A semiconductor device comprises a semiconductor substrate having an through hole, a first insulation resin layer formed on an inner surface of the through hole, a second insulation resin layer formed on at least one of front and rear surfaces of the semiconductor substrate, and a first conductor layer formed in the through hole to connect at least both front and rear surfaces of the semiconductor substrate and insulated from the inner surface of the through hole with the first insulation resin layer. A second conductor layer (wiring pattern) which is electrically connected to the first conductor layer in the through hole is further provided on the second insulation resin layer. The conductor layer formed in the through hole and constituting a connecting plug has a high insulation reliability. Therefore, a semiconductor device suitable for a multi-chip package and the like can be obtained. Further, since the forming ability of the conductor layer connecting the front and rear surfaces and the insulation layer is high, the manufacturing cost can be reduced.

A stacked electronic part comprises a first electronic part which is adhered onto a circuit board via a first adhesive layer and a second electronic part which is adhered onto the first electronic part via a second adhesive layer. An insulating resin having a filling viscosity of 1 Pa·s or more and less than 1000 Pa·s or a photo-setting insulating resin is filled in the spaces below first bonding wires which are connected to the first electronic part. Thus, the occurrence of bubbles resulting from the resin non-filled portions below the wires can be prevented. Besides, the first electronic part and the second electronic part are adhered via an insulating resin layer having an adhering viscosity of 1 kPa·s or more and 100 kPa·s or less. Therefore, the occurrence of an insulation failure, a short circuit or the like resulting from a contact between the bonding wires of the lower electronic part and the upper electronic part can be prevented.

A method for setting up a program profile in the control of the injection speed of injection molding machines where a model shape of an article to be molded is divided into fine elements; the filling up state of melt resin for each fine element is obtained as a time period by using numerical analyzing methods including the finite element method, the boundary element method, the calculus of finite differences method and the FAN method under a condition that the moving speed of the injection plunger is constant; a time period required for filling the model shape of the article as a whole with melt resin is divided into a plurality of material filling up time periods by an arbitrary number; a mean discharge speed Cv1 to Cvn of melt material at every divided period is calculated; and a moving speed of the injection plunger Pv1 to Pvn at every divided period is set up as a function of the mean discharge speed Cv2 to Cvn.
摘要:
A compressor unit in which the oil separated by a plurality of oil separators to a gas suction side pipe of the previous stage oil separator which contains gas whose oil concentration is higher than that of the gas from which oil has been separated, with the separated oil being returned to a compressor. The plurality of separators enables a simplification of the arrangement of the oil returning pipe, a prevention in a reduction in the discharge flow rate of the compressor, and reduction in space required for the separators.
摘要:
A refrigerator having a pressurizing device, a coldness generating device for generating coldness by expanding a portion of operating fluid which has been pressurized by the pressurizing device and a fluid passage through which the operating fluid is, via a device to be cooled, again circulated to the pressurizing device after the residual portion of the operating fluid has been cooled by the coldness generating device. A regenerator type heat exchanger is disposed in the fluid passage through which the operating fluid passes, and a switch device switches the flow of the operating fluid in the fluid passage to the reverse direction at a predetermined time period.
