Filed: 1981-12-15
Abstract: PURPOSE:To simply produce a metal-embedded synthetic resin molded product  in a complicated shape, by a method wherein a thin metal sheet being excellent  in an extensibility is embedded in a synthetic resin layer to form a subject primary molded product, and the primary molded product is then secondarily molded into a shape being different in that of the primary molded product. CONSTITUTION:A thin metal sheet 2, being excellent in an extensibility, i.e., that which improves the extensibility by forming a number of slits 6 in a metal such as thin metal sheet, and is for use in a copper, zinc, etc., is embedded in synthetic resin 1 to form a metal-embedded synthetic resin primary molded product 3. The product 3 is continuously formed into a similar sectional shape by an extrusion molding wherein a cross head die 5 is employed. An arrow (a) indicates a feed direction of synthetic resin and an arrow (b) shows the feed direction of the thin metal sheet 2. The laminar or tubular metal-embedded synthetic resin primary molded product 3 is secondarily molded into a shape being different from that of the primary molded product 3 by a blow molding, a press molding and other molding methods to simply obtain a complicated secondary molded product 4. An illustrated example shows an eaves trough.

Title: Sigma-delta analog-to-digital converter proviped with filtration with controlled pole-zero place and equipment based thereon
Inventor: REOPORUDO AANESUTO PERON
IPC: H03M3/02
Filed: 1994-08-04
Abstract: PURPOSE: To suppress an ADC noise by subtracting a pulse intensity modulating signal or an amplitude modulating signal prepared by a sigma/delta analog/ digital converter ADC from an input analog signal, and processing an obtained error signal by a feedback loop including a resonator. CONSTITUTION: A sigma/delta analog/digital converter ADC 210 receives a band-limited analog input signal, and subtracts the analog replica of a pulse intensity modulating signal PDM or an amplitude modulating signal ADM prepared by the ADC 210 from the input signal. Then, an error signal is obtained, and the error signal is processed by a resonator 758 forming an analog filter. The resonator places a Z-face pole on a unit circle at a place displaced from a zero frequency in an open structure, places zero in the unit circle, and prepares a resonance signal. The ADC 210 processes the resonance signal, and a D/A converter 218 converts it into the replica, and supports the preparation of the error signal. As a result, the noise of the ADC 210 can be suppressed by using a feedback loop including the resonator 758.

Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To obtain a sensor which can restrain water from creeping into a protective cover by a method wherein protrusions which protrude toward the outside of the protective cover are formed in the edge part of a through hole at least on one layer of the protective cover. SOLUTION: An oxygen sensor 1 is provided with a protective cover 3 which covers a detection part 2. The protective cover 3 is provided with a cylindrical inner cover 4 and with a cylindrical outer cover 5. A gap 7 is formed between the inner cover 4 and the outer cover 5. Inner through holes 41 and outer through holes 51 are formed nearly in the whole regions in the circumferential wall of the inner cover 4 and in the circumferential wall of the outer cover 5 in such a way that they are dispersed alternately at prescribed intervals. In addition, first protrusions 53 and second protrusions 43 are formed respectively at the outer through holes 51 and the inner through holes 41. Then, the first protrusions 53 act as barriers to water which creeps into the outer cover 5, and the water is hard to creep into the outer cover 5 from the outer through holes 51. Consequently, it is possible to restrain the water from creeping into the gap 7 between the the inner cover 4 and the outer cover 5. Even when the water creeps into the gap 7, the second protrusions 43 act as barriers to the water which creeps into the inner cover 4, and the life of the detection part 2 can be made long.
