Title: Rotary engine
Inventor: CHOE EUI-HAK
IPC: F02B53/00
Filed: 1990-08-10
Granted: 1996-09-30
Abstract: The rotary engine installs eccentrically a rotary shaft, and a fan reciprocating within a rotor closely in contact with a cylinder. The engine rotates the fan by an explosion power of the fuel. The apparatus comprises: a cylinder(10) formed by two semi cylinders and including an intake hole(11) and a discharge hole(12); the rotor(2) having the eccentrically installed shaft and a hole(21) formed in a diameter direction in center; the fan(20) reciprocating along the hole(21). It can obtain a large power by elongating the length from the center of the rotor to the fan.

Title: Redialing method in pabx
Inventor: PARK TAE-KUN
IPC: H04M3/42
Filed: 1990-11-22
Granted: 1993-05-19
Abstract: The method improves the efficiency of  station  communication by switching the  station  communication  when  calling  the  busy station subscriber. The station communication  channel  is  formed when the called station is not in busy state after  analyzing  the dialing signal generated from the calling station. When the called station is busy, a check is made on whether the  redialing  signal is received or not within a fixed time. In  absence  of  redialing signal, the busy tone  is  released  and  the  hook  on  state  is serviced. When  the  redialing  signal  is  received,  the  called station number changes, followed by returning to the first step.

Abstract: PURPOSE: A video output disconnection apparatus of a monitor is provided to decrease time required for returning to a normal screen from the time when a screen saver mode of a computer is ended. CONSTITUTION: An amplifier(22) amplifies the level of a video signal. An analog/digital converter(24) converts an amplified video signal into a digital signal and generates a video data. A memory(26) records and reads a video data of the unit of the frame at a certain period. An address generator(28) generates a recording/read address of the memory. A microprocessor(30) controls the operations of the address generator and the memory, compares the data(D1, D2) from the memory and generates a disconnection signal(S). A clock signal generator(32) generates clock signals needed for the analog/digital converter, the address generator and the microprocessor. A deflection unit(34) controls an output of the deflection signal based on the disconnection signal. A mode setting unit(36) sets an operation state and reset state of the video process apparatus.

The dehorner includes a gas pipe(4) inside of the main body of a handle(1), a gas burner pipe(17), an iron(23), a supporting tube, a gas tank, an igniter and a gas exhaust(31). The iron(23) is located at the end of the gas burner pipe to be heated quickly. The inlet of the gas pipe(4) is opened by opening the valve(7) and pulling the supporting tube when the gas tank is installed. The flame is ignited at the ignition pore(25) by using a lighter or a match. The igniter is closed by releasing the supporting tube. The smoke generated in the dehorning process is discharged through the exhaust(31).

Title: Releasable plug-in connector
Inventor: ERMINIO MORETTI
IPC: F16L37/133
Filed: 1993-11-20
Granted: 1999-01-15
Abstract: A releasable plug-in connector for receiving a tubular plug-in part having a peripheral retaining rib. The plug-in connector consists of a housing having a cylindrical receiving space for receiving the plug-in part, and a separate securing ring made from a hard/resilient plastic material. The ring has retaining edges directed inwardly in the form of an arc of a circle that are pushed apart as the plug-in part is pushed into the connector and that then spring back elastically and engage behind the retaining rib after the plug-in part has been pushed in to lock the part in the connector. The retaining edges are connected to one another at their ends by a pair of V-shaped spring webs that are accessible from the outside of the housing so that they can be pushed into an unlocked position permitting the part to be pulled out of the connector.

Title: Position control apparatus for cursor
Inventor: PARK JOONG-JE
IPC: G06F3/0354
Filed: 1993-12-28
Granted: 1996-06-28
Abstract: The apparatus controls the position coordinate of the speed-variable cursor displayed on a monitor in a computer system. The apparatus comprises: a manipulator(2) rotatably exposed on a main body(1) to change the position coordinate of the cursor; one signal generator(8) generating signals on the position coordinate of the cursor in an up/down direction according to the up/down movement of the manipulators(2); the other signal generator(17) generating signals on the position coordinate of the cursor in an left/right direction according to the left/right movement of the manipulators(2); a support bracket(15), fixed to a base member(14) and supplying a revolving point for the signal generators(8,17).
