Title: Intermittent feed controller
Inventor: SUGAWARA KAZUNORI
IPC: G05D5/00
Filed: 1980-04-07
Abstract: PURPOSE: To enable the feed of a sheet only by fixed length by a method wherein the amount of slippage in the case when the sheet delivered from a winding roll is stopped is measured, the length of the sheet fed is substracted and corrected only by the amount of slippage and a point of time when stopping signals are output is controlled.  
     CONSTITUTION: The length of a sheet fed is inputted to a preset counter 14 and a slippage amount counter 15 from a signal generator 13, and the preset counter 14 counts the calculation of input signals, and generates stopping signals to a drive roller 5 when a fixed value is counted. The slippage amount counter 15 measures the amount of the slippage of the sheet on the basis of the stopping signals. The amount of slippage is inputted to a subtractor 17, and subtracted from the set value of a feed length setter 16. The result of the subtraction is inputted to the preset counter 14, and set to a novel value. Thus, the sheet can be fed at all times only by fixed length by correcting the amount of slippage.

Title: Sealed and motored compressor
Inventor: FUJISAKI SHIYUUJI
IPC: F04B49/10
Filed: 1979-04-12
Abstract: PURPOSE: To inhibit operation of a compressor apparatus exactly under lack of lubricating oil by using opposed electrodes in lubricating oil as a oil level detecting condensor.  
     CONSTITUTION: Adding condensors represented by C 1 WC 3  in the drawing completes a bridge circuit. The capacities of the condensors C formed between opposed electrodes 5, 5' are balanced when a level of lubricating oil 2 exceeds a level H of minimum requirement. In case of the excess, an output l 0  of a modulator S is zero and an auxiliary relay 10 is off, which causes an electromagnetic contact 9 ON to throw the compressor apparatus 8 into operation. When a level of lubricating oil 2 is lower than the level H, those capacities of the condensors in the bridge circuit are unbalanced to stop the operation of the compressor apparatus 8. That effect may inhibit operation under lack of lubricating oil and prevent the sliding faces from burning.

Abstract: PURPOSE:To give a surface roughness of necessary minimum to secure a video characteristic to and also to impprove the wear resistance of a magnetic recording medium by installing a back coat layer containing spherical zinc oxide powder having a specific mean grain size to the back of the base. CONSTITUTION:A back coat layer containing 60-99wt% of spherical zinc oxide powder having a mean grain size of <=0.15mu and 1-40wt% of zinc oxide powder having a mean grain size of 0.16-1.5mu, is installed to the back of a base, to the main surface of which a magnetic layer is formed. The zinc oxide powder of <=0.15mu is manufactured after a wet method, has a spherical shape and small diameter, and well disperse into various kinds of binders in the back coat layer. Moreover, the powder is relatively soft, being about 4 in Mohs' hardness. The zinc oxide powder of 0.16-1.5mu can prevent occurrence of worn out of the magnetic recording medium using this zinc oxide powder when the medium is contacted with and slid on a VTR guide, etc. Therefore, the magnetic recording medium using these zinc oxide powders can secure the running stability and video characteristic and, at the same time, can have a back coat layer which is excellent in resistance to wear. The back coat layer is formed by applying a coating material which is prepared by mixing and dispersing the zinc oxide powders into a binder to the back of a base, to the main surface of which a magnetic layer is formed in advance. The applying thickness of the powders is usually set at 0.5-30mu.
