IPC: G02B6/26
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a stable semiconductor laser module whose connection efficiency between a semiconductor laser and a core enlarging fiber is high by specifying the enlargement rate of a core and the change rate of a mode field diameter. SOLUTION: The semiconductor laser module 10 is provided with a semiconductor laser 11, a first lens 12, a second lens 13, a core enlargement fiber 14 and an airtight case 20. In the core enlargement fiber, the enlargement rate of the core is set to be more than 1.3 and the absolute value of the change rate of the mode field diameter to be smaller than 6.0×10<-4> μm<-1> . Thus, the dispersion of connection efficiency in the assembled module becomes small and the module of high connection efficiency can stably be manufactured. The change rate of the mode field diameter in the core enlargement fiber 14 can be controlled by various means on the flow rate adjustment of fuel gas and the control of the size and temperature of flame at the time of heating a single mode fiber by a burner and enlarging the core.

Title: Power amplifier
Inventor: SHIRASE TATSUO
IPC: H03F1/02
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To provide a power amplifier, reducing unwanted radiation from a switching power source. SOLUTION: When output signal levels of output terminals 19 and 20 are small, the output voltage of a switching power source 10 is made small by the output signal of an adding circuit 8. As a diode 18 is turned on, when the output voltage of the power source 10 becomes lower than a prescribed voltage, the power source voltage Vx of first and second SEPP amplifiers 4 and 5 becomes V1. Then, by the power source voltage Vx becoming V1, transistors 12 and 13 are turned off, to turn off the switching operation of the power source 10. Thereby the switching operation of the switching power source is stopped, while an input signal is at a small level so that unwanted radiation is reduced.

IPC: C07C233/18
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To produce a fatty acid alkanolamide having excellent purity and color on an industrial scale in high efficiency and shortened reaction time. SOLUTION: A fatty acid alkanolamide is produced by reacting a fatty acid with an alkanolamine by adding the alkanolamine to the fatty acid in two steps.

Title: Pattern forming material
Inventor: ENDO MASATAKA
IPC: G03F7/004
Filed: 1988-10-06
Abstract: PURPOSE:To prevent the deterioration in the resolution and contrast of resist patterns generated by light absorption on a resist surface by constituting the pattern forming material of a specific compd. and alkali soluble resin. CONSTITUTION:This pattern forming material is constituted of the compd. contg. a noncyclic material which does not contain a benzene ring and is expressed by formula I and the resin. Since the compd. of the formula does not contain the benzene ring, photofading progresses largely and the mol. wt. is increased by increasing the number of the constituting carbon atoms to about >=7 pieces, by which the solubility of the resin in an alkaline developing soln. is retarded and the film decrease of the resist in the unexposed part is prevented. The patterns are formed with high contrast, high resolution and high accuracy in this way at the time of exposing and developing by far UV rays and excimer laser light in particular. The formation of the finer semiconductor elements is possible and the yield is improved.
