Title: Oscillation circuit
Inventor: MURAKI YOICHI
IPC: H03B19/00
Filed: 1991-07-30
Abstract: PURPOSE:To realize a frequency divider circuit in which the duty ratio of a clock pulse frequency-divided by an optional frequency division ratio is nearly 50% by ANDing a frequency division output resulting from odd number frequency division to a reference clock pulse and a frequency division output resulting from odd number frequency division to an inverse of reference clock pulse and outputting the AND output. CONSTITUTION:The circuit consists of a reference clock pulse generator 1, 1st and 2nd 1/N frequency divider counters 2, 3, AND gates 4-6 and an inverter 7. Then a 1st frequency division output obtained by applying 1/(2n+1) frequency division to a reference clock in which an interval between H and L states differs in one period and a 2nd frequency division output obtained by applying 1/(2n+1) frequency division to an inverted clock pulse being inverse of a reference clock in which an interval between H and L states differs in one period are ANDed in an AND gate. Thus, the interval of the H and L states in one period is made equal to each other. Thus, the circuit is realized, in which the frequency of the reference clock pulse is subject to 1/(2n+1) frequency division and its output duty ratio is nearly 50%.

Abstract: PURPOSE:To prevent uncontinuous change in a steering angle at junction of change positions, by enlarging a steering ratio in dependent upon increase in an engine speed. CONSTITUTION:A steering direction of front wheels 1 is inputted as an output 4a from a front wheel steering angle sensor 4 to a controller 10, and whether a phase of rear wheels 2 is to be the same phase or reverse phase relative to the front wheels 1 is determined by the controller 10 in dependent upon a change position detected by a change position sensor 12a and in accordance with a predetermined pattern. A steering ratio is sequentially increased in response to sequential shift-up operation from a second speed position, and it is increased in response to an engine speed at each engine position.

Abstract: PROBLEM TO BE SOLVED: To make it possible to dry grains to a desired water content value by keeping the whole grains filled up in a storage section in an even state when filling up and drying the grains so that grain layers having different water content values may be accumulated in the storage section inside a grain dryer. SOLUTION: This dryer forms a storage section W on the upper half area in an equipment body 1 and arranged a drop passage of grains, a hot air conduction passage and an exhaust air passage on both sides on the lower half side and multi-series of drying sections (Y) furnished with a rotary shutter 3 on the lower end of the drop passage area provided on both sides in a row in structure. In this case, the grains are arranged to flow past the drop passage of the drying sections Y which stand in a row from the storage section W and to be returned to the storage section W, thereby circulating the grains. In the means time, the grains are bathed with hot air and dried up.  In this drying method, the operation of the rotary shutters 3 of the parallel drying sections Y is controlled so that the total output of the grains may be diversified in their relative relation, thereby forming diversification in the circulation speed at a different site in the longitudinal direction and drying up the grains in the storage section W while they are being agitated and mixed vertically.

Abstract: PROBLEM TO BE SOLVED: To make it possible to perform direct detection by forming the hybrid of the sample, wherein the first nucleic acid and protein are fixed, and the sample, wherein the second nucleic acid and protein are fixed, and detecting whether the samples have formed the hybrid or not. SOLUTION: The first nucleic acid and protein are fixed to the waterproof coating of a supporter (crystal oscillator) 12 and inputted into buffer solution 13. The temperature of the buffer solution 13 is increased with a temperature control part 11 to the temperature, at which the first nucleic acid and protein to become a mold and the second nucleic acid and protein to become a specimen do not form hybrid. After the specimen is added into the buffer solution 13, the temperature is slowly lowered.

The formation of the hybrid is performed on the supporter 12, and the mechanical load state is changed. The detection can be performed as the change in oscillating frequency.  As the supporter 12, the device having the less temperature dependency in the vicinity of the forming temperature of the hybrid is used. When this is not ignored, the temperature is corrected.
