Title: Method for controlling data trasmitting
Inventor: HONMA SIGEO
IPC: G11B20/10
Filed: 1986-09-10
Granted: 1990-08-28
Abstract: A magnetic disc controller unit system is designed to provide high data transfer rates between a disc drive and a computer system. The disc controller (42) is coupled between the disc drive and the port of a CPU (2). The controller is microprocessor based and controls the channel interface with (41), a control interface unit (43) and a data buffer (44). The operating cycle begins with a location instruction to position the read head. Data are transferred into a buffer memory that serves the control unit. An interrupt is generated when the transmission rate of data from the disc to the buffer exceeds that of the buffer to the CPU.

     본 발명은 상기와 같은 문제점을 해결할 수 있도록 클록 오류검출선택회로에 의해 감시클록이 피감시클록주기의 2배이상인지 미만인지를 선별할 수 있게 하고, 또한 클록 오류검출회로에 의해 감시클록이 피감시클록주기의 2배보다 작을경우 클록오류를 검출할 수 있도록 클록오류 검출 및 선택회로를 제공하는 것이다.

IPC: C21C5/28

Abstract: PCT No. PCT/AU90/00233 Sec. 371 Date Sep. 26, 1991 Sec. 102(e) Date Sep. 26, 1991 PCT Filed May 30, 1990 PCT Pub. No. WO90/15165 PCT Pub. Date Dec. 13, 1990.The specification discloses a process for producing a ferroalloy in a smelting vessel. A material containing an alloying metal is injected into a molten bath contained in the vessel. A flux, a carbonaceous material and an oxygen-containing gas are also injected into the vessel. A gas which may be the oxygen-containing gas is injected into the molten bath in order to stir it. The rates of injection of the various components are controlled to achieve control of the oxidizing and reducing environment within the vessel consistent with a rapid rate of injection. The material containing the alloying metal is either reduced and incorporated into the metal phase or oxidized and incorporated into the slag. Combustion gases above the molten bath are oxidized to provide further heat to the process. Alloyed metal or slag containing the alloying metal are recovered as product. The process is applicable to the production of ferroalloys such as ferrochromium, ferromanganese, ferronickel and ferrovanadium.

Title: Protecting circuit for write enable(we) buffer
Inventor: KIM JONG-PHIL
IPC: G11C7/22
Filed: 1992-07-04
Granted: 1995-09-07
Abstract: The circuit protects the write enable buffer(10) from a noise generated from a data output buffer(50) during the data write operation in a memory device having a number of input/output pads. The circuit, which is incorporated between the write enable buffer(10) and the internal write clock generator(30), couples the write enable buffer(10) to the internal clock generator(30) during the data write step, separates them during the data read step, and reconnects the write enable buffer(10) to the internal clock generator(30) in preparation of the next write cycle while the latter is coupled to the write enable buffer protection circuit to transmit an internal write clock signal.
