Title: Sound signal amplifier circuit
Inventor: TAKEUCHI MASARU
IPC: H03F3/68
Filed: 1987-04-30
Abstract: PURPOSE:To prevent the occurrence of noise and crosstalk by providing a buffer amplifier supplying a reference potential to a power amplifier and a load with a low impedance and a current drive circuit converting an output signal of a preamplifier into a current form signal and supplying it to the power amplifier. CONSTITUTION:A signal of current form outputted respectively from current drive circuits 17A, 17B is fed respectively to an inverting input of power amplifiers 18A, 18B. One terminal of speakers 19A, 19B is connected respectively to each output of the buffer amplifiers 18A, 18B and the other terminal is connected to the output terminal of the buffer amplifier 13 of a low output impedance. Although the buffer amplifier 13 offers a low impedance, because the speakers 19A, 19B are large loads, the potential at the output terminal of the buffer amplifier 13 is fluctuated more or less. However, the potential fluctuation is shut off by the buffer amplifier 13 and the potential at a connecting point 11 is not fluctuated and occurrence of noise is prevented to the preamplifiers 15A, 15B.

Title: Reply system for multiple address communication
Inventor: KOYAMA NOBUHIRO
IPC: H04J1/08
Filed: 1985-05-22
Abstract: PURPOSE:To simplify the return control of reply by dividing an occupied band used at multiple address communication into a required number and assigning the divisions exclusively to a reception station. CONSTITUTION:A transmission multiple a address data sent from an earth station 7 is modulated by a modulator 11 and amplified by an amplifier 12 and subjected to limit at a prescribed band by a band pass filter 13 and the result is sent from an antenna 3 through a switch 99. In the operation of reply data, the occupied band of a radio wave used for the transmission of a multiple address data is divided into the number of earth stations or over being an object of multiple address communication and each occupied band is assigned for the reply of one earth station. Each earth station sends the reply data by using the assigned occupied band. Since the occupied band of the reply person is narrower than that for the multiple access data, the transmission speed should be slower than the divided number, but it is no problem because the quantity of reply data per station is very less than the multiple address data in general.

IPC: B29K101/10
Filed: 1983-06-20
Abstract: PURPOSE:To prevent remaining under an unreacted state of the cull of a resin in a pot, etc., and to shorten one-time resin sealing working time by forming a plunger in double structure consisting of an internal section and an external section arranged on the outside of the internal section so as to be positioned on the same axis as the internal section. CONSTITUTION:When a resin tablet 5 is charged into a pot 3 and the external section 6b of a plunger 6 inserted into the pot 3 is dropped, a mainly peripheral section heated and fluidized by a top force 1, a bottom force 2 and the external section 6b in the resin tablet 5 passes in a runner and is extruded into a cavity. When the internal section 6a of the plunger 6 is dropped immediately after or before the dropping of the external section 6b is completed, the residual resin tablet 5 except fluidized one passes in the runner 7 and is extruded into the cavity. Accordingly, a resin is extruded by the plunger 6 while a resin 5 remaining in the pot 3 sufficiently reacts and cures in a very short time after the completion of a final dropping up to a predetermined position of the plunger 6.

Abstract: PURPOSE: To ensure a use of the shift velocity of each axis to its full range of allowed velocity and thus exhibit sufficiently the capacity of the shift velocity, by providing the compound shift velocity clamping part of each axis corresponding to the shift direction of each shaft.  
     CONSTITUTION: The compound shift velocity command value F plus the X and Y axes shift extent command values LX and LY are applied as the shift command data 10. And thus the allowed velocity setting parts 24 and 28 deliver the clamping velocities FCX and FCY, At the same time, a compound operation is given to the command values LX and LY at the compound shift extent operation part 32 to obtain the compound shift extent command value L. The X axis compound allowed velocity operation part 26 gives an operation to the X axis compound allowed velocity FXC by the velocity FCX and the command values LX and L; and in the same way the Y axis compound allowed velocity operation part 30 gives an operation to the Y axis allowed velocity FYC to then deliver it. These two outputs are judged by the judging unit 16, and the lower speed is delivered in the form of the clamping velocity FC. The judging unit 18 gives a judgement between the velocity FC and the command value F, and then the lower velocity is supplied to the driving part in the form of the execution velocity F e . In such way, a highly efficient working control becomes possible.
