Patent JP-H05338885-A (JP)
Title: Fabric conveyor
Inventor: YOSHIMURA HIDEO
IPC: D04B35/10
Filed: 1992-06-05
Abstract: PURPOSE:To permit a knit fabric conveyor to stably carry out a conveying operation on the basis of natural length by providing drive motors for rotation to rollers for conveying predetermined knit fabric and for controlling the rise of the knit fabric, and disposing the rollers in parallel to each other, and disposing between the rollers a sensor for detecting the rise of the knit fabric. CONSTITUTION:A plurality of rollers 1, 2 each provided with a drive motor for rotating it are disposed in parallel and a sensor 3 for detecting the rise of knit fabric 4 is disposed therebetween. In this case, when a signal output from the sensor 3 indicates no rise of the knit fabric 4, one of the rollers (2) is rotated so that the knit fabric 4 rises between the rollers 1, 2. The other roller 1 conveys the knit fabric 4 proportionately to its number of rotation. As a result, the knit fabric 4 rises between the rollers 1, 2 and is therefore held in a natural condition. Thereby the influence of loads produced by the weight of the expansible knit fabric 4 is eliminated and the fabric conveyor is permitted to stably carry out a conveying operation on the basis of natural length.

Title: Constitution of noncontact type optical distance detection probe
Inventor: IDESAWA MASANORI
IPC: G01C3/06
Filed: 1987-06-11
Abstract: PURPOSE:To reduce the size of the whole device and its weight by arranging a mirror between an object and a linear gauge mark director, and deflecting and scanning a light beam. CONSTITUTION:The light beams B of a light beam deflecting and projecting means BS is deflected and scanned on the surface of the object to form bright points T and T', light beams from which are reflected by mirrors M1 and M2, and M3 and M4 arranged at the periphery of a device shaft and incident on linear gauge mark direction detectors DS1 and DS2, and DS3 and DS4. Then the detector DS1 detects the positions of images I and I' of the bright points by a linear image position detecting element S and its operation is the same with an observation of bright points IV and IV' by a virtual detector DS1V at a mirror image position. This device, therefore, detects the image position with long base line length equivalent to trigonometry by the virtual detector DS1V, and consequently the width of the device is narrowed down to reduce the size and weight of the whole device.

Abstract: PROBLEM TO BE SOLVED: To avoid generation of revolving stall in a small flow territory by radially forming a plurality of grooves on at least one side wall of opposed walls through the flow passage of a diffuser with no vane in which the discharge flow from an impeller flows. SOLUTION: A diffuser with no vane 1 is constituted of walls 1a, 1b opposite to each other through a flow passage 3 opening a discharge port 3a on the outer circumference, and a plurality of grooves 2a, 2b are radially formed on the inner faces of the respective walls 1a, 1b. At operation, an impeller 5 is rotated in the arrow mark direction, liquid flowing in a suction port 4 is discharged from the discharge port 3a through the flow passage 3 by the impeller 5 as shown in the arrow mark.  At this time, inward flow is caused by pressure gradient in the radial direction within the grooves 2a, 2b so as to increase the flow of a main flow by the portion, angular motion loss of the main flow is caused when the flow toward the interior of the groove flows in the groove, because the inward flow has no revolution, and at outflow from the groove to the main flow, angular momentum of the main flow falls remarkably.
