Title: Sterilizing lamp
Inventor: MATSUNO HIROMITSU
IPC: H01J61/72
Filed: 1987-11-24
Abstract: PURPOSE:To prolong the usable life of a sterilizing lamp and to prevent decrease in output of UV light at low temperatures by using cold cathode to light the sterilizing lamp in the normal glow discharge range and by utilizing a double tube structure enclosing a mixture of dilute gas and mercury. CONSTITUTION:The lamp consists of a hard glass tube 1 with good transmittance at about 254nm and a hollow shaped cold cathode 2, 2 made of an alloy of iron-nickel. As the gas for discharge, argon and mercury are enclosed. When the lamp is lighted in the normal glow discharge range of 20mA, a resonance line of mercuric atom is irradiated strongly to provide adequate sterilizing effect and long usable life of more than 20,000hr. In addition, a quartz glass tube attached with cold cathode 2, 2 on both ends is prepared and a mixture of argon and mercury as the gas for discharge is enclosed in it. This sterilizing lamp is placed in the outer tube 4 made of quartz glass having the same properties as the hard glass tube 1 and the outer tube 4 is evacuated. In addition to the resonance line of mercury of 254nm, UV light of 185nm is irradiated outward. UV light at 185nm changes O2 in the air into ozon. Since ozon has potent deodorizing effect, both sterilizing and deodorizing efficiency can be obtained.

Title: Surface-emitting laser
Inventor: MAACHIN DEEBITSUDO DOOSON
IPC: H01S5/34
Filed: 1995-11-13
Abstract: PURPOSE: To improve continuous wavelength single lateral mode operation output by causing the MQW active region to have many quantum wells at the center area than the peripheral area. CONSTITUTION: An MQW active region 16 is epitaxially deposited as a plurality of quantum well layers on a lower spacer region 14. The active region 16 is formed by the etching in such radial layer structure that the total number of quantum wells at the center area 16a is gradually reduced in number to single well at the periphery area 16b of the isolated region 16. Optical gain of the quantum well saturates as the injected current increases due to the step like mode in the density of the electronic states. A single quantum well becomes transparent in the lowest intensity of injected current. The available total gain becomes higher with increase in the number of quantum wells. The available total gain radially changes by etching the structure radially from MQW at the mode center to SQW at the peripheral edge, and it is possible to maintain the basic lateral mode.

Abstract: PURPOSE:To prevent the penetration of dust or rainwater in a case from an opening part by bringing the opening being a hose delivery port formed to the case and the stopper provided on the way of a hose to a close contact state. CONSTITUTION:A hose real 10 is provided in a case 1 and the hose 12 wound around the hose reel is led out of the case 1 through the opening formed to the case 1. For example, conical recessed parts 18, 19 are formed to the opening 17 formed to the case 1 while the stopper 20 provided on the way of the hose 12 is formed into the spherical shape fitted to the conical recessed part 18. Since the spherical stopper 20 is caught in the conical recessed part 18 in such a state that the stopper 20 is in contact with the opening 17, the spherical stopper and the conical recessed part become linear contact and, even when slight variation is generated in the size of a sphere and the taper angle of a conical shape, the contact position in the conical recessed part is naturally adjusted and, therefore, the stopper and the opening are certainly brought to a close contact state and the penetration of dust or rainwater in the case can be prevented.

Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To reduce capacity loss when a wide band code division multiple access (CDMA) (W-CDMA) system which uses several carriers overlaps an IS-95 carrier. SOLUTION: First of all, a carrier use/interference level for each carrier is decided. On the basis of the decided level, a demultiplexer 114 non-uniformly distributes a carrier allotment. This distribution operates so that it avoids a carrier the use rate/interference of which is high and selects a carrier. For example, in the case of a three carrier system in which a carrier f1 is used by an IS-95 user, while f2 and f3 do not have the IS-95 user, diffusion is non- uniformly distributed across three frequencies like f1 , f2 , f3 , f2 , f3 , f1 , f2 , f3 , f2 , f3 ,....
