IPC: G02B27/28
Filed: 1996-06-12
Abstract: PROBLEM TO BE SOLVED: To easily execute positioning work for a port by arranging a reflection board so that a forward light beam from a 1st port is reflected to an optical non-reciprocal part and a light beam reflected from a 2nd part in a reversed direction is not interrupted. SOLUTION: A transparent body 13 provided with a reflection board 15 is obliquely arranged between the optical non-reciprocal part 5 and an optical multiplexing part 10. The board 15 can reflect a forward beam A20 from the 1st port 20 to the non-reciprocal part 5 and is arranged on a position where the progress of a reverse light beam A2 generated from the 2nd port 2 is not interrupted. The beam A20 made incident upon the 1st port 20 collides with the board 15 to change its track to a horizontal direction and is made incident upon a double refraction plate crystal 7A. The beam A20 made incident upon the crystal 7A is separated into ordinary light y1 and extraordinary light x1 by double refraction. Crystal 7B multiplexes these separated light components to one light beam A2.

Filed: 1987-06-19
Abstract: PURPOSE:To obtain white frosted glass or semigloss Japanese paper like appearance having high heat resistance and mechanical strength and excellent light diffusivity, by compounding a predetermined amount of a glass fiber with a polycarbonate resin. CONSTITUTION:A glass fiber is pref. composed of E-glass containing no alkali and one called a milled fiber having a fiber diameter of 5-20mum and a fiber length of 5mm or less, especially, 100mum or less is pref. The compounding ratio of the glass fiber is 5-50pts.wt. per 100pts.wt. of a polycarbonate resin. When the glass fiber is below 5pts.wt. this inventive effect is not sufficiently developed and, when exceeds 50pts.wt., molding becomes difficult. The polycarbonate resin is generally obtained by reacting bisphenol A and phosgene or a carbonate precursor such as diphenyl carbonate. A part or the whole of bisphenol A may be substituted with dihydric phenol other than said bisphenol, for example, bis(4-hydroxyphenyl)sulfone or a nucleus lower alkyl substituted compound or nucleus halogen substituted compound thereof.

Inventor: FUJII HARUO
IPC: G03G15/24
Filed: 1981-09-25
Abstract: PURPOSE:To obtain vivid pictures of less photographic fog, by reducing the adhesive strength of a toner to a toner carrying medium in a recording position to reduce an applied voltage required for recording. CONSTITUTION:A carried toner is made into a uniform thin layer by a doctor blade 8 and reaches a recording position 10. When a voltage is applied to an electrode 9 provided in the breadthwise direction of a recording member 1, the toner which reaches the position 10 is stuck onto the recording member 1 to form a image. An electrode 11 is arranged a minute gap apart from the member 1, and an AC voltage is applied across the electrode 11 and a toner carrying member 6. A reciprocating force is given to the toner between the electrode 11 and the member 6 by the action of this AC electric field. The adhesive strength to the member 6 is reduced by this force so that the toner can be moved easily toward the member 1. As the result, a stable recording is possible with a low voltage applied to the electrode 9.
