    Abstract: PROBLEM TO BE SOLVED: To provide a process for producing a buried thin film resistor of a printed board. SOLUTION: A resistor layer is formed in a printed board having a conductive circuit in order to save the space for arranging a resistor in the board thus reducing the size of the board. Capacitance effect of pins at the opposite ends of a traditional resistor is reduced in order to enhance the speed and quality of signal transmission. It can be completed by a traditional production facility of printed board without purchasing a new facility and has advantages of mass production and reduction in production cost.

    Abstract: A memory module (20, Fig 3) contains a memory checker 50, which comprises a parity checker 51, a single bit storage 52 and a parity generator 53. Parity bits of incoming data are not stored, and parity bits for outgoing data are generated from the data by parity generator 53. If the parity bit of an incoming data byte is incorrect, the bit in storage 52 is set, whereby the calculated parity bit for the next outgoing byte is deliberately made incorrect; this causes an external parity checker (40) to generate a parity error interrupt (43).

    Abstract: A parity bit memory simulator including a parity bit memory formed of a single bit memory of fixed address length, which replaces the single bit parity RAM of variable address length of conventional memory module, and connected with its address signal line to the data bus of the memory module so that the parity bit memory provides and store parity bits for the computer system without changing the circuit layout of the data memory or caring about the capacity of the memory module. A voltage level detector and a refreshing operation detector can be installed in the parity bit memory to improve the error detecting function of the dynamic random access memory module in the parity bit system.

    Abstract: A method for fabricating the embedded thin film resistors of a printed circuit board is provided. The embedded thin film resistors are formed using a resistor layer built in the printed circuit board. Compared with conventional discrete resistors, embedded thin film resistors contribute to a smaller printed circuit board as the space for installing conventional resistors is saved, and better signal transmission speed and quality as the capacitive reactance effect caused by two connectors of the conventional resistors is avoided. The method for fabricating the embedded thin film resistors provided by the invention can be conducted using the process and equipment for conventional printed circuit boards and thereby saving the investment on new types of equipment. The method can be applied in the mass production of printed circuit boards and thereby reduce the manufacturing cost significantly.
