Title: Method and device for polarization diversity optical reception
Inventor: TSUSHIMA HIDEAKI
IPC: H04B10/58
Filed: 1987-03-13
Abstract: PURPOSE:To enable to receive a PSK optical signal, to heighten sensitivity, and to simplify the constitution of an optimum threshold value setting circuit, by adding two intermediate frequency signals obtained by heterodyne-detecting two polarized components crossing orthogonally of an optical signal after delaying and detecting them respectively. CONSTITUTION:The intermediate frequency signals 3X and 3Y obtained by applying the heterodyne light detection of the two polarized components crossing orthogonally of the optical signal become inputs to delay detectors 1x and 1y respectively. The intermediate frequency signal 3X is branched to two signals 7x1 and 7x2 by a branching filter 6x. Next, the signal 7x2 receives appropriate delay by a delay line 8x. Therefore, a delay time difference (tau) exists between the signals 7x1 and 7x2 to be inputted to a multiplier 9x. A signal 10x outputted from the multiplier 9x is low-pass-filtered at a low-pass filter 11x, then, it becomes a signal 4x. The same operation is applied on the intermediate frequency signal 3Y, then, a signal 4y can be obtained. The signals 4x and 4y are added at an adder 2, and a signal 5 is outputted. The signal 5 does not depend on the polarized state of the optical signal. Also, the above operation can be realized even by removing a low-pass filter 11 from the delay detector, but, in this case, low-pass filtering is performed after adding the signals 10x and 10y.

Dosage, depending upon the implanting energy, is normally selected from a range above 10<11>cm<-2>. Then, ions which are diner impurity, such as Si, Se, S, Te are implanted to form an N-type active laeyr 2 and an N<+> type layer 6. At this time, the energy and the dosage are selected to from ranges of 30-200keV and 10<11>-10<13>cm<-2>. Thus, carrier magnification when alpha-ray is incident can be eliminated, and a semiconductor memory is formed of the transistor of this structure to prevent a software error from occurring due to the alpha-ray.

Abstract: PURPOSE:To improve slurry transportation greatly by controlling the amount of fresh supply water corresponding to the amount of slurry discharged from a mixing tank, and thus maintaining the slurry concentration on the suction side of a slurry pump at a set value all the time. CONSTITUTION:When solid slurries are discharged from the opening of a mixing tank 6 in quantities, the slurry concentration of a suction pipe 7 increases above a set valve.

IPC: G01N11/16
Filed: 1989-03-09
Abstract: PURPOSE:To judge coagulation and fermentation states of a material in a cup by applying a freely attenuating vibration to the sealed cup to analyze a data of a vibration phenomenon automatically. CONSTITUTION:A cup 1 holding contents such as yogurt or the like is placed on a top plate 2 and a torsional vibration is applied to the top plate 2 with a torsional spring 3. Then, the torsional vibration is detected hourly with a sensor 4 to be inputted into a data processor 6 through an amplifier 5. The processor 6 measures a cycle, a frequency and an amplitude of a freely attenuating vibration of the cup to determine a logarithmic attenuation factor of the amplitude and calculates a viscous resistance based on a specified formula. Then, based on an increase or decrease in the frequency and a change in the viscous resistance, a solidification or fluidization state of the contents is judged. This enables judgment of a coagulation and fermentation states of a fermenting material without opening the cup.
