Title: Apparatus and method for preventing unauthorized access to bios to bios in a personal computer system
Inventor: BEALKOWSKI RICHARD
IPC: G06F21/12
Filed: 1990-08-11
Granted: 1993-06-10
Abstract: An apparatus and method for protecting BIOS stored on a direct access storage device (62) into a personal computer system (10). The personal computer system (JO) comprises a system processor (26), a system planar (24), a random access main memory (32), a read only memory (36), a protection means and at least one direct access storage device (62). The read only memory (36) includes a first portion of BIOS and data representing the type of system processor (26) and system planar (24) I/O configuration. The first portion of BIOS initializes the system (10) and the direct access storage device (62), and resets the protection means in order to read in a master boot record into the random access memory (32) from a protectable partition on the direct access storage device (62). The master boot record includes a data segment and an executable code segment. The data segment includes data representing system hardware and a system configuration which is supported by the master boot record. The first BIOS portion confirms the master boot record is compatible with the system hardware by verifying that the data from the data segment of the master boot record agrees with the system processor (26), system planar (24), and planar (24) I/O configuration. If the master boot record is compatible with the system hardware, the first BIOS portion vectors the system processor (26) to execute the executable code segment of the master boot record. The executable code segment confirms that the system configuration has not changed and loads in the remaining BIOS portion from the same protectable partition on the direct access storage device (62) into random access memory (32). The executable code segment then verifies the authenticity of the remaining BIOS portion and vectors the system processor (26) to begin executing the BIOS now in random access memory. BIOS, executing in random access memory (32), then activates the protection means to prevent further access to the protectable partition. BIOS boots up the operating system to begin operation of the personal computer system.

Title: Working device of stone
Inventor: KWON CHOL-KWAN
IPC: B28D1/04
Filed: 1992-09-16
Granted: 1994-11-16
Abstract: The gang saw device diversifies and improves a working skill of the gang saw by varying a height and an angle of the saw and by a precise horizontal movement, etc. in the variable angle state. The device characterizes that a guide housing attached with a guide nut is set by a piercing setting of a guide rod; a pair of rails are set in the length direction of the center of base, on the rail a moving plate having a roller and a shaft being installed, on one side of the shaft a base cap being bearing-jointed; a first knuckle part having a hinge part variable in a vertical direction is formed on the upper of the base cap; and a second knuckle part having a hinge part variable in a horizontal direction is formed; and the knuckle parts are connected and fixed to a angle base.

Title: Drive sensor for vacuum cleaner
Inventor: LEE JANG-U
IPC: A47L9/28
Filed: 1992-09-22
Granted: 1995-03-10
Abstract: sensing a fluid velocity according to the space difference between an intake and a suction plane using a ultrasonic transmitting and receiving device; calculating flux by multiplying the fluid velocity by the section area of the fluid, calculating a suction work rate on the basis of the flux; backing the cleaner if it can not be rotated; turning the cleaner to the left if the cleaner can be rotated and then driving it; and completing cleaning.

Abstract: 한쌍의 회전 로울러사이에 기판을 투입함으로써 광섬유 기판의 표면을 마링하기 위한 방법 및 장치가 개시되어 있다. 로울러들중의 하나는 연마제로 코팅되어진다. 제2 로울러는 경질일 수도 있고 변형가능한 피복물을 가질수도 있다. 선택적으로, 로울러들중 하나 또는 둘 모두는 상기 기판에 리플 패턴을 주기 위해 톱니 형태로 가공되어질 수 있다. 로울러들 사이의 갭을 수동으로 및/또는 자동으로 조정하기 위해 수압, 공기압 또는 다른 장치가 이용되어질 수 있다. 로울러들중 하나 또는 둘 모두는 마링작용을 증진하기 위해 가열되어질수도 있다. 
     캠 메카니즘이 역시 닙내의 압력을 조정하기 위해 사용되어질 수 있다.
