Title: Method for monitoring damage degree of coated steel pipe and method for reducing erroneous judgment
Inventor: SHIBATA MUTSUMI
IPC: G01N27/20
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To prevent the erroneous judgment caused by noise by measuring the changes of pipe-to-earth potential and the output of corrosion-proof equipment and judging noise when the timing of these two changes and that of the change of damage resistance coicinde with each other or are received within a specified time. SOLUTION: A potential measuring device 11 and an in-pipe current measuring device 12 are connected to a transmission device 13 and potential data and in-pipe current data are transmitted to a computer 15 through the device 13 and a receiving device 14. The computer 15 measures potential through a potential (DC) measuring device 16 at a time of the measurement of damage resistance and also measures the output of corrosion-proof equipment simultaneously or independently and the timing of this potential (DC) and/or the output is compared with that of the change of damage resistance and, when both timings coincide with each other or are received within a specified time, it is judged that there is the effect of a noise current to neglect the damage resistance even if there is a change in the damage resistance.

Title: Motor control device
Inventor: YONEDA TAKAO
IPC: G05B19/19
Filed: 1993-03-26
Abstract: PURPOSE:To quickly execute the emergency stop of a motor when the motor starts to rotate in error by reducing an allowable positional deviation when the zero period of an objective speed is continued for more than a prescribed time. CONSTITUTION:A deviation between an objective position and a current position which is computed by a positional deviation computing means A is compared with an allowable positional deviation by a comparing means B, and when the deviation exceeds the allowable positional deviation, emergency stop is executed by an emergency stop means D. For the allowable positional deviation, a value theta1 stored in an allowable positional deviation storing means E at a standstill is used when the zero period of the objective speed is continued for more than the prescribed time, and in other cases, a value theta2 computed by a means F for computing the allowable positional deviation from the objective position is used. Since the value theta1 is smaller than the value theta2. the malfunction of the motor can be quickly detected and its emergency stop can be executed even when the motor in stopping starts to rotate in error.

Title: Refrigerating device for transportation service
Inventor: SUGIMOTO TAMIO
IPC: F25B27/00
Filed: 1992-04-13
Abstract: PURPOSE:To inhibit a rise in internal temperature during defrosting operation and prevent waste of fuel and reduce cost by installing an electro-magnetic clutch to a drive system which transmits engine power to either an evaporator fan or a condenser fan or both fans. CONSTITUTION:An electro-magnetic clutch 15 is installed to a drive shaft of an electric motor 2 which relays power of an engine 1 and transmits the power to an evaporator fan 12 and a condenser fan 8. During cooling operation, the power of the engine 1 is transmitted to each of the fans 12 and 8 by connecting the electro-magnetic clutch 15. On the other hand, during defrosting operation, the operation of each of the fans 12 and 18 is halted by disconnecting the electro-magnetic clutch 15. As a result, the air heated by the evaporator 11 remains only near an air outlet and it is not discharged inside easily, which makes it possible to inhibit a rise in the internal temperature and eliminate the need for a damper which opens and closes the air outlet. Since a condenser 7 is not cooled, it is possible to distribute enough amount of refrigerant to the evaporator and thereby prevent a drop in a defrosting capacity.

Title: Manufacture of grinding belt
Inventor: YANAGI YOSHIO
IPC: B24D11/06
Filed: 1987-04-15
Abstract: PURPOSE:To prevent abrasive grains from being detached, by performing the manufacture of a grinding belt applying to a belt base material the same tension to that applied to the grinding belt, when it is in use, so that the grinding belt prevents its under-applied adhesive agent from generating a crack when the grinding belt is in use. CONSTITUTION:Tension almost equal to the tension, applied to a grinding belt 1 when it is used, is applied to a strip-shaped belt base material 2, thereafter an under-applied adhesive agent 3 is applied in a stratified shape to surfaces of this belt base material 2. Abrasive grains 4 are uniformly distributed on a layer of this under-applied adhesive agent 3, and the grinding belt 1 is manufactured by fixing these abrasive grains 4 to the belt base material 2 by a finish-applied adhesive agent 5. Since the grinding belt 1 is used being manufactured applying tension such as in the above, the grinding belt 1, even if it applies the tension, only returns to a condition of the belt when it is manufactured, preventing the under-applied adhesive agent 3 from generating a crack. Accordingly, the grinding belt 1, preventing the abrasive grains 4 from being detached while holding the abrasive grains 4 to be distributed in a uniform condition even if the grinding belt 1 is pulled extending by the tension, the grinding ability is prevented from deteriorating.

Title: Contact signal input circuit
Inventor: INOUE MICHIYA
IPC: G05B15/02
Filed: 1986-04-22
Abstract: PURPOSE:To heighten an insulating characteristic, and to simplify a circuit constitution, by providing with an insulating transformer, a switch, a resistance, and a DC power source connected in series to the primary winding of the insulating transformer, and an AC power source, and a current detection circuit connected to the secondary winding of the transformer. CONSTITUTION:To the primary winding of an insulating transformer 2, a switch 1, a resistance R1, and a DC power source E are connected in series, and the values of the DC power source, and the R1 are decided so that a current on the primary winding generates the saturate state of the transformer 2 by turning on the switch 1. To the secondary winding, an AC power source V and the current detection circuit are connected in series, and the transformer 2 is not saturated in the off-state of the switch 1, and the current decided by the inductance of the transformer 2, and the voltage of the power source V, is permitted to flow on the transformer. The insulating transformer 2 is saturated by turning on of the switch 1. Consequently, the inductance of the transformer 2 in the secondary winding circuit is reduced, and the current on the secondary winding circuit is increased. Thus, by detecting the current on the secondary circuit, the on and the off states of the switch 1 can be detected. In this case, the good insulating characteristic of an input/output can be obtained because no photocoupler is used.
