Abstract: PURPOSE: To improve measurement accuracy without requiring the accuracy of circuit parts by connecting a reference resistance to an oscillator, performing counting with a counter, then connecting a temperature measuring resistor, performing counting and performing specified operations.  
     CONSTITUTION: An astable multi 11 is formed by operational amplifiers I 1 , I 2 , a capacitor C, a reference resistance R 1  and a temperature measuring resistor R 2 . Different oscillation frequencies f 1 , f 2  are generated through selection of R 1  and R 2 . On the other hand, the output f 0  of a reference oscillator 12 is counted for a fixed number in a control circuit 13, by which the square wave of a fixed time width is created. Then, the output of the control circuit 13 as a control input and the output of the astable multi 11 as a signal input are passed through an AND gate 14 and are displayed in a display circuit 17 through a counter 15 and arithmetic circuit 16. This enables the apparatus to be formed without requiring the accuracy of circuit parts, and since R 2  is connected after connection of R 1 , the information for the new detecting temperature may be obtained and accuracy improved.

Abstract: PURPOSE:To magnify and reduce a picture data at an optional magnification by inputting a value N to an circuit as a 1st value when the adder circuit outputs no carry signal and inputting a value 2P-M+N to the adder circuit when the circuit outputs the signal. CONSTITUTION:When a carry signal CY is not outputted from a P-bit adder 5, a multiplexer 10 selects a data of a register 8 and when the carry signal CY is outputted, the multiplexer 10 selects a data of a register 9 respectively and the data is latched in a latch 6. For example, when a picture data is magnified or reduced to a multiple of N/M, a numeral N is set the register 8 and a numeral (X+N) (=2P-M+N) is set to the register 9 respectively. In the case of reducing the picture data, a reference clock CLKB is outputted to a terminal S and given to a P/S circuit 1, and a clock CLKC is outputted to a terminal D and given to an S/P circuit 3. In the case of magnifying the picture data, the reference clock CLKB is outputted to the terminal D and given to the S/P circuit 3, and the clock CLKC outputted to a terminal S and given to the circuit 1.

Title: Radioactive microsphere that is excellent in chemical durability and method for manufacturing it
Inventor: KOKUBO TADASHI
IPC: A61K51/12
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To obtain radioactive microspheres that are excellent in chemical durability and can directly emit radiation for a long term through the implantation of them near a tumor in a patent's body by composing them of crystals of an oxide containing radioactive yttrium of a specific wt.%. SOLUTION: As to the composition of radioactive microspheres, crystals of an oxide containing radioactive yttrium of 47 wt.% or more account for 99% or more of them and unavoidable compounds make up the rest. The content of yttrium in yttria is 78 wt.% or more when crystals of an oxide are Y2O3, whereby an affected part can be irradiated with 2.47 times as much radiation dose as that in the use of glass. YPO4 and a mixture of Y2O3 and YPO4 are also acceptable as crystals of an oxide. When they are YPO4, the lower limit of the content of yttrium in the microspheres as a whole drops to 48 wt.% but the effect of increasing radioactivity by phosphorus with a long half-life period is made.  In addition, it is acceptable that the microspheres are covered with a coating of silica, titania, alumina and the like, which enhances the resistance to acids and enables the long-term irradiation with radiation.

Title: Color video signal recorder/reproducer
Inventor: MIZUTANI KEIICHI
IPC: H04N9/80
Filed: 1979-05-28
Abstract: PURPOSE:To ensure the assured decision in both the SECAM and PAL systems with no malfunction, by setting the killer threshold level of the SECAM color killer detection circuit of the reproducing time than that of the recording time. CONSTITUTION:Diode D2, resistance R2 and capacitor C3 each are provided to the SECAM color killer detection circuit. As a result, the DC voltage is applied to terminal 4 only at the reproducing time. Accordingly, diode D2 conducts at the reproducing time, and capacitor C3 is connected to the collector of transistor Q2 constituting the tuning-type amplifier. In this connection, the tuning frequency is shifted, and the collector output level of Q2 lowers down at the reproducing time. Thus the color killer threshold level of the reproducing time becomes higher than that of the recording time. As a result, the malfunction caused by reproduction of the PAL color signal can be eliminated without impairing the detecting capacity of the SECAM color signal.
