Title: Dielectric radio wave absorber
Inventor: TANI MASATO
IPC: H05K9/00
Filed: 1999-04-12
Abstract: PROBLEM TO BE SOLVED: To absorb radio wave over a wide band from sub-millimetric wave band to millimetric wave band by specifying the thickness of a dielectric layer and return loss. SOLUTION: The radio wave absorber has a conductive layer and a dielectric layer wherein the thickness of the dielectric layer is 5 mm or less and the permittivity ε' and dielectric loss ε" of the dielectric layer are designed such that the return loss Γwill be 6 dB or above at frequencies 18 GHz, 50 GHz, 75 GHz and 100 GHz. Although a thinner absorber having a larger return loss Γis excellent, but when combinations of the permittivity ε' and dielectric loss ε' are calculated and analyzed over a wider range of frequency for practically required specifications of the return loss Γ of 6 dB or above, and the thickness of 5 mm or less, required specifications are satisfied in the range of 18-100 GHz regardless of the frequency.  Such a radio wave absorber is so-called wind band type and has radio wave absorption performance of 6 dB or above in the range of 18-100 GHz and degradation of characteristics due to fluctuation of thickness is negligible.

Title: Optical fiber core
Inventor: KITAYAMA YOSHINOBU
IPC: G02B6/02
Filed: 1983-06-10
Abstract: PURPOSE:To prevent increase of transmission loss at low temps. by specifying friction coefft. between the outside surface of a crude fiber and the inner surface of a tubular coat.

Title: Semiconducting roller
Inventor: NOJIMA KAZUO
IPC: G03G15/02
Filed: 1991-04-10
Abstract: PURPOSE:To provide a semiconducting roller having a resistance layer superior in noncohesive quality against toner, and free from the possibility of contaminating a photo-sensitive body. CONSTITUTION:A conductive elastic body layer 11 and a resistance layer 12 are laminated in order on a conductive base material 10. In addition, the resistance layer 12 is formed with tetrafluoro-ethylene-propylene rubber, or a mixture of epichlorohydrin rubber and fluorine polymer. The resistance layer 12 so formed has high noncohesive quality against toner, and toner filming hardly takes place thereon. Furthermore, the resistance layer 12 does not need the use of an interfacial active agent, a plasticizer or the like for adjusting rubber hardness or the like, and thus does not contaminate a photo-sensitive body. Also, the layer 12 has enough semiconducting quality without blending any resistance material such as carbon black. Roller characteristics, therefore, can be fully exhibited, even when the layer 12 is used for a charged roller.

Abstract: PURPOSE:To obtain the detector which can pass the infrared ray without fail, by epitaxially growing an N<+> type InSb layer on a P type InSb substrate in a liquid phase, abrading the substrate from the bottom surface in order to make the substrate thin, thereafter selectively forming an N type region reaching the epitaxial layer. CONSTITUTION:An N<+> type InSb layer 22 is epitaxially grown in a liquid phase on a P type InSb substrate 21. The bottom surface of the substrate 21 is mechanically abraded or etched, thereby the thickness of the substrate 21 is reduced to the thickness of serveral mum and the state of a mirror surface is obtained. Then, a protective film 23 having a specified pattern is formed on the mirror surface of the reduced substrate 21. A plurality of N type or N<+> type regions 24 reaching the inside of the substrate 21 are formed by the diffusion, the ion implantation, and the laser irradiation by using the windows provided in the layer 23. Then, the film 23 is removed, and the portion other than the coupling portion where other charge coupled device is directly coupled with the region 24 is covered by an insulating film 25 in order to prevent the generation of leakage currents. In this method, the characteristics of the detectors to be coupled with the charge couped device can be improved.
