Title: Oscillator biosensor system
Inventor: KARUBE MASAO
IPC: G01N33/543
Filed: 1986-03-10
Abstract: PURPOSE:To improve the accuracy of a measurement, and to execute a repeated use by integrating an oscillator biosensor into a liquid passing type device. CONSTITUTION:First of all, an adsorption matter is eliminated by making a glycine hydrochloric acid solution 14 of about pH2.8 flow into a cell 4. Subsequently, the inside of the cell 4 is replaced with distilled water 12, and by making the distilled water 12 flow at a prescribe speed, a measurement of an oscillation frequency of a crystal resonator biosensor 1 is executed. Next, a human IgG solution is made to flow into the cell 4, and made to react to protein A or an antihuman IgG antibody which is stabilized to the sensor 1 for 30min or so. Thereafter a nonsingular adsorption matter is eliminated by making for instance a 0.5N salt solution 13 pass through. Also, the inside of the cell 4 is replaced with the distilled water 12, and by making the distilled water 12 flow through, a measurement of an oscillation frequency is executed. By a variation of this oscillation frequency, the human IgG solution density is measured. Thereafter, by making the glycine hydrochloric acid solution 14 flow, and eliminating a singular adsorption matter, the device is used again.

Title: Coder
Inventor: YANO KAORU
IPC: H03M1/06
Filed: 1981-04-10
Abstract: PURPOSE:To obtain the stable characteristics in both the voiceless and voiced modes of an input analog signal, by adding a drift compensating circuit of a simple constitution to a feedback type coder to form a midtread type coder. CONSTITUTION:The input analog signal supplied to an input terminal 14 is sampled and held a sampling and holding circuit 1. This held voltage is supplied to an addition amplifier 2 and then led out through an output terminal 15 in the form of a PCM output. In case when a sequential feedback type coding circuit is turned into a bipolar coder of 4-bits, a positive side switch 12 is driven by a positive side detector 8 when the quantizing level of the PCM output emerging at the output of an FF6 is positioned at +2-+8. Thus the voltage held at an integrator 7 is discharged. When the quantizing level is set at -1--8, a negative side switch 13 is driven by a negative side detector 9 to charge the voltage held at the integrator 7. The output of the integrator 7 is applied to the input of the amplifier 2 to give a compensating control to the amplifier 2. As a result, the noise characteristics are obtained in good condition for the reproduced signal in the voiceless input mode.
