Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of computations and the interval between measurements by dividing the corresponding relationship between a measurement region and the position on the optical system to be measured into the corresponding relationship between a parallel movement and a magnification and a rotational movement and computing tilt measurement values, tilt functional values and coefficients among these relationships. SOLUTION: When an image is inputted from an imaging device 44, an arithmetic unit 45A computes the amount of parallel movement and the magnification of the image of each lens of a lens array 43 and a main mirror 1 based on each focal distance of devices and position information (455) and the corresponding relationship between each lens and the region on the mirror 1 is established. Then, the amount of tilt error of the wave front is computed from the amount of the deviation of the image formation points on the imaging surface of a reference light beam 49 and a reflected light beam 48 (452), the tilt function average value in each measurement region 'i' on the mirror 1 corresponding to each lens is computed (452) and extension coefficients are estimated (453).  Then, the rotation angles of the array 43 and the main mirror image are computed based on the rotation angle information from a visual field rotation compensation device (456), rotational compensations are added to the coefficients in accordance with the angle and a wave front deformation is computed (454).

Abstract: PURPOSE:To enable a selection only by the measurement of oscillation frequency by constituting the titled transistor by an LC oscillation circuit using capacitance between a gate and a source as at least one part of tuning capacitance on the basis of a view to the effect that there exists a proportional relationship in capacitance between the gate and the source in the GaAs-FET and a noise index of the FET. CONSTITUTION:A series circuit consisting of a three stub-tuner 4a, an isolator 3a and a noise generator 2 and a series circuit consisting of a three stub-tuner 4b, an isolator 3b and a mixer 5 are each connected on both sides of an evaluating mount 1 to which an element to be measured is set up while holding the evaluating mount 1. Both ends of these circuits are connected to a noise figure meter 7, and a partial oscillator 6 is connected previously to the mixer 5. According to such constitution, capacitance can be evaluated only by a capacity meter because it is confirmed that a noise figure of a GaAs-FET is evaluated but there is proportional relationship between capacitance between a gate and a source in the FET and the noise figure.

Abstract: PURPOSE:To elevate a processing capacity and also to get rid of an error of a readout information, by executing an access processing in paralle, when an actual address space which has been made multiple by plural memory units has been accessed simultaneously from plural memory control parts. CONSTITUTION:In case of a readout access to an actual address space 12, if memory control parts MCU 5,6 do not access a memory unit 7, only an AND gate 20 outputs ''1'', and selects and accesses the unit 7. In case of a write-in access to an actual address belonging to the space 12, since outputs of NAND gates 23-25 and OR gates 31, 32 are all ''1'', when AND gates 17-19 are ''1'', the respective corresponding gates 20-22 become ''1'' immediately. Therefore, write-in access can be executed simultaneously to all the memory units that are not accessed from other control part MCU, among memory units 7-9.

Title: Continuous casting method
Inventor: YAMAUCHI HIDEKI
IPC: B22D11/10
Filed: 1980-07-10
Abstract: PURPOSE: To produce ingot having sound surface characteristics smoothly and continuously by blowing hydrocarbon into a gap between a mold and a ingot.  
     CONSTITUTION: Molten steel is introduced into a water-cooled mold 1, and an ingot 4 is continuously drawn from below the mold 1. Porous refractory bodies 2 are arranged at the bottom end of the mold 1. Hydrocarbon gas, for example, propane  is introduced through said porous refractory bodies 2 inro the gap 5 between the  ingot 4 and the mold 1. The decomposition carbon generated by the decomposition  of hydrocarbon has the lubricant effect. The heat absorption due to the decomposition of hydrocarbon serves as a cooling means for the gap. The forced introduction  of hydrocarbon gas causes a forced convection in the gap which permits uniform  cooling in the inside of the gap of the mold. The above operation permits to draw  the cast product smoothly and make the surface of the ingot smooth and beautiful.

Title: Time-division fm radar system
IPC: G01S7/02
Filed: 1992-03-19
Abstract: PURPOSE:To reduce power consumption by distributing an FM signal to a plurality of transmission/reception channels while amplifying it by an intermittently operating amplification/division circuit. CONSTITUTION:In a configuration of one channel of a plurality of amplification/ distribution circuits constituting a radar system, a timing signal which intermittently rises high is supplied to an input terminal I5 from a timing control circuit so that switching transistors Q2, Q1 are intermittently ON. Accordingly bias voltage of an input terminal I4 is supplied to the FETs Q1, Q2 as drain voltage so that both are intermittently operating. An FM signal supplied to an input terminal I2 is amplified by FETs S1, S2 and supplied through an output terminal O to a rear stage circuit 116a. Though as many amplification/distribution circuits are required as the number of channels (N), they intermittently operate only when the FM signal is distributed to the corresponding channel reducing an individual operating time rate to 1/N, thereby reducing power consumption.
