Title: Extremely low temperature refrigerator
Inventor: UNO TAKAHIKO
IPC: F25B9/00
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To obtain a stable refrigerating capacity not being affected by fluctuation of outdoor air temperature, without using an intermediate unit. SOLUTION: A sprinkler 17 sprinkling water on a heat exchanger 14 is fitted to a compressor unit 11. A nozzle 19 sprinkles water in a water tank 21 over radiating fins 23 of the heat exchanger 14 to cool them. Thereby the efficiency of heat exchange of the heat exchanger 14 in summer in a warm district is enhanced and a refrigerating capacity equal to the one of a usual extremely low temperature refrigerator equipped with an intermediate unit is obtained. In the case when an ambient temperature T is a prescribed temperature T1 or below, a control part 26 operates a fan 15 at a medium speed and closes a motor-operated valve 29 to stop sprinkling of water. When the temperature is higher than the prescribed temperature T1, it operates the fan 15 at a high speed to increase the quantity of sprinkled water in proportion to ambient temperature T.

Inventor: KONO SHINJI
IPC: H04M3/08
Filed: 1987-12-04
Abstract: PURPOSE:To instantly offer the fault information of a digital circuit by setting a fault area to a trunk state data in an interactive data with an exchange set to a digital trunk. CONSTITUTION:When a call is sent through a private line from a subscriber 1, a central processing unit 6 sends an acquisition check command data to a digital trunk 4 to request conversation.

IPC: G03C1/79
Filed: 1991-10-25
Abstract: PURPOSE:To prevent blocking with a cooling roll and staining by cooling without impairing the adhesion of a molten polyolefin resin and a paper base even if a coating speed is increased by blowing cold air to the surface on the cooling roll side of the film of this resin and blowing an ozone-contg. gas to the surface on the paper base side. CONSTITUTION:The surface for contact with the resin of the paper base 1 is previously subjected to an activation treatment by a corona treatment. The cold air kept at 15 to 30 deg.C is blown from a bar 5 of a slit type to the surface on the cooling roll 7 side of the molten polyolefin resin film 2 extruded from a T die 4 of an extruder, by which the film is cooled. Further, an ozone-contg. gas kept at 20 to 70 deg.C is blown from a bar 3 of a slit type to the side in contact with the paper base 1 of the molten polyolefin resin film 2 extruded from the T die 4 of the extruder. Such cooling is combined, by which the degradation in the adhesive power is obviated and the staining is prevented even if the resin temp. in the outlet of the T die 4 of the extruder is kept at 250 to 300 deg.C.

Title: Manufacture of thermosetting resin laminated sheet
Inventor: IIDA TAKAHISA
IPC: B32B5/00
Filed: 1987-12-07
Abstract: PURPOSE:To improve the drilling performance of a laminated sheet and consequently make it possible to increase the number of piled-up sheets at drilling by a method wherein glass cloth, which is embrittled so as to make both the longitudinal and lateral bending strengths of the laminated sheet not larger than specified values, is employed as base material. CONSTITUTION:Glass cloth, which is embrittled so as to make both the longitudinal and lateral bending strengths of a laminated sheet not larger than 50kg/mm<2>, is employed as base material. The positional accuracy of the small diameter drilled hole clearly correlates with the bending strength of the laminated sheet. The decrease of the amount of curve of the drilled hole is proportionate to that of the bending strength of the laminated sheet. However, the bending strength of the base material having not small than 50kg/mm<2> does not effect the decrease of the amount of curve of the drilled hole. Further, if the bending strength of the base material is not larger than 20kg/mm<2>, the breakage or the like of the base material may develop during coating process and forming under heat and pressure, resulting in being apt to reduce productivity. Furthermore, in order to lower the bending strength of the laminated sheet, embrittled glass cloth is necessary. As normal embrittle treatment, comparatively longer heat cleaning at high temperature such as 400 deg.C or higher, immersion in acid or alkaline solution or mechanical opening or the like of glass cloth is employed.
