Title: Process for producing heat pipe
Inventor: FUKUI YUICHIRO
IPC: C09K5/04
Filed: 1986-12-13
Granted: 1990-07-09
Abstract: Heat pipe comprising a steel container with water enclosed as working liquid is treated with an aq. vanadate soln. over the inner surface of the container to form a protective coating over the surface. The working liq. enclosed is prepared by adding an alkalinising pH adjusting agent to pure water, to give an adjusted pH of 8-12, pref. 8.5-10.5. The agent is selected from hydrazine, ammonia, and amine cpds., morpholine or triethanolamine; pref. addn. is hydrazine. The inner surface can be further treated after removal of the vanadate soln. with H peroxide in the form of a 0.1-34 wt.% aq. soln.. Evolution of H2 gas is prevented, avoiding deterioration of heat pipe performance.

Title: Electronic blood pressure meter
Inventor: MIYAWAKI YOSHINORI
IPC: A61B5/022
Filed: 1987-05-16
Granted: 1989-07-28
Abstract: The blood pressure meter has a cuff adapted to be fitted around the arm of a patient whose blood pressure is to be measured.  The cavity can be pressuirsed and depressurised by a pump.  The pressure is sensed in the cavity and representative output signals are produced. A pulse wave component in the output signal of the sensor is then detected.  The amplitude of the detected pulse wave is then determined.  The systolic and the diastolic blood pressures are then determined according to the determined amplitude and the output signal produced by the pressure  sensor.  Compensation is then performed relating to the systolic and diastolic blood pressures.

Title: Filter apparatus
Inventor: WOLF JOACHIM
IPC: B01D35/30
Filed: 1988-11-28
Granted: 1991-03-30
Abstract: A filter apparatus is equipped with easily releasable coupling ends (28) of the inlet and outlet connection pieces (27) respectively, and the top wall (11) carrying the inlet and outlet connection pieces is connected unreleasably to the adjoining peripheral wall of the filter housing. For maintenance or cleaning, the filter apparatus is exchanged as a self-contained unit. Since the filter housing itself is not separable in operational terms and there are therefore no sensitive separable seals between housing parts, the housing cross-section can be of any form and therefore especially cuboid for the most effective possible utilization of space.

Title: Microporous membranes having increased pore densities and process for making the same
Inventor: FISHER HAROLD M
IPC: C08J9/00
Filed: 1989-05-11
Granted: 1994-03-09
Abstract: Disclosed are a process for forming an open-celled microporous membrane (e.g., in film or fiber form) and a novel microporous membrane formed thereby. The process generally includes sequential cold and hot stretching operations, whereby the cold stretching operation is preferably accomplished in a plurality of discrete cold stretching steps. In this regard, the total cold stretch extension is of greater than about 30 percent, and advantageously greater than about 40 percent based upon the initial unstretched length of the nonporous precursor, with this total cold stretch ratio being distributed among a plurality of discrete cold stretching steps. The novel membranes of this invention are characterized by decreased pore sizes and increased pore densities. For example, the membranes of this invention will have an average pore radius as determined by mercury porosimetry of less than about .040 micron. The membranes of this invention, moreover, exhibit a distinctive "bluish" color hue (i.e., a Macbeth Coloreye TM  b* value of less than about -10 as determined by placing a single ply sample of the membrane against a black background).

IPC: H04N5/235
Filed: 1991-04-02
Granted: 1994-02-07
Abstract: The circuit detects a luminance signal from an image signal. The luminance signal is buffered and converted into a DC signal with a mean value level of the buffered luminance signal. A differential amplifier amplifies the level difference between the DC signal and a reference. A motor drive receives an the amplified signal, as a drive voltage signal, and a predetermined motor voltage signal, as a drive voltage signal of the opposite polarity. The difference between the drive voltage signals forms a motor drive voltage signal. An iris motor opens or closes the iris diaphragm in response to the motor drive voltage signal. A clipper connected between the signal converter output and the amplifier input, blocks the converter DC signal output when it exceeds a reference value and passes it when it is smaller than the reference.

Abstract: The apparatus for generating search control signal in artificial intellectual system comprises a detector for detecting the level of video signal, a synchronous signal detector for detecting synchronous signal from a demodulated video signal, a control detector for detecting video tape control signal, an AND gate for combining the output of the control detector logically to determine whether or not a program is recorded in the tape, a program recording detector for determining whether or not only control signal is recorded in tape, and an OR gate for outputting the search control signal in logical combination with outputs of the AND gate and the program recording detector. Thus this invention is for determining precisely whether or not a program is recorded in tape and playing non-programed part of the tape at high speed.

Title: Automatic searching method for tv receiver
Inventor: LEE SANG-YONG
IPC: H04N5/50
Filed: 1991-12-28
Granted: 1994-10-22
Abstract: The method provides automatic searching of broadcasting channel which can excute two-way seaching. The method comprises: the 1st step for searching the channel by controlling tunor, the 2nd step for checking the one signal between (AFT+) and (AFT-), the 3rd step for low speed searching, the 4th step for searching the other signal of the 2nd step, the 5th step for detecting the synchronous signal, the 6th step for continuing or quitting the search according to synchronous signal.

Title: Digital subscriber matching circuit
Inventor: NAM HONG-SUN
IPC: H04M11/00
Filed: 1991-12-30
Granted: 1994-08-31
Abstract: The circuit reduces dependency of a U-transceiver, and effctively supplies emergency power to a remote subscriber. The circuit includes an overvoltage protector (211) which suppresses overvoltage, a test access unit (213) which transfers a telephone line, a multitude of U-interface means (21), an ISDN exchanger power controller (IEPC:22), an extension PCM matching control means (28), an U-transceiver(213), an emergency power unit (214), a clock compensation means (32), an ISDN D channel exchange control means (24:IDEC), a memory unit (29), a common memory (30), a memory map decoding means (25), an interrupt processing means (26), a CPU (27), and a MMC port (32).
