dial IC comes to the high level 'H  and the TRs Q3 and Q4 come to ON. Thus, because both the ends of the receiver are grounded through the resistors R7 and R10, the sound volume of the click sound heard from the receiver is reduced.

Title: Automatic focusing camera
Inventor: MAEDA HIROSUKE
IPC: G02B7/28
Filed: 1987-10-12
Abstract: PURPOSE:To eliminate a failure in releasing a shutter at right moment by computing a specific position between objects, and controlling a photographic lens to a focus position based on the arithmetic result of a bit of range measurement information that a photographer selects optionally among plural bits of range measurement information. CONSTITUTION:When objects are at distances between the nearest-side distance Dmin and the farthest-side distance Dmax, the photographic lens is only adjusted to the center value of the current exposure quantity difference and then the exposure quantity difference becomes uniform among the objects at the distances between the farthest-side and the nearest-side distances Dmax and Dmin. Thus, the center value based upon the depth alpha of field and the center value D obtained in consideration of the exposure quantity difference alpha are different even when the farthest-side and the nearest-side distances Dmax and Dmin of an object are equal and the photographer only makes the selection of which one is important. Namely, a focus adjustment can be made to a focus position in consideration of all range-measured objects or to a focus position regarding only one object that the photographer selects intentionally.
