Filed: 1985-04-24
Abstract: PURPOSE:To analyze organic acid in a liquid to be measured with a high sensitivity regardless of inorganic anions mixed, by employing a suppressor column filled with a cation exchange resin to detect electric conductivity after a cation exchange. CONSTITUTION:When a specimen sampling valve 5 is turned ON and the internal passage is switched over to the connection state as shown by the broken line from that as shown by the solid line, a liquid to be measured in a weighing 5g is carried on an elution liquid to columns 6 and 7. In the columns 6 and 7, organic acid is discriminated form inorganic anions in the liquid being measured while being separated chromatographically. The elution liquid of the column 7 is introduced to a suppressor column 8, where the elution liquid and organic ions undergo an ion exchange reaction while the passage thereof 8 lowers the electric conductivity of the elution liquid to 480mus/cm from 1,200mus/cm. Components subjected to such an ion exchange reaction are introduced to a detector 9 to detect the electric conductivity thereof and a chromatogram is drawn on a recorder or the like based on the resulting detection signals.

Title: Air removal pin
Inventor: OKAMURA NAOMI
IPC: B65D83/00
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To prevent as much as possible the circumferential surface of the inside of a body from being scratched, minimize the entry of moisture into a cartridge, and prevent contents from hardening, by making a slit longitudinally into the hanging plate of an air removal pin used when a plunger member is fitted into the cartridge filled with the contents. SOLUTION: When a plunger member 28 is pushed and fitted into the rear end of a cartridge K, an air removal gap L1 is made by the space of the slit 14 of an air removal pin 12. Air existing in the rear end of the cartridge K is removed out by the gap L1. At the time, the air removal pin 12 firmly pushes the internal wall of the body 20 of the cartridge. However, because both end faces of the air removal pin 12 are thin, the flexibility of the hanging plate 12b increases by the slit 14, and an angular end does not exist, a streak- groovelike scratch due to the air removal pin 12 is not made on the internal surface of the rear end of the body 20 of the cartridge. Therefore, moisture from outside is prevented from entering the cartridge.

IPC: H02M5/257
Filed: 1990-04-05
Abstract: PURPOSE:To start an inverter unit stably at all times by slightly shifting the operating points on a magnetization characteristic curve of core for each of three phases thereby imbalancing the three phases and establishing the phase order. CONSTITUTION:Number of turn of input side winding 4-1 corresponding to each of three phases of a frequency division transformer 4 excited by single- phase AC power outputted from a two-phase inverter 3 is increased or decreased by 2 or 3 ampere turns thus differentiating the magnetization characteristics of three-phase annular cores 4a-4c by 2-4%. Since the operating points of three- phase cores in the frequency division transformer 4 are slightly shifted on the magnetization characteristic curves to cause a faint imbalance between three phases, phase order can positively be determined based on the imbalance.

Abstract: PURPOSE:To control the oscillation frequency characteristic by providing two propagation paths different in propagation phase for a surface acoustic wave coupling element and controlling the gain of an amplifier, which is arranged in the input side of the surface acoustic wave coupling element. CONSTITUTION:An output electrode 11d of a surface acoustic wave coupling element 11 is connected to a power amplifier 14 through a line 13 which is a positive feedback loop of an oscillator. The power amplifier 14 divides the output of the surface acoustic wave coupling element 11 into two with the same phase and transmits divided outputs to variable gain amplifiers 15 and 16.

Title: Clock pulse generating circuit
Inventor: YOKOGAWA TAKASHI
IPC: H03K3/014
Filed: 1982-05-27
Abstract: PURPOSE:To assure the start of oscillation, by combining two monostable multivibrator elements of a CMOSIC to obtain an AND of the negative logic output of these elements and using this AND as the pull-up potential of an external resistance for decision of pulse width of one of both elements. CONSTITUTION:If the 1st and 2nd monostable multivibrators 1 and 2 are stabilized when a power supply is applied, the output Q is set at H with its AND set at L as shown in figures (a) and (b). The potential of a connection terminal 4 drops as shown in the figure (c). When the potential of the terminal 4 drops less than the threshold level, the output Q of the vibrator 1 is inverted to L. Therefore, the output of an AND gate 5 is set at H, and the potential of the terminal 4 rises up and exceeds again the threshold level. As a result, the output Q of the vibrator 2 is set at H and then inverted to L to trigger the vibrator 1. Thus a clock pulse generating circuit starts its oscillation. When the oscillation is once started, the input of the gate 5 is alternately set at L. While the output of the gate 5 is always set at H.
