Title: Pulse width modulating circuit
Inventor: UNOSAWA NOBORU
IPC: H03K7/08
Filed: 1981-09-28
Abstract: PURPOSE:To simplify the circuit and to improve the performance, by using one switching element, and flowing a current from a reference voltage circuit steadily to an amplifier. CONSTITUTION:A DC signal E1 to be measured is applied to an input terminal 1. An integrator consisting of a capacitor C and an amplifier U1 sums and integrates a current ip from a reference voltage Ep, a current E1/R1 from the DC signal E1, and a current iN from a reference voltage EN. Further, a switching element S1 is controlled so that the algebraic sum of three currents flowing to the integrator is zero at one period of integration. Formula as shown is obtained, where T is the time of one period of integration, T1 is a time when the S1 is turned on at the T, and T2 is the residual time. Thus, the DC signal E1 to be measured can be obtained by counting the T1 and T. By adopting the automatic zero system, the remaining zero can automatically be corrected, giving no effect on the measuring accuracy.

Title: Air dynamic pressure bearing device
Inventor: TSUNO RYUKICHI
IPC: F16C33/24
Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To enable suppression of generation of abraded powder from a dynamic pressure bearing part of an air dynamic pressure bearing device with a simple structure. SOLUTION: At least one of a shaft member 11 and a bearing member 21 is made of magnetic material attracting abraded powder generated from a dynamic pressure bearing surface. The abraded powder from the dynamic pressure bearing surface is largely held by the magnetic material due to its magnetic force without floating from the sliding surface.

IPC: C08J5/18
Filed: 1984-07-24
Abstract: PURPOSE:To obtain the polyolefin family sheet excellent in impact resistance by rolling crystalline polyolefin family resin in biaxial direction under the temperature condition satisfying the formula, keeping the time equal to 30min or more. CONSTITUTION:It is necessary that rolling temperature T is in the range of Tms-5 deg.K<=T<=Tms+5 deg.K, and preferably in the range of Tms-3 deg.K<=T<=Tms+ 3 deg.K. here, T; rolling temperature, Tms: the melting point of sheet or block like material before rolling. In said temperature range, material must be rolled, while keeping the time equal to 30min or more, and its rolling must be carried out in biaxial direction. This sheet has not the defect of imferior adapting to a mold, and also there is not the sag impeding the process, when a large molded product is produced by vacuum molding or pressure molding. Consequently, the impact resistance of the sheet is heightened, and also its strength and Young's modulus are improved. As the molecular structure of polyolefin has no necessity of denaturation, its original characteristics such as mechanical strength, electrical property, water resistance and chemicals resistance are kept as they are.
