IPC: H01L31/09
Filed: 1981-06-23
Abstract: PURPOSE: To improve the yield of production of photodetectors by fitting another opposed electrodes for bit compensation in parallel with ordinary opposed electrodes.  
     CONSTITUTION: A film of photosemiconductor 4 is applied to the surface of electrodes 2 formed on a substrate like a pattern and then opposed electrodes 3 (3-1, 3-2,...) are applied to the surface of the photosemiconductor 4. In this configuration, real photodetectors are formed on parts in which the electrodes 2 and opposed electrodes 3 are crossed each other. Several lines similar to said opposed electrodes are formed on the substrate so as to be apparently formed one-dimensional photodetectors corresponding to several photodetectors to use them for bit compensation. Subsequently a power source line 1 and the opposed electrode 3-1 are connected to check the photodetectors on the line of the opposed electrode 3-1. If a defective part is detected on the line of the opposed electrode 3-1, the line between the power source line 1 and the opposed electrode 3-1 is disconnected. Subsequently the power source 1 and the succeeding opposed electrode 3-2 are connected to be tested. Thus, the yield of the photodetectors is improved by checking each line successively to use complete lines.

Title: Multifunctional earphone set
Inventor: KIMURA HIROFUMI
IPC: H04B1/38
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To suppress the influence on a simultaneous transmission and reception discriminating function by increasing the effective resistance values of transformers for conversion and cancellation and reducing the influence due to the variance of the lead wire resistance value. SOLUTION: An impedance element is used as a receiving coil K2 on the side of the transformer T1 for conversion and connected to a 3rd transformer T3 in a cross state. Further, the secondary coil K4 on the side of the transformer T2 for cancellation is connected to the 3rd transformer T3 is parallel. Here, the resistance value of the 3rd transformer T3 can be set up to 300Ω, if resistance values of both the transformers T1 and T2 are set to 100Ω and the variance of the resistance value of a lead wire is set to 20Ω, the effective resistance value of both the transformers T1 and T2 become 400Ω. Therefore, the degree of influence due to the 20Ω variance of the resistance value of the lead wire becomes 5%, or a quarter as large as that of conventional technology.  Thus, the effective resistance values of the transformer for conversion and transformer for cancellation are increased to greatly decrease the degree of influence even if there is the variance of the resistance value of the lead wire, thereby greatly suppressing the influence on the simultaneous transmission and reception discriminating function.

Title: Method and device for calculating particle transportation, device for monitoring reactor core characteristic of reactor, and nuclear power station
Inventor: MORIWAKI MASANAO
IPC: G21C17/00
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To greatly improve calculation speed in the correlation sampling Monte Carlo method by taking in virtual scattering in a transportation equation. SOLUTION: First, at the initial stage of combustion, a normal Monte Carlo calculation is executed, and sampling information is calculated while analyzing nuclear characteristics and is retained on a memory. In the Monte Carlo calculation, virtual scattering is used. Then, the degree of combustion is updated and the number density of each nuclide is calculated, and a new macro sectional area is calculated. More specifically, the weight of a neutron is adjusted from a current macro sectional area and a retained reference system macro sectional area, based on sampling information, thus solving nuclear characteristics and hence drastically reducing the analysis time of particle transportation by the correlation sampling Monte Carlo method. The method can also be applied the time-series calculation of the operation schedule calculation of the reactor.
