Patent JP-H07120452-A (JP)
Title: Selective separation method for cell
Inventor: INAMORI KAZUNORI
IPC: G01N33/53
Filed: 1993-10-21
Abstract: PURPOSE:To provide a method for peculiarly and efficiently separating only a specific cell. CONSTITUTION:This selective cell separation method consists of the following processes; a monoclonal antibody or a polyclonal antibody having binding quality with an antigen manifesting on the surface of an isolated cell, or protein or peptide containing an antibody fragment having such binding quality is bound with a compound containing an amino or imino group and having molecular weight equal to or less than 10000 (i.e., preparation of modified antibody). Then, blood, blood plasma, blood serum, body fluid or cell suspension is made to react and bound with the modified antibody. Cell sap bound with the modified antibody so prepared is treated in water insoluble carrier containing a carboxyl group on the surface. A target cell is thereby bound with a carrier, and other cells or substances are removed, thereby dissociating only the target cell from the carrier.

Title: Stabilizing device for suction pressure in suction device
Inventor: FUJITA EIJI
IPC: B60P1/60
Filed: 1988-10-19
Abstract: PURPOSE:To stabilize the suction pressure of a suction pressure source by laying bypass piping between the delivery side piping and the suction side piping of the suction pressure source, and simultaneously, detecting the pressure of a suction side, and controlling an opening closing valve according to this detected signal. CONSTITUTION:The bypass piping 9d is laid between the delivery side piping 9c and the suction side piping 9b of the suction pressure source 11, and simultaneously, the opening closing valve 13 is connected to the piping 9d, and the suction side pressure is detected by a detector 14. Since an opening closing instruction is outputted to the opening closing valve 13 so that the output value of the suction pressure source 11 is settled between a predetermined lower limit value and a predetermined upper limit value, when the valve 13 is opened, compressed air (clean air passed through a filter part 10) is returned to the suction side from the suction pressure source 11. Therefore, foreign matter is prevented from being mixed into the pressure source 11, and the returning of the compressed air to the suction side is better than the introducing of outside air. Besides, the response of the pressure control is good, and a noise caused by opening the valve 13 can be reduced as well.

Title: Power capacitance device
Inventor: OKAMURA MICHIO
IPC: H01G11/00
Filed: 1993-09-28
Abstract: PURPOSE:To detect a fault in a short time by a method wherein a constant voltage source and a light emitting diode are connected in series between the terminals of each capacitor cell and the fault in each capacitor cell is detected by the luminous of the light emitting diode. CONSTITUTION:A Zener diode D1, a light emitting diode D2 and a current limiting resistor R1 are connected in series between the terminals of a capacitor cell C.

A power capacitance device is composed of a number of the capacitor cells C which are arbitrary connected in series. If the terminal voltage of one of the capacitance cells C is dropped below the Zener voltage, the light emitting diode of that cell is extinguished. Therefore, the operation states of the respective capacitor cells C including their remaining charges can be monitored visually.

Filed: 1993-10-22
Abstract: PURPOSE:To prevent occurrence of writing drain disturbance at the time of writing a data by setting the threshold value under a state where a charge storage section is not charged between a threshold value under written state and a threshold value under erased state. CONSTITUTION:An electrically erasable nonvolatile memory, e.g. a flash EEPROM, is provided with a floating gate polysilicon (Poly) layer 5 on a silicon substrate 1.

Since this threshold level is between a threshold level under written state and a threshold level under erased state, the writing drain disturbance is lightened significantly.

Title: Psk signal demodulation system
Inventor: KOBAYASHI HIDEO
IPC: H04L27/22
Filed: 1987-10-22
Abstract: PURPOSE:To contrive the improvement of the communication efficiency of TDMA system by storing a burst signal as a digital value once entirely and applying demodulation by the digital arithmetic processing using high speed Fourier transformation method. CONSTITUTION:Two input buffers 11, 12 for sides A, B are connected to an input buffer changeover control circuit and the signal is at first stored in the input buffer 11 of the side A. In storing N-set of digital data by one burst to the input buffer 11 of the side A, the N sets of digital data are transferred to a digital processing demodulation circuit 13. While the storage data of the side A is being processed by the circuit 13, the next inputted burst signal is connected to the side B and stored by a changeover control circuit 10. Namely, the data stored in the side A is processed for a receiving time by one burst and outputted from an output terminal 1301 as the demodulation data. Thus, the input buffers are switched alternately for the sides A, B, then the TDMA signal is demodulated without intermission.

Title: Controlling method for temperature distribution
Inventor: OKUDA SHOJI
IPC: H01L21/31
Filed: 1990-10-03
Abstract: PURPOSE:To control the temperature distribution in a wafer by a method wherein a thermocouple is inserted in a plurality of regions of a wafer chuck, a thermoelectromotive force to correspond to a temperature difference, which is generated between the regions, is measured, the measured value of this force is fed back to the amount of energy to be supplied to each heater and the temperature control of the water is conducted. CONSTITUTION:A thermocouple 2 for differential heat analysis use and motors 3 and 4 are buried in an electrostatic chuck, a thermoelectromotive force, which is generated by a temperature difference between the temperatures of the central part and the peripheral part of the chuck, is found and the value of this force is fed back to the service voltage of each heater. In the case the temperature distributions in the chuck 1 and a wafer are similar to each other, the temperature control of the wafer is conducted by raising the temperature of the peripheral part of the wafer. In the case the temperature distributions in the chuck 1 and the water are not similar to each other, the temperature distribution in the chuck 1 is subjected to temperature control in such a way that the temperature distribution in the central part of the chuck 1 is reduced when the temperature distribution in the wafer is even. As the temperature distribution in the wafer in plasma can not be normally measured accurately, a film formation is executed while the temperature control is conducted like the above and the most proper film-forming conditions can be found.

Title: Transmission line code error monitoring system
Inventor: RIKIYAMA HIROKI
IPC: H04L7/00
Filed: 1988-10-21
Abstract: PURPOSE:To obviate a descrambling circuit in a repeater by synchronizing the resetting period of an M system generating circuit to an error monitoring section period and further, selecting the resetting period so that the M system generating circuit can be reset at the even number of times in one error monitoring section. CONSTITUTION:After an information signal is inputted from an input terminal 1 and parity-counted by a parity counting circuit 2, the exclusive OR is obtained in a pseudo random signal generated by an M system generating circuit 3 and an exclusive OR circuit 5 and scrambling is applied. Thereafter, the parity bit is added by a parity bit adding circuit 6 and outputted from an output terminal 7. By the resetting pulse generated periodically by a resetting timing generating circuit 4, the M system generating circuit 3 is reset for (m) bits; the parity counting circuit is reset for 2m bits and the parity counting is executed for 2m bits. Thus, in the repeater, when the transmission line code error monitoring is performed, a descrambling circuit is made unnecessary.
