Title: Manufacturing method for fet
Inventor: OONISHI TOYOKAZU
IPC: H01L29/812
Filed: 1981-04-30
Abstract: PURPOSE:To prevent gate withstand voltage capability deterioration by a method wherein ohmic junction layers are formed for source and drain by a method wherein ion implantation is effected with an inverted taper type Schottky gate electrode as a mask. CONSTITUTION:A GaAs substrate 1 is coated with a d1 thick film of a gate material, exemplifiedly MoSi2 or Ti0.3W0.7Si2 by exemplifiedly the multitarget sputtering method. An Si compound containing more Si being etached at a higher speed, an Si atomic ratio of 2 at the boundary with the substrate and zero at the surface of a gate electrode 2 leads to the formation of an inverted taper type electrode in a directional gas ion etching method. Ion implantation that follows for the formation of a junction layer causes some ions implanted in the other side of the electrode 2 but the maximally densely diffused region does not reach the boundary surface of the electrode 2. Accordingly, the Schottky backward withstand voltage of an FET of this construction is higher than that of a conventional, normal taper type, and operational stability is enhanced.

Title: Poling system in ring type network
Inventor: KINUGASA TAKASHI
Filed: 1987-03-19
Abstract: PURPOSE:To effectively and rapidly execute poling by transmitting a command frame as it is without changing the command frame to a next station if a fault occurs in a station and transmitting it to the next station with changing an address part to the address of the station lower than its own station in the case of a normal state. CONSTITUTION:A frame reception part 11 which receives a poling command passes the signal as it is through a frame transmission part 18 and transmits it to the next station by a bypass process part 17' if the fault occurs in its own secondary station 10. If the fault does not occur, the address part of the poling data is altered to the address for the next station in an address rewriting part 15' so as to be transmitted to the next station by the frame transmission part 18 after checking whether the command is for its own station or not in a transmission address discrimination part 13'. Therefore, a primary station checks the address part of the poling data which returns after passing around and it detects that all secondary station is normal if the address part is for the primary station and also detects that the secondary station shown by the address is abnormal if it is not for its own station.

Abstract: PURPOSE:To constitute easily a processor in response to the number of programs which are processed in parallel in time division mode by giving no change to the bit length of a register selection command field. CONSTITUTION:When a microprogram muPA is executed, the arithmetic result of an arithmetic circuit 32 is stored again to a register in a register group 36 as long as a designated arithmetic processing register exists in the group 36. If a register used for operation is set within a register group 34, the arithmetic result of the circuit 32 is stored again to a register in the group 34. When a microporgram muPB is executed, the arithmetic result of the circuit 32 is stored again to a resister in a register group 38 as long as the designated arithmetic register is within the group 36. The said arithmetic result is stored again to a register in the group 34 if the register used for operation is within the group 34. The codes of these register selection fields are used in common with each other. Thus no change is required to the bit length of the register selection field despite a change in the number of programs which are processed in parallel.
