Title: Semiconductor logic circuit
Inventor: KANETANI KAZUO
IPC: H03K19/096
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To prevent misoperations and to attain the serial connection of simple single-phase dynamic logical gates by providing a pull-up p-type transistor whose source is connected with a VDD of which gate is connected with a first stage output node, and whose drain is connected with a second stage output node. SOLUTION: When an input is at an 'L' level (case 1), a first stage output node N1 is at an 'H' level, and a transistor MPZ does not conduct. Then, a second stage output node N2 is turned into an 'L' level via a delay time d2, since it is a finite pull-down time. When the input is at an 'H' level (case 2), the output node N1 is turned into an 'L' level with a delay time d1 similarly. The pre-charge output node N1 is in an 'H' level before the output node N1 is decided, and there is possibility that the output node N2 is discharged and turned into an 'L' level. Even in that case, when the output node N1 is turned into an 'L' level with the delay time d1, the second stage output node N2 is charged to a VDD ('H') by the transistor MPZ.

Title: Neutron shielding body and support construction thereof
Inventor: KUDO FUMIO
IPC: G21C15/02
Filed: 1988-06-08
Abstract: PURPOSE:To achieve a reduction in a leakage of a coolant by fitting an end fitting section formed at the bottom of a wrapper tube of a neutron shielding body into the outer circumference of an upper protrusion of a connecting tube sticking upward from a support plate of an upper core. CONSTITUTION:An end fitting section 10 is formed at the bottom of a wrapper tube of a neutron shielding body 51. A protrusion 11 sticking upward from a support plate 32 of an upper core is provided at the top of a connecting tube 37 and the fitting section 10 is fitted into the outer circumference thereof. A coolant of a low-pressure plenum 34 flows through a flow hole 38 drilled in the circumferential direction of the connecting tube 37 and then, into a wrapper tube via an outflow hole 39 opened at the protrusion 11. Even when the fitting section 10 is made of a ferrite-based steel while the protrusion 11 is made of austenitic stainless steel (with a coefficient of thermal expansion about 1.5 times as much as the ferrite based steel), a clearance 12 grows smaller between the fitting section 10 and the protrusion 11 with a rise in temperature by the start of operation of a reactor. This increases a passage resistance to reduce a leakage and also enables the maintaining of exchangeability for the shielding body 51.

Abstract: PURPOSE: To increase the key controllability by securing the sequence of the keys with no double keying in case plural number of the keys are hit virtually at one time and thus handling the key data effectively.  
     CONSTITUTION: In case plural number of keys are hit virtually at one time, control memory 8 reads out the coordinates of the 1st key from key matrix part 12 with the control given to memorize the key coordinates temporarily in register 13. At the same time, FF10 is set, and the pulses are inhibited from pulse generator circuit 1 via AND gate 11 to stop the operation of hexadecimal counter 2. After this, part 8 transfers the information of register 13 to memory 9 for memorization. Then the FF is reset with gate 11 opened, and the counting action is restarted for counter 2. At the same time, the reading is given for the next key. Thus the sequence of the key is kept with no double keying to handle the key data effectively. As a result, the key controllability can be increased.

Title: Echo canceller
Inventor: SAKAI YOSHIHIRO
IPC: H04B3/23
Filed: 1988-06-08
Abstract: PURPOSE:To apply proper adaptive operation stop control due to detection of double talk to make the converging state of an echo canceller stable by providing a circuit retarding a reception signal given to a reception level averaging circuit. CONSTITUTION:A delay circuit 16 retarding a reception signal by a delay time of an echo path 15 and giving the result to a circuit obtaining a reception signal level is provided. When the output of the echo path 15 is delayed by a time t1 more than the reception signal, the delay time of the delay circuit 16 is selected the same as the time 1. Since the input Sin is the sum of a transmission signal and the output of the echo path, the double talk detection period is equal to a double talk period. Thus, the converging operation of the echo canceller is made stable and the uncertain double talk control due to the delay in the echo path is improved.
