Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To store a wavelength for communication and a wavelength for broadcasting within a light amplifying zone of an EDFA (L-beam dope. fiber amplifier). SOLUTION: Light wavelength-multiplied with signal lights of wavelengths λ1-λ5 from a central station enters into an input waveguide 22-1 of an array waveguide grating(AWG) 10. The AWG 10 distributes components of the wavelengths λ1-λ5 of the lights to respective output waveguides 24-1-24-5. The signal light of the wavelength λ5 for broadcasting output from the optical waveguide 24-5 enters into a photo-branch-demultiplexer 28 via an optical waveguide 26 to be divided eqauly into four lights. The respective four-divided lights are propagated throught optical waveguides 36-42 to enter into input waveguides 22-2-22-5. The AWG 10 distributes the light of the wavelength λ5 from the input waveguides 22-2-22-5 to the output waveguides 24-1-24-4 respectively.

Inventor: KAWAI TAMOTSU
IPC: A23L3/358
Filed: 1989-07-28
Abstract: PURPOSE:To keep food fresh for a long period of time and prevent adverse effect on food by using a material made of a flexible base material on which an inorganic substance is applied. CONSTITUTION:This freshness keeping material is obtained by applying an inorganic substance on a flexible base material. The main ingredient of the inorganic substance is diatomaceous earth having respiratory function when applied to a container and adsorbs moisture coming out of food and prevents sweating in the container. The substance also has a pumping effect similar to that of the base material and therefore is capable of maintaining the temperature and humidity in the container constant. The baked powder content in the diatomaceous earth is 5-95% by weight. If the content is below 5%, property of preventing sweating on the container becomes weaker, while if more than 95%, mechanical strength becomes weak, although the property of preventing sweating is improved.

Title: Semiconductor light receiving element
Inventor: MURAMOTO YOSHIFUMI
IPC: H01L31/10
Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor light receiving element in which the maximum value of a current density near its incident end is lowered and which can make its output high, by a method wherein a second semiconductor layer and a third semiconductor layer as light guide layers are formed in such a way that their thicknesses are different from each other. SOLUTION: The thickness of an upper-part light guide layer 12 and that of a lower-part light guide layer 13 are different from each other, and the center of a light absorption layer 11 and the center of a core layer do not agree so as to be deviated. As a result, when light is incident on the center of the core layer so as to make its coupling efficiency maximum, the center of the distribution of excited waveguide light is deviated from the center of the light absorption layer 11. In a waveguide-type light receiving element, the confinement of light to the light absorption layer 11 is weakened due to its asymmetric structure, the concentration of the generation of carriers near its incident end is relaxed, and the generation of the carriers is dispersed to the longitudinal direction of a waveguide. As a result, the lack of uniformity of the distribution of a current density inside the p-n junction face of a photocurrent due to the generation of the carriers is relaxed, the maximum value of the current density near the incident end which limits the output of the light receiving element is lowered, and the output of the light receiving element can be increased.

Inventor: GONDA SHOSUKE
IPC: B42D15/10
Filed: 1994-07-29
Abstract: PURPOSE:To prevent a printed matter from being forged by copying and make printing without taking a dot gain into consideration. CONSTITUTION:Characters 'copy' made of dots with the setting of a screen ruling of 150 and a screen density of 20% are printed on a surface of a printed matter 1 as a warning indication pattern 2. Dots of the same size as the dots of the warning indication pattern 2 are densely and uniformly arranged around the warning indication pattern 2 so as not to overlap on the warning indication pattern 2. A bad<ground pattern 3 with the setting of a screen ruling of 65 and a screen density of 20% is printed. Since dots of the same size are differently distributed with different screen rulings, printing can be made without taking a dot gain into consideration. In addition, both the patterns 2, 3 cannot be discriminated by naked eyes. On the other hand, when the printed matter 1 is copied within a predetermined density range by a copying machine, the warning indication pattern 2 is revealed in the form of open characters and visually identified, and the copied matter can be found at a glance.
