A full adder that operates rapidly with low power supply voltage and minimal power consumption, and further, that occupies a small area on a semiconductor element. A sum signal calculation circuit 10 of full adder 1 performs addition of input signals A and B and carry in signal C and outputs sum signal S.sub.out. Carry signal calculation circuit 16 outputs carry out signal C.sub.out corresponding to the combination of the logic values of input signals A and B and carry in signal C. Sum signal calculation circuit (10) is composed of addition signal generation circuit (12) and sum signal generation circuit (14). Addition signal generation circuit 12 performs XOR logic operations on input signals A and B. Sum signal generation circuit 14 outputs the results of full addition operations on inputs signals A and B and carry in signal C as sum signal S.sub.out, based on the results of XOR logic operations by addition signal generation circuit (12) and carry in signal C.

An image reading device capable of preventing, by increasing the quantity of light at the center or bound portion of a spread book document, the quantity of light from becoming short and preventing density from becoming irregular due to the deviation of a focus. At and around the center of a spread book document where the document is bound, the quantity of light for illumination or the amplification gain of image data read from the document is increased. A plurality of fluorescent lamps illuminate the surface of the document at the upstream side and downstream side with respect to an intended scanning direction. When the edge of the document is to be detected, only one of the lamps is turned on to enhance the stripe pattern representative of the stepped edge portion of the document.

The present invention relates to a method of manufacturing a circuit module through the use of a wireless bonding technique. In this invention, in order to achieve component assembly without experiencing thermal and mechanical stresses, in the circuit module manufacturing method in which an external electrode of a component and a conductor of a substrate are connected with each other according to the wireless bonding technique, the substrate has a laser beam transmissible property, and after the component is placed on an assembly surface of the substrate, a laser beam is applied from a surface of the substrate opposite to the assembly surface thereof to a connecting spot. The laser beam passing through the substrate heats the connecting spot so that the connection between the external electrode of the component and the conductor of the substrate is made by phase transition or diffusion.

A polyimide precursor composition which is produced by (i) providing a polyamide acid solution obtained by reacting an aromatic tetracarboxylic acid component and a diamine component in the presence of an oxygen-containing solvent and (ii) subjecting said polyamide acid solution to heat treatment. The polyimide precursor composition exhibits a desirable apparent viscosity and a desirable thixotropic property and it excels in film forming ability, and because of this, it enables the formation a high quality relief pattern film with no defect and which excels in form retention by way of the screen printing. Further, the polyimide precursor composition is extremely suitable for the formation of a relief pattern by way of the screen printing in production of electronic, electric, optical, or precision devices, wherein the relief pattern is required to have a reduced dielectric constant and a reduced residual stress and to have a sufficient heat resistance, moisture resistance, physical strength, and chemical stability.

A layer planarizing method for a semiconductor device is provided to attain excellent controllability of a polishing amount to form a uniform and flat layer on a non-uniform wafer in polishing in a wafer surface. According to the method, a first layer is deposited over at least a top portion of a stepped portion formed on a surface of a body, the stepped portion covered with the first layer is covered with a second layer having a higher polishing rate than that of the first layer, and the second layer is polished until the first layer deposited on the top portion of the stepped portion is exposed.
摘要:
A method for tracking, in a roaming receiver, RF channels in a multi-area system where each area has a unique RF channel and each unique RF channel has a unique address for each user. A plurality of telephone area codes are stored into a memory of the receiver with each of the telephone area codes corresponding to a different RF channel within the multi-area system. An address from the RF channel which is unique to the receiver for that specific RF channel is received by the receiver, each address corresponding to one of the stored telephone area codes. A telephone area code corresponding to the address is then retrieved from the receiver memory, and the telephone area code is displayed in a receiver display to allow a user to quickly recognize which area of the multi-area system the receiver is located within.
