IPC: H01L27/04
Filed: 1986-11-25
Abstract: PURPOSE:To classify and discriminate between LSI operating speeds that may be different among them because of the scattering of LSI internal element delays in operating time by a method wherein LSI operating speeds are determined by comparing a signal passing through an n-stage circuit that is a series connection of basic elements with a signal not passing through the circuit. CONSTITUTION:An LSI 1 is provided with a main functional circuit 11, an n-stage series connection circuit 12 that is a series connection of basic elements of a quantity (n), and a speed judging circuit 13 capable of detecting the scattering of delays in operating time among the basic elements through comparison of a first signal 100 passing the n-stage series connection circuit 12 with a second signal 200 not passing through the circuit 12. The speed judging circuit 13, upon detecting the scattering, transmits a speed-designating signal, high speed (H) or middle speed (M) or low speed (L), to the main functional circuit 11. The main functional circuit 11, responding to the speed designating signal H or M or L, chooses an optimal circuit for operation. An LSI of this design, which determines delays for the elements it contains and chooses an optimal circuit. Such an LSI is a high-performance product capable of a high-speed, middle-speed, and low-speed operations. This design improves the yield.

Filed: 1986-11-26
Abstract: PURPOSE:To easily detect a fault at the occurence of fault in its own station by comparing a received data with a transmission data processing and sending the reception data in its own station and detecting the fault through the result of comparison. CONSTITUTION:The reception signal from a loop transmission line is retarded from a delay circuit 5 so as to be matched in timing with the transmission signal outputted from a code conversion circuit 3 by a delay circuit 5 and the retarded reception signal and the transmission signal outputted from the code conversion circuit 3 are compared by a comparison circuit 7.

In the timing when the data is sent from the transmission/reception circuit 4, the comparator circuit 7 is controlled by a comparison control circuit 6 so as to avoid the comparison. The presence of a fault in its own station is detected from the result of comparison by the comparison circuit 7. That is, when the reception signal retarded by the delay circuit 5 and the transmission signal outputted from the code conversion circuit 3 are dissident, it is regarded that a fault takes place.

Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To easily change the position and size of a picture only by changing a relative address by converting an absolute address to the relative address deciding the picture in a display means and changing the relative address. SOLUTION: By changing the relative address, the picture is moved. An address changing part changes the relative address. In such a case, when the relative address in an area (c) in the picture is changed to '01', an image displayed in the area (b) is moved to the area (c). When the relative address is changed to '01', a controller of a display element constituting the area (c) selects a display signal having the relative address '01' from the display signal flowing on a signal transmission part to such up it. At this time, when the relative address of the area (b) is '01' as it is, the same image is displayed on the area (c) and the area (b). Also, the relative address may be changed temporarily or continuously.

Filed: 1989-11-01
Abstract: PURPOSE:To prevent interference between carrier pulleys from occurring by providing a mechanism to evade the interference caused by the carrier pulley when a carrier path consisting of the carrier pulley and a carrier belt is opened/ closed. CONSTITUTION:When an opening/closing frame 25 is opened along a locus 29 from a closed state, a roller 21 is moved along a main body frame 23. Since the main body frame 23 is set at a projecting state, the roller 21 and the carrier pulley 17 are moved in a direction of arrow head 26 centering a rotational center 24. When the carrier pulley 17 clears the carrier pulley 18, the roller 21 is separated from the main body frame 23, therefore, the roller 21 and the carrier pulley 17 are moved in a direction of arrow head 27. When they are moved in the direction of arrow head 27 to some extent, a sub frame 20 is abutted with a stopper 28, and the movement of the roller 21 and the carrier pulley 17 in the direction of arrow head 27 are stopped. In such a way, it is possible to prevent the interference between the carrier pulleys 17, 18 from occurring.

Abstract: PROBLEM TO BE SOLVED: To make it possible to switch an output impedance of an liquid crystal drive voltage output according to a load condition of a liquid crystal panel. SOLUTION: This liquid crystal driving power source circuit is composed of a reference voltage generation circuit 101 for forming driving voltages at plural levels, voltage-follower type buffer amplifiers 102, 107, 111 for converting V1, V2, and V3 in impedance, comparators 103, 106, 110 provided with input offsets for comparing the outputs of the buffer amplifiers with the inputs of the buffer amplifiers, and load circuits to the driving voltages controlled by the outputs from the comparators.
