Title: Light attenuator and its production
Inventor: KATO KUNIHARU
IPC: G02B6/00
Filed: 1994-11-11
Abstract: PURPOSE: To obtain a constant attenuation quantity regardless of wavelengths of light signals by eliminating the wavelength-dependency of a light attenuator using dopants. CONSTITUTION: An optical fiber of a mode field diameter most suitable to the wavelengths of the light signals to be transmitted is obtd. by adjusting the refractive index distribution and core diameter, etc., of a single mode fiber. The light signal of the shorter wavelength receives the higher attenuation than the light signal of the longer wavelength if the mode field diameter is so selected as to be adaptable to the light signal of the longer wavelength out of the light signals of two kinds of the wavelengths to be inputted to the light attenuator. On the other hand, the dependency of the light attenuation characteristic on the wavelengths occurring in the selection of the mode field diameter is offset if the dopant to more largely attenuate the transmitted light of the longer wavelength of the light signals is incorporated into the optical fiber 5 shown in the Fig.  As a result, the light attenuation characteristics to the light signals of >=2 kinds of the different wavelengths λ1, λ2 are made nearly equal to each other.

Title: Forgeryproof prepaid card
Inventor: TOYAMA YASUHIRO
IPC: B42D15/10
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To enable the frequency of using a prepaid card to be checked through the switching of a continuity state to a non-continuity state due to a cutoff when the card is used by providing continuity lines for checkup. SOLUTION: A pattern film is created by patterning continuity lines 1-9. In this case, a continuity terminal for checkup is provided for the continuity lines 1-9. Further, the pattern film is sandwiched between both faces of a first surface plastic card and a second surface plastic card so that the film can be seen directly from outside. Under the described structure, the continuity state of the continuity lines 1-9 is confirmed by bringing a check pin into contact with a check terminal part from outside and further it can be confirmed that the periphery of the check terminal is in a non-continuity state. Consequently, it is impossible to set a prepaid card which is set in a non-continuity state by punching a hole, in the continuity state.

Title: Manufacture of semiconductor device
Inventor: SHIMADA TAKASHI
IPC: H01L27/08
Filed: 1988-11-30
Abstract: PURPOSE:To prevent the formation of a parasitic channel along the sidewall of a groove and to prevent the generation of leaking currents by forming the groove in a semiconductor substrate, doping impurities into the upper part of the side wall of said groove, and forming a channel stopping region. CONSTITUTION:An n<+> type channel stopping region 13 is formed on the sidewall of a deep groove 3 on the side of a p-type well 2. Even if fixed positive charge is present at the interface of SiO2/Si in the groove 3, the formation of a parasitic n-type channel is prevented at the part of said channel stopping region 13. Therefore, even if the parasitic-type channel is supposed to the formed along the sidewall at a part other than the channel stopping region 13 of the deep groove 3, the channel is discontinued at the part of the channel stopping region 13. Thus, the generation of leaking currents between a source region 9 and a drain region 10 and the generation of leaking currents between the source and drain regions 9 and 10 and an n-type Si substrate 1 through said parasitic n-type channel can be prevented. In this way, defects in CMOSLSI due to the leaking currents can be prevented.
