Title: Ammonia analyzer
Inventor: MIKI HIDEYUKI
IPC: G01N1/00
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To enhance the measuring accuracy of an NH3 analyzer used in the measurement of the concn. of NH3 in the exhaust gas of a flue pipe. SOLUTION: The exhaust gas in a flue pipe is taken in a sampling pipe 1 from an exhaust gas suction pipe 1a through a bag filter 7. The dust in the exhaust gas is removed by the bag filter 7 and, since the bag filter 7 is exposed to the exhaust gas flow in the flue pipe, it flutters and the dust bonded to the bag filter 7 is shaken off. Since the temp. in the sampling pipe 1 is held to 300 deg.C by a heater 3, the adhesion and accumulation of ammonium hydrogen- sulfate due to the slight dust contained in the exhaust gas passed through the bag filter 7 can be prevented.

IPC: H01G13/00
Filed: 1989-07-12
Abstract: PURPOSE: To facilitate the soldering of an electric wire to the component at low cost by perfectly positioned soldering by a method wherein premolded solder is provided on the end part of the electric wire to be soldered to the component. CONSTITUTION: As a copper wire 2 is wrinkled in the sheath of solder 6, it is not slipped to the direction of wire, and it does not rotate by impressed parts 4 and 5. The non-deformed part 8 of the wire 2 is left between the impressed parts, premolded solder is intruded into the impressed parts 4 and 5 by deformation, and the part 8 is caught on the parts 9 and 10 without covering the outer surface 11 of the non-deformed part 8 of the wire. As the premolded solder 6 is longer than the wire part deformed by the impressed parts 4 and 5, the premolded-solder 6 has an omega-shaped cross section provided with two fins 12 and 13 in the plane surface of the matrix 14 of the wire 2. As a result, the adhesion of solder can be limited to a local part, and the quantity of solder can be adjusted properly.

Title: Method of controlling stroke number of reciprocating pump and device therefor
Inventor: YAMADA NOBUHIKO
IPC: F04B49/06
Filed: 1983-09-28
Abstract: PURPOSE:To make it possible to control the stroke number of a reciprocating pump by a constant speed motor without using a variable speed pump, by intermitting supply power at every stroke of the reciprocating pump to control the number of the intermission. CONSTITUTION:Upon filling of, for example, a medical liquid into a fluid pipe 8 by a reciprocating pump in accordance with the flow rate of the pipe 8, a flow rate transmitter 9 or another means delivers a pulse corresponding to a required amount of the liquid so that current from a power source 4 for supply power for a controller 3 is pulse-modulated by a converter 5. The thus obtained one pulse operates a constant speed motor 1 by one stroke by means of an output section 6. Due to the inertia of the pump the pulse is made shorter than the time period of this one stroke in such a way that current is cut off with the entire discharge stroke and a slight part of the suction stroke being left behind, thereby the remaining suction stroke is completed by the internal inertia and spring-back action of the pump.

Title: Pressure control method
Inventor: KIMURA JIYUN
IPC: F04D15/00
Filed: 1981-11-12
Abstract: PURPOSE:To prevent the idling even when there is no supply of the liquid, by monitoring the flow between a pressurizing pump and a liquid feeder/receiver then controlling said pump such that said flow will come within the predetermined range. CONSTITUTION:The pressure P and the flow Q in a piping 15 in front of a liquid feeder/receiver 16 are same with those in a pressure monitor system if the pump is not pressurized but varies on a curve 27, and under the latching state P and Q will move on the curve 21 to the right upon opening of a flow regulation valve 17 then a pressurizing pump 9 will start at the point A' while when P and Q move over the curve 43 to reach to the point B', it will move over the curve 22 upon the opening/closing of the valve 17 while when the valve 17 is reduced to reach to the point C' the pressurizing pump 9 will stop to reach to the point D' and when reaching to the point C' where Q is decreased to the setting flow 42 said pump 9 will stop, thereby it will move over the pressure loss curve 46 to reach to the point D' thus to control the pressure drop normally. When the liquid feed capacity in the conduit will deteriorate (For example the curve 49.), the flow will increase only to the cross point 50 even if the valve 17 is fully open thereby the pump will never function.

Title: Input circuit of microprocessor
Inventor: SAKURADA NOBUAKI
IPC: G06F3/00
Filed: 1981-11-13
Abstract: PURPOSE:To minimize the power consumption regardless of the ON/OFF of a switch, etc. of an input circuit, by pulling up or down an input terminal only in a period of the executing cycle of a microprocessor. CONSTITUTION:A switch pull-up controlling circuit 6 receives the signal of a control circuit 7 of a microprocessor and applies the signal to pull up an input terminal 10. The output signal of a buffer 8 is set at a high level only when the waveform of the switch pull-up is set at a high level. Thus the terminal 10 is pulled up via a current limiting resistance 9. In this case, the signal of a high level and the signal of a low level are fed to an inverter 4 when a switch 1 is opened and closed, respectively. A switch input circuit 5 decides a high or low level. The output signal of the buffer 8 is always set at a low level when no switch sense instruction is given. Thus no electric power is consumed regardless of the state of the switch 1.
