Title: Cooling element for blood
Inventor: FUJII TOSHIKO
IPC: G01N33/49
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To measure, with high sensitivity, the concentration of a biochemical component in whole blood by infrared spectroscopy by a method wherein a blood-cell filtration membrane is installed on the heat dissipating face side of a thermomodule and a meshlike or porous substrate is installed on the cooling face side of the thermomodule. SOLUTION: Whole blood is dropped on a blood-cell filtration membrane 4. Blood cells in the whole blood which is dropped on the blood-cell filtration membrane 4 are left on the blood-cell filtration membrane 4, and blood plasma as a liquid is permeated through gaps 11 and a substrate 5 at a thermomodule 1 so as to reach an attenuation total-reflection prism 6. When the blood serum reaches the prism 6, a current flows from a DC power supply 3, heat on the cooling face side of the thermomodule 1 is absorbed, and the blood serum is cooled. On the other hand, the heat which is absorbed on the cooling face side is dissipated from the heat dissipating side of the thermomodule 1, the blood cells on the blood-cell filtration membrane 4 are not frozen even when the blood plasma on the cooling face side is frozen, and the concentration of a component is not changed due to hemolysis. When the whole blood is frozen and a solid component occupied in a liquid which remains due to freeze concentration amounts to about 80%, its freezing operation does not progress any more even at any low temperature.

Title: Optical reproducer
Inventor: HARIKAE SHUNJI
IPC: G11B7/135
Filed: 1980-09-17
Abstract: PURPOSE:To miniaturize an optical reproducer and to obtain a reproduced signal with high S/N, by dividing a reflected light flux into two parts by installing a wedge right after a focusing lens and obtaining a servo signal and a reproduced signal from each of the divided two light fluxes. CONSTITUTION:The reflected light flux given from a disk 6 is focused by a single lens 7 and divided into two parts by a wedge 10 to be led to photodetectors 13 and 14. The servo signals for focusing and tracking are obtained from the detectors 13 and 14, respectively. At the same time, a reproduced signal is obtained from the total sum of the outputs of detectors 13 and 14. Thus the number of optical elements can be reduced in an optical path of reflected light in comparison with the conventional optical system. As a result, not only the miniaturization but a low cost can be realized for an optical reproducer. Furthermore, the reproduced signal is obtained from the whole quantity of reflected light to increase the S/N.

IPC: H04N1/113
Filed: 1981-08-21
Abstract: PURPOSE:To perform an equispeed plane scanning with a simple constitution, by varying nonlinearly the waveform of the driving signal vibrating a light source itself applied to a scan galvanometer under the prescribed conditions and as the time elapses. CONSTITUTION:A driving current (i) is flowed to a driving coil of a scan galvanometer 6 from a driving circuit 8. Then a light source 1 itself coupled mechanically to the galvanizer 6 alternately vibrate in a + or -theta deflecting angle. The light beam of the source 1 scans horizontally the surface of the photosensitive paper 7. Here the sawtooth wave signal is added to the consine-wave signal with a certain ratio, and these added signals undergo the amplification of current to be turned into a current (i). Thus current (i) is applied to the galvanometer 6 to set the shifting speed at a certain level for the light spot on the projection face. In such way, the equispeed plane optical scanning is made possible without using an expensive polygonal mirror.

Title: Digital servo circuit with hunting-prevention circuit
Inventor: MAACHIN KEE MEESON
IPC: G05B19/23
Filed: 1979-10-11
Abstract: PURPOSE: To prevent hunting by blocking the transmission of the counting signal of an error register to a D/A converter when a marker, which indicates the increments of angles by elastic return torque, passes a reference point in the reverse direction.  
     CONSTITUTION: Instruction pulses are given to an error register 6 from signal sources 2 or 8 corresponding to the rotating direction of a motor M. The counting signal from the error register 6 is given to a motor-driving circuit 19 through a D/A converter 12. A switching control circuit 22 switches a switch Q depending on the polarity of the counting signal. A phase detector 26 gives pulses CL' or CLL' corresponding to the rotating direction of the motor M to the error register 6. When the speed signal of the motor M is zero, and the input signal to the D/A converter 12 becomes zero, the output of a NAND gate 42 becomes a "0," thereby the transmission of the bit signals b 1  and b 2  of the error registor 6 can be blocked.
