Abstract: PURPOSE: To accurately process the irregular conductive thin film of the surface conduction electron emitting element at the high speed by processing the conductive thin film while a focal point against the surface of the conductive thin film is being adjusted based on information on the surface irregularities of the conductive thin film. CONSTITUTION: A specimen 12 is set in a XY direction scanning mechanism 11, and the output of a laser oscillator 1 is set to a desired value by a control computer 13. Control signals are sent to a position control mechanism 9 from the control computer 13 in such a way that the XY direction scanning mechanism 11 is moved in accordance with a processing pattern. A laser beam 1a for measuring irregularities on the surface of the specimen is projected into optical sensors 8a and 8b, and the position control mechanism 9 selects a signal out of signals from the two optical sensors while the drive direction of the XY direction scanning mechanism 11 is being recognized.  By this constitution, irregularities on the surface of the specimen is detected, and processing can thereby be carried out, in which each focal point of a laser beam 1b is aligned to irregularities on the surface of the specimen with an elevating mechanism 10 finely moved.

Title: Changing method of plate thickness in plate rolling
Inventor: FUJII YASUHARU
IPC: B21B37/24
Filed: 1981-04-10
Abstract: PURPOSE:To decrease the speed ratio changing degree as less as possible, by previously comparing the rolling speed ratio of a preceding plate thickness with that of a following plate thickness to find out a stand having the minimum speed ratio changing degree and using this stand as a pivot to change the speed ratio between the preceding and following stands. CONSTITUTION:A stand (the 3rd stand) that has the minimum speed changing degree is used as a pivot, and as a result the speed ratio is proportional to the speed ratioIof the previous size until the moment immediately before the time when the plate thickness changing point reaches the 2nd stand. The speed ratio between the 1st stand and the pass stand is set close to the speed ratio II of the pivot stand (the 3rd stand) every time the changing point of the plate thickness passes a stand after reaching the 2nd stand, and at the same time the above-mentioned speed ratio is set coincident with the speed ratio II of the following size. As a result, the speeds of all stands are changed every time the changing point of the plate thickness passes all stands excepting the 1st stand, and this changing degree is very small and does not exceeds the limit speed of each stand.

Accordingly, the As concentration of Ga liquid in the liquid pool 2a in contact with the substrate 4 or its saturation degree, is uniform; it means clean liquid not containing film or shell at the bottom. The remained part of the crystal 5a is perfectly separated with Ga liquid, and the crystals 5b to 5d are again contacted with each liquid contacted first. Thus, epitaxial layer less in deficiency can be obtained.

Abstract: PURPOSE: To make the tightening of a lockup nut perfect and make a freewheel hub compact, by engaging a plate not only with the brake shoe of a transmission and cut-off mechanism but also with the lockup nut.  
     CONSTITUTION: Lockup nuts 10, 11 for securing a bearing 9 are fitted on an axle pipe 1 so that a lockup washer 13 is interposed between the nuts 10, 11. A brake shoe 15 is coupled through a spring 16 to the roller cage 14 of a torque transmission and cut-off mechanism which includes an inner race 18, rollers 17 and a body 4. A plate 12, which slides in pressure contact woth the brake shoe 15, has inside square surfaces which are engaged with the lockup nut 10. The plate 12 is kept from rotating relative to the axle pipe 1. Since the rotation of the plate 12 relative to the pipe 1 is prevented by the lockup nut 10, space for the nut 10 is enlarged so that the nut can be perfectly tightened. This results in making the whole equipment compact.

Abstract: PROBLEM TO BE SOLVED: To suppress the variance in precision of constituting parts of a VCO (voltage controlled oscillator) and the shift of the oscillation frequency due to temperature deviation by correcting a control voltage given to the VCO so that it coincides with a reference voltage (design value). SOLUTION: If a control voltage Vc given to a VCO 10 from a loop filter 40 doesn't coincide with a reference voltage Vref, a correction voltage Va outputted from a correction voltage generation circuit 50 is nmpressed to the cathode side of a variable capacitor 15d in the VCO 10 to approximate the control voltage Vc to the reference voltage Vref and acts so as to keep the control voltage Vc fixed. Thus, the variance in precision of constituting parts of the VCO and the variance of the control voltage Vc due to temperature deviation are automatically corrected, and the control voltage Vc is made coincide with the reference voltage Vref as the design value, and the variance of characteristics as a PLL(phase locked loop) circuit is suppressed.
