Title: Optical communication system
Inventor: SAKURAI AKIRA
IPC: H01S5/00
Filed: 2001-02-26
Abstract: PROBLEM TO BE SOLVED: To provide an optical communication system having high reliability with respect to deterioration of a plane light-emission type semiconductor laser device. SOLUTION: In a lower semiconductor distribution Bragg reflector and an upper semiconductor distribution Bragg reflector, a low refraction index layer and a high refraction index layer, which constitute a structural layer of a long wavelength band plane light-emitting semiconductor laser device, are alternately and periodically laminated. Such a material layer that a refraction index takes a value between two layers is provided between the low refraction index layer and the high refraction index layer. This material layer varies a composition as having a slope from a composition of the high refraction index layer to a composition of the low refraction index layer, whereby the refraction index changes continuously or stepwise. Thus, the generation of a hetero barrier generated on an interface of two types of semiconductor layers which constitute the semiconductor Bragg reflector is prevented, thereby lowering electric resistance of the Bragg reflector. Such the material layer can be formed by controlling a gas flow rate when forming the layers.

Title: Oil-water separator
Inventor: FUNAKOSHI TOYOMATSU
IPC: B01D17/02
Filed: 2001-02-06
Abstract: PROBLEM TO BE SOLVED: To automatically separate a large quantity of oil and water by a simple and small device by utilizing a specific gravity difference between oil and water. SOLUTION: A hole is bored in the bottom of a container made of a metal, or the like, to constitute a separation container and the hole is used as a drain port. A flat float with a specific gravity of 0.95 made of a metal, wood, or the like, is placed in the separation container of oil and water and an oil outlet is provided to the upper part of a space slightly left with respect to the float to be fixed to the container body by a pipe. When an oil-water mixed liquid is put in the container, the float sediments if oil is much and floats if water is much and this up and down movement of the float is used as a valve. Oil and water are separated by utilizing this theory. Further, an electromagnet is attached and, since the float does not come into contact with the container, the float and conductivity at a time when water is present on the bottom of the container body are utilized to mount the electromagnet on the upper or lower part of the container body to enhance a function. In this case, the float makes no bones about the specific gravity of 0.95.

Title: Air conditioner for vehicle
Inventor: KAMATA TAKAYUKI
IPC: B60H1/32
Filed: 2001-03-23
Abstract: PROBLEM TO BE SOLVED: To make it happen that both the anti-cloudiness of a window glass and cooling capacity for a vehicle room are secured for an air conditioner for vehicles performing only cooling without having a heating means. SOLUTION: When a target blowout temperature TAO is higher than a prescribed temperature, it is determined that the window glass of a vehicle is under a condition that it is subjected to cloud. When this determination is made, a target evaporator temperature TEO is lowered and FACE/DEF mode is set. As a result, highly dehumidifying air is blown on the window glass, so that the anti-cloudiness of the window glass is secured and the cooling capacity for the vehicle room is also secured while a cool wind is not blown at the foot of an occupant. Thus, both the anti-cloudiness and cooling capacity are secured simultaneously.

Title: Extracted coffee storing container
Inventor: KIJIMA SHOGO
IPC: B65D81/24
Filed: 2001-03-26
Abstract: PROBLEM TO BE SOLVED: To prevent an extracted coffee from oxidization and deterioration by suppressing leaking of air from outside into a storing container 40. SOLUTION: A pour-in pipe 42b is suspended into a container main body 41 from the extracted coffee pour in port 42a of a lid 42, and an air vent 42c for communicating the inside and outside of the pipe 42b is formed at the upper part of the pipe 42b. The extracted coffee dripping down to the pour-in pipe 42a flows into the main body 41 through the pipe 42b and the liquid surface of the extracted coffee is raised to soak the lower end part of the pipe 42b in the extracted coffee. Thus, even when the port 42a is increased, the quantity of air entering the container from the outside of the container can be restricted by the air vent 42c. Thus, by reducing the size of the air vent 42c, the extracted coffee is prevented from being oxidized/deteriorated in contact with air in the outside of the container.
