Abstract: PURPOSE:To make high sensitivity measurement by previously sticking a material forming a network structure to the surface of a piezoelectric vibrator. CONSTITUTION:Fibrinogen, etc., are stuck to the surface of the piezoelectric vibrator (crystal vibrator) 8 in the following manner: The prescribed soln. of the fibrinogen, etc., is first put into a measuring cell 7 set with the vibrator 8 and is rested for a prescribed period of time at room temp. The soln. is thereafter removed and washed. The material for forming the network structure is, therefore, previously stuck to the surface of the vibrator 8 in such a manner. The network structure glows with the material stuck to the vibrator as the end part of the network structure and increases the mass over the entire part of the photosensitive 8 when the gelatinization reaction progresses at the time of measurement. The oscillation frequency is changed by a change in the mass and this change in the oscillation frequency is measured. The material forming the network structure on the vibrator surface is previously stuck to the vibrator in such a manner and such vibrator is used as the measuring element, by which the high-sensitivity measurement of the gelatinization reaction arising from blood clotting is executed.

Title: Brightness control circuit
Inventor: SOGO SHINSUKE
IPC: G09G5/02
Filed: 1990-05-29
Abstract: PURPOSE:To obtain a changeover switch close to a linear characteristic by connecting a series circuit comprising a diode and a resistor in parallel with a resistor connecting in series with an output terminal of a brightness control signal so as to increase a lower change quantity of a variable control range. CONSTITUTION:A series circuit comprising a diode 8 and a resistor 9 is connected in parallel with a resistor 2. When a lower control range in the variable control range is selected, a current flowing to a FET 7 passes through a pull-up resistor 4 and flows to the resistor 2 or becomes a forward current of the diode 8, resulting in flowing to the resistor 9. That is, since the entire variable control range depends on the series circuit comprising the resistor 2, the diode 8 and the resistor 9, the current flowing in the lower range of the variable control range is increased and a change in a control voltage 6 is increased. Thus, a changing characteristic close to a linear characteristic is obtained over the entire variable control range.
