Patent JP-H05313094-A (JP)
Title: Optical isolator
Inventor: TOJO MASAAKI
IPC: G02B27/28
Filed: 1992-05-13
Abstract: PURPOSE:To reduce the number of parts, and simplify an optical axis adjustment by constituting a reflection type optical isolator only of a single lens. CONSTITUTION:A birefringent crystal 4 is arranged on one side of a single lens 6, and a 1/2 wave length plate 5 is arranged between this lens 6 and the birefrigent crystal 4 so as to cover an area half of the lens 6. A reflecting mirror 8 is arranged on the other side of the lens 6, and a platelike magnetooptical crystal 7 whose length is determined so that planes of polarization of incident light 11 and outgoing light 18 become different from each other by pi/8+Npi/4 (N=0, 1,...), is arranged between the lens 6 and the reflecting mirror 8. A light beam 1 incident so as to pass through the 1/2 wave length plate 5 is reflected by the reflecting mirror 8, and passes through into the 1/2 wave length plate 5, and light 18 is outputted. In this way, since the light beam is used by passing through the respective single birefringent crystal 4, lens 6 and magnetooptical crystal 7 twice, the number of parts can be reduced. Since optical fibers 1 and 2 are formed in an array structure, optical coupling can be made simply by adjusting the optical axes of an optical fiber array 3 and the lens 6.

Title: Carbon ink for forming thermosetting pattern and method for pattern formation
Inventor: SHIMADA MIKIYA
IPC: C09D11/10
Filed: 1990-05-10
Abstract: PURPOSE:To form a fine conductive body or a fine line pattern by an inexpensive and simple printing method by cutting a metallic org. compd. paste printed on a thermoset carbon ink on the ink and removing the ink by burning at high temp. CONSTITUTION:After printing is performed on an alumina glaze board 1 by using a carbon ink 8 for forming a thermoset pattern, the thermosetting carbon ink 8 is dried and cured by heating. Then, for example, an org. gold compd. paste 9 is printed on the thermoset carbon ink 8 and cut thereon with a cutter as illustrated with a cut line 10. The cut piece is dried and burned in air to form a thin gold film layer 2 and to burn and remove the carbon ink 8 located below. As the thin gold film is left as a burr at the part where the ink 8 has been printed, this is removed with a gum roller to form an electrode pattern for a heat generating part of a thermal head with a sharp apex shape of the pattern.

Title: Auxiliary signal transmission system
Inventor: SUYAMA SHIGEKI
IPC: H04L25/49
Filed: 1988-05-17
Abstract: PURPOSE:To send an auxiliary signal with a small circuit scale by applying pulse frequency modulation to an auxiliary signal input waveform and using the frequency modulation pulse so as to give 1B2B coding rule violation to a 1B2B code of a master signal. CONSTITUTION:An input waveform of an auxiliary signal inputted to an input terminal 6 is subjected to pulse frequency modulation by a modulation circuit 10 of the pulse frequency modulation system and a modulation pulse (a) is outputted. A retiming circuit 11 applies retiming to the modulation pulse (a) by a clock signal of a master signal and synchronizes it with the master signal and the result is fed to a CRV control input 13 of a coding circuit 1. In the presence of a modulation pulse (b), the coding circuit 1 applies CRV to the coding rule of the master signal. On the other hand, CRV is detected as soon as the master signal is decoded by a decoding circuit 2 at the reception side to obtain a waveform of a CRV detection signal (d) at a CRV detection output 14 and the signal (d) is used to demodulate the pulse frequency modulation at the demodulation circuit 12 thereby recovering the auxiliary signal waveform.

Title: Thermal decomposition of saccharides
Inventor: UEMATSU TOSHIKATSU
IPC: C01B31/02
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To sufficiently suppress caramellike foaming and prevent overflow in thermal carbonization of saccharides and improve the operability, workability and productivity in thermal decomposition of the saccharides, by adding and mixing a specified amount of an oil and fat with the saccharides and thermally decomposing and dehydrating the saccharides. SOLUTION: An oil and fat, having <=200 deg.C melting point and selected from among Tempura oil, salad oil and linseed oil in an amount of 0.1-3.0 wt.% based on saccharides such as sucrose, maltose and lactose is added thereto and mixed for >=10 min to provide a mixture, which is then laminated so as to afford <=10 cm thickness, heated up to about 200 deg.C taking >=30 min, kept for >=2 hr and dehydrated and decomposed. At this time, matters to be attended are as follows: Since properties of a carbide may remarkably be modified with various kinds of trace components contained in black sugar, molasses, raw sugar, etc., the raw material should carefully be selected. When the amounts of saccharides and oil and fat to be mixed are small, both are mixed with a stirrer. When the amounts are increased, a kneading apparatus having a large torque such as a kneader is used.

Title: Optical fiber cord with plug and its manufacture
Inventor: IKEDA HIROYOSHI
IPC: G02B6/36
Filed: 1982-07-12
Abstract: PURPOSE:To prevent a decrease in optical coupling efficiency by forming a recessed part in an exposed surface of an optical fiber to a larger diameter than a small diameter hole formed in a plug, and fusing and charging a tip part of the optical fiber in the recessed part and forming a large diameter part of the optical fiber. CONSTITUTION:The recessed part 11 having the larger diameter than the small hole 4 piercing the optical fiber 7 is formed in the end surface of the plug 1, and the end part of the fiber 7 is fused and charged closely in the recessed part 11 to form the large diameter part 12, whose exposed end part is abrasive finished.
