A semiconductor integrated circuit device includes a plurality of flip-flops configured to form a scan chain in a scan path test to operate as a shift register. The first flip-flop of the plurality of flip-flops latches a first input signal in synchronization with a clock signal, outputs a first output signal and fixes the first output signal based on the first selection control signal. A second flip-flop of the plurality of flip-flops latches a second input signal in synchronization with the clock signal, outputs a second output signal, and fixes the second output signal based on a second selection control signal. The semiconductor integrated circuit device further includes a control circuit configured to generate the first and second selection control signals such that a period during which the first flip-flop fixes the first output signal is different from a period during which the second flip-flop fixes the second output signal.

A semiconductor memory device comprises a word lines (15), pairs of complementary data lines (17, 18), memory elements (MC11) respectively arranged at each intersection of the word lines and the pairs of complementary data lines, pairs of complementary signal lines (17s, 18s) each associated with a sense amplifiers (SA) and selectively connected to one of the pairs of complementary data lines via a pair of transfer gate transistors (7, 8), first precharge means (5, 6) for charging the pairs of complementary data lines and second precharge means (19, 20) for charging the pairs of complementary signal lines. The second precharge means charge the pairs of complementary signal lines to a first voltage (V.sub.D), the first precharge means charge the pairs of complementary signal lines to a second voltage (V.sub.D -V.sub.t) which is smaller than the first voltage by a threshold voltage (V.sub.t) of the transfer gate transistors and the transfer gate transistors have their gate electrodes supplied with the first voltage. The transfer gate transistors are N-channel type MOS transistors and the first and the second precharge means include N and P channel MOS type transistors respectively.

摘要:
A control system for transmission devices equipped with a high-efficiency coding scheme in a communication network which avoids degradation of the quality of an acoustic signal for transmission and permits an efficient transfer of the acoustic signal. The control system has a structure in which: information on a high-efficiency coding scheme used in the preceding transmission device is sent to the current exchange from the preceding one through the use of an out-band signaling system for transmitting and receiving a call control signal via a channel different from a speech channel; and based on the information sent to the current exchange, second-placed transmission devices connected to the current and following exchanges avoid effectively decoding/coding of the acoustic signal transferred thereto, or the use of these transmission devices is avoided.

An addressing system comprises an address buffer unit responsive to a clock signal of a low level for latching an address signal indicative of one of word lines, and maintaining the address signal until the clock signal is shifted to from a high level to the low level again; an address decoder unit coupled with the address buffer unit for selectively driving decoded signal lines; a timing control unit responsive to the clock signal for producing an in-phase timing signal; and a driver unit having a plurality of driver circuits respectively coupled between the decoded signal lines and the plurality of word lines, wherein the plurality of driver circuits are operative to respectively latch logic levels on the associated decoded signal lines when the in-phase timing signal is shifted from the low level to the high level so as to selectively drive the address lines to active level, and maintains all of the word lines in inactive level while the in-phase timing signal remains in the low level, thereby preventing the word lines from multiple selection.

A cover for forming a space for coating is provided above an electroconductive belt conveyor for adjusting an electric field at an end portion of a flat plate-like object to be coated, electrostatic powder coating guns pointed at the object to be coated on the belt conveyor in the space for coating are provided, and means for introducing air into the space for coating and means for exhausting the air are respectively provided. As a result, the strength of the electric field formed from the electrostatic powder coating guns to the electroconductive belt conveyor and the object to be coated is made uniform through their entire surface so that the thickness of a powder layer to be adhered to the object to be coated is made uniform from its central portion to an end portion. Consequently, the waste of the powder coating material is prevented, and local cracks in a portion having a great thickness generated when the coated object is bent are prevented.

A powder coating booth a function of supplying air though its ceiling. Sidewalls of the booth is formed from an insulating material or a semiconductor. A belt conveyor is disposed at the bottom of the booth. An electric field is formed so that it extends from a paint gun to the conveyor belt. The majority of oversprayed powder paint produced during painting becomes attached to the upper surface of a portion of the conveyor belt, is carried, together with this belt portion, to the outside of the booth, and is recovered from the conveyor by a blowing-type of static eliminator, thereby minimizing the mount of oversprayed powder paint mixed in an exhaust of the booth drawn through the sidewall.
