Abstract: Compositions and methods for developing quinone diazide positive-working photoresists. The compositions consist essentially of an aqueous solution of a tetra­alkylammonium hydroxide and an adjunct having a structure selected from:
      wherein n is 0 or 1; m is 1 or 2; and each R¹ and R² is independently selected from hydrogen, methyl, or ethyl, but in Structure I the two R²'s are not both ethyl. The addition of this adjunct prevents the formation of irregular deposits on the edges of unexposed portions of the photoresist lines when the photoresist is developed, increases the uniformity of line widths of photoresist lines developed according to the present invention, and increases the process latitude of the developer.

Abstract: A signal ( WE ) externally supplied to determine operation mode is supplied to a first buffer circuit (13). A  CAS  signal is supplied to a second buffer cir­cuit (14). The signals whose levels are converted by the first and second buffer circuits (13 and 14) are supplied to a mode selection circuit (15). The opera­tion of the mode selection circuit (15) is controlled by a  RAS  signal, and it latches and outputs a mode selection signal based on the outputs of the first and second buffer circuits (13 and 14). An externally supplied address signal and an address signal formed in the device are supplied to address buffer circuit (16). The address buffer circuit (16) selects one of the received address signals based on the  RAS  signal and the mode selection signal output from the mode selection circuit (15). A selected one of the address signals is supplied to a word line selection/driving circuit (17). When a mode other than the auto-refresh mode is speci­fied, the mode setting signal ( WE ) is set up before the  RAS  signal is activated. The set-up allowance time (t S ) with respect to the activation timing of the  RAS  signal is set to be larger than the minimum value (t ASRmin ) of the set-up allowance time (t ASR ) of the external address signal. The mode setting signal ( WE ) is latched by the mode selection circuit (15) when the  RAS  signal is acti­vated. The latched signal is used to select and control the operation mode.

The first and second storage portions and circuit blocks have a sequential diagnostic operaton mode in which the circuit blocks are sequentially diagnosed according to a diagnosis starting signal, and a scan operation mode in which a specific one among the circuit blocks is selected and diagnosed. The scan operation mode is realized during the supply of the diagnosis starting signal and by supplying selection signals that select the specific one among the circuit blocks.

Abstract: A method and system are disclosed for performing a leading 0/1 an­ticipation (LZA) in parallel with the floating-point addition of two operands (A and B) in a computer to significantly reduce the Addition-Normalization time. A combinational network is used to process appropriate XOR (P), AND (G), and NOR (Z) state signals re­sulting from the comparison of the bits in corresponding bit posi­tions of the operands (A and B), starting with the most significant bit (MSB) side of the addition. The state of the initial state signal is detected and shift amount signals are produced and counted for each successive state signal detected, as long as the state remains TRUE. When the state becomes NOT TRUE, adjustments are made depending on the initial state and the successive state, and production of the shift amount signals is halted and an adjustment signal is produced. To determine the exponent of the sum of the floating-point addition, the shift amount count is summed with the adjustment signal. The latter sum will be the exponent of the sum of the operands thus providing a normalized result. The adjustment signal may be based on the CARRY at the NOT TRUE bit position, and the state at the NOT TRUE position may be used to determine whether the result of the addition is positive or negative. 
     In addition to a serial network, an implementing network of a par­allel form which accepts appropriate state inputs as blocks of n bits in length, is disclosed, along with certain special implementation.

Abstract: A method and apparatus are described for preventing a dual deck video recorder from being used to record a copy-protected video signal. A switch (43) is included on the recorder to indicate whether a video signal input to one of the deck locations for recording originates externally of the machine or internally at another deck location. Recording is prevented whenever the switch indicates that the video signal originates from the other deck location if the video signal at such location includes a selected copy-protect signal. If a video signal to be recorded comes from externally of the machine, copying of the same is prevented if (1) the video signal includes the copy-protect signal; or (2) the video signal to be copied is the same as the play back video signal and the latter has the selected copy-protect signal.
