Title: Square root extracting device
Inventor: KITSUKI TOSHIAKI
IPC: G06F7/552
Filed: 1989-07-18
Abstract: PURPOSE:To obtain a high speed square root extracting device whose error is small by calculating a square root by means of the addition and subtraction of an integer and a shift operation. CONSTITUTION:At first, a squared number A is stored in a source register 1. Next, an exponent adjustment part 2 obtains A' and l which become A=A'X2<2l> and 1<=A'<4 by inputting data A. Next, X0=A':Y0=0 is set as an initial value in an X-register 4 and a Y-register 5 and the mantissa of the root is inductively obtained by a mantissa calculation part 6. Then, a mantissa adjustment part 7 sets mantissa adjustment data obtained by a prescribed processing in the mantissa part of a destination register 8 as the mantissa of A<1/2> and terminates the processing. Thus, the square root of the small error is obtained at high speed by hardware.

Title: Manufacture of rail
Inventor: KIKUCHI MASAAKI
IPC: C21D1/09
Filed: 1981-11-24
Abstract: PURPOSE:To manufacture a rail which has less thermal strain and superior strength and wear resistance by irradiating the top and side surfaces of a rail with a beam from a high energy density heat source, and thus performing a hard surfacing heat treatment. CONSTITUTION:Laser light 4a from a carbon dioxide gas laser oscillator 3 is converged through a lens 5 to obtain converged laser light 4b having enough energy density for the hard surfacing heat treatment of a rail 1. The rail 1 while moved by a moving device 6 is irradiated with said laser light 4b, thus performing the hard surfacing heat treatment continuously. To carry out said heat treatment under proper conditions, a controllr 7 controls the density and generation time of the laser light, and the moving speed of the rail 1. Consequently, the laser light is converged to about 10<4>-10<8> W/cm<2> energy density, and the irradiated area is heated speedily and also quenched, so a surface hardened layer quenched locally is obtained.

Abstract: PURPOSE:To keep a semiconductor element free of thermal stress and to facilitate the installation of a high-density outer lead to a circuit substrate by a method wherein solder is applied only after the installation on a tape carrier of a semiconductor element in a semiconductor device which includes a tape carrier, with its outer lead coated with solder, mounted with the semiconductor element. CONSTITUTION:A semiconductor element 3 is bonded to an inner lead 2 of a tape carrier 1. Next, the top surface and side walls of the semiconductor element 3 including the inner lead 2 are sealed up with a resin 4 which may be epoxy or silicone resin and the rear surface of the semiconductor element 3 is coated with a resin 5. A soldering process follows wherein an outer lead 6 of the tape carrier 1 is coated with a solder 7. This design keeps short- circuiting from taking place between fine-pitch out leads and lead strength from decreasing due to erosion by solder. With the entire process being accomplished without application of heat to the product, the result is a high-reliability semiconductor device with its semiconductor elements free of heat-caused damage.

Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To enable reduction of weight of a valve device by decreasing a load direction to a diametrally outer direction of a retainer, and preventing breakage of the retainer without requiring enlargement of the size nor highly strong material. SOLUTION: In a valve device 2, a retainer side tapered surface 18 having tapered internal side surface shape whose diameter is increased toward a top of a stem is formed on a retainer 10 which supports a valve spring 8 externally arranged on a valve stem 6 of a valve.

Title: Apparatus and method for detecting concentration of combustible material
Inventor: KITANOYA SHOJI
IPC: G01N27/416
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To enable highly accurate detection of the concentration of a combustible material by providing a concentration of oxygen measuring cell and an oxygen pumping cell on differ ent solid electrolytic layers to enhance the measuring accuracy of the concentration of oxygen. SOLUTION: Oxygen is sampled 6 monitoring the concentration of oxygen in a gap part 2 by a concentration of oxygen measuring cell 7 to be controlled to a low concentration of the oxygen to such an extent that no combustible material in the gap part 2 will be decomposed by combustion. The combustible material in the gas to be measured consumes only a slight amount of oxygen in the gap part 2 when burned on a porous electrode. The change in the oxygen is detected 7 and the oxygen is sucked 6 to be maintained at a specified concentration of the oxygen. The gas to be measured is sent to the gap part 4 via a diffusion path 3 and the oxygen is drawn outside by an oxygen pumping 8. The amount of the oxygen is measured from the value of a current flowing through the cell 8 to calculate the concentration of the combustible material.  In this process, as the cells 7 and 8 are installed on different electrolytic layers 5-3 and 5-6 , leakage current is very limited to enhance the measuring accuracy of the concentration of the oxygen. This enables accurately controlling of the concentration of the oxygen at the gap part 2 thereby detecting the concentration of the combustible material at a high accuracy.
