Title: Distortion compensator
Inventor: ISHIWATARI HIDEYUKI
IPC: H03F3/189
Filed: 1991-09-26
Abstract: PURPOSE:To optimally determine the degree of coupling of a directional coupler and to obtain a highly efficient and large distortion compensation value by specifying the degree of the coupling of the 4th directional coupler in the neighborhood of alpha<1/2>/1+alpha<1/2> (letting alpha be U.etaM/etaS, and the first and third efficiencies be etaM and etaS, respectively). CONSTITUTION:Let the degree of coupling of the 4th directional coupler 7 be C, the ratio of the mutual modulation distortion component of an output signal from the first amplifier 3 to the main signal be U, and the efficiency of amplifier 3 and the efficiency of amplifier 4 be etaM and etaS, respectively. Then, let alpha be the parameter that is determined by the nonlinear situations of amplifiers 3 and 6, let the parameter be equal to U.etaM/etaS, and set the degree of the coupling in the neighborhood of alpha<1/2>/1+alpha<1/2> (let the ratio of the mutual modulation distortion component of the output signal from amplifier 3 to the main signal be U). After that, specify the distortion compensation efficiency and the distortion compensation amount. The degree of coupling of coupler 7 can be optimally determined by the adjustment of only setting the degree of coupling in the neighborhood of alpha<1/2>/1+alpha<1/2>, and further a highly efficient and large distortion compensation value can be obtained.

Title: Subscriber circuit system for telephone exchange
Inventor: KUWABARA YOSHITADA
IPC: H04M3/06
Filed: 1986-10-17
Abstract: PURPOSE:To simplify an off-hook detection circuit at the time of calling and incoming and to miniaturize equipments by sending a positive half period signal from a neutral point biased in the negative direction to a channel and using a negative half period signal for control signal transmission. CONSTITUTION:A call signal generator S shifts the neutral point of a call signal toward the negative side so that the signal voltage of a positive half period signal voltage sent to a line is increased and the signal voltage of a negative half period used a control means is to be lowered. By supplying the positive signal to a bell circuit of a telephone set TEL, a bell is driven by a charging current of a capacitor C7. Moreover, the negative signal activates a photocoupler PHC1, a transistor Q is conductive to form a changing circuit of the capacitor C7 and the bell is driven by the discharge current. When the telephone set TEL hooks off, the photocoupler PHC2 is operated and a L-level signal is outputted continuously onto a line (l), then a common controller CC detects it to recognizes the off-hook. The detection is detected by the operation of the photocoupler PHC2 even at the time of calling or response.

Title: Manufacturing control apparatus for semiconductor device
Inventor: HASEGAWA TAKESHI
IPC: H01L21/02
Filed: 1990-09-18
Abstract: PURPOSE:To obtain the manufacturing control apparatus, for a semiconductor device, by which a first working process can be shifted to a second working process quickly within the permissible time by installing a means to judge whether the first working process is to be started or not by taking into consideration the operation schedule and the permissible time of the second working process. CONSTITUTION:At a process by which the permissible time is available from the end of a first working process up to the working start of a second working process, a unit manufacturing apparatus 2 sends to a control apparatus 1 the end time of the first working process and the required time of the second working process at the start of the first working process. At an installation working plan memory 13, in the control apparatus, which stores the working schedule of an apparatus which executes the second working process, a detection circuit 14 investigates whether a lot for the first working process can start the second working process within the permissible time from the end of the first working process. When the process cannot be started, the control apparatus tells a first working installation not to execute the first working process. When it is judged that the working process can be executed, it tells the first working installation to start the working process. By using the control apparatus, it is possible to judge accurately and at high speed whether the working process can be started within the permissible time when the second working process is started.
