Title: Fatigue precracking former for fracture toughness test piece
Inventor: NARIMOTO ASAO
IPC: G01N3/32
Filed: 1986-06-30
Abstract: PURPOSE:To obtain an even test piece, by measuring the length of a precracking by a bending displacement of a fracture toughness test piece to apply a specified repeated load until the length reaches a specified value. CONSTITUTION:A fatigue tester 11 is driven to form a fatigue precracking at a chip 9a of a fracture toughness test piece 9. In other words, a vibration exciter 13 is vibrated to provide a repeated load on the top of the test piece 9 with a working element 13a. A deflection detector 14 measures a displacement of the working element 13a at the vibration exciter 13. A control circuit detects the length of a cracking generated in the test piece 9 based on the deflection amplitude of the test piece 9 determined from the results of detection from the detector 14. In this manner, a specified precracking is formed in the test piece 9 and an output is sent out from the control circuit. Then, the subsequent fracture toughness test piece 9 is placed on a support base 10 to form a precracking again.

IPC: D03D51/28
Filed: 1992-05-18
Abstract: PURPOSE:To enable the sensing of warp yarn breakage simply by wrapping the weft yarn around a winding drum in a slight number of turns even when any of many warp yarns in a loom are broken. CONSTITUTION:A sensing wire 21 is stretched relatively to a winding drum 10 arranged in its condition to cross many warp yarns in a nearly parallel state with an interval from the winding drum 10. Even when any of the many warp yarns are broken, the warp yarns are wrapped around the winding drum and the sensing wire, which is drawn near toward the winding drum. Thereby, the sensing wire is brought into contact with the nearest electrode for contact in plural electrodes 30 for the contact scatteringly installed in the longitudinal direction of the sensing wire to provide an electrical signal.

Title: Divided driving control type internal combustion engine
Inventor: ISHIDA YASUHIKO
IPC: F02M13/02
Filed: 1977-12-19
Abstract: PURPOSE: To reduce the rate of fuel consumption by providing separate control mechanisms for fuel supply and suction air amount to each cylinder group to increase the suction air amount to cylinder groups to be off.  
     CONSTITUTION: In this construction, throttle valves 5a and 5b are interlocked to be different in their operating speeds. The throttle valve 5a is perfectly closed in an idling position when the step-in amount of an accelerator pedal is zero. At this stage, the first cylinder group is supplied with fuel according to the signal from an air-flow meter 7a, while the second cylinder group is not supplied with fuel by the interception of a switch 30. In this state, the throttle is fully opened, but the fuel is not supplied. As the accelerator pedal is stepped in, the throttle valve 5b is also opened, and fuel is supplied by signals from respective air-flow meters 7a and 7b. Since the amount of suction air is increased for cylinders out of operation, the rate of fuel consumption is greatly reduced.

IPC: G01C19/72
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To control nonreciprocity (Shupe effect) due to vibration and heat to a minimum, and make it adjustable by controlling and adjusting geometrical factors of a coil subjected to potting treatment. SOLUTION: Geometrical factors of an optical fiber coil subjected to potting treatment (potting treatment length, number of turns per layer, number of layers and thickness of an adhesion layer) are set so as to fit to the restriction of a system/gyroscope such as the maximum allowable volume and the desired Sagnac magnification. As a variable from geometrical factors, parameter, e.g. the thickness of an adhesion layer is selected, a plurality of coils are wound, and the selected geometrical factors are changed. Each Shupe bias (vibration response or thermal gradient response) is measured. The optimum value and the allowable degree (tolerance) of the geometrical factor are selected. In the course of coil manufacturing, the geometrical factors are controlled to be in a specified tolerance.

Abstract: PROBLEM TO BE SOLVED: To provide a navigator capable of easily making plural expanded guide maps in different points by storing a basic map as an original for making a landscape map at a guide point, cutting out an arbitrary range of the stored basic map, and displaying the cut-out graphic by expanding/contracting it to a prescribed display area.

Namely, when the reference image data is created based on the data at a distance 300 m before the cross-point and a present position is 200 m before the cross-point, the cut-out size is proportional to the distance and is 200/300 of the reference image data. Thus, the image data for plotting lots of expanded guide maps from less reference image data are created.
