IPC: H04W92/18
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To allow the system to predict an end of speech to the user before an inter-slave-set direct speech limit time comes by monitoring an elapsed time of a speech from the start of the inter-slave-set direct speech and predicting the end of speech when the elapsed time reaches a warning time.

Filed: 1980-07-16
Abstract: PURPOSE:To prevent deterioration of resolution, by converting a one-dimensional picture to a two-dimensional picture once, and after that, projecting it to a two- dimensional image sensor. CONSTITUTION:An optical fiber flux 3 is constituted of a lot of optical fibers which have been arrayed linearly on one end and in the form of a plane surface on the other end, respectively. A plane surface end part 5 of the fiber flux 3 is placed so as to be opposed to a two-dimensional image sensor 7. Also, an optical lens is placed between the plane surface end part 5 and the sensor 7. In this way, a one-dimensional picture which has been caught by a linear end part 4 of the optical fiber flux is converted once to a two-dimensional picture in the plane surface end part 5, and after that, it is projected to the two-dimensional image sensor, and is photoelectrically converted. Therefore, comparing with the case when a one-dimensional image sensor has been used, deterioration of resolution is reduced.

Next group-dividing candidate points are extracted, and a consideration of an arrangement restriction for the extracted dividing candidate points is performed to decide a dividing position. Next element arrangement processing for each group is performed based upon the groupe divided result. Lastly the arrangement result being processed by each groupe is connected and a function block is completed. Also an analog and a digital elements is grouped individually. Thereby a superior arrangement form clone to a form by manual design can be made and a layout having less mutual influence between the analog-digital part can be realized.

Title: Analog switching circuit
Inventor: YOKOGAWA FUMIHIKO
IPC: H03K17/693
Filed: 1980-07-16
Abstract: PURPOSE:To use either of a bipolar transistor and a field effect transistor, by on- off controlling a current which is supplied to a voltage follower circuit, and providing a transistor for controlling a function of the voltage follower circuit. CONSTITUTION:A PNP bipolar transistor TRQ1 which is constituted of an emitter- follower is used for a voltage follower circuit 1, and a PNP bipolar TRQ2 is used for an on-off controlling TR. When a switch SW is off, the TRQ2 becomes an off-state, and it is stopped to supply a current to the emitter of the TRQ1 from a constant- current source I. Therefore, even if a signal is supplied to the base of the TRQ1, the emitter of the TRQ1 is kept to a ground level. When the switch SW is on, the TRQ2 is turned on, the constant-current source I is supplied to the emitter of the TRQ1, and an input signal is led out to an output terminal. Accordingly, a field effect transistor is used as the TRs Q1 and Q2.
