Title: Vane back pressure applying device for sliding vane type compressor
Inventor: HASEGAKI TAKAHIRO
IPC: F04C18/344
Filed: 1985-09-06
Abstract: PURPOSE:To prevent malfunction of a vane and incomplete compression at start of a vane type compressor by feeding gas in a high pressure chamber into a vane back pressure chamber when starting under such condition as the differential pressure between high and low pressure sides is low. CONSTITUTION:Upon start of compressor under such condition as the differential pressure between high and low pressure sides is low, a vane 4 will spring out to lower the pressure in a vane back pressure chamber 17. Consequently, gaseous fluid will flow through a gas supply path 27 opening above a high pressure chamber 14 thus to assist spring out of the vane 4. Upon elapse of some interval, the differential pressure between high and low pressure sides will increase thus to increase the flow of gaseous fluid flowing from a path 31 through a first gas supply path 27 and to increase the hydraulic pressure to be applied onto a valve body 30. Consequently, the valve body 30 will seat in a valve seat 29 to interrupt between the path 21 and the gas supply path 27 thus to feed only high pressure oil in the oil path 18 into the vane back pressure chamber 17.

The signal (i) is prepared by two integrated circuits 6-7, a comparator A4, an edge extraction circuit, etc., at that time. Accordingly, driving currents made to flow through respective driving coil Lu-Lw are changed over by the transistors Q1-Q6 of a driving-current changeover circuit 2.

Abstract: PURPOSE:To prevent water absorbtive damage of a non-linear optical crystal and cavity loss by a method wherein a non-linear optical crystal is housed in a container, an incidence window also serving as a mirror is disposed on the laser incidence side of this container, and an outgoing window also serving as a mirror is disposed on the laser outgoing side thereof. CONSTITUTION:When a third higher harmonic laser beam of a Nd-YAG laser is inputted as pumping light 8, pumping light 10 formed of signals and idlers is generated by light parametric oscillation. When the incidence angle of the pumping light 8 with respect to the crystal axis is changed as a result of rotating a non-linear optical crystal 5 in the direction of the arrow about a central axis 6 by means of a stepping motor 14, the wavelength of the pumping light 10 changes continuously in a fixed range. When the wavelength of the pumping light 10 is changed, only the non-linear optical crystal 5 is rotated while a container 3 remains fixed. In this case, an incidence window 41 also serving as a mirror and an outgoing window 42 also serving as a mirror are adjusted by screws 55, 56, 57 and 58 for adjusting flapping in the X and/or Y axis so that laser which oscillates between cavities makes an amplification function more effectively.
