Title: Fused optical fiber and method of manufacturing the same
Inventor: RORUFU ROSUBERUKU
IPC: G02B6/34
Filed: 1990-09-10
Abstract: PURPOSE: To inexpensively produce a short polarization selective fusion-spliced optical fiber coupler by supplying linearly polarized light to one of input fibers, detecting the light at the terminal parts of two output fibers, continuously fusion-splicing the fibers, pulling the coupler until coupling between two fibers is stabilized, and then switching a heat source to OFF. CONSTITUTION: The linearly polarized light of a specified wavelength is supplied to one of input fibers 2 and detected at the terminal parts of both output fibers 3. Afterwards, non-birefringent single mode fibers are welded at a welding point 5, a coupler 1 is axially pulled at the same time, and the fibers are sharpened to be biconical. Pulling processing is finished when the part of coupling between two channels stops fluctuating and the same quantity of light exists at both the channels and afterwards, the light and heat source is switched to OFF. A hardened welding area 6 for determining the optical characteristics of the coupler is formed from output cross sections (a)-(d) of input fibers according to desired characteristics. Thus, the welding area of the coupler is especially shortened.

Title: Insulated-gate type bipolar transistor and manufacturing method thereof
Inventor: MIYASE YOSHIYUKI
IPC: H01L29/10
Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To improve a negative voltage noise immunity by suppressing local breakdown of an end with respect to negative voltage noise in an insulated-gate type bipolar transistor. SOLUTION: In the insulated-gate type bipolar transistor, a buffer layer 10' for shortening a turn-off time and preventing latch-up is provided, so as not to expose at an end cut face. With such a structure, a breakdown voltage of a p-n junction between a semiconductor substrate 1 and the buffer layer 10' becomes lower than that of a p-n junction between the semiconductor substrate 1 and an n-type layer 2 at the end cut face. Since the breakdown of the entire p-n junction between the semiconductor substrate 1 and the buffer layer 10' causes negative voltage energy to be absorbed through its wide area, its negative voltage immunity can be improved, when compared with that of a prior art having the exposed buffer layer.

Abstract: PURPOSE:To prevent the unauthorized use of a prepaid card by detecting that a prepaid card is forcibly exchanged before the remaining charge data are written after the card is inserted and rewriting the data of an authorized card to the data which do not allow the use of equipment when the unauthorized card is inserted. CONSTITUTION:A controlling section 18 stores the identification code number in a RAM and enables the holder of an inserted prepaid card to use a TV receiver 11 when the section 18 discriminates that the card is valid. Then the section 18 counts the number-of-service corresponding to the watching time of the receiver 11 at a set rate and, when the remaining number-of-service becomes smaller than the number-of-service corresponding to the unit watching time, the section 18 discriminates whether or not the card is forcibly exchanged by the holder. When the section 18 discriminates that the card is forcibly exchanged, the section discharges the card from a card inserting port and instructs a power supply controlling section 19 to discontinue the power supply to the receiver 11 after storing the identification code number stored in the RAM in a nonvolatile memory as the identification code number of an unusable prepaid card.
