Inventor: SAITO NOBUYUKI
IPC: H04B1/40
Filed: 1993-07-07
Abstract: PURPOSE:To simultaneously suppress plural disturbing waves by the small number of cancelers by adjusting at least one of the phase and level of a part of a transmitting wave led out from a transmitting cable and then injecting the adjusted wave into a receiving cable. CONSTITUTION:A part A (F1, F2,... Fn) of a transmitting signal is branched by a direction coupler 21 inserted into a transmitting cable 11, the phase of the signal is controlled by a variable voltage phase shifter 23 and its amplitude level is adjusted by a variable voltage attenuator 24 and supplied to a succeeding receiving side direction coupler 25. On the other hand, a transmitting wave B (f1, f2,... fn) is inputted to the coupler 25 through a receiving antenna 5. Then the phase shifter 23 and the attenuator 24 are controlled so as to mutually offset and cancel both the signals A (F1, F2,... Fn), B (f1, f2,... fn).

Title: Gas chromatograph
Inventor: SHIYOUJI MASANAO
IPC: G01N30/32
Filed: 1997-07-17
Abstract: PROBLEM TO BE SOLVED: To prevent the running out of an excessive quantity of sample from a pressure control valve by temporarily changing the control constant of the valve after a pressure drop is detected in a sample introducing section when the sample is injected into the introducing section from a gas syringe. SOLUTION: A gas chromatograph is provided with a control section 8 equipped with an analysis mode switch 9 and, when the switch 9 is turned on, the control section 8 monitors the occurrence of a pressure drop in a sampling introducing section 5 by means of a pressure sensor 5. When a sample is injected into the section 4 from a manual or automatic sample injector by using a gas syringe, etc., thereafter, the pressure in the section 4 temporarily drops and, upon detecting the pressure drop, the control section 8 changes the control constant of a pressure control valve 6 so that, in general, the valve 6 may slowly respond for a prescribed period of time. Since the valve 6 is gradually opened when the control constant is changed, the running out of an excessive quantity of sample from the valve 6 can be prevented.  After the prescribed period has elapsed, the control constant is returned to the previous value and the valve 6 becomes to respond quickly.

Abstract: PURPOSE: To exactly dispense a premetered unit does of liquid by providing the device with a first reservoir for containing the feed of liquid in a pressurized state, a manually operating member, a metering chamber of a second elastomer and a valve member and specifically moving this valve member. CONSTITUTION: A spray head actuator 14 is depressed to downwardly move a stem 50 to a position where the metering chamber 74 housed with the liquid of the dose of one unit is connected to the ambient by passages 90 and 92. The passage 90 extends transversely in the stem 50 and the passage 92 extends from the passage 90 to the top end of the stem 50 connected to the dispensing orifice 94 of a spray head 14. When the stem 50 is further moved downward, the passage closes the metering chamber 74 from the reservoir 15 and, on the other hand, the passage 90 moves into the metering chamber 74 and is communicated with the ambient.  As the metering chamber 74 opens to the ambient via the passages 90, 92 and the orifice 94, the pressure of the main reservoir 15 crushes the reservoir 72 and the contents of the metering chamber 74 are extruded to the ambient under the pressure of the main reservoir 15.

Title: Digital signal transmitter
Inventor: NAKAYA HIDEO
IPC: H04L7/04
Filed: 1981-11-30
Abstract: PURPOSE:To extract the V block synchronizing signal out of the reproduced signal in a simple and assured way, by inserting the specific series data as the synchronizing signal into the 1st block among the units comprising plural blocks of the digital signal. CONSTITUTION:The reproduced data is applied to a latch 19 via an adder 18, and the output delayed by a clock emerges out of the latch 19. Both the reproduced data and the output of the latch 19 are fed to a comparator 20 and to a comparator 23 via an adder 21 and a latch 22. The outputs of the comparators 20 and 23 are loaded to a counter 25 via an NAND gate 24. Therefore the data is loaded to the counter 25 only when the data of more than 3 samples increase one by one in a correct sequence. When the output of the counter 25 reaches the prescribed value, the output is produced from a comparator 27 to be set at 1. If this output is within the width of a window pulse WND, the V block synchronizing signal is produced. Thus the V block synchronizing signal can be extracted in a simple and assured way.
