Abstract: The apparatus permits the approach of a room temp. to a set temp. upon dehumidifying operation and stabilizes the room temp.. A humidity is controlled by a room humidity detected by a humidity sensor(66), and a set humidity set in a humidity setter(68), only when the room temp. detected by a room temp. sensor(65), is in a set temp. zone enclosed by a first reference temp higher than a set temp. and a second reference temp. lower than the set temp.. When the room humidity is increased to a value higher than the set humidity, the dehumidifying capacity of a refrigerant evaporator as well as the heating capacity of a hot water type heater are increased by one rank. When the room humidity is lower than the set humidity, the dehumidifying capacity of the refrigerant evaporator and the heating capacity of the hot water type heater are reduced by one rank to approach the room humidity to the set humidity without keeping the room temp. away from the set temp..

Abstract: CMOS 구동기는 단일한 저항으로 인해서, 조절가능하게 "빠른 오프-느린 온"의 전이를 행하고 상기 구동기가 스테이트 전환을 하는 동안에 동시에 온되지 않는, 출력소자들을 갖도록 허용된다. 상기 구동기의 출력 및 전원 전류들은 감소된 조파들을 포함한다. 상기한 저항은 출력단 PMOS-NMOS 소자들의 게이트들에 연결되며, 게이트들에서의 내부 커패시턴스와 함께 RC 회로를 형성하여서 게이트 구동전압들의 턴온전이를 연장시킨다. 각각의 출력소자는 그러면 비교적 느리게 턴온되고, 반면 정상적으로 턴오프된다. 출력전류 전이시간들은 기본적으로 상기 저항 및 내부 커패시턴스에 의해 결정된다. 상기 저항은 폴리실리콘 또는 확산을 이용하여 구현되며, 되도록이면 출력단을 구동하는 입력 PMOS 및 NMOS 소자들의 온-채널 저항의 10배 크기를 가짐이 바람직하다. 상기 저항 및 내부 커패시턴스들은 본질적으로 온도 및 전원 전압에 독립적이며, 반면 공정에 약간의 의존성을 나타내므로, 전류출력 전이시간들은 CMOS 파라미터의 편차에도 불구하고 조정이 가능하다. 
     CMOS 버퍼의 3-스테이트 실시예는, 인에이블 신호가 하이일때 개폐적으로 양출력 게이트들 간에 저항이 연결되는, 병렬로 연결된 PMOS-NMOS 소자들을 사용한다. 제1입력 PMOS 및 NMOS 소자들에 걸쳐 병렬로 연결된 제2입력 PMOS 및 NMOS 소자들은 인에이블 신호가 로우일때 제1입력 소자들을 지나 턴온된다. 로우의 인에이블 신호가 상기 저항을 분리해내고 양출력 PMOS 및 NMOS 소자들을 턴오프시키는 반면, 하이의 인에이블 신호는 상기 구동기 회로를 인에이블시켜서 회로의 출력을 고 임피던스 상태로 만든다.

Abstract: Disclosed is a video printing apparatus.  The apparatus comprises a signal generator and a preheat controller.  The signal generator generates a line preheat synchronizing signal which has a predetermined time after a line synchronizing signal is generated.  The preheat controller preheats all heaters of a thermal transfer head(TPH) while the line preheat synchronizing signal is generated from the signal generator.  The non-linear characteristic at a low density period of the TPH is compensated to be linear.  Thereby,the print quality can be improved.

Abstract: PURPOSE: A digital/analog synchronous recorder/player is provided to record/play back digital signals and analog signals on the same tape by receiving broadcasting signals through a digital and an analog head mounted on a single head drum. CONSTITUTION: An analog modulator(1) encodes NTSC(National Television System Committee) analog signals(Ai) while a digital modulator(2) encodes digital signals(Di). Write amplifiers(3,4) amplify outputs(A1,D1) of the analog/digital modulators and write the amplified data(A2,D2) through heads(HA1/HA2,HD1/HD2). Read amplifiers(5,6) amplify tape data through the heads. A D/A decider(9) checks the outputs of the analog/digital modulators and outputs(A3,D3) of the heads to decide digital and analog signals. An analog demodulator(7) filters output(A4) of the read amplifier(5). A digital demodulator(8) filters and corrects an error of output(D4) of the read amplifier(6). A system controller(10) switches the heads by checking output(V1) of the D/A decider and controls writing/reading through rotation of a drum motor(11) and a capstan motor(12).

According to the invention, the system comprises an antenna (2) placed in the cabin of the locomotive, connected by radio waves with a multiple function transmitter (5) transmitting signals onboard to a radio receiver (6) fitting out the locomotive, said receiver (6) only receiving the commands of the transmitter (5) and permitting communication with the locomotive equipments and with an onboard computerized system (7) which processes the commands given by the receiving block (6), the communication between the receiving block (6) and the computerized system (7) being achieved by a CANopen communication network, the onboard computerized system (7) processing the commands by a software as it receives them and transmitting signals to the driving equipments of the locomotive provided with some transducers (A, B, C and D), as follows: to a Diesel engine (8), to a braking equipment (11), to the hydraulic transmission (9), to some bogie anti-skid and anti-blocking units (12/1 and 12/2), to a reverser (10), to some sanding units (14/1 and 14/2), to some ringing devices (13/1 and 13/2) and some automatic couplings (15/1 and 15/2) and, when by a command selection unit (3) there is selected a command for a control panel for local equipments, the command to the onboard computerized system (7) is achieved by means of a local control panel provided with two stick controllers (F and G) transmitting the commands by electric circuits to the onboard computerized system (7), the selection unit (3) having also the possibility of making the connection with a local control equipment.
