Title: Low loss fiber optic coupler and manufacture thereof
Inventor: JIYOOJI EDOWAADO BAAKII
IPC: C03B37/025
Filed: 1986-08-14
Abstract: A low loss fiber optic coupler is fabricated by forming a coupler preform having a plurality of spaced glass cores extending longitudinally through a matrix of glass having a refractive index lower than that of the cores. The coupler preform is formed by inserting a plurality of coated optical fiber preform rods (26,27,28) into an aperture (20) extending axially through an elongated boule (21) of relatively etchable matrix glass. The cladding portion (35) of the rods, which is relatively etch-resistant, is coated with a layer of etchable glass (36). The coupler preform is heated and stretched to form a glass rod (43) which is then severed into a plurality of units (45; 49). Heat is applied to the central region (66) of each unit, and the central region is elongated and tapered inwardly. When an end of the unit is immersed in acid, the matrix glass dissolves, thereby leaving the unit cores and surrounding etch-resistant cladding glass protruding from the newly formed endface of the unit.

Title: Radiant-wave sensor
Inventor: KOTADO SETSUO
IPC: H01L27/14
Filed: 1990-07-19
Abstract: PURPOSE:To detect the optical power accurately independent of wavelength especially in a short wavelength region with high sensitivity by a method wherein a bismuth film is used as a radiant-wave absorber thin film at a radiant-wave sensor. CONSTITUTION:The absorption characteristic in an ultraviolet region of a bismuth film is nearly definite at a wavelength of 5mum or higher and displays an absorption factor of nearly 100%. Consequently, when the bismuth film is used as a radiant-wave absorber thin film at a junction point to be used as a hot contact of a thin-film thermocouple, it is possible to constitute a thermocouple-type radiant-wave sensor which is free form wavelength dependence and whose accuracy is high. An ultraviolet-absorbing filter 8 which has been installed so as to cover a first radiant-wave absorber thin film or a second radiant-wave absorber thin film 7A, 7B is installed on a second substrate 9. Thermocouples whose characteristics coincide extremely are arranged so as to be close to each other, and the radiant-wave absorber thin film 7A on one side is covered with the ultraviolet-absorbing filter 8. As a result, it is possible to obtain a definite detection sensitivity which is not influenced by an ambient temperature. Consequently, the sensor generates an electromotive force only when a flame as a source fire for a boiler exists; it is not influenced by the ambient temperature. As a result, it is possible to surely detect whether the source fire is burning or not and to prevent a gas explosion accident.

Title: Semiconductor device
Inventor: SAKURAI YOICHI
IPC: H01L21/60
Filed: 1990-07-19
Abstract: PURPOSE:To prevent deterioration due to changes with time by providing a semiconductor substrate with electrodes of the same potential and signal as those of respective electrodes at points opposed to the extraction zones of wires and rod-shaped or thin film conductors. CONSTITUTION:When a semiconductor substrate is P-type, it is always at the lowest potential: application of high potential onto an input/output electrode l forces electric field between a lead 5 and the semiconductor substrate. In this case, the distance between the lead 5 and the semiconductor substrate is determined by the height of a bump 2: ten and several microns. In general, resin is unstabler than the insulating film on the semiconductor: in the case where resin is impregnated with moisture, conductive particles in the resin move by electric field so that current flows if the insulating film is slightly conductive to deteriorate leads or semiconductor for a long term. This comes true to an N-type semiconductor substrate. Therefore, providing an electrode 3 of the same potential as that of an electrode 1 opposite a lead 5 allows application of no electric field between the lead 5 and the semiconductor substrate to prevent deterioration of the lead 5 or the semiconductor.

Title: Current control device for air conditioner
Inventor: MARUYAMA HIROSHI
IPC: F25B1/00
Filed: 1989-07-26
Abstract: PURPOSE:To expand and operating range by a method wherein a temperature at a fixing part of a semiconductor element to be used in a capacity control device is detected and a current limiting value is made variable in reference to this detected temperature. CONSTITUTION:As a three-phase AC power supply 6 is supplied, it is converted into a DC current through a rectifier element 7, the current is further smoothed by a smoothing capacitor 8 and supplied to a switching element 9. At this time, a control device 12 may switch over a switching element 9 to drive a compressor 1 at any frequency. As the rectifier element 7 or the switching element 9 is operated, the element itself may generate heat and its temperature is increased. As the compressor 1 is operated, a refrigerant compression within a freezing cycle is carried out to cause a heat generating operation to be performed and a surrounding air temperature is increased. As a result, a temperature of a heat radiation plate 2 is increased. However, this temperature is detected by a temperature sensor 10 and if the temperature is low, the current limiting value is set to a high value and in turn in case that the temperature is low, the current limiting value is set to a low value and it is made variable in response to the temperature. With such an arrangement, it is possible to expand an operating range in respect to the range of the current limiting value.

Title: Pattern defect selecting system
Inventor: FUJIWARA KATSUMI
IPC: G01N21/956
Filed: 1983-10-13
Abstract: PURPOSE:To process a black point, which is substantially harmless, as a harless defect, by adding an address, which detects the presence or absence of a close pattern in an external neighboring region of a risky region outside an outline. CONSTITUTION:A detecting address 115, which detects the presence of a close pattern, is added. Signals P1-Pn, which are obtained by the detecting address 115, are added to an AND 128. When all the signals P1-Pn are a 1, i.e., when the close pattern is present, a detected signal is outputted from the AND 128, with respect to a black point in a risky region outside an outline. Meanwhile, when a zero is sent to any of the signals P1-Pn, AND logic is not obtained by the AND 128. Therefore the logic does not have the close pattern. The sending of a defective signal is suppressed. Thus the black point, wherein the close pattern is not present, i.e., the black point, which is substantially harmless, can be processed as a harmless defect.
