Title: Time division radio communication system
Inventor: HIYAMA TAKASHI
IPC: H04J3/00
Filed: 1987-03-02
Abstract: PURPOSE:To obtain the diversity effect with simple system constitution by varying sequentially a transmission/reception station local oscillation frequency supplied to a transmitter-receiver based on frame structure so as to obtain plural carriers. CONSTITUTION:A local oscillation signal of transmission/reception local oscillators 10-1-10-n is sent to a transmission section 3 and a reception section 4 at a predetermined period sequentially via switch sections 8, 9 by a control signal from a control section 7. On the other hand, a signal from an input terminal 11 is stored in a transmission logic circuit 5, sent to the transmission section 3 by a frame structure shown in figure to modulate a carrier. Thus, the signal Si is sent in a carrier fi. Moreover, the carrier from an opposite station is mixed with the local oscillation signal of the oscillators 10-1-10-n and demodulated. Thus, when signals S1-Sn in the frame are made identical, the frequency diversity effect changing the carrier frequency by time is expected.

Title: Testing method of hepatic function
Inventor: YOSHIBA MAKOTO
IPC: A61B10/00
Filed: 1981-03-30
Abstract: PURPOSE: To discover the hepatic disorder due to drugs, e.g. alcohol, and test the hepatic function, by measuring the trehalase activity in blood, blood plasma or blood serum.  
     CONSTITUTION: Trehalase is trehalose hydrolase which is a kind of disaccharide. The measurement of the enzymic activity is carried out by determining the amount of glucose formed by the hydrolysis of the trehalose. For example, a solution of the trehalose as a substrate is reacted with a blood serum of a speciment, and the reaction is stopped by heating. The glocuse concentration is measured by the enzymic method. A buffer solution containing no substrate as a control is added to the blood serum, and the same treatment is carried out to determine the glucose concentration. The trehalse activity is obtained by the difference in the glucose concentration. The trehalase is present in the hepatic cellular membrane, etc. and appears in blood in hepatic diseases.

Abstract: PURPOSE: To prevent the generation of data omission and incorrect data by judging the validity of decoded data and executing time diversity operation. CONSTITUTION: A transmitting side encodes an interlaced signal obtained by interlacing an n-bit delay signal string in a signal string with an input digital signal string and transmits the interlaced signal to a transmission line. A receiving side separates a delay signal and a no-delay signal from decoded data decoded by a transmission line decoder through a shift register 20 and phase convertes 24, 25 and selects and outputs a valid signal by a selector 33. A combination judging circuit 28 judges the degree of coincidence between a valid gate signal expressing the validity/invalidity of the decoded data and the separated signal and controls the switching of the selector 3 and the synchronism of the separated signals.

Abstract: PURPOSE:To enhance Mn removing effect by a method wherein the water to be treated in an ozone contact tower is sampled to measure the optical characteristics of the sampled water to determine the injection amount of ozone and the concn. of Mn(V11) is preset to optically detect the reddish pink color of Mn(V11) and the detected value is compared with a set value to control the injection amount of ozone. CONSTITUTION:The sampled water 6 from the water to be treated in an ozone contact tower 2 is taken out to be sent to an optical device having a flow cell and the absorbancy or transmissivity of the water 6 is measured at a wavelength of 540nm. This measured result is inputted to a personal computer 9 and a predetermined calibration curve is used to determine the concn. of ozone. This concn. is compared with preset initial concn. and, in a case higher than the measured value, the personal computer 9 operates an inverter 10 to lower the supply amount of ozone. When ozone is insufficient in the opposite case, the supply amount of ozone is increased. When the concn. of Mn(II) is low, reduction and filtering are performed in an activated carbon adsorbing tower 4.
