Abstract: PROBLEM TO BE SOLVED: To prevent the marring of a spindle and a gripper due to their contact from occurring by installing the vertically moving spindle, and a spindle stopping a stopper guide and a stopper, all of which are vertically movable simultaneously, in a freely moving manner, when a perform is not supplied to the spindle. SOLUTION: When a preform P is not supplied onto a spindle 6, first the piston rod 20 of an air cylinder is actuated forward upon a signal from a photoelectric tube which detects the non-supply of the preform P. Further, a spindle regulating cam 18 is actuated forward from a state shown by a solid line to that by a broken line by the piston rod 20, and at the same time, a cam roll 17 is moved forward from a state shown by the solid line to that by the broken line to push a stopper 14 forward resisting a compression spring 15. Under this state, the spindle 6 and a spindle stopper 7 on a retaining member 4 ascend, resulting in the engagement of the spindle stopper 7 with the engagement groove 16 of the stopper 14 moved forward already, and thus the retaining member 4 is prevented from ascending.

Abstract: PURPOSE:To curtail a wiring miss and to curtail the manhour for designing a pattern around different lattice parts by generating virtual parts by regarding the corresponding hole as one pin parts and generating a net between said parts and a different lattice parts pin, in case of generating the corresponding hole and a leading-out pattern with respect to the different lattice parts pin. CONSTITUTION:From a net list, different lattice parts are selected, and virtual parts are generated by regarding the corresponding hole as one pin parts at every pin 34 of its parts and integrated into the net list. Subsequently, a net 31 containing the connection to a different lattice parts pin is selected, and the one pin parts are integrated into its net. As for the different lattice parts pin which does not exist in the net, namely, a free pin, a new net 32 between said pin and the one pin parts is generated and incorporated into the net list. In such a way, by incorporating the net between the one pin parts and the one pin parts into the net list, the corresponding hole 33 can also be handled in the same way as other general parts pin 35. Therefore, leading-out patterns 31, 32 can be designed without allowing a designer to be aware of them especially.

Abstract: PURPOSE:To previously avoid liquid return upon restarting by providing superheat degree altering means for obtaining larger suction superheat degree than suction superheat degree at the time of full load operation, at the time of partial load operation. CONSTITUTION:Superheat degree altering means 7 for obtaining larger suction superheat degree than that at a full load operation, at the time of partial load operation is provided.

Title: Polarization angle measuring instrument
Inventor: NISHINO NOBUHIRO
IPC: G02B27/28
Filed: 1986-05-21
Abstract: PURPOSE:To enable a timewise resolution to be improved and a polarization angle to be measured by spatially changing the rotational angle of a plane of polarization. CONSTITUTION:The title instrument is composed of a polarization plane rotator 1, a polarizing element 2 and a multichannel photodetector 3. Since, when a beam that has passed with polarization plane rotator 1 passes the polarizing element 2, the light wherein a polarization angle agrees with the plane of polarization of the polarizing element 2 passes the element 2 the most, output signals are obtained in the multichannel photodetector 3. The output signals represent the spatial distribution of the light quantity of the beam that has passed the polarizing element 2 and the angle of the polarization plane through which light incident upon a channel with the largest light quantity from a location on the multichannel photodetector 3 corresponding to the channel is rotated by the polarization plane rotator 1 can be calculated. By subtracting the angle from the polarization angle of the polarizing element 2, the initial polarization angle of the beam can be measured.

     CONSTITUTION: Gas G mixed with the same granular powder as granular powder in a fluid layer 2 is fed into the fluid layer 2 of a separation bath 3 through a transport pipe 1, which causes a decrease in gas speed and the fluid layer 2 to be mobilized. While gas G rises in the fluid layer 2, granular powder is caught in the fluid layer 2, separated to be accumulated in the separation bath 3 and flowed out through an overflow way. The gas G is conducted by a cyclone 6, and after residual granular pwder is separated and eliminated, it is exhausted from an outlet 7. Granular powder in the cyclone 6 is taken out from an overflow pipe 8.
