Patent JP-S6243211-A (JP)
Title: Time constant circuit
Inventor: MASUDA NORITAKA
IPC: H03K17/28
Filed: 1985-08-20
Abstract: PURPOSE:To form a time constant circuit in a very small scale by connecting the 1st switch between a voltage source and the 1st capacitor, the 2nd switch between the 1st and 2nd capacitors and a voltage comparator to the 2nd capacitor respectively and turning on and off the 1st and 2nd switches alternately with each desired frequency. CONSTITUTION:When the 1st and 2nd switches 3 and 4 are turned on and of alternately, the terminal voltage of the 2nd capacitor 2 rises gradually. Then the voltage (v) of a voltage source 5 increases in steps with increase of the time (n). When the voltage (v) exceeds the threshold voltage Vth of a voltage comparator 6, a signal is delivered to an output terminal 7. Here a time constant is defined as gamma=(1/4f).(C2<2>/C1) and therefore the accuracy is decided by the ratio between the C1 and C2 and the Vth of the comparator 6 as long as the clock frequency has the satisfactory accuracy. As a result, the variance of the ratio between the C1 and C2 is extremely small despite the variance of their absolute values since both the 1st and 2nd capacitors 1 and 2 are produced close to each other on an integrated circuit and therefore in the same process.

Title: Call transfer system
Inventor: WATANABE TERUFUMI
IPC: H04M3/58
Filed: 1984-09-05
Abstract: PURPOSE:To prevent a transfer mediator from being bothered by dialing the inherent dial number corresponding to one of subscribers by other subscriber through a separate telephone set and exchanging and connecting a call party to the other subscriber through a connection supervisor device of a private branch exchange. CONSTITUTION:When a subscriber A executes the transfer retaining operation in the midst of calling between subscribers A and X, an address ADX of the subscriber X is developed by a call destination address development part 22, and is stored in a memory area MA corresponding to the subscriber A. Here, the development part 22 is a sort of a decoder, and converts dial information of the subscriber X into address data of a short bit length, which is easily stored in a memory 23. When the address data ADX is stored in the area MA, the subscribers S and B can be connected only through subscriber B's dial operation to access to the area MA from a neighboring telephone set.

Title: Controlling circuit for refresh access conflict
Inventor: SHINDOU KOUTAROU
IPC: G11C11/406
Filed: 1981-11-19
Abstract: PURPOSE:To decrease the access time and at the same time to give the assured control to the conflict between the refresh and access requests, by controlling an AND gate through which the access request signal passes via a flip-flop which accepts the refresh request and an access request monitor timer, etc. CONSTITUTION:No refresh request is given to a main memory MM via an OR circuit 4 when a refresh request accepting FF1 is not set or no output is delivered from an access request timer 3. Under such conditions, an AND gate 5 is opened by the FF1 and the timer 3. Then the access request signal is supplied to the memory MM via the gate 5. As a result, a delaying process for the set stabilizing timing of the FF is not required to decrease the access time. At the same time, a conflict is completely controlled between the access and refresh requests. Thus the refresh cycle is assuredly executed.

Title: Irreversible thyristor ward-leonard system
Inventor: TANIZAKI TOSHIMASA
IPC: H02P7/292
Filed: 1991-06-28
Abstract: PURPOSE:To eliminate control lag by forcibly setting the output of an integration amplifier at a level corresponding with a DC voltage at a time point when a controllable range detecting circuit is reset from an uncontrollable range to a controllable range. CONSTITUTION:When a current setting signal 10 makes a transition from positive to negative at time t1 and output current of a thyristor Ward-Leonard system goes zero at time t2, output of a controllable range detecting circuit 9 makes a transition from '0' to '1'. When DC voltage varies from V1 to V2 at time t4 and the thyristor Ward-Leonard system enters into controllable state at time t3, output of the detecting circuit 9 makes a transition from '0' to '1' to trigger a mono-stable flip-flop circuit 101. Consequently, a switch 102 is turned ON by an output pulse of the flip-flop circuit 101 to set the output of an integration amplifier 33 at a level corresponding to the DC voltage at that time point. Upon subsequent increase of gate firing phase signal 341 by means of an operation error signal 311 between a current command signal 22 and a current feedback signal 80, output current begins to rise.

Abstract: PURPOSE:To obtain a strong directivity by arranging an acoustic filter to suppress a primary sound wave to an opening, forming a sound source so that a sound wave is converged almost to one point and forming the acoustic filter so that the sound absorbing amount is increased at the circumference more than in the center. CONSTITUTION:Ultrasonic vibrators 1a being components of a sound source 1 are arranged so that a radiating face of a sound wave is formed to be recessed and the primary sound waves from the vibrators are converged almost to one point. The filter 4 is formed so that the sound absorbing amount at both left and right ends is larger than that in the middle, generation of a side lobe is suppressed and then a strong directivity is realized. The filter 4 mainly suppressed the primary sound wave and transmits the secondary sound wave. The effective length of the array is reduced by using the sound source 1 of this shape thereby reducing the 2 and then the entire size is made small.
