Title: Data transmitter for numerical controller
Inventor: HIRABAYASHI TATEAKI
IPC: G05B19/418
Filed: 1983-11-30
Abstract: PURPOSE:To obtain a data transmitter which can cope with an unmanned operation for a long period of time or the fetching number of units of works, by editing a transmission sentence simultaneously with conversion of a memory language into an NC language through a transmission part within a CPU of a host computer. CONSTITUTION:A main program 21a is stored to a main program exclusive area 21 of an external memory 2 and then sent to the transmission part of a CPU1. While a subprogram 22a is stored to a subprogram exclusive area 22. When the program 22a is detected by retrieval, said transmission part edits a transmission sentence from both programs 21a and 22a excluding the key word part. The transmission sentence and all programs following the transmission procedure in said sentence are converted into code types to be transferred and then stored to a transfer file area 23. In this case, the code types are stored into a transmission data file 23a and a transmission procedure file 23b respectively. When a request is given for the NC data, the CPU1 transmits the data between main and subprogram areas while referring to the transmission procedure.

Title: Method and system for projection alignment
Inventor: NISHI TAKECHIKA
IPC: G03F9/00
Filed: 1998-08-10
Abstract: PROBLEM TO BE SOLVED: To detect a focal position without an offset by detecting in two or more directions variations in projection optical system in the direction of optical axis, which are produced at a plurality of points in a focal plane when a wafer is exposed to light. SOLUTION: A main controller 30 moves a wafer stage 9 in the Z-axial direction a defocusing amount ΔZ via a drive part 11, so that the detection value of a focal point in the exposure region of a wafer W which is detected by focus detection systems 31a, 31b at a predetermined position is changed by an amount of ΔZ. Further, a leveling stage 7 is slanted via a drive part 8 so that the detection values of the focal point in the directions of X and Y in the exposure region on the wafer W which are detected by horizontal position detection systems 32a, 32b agree with the amounts of inclination of surface Δθx, Δθy. This sets the reticle R and the exposure region on the wafer W in conjugate positions and prevents the occurrence of image defects caused by the curved surface of a projection lens 6 and the inclined image.  This is the end of focusing operation in the direction of Z.

Title: Fluid joint
Inventor: MORIMOTO YOSHIRO
IPC: F16D47/06
Filed: 1985-10-09
Abstract: PURPOSE:To prevent generation of noise and an obstruction to performance by extending an engaging arm outward from a turbine runner to arrange the friction connecting means for a pump impeller and a driven shaft on both sides in the shaft direction and providing an inclined face to engage with the engaging arm in the friction engaging arm. CONSTITUTION:An engaging arm 20a is formed in the radial direction of a turbine runner 20 and a couple of clutches 25, 26, whose inclined faces 25b, 26b having a nearly V letter shape are so formed as to be opposed to each other, are arranged on both sides in the shaft direction of said arm 20a, and then the inclined face 20b of the engaging arm 20a is engaged between those clutches. Hereupon the rotational torque of a driving shaft 12 acts upon clutches 25, 26 with a pushing force in the shaft direction by the engaging force components of respective inclined faces 20b, 25b, 26b and is transmitted to a driven shaft 22 but this pushing force increases when a slip is going to increase and an axial thrust force applied to the turbine runner 20 can be reduced nearly to zero. Consequently the generation of a confined sound in a car room and the performance deterioration can be prevented.

IPC: C23C28/04
Filed: 1988-09-09
Abstract: PURPOSE:To produce a sintered body coated with diamond excellent in resistance to peeling by plasmaizing and refining the surface of a base material made of a sintered WC body and thereafter forming a diamond film thereon. CONSTITUTION:Base material made of a sintered body having WC as a main component is arranged in a reaction vessel and the gaseous mixture of hydrogen and oxygen is introduced thereinto and the base material is plasmaized at 500-1200 deg.C to remove metal such as Co existing on the surface of the base material. Then diamond coating treatment is performed by a vapor phase synthesizing method and a refined surface layer made of recrystallized WC is formed in a range within at least 0.1mum toward the inside from the surface of the base material. A film made of diamond and diamondlike carbon is formed adjacently to this refined layer. Impurities are difficult-to be caused in the interface of the refined surface layer and this film. As a result, promoting action of nucleus formation of diamond is enhanced and thereby the dense and fine film is easily formed.

Abstract: PURPOSE:To suppress spurious radiation by inserting a high impedance line to a path sending the output of a prescaler to a voltage controlled oscillator, and providing a reference signal harmonic wave suppression circuit provided with a high frequency termination circuit. CONSTITUTION:Input and output terminals are provided with 50OMEGA lines 6, 7, and a high impedance line 8 is provided between the lines 6 and 7.

When an undesired wave close to 1GHz is inputted to the circuit, the wave is reflected at a high impedance line 8 and most waves are subject to 50OMEGA termination by a resistor 10 through the 50OMEGA line 9, only a DC component through a loop filter 4 is inputted to a voltage controlled oscillator(VCO) 1. Thus, a stable phase locked loop oscillation output whose spurious radiation is suppressed is obtained.

Abstract: PURPOSE:To automatically detect an abnormal waveform, etc., appearing in a signal waveform generated owing to a defect in wiring, etc., by inspecting a waveform state and a spike in an arithmetic processing controller by using a spike detecting signal. CONSTITUTION:A spike detecting signal generation part 7 consists of a circuit 7a which ANDs the inverted signal of, for example, a timing signal ti with an edge signal (e), an ST circuit 7b which inputs the circuit of the circuit 7a and outputs a sample timing ST signal alpha at a constant time delayed behind the edge of a signal waveform Dout, an SH circuit 7c which samples and holds (SH) the value of a waveform Dout at the point of time when the signal alphais received, and an A/D converter 7d which converts the value of the waveform Dout sampled by the circuit 7c from analog to digital. Consequently, the spike detecting signal from the generation part 7 is led to the arithmetic processing controller 3 and then compared with a reference value set previously therein to detect whether there is a spike or not and whether the current waveform state is normal or not from the value.
