Title: Measuring device for thickness of pipe
Inventor: TANIFUJI SHINYA
IPC: G01B15/02
Filed: 1981-03-31
Abstract: PURPOSE:To make the sure calculation of wall thickness distributions possible in the measurement of the thickness of a pipe by determining the rate of eccentricity of an inside diameter from the transmission intensity of radiations and  the outside diameter in the transmission direction. CONSTITUTION:A radiation of intensity I0 assuming an angle theta to a Y-axis by passing through a central point O on the outside circumference of a pipe is considered, and distance OA=R1, OA'=R2 are assumed. The inside circumference of the pipe is a circle of a radius (r), and the center thereof is apart by deltar from the X-axis, and deviates by thetaA from the Y-axis. If the transmission intensity I is measured, a coefft. of transmission K is determined from the coeff. of attenuation in metal and the IO. From this and the outside diameter D in the direction  theta, K'=(D-K)<2>/4 is operated. On the other hand, as is evident from the theoretical equation K'=r<2>-deltar<2>.sin<2>(theta-thetaA), eccentricity exists if the measured value K' exhibits periodical fluctuations. The square root of the difference between the max. and min. values of the K' is the magnitude deltar of the eccentricity and the direction where it maximizes is thetaA. Thereby, the wall thickness distributions are calculated.

Title: Zoom lens with plural focusing groups
Inventor: ISHIZAKA SATORU
IPC: G02B7/105
Filed: 1990-03-01
Abstract: PURPOSE:To offer the zoom lens which has a small lens diameter and excellent performance and is capable of short-distance photography without requiring any special operation by moving >=2 lens groups or parts of them independently of each other for focusing except in an area of short-distance photography. CONSTITUTION:The lens system consists of a 1st lens group, a 2nd positive lens group, and a 3rd negative lens group in order from the object side and the intervals of the respective lens groups are shortened to vary the power from the short focus to the long focus. Thus, the lens groups are moved for focusing and the lens groups are put in partial charge of the load of focusing, so that an extreme increase in the movement quantity of one lens group can be avoided for the short-distance photography. Consequently, problems such as an increase in the diameter of a focusing lens group, deterioration in performance, and interference with an adjacent lens group at the time of an inner focus system are reduced. Further, those focusing lens groups are moved not in one body, but independently to obtain a combination of movement quantities which provides the best performance. This moving method is employed not only for the short-distance photography, but also normal photography to hold the image forming performance excellent at all times.

Title: Manufacture of semiconductor device
Inventor: YAMAUCHI SHOICHI
IPC: H01L21/76
Filed: 1995-03-07
Abstract: PURPOSE: To prevent the deterioration of device characteristics due to lattice defect by the concentration of a stress by oxidizing the sidewall near the opening of a trench when an element isolation structure is formed by a field oxide film and trench isolation. CONSTITUTION: A trench isolation structure 15 is formed on a silicon substrate 11, a pad oxide film and a polycrystalline silicon layer 17 are formed on the substrate, and then the silicon layer on the structure is selectively oxidized to form a field oxide film 19. Since the layer 17 is selectively oxidized to form the film 19, at the time of forming the field oxide film, it is prevented to form a wedgelike oxide region near the opening of the trench. As a result, no stress concentration occurs near the opening of the trench, the lattice defect of the substrate can be prevented, and the deterioration of the device characteristics near the trench can be prevented.

IPC: F16K31/06
Filed: 1980-04-11
Abstract: PURPOSE: To enable the reliable control of a gas flow within a range covering the minimum to the maximum irrespective of gas types, by a method wherein an outer diameter of a valve body in a subject solenoid-operated device for fuel gas is set based on gas having a minimum calorific value, and a solenoid start current is fixed irrespective of gas types.  
     CONSTITUTION: In case 3 types G 1 WG 3  gas are employed, the gas flow amount of G 3  is maximum and an inner diameter D of a valve seat 6 for G 3  is also maximum, presuming that the calorific value of G 3  is minimum. As a result, a buoyant force F 3  exerted upon a valve body 4 becomes maximum, and thereby a value is found from said buoyant force F 3  by following a given calculation formula so that the value is an outer diameter D' of the valve body 4, and the D' is set such that it is larger than an inner diameter D 1  of the valve seat 6 for the gas type G 1  having the maximum calorific value. Thus, a fitting load, applied to a spring 13 in order to keep a full closing condition, can be fixed, and a start current to a solenoid 9 can be fixed irrespective of the gas types. As a result, a gas current can be controlled reliably with a range covering mimimum to maximum irrespective of the gas type.

Abstract: PURPOSE:To attain the automatic circuit switching to the fault of a device set before a parity monitoring section and to improve the reliability for a circuit switching system, by adding a signal detecting/control circuit to the side of a transmission terminal station of a radio circuit. CONSTITUTION:The output of a detecting circuit 22 is set at 1 when a bipolar signal 100 is normal and then fixed at a level 1 or 0 in case a converting circuit 21 has a fault. Then the output of a signal cut-off detecting circuit 35 is set at 1, and a frame synchronizing signal is cut off. Thus the frame synchronous multiplication is not satisfied, and an output signal 107 contains no frame synchronizing signal bit. Then no frame synchronism is obtained at a reception code processor 6a at the reception side. Thus a fault detecting circuit is actuated to switch the circuit.

Filed: 1984-03-13
Abstract: PURPOSE:To ensure the satisfactory sliding performance of a magnetic head without deteriorating the magnetic recording characteristics, by forming a lubricant layer of molybdenum disulfide on the surface of a slider part of a floating type magnetic head. CONSTITUTION:This magnetic head consists of a head part 1 forming a magnetic circuit which performs the record/reproduction and a slider part 2 which maintains the stable floating with a recording medium such as a magnetic disk, etc. Both parts 1 and 2 are joined together via a section A-A. The head part 1 contains a coil 11 which performs the electromagnetic conversion, a magnetic pole 12 and a gap part 13. A ceramic binder containing molybdenum disulfide is baked on the side of the slider part 2 opposite to the surface of the recording medium and then polished or ground into a prescribed form. The part 2 is bonded to the part 1 like a conventional magnetic head after a slider is completed. Furthermore no loss is produced since no molybdenum disulfide is attached to the areas near the pole 13 and the part 13 which affect greatly the characteristics of a magnetic head. This causes no deterioration of the magnetic recording characteristics.
