Title: Motor driving circuit for reel turntable of tape recorder
Inventor: ITOU TADASHI
IPC: G11B15/32
Filed: 1980-05-21
Abstract: PURPOSE:To prevent a breakdown or the like trouble of a motor when the counter electromotive force is caused, by adding a limiting circuit that limits the current to be supplied to a reel turntable motor. CONSTITUTION:When a switch 7 is at the solid line side, the driving current is supplied to a motor 3a from a power source 6. Thus a reel turntable 2a is rotated via a rubber belt (rotational ratio converting/elastic means) 4a. Then a reel turntable 2b is rotated when the switch 7 is switched to the broken line side. The reel turntable is turned by the inertia in the direction opposite to the driving direction when the switch 7 is changed over. Thus an abnormal current flows to the motor. This abnormal current can be prevented by installing a limiting circuit 8 to limit the driving current which is supplied to motors 3a and 3b from the power source 6.

Title: Method for preventing explosion in drying system for organic waste
Inventor: FUJII TATSUHIRO
IPC: F26B21/06
Filed: 1982-04-22
Abstract: PURPOSE:To prevent the dust explosion of an organic waste, by a method wherein, based on a detected value of oxygen concentration, temperature or humidity of waste gas at an outlet of a dryer, a low temperature fluid is mixed in a high temperature waste gas at the inlet of the dryer. CONSTITUTION:A low temperature waste gas guide pipe 22 for guiding a low temperature waste gas in an waste gas circulating pipe 19 is connected to a middle of a high temperature waste gas guide pipe 11 for guiding a high temperature waste gas to a dryer (c) from an incinerator (a) (heat source) to detect either of an O2 concentration, temperature or humidity of waste gas at the outlet of the dryer (c). Based on the detected value, a control valve 23 located at a middle of a low temperature waste gas guide pipe 22 is controlled. This causes a low temperature waste gas to be mixed with high temperature waste gas in the incinerator (a) to reduce temperature of the gas at the inlet of the dryer (c) and also a partial pressure of residual O2 corresponding to its concn. in a high temperature waste gas, which results in evading a danger of dust explosion in the atmosphere in the dryer (c), and thus, a drying system may be reliably prevented from explosion.
