Title: Numerical controller
Inventor: FUJIWARA KOJI
IPC: G05B19/4103
Filed: 1991-04-02
Abstract: PURPOSE:To rapidly process distribution pulses applied to residual spindles of a tool especially at every program block in a numerical controller for controlling a machine tool such as a laser working machine. CONSTITUTION:An excess distribution variable S read out at the time of ending each program block is computed prior to its execution. An addition value commanding means 3 divides the variable S by an optionally set addition value N and the divided result is added to its preceding distribution variable having a preceding distribution period. Thereby, the excess distribution variable commanded from an acceleration/deceleration control circuit 4 always becomes zero and the reduction of a speed between blocks can be prevented.

Title: Quartz glass member for photolithography
Inventor: HIRAIWA HIROYUKI
IPC: G03F1/60
Filed: 1993-04-23
Abstract: PURPOSE:To make it possible to obtain fine and bright patterns by cofining the RMS (root mean square) value of wave front aberrations to a specific value or below after power component correction. CONSTITUTION:The RMS value (after the power component correction) of the wave front aberration expresses only the component to directly affect optical performance and, therefore, the surer assurance of the optical performance is possible. Namely, the RMS (root mean square) value is calculated by using all measurement points and, therefore, its information quantity is large and is hardly affected by measurement errors. Statistical processing is possible as well. The RMS value of the wave front aberrations after the power component correction is, thereupon, used and is so adjusted that this value attains <=0.015. This upper limit is simulated by taking the various aberrations to be generated by the influence of the respective components of a refractive index analysis excluding the power components into consideration and is determined as the value at which the performance of a projecting lens is exhibited. Aberrations are increased and the member is no longer adequate as a member for photolithography if the RMS value is >=0.015.

Title: Vibration reducing device for stirling engine
Inventor: FURUISHI YOSHIO
IPC: F02G1/043
Filed: 1987-04-20
Abstract: PURPOSE:To reduce vibration of a Stirling engine and to accomplish silent operation by detecting the inertia unbalanced force generated by a direct-acting driving portion of an engine and providing a damping actuator for generating damping force to cancel the inertia unbalanced force. CONSTITUTION:A vibration sensor 29 detects the vibrational acceleration generated at a direct-acting driving portion such as a power piston 18, a yoke 23b and the like to output it to a control circuit 30. The control circuit 30 which has received the above detection signal computes according to a designated control law for inverting the phases of the damping force generated by a damping actuator 28 and the inertia unbalanced force of the direct-acting driving portion to cancel each other and outputs a driving current to the damping actuator 28. Consequently, the damping force for cancelling the inertia unbalanced force of the direct-acting driving portion is generated by a damping force generating portion 28c. Accordingly, the vibration of a Stirling engine can be reduced to enable silent operation.

CONSTITUTION:While the synthetic resin hose C with necessary dimension and wall-thickness whose outer periphery is covered with a reinforcing net N, is introduced in an extruding mold 3 and is extruded at a predetermined speed, a rotary body 7 is turned in the state where said turning is fitted to the pitch of the rib L formed integrally on the outer periphery of the hose in the corresponding relation to said extrusion speed. The thermoplastic synthetic resin in molten state is extruded into the material-feeding path 4 of the extruding mold 3 by necessary feeding amount and pressure with a first extruder. Consequently, the inside of the extruding mold is brought in close contact with the outer periphery of the extruded hose, and the resin is made integral with the hose so as to enclose the net. Simultaneously, when the material which becomes the rib is fed in the material-feeding path 13 by a second extruder, the semi-molten resin material is extruded into a rib-shape from the nozzle exit 9b of a rib nozzle 9 fitted to the tip through a rotary body from the path 13, thereby forming the rib L integrally.

Formation of monoclinical zirconia crystals increases if the ratio of the CeO2 is below 10mol.% in this sliding member. The degraded mechanical strength, easier tendency to deterioration with lapse of time and the degraded wear resistance are then caused. Formation of cubic zirconia crystals increases if the ratio of the Cr2O3 exceeds 20mol.%. The easier tendency to dislodgement of the crystal particles and the degraded mechanical strength and sliding characteristic are then caused. Seizure is liable to arise if the ratio of the zirconia component exceeds 95% and the ratio of the Al2O3, etc., is below 5%. The wear of the mating material increases and the coefft. of friction increases if the ratio of the zirconia component is below 50% and the ratio of the Al2O3, etc., exceeds 50%.
