Abstract: PURPOSE:To reduce a slackening phenomenon in summertime and to wind a sheet into a roll form by thinning a slip layer by stacking a polyolefinic film, a metal vapor deposition layer, a specific asphalt composition layer and, if necessary, a release layer in this order. CONSTITUTION:A slip layer sheet is formed by laminating a polyolefinic film 6, a metal vapor deposition layer 5, an asphalt composition layer 3 and a release layer 1 provided if necessary in this order. The softening point of the asphalt composition is set to 60 deg.C or less and the penetration thereof is set to 80 or more (measured at 25 deg.C). Herein, a synthetic resin layer composed of polyethylene terephthalate or polyolefin may be provided between the metal vapor deposition layer 5 and the asphalt composition layer 3. By this method, the thickness of the slip layer 3 can be reduced and the sheet can be stored or transported in a state wound into a roll form and, further, said sheet generates no slackening even in summertime.

Title: Shaft height measuring instrument
Inventor: OTAKE FUMIO
IPC: B23Q17/22
Filed: 1985-09-28
Abstract: PURPOSE:To improve the efficiency of measuring operation by using a turntable and decreasing the frequency of replacement of a jig. CONSTITUTION:Respective inspecting and measuring jigs corresponding to a couple of shaft body works W which constitute a specific speed reduction gear, etc., are mounted and supported on respective jig fitting bases 25 and the respectively works W are supported on the respective jigs 28 so that lower measurement surfaces W1 abut on abutting surfaces 28a. Those respective works W are indexed to a measurement station MS in order through the rotation of the turntable 20 and an inspecting and measuring gauge 27 corresponding to a work W is mounted on a measuring head 30 at every time. Then, the head 30 is lowered until the gauge surface 37a abuts on an upper measurement surface W2, so that the shaft height between both measurement surfaces W1 and W2 of each work W is measured successively. Then, when a couple of works W to be measured next are equal in specification, the respective jigs 28 on the respective fitting bases 25 are unchanged and the next couple of works W are supported to measure the shaft height. Thus, when the specification of the works W is unchanged, they are measured without replacing any jigs 2 and even when the specification is different, that is easily dealt with by replacing the jigs 28.

Title: Converter of copying motion into numerical information
Inventor: MATSUI MITSUO
IPC: G05B19/4097
Filed: 1983-11-19
Abstract: PURPOSE:To avoid an overhang or cut-in phenomenon for a converter which converts a copying action into the numerical information, by reducing the table traveling speed after deciding a deceleration area in a copying motion mode and putting the deceleration command information into the output position information. CONSTITUTION:A controller 17 drives motors MX-MZ so that a stylus 3 has a fixed level of contact pressure to the surface of a model 1. Then a table 7 is moved to make the stylus 3 copy after the surface of the model 1. A limit switch drive bar 32 turns on a limit switch 30 when it is detected while the table 7 is moving toward an axis (x) and then turns off the switch 30 when it is detected while the table 7 is moving in the opposite direction to the axis (x). While a limit switch bar 34 has an action reverse to the bar 32 and is therefore kept on while the switch 30 is set between both bars 32 and 34. A deceleration area deciding circuit delivers the deceleration command information when the switch 30 is turned on and then delivers the release information when the switch 30 is turned off. Thus, an overhang or cut-in phenomenon is prevented.
