Filed: 1990-06-29
Abstract: PURPOSE:To achieve higher toughness against noises by a method wherein rising and falling edges of a square wave are checked and a phase of a desired wave with respective edges in checked from positive and negative section time to detect a frequency component of the desired wave is detected. CONSTITUTION:Time of a timer latch at a positive section TH is set to TWA and an edge polarity is to POL. When the TWA is less than TPA for which a 1/4 of a desired wave A is set initially, the residual time is set to TPA. Then, at the next rising edge, time of a negative section is set to the TWA while at the falling edge, that of a positive section thereto. Then, when the TWA is larger than or equal to the TPA, the residual time TPA is added to or subtracted from TIA according to an edge polarity POL. A time difference between the positive and negative sections of a square wave at the 1/4 cycle of the desired wave is set for the TIA. A difference of sinPSI integrated values between both the sections is detected as a value of a frequency component of the desired wave.

Title: Dpsk phase deviation detection circuit
Inventor: NAKAGAWA MIKI
IPC: H04L27/20
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To allow the circuit to accurately detect a phase deviation in differential phase shift keying(DPSK) modulation. SOLUTION: A monitor circuit 7 compares an output voltage of a mixer 4, in the case of DPSK modulation in a 0-status with a mixer output voltage in the case of π-status, to detect a phase deviation in the case of π-status. On the other hand, offset detection circuit 8 monitors an output voltage of the mixer 4, when DPSK modulation denotes 0-status to detect an offset, so as to change a phase shift of a programmable phase shifter 9 depending on the detected offset. Thus, the phase deviation in the DPSK modulation is detected accurately for all operating frequencies.

Title: Pattern forming method
Inventor: HAYANO KATSUYA
IPC: G03F1/68
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To prevent an outermost pattern of a pattern group from non-opening and to obtain a larger margin for a lithography process by enlarging the outermost circumferential pattern of a periodically arranged pattern group for an arrangement. SOLUTION: Dimensions of an outermost circumferential pattern 56 of a periodically arranged pattern group 53-56 are enlarged. In a light intensity distribution in the discontinuous direction A-A' of the periodically arranged pattern 53, an effect of a deformation illumination method is obtained and also an excellent light intensity profile is obtained. In a light intensity distribution of the discontinuous direction B-B' of the pattern 56, the dimensions W' are designed larger than those W of the periodically arranged patterns 53-55 for an arrangement, therefore, it is possible to suppress deterioration of the light intensity. Thus, a hole pattern can be formed with a sufficient non-opening margin.  Especially, microfabrication and micro-arrangement of the hole pattern for leading electrodes of super LSI, of which microfabrication is especially difficult, can be achieved and production of super LSI can be achieved by using optical lithography.
