Abstract: On each sampling time, the data is inputted from the servo to the data input terminal(1) and the 1st latch(10) latches onto the current position of the motor. The latched value is read five times repeatedly by the CPU(50) to find out the data with the same value, and the Pn is calculated with the data which is through such a procedure as this. Furthermore, the pn-1 that is the difference between pn-1 and pn-2 is calculated and if the motor rotated once is firstly checked. In case the motor didn't make a rotation, Pn is calculated and checks that this pn value is less than 256 pulse. In case the condition Pn is under 256is satisfied, Pn is considered as the present position.

Title: Pyridoneisoxazol cephem compounds and their preparing processes
Inventor: CHANG MUN-HO
IPC: A61K31/545
Filed: 1992-07-15
Granted: 1995-07-27
Abstract: This is new cephalosphorin compd. and its parmaceutically acceptable salt of formula(I). In formula, R1 is H, or trityl, tert-butoxycarbonyl, or formyl; R2 hydrogen, p-methoxybenzyl, diphenylmethyl, or salting compd. such as Na or K; R3 and R4 are same or different, and H, p-methoxybenzyl or diphenylmethyl; and Q hydrogen, chloro, vinyl, acetoxymethyl, halomethyl, N- ethylpyridiniumylthiomethyl, N- carboxymethyl pyridiniumyl thiomethyl, and N- methyl- tetrazolyl thiomethyl gp. This cephem compd. manufacturing method comprises A) condensing the amine compd. of (VIII) with ketone of (VII) and producing the compd of (II); and B) acylating the aminothiazol compd of (II) with cephalosphorin of (III). This cephem compd. has good antibacterial activity.

Title: Burn-in enable circuit and burn-in test method of semiconductor memory device
Inventor: CHOE YUN-HO
IPC: G06F11/22
Filed: 1992-07-31
Granted: 1995-03-29
Abstract: The circuit provides a function for an efficient and reliable burn-in test for detecting the failures of DRAM during the device production process. A voltage detecting circuit detects a high voltage applied to a specific pin beyond the external voltage and generates a burn-in ebable signal. Then, the first and second word lines are enabled according to a low address synchronously inputted with a low address strobe signal(RAS) and the burn-in enable signal. When the specific pin becomes a voltage below the external voltage, the burn-in signal becomes disabled and the first and second word lines are disabled accroding to the burn-in signal.

Title: Tap package
Inventor: YUN JONG-SANG
IPC: H01L23/48
Filed: 1992-08-11
Granted: 1995-04-20
Abstract: The tab (tape automated bonding) package is characterized by the structure comprising: a sprocket hole fomed on both sides of a base film at predetermined intervals; a metal wire consisting of inner lead wires connected to a semiconductor chip on the base film and of outer lead wires connected to outside; device holes formed on a tape carrier by removing the base film so as to expose the ends of the inner lead wires; a semiconductor chip formed in the tape carrier; and at least more than one slit formed by removing the predetermined part of the base film between the outer lead wires and the device holes so as to expose the metal wires.
