Title: Wavelength converting switch
Inventor: KUROYANAGI TOMOJI
IPC: G02F2/02
Filed: 1990-05-19
Abstract: PURPOSE:To increase the degree of wavelength multiplexing while relaxing the request characteristics to wavelength converting elements by using the discrete type wavelength converting element and the continuous type wavelength converting element in combination. CONSTITUTION:The plural wavelengths multiplexed on the wavelength axis are branched in a branching section 1 and thereafter, the multiplexed light signals are separated on optical fiber transmission paths by a wavelength selecting section 2. The light signals selected by the wavelength selecting section 2 are sent to a wavelength conversion part 3. The light signals are subjected to the discrete wavelength conversion by longitudinal mode oscillation by the discrete type wavelength converting element of the wavelength conversion part 3 in this part. Further, the wavelengths are continuously converted between the mode wavelengths while the same longitudinal mode is maintained by the continuous type wavelength converting element cascade-connected to the discrete type wavelength converter 3 is thereafter coupled by a coupling part 4 which outputs the wavelength multiplex light signal after switching. The degree of the wavelength multiplexing is increased in this way while the request characteristics to the wavelength converting elements are relaxed.

IPC: B29C48/03
Filed: 1987-05-26
Abstract: PURPOSE:To shorten the change-over time of synthetic resin and at the same time reduce the usage of purging material by a method wherein specified purging material, which is compatible with the second synthetic resin, is fed to an extruder and, after the purging of the first synthetic resin, the second synthetic resin is fed in order to displace the purging material. CONSTITUTION:Purging material, which is formed by blending 1-20 wt.% of fine moisture absorbent particles with synthetic resin compatible with the second synthetic resin and having a melt index less than or equal to 40 dg/min, is fed to an extruder in order to purge the first synthetic resin. After the purging of the first synthetic resin, the second synthetic resin is fed to the extruder in order to displace said purging material. The first synthetic resin is polyester and the second synthetic resin is polyolefin. As the fine moisture absorbent particle, moisture absorbent, which contains 0.05 wt.% or more and the particle diameter of which is 0.1-150 mum, preferably 1-25 mum, is used. The purging material fed to the extruder is foamed by turning the water content in the purging material into steam under heat so as to remarkably expand its volume in the interior of the extruder, resulting in serving to expel the first synthetic resin.

Title: Flux cored wire for welding
Inventor: OKAZAKI ISAO
IPC: B23K9/12
Filed: 1980-09-17
Abstract: PURPOSE:To improve the arc stability durig welding and the shelf-life of a wire by forming the sectional shape of a metallic sheath packed internally with flux roughly into a square shape, and coiling the same in such a way that the joint part in the longitudinal direction of the metallic sheath directs toward the inner side direction of the coil. CONSTITUTION:Flux 8 is packed in a metallic sheath 7 of roughly a square shape in section, whereby a wire is formed. When the wire is coiled with the joint in its longitudinal direction directed to the inner side, contracting pressure is exerted upon the inner side of curvature, and the joint part of the metallic sheath 7 always receives force in the direction of closing the mouth and is shut off from the atmosphere, thereby preventing the packed flux from deteriorating. At the time when the wire is coiled to a winding core 9 and is supplied with electricity by a welded torch 11, the rotation of the wire at the tip 10 of the torch 11 does not occur and therefore electricity can be conducted stably, the arc is stabilized, and the occurrence of wear in the tip 10 is obviated.

Patent JP-S618595-A (JP)
Title: Heat pipe
Inventor: FURUKAWA YUUICHI
IPC: F28F19/06
Filed: 1984-06-22
Abstract: PURPOSE:To prevent a heat pipe from deteriorating even if the amount of generated hydrogen is high thereby improving the durability and life, by forming a titanium covering layer on at least part or all of the inner surface of a condensing section of a container. CONSTITUTION:At least part or all of the inner surface of a condensing section 1 of a container is formed with a titanium covering layer 3. As the hydrogen partial pressure balances with the pressure of water as operating fluid in the heat pipe, the hydrogen partial pressure particularly at high temperatures is very high relative to that in the atmosphere, and a hydrogen concentration gradient is formed between the outside and inside of the heat pipe. On the other hand, as titanium has such properties that the hydrogen solubility is high but the hydrogen absorbed therein can be released easily, the hydrogen gas in the heat pipe can be quickly absorbed into the titanium coating layer due to the concentration gradient and can be transferred into the iron. The transferred hydrogen migrates in the iron having a high hydrogen diffusion coefficient to part where the concentration gradient is low and then is released into the atmosphere. As a result, hydrogen gas can be prevented from accumulating in the condensing section, and the safe operation can be done perpetually.

Title: Optical scanning device
Inventor: TANAKA YOSHIO
IPC: G02B26/10
Filed: 1991-05-02
Abstract: PURPOSE:To improve the resolving power by properly setting the polarization state of luminous flux incident on the deflection reflecting surface of a polarizer and a scanning lens and the shape of a spot on a scanned surface. CONSTITUTION:The laser luminous flux emitted by a light source part 1 is sectioned in an elliptic shape which is long in a main scanning direction so that luminous flux in a spot shape which is long in a subscanning direction is made incident on the scanned surface 9; and S-polarized light is obtained on the deflection reflecting surface 4a. Then the polarization state of the luminous flux incident on the polarization reflecting surface 4a and scanning lens 7 is converted through a lambda/2 plate 14 from S-polarized light to P-polarized light. At this time, respective elements are set for the scanning lens 7 so that alpha<1.2thetaB, where alpha is a surface alpha of incidence on each lens surface and thetaB is the Brewster angle. For the purpose, variation in the reflection factor of each lens surface is reduced by obtaining the P-polarized light as the luminous flux incident on the deflection reflecting surface 4a and scanning lens 7 by using the lambda/2 plate 14 and an irregularity in illuminance on the scanned surface 9 is reduced over the whole scanning angle range.
