Title: Terminal equipment with circumstance detecting function and telephone exchange system including the same equipment
Inventor: USUHA SHINJI
IPC: H04M3/42
Filed: 1989-05-02
Abstract: PURPOSE:To enable a calling subscriber to easily discriminate whether a called subscriber can respond or not even at the time when the called subscriber does not perform the absence registering operation or the like to a terminal equipment by providing the terminal equipment with a sensor which detects the peripheral circumstance state. CONSTITUTION:When a subscriber calls a terminal equipment 10 with the circumstance detecting function by an analog telephone set 40, an exchange 20 detects the call to the terminal equipment 10 to request sensor information detected by an optical sensor circuit 18 to the terminal equipment 10. The terminal equipment 10 sends 'bright' or 'dark' information from a signal detecting circuit 15 to the exchange 20 as sensor information. When the exchange 20 receives sensor information indicating 'dark' from the terminal 10, the exchange 20 sends a first ringing tone corresponding to it to the calling subscriber and when receives sensor information indicating 'bright', the exchange 20 sends a second ringing tone corresponding to it to the calling subscriber. Thus, outgoing of the called subscriber or the like is easily confirmed by the calling subscriber because the circumstance state on the side of the called terminal 10 is detected.

Filed: 1981-07-20
Abstract: PURPOSE:To collect fine particles and to prevent a reed valve from being clogged by providing a section of a large volume in the secondary air feed passage in a system where the secondary air is fed to an exhaust passage through the reed valve by means of the negative pressure due to pulsation of exhaust. CONSTITUTION:A reed valve 13 in the secondary air feed passage 7 is opened  to feed the secondary air to an exhaust port 3 in said device by utilizing the  negative pressure of pressure pulsations in an exhaust pipe 6 generated when an  exhaust valve 1 is opened and the exhaust gas in a combustion chamber 4 is  discharged into the atmosphere through the exhaust port 3, an exhaust manifold  5, and the exhaust pipe 6. In this case, an expanded volume section 8 is fitted  between passage portions 7a, 7b of said passage 7. The passage portion 7a, 7b  are connected to the volume section 8 so that their axes cross at a right angle  to each other, thereby the reverse flow of the exhaust gas is deflected in the  volume section 8 and the particules are separated from the gas by use of inertia  and gravity thus are prevented from being flown into the reed valve 13.

Abstract: PURPOSE:To attain highly stable detection at all times with high accuracy by providing a correction means detecting the movement of a picture and correcting the movement and detecting a focus based on a signal component whose movement is corrected by the movement detection means. CONSTITUTION:An X axis projection circuit 7 obtains an X axis component signal 8 from a moving vector obtained from a moving vector arithmetic circuit 6. an edge detection circuit 9 detects an edge from information such as a tilt with respect to a picture signal and selects an edge with a larger tilt with respect to the X axis as an edge for focus discrimination, for example. An edge calculation circuit 10 calculates the edge from the density difference of the edge and the tilt of the edge and outputs the result as an edge width signal 11. The signal 11 is subtracted from a signal 8 and the result is fed to a comparator 12, and the signal is a corrected edge width signal. The comparator 12 writes a smaller edge width signal to a memory 13 in two corrected edge width signals and gives a control signal to a lens control circuit 14. Thus, the deterioration in the accuracy such as an unsharpened edge is prevented.

Abstract: PURPOSE:To operate a valve without an increase in a valve stem of a packing portion more than required by providing a heat-resisting compression packing adapted to operate only at the time of a fire outside the conventional packing for sealing a fluid round the valve stem to be used in combination therewith. CONSTITUTION:In the normal use condition, a fluid between a valve stem 25 and a valve cover 16 is sealed by a soft packing 37. In this case, force pushing up a packing support 40 is generated, which is born by an annular disc 41 in the normal condition not to be transmitted to a heat-resisting compression packing 46. If a valve is subjected to an abnormal high temperature such as a fire or the like, the annular disc 41 is first fused due to a temperature rise of the valve to flow out to an escape space 42, so that support force opposite to the force pushing up the packing support 40 is lost, and the heat-resisting compression packing 46 is pressed to the valve stem 25 through the first adapter 47 by the push-up force to seal up a fluid round the valve stem 25.
