Semiconductor apparatus and method of producing the same

A semiconductor apparatus including: a semiconductor substrate having a through hole; an electrode pad provided on a first surface of the semiconductor substrate so as to cover the through hole; an external connection terminal provided on a second surface of the semiconductor substrate; a conductive wiring passing through the through hole and allowing conduction between the electrode pad and an external connection terminal; a first insulating film provided on the first surface of the semiconductor substrate; and a second insulating film provided on a second surface of the semiconductor substrate and on an inner surface of the through hole to insulate the semiconductor substrate from the conductive wiring; the conductive wiring being connected to the electrode pad via the connection opening formed in at least one of the first insulating film and the second insulating film that are formed in such a way that at least a part of the first insulating film and a part of the second insulating film overlap, in a direction vertical to the first surface of the semiconductor substrate, the bottom surface of the through hole, and the connection opening being formed so as to avoid a periphery of the bottom surface of the through hole. This provides a semiconductor apparatus with a highly-reliable through electrode and a method of producing the apparatus.

Enzyme Laiyang pear paste and preparation method and application thereof

The present invention discloses enzyme Laiyang pear paste and a preparation method and an application thereof. The disclosed Laiyang pear paste is prepared by low-temperature fermentation of 7-14 jin of Laiyang pears and 1 part of traditional Chinese medicine decoction, and low-temperature and negative-pressure distillation and concentration. The enzyme Laiyang pear paste is characterized in that, the 1 part of the traditional Chinese medicine decoction is prepared by boiling the following medicinal materials: 8-13 grams of each of liquorice, dried gingers, red dates, buckwheat, radix puerariae, haws, smoked plums, wrinkled gianthyssop herbs, fructus amomi, poria cocos, Chinese wolfberry fruits, chrysanthemums, and fructus momordicae, 4-8 grams of semen sterculiae lychnophorae, 2-5 grams of each of rhizoma imperatae and bulbus lilii, and 5-9 grams of radix platycodonis. The present invention also discloses the preparation method of the Laiyang pear paste. Compared with the prior art, the active plant enzymes of the pear paste has effects of moistening lungs and stopping cough, clearing and benefiting throats, reducing fire and promoting salivation, harmonizing stomach and reducing phlegm, beautifying features and nourishing skins, preventing and treating haze syndromes, relieving toxins, lowering blood lipids, blood pressure, and cholesterol, and more effectively preventing and curing cancers, liver and kidney diseases, etc.

Breaker for providing successive trip mechanism based on PTC current-limiting device

ActiveUS20060186090A1Prevent deteriorationPreventing deterioration of a PTC current-limiting deviceCircuit-breaking switches for excess currentsContact mechanismsCurrent limitingEngineering
Disclosed is a breaker for providing successive trip mechanism based on PTC current-limiting device, which includes a first switch having first fixed/movable contact points; a second switch having second fixed/movable contact and connected to the first switch in parallel; PTC current-limiting device connected to the first and second switches in parallel or series and allowing a change of current flow direction from the first switch to the second switch at a fault current; a movable arm to which the movable contact points are installed at an interval therebetween and opening/closing the switches by operating the movable contact points; a fixed arm including first and second fixed arm conductors for guiding current flow toward the first fixed contact point in a normal load current mode and guiding current flow toward the second fixed contact point via the PTC current-limiting device in a fault current mode; and a successive trip means for elastically biasing the second switch by operation of the movable arm in a closing direction when both switches are closed and successively tripping both switches using time taken for releasing the elastic bias of the second switch when the movable arm is operated in a tripping direction.

Analyzing and monitoring method for circulating mother liquor during production of 1,2-dichloroethane

The invention discloses an analyzing and monitoring method for a circulating mother liquor during production of 1,2-dichloroethane. The analyzing and monitoring method comprises the steps of firstly sampling and weighing the mother liquor; carrying out preliminary filtration; weighing the mass of filter residues; distilling the filtered mother liquor; pre-setting a condensing temperature of a distillation system at -10 DEG C-20 DEG C; starting a heating device of the distillation device when a temperature reach the set condensing temperature; raising a distillation temperature to 80 DEG C-120 DEG C gradually; stopping distillation when the temperature stops increasing and starts to decrease under a continuously heating state; cooling to a room temperature; weighing the mass of the distilled residues; sampling and injecting a distillate into a gas chromatograph; normalizing corrected area to obtain chromatographic analysis results of various low-boiling point components; and converting by substituting the masses of the filter residues and the distilled residues into a formula to obtain the content of the various low-boiling point components in the mother liquor. The method provided by the invention is simple to operate and accurate in analysis results, and has good repeatability. The method is helpful to take measures in advance so as to prevent deterioration of ethylene chlorination.
