Title: Magnetic recording and reproducing unit
Inventor: SATOU MASAAKI
IPC: G11B15/00
Filed: 1979-04-04
Abstract: PURPOSE: To prevent static electricity caused on the magnetic tape, by forming the pinch roller shaft and bearing with conductive metal and forming the pinch roller with conductive rubber.  
     CONSTITUTION: The pinch roller 16 is formed with the conductive rubber fitted on the external circumference of the conductive shaft 30 such as arbor bolted on the conductive bearing 28. Since the pinch roller 16 is formed with conductive rubber, even if static electricity is caused on the base 32 of the magnetic tape 14 and the magnetic film 34, the static electricity is grounded to the main body via the conductive pinch roller 16, conductive shaft 30, conductive bearing 28 and pinch roller lever 36 from the magnetic film 34. Accordingly, the charging of the static electricity on the magnetic tape can be prevented.

Abstract: PURPOSE:To provide the titled system enabling both equipment and service costs to be reduced, not requiring agitator and crude grinder, so specifically constituted as to rotate a highly viscous melt in hopper by jet action of cooling water and be capable of simultaneous crude grinding and cooling of the resultant solidified product. CONSTITUTION:First, a highly viscous melt such as tar is fed from a melt feed opening 2 to a melt feed hopper 1. Second, cooling water is jetted through a nozzle 12 fitted at cooling water feed opening 3 in the peripheral direction of the hopper 1 to convert said melt into a semi-solidified product such that the surface is solidified but inner phase unsolidified; whereas the water vapor produced by contact between the melt and cooling water is exhausted through a vent 4. Following that, said semi-solidified product together with the cooling water is fed, through a connecting section 5, to a cooling tank 6, being made to descend in the tank 6 while impringing against a baffle 7 to effect crude grinding and complete solidification. Finally, the resulting solidified product is separated from the cooling water using a separator 8, being drawn out through a line 22, whereas the cooling water is returned to a receiving tank 10.

Filed: 1983-03-11
Abstract: PURPOSE:To facilitate checking operations of various detecting switches, by a construction wherein whether or not the operations of a plurality of detecting switches for detecting information on the condition of an engine are normal can be checked at a checking terminal. CONSTITUTION:After a key switch is turned ON, when an accelerator pedal is depressed and with the result that the opening of the throttle valve exceeds a predetermined value alpha and an idle switch 1 is turned ON, a transistor Tr1 is turned OFF, and the potential at a point (a) is raised to a high level. At this time, since a WOT switch 4 for detecting the full opening of the throttle valve remains OFF, an output from an AND circuit 6 is at a low level, a transistor Tr3 is turned ON through an inverter IN, and a voltage of 0V is measured at the checking terminal 7. When the switch 4 is subsequently turned ON, the output from the AND circuit 6 becomes high level, and a voltage VB is measured at the terminal 7. In this case, when the switch 1 and/or the switch 4 is in an abnormal condition, the transistors Tr1, Tr2 remain ON, and a voltage of 0V is measured at the terminal 7.
