Patent JP-S63187791-A (JP)
Title: Electronic exchange
Inventor: ODAWARA TAKESHI
IPC: H04Q3/54
Filed: 1987-01-29
Abstract: PURPOSE:To prevent an erroneous response by informing that an acquired trunk line is receiving an incoming call to a telephone set which acquires the trunk line just after the incoming call of the trunk line in a speech by a speech synthesis device. CONSTITUTION:When an incoming request is issued from the trunk line 3 a central controller 6 detects it and connects the trunk line 3 which issues the request with the speech path 5 of the telephone set 1 and at the same time it lights a trunk line lamp in a trunk line indicator 7, which receives the incoming call. And also the incoming ringing tone of the telephone set 1 is rung so as to inform a user that the incoming call of the trunk line is obtained. Next, if the central controller 6 detects that the user makes the telephone set 1 off/hook within one second after detecting the incoming request, the speech path 5 between the trunk line 3 and the telephone set 1 is disconnected and the telephone set 1 is connected to the speech path 5 of the speech synthesis device 8 so as to inform the user that the incoming call of the trunk line is executed in a speech. Thus, the erroneous response of the user can be securely prevented.

Title: Control circuit for field effect transistor
Inventor: ABE KIMIHITO
IPC: H03K17/687
Filed: 1982-02-08
Abstract: PURPOSE:To drive stably an FET in high speed, by providing a switch element short-circuiting a control electrode and a main electrode when the FET is turned off. CONSTITUTION:When a control signal is applied to a terminal VB, a transistor TR6 is conductive, a current charging a capacitance Ciss between the gate and source in an MOSFET1 from the positive polarity (marked.) flows and the FET1 is quickly conductive. When the control signal is interrupted and the TR6 is set off, the electric energy stored in a pulse transformer 2 is consumed in a circuit consisting of a resistor 41 and a diode 5. Since the exciting current appearing at a winding 203 conducts a switching element 14, the stored charges in the capacitor Ciss flow in a resistor 13 and are consumed quickly. Since the capacitor Ciss is not discharged by the exciting current, the charges are discharged at a constant time at all times with the resistor 13 and the turn-off characteristics are made stable. Since the exciting current is designed very small, the control circuit is designed in small size and small power.

Abstract: PURPOSE:To discriminate accurately the focusing state even for a subject having the periodical property by detecting an image formed by the beams separated after passing through three different regions of a photographing lens by means of a photoelectric element and giving the signal processing to the detected image. CONSTITUTION:The light delivered from a subject and passed through three different regions of a photographing lens 41 is separated after passing through an aperture 42 of a light shielding member 43 provided on the image forming surface of the lens 41, a field lens 44 at the back of the aperture 42, and apertures 45a-45c of a diaphragm 46 which are arrayed inequidistantly.
