Title: Output control circuit
Inventor: OKASAKA YASUHIKO
IPC: H03K19/0175
Filed: 1987-10-15
Abstract: PURPOSE:To eliminate the time delay at the time when an output is varied from a high level to a low level by suppressing the generation of ringing at the time when a state of the output is varied from a high level to a low level. CONSTITUTION:When a read-out data RD 1 is varied from a high level to a low level, an output of a NOT circuit 8 becomes a low level and an nMOS 10 becomes a non-operating state, and an output of a NOT circuit 9 is in a high level, therefore, nMOSs 11, 14 operate. In this case, by a high level output of an output terminal 15, an nMOS 12 becomes an operating state through the nMOS 14. As a result, the output quickly a low level. When the output becomes a low level, the nMOS 12 becomes a non-operating state through the nMOS 14, and the output becomes slowly a ground level. By having such an output characteristic, ringing which is generated at the time when the output has been varied from a high level to a low level can be suppressed.

Filed: 1991-09-13
Abstract: PURPOSE:To improve the maximum contrast and improve the durability by a decrease in the minimum light emission brightness by providing a glass case with a filter which transmits only the spectra of the light emission colors of light emission sources. CONSTITUTION:Light emitting elements 2 are arrayed on the screen of 'Jumbostron(R)' in matrix and the light emitting elements 2 are provided with 'Trinilite(R)' cells 3 in matrix. The 'Trinilite(R)' cell 3 is constituted by arranging fluorescent materials 4 of blue, red, and green lontgitudinally in a glass case 5. Filters 6 which transmit only the spectra of the respective fluorescent materials 4 are printed on the external surface of the glass case 5 opposite the fluorescent materials 4. Therefore, only the light emission spectra of the light emission sources are transmitted through the filters 6, so the glass case 6 becomes nearly a complete black body for light except the spectra that external light contains and reflected light is extremely reduced. Consequently, black spot caused by the external light is eliminated and a high contrast is obtained.

Abstract: PURPOSE: To utilize the branch history to not only take out an instance to a cache but also forecast a cache miss by providing a wide band branch history table means, a local branch history table means, a prefetch means, etc. CONSTITUTION: A cache 12 supplies instructions and data to be used by a processor 10, and memory blocks are stored in every row. When there is no next data row, a prefetch mechanism 22 determines which row should be read out to the cache in advance based on a branch instruction in the instruction sequence. That is, a next row address register 20 determines the next row to be addressed by the input from the mechanism 22 and the input from a buffer taking-out address register 14 and gives the address of the new row to be next referred to a wide band branch history table 21. Next, a local branch history table 15 controls instruction fetch from the cache 12 by the output of the table 21. Thus, prefetch to the cache 12 is possible, and a cache miss is forecasted by all branch entrance analysis of a certain row.

Title: Signal-recording/reproducing apparatus
Inventor: TAKAHASHI AKITO
IPC: G11B15/02
Filed: 1994-10-27
Abstract: PURPOSE: To prevent the waste of electricity when one fails to turn OFF a power source, by turning OFF a power source circuit when a signal from a television set is not detected for a predetermined time. CONSTITUTION: A detection signal from an image signal-detecting circuit 2 is inputted to a power source circuit-controlling circuit 3. When the detection signal changes from an H level to an L level, an output, of the circuit 3 alike changes from the H to L level after the lapse of a fixed time determined by a resistor and a capacitor in the circuit 3. The circuit 3 consequently detects that the detection signal output from the circuit 2 is in the L level for a predetermined time. When the circuit 3 detects the L level for the predetermined time, a solenoid switch 4 is turned into an OFF state, thereby bringing a main power source rectifier circuit 6 and a sub power source rectifier circuit 7 into tone OFF state to shut off a power source. In this manner, the power source is prevented from being left in the ON state or the subsequent, waste of power is avoided.
