A take-up reel has a diameter equal to or more than 85 times a thickness of a veneer sheet wound thereon and equal to or more than 300 mm so as to be of a curvature of the take-up reel to reduce cracking in parallel to fiber orientations that occurs in winding a veneer sheet after drying on a winding surface of the take-up reel. A veneer reeling apparatus comprises: a take-up reel disposed in a veneer sheet reeling position in a rotatable manner; a drive roller disposed on the lower surface of the take-up reel, transmitting a driving force with a variable speed; a veneer dryer disposed upstream from the veneer sheet reeling position; a conveyor provided between the terminal end of the veneer dryer and the drive-roller in the veneer sheet reeling position; and a plurality of thread feeding mechanisms disposed at arbitrary spatial intervals along a length direction of the take-up reel for a veneer sheet, wherein a continuous dried veneer sheet or dried veneer sheets whose sizes are of a constant length or of a length at random are wound on the take-up reel to form a veneer roll with threads as guide by a frictional force of the drive roller. Further, pairs of two overlapping veneer sheets or sets of a pair of two overlapping veneer sheets and a single veneer sheet can be wound on the take-up reel in a composite form.

On a SIMOX substrate having a plurality of STI layers and first conductivity type semiconductor layers disposed in the row direction, a stacked-layer structure SS is formed on a gate dielectric film formed on the first conductivity type semiconductor layer, the structure SS being made of a first polysilicon film, a second gate dielectric film and a second polysilicon film. Second conductivity type source and drain regions are formed in the first conductivity type semiconductor layer on both sides of the structure SS. In a plurality of source regions adjacent in the column direction between the stacked-layer structures SS, a common source line CSL is formed which is made of second conductivity type source region connecting semiconductor regions, source regions and conductive films formed on these semiconductor and source regions.

A current charged into or discharged from a phase-compensating capacitor C1 in an output circuit is controlled by a level shift circuit so that the current is kept constant for input signals inputted to the input terminals IN+ and IN- of a differential amplifier circuit, and also a current charged into or discharged from a phase-compensating capacitor C2 is controlled by the current correcting circuit so that the current become equal to a constant current controlled by the level shift circuit, namely to a current charged into or discharged from the phase-compensating capacitor C1. Therefore, even if a quickly rising or falling signal is inputted into the differential amplifier circuit, the MOS transistor MP11 or MN11 is not set in an offset state, which prevents generation of an overshoot or an undershot in the output terminal.

Screen data consists of two sets of field data. Each set of field data is divided into a plurality of data blocks which has four rows of pixel data corresponding to four rows of pixels vertically arranged. Every data block corresponding to one set of field data is stored in the first bank (bank0) of a frame buffer memory while that corresponding to the other set of field data is stored in the second bank (bank1). One row address is assigned to each data block. Bank1 is precharged while bank0 is in a write operation and vice versa in order to carry out the precharging operation and the write operation concurrently, so that the pixel data can be transferred at a high data transfer rate and each of two sets of field data can be transferred independently.

Instructions of a program are stored at addresses sequentially designated in accordance with an M series pseudo-random number sequence in an instruction memory in the order of program addresses. A pseudo-random number program counter has a feedback shift register for generating the same M series pseudo-random number sequence and applies an address of an instruction to be read from the instruction memory to the instruction memory based on a generated pseudo-random number, and a jump address and a select signal from an instruction decoder. As a result, instructions are read from the instruction memory and executed in the order of program addresses. The feedback shift register can be implemented as a small-scale circuit and operable at high speed.

In a semiconductor integrated circuit device having a data latch function, one of two inverters constituting a data latch circuit is formed of a PMOS transistor and an NMOS transistor, with the source terminal of the NMOS transistor being connected to a terminal for applying a reset signal. The reset signal is applied to an inverter through the NMOS transistor, and the inverter inverts the reset signal and resets the data latch circuit. Since one inverter of the data latch circuit is formed of the PMOS transistor and the NMOS transistor, the setting/resetting function of the semiconductor integrated circuit device can readily be implemented.

In a layout designing method for an LSI by a CMOS standard cell method, layout cells (standard layout patterns) which respectively correspond to logical function units are selected from a library. In this selection, the respective layout cells are selected from the library as patterns which are divided into p-type layout cells and n-type layout cells. The p-type layout cells and the n-type layout cells are arranged in accordance with a predetermined logical circuit diagram. Interconnection patterns for interconnecting the p-type layout cells and for interconnecting the n-type layout cells are arranged in accordance with the logical circuit diagram. An excessive interconnection region can be minimized, and efficient interconnections can be achieved. Therefore, an occupied plane area can be reduced in the layout design.

Signal generating means formed by variable line delay circuits 6 and 9 and dot delay circuits 7 and 8 receives a series of signal sample of a composite color television signal sampled in synchronism with a chrominance subcarrier at a frequency four times the chrominance subcarrier frequency and generates simultaneously a sample signal at a specified sampled point for separating a luminance signal and a chrominance signal and sampled signals at four sample points adjacent to the specified sample point, namely, four sampled points on the upper, lower, right and left sides of the specified sample point. A comparing and determining circuit 10 compares and determines a direction in which there is little change in the picture, based on the sampled signals at the adjacent sample points. Based on the result of determination of the comparing and determining circuit 10, a selector 11 selects and provides two sampled signals 110 and 111 existing in a region where there is little change in the picture. A separation filter 12 separates a chrominance signal 105 from the sampled signal 102 at the specified sample point using the two sampled signals 110 and 111 provided from the selector 11. A subtractor 5 subtracts the chrominance signal 105 from the sampled signal 102 at the specified sample point so as to provide a luminance signal 106.
