Title: Cryopump
Inventor: GOSHIMA MIKIHIKO
IPC: F04B37/08
Filed: 1981-12-26
Abstract: PURPOSE:To hold continuously the degree of vacuum in a vacuum container at a certain specific value, which is at or below the magnitude of order 10<-7> Torr, by such an arrangement that liquid helium is supplied to a liquid helium sump at any time from a depressurizing liquid helium sump. CONSTITUTION:If a liquid helium regulating valve 42 is opened little by little  using a valve opening adjuster 44, the liquid helium 20 stored in a liquid helium  sump 2 flows into a depressurizing liquid helium sump 41 through connecting  pipes 45, 46 by the action of the pressure difference, and the temperature of the  liquid helium 40 is held at a certain specific value, which is below 4.2 deg.K, to  allow non-exhausted gas particles in vacuum containers 1, 14 to condense fast  to the crio surface 41a so as to keep the degree of vacuum of the vacuum containers 1, 14 at a certain specific value below 10<-7> Torr. When the liquid helium  20 in the liquid helium sump 2 has decreased, liquid helium can be supplied at  any time without changing the pressure in the depressurizing liquid helium sump  41, so that the degree of vacuum in the vacuum containers 1, 14 can be maintained at the specified value below 10<-7> Torr continuously.

Title: Alarming device of shear pin cutting
Inventor: YAMAMOTO TOSHIROU
IPC: B21D1/05
Filed: 1983-11-14
Abstract: PURPOSE:To prevent cutting of a shear pin between a roll and an electric motor in advance by detecting load torque of a straightening roll of a rolling mill by current and number of rotation of an electric motor for roll driving and reporting overtorque by an alarming device such as a buzzer or an indication lamp. CONSTITUTION:The straightening roll 2 and its driving electric motor 1 of the steel plate rolling mill are connected by an intermediate shaft 3 having an interposed shear pin 4. Current of the electric motor 1 is measured by a shunt 7. Load torque of the roller 2 is calculated by an overtorque detector circuit 8. This is compared with rated torque for using shear pin, and when larger than the rated torque, it is judged as overtorque and detected. However, as acceleration torque and deceleration torque become necessary when the motor 1 accelerates and decelerates, rotation speed of the electric motor 1 is detected by a detector 6 and subtracted from above-mentioned comparison value. When it is judged as overtorque, an alarm is given by a buzzer 9, an indicator etc., and cutting of the shear pin 4 due to overtorque is prevented in advance.
