Abstract: An elastic store memory circuit includes first and second elastic store memories (10, 11). Each of the first and second elastic store memories generates a phase comparison signal (PCO) when a phase difference between a write timing and a read timing is within a predetermined phase range. The elastic store memory circuit also includes a selector (14, 15) which selects either the input data read out from the first elastic store memory or the input data read out from the second elastic store memory, and a slip signal generator (13) for generating a slip signal (SLIP+, SLIP-) on the basis of a write reset timing at which the first and second elastic store memories are reset, a read reset timing at which the first and second elastic store memories are reset, and the phase comparison signal. The slip signal indicates which one of the write reset timing and the read reset timing precedes the other one.

Abstract: A method of and an apparatus for forming finished cups of expanded resin of the present invention employ a transfer mold capable of transferring a preformed article obtained through a preforming process to the female member of a finish-forming mold, and simultaneously collecting from the male member of the finish-forming mold a finished article obtained through compression forming and discharging it after an inspection process, and enable a first process where the transfer mold receives a preformed article through a feeding device, a second process where the finished article is discharged from the transfer mold to a sorting device wherein conforming articles are counted and stacked, and a third process where another preformed article is heated and compressed within the finish-forming mold, to be conducted simultaneously. Further, a fourth process where the preformed article is transferred by the transfer mold to the female member of the finish-forming mold, and a fifth process where the finished article is transferred from the male member of the finish-forming mold to the transfer mold can be conducted simultaneously. Also, a sixth process where the conformity of the finished article is checked, and a seventh process where defective articles are removed and conforming articles are counted, are executed while the   transfer mold is moving. The time required to perform all the processes is thus significantly reduced.

Abstract: The present invention implements self testable boundary logic by using a tristate pass gate (60)and a tristate receiver (70)in combination with a linear feedback shift register (30), a storage register (120), and level sensi­tive scan design (LSSD) techniques. The linear feedback shift register (LFSR) shifts data into a storage register which is connected to the data inputs of the boundary logic through the tristate pass gate. The outputs of the tristate input receiver are also connected to the inputs of the boundary logic so that the boundary logic can receive data from both the data input of the integrated circuit (data path) or from the storage register connected to the LFSR. The tristate pass gate and receiver are enabled through a self test signal such that when the pass gate is enabled the receiver is not enabled and vice versa. In this way the boundary logic can only get data from either the storage register or through the receiver but not both. In this configuration data from the storage register can be input into the boundary logic without going through a multiplexer in the data path and incurring the associated delay. The boundary logic can then be self tested using ordinary LSSD techniques. This self testing can also be performed with a minimum of additional silicon area being used for the self test structures.

Abstract: An EEPROM cell is implemented by a field effect transistor comprising a channel layer (14) of an intentionally undoped gallium arsenide, a carrier supplying layer (15) formed on the channel layer and of a heavily doped n-type aluminum gallium arsenide having deep energy level, and a gate electrode (17a(17b)) formed on the carrier supplying layer, in which the deep energy level causes a current-voltage collapse phenomenon to take place due to trapping hot electrons injected from the channel layer to the carrier supplying layer in the presence of a stress voltage of about 1.2 volts between the source and drain for minimizing channel conductivity, and in which the stress voltage of about 3 volts ionizes the deep energy level so as to allow recovering from the current-voltage collapse phenomenon, thereby providing the low and high channel conductivities to two logic levels.

Abstract: Column direction transfer sections (51-58) provided every photosensitive element trains are such that the transfer direction of the odd columns and that of the even columns are opposite to each other. A conversion section (115, 116) for reversing the transfer order is connected to at least one final transfer stage of the column direction transfer sections, and charges transferred are thus transported to row direction transfer sections (119, 120). Thus, it is possible to transfer and output, in the same direction, signal charges transferred in directions opposite to each other every columns to the two row direction transfer sections in such a manner that those signal charges are distributed thereto. For this reason, the number of transfer stages of each row direction transfer section can be reduced to one half, the dimension every stage can be twice larger than that of the prior art, and the operating frequency can be also reduced to one half.

Abstract: Bit map data stored in an image memory (41) is read for each column by each M lines and is stores in a shift register (44) of M bits by N bits. The data in the shift register is differentiated in the direction of the column direction by edge detectors (45, 46) and extracted as data representing only a contour portion. This contour data is classified into forms of discontinuous points with respect to the horizontal direction and the vertical direction by classifying circuits. As for the classified data, the size of a dot to be printed and a printing position are converted by a determining circuit (49) to a pulse width and a timing at which the dot is to be generated, and the classified data is converted to a pulse width by a pulse-width modulating circuit (50) and is outputted to a laser beam modulating device. As a result, a dot smaller than a normal dot is added in a vacant portion, or a part of a normal dot is shaved, thereby printing a smooth pattern.

Abstract: To generate in-phase and quadrature components for digital signals, a Hilbert transformer for phase shifting by 90 DEG  and a delay element for equalising the signal transit time of the Hilbert transformer are normally used. The usable bandwidth is limited by the fact that the Hilbert transformer has nulls in the frequency response of absolute amounts at frequency 0 Hz and at multiples of half the sampling frequency. In the device according to the present invention, these nulls are avoided since symmetric filters with a phase shift of 45 DEG  and -45 DEG , respectively, are used for generating two signals in a quadrature phase relationship, which results in a reduced complexity of implementation whilst retaining the same bandwidth. <IMAGE>
