Title: Floating point arithmetic unit
Inventor: TAKAKUWA MASAYUKI
IPC: G06F7/00
Filed: 1990-11-05
Abstract: PURPOSE:To fix a single rounding position for omission of a complicated rounding position detector circuit and to perform a floating point arithmetic operation at a high speed by applying the normalization processing and then the rounding processing to the arithmetic result of the mantissa of two floating point numbers whose digits are matched with each other. CONSTITUTION:The number of leading zero bits of the mantissa arithmetic result are counted by a leading zero detector means 11, and the mantissa arithmetic result is shifted to the left by a left shifter 12 by an extent equal to the count value of the leading zero bits. The output of the shifter 13 is inputted to a rounding adder 13. The rounding positions are fixed to the single one owing to a fact that the output of the shifter 12 is normalized. As a result, a rounding position deciding circuit can be omitted and the hardware quantity of the adder 13 itself can be reduced. Thus the rounding processing is carried out at a high speed.

Abstract: PURPOSE: To adjust the focus of a camcorder at a high speed correspondingly to the inclination of video detecting data, without providing special microprocessors for driving a lens by controlling the moving speed of the lens according to the inclination of the data. CONSTITUTION: In the camcorder being a VTR provided with camera, the detected data corresponding to the video data of the present frame and the last frame are latched to the latch circuits 203 and 202 of an object movement diagnosis section 200. The inclination of the video detection data are found by processing the latched contents by means of a subtractor 205 and an absolute value generator 206 and dividing the difference between the latched contents by the moving speed of a lens 100. A comparator 207 discriminates whether or not the lens 100 has reached the vortex by comparing the inclination with a reference value, and a microprocessor 210 changes the moving speed of the lens 100 to a low speed from a high speed, as the inclination becomes closer to the reference value.  Therefore, the focusing adjustment of the lens 100 corresponding to the inclination of the video detected data can be performed quickly, without providing special microprocessors for driving the lens 100.

Title: Non-fluid liquefied gas and method of adsorbing liquefied gas
Inventor: MIZOHATA HIROMICHI
IPC: F17C11/00
Filed: 1986-12-15
Abstract: PURPOSE:To prepare a safe gaseous liquefied gas, by adsorbing a liquefied gas on powdery fine particles packed in a vessel. CONSTITUTION:A vessel 1 is previously packed with powdery particles 6, e.g., SiO2.nH2O (n 0.1) having a particle diameter of about 0.007mu. An upper lid 1a is put on the vessel, and the vessel is filled with, e.g., an LP gas, through a valve 3, so that the LP gas is adsorbed on the fine particles and frozen like a shaved ice. Therefore, no liquid exists within the vessel. When the LP gas is to be used, the valve 3 is opened, which causes the LP gas to be vaporized and ejected. The size of the fine particles is preferably 0.007-10mu. The larger the particle size, the lower the adsorption of the liquefied gas. Examples of the liquefied gas include flon 11, dimethyl ether, and a mixture composed mainly of them besides the LP gas. Examples of the fine particle include TiO2, Al2O3, Fe2O3, and other organic and inorganic powders besides SiO2. The use of the vessel in a horizontal state or an inverted state brings about no ejection of the liquid.
