Abstract: A process of forming electrodes and interconnections in a silicon semiconductor device comprises the steps of forming an insulating film on a silicon substrate, defining an opening in the insulating film, depositing a layer of metal having a high melting point on the insulating film, implanting ions to mix an interface between the metal layer and the silicon substrate, heating the construction in a temperature in the range of from 400 to 650 degrees Celsius to form a silicide of the metal layer in the opening, and selectively etching away an unreacted metal layer so as to self-align the silicide metal layer with the opening. The silicide metal layer is then annealed in a non-reducing gas atmosphere at a temperature ranging from 800 to 1,100 degrees Celsius.

Abstract: A television signal transmission system with stationary-picture transmission capabilities including the ability to stop picture transmission at any point within a picture frame. The picture stop feature is realized by inserting a control code within each horizontal scanning interval. The control code signals any of several instructions, including start, stop, scan and line control header instructions. The stop control code is generated in the horizontal scanning interval corresponding to the stop point in the frame transmission to thereby inhibit further picture transmission. Picture transmission is restarted by the generation of a scan control code.

Abstract: A semiconductor memory having a construction making it less susceptible to .alpha.-rays. The memory includes a pair of transistors connected in a flip-flop arrangement. In each memory transistor there is a buried region of high concentration which contacts the collector region of the same impurity. The base region consists of a relatively low concentration part, in which the emitter or emitters are formed, and a high concentration part, to which the base electrode is attached. The high concentration part of the base region extends down to and protrudes into the high concentration buried region, resulting in a higher than usual collector-base capacitance. The latter causes the voltage change due to .alpha.-rays to be less than it otherwise would be.

Abstract: In a Booth's algorithm multiplication circuit, a multiplicand is set in a multiplication register and a multiplier is set in a multiplier shift-register. Consecutive bits of the multiplier are applied to a Booth's decoder to produce coefficients, and the multiplicand and coefficient are multiplied by each other to produce a partial product. Partial products are produced for every three consecutive bits of the multiplier, and the obtained partial products are added to the sum of previously obtained partial products. After all the partial products are added together, the resultant sum is derived from the adder or from the feed-back path of the output from the adder.

The addressed communication unit, if operating responds with a reply frame including the destination address of the monitor, its address, and a status information field. The received status information is compared with a previously received status information from the addressed control unit, and a primary fault is indicated when the compared informations do not coincide. A secondary fault is indicated if no reply frame is received from an addressed communication unit within a predetermined time from the transmission of the inquiry frame.

Abstract: An inked ribbon cartridge has two sets of ribbon feed mechanisms, one for each core means around which the ribbon is wound, allowing the ribbon to travel back and forth so that the cartridge can be loaded upside down when the upper half of the ribbon has been used up thereby doubling the useful life of the cartridge. Two springs apply a predetermined force to two ratchet wheels which are connected to first and second core means for preventing an over-rotation of the core means. Each feed mechanism comprises a feed driven roller and a feed drive roller.
