IPC: G11C11/02
Filed: 1979-04-23
Abstract: PURPOSE:To enable continuous readout at arbitrary time, by exciting the magnetic core with the exciting signal having the intensity not destroying the memory information, picking up the double higher harmonics from the output signal, and discriminating the binary information from the phase. CONSTITUTION:The unit consists of the memory circuit 1 using magnetic core, write-in circuit 2, exciting circuit 3, and discriminating circuit 4. The circuit 1 has four windings 6-9, the windings 6, 7 are used for write-in, the winding 8 is for excitation, and the winding 9 is for output. In the circuit 3, the reference signal P1 of the reference signal generator 20 is frequency-divided into 1/2 at the frequency divider 21, and the exciting signal P2 shaped into sinusoidal wave is output to the winding 8. The signal P2 is a fine current which does not destroy the memory content even if the circuit 1 is excited. In the synthesis circuit 36, when the output of the phase detection circuit 34 is 1 and the output of the phase detection circuit 35 is 0, the circuit 36 is at +1, and when the output of the circuit 34 is 0 and the output of the circuit 35 is -1, it is at -1. The discrimination circuit 33 produces the output of phase detection when the two input signals are +1 and 0, or 0 and -1.

Title: Gas safety confirmation device
Inventor: TANABE MINORU
IPC: G08B21/00
Filed: 1992-03-09
Abstract: PURPOSE:To prevent an accident caused by gas by associating an entrance door lock, a gas flow rate detection part, and an abnormal state decision part such as a fire sensor with one another. CONSTITUTION:The presence/absence state of a card 1 is detected and a presence/absence mode is set according to the detection result. In absence mode, a control part 4 inquires whether or not there is a gas flow rate of a gas flow rate detector 6 and when there is no gas flow rate, the control part 4 sets the electric lock 5 in a going-out wait state. When a resident opens the door and then closes it after exiting, automatic locking is performed. If a gas flow rate is detected in the absence mode, the electric lock 6 is disabled to be unlocked. Therefore, a gas plug is prevented from being left open forgetfully when the resident goes out. Further, the electric lock is unlocked in case of an emergency state such as a fire, so an accident due to confinement is avoided.
