Title: Control valve assembly apparatus
Inventor: YOSHIDA KUNIHIKO
IPC: F15B13/00
Filed: 1983-05-27
Granted: 1985-06-15
Abstract: The control valve assembly is suitable for oil control in hydraulic construction machinery. It has logic valve pairs connecting to common oil supply lines in a single housing to simplify piping connectins. A 1st pair of parallel dead-end oil passages at one end of a housing block are fed by a 1st pump. A 1st logic valve has a pump port and a pilot signal port with axes normal to the line of the oil passages. The pump port communicates with one oil passage. Ths axis of the valve work port is normal to both the pump port and the oil passage axes. The other oil passage connects to a 2nd valve forming a pair with the 1st valve. Other identical valve pairs also connect to the oil passages.

Title: Arrangement for starting motor
Inventor: KIM IN-SOK
IPC: H02H7/08
Filed: 1983-07-09
Granted: 1987-02-11
Abstract: An electronic relay for starting single phase motor, which also does its function as an auto-recoverble breaker for overload. The electronic relay consisting of the triac(TC2), CT, R8, and R11, starts the single phase induction motor as the phase difference takes place between I1 and I2 by the triggering of the TC2. And abrupt increasing of I1 switchs off the triac(TC1) and recovers in accordance with the time constant fixed by R4 and C2.

Title: Information carrier
Inventor: SEDEREL WILLEM L
IPC: G11B7/258
Filed: 1984-07-26
Granted: 1992-06-05
Abstract: @ The invention relates to information carriers for optically readable information. The information carrier is built up from an actual carrier and a metal layer provided thereon. The actual carrier is manufactured from a polycarbonate resin consisting of a mixture of an aromatic polycarbonate, an epoxy compound and usual additives. The presence of an epoxy compound in the polycarbonate resin results in a better bonding between the metal layer and the polycarbonate resin. In order to be able to manufacture the actual carrier by means of injection molding, it is to be preferred to use a polycarbonate having a weight-averaged molecular weight from 10,000 to 20,000.

Granted: 1990-01-19
Abstract: A matrix of keys is polled by a CPU and is coupled to a decorder that accesses its columns.  The key values are defined by data stored in a ROM module.  The CPU has a RAM to store key values that are flagged. In high speed operation of the keys, situations can arise when more than three keys are simulataneously operated.  In order to minimise the possibility of false data being generated, a check routine is execulated to determine valid conditions.

Title: Battery feeding circuit for exchanges
Inventor: GAWAMI SIGERU
IPC: H04M15/00
Filed: 1985-12-27
Granted: 1990-04-28
Abstract: A reference resistance is connected to each of the two inputs.  AC and DC feedback are fed back to the two inputs with coupling capacitors via reference resistors and provide a desired AC terminating resistance and DC input resistance.  A control signal reverses the polarity of signals to the inputs by a noiseless signal to the DC feedback.  The AC signal on the input is differentially amplified so that the differential signal is distinguished from the unwanted common mode signal.  The terminating resistance for each signal can be changed by altering the feedback ratios of the feeding resistor between both signals.

Title: Anthracycline immunoconjugates having a novel linker and method for their production
Inventor: GREENFIELD ROBERT S
IPC: A61K47/48
Filed: 1989-02-10
Granted: 1996-11-13
Abstract: The present invention relates to novel immunoconjugates, methods for their production, pharmaceutical compositions and method for delivering cytotoxic anthracyclines to a selected population of cells desired to be eliminated. More particularly, the invention relates to immunoconjugates comprised of an antibody reactive with a selected cell population, having a number of anthracycline molecules linked to its structure. Each anthracycline molecule, having a keto group at the C-13 position, is conjugated to the antibody via a linker arm and is bound to that linker arm via an acid-sensitive acylhydrazone bond at the 13-keto position of the anthracycline. The immunoconjugates and methods of the invention are useful in antibody-mediated drug delivery systems for the preferential killing of a selected cell population in the treatment of diseases such as cancers and other tumors, non-cytocidal viral or other pathogenic infections, and autoimmune disorders.

Inventor: ERRANI DEO
IPC: E05B27/00
Filed: 1990-09-06
Granted: 1998-06-15
Abstract: The cylinder lock and key comprises at least two auxiliary pins (10,11) which are arranged or opposite sides with respect to the key slot (4) and have an end which protrudes into the slot (4). The opposite ends of the two auxiliary pins (10,11) cooperate with respective auxiliary tumbler pins (25,26) which are actuated by springs (27,28) and are suitable for being actuated in the position for rotation of the plug (3) by a lever (17) articulated in an opening (18) of the shank of the key (5) when the key (5) is fully inserted in the lock.

Title: Polishing method of wafer surface
Inventor: LEE JAE-HO
IPC: H01L21/304
Filed: 1990-10-12
Granted: 1993-04-24
Abstract: A method for grinding a wafer surface is composed of grinding a surface of the wafer by maintaining the pressure to the grinding surface plate so as not to apply the pressure on the surface of wafer directly through the abrasive, by floating the abrasive in the foams, which are generated during rotation with injection of grinding solution generating the foams between the wafer and grinding surface plate. The grinding solution is deionized water and the abrasive is alumina (Al2O3) with 1 m size. The ratio of the abrasive to grinding solution is 1:10 and the pressure is 0.05-0.2 kg/cm2. The rate of the grinding surface plate is 10-50 rpm.

Title: Motion detecting circuit and method of picture image signal
Inventor: KWAK MAL-SOP
IPC: H04N9/78
Filed: 1990-12-22
Granted: 1993-09-23
Abstract: The circuit and the method simplifies the  detection  process of brightness and color signal component separated from  composite image signal, separates the brightness signal and color signal  by filtering the image signal, eliminates interframe phase difference by reverting the phase of reverse color signal to frame unit using the vertical synchronization, and  detects  the  time  changes  of image signal by adding the color signal and brightness signal.
