Patent EP-0399258-A2 (EP)
Inventor: SAWADA KIKUZU DOERU HOSHINO RM
IPC: G11C29/00

Abstract: A semiconductor memory device having a self-correcting func­tion comprises a plurality of non-volatile memory cells (2) and first and second read circuits (5, 6) for reading bit data from the memory cells. Part of the memory cells (1a) store data, whereas another part (1b) store parity bits on the data. Each memory cell (2) selectively stores "0" or "1" by causing itself to be charged with an electric charge. The first and second read circuits (5, 6) receive a plurality of bit data from a plurality of selected memory cells in order to output correct data with correct parity. The criteria of detecting "0" and "1" in the first and second read circuits (5, 6) are set to different values, so that the first read circuit (5) detects a current value smaller than the value of the current flowing through the memory cell holding a bit error because of charge depletion, whereas the second read circuit (6) detects a current value greater than that value. Consequently, even if the variation of the threshold resulting from the charge de­pletion allows the presence of a faulty memory cell therein, one of the read circuits (5, 6) can make correct data read.

Abstract: This invention discloses a video signal processing circuit of a comb filter arrangement for separating and extracting a luminance signal and a chrominance signal from an input video signal including the luminance sig­nal and the chrominance signal. The input video signal is delayed by a delay circuit (11) by a 1H period, and a 1H-delayed signal is supplied to a band-pass filter (14). The signal having passed through the band-pass filter (14) is added to the original input video signal by an adding circuit (12). An output from the adding circuit is supplied to a trap circuit (15) and chromi­nance signal components are eliminated. Meanwhile, the signal having passed through the band-pass filter (14) is eliminated from the input video signal by a subtract­ing circuit (13), and an amplitude of an output from the subtracting circuit is attenuated by an attenuating cir­cuit (17). A signal corresponding to a period corre­sponding to an amplitude difference in the chrominance signal between the signal having passed through the band-pass filter (14) and the original input video sig­nal before delay is generated by a switching signal gen­erating circuit (20). A first switching circuit (16) switches the outputs from the adding circuit (12) and the trap circuit (15), and a second switching circuit (18) switches the original input video signal and an output from the attenuating circuit (17).

Abstract: Eine elektromechanische Terminuhr (42) mit einstellbarem Terminzeiger (48) vor 12stündiger Zeitanzeige, etwa eines Zifferblattes (44), soll ohne das Erfordernis aufwendiger mechanischer oder elektromechanischer, 24stündig arbeitender Stell- oder Schaltmittel dafür ausgelegt werden, noch nicht zwölf Stunden, sondern erst vierundzwanzig Stunden nach einer einmal eingetretenen Terminsignalgabe wieder ein Terminsignal (51) abzustrahlen. Dafür ist eine Blockier-Zeitschaltung (75) vorgesehen, die für etwas mehr als zwölf Stunden arbeitet, wenn sie mit dem manuellen Abschalten des Terminsignales (51) gestartet wird und vorzugsweise auf dem Zählen von Impulsen aus der zeithaltenden Uhrenschaltung (45) beruht. Diese Blockier-Zeitschaltung (75) wird auch zurückgesetzt, wenn ein anderer Terminsignalgabe-Zeitpunkt eingestellt wird - jedenfalls dann, wenn der neue Terminsignalgabe-Zeitpunkt in die Blockierzeitspanne (H) hineinverlegt wird. Der dafür vorgesehene Reset-Schalter (71) kann funktionell mit der Stell-Handhabe (73) für die Terminsignalvorgabe gekoppelt sein. <IMAGE>

Abstract: A primary direct current power source (10) is controlled by a thermostat (8) and a secondary direct current power source (32,34) is independent of the thermostat. A first relay (22) is in circuit with the oil burner motor (4) to energize the same and a second relay (24) is in series with the first and with an alternating voltage source for energizing the ignitor (6) of the furnace. An electronic circuit controls the first relay switch (122) and includes a pair of silicon controlled rectifiers (SCR's) (80,82) connected in series for energizing the first relay. A second electronic circuit includes a pair of inter­connected NPN transistors (102,112) for controlling the operation of the second relay switch (124). The first NPN transistor (112) is conductive when the second relay switch (124) is energized and the second NPN transistor(102) is connected to the first to turn "OFF" the same in response to flame being sensed in the furnace. A flame sensing element (30) in the furnace is associated with a control relay (128) for controlling a pair of relay switches, one of which (28) is in series with the SCR's and the other (38) is adapted to energize a redundant pair of time-delay circuits. Each time-delay circuit includes a capacitor (98) and a programmable unijunction transistor (PUT) (94) programmed to breakover at a voltage which is a function of a first predetermined time for charg­ing a capacitor and a resistance in the cathode circuit   of each PUT which provides for a second predetermined time for the discharge of the capacitor voltage to hold the second relay (24) "OPEN" by conduction through the second NPN transistor (102). Another electronic circuit includes an NPN transistor (72) and PNP transistor (74) connected to energize the first relay switch (122).

Abstract: A liquid crystal display device receiving television signals formed in accordance with interlace scanning method for displaying images is disclosed. 
     Numbers of the rows of pixels and of scan signal lines on a liquid crystal panel is increased to be the same as the number of valid scan lines of 1 frame of television signals. The original video signals to be inputted to the device are compressed to 1/2, and interpolating signals are added to every line of the compressed signals to form pseudo video signals. Shift register operation of a scan driver and the segment driver are done twice as fast as that in the conventional device, and start timing of the shift register operation of the segment driver is controlled to be shifted by 1/2 horizontal scanning period between the even field and odd field, while the pseudo video signals are applied to the segment driver. Consequently, to the rows of pixels to which original video signals are applied in the even field and to the rows of pixels to which interpolating signals are applied in the even field, interpolating signals and original video signals are applied in the odd field, respectively. Consequently, display can be carried out seemingly in accordance with the interlace scanning method.
