Abstract: PURPOSE:To realize a small and light-weight circuit and thus to reduce the power consumption without lowering the quality of talking as well as the nonlinear distortion by constituting the subscriber circuit with the electronic hybrid circuit using the operational amplifier and the semiconductor switch element. CONSTITUTION:The aural signals applied to terminal 203 via the exchange circuit are converted into a set of signals featuring the equal absolute value and different polarities via voltage follower 206 containing operational amplifier 216 plus reverse amplifier 208 containing operational amplifier 219 each, and then transmitted to subscriber's terminals 200 and 201 via 1st and 2nd resistors 207 and 209. At the same time, part of the signals to be supplied to subscriber's terminals 200 and 201 is supplied to other terminal 204 of the exchange circuit via differential amplifier 202 and subtractor circuit 205, and then a loop is formed to the subscriber circuit via the exchange circuit. Then terminal 203 is connected to circuit 205, and the echo, the singing and the like occurring to the loop of the subscriber circuit and the exchange circuit can be prevented by circuit 205. Thus the talking quality is maintained.

Title: Mechanical translating device
Inventor: OKUNISHI TOSHIYUKI
IPC: G06F17/28
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To obtain a natural translating sentence by recognizing plural morphemes as one phrase so as to execute translation. SOLUTION: When an input sentense includes tag information, a tag information erasing part 8 executes processing for erasing a tag from the input sentence after a required value is set in a tag storage memory 3c for the respective tags. Then, a tag translating part 10 is started and the processing is shifted to the one for executing the tag translation with the tag within a designated range of words and phrases. The whole sentences stored in a text buffer at first are moved to a whole sentence text buffer memory 3d and stored in the original buffer. When a translation processing is started in this state, the sentence stored in the text buffer becomes a translation object, a normal mechanical translation processing is executed and a translated sentence is obtained. Then, it is stored in a tag translation result buffer memory 3e.  A 'tag start position' in the text is stored in the tag translation result buffer memory 3e together with a 'tag translation result'.

IPC: H01F1/22
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To enable reducing magnetic loss by specifying the composition amount of Fe2O3, NiO, CuO and ZnO which are main component and SiO2 or MnO which are admixture to the main component. SOLUTION: As main component composition, 43-50 mol% of Fe2O3, 10-40 mol% of NiO, 1-15 mol% of CuO and residual ZnO are used, and at least one kind out of 0.005-0.1 wt.% of SiO2 and 0.005-0.5 wt.% of MnO is added as admixture, thereby obtaining low loss oxide magnetic material. The mean crystal grain diameter of a baked member is set at least 5 μm, and the ratio of pores in crystal grains to the whole pores is set as 5-60%, so that oxide magnetic material of lower loss can be obtained. Since resistivity is remarkably high, direct winding of a coil is enabled, and a jig for winding like a bobbin is unnecessary. Since the resistivity is high, collective baking with magnetic material is possible, and microminiaturization is enabled.

Title: Magnetic searching signal processor
Inventor: YOSHINARI HIROYUKI
IPC: G01V3/08
Filed: 1988-04-27
Abstract: PURPOSE:To especially improve the searching timing of a magnetic body by detecting a noise level preceding the magnetic body detecting signal of a magnetic searching device which detects magnetic bodies and a signal rising level subsequent to the noise level. CONSTITUTION:An arithmetic operation controller 21 calculates the sum of the peak-to-peak value (b) of the output of the magnetic searching device during the period t4-t5 and the peak-to-peak value (c) during the period t5-t0, namely, (b+c) is calculated as a signal rising level. After calculation, the controller 21 executes the calculation expressed by the formula and discriminates whether or not a magnetic body is detected from a calculated result. Since the signal level of magnetic body detecting signals increases as time elapses when a magnetic body exists in the area where a flying machine passes through, the detecting timing of the magnetic body can be improved especially as compared with the conventional device by finding the ratio of the noise level to the rising level.

Title: Facsimile terminal
Inventor: SUJITA KENJI
IPC: H04M11/00
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To allow a variety of terminal adaptors to separate analog ports of which a telephone set and a facsimile terminal are connected respectively to make a speech even when the facsimile terminal receives a voice signal. SOLUTION: Detection of a facsimile signal is started to discriminate whether or not a signal from a caller is the facsimile signal after closing a line in terms of DC when receiving an incoming call from the line (S11). When detecting the facsimile signal from the line, a signal from the caller is discriminated to be the facsimile signal and the facsimile signal is received as it is (S12). In the case that no facsimile signal is detected from the line for a prescribed time, it is discriminated that the signal from the caller is not the facsimile signal (S13), a transfer request signal is sent to the line (S14). Upon the receipt of the transfer request signal, a terminal adaptor calls a telephone set connected to its analog port according to the transfer request signal.

Filed: 1983-06-13
Abstract: PURPOSE:To perform satisfactory welding by picking up the image near a groove with a camera prior to welding, deriving the weld line connecting the intermediate points of both groove walls of the groove and moving a torch. CONSTITUTION:A light source 13 is lighted and a torch 10 is moved along a groove 8 by a control part. The image near the groove 8 is picked up with a camera.

Filed: 1990-04-21
Abstract: PURPOSE:To ensure the movement to a wire breaking point at the time of returning to the wire breaking by carrying out profile process with larger amount of tool compensation than the initial amount, at the time of returning to a wire breaking point during machining. CONSTITUTION:When there is wire breaking of a wire electrode 1 in the middle of process, the number of wire breaking 1 is stored in a numerical controller 7, and a mode is changed over to a re-process mode, where, after the wire electrode 1 is cut, and the wire electrode 1 is automatically supplied after returning to a process starting point, so as to carry out connection. The process condition lower than the electric condition for rough process, registered in the numerical controller 7, is read, and then, the offset amount correspondent to the number of wire breaking 1 is read in the numerical controller 7, and after machining is continued to the wire breaking point of the wire electrode 1 for pre-process under the process condition and by an offset value, the process condition is changed over to an initial machining condition, and profile machining is continued. Since the process at larger offset amount than that for the pre-process is carried out during the restoration at time of wire breaking, a processed surface will not be deteriorated, and high accuracy is achieved.

Filed: 1988-04-28
Abstract: PURPOSE:To synchronize in phase the reference clock signal of horizontal transfer clock signals even when the frequency change is large by generating a reference clock signal of 6 fSC from an oscillating means to which an oscillating frequency tend to be pulled in following a change in an aimed frequency and comparing phases of both reference clock signals at a frequency higher than the horizontal scanning frequency. CONSTITUTION:Clock signals outputted from a 3-multiply circuit 46 are supplied to a phase comparator circuit 47 where the clock signals are compared with a reference clock signal outputted from an LC oscillation circuit 39 in phase. Then the voltage VC applied across a varactor diode 42 is changed in accordance with the phase-compared result. As a result, the oscillating frequency of the circuit 39 is controlled and a reference clock signal of 6 fSC is synchronized in phase to a reference clock signal of 4 fSC. Therefore, even when the oscillating frequency of a crystal oscillation circuit 31 largely changes, the oscillating frequency of the circuit 39 can be changed in accordance with the change in the oscillating frequency of the circuit 31 and the reference clock signal of 6 fSC can always be phase-synchronized to the reference clock signal of 4 fSC.
