Title: Subscriber line transmission system
Inventor: HIRATO AKIRA
IPC: H04L25/49
Filed: 1983-04-13
Abstract: PURPOSE:To prevent generation of sag by using a high speed clock pulse in a subscriber line transmitting simultaneously a DC power. CONSTITUTION:When a data is inputted to a terminal 3, the data is latched by a clock inputted to a clock terminal 5 and a signal 3 is given to a flip-flop FF1. Further, the signal is ANDed with the high speed clock pulse from a terminal 4 by a gate A and output signals 6, 7 to form a bipolar waveform signal are outputted to a flip-flop FF2. The signals 6, 7 are impressed to AND gates, B, C respectively and a fast bipolar waveform signal is obtained by gating the AND gates by the signal 3. Thus, the transmission is attained without causing sag.

Abstract: PURPOSE:To eliminate an erroneous input and an erroneous action by setting the combination of the number of times and the time to contact a special input scope provided at a touch panel with a finger, comparing the combination and the input from an input means and controlling equipment when both are coincident. CONSTITUTION:It is judged whether or not a finger 4 of a user is brought into contact with a touch panel 2, and at the time of the contacting, in the same way as a hand-written character input, the fetching of the coordinates, which are the contacting position of the finger 4 of the user, is repeated. Here, when the user correctly carried out the contact with his finger 4, namely, when a special input scope 6e is connected twice in a row within 3sec, the fetching of the coordinates which are the contacting position of the finger 4 of the user, is repeated in order to judge whether or not a next contacting is executed. When the dust and insects in a home are stuck and contacted to the touch panel 2, it is ordinary that the contacting of two times is not executed within 3sec. In such a case, an abnormal input is considered, the return is executed to an input waiting condition from the touch panel 2 and an erroneous input is prevented.

Abstract: PURPOSE: To attain a removable shielding member for an automobile window or the like by affixing a self-adhesive film attached to the lining layer of a complex to a shielding surface after removing a protective layer, and removing the lining layer from the back surface of the self-adhesive film after affixing the film completely. CONSTITUTION: A transparent area 2 is unidirectional; only one way is transparent between a dim side A and a bright side B, and the side A is the inside of a vehicle and the side B is its outside. A film 1 is covered with a lining layer 3 which is brought into close contact with the non-adhesive surface of the film 1, and the adhesive surface of the film 1 is covered with a protective layer 4. The protective layer 4 is applied so as to prevent a surface corresponding to the film 1 from impairing the adhesive surface of the film 1 at the time of peeling-off. For application of a shielding member, the protective layer 4 is peeled off wholly or partially at the time of application of the film 1, so that the film is applied so as to be brought into close contact with a window-glass.  The protective layer 4 is continuously peeled off and the film 1 is applied to a window glass one after another. After the film 1 is brought into close contact with the window, the lining layer 3 may be removed. As a result, only the intermediate areas 71 to 74 between completely transparent unidirectional transparent areas 61 to 66 become actually visible.
