Title: Sampling device of plasma
Inventor: NAITOU TAMEO
IPC: G01N33/48
Filed: 1984-03-26
Abstract: PURPOSE:To separate effectively the plasma and red cells, etc. in blood by making use of the separating effect occuring in the difference in the flow rate of the fluid flowing in capillaries. CONSTITUTION:When a piston on a synringe 5 side is depressed and actuated, the blood drawn in the syrine 5 flows at a specified flow rate in the small-diameter tubes 12 in a pipe 1 and moves to the inside of a syringe 6. By and large, the liquid flowing in a fine tube 12 is lower in the flow rate in the part nearer the wall of the tube 12 as shown by a flow rate distribution curve V and if a component having large specific gravity is contained in the liquid, the phenomenon that the component having the large specific gravity gathers to the center of the tube arises. The larger blood cells among the blood cells gather consequently and more increasingly to the center of the tube and part further from the tube wall and therefore the rate that the blood cells close the hole punched to the tube wall can be considerably decreased by maintaining the adequate flow rate. The plasma passes through the many holes punched to the walls of the tube 12 and is gathered into the space between the tubes 12 and the pipe 1. The gathered plasma is drawn through a pipe 1a for taking out.

Title: Color television camera
Inventor: IIDA TATSUHIKO
IPC: H04N9/07
Filed: 1979-05-14
Abstract: PURPOSE:To make it possible to obtain a stable color signal even if the form of an electron beam is changed, by scanning the electron beam of a single tube-type color image pickup tube in the extension direction of respective filters which are arranged in parallel. CONSTITUTION:Since the electron beam of image pickup tube 14 is scanned horizontally along the extension direction of respective filters 15a-15c, different color signals are output successively from image pickup tube 14 at every one horizontal period. Signals output from image pickup tube 14 in this manner pass through preamplifier 16 and are added to signals delayed by the 1H period and the 2H period by 19 to become a luminance signal. Meanwhile, the output of amplifier 16 is supplied to modulator 22 through variable gain amplifier 21 to generate the modulation  wave of each color signal. These luminance signal and color modulation wave are  added in 25 to become a picture signal. Thus, since the color signal is changed at every 1H, the form of the electron beam is independent of the color signal, and a  stable color signal can be obtained.

Title: Electronic musical instrument
Inventor: WACHI MASATADA
IPC: G10H1/053
Filed: 1990-03-09
Abstract: PURPOSE:To control touch response properly by providing a transition signal generating means which outputs a transition signal and approximating the transition signal to an after-touch signal speedily. CONSTITUTION:The transition signal generating means 92 outputs the transition signal which has a value corresponding to an initial touch signal at 1st specific time and varies gradually toward the after-touch signal after the 1st time. A selecting means 93 selects the after-touch signal in the beginning of sound generation, the transition signal after the 1st time, and then the after-touch signal again when the deviation between the level of the transition signal and the level of the after-touch signal becomes less than a specific value, thereby outputting the selected signal. Then a musical sound signal is controlled according to the output signal of the selecting means 93. The output signal of the selecting means 93, therefore, varies smoothly from the initial-touch signal to the after-touch signal. Consequently, the control is changed smoothly to generate an extremely natural musical sound.

Abstract: PROBLEM TO BE SOLVED: To obtain a solar power generation system in which the mounting method of a plurality of auxiliary solar cells is optimized and in which the influence of the shadow of the sun due to a partial cloud, the shade of a of a tree or the like is reduced as far as possible, by a method wherein the plurality of auxiliary solar cells are installed additionally and the in solution condition of a main solar cell is grasped precisely. SOLUTION: A solar cell array 1 is composed of a main solar cell 11 in which modules are arranged and of a first auxiliary solar cell 12 and a second auxiliary solar cell 13 which are installed for control use. Since the first auxiliary solar cell 12 and the second auxiliary solar cell 13 are arranged symmetrically with respect to the central axis of the solar cell array 1, the output voltage of the first auxiliary solar cell 12 and that of the second auxiliary solar cell 13 generate a large difference according to intensity of insolution. The output values are inputted to a voltage instruction device 2, and the two values are compared by the voltage instruction device 2 so as to read an absolute value. In the case of this condition, the output voltage may be judged according to a larger output voltage.  When a solar power generation system is controlled by using the mean value of the two output values, its accuracy becomes better than in the case in which one out of the two output values is used.
