A roller frame supporting the shafts of the rollers 4 and 4 is fixed to the side frame of the main body 1 through a hinge. Thereby, the rollers are energized to always rotate in a lowering direction by dead weight. A lever with a lever handle 10a is provided at a lower part on one side of the main body 1 to make it possible to adjust the inclination of the roller frame. In addition, the load adjusting device consisting of a timing belt, a timing pulley, etc., is provided at the shafts of the rollers 4 and 4 to adjust by a load adjusting knob 33.  Thus, the load and inclination are adjusted to stabilize training.

IPC: G05B19/02
Filed: 1990-04-26
Abstract: PURPOSE:To minimize the manhour of turning back by forming sequence logic by using the general names of unit models even when tag numbers constituting each real unit are not determined. CONSTITUTION:A unit model to be defined is formed so as to include some supposed real units U1 to U3 including apparatuses or gages annexed to individual units or to be annexed in the future. The apparatuses or gages to be used for the units use general names, e.g. valves are VALVE1 to VALVE3 and an agitator is MOTOR, and a process control sequence or a unit sequence is formed while referring a unit model by using these names. Thereby, sequence logic can be formed prior to the determination of reuse or a real device of a program for process control or a unit sequence. Consequently, the manhour of turning back can be minimized and efficient engineering can be executed.

Abstract: PURPOSE:To provide variegated changes to the fountain shape by rotating a pressure equalizing tank provided with many water spray nozzles directed downward and provided on the circumference of the tank through a water supply rotary joint to add the velocity component caused by the rotation to the velocity of a water current. CONSTITUTION:An AC power at 100V is supplied from a power source connector 12 to drive a motor pump 3 for a fountain, and the supply of water is started.

Title: Low boiling point medium turbine
Inventor: ISHIDA MAKOTO
IPC: F01D17/08
Filed: 1984-05-31
Abstract: PURPOSE:To prevent the output of a turbine from lowering, which is used in an electrical facility composed of a Rankine cycle system and which has a plurality of main steam pipes, by disengageably coupling the root sections of turbine blades to a rotor. CONSTITUTION:When the temperature of a high-temperature heat source lowers below a designed value, main steam flows into a turbine through a second steam pipe 4. At this time a coupling ring 10 slides to a position where it does not oppose a first stage blade root section 7a, and is fixed to a rotor 1 with bolts 23. Accordingly, a main steam works through second state blades 9, and discharged from an exhaust pipe 5. At this time blades 7 in a high pressure stage are stationary while the coupling ring 10 is alone rotated, and therefore, it is possible to avoid the lowering of the efficiency of the turbine due to the racing of turbine blades, etc.
