Title: Method for testing main storage device
Inventor: TORITANI SHOZO
IPC: G06F12/16
Filed: 1987-04-01
Abstract: PURPOSE:To quickly detect an important fault such as a common part device fault by checking the generation of a fault on an optional address in a test of a main storage device. CONSTITUTION:The main storage device is tested by initializing (S1) a device number and then the test of the initial address is executed (S2). When the test result is YES (S3), the tests of all main storage devices are not ended (S4) is confirmed, the device number is updated (S5) and the operation is returned to procedure 2 for testing the initial address of the succeeding device. If the test result is NO in the procedure 3, abnormality is detected (S6) and these procedures are ended. When the tests of the 1st addresses of all the main storage devices are ended, the operation is jumped to procedure S11. Thus, an important fault such as the fault of a common part device can be quickly detected by checking the generation of a fault in an optional 1st address.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a source offset by forming a trench gate conductor layer and a gate insulating film in a trench and on the main surface of the periphery of the trench in a semiconductor device having a FET of a trench gate structure, in which a conductor to be a gate is provided in a trench extending on the main surface of a semiconductor substrate. SOLUTION: A trench gate 4 of a MISFET of this type is formed in a trench extending to an n-type second semiconductor layer 2a to be a drain region from the main surface of a semiconductor substrate via a multi-layer gate insulating film 5 formed of a thermal oxide film and a deposition film, and is formed of polycrystalline silicon doped with impurities, for example. The top surface of the trench gate 4 is higher than the surface of a third semiconductor layer 2c to be a source region, that is, the main surface of the semiconductor substrate. Therefore, this can prevent the trench gate 4 from being off the source region, that is, a source offset, even if the source region is made shallow. It is desirable that the top surface of the trench gate 4 is formed almost flat or convexly.

Abstract: PURPOSE:To enable the measurement of an optical fiber in comparison with the distribution  parameter of refractive index at a certain wavelength by utilizing a difference in the velocity of  light propagation near the optical axis from that propagating in the perimeter near the boundary  between the core and the clad thereof. CONSTITUTION:A laser beam modulated by a sine waveform or the like propagates near the  optical axis through a pin hole or the like while propagating in the perimeter near the boundary  between the core and the clad through a ring-shaped space filter or the like passing through a  fiber 3 to be measured and beam split 5 and then, is separately received and detected with detectors 91 and 92. A phase difference theta of both detction outputs is measured with a phase difference  measuring device 10 based on the equation I on the outputs. The phase difference turns positive  or negative depending on whether the propagation speed at different parts of an optical fiber is  larger or smaller than the distribution parameter of refractive index at a certain wavelength,  which permits the measurement of the fiber on the variation with respect to the distribution  parmeter of the refractive index as well as the wavelength involved. In the equation, f represents  the frequency of a modulated signal, L the length of an optical fiber, lambdai and lambdao optical axes and  taui and tauo delayed propagation times in thellight wavelength in the perimeter.

Abstract: PROBLEM TO BE SOLVED: To decrease a resistance value per one tab when it comes closer to the core of an element and thereby reduce generation of heat near the center of the element, by making the intervals between electrode extraction lead tabs smaller as it comes closer to the core, in an electrolytic capacitor. SOLUTION: A capacitor element is made by fastening electrode extraction lead tabs 23 to an anode foil 21 and a cathode foil 22, then winding the anode and the cathode foil 21, 22 around an aluminum pipe as a core through a separator, and then fixing the wound body with a tape and then impregnating it with an electrolyte. At that time, the closer to the center of the anode and the cathode foil-wound body, the narrower the width of divided sections for the electrode extraction lead tabs becomes. The electrode extraction lead tab 23 is fastened to the center of each of the divided sections. The more electrode extraction lead tabs are used in the capacitor element, the more effect is brought about.  In this electrolytic capacitor, the rate of temperature of the outside part of the wound body to the center is about 0.95-0.96, thereby unifying generation of heat in the wound body due to ripple current and reducing the increase in temperature in the entire wound body.
