Patent KR-900004448-B1 (KR)
Title: Switching power supply
Inventor: YAMATO IKUO
IPC: H05B6/68
Filed: 1987-03-23
Granted: 1990-06-25
Abstract: The power supply has an AC source (1) connected to a rectifier circuit (2) the DC output of which is applied to an elecric power conversion circuit (3). The AC output of the converter is applied to the transformer (4) feeding a second rectifier circuit (5) supplying DC power to the magnetron (6). A temp. sensor (7) detects the temp. (T) of the magnetron and providing this remains below a preset value (Ts), an output power instruction value (P) is applied to the power conversion circuit by the control circuit (8). If the magnetron temp. exceeds, the preset value, the output power instruction is reduced to a lower value (Ps) and the magnetron overheating is relieved.

Title: Automatic clamping unit for receiving and holding a tool holder
Inventor: ERICKSON ROBERT A
IPC: B23B31/26
Filed: 1989-08-22
Granted: 1993-07-16
Abstract: The present invention relates to an automatic clamping unit of the type having a spring loaded lock rod that is movable between an unlocked and locked position. A pair of locking balls are confined about the locking rod and are operative to move outwardly for engagement with the shank of a tool holder in response to the locking rod moving from the unlocked position to the locked position. The lock rod of the present invention includes a variable sloped ramp for engagement with each locking ball. As each locking ball moves along the variable sloped locking ramp, the mechanical advantage applied to the locking balls through the ramp varies due to the variation in slope. Each locking ramp is particularly configured such that the resultant locking load exerted by the locking balls against the shank of the tool holder is relatively constant although the position of the locking rod and the force being applied to the locking rod varies.

Abstract: The fiber  is  made  by  blending  2-30  wt.%  of  the  block polyetherester antistatic agent, containing  10-60  wt.%  (against the whole acid  component)  of  polyethylene  oxide  of  molecular weight of 600-6000, 0.01-5 wt.% of anhydrous trimellitic acid, and 2- 20 wt.% of the metal salt compound of sulfonic acid, whose  main repeat unit is ethylene terephthalic acid, and  melt-viscosity  is larger than 0.75 times that of the  regular  polyester,  with  the regular polyester. The fiber has good colour  and  workability  as well as antistatic property by  increasing  melt-viscosity,  while overcoming yellowing phenomenon.

Abstract: An apparatus for displaying an image title is disclosed. The apparatus comprises: a first converting unit(204) for converting an analog signal from an image signal processor to a digital signal; a comparator(205) for comparing the output signal from the first converting unit(204) to a reference value of various chrominance signal inputted from an external; a first memory(206) for storing the output from the comparator(205); a second memory(210) for storing an external information so as to control the data stored at the first memory(206); a second converting unit(209) for converting the data stored at the first memory(206) according to the control signal based on the information stored at the second memory(206); a memory controller(207) for providing the control signal so as to control the first memory(206); a controller (208) for controlling the comparator(205) and the second memory(210) and a display unit(212) for displaying the information inputted through an information input unit. Thereby, a number of title recording can be established.

Granted: 1996-05-01
Abstract: The manufacturing method of polyester includes steps of : (a) estertificating terephthalic acid or its ester forming derivatives and isophthalic acid or its ester forming derivatives by using diol compound, whose main constituents are side chain forming agent with multi functional group and ethylene glycol; (b) polymerizing with carbonate compound, which is added during the time between from 20 min. after reaction is initiated to before 10 min. of reaction termination, by using catalyst and thermal stabilizer.

Abstract: PCT No. PCT/EP90/01525 Sec. 371 Date May 23, 1991 Sec. 102(e) Date May 23, 1991 PCT Filed Sep. 10, 1990 PCT Pub. No. WO91/03897 PCT Pub. Date Mar. 21, 1991.A process is disclosed whereby each of a plurality of stations, transmitting messages segmented into multiple sequential packets, is able to access a transmission channel of a local communications network. A residual packet number is associated with each message representing the number of packets remaining in the message after the instant packet has been transmitted. The number of packet collisions on the transmission channel is reduced by employing a resolution phase, which may be divided into several time intervals. Stations transmit messages with certain residual packet numbers during predetermined time intervals of the resolution phase. A station transmits its next packet after the end of the ongoing transmission if its residual packet number is smaller than the residual packet number of the ongoing message transmission.
