Title: Digital angle detecting method
Inventor: KUSHIHARA HIROSHI
IPC: G06G7/22
Filed: 1995-04-10
Abstract: PURPOSE: To obtain a digital angle output which has small influence of cable length, temperature variation, etc., by using a phase signal consisting of a composite resolver signal composed of a sin-side 1st resolver signal and a phase- shifted resolver signal generated by shifting the phase of a cos-side 2nd resolver signal by 90 deg. CONSTITUTION: A waveform shaper 23 shapes the waveform of a phase signal sinθ.sin(ωt-90 deg.-θ) as the composite resolver signal obtained by putting the 1st resolver signal sinθ.sinωt of a resolver 2 and the phase-shifted resolver signal cosθ.sin(ωt-90 deg.), obtained by shifting the phase of the 2nd resolver signal cosθ.sinωt by 90 deg. through a phase shifting circuit 31, together through an adder subtracter 22, and inputs the waveform-shaped signal as sampling pulses to a latch circuit 24. Then the phase count signal 21a outputted from a phase counter 21 is latched by a latch circuit 24 with the inputted sampling pulses and outputted as a digital angle output ϕthrough an output buffer circuit 40. Therefore, the stable digital angle output is obtained.

IPC: H03M1/36
Filed: 1988-04-05
Abstract: PURPOSE:To attain A-D conversion at a high speed with a few comparators by inverting a potential gradient across plural resistors having a resistance R and a resistor connected to one terminal of them having a resistance R/2, comparing the level by plural comparators, encoding the result and adding the result before and after the potential gradient. CONSTITUTION:An input voltage VX is compared with a comparison voltage obtained from a voltage division circuit consisting of resistors 3-5 having a resistance R and a resistor 6 whose resistance is R/2 at comparators 10-13. The output of the comparators 10-13 is converted into a binary number by a coder 14 and latched by a latch circuit 16. Then the input voltage VX is compared again by the comparators 10-13, and in this case, a switch 2 is thrown to the position of ground and a switch 7 is thrown to the position of reference voltage VR. The output of the comparators 10-13 is converted into a binary number by a coder 15, the outputs of the latch circuit 16 and the coder 15 are added by an adder 17 and a value subject to A-D conversion is obtained from an output terminal 19. Thus, high speed AD conversion is attained by a few comparators.

Title: Elevating rack device
Inventor: KOMAI SHOICHI
IPC: B65G1/137
Filed: 1985-04-20
Abstract: PURPOSE:To facilitate storage and carrying-out of work trays by equipping an elevating rack with a reference address and an additional address, by sensing the reference address while the rack is situated within the sensible scope of the reference sensor and by sensing the additional address using a subsensor while situated outside said scope. CONSTITUTION:The current address of an elevating rack 1B is perceived by a reference sensor 4 or subsensor 4, and the rack 1B is elevated or sunk. Reaching of a rack 14a to the position of a storage table 2A is perceived by the reference sensor 4 if it lies within the sensible scope so as to stop the elevating rack 1B, and the storage table 2A intrudes into the elevating rack 1B. In case a rack 20 reaches the position of rack 13, but the reference sensor 4 does not receive the reference address S1 because of outside the sensible scope, the subsensor 3 conducts perceiving. If at the same time the subsensor 3 perceives the added locational address S4, the elevating rack 1B is stopped to allow intrusion of a carryout table 2B into the elevating rack 1B. This simplifies the control circuit without requiring to switch the signal for each table to lead to facilitation of storage and carrying-out of work trays on the table.

Namely, the beam profile in the form in which the part of the large spot diameter is superposed on the part of the min. spot diameter is obtd. The optical head for overwriting which is small in the misalignment of the optical axis, facilitates the adjustment and has the high productivity is obtd. in this way and the control of the beam profile is extremely facilitated.
