Title: Line controller for facsimile equipment with telephone set
Inventor: TAKAMI YOSHITAKA
IPC: H04M11/00
Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To provide a line controller for a facsimile equipment with a telephone set which does not cause any sense of incongruity to an opposite party in the case of a telephone call and conducts sure communication in the case of a facsimile call. SOLUTION: When a call is received, a line control section and a network control section or the like receive the call automatically and then a self-ring generator or the like starts a reply (step S105). Then a main control section discriminates whether or not a CNG signal is to be detected based on a detection state of a MODEM (step S110). When the main control section detects the CNG signal, the main control section stops production of a ring-back tone (step S115). Since a prescribed period is set to be a pause period of a silence state to facilitate detection of a succeeding CNG signal, a telephone caller hears the ring back tone so as to avoid a sense of incongruity, and detection of a CNG signal with respect to a facsimile call is facilitated to surely start facsimile communication.

Title: Image reader
Inventor: TSUNEKAWA TOKUICHI
IPC: H04N1/409
Filed: 1987-04-30
Abstract: PURPOSE:To quickly eliminate a noise component from an inputted analog picture signal to output a picture signal of high quality by detecting the value of the photoelectrically converted analog picture signal to vary the time constant of a low-pass filter. CONSTITUTION:A discriminating means 1 which discriminates the level of the analog signal outputted from a photoelectric transducer and a time constant varying means 1 which compares the level of this analog signal discriminated by the discriminating means 1 with a preliminarily set reference level to variably set the time constant of a filter means 2 are provided. If the output level of the analog picture signal outputted from the photoelectric transducer is lower than the reference level, the time constant of the low-pass filter 2 is extended to eliminate the noise and the gradation is improved; and if the output level of the analog picture signal is higher than the reference level, this time constant is reduced to eliminate a high frequency noise. Thus, the image output of high quality is outputted in a short time with a small number of times of detection.

Title: Pressure reducing device of steam
Inventor: KUNISADA HIROSHI
IPC: F01K3/00
Filed: 1983-06-14
Abstract: PURPOSE:To enable to decrease the energy loss during the pressure reduction by a structure wherein a bypass piping is provided with respect to a main steam piping led to the demand side and a steam turbine is arranged in the bypass piping so as to reduce the steam pressure just before the demand down to the pressure required at the demand side by passing a part of steam through the steam turbine. CONSTITUTION:A pressure indicating controller 21 controls valves 2 and 3 so as to obtain steam pressure required at a demand 22 side. However, because the pressure reduction by a pressure reducing valve 2 causes energy loss, the degrees of priority of the valves 2 and 3 are determined in their controlling so as to pass steam as large as possible through a bypass piping 18 in order to reduce the pressure of the steam at a steam turbine 4. In this case, the valve 2 may be fully open, if the steam pressure used at the demand 22 side permits. On the other hand, a flow indicating controller 19 measures the steam flow rate in a main steam pipe 17 and leads the steam exceeding the maximum steam flow rate passing through the pressure reducing valve 2 into an accumulator 5 so as to back-up in response to the increase of the required steam amount. Thus, the energy loss during the pressure reduction can be decreased and yet can be recovered as effective energy.

Title: Frequency sharing antenna
Inventor: CHIBA MASAKI
IPC: H01Q21/30
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To provide a compact and light-weight frequency sharing antenna which can receive signals of high and low frequency levels with high characteristic by using the antenna as a Gregorian or parabolic antenna according to the frequency bands. SOLUTION: When a high frequency feeding part 6 is stored by a drive mechanism 7 that is provided on the back of a secondary reflector 2, the radio signal received by a low frequency feeding part 5 is reflected by a main reflector 1 and transmitted to the reflector 2 after the signal is once focused at a 2nd focal point 4. Then the radio signal is reflected by the reflector 2 and focused at a 1st focal point 3. Thus, the operation of a Gregorian antenna is secured. In such cases, the size of a center aperture part 8 of the reflector 2 can be sufficiently reduced in comparison with the wavelength of the frequency band received by the part 5 due to the reduced wavelength of the reflector 2 caused by its sufficiently high receiving frequency.  When the phase center of the part 6 is moved to the point 4 by the mechanism 7, the radio signal received by the part 6 is reflected by the reflector 1 and focused at the point 4. Thus, the operation of a parabolic antenna is secured.

Inventor: KAMIMURA FUMIYA
IPC: H03D7/14
Filed: 1989-04-24
Abstract: PURPOSE:To provide a linear characteristic in a signal input section and to improve the mutual modulation characteristic by adopting a balun coil to the signal input section and varying its mutual induction coefficient and its reactance. CONSTITUTION:A connecting point between emitters of transistors(TRs) Q1 and Q2 and a connecting point of emitters of TRs Q3 and Q4 are connected to balancing side terminals of a balun coil L respectively, from which signals with opposite phase are outputted. Moreover, one terminal of non-balancing side of the coil L connects to the input signal terminal E and the other terminal connects to ground via a resistor R6. When the input signal from the terminal E is inputted, signals of opposite phase appear respectively the balanced side with the coil L and an intermediate frequency output signal is obtained between frequency conversion output terminals C and D. Since a signal without distortion is obtained at the signal input section, the production of cross modulation distortion in the input section is prevented and the gain or the like is changed by varying the mutual induction coefficient of the balun coil and the reactance.
