Title: Manufacture of semiconductor device
Inventor: YOSHIKAWA MITSURU
IPC: H01L23/522
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To shorten an etching time and reduce sunny-side-up defects(SSDs) in an etch back method using spin-on-glass(SOG). SOLUTION: After the formation of an SOG film 4 on a plasma SiO2 film 3, only the film 4 is etched back by a predetermined thickness using a plasma- etching gas in which methyl trifluoride (CHF3 ) is mixed with ethylene hexafluoride (C2 F6 ) at a relatively low ratio, under the condition that the etch rate of the film 4 is relatively high. The films 3 and 4 are thereafter simultaneously etched back using a plasma-etching gas, in which CHF3 is mixed with C2 F6 at a relatively high ratio under a condition that a substantial etch selectivity ratio between the films 3 and 4 is close to 1. By reducing the ratio of mixture of CHF3 , the formation of deposited polymers that causes SSDs is suppressed.

Title: Fluid resistance device
Inventor: ITANO TSUTOMU
IPC: F15D1/02
Filed: 1984-11-13
Abstract: PURPOSE:To increase the rate of viscous resistance accounting for all resistance values without entailing any damage to easiness of a manufacturing process, by making a circular hole longer in its circumferential length as compared with a circle of the same area, and increasing the viscous resistance. CONSTITUTION:A lot of stellate holes 4 are installed in a flat platelike member, and further a reinforcing flat plate member 2 is layered thereon after removing pass holes 3 for inflow or outflow in or from these stellate holes 4. Each of these stellate holes 4 is longer in its circumferential length than a circle of the said area. With this constitution, as the ratio of viscous resistance to secure the specified resistance value to inertial resistance, the side of the stellate one becomes large in the rate of the viscous resistance as compared with the circle one, so that high speed motion is made more possible than that of the circle one.

Title: Cooling device
Inventor: FUJIYOSHI KOJI
IPC: F28F27/00
Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To extend a cycle for cleaning and maintenance of a heat exchanger in an arrangement in which heat is absorbed from a high temperature space through a heat exchanger, radiated into a low temperature space and at the same time fluid of low temperature is passed in the low temperature space by a cooling fan. SOLUTION: A fluid partition plate 7 dividing an inner part of a main body 4 of a device is provided with a heat exchanger 16. A high temperature space 8 communicated with an inside part of a housing 4 and a low temperature space 9 communicated with an external area are heat exchanged to each other by the heat exchanger 16. A low temperature side fan 24 causes external air to pass to the low temperature space 9 so as to improve a cooling effect of the heat exchanger 16. A driver 27 informs a rotating state and a load of a low temperature side fan motor 25 to a control device 21. When the control device 21 judges that a rate of clogging at the heat exchanger 16 is increased in response to a sensing state of the driver 27, it rotates the low temperature side fan motor 25 in a reverse direction, thereby dusts adhered to the heat exchanger 16 is blown off and cleaned.

IPC: F03B1/02
Filed: 1994-09-07
Abstract: PURPOSE: To prevent a runner blade from being deformed and damaged due to fatigue by overhanging each tip end section of the runner blade from the outer circumferential periphery of each side plate, and thereby installing a circular ring shaped seal plate covering each runner tip end section onto the side plates. CONSTITUTION: In a gap section between a runner 1 and casing 4, each circular ring shaped seal plate 8 is installed onto side plates 1d on the sides of their outer circumferences by installation bolts 8a. At the installation section of an inner blade 1c with each side plate 1d with the outer diameter of each side plate made small, the runner blade 1c is welded with each side plate 1d at its thick section of the runner blade 1c, and the tip end section thin in thickness of the runner blade is overhanged out of the outer circumferential periphery of each side plate 1d. Even in the cross flow turbine, water leak can be prevented by making the gap section small between the casing 4 and each seal plate 8.  The installation of each circular ring shaped seal plate formed as mentioned above thereby enables the runner blade 1c to be prevented from being deformed and damaged due to fatigue without impairing leak prevention performance to the outside of the runner 1.

Title: Paper-sheet reversing apparatus
Inventor: HASHIMOTO KIYOSHI
IPC: B65H29/58
Filed: 1984-11-13
Abstract: PURPOSE:To permit the smooth reversing processing for a paper sheet by regulating the sending-out angle by allowing the paper sheet transported by a roller to contact with the under surface of a flexible guide member and allowing said paper sheet to intrude at a shallow angle for the guide member and eliminating the generation of jam on the paper sheet in reversing operation. CONSTITUTION:Though a paper sheet P introduced into the first transfer passage 2 from a gate 4 contacts with a flexible guide 60 formed in crossing, said guide 60 is pushed-up by the transportation force of the paper sheet and deformed to the position shown by the alternating dotted line. Said guide 60 contact-presses the upper surface of the paper sheet P transported by a driving roller 11 and a trailing roller 12 by flexibility, and the sending-out angle of the paper sheet P is regulated. The paper sheet P pressed by the flexible guide 60 is sent-out and intrudes into an intermediate tray 15, keeping a shallow angle, and the top edge of the paper sheet P which contacts with the intermediate tray 15 smoothly rises along the wall surface of the tray 15. Therefore, the sending-out angle for the paper sheet is regulated by the flexible guide 60, and the transfer in the intermediate tray 15 is smoothly carried-out, and the generation of jam can be prevented.

CONSTITUTION:A start signal 30 has two scan pulses 30a and 30b which are isolated only during an odd period. As for an output terminal 22, a refresh signal is impressed on a refresh control line 14. When refresh transistors 12-1, 12-3, 12-5,... are electrified, contents in a cell #3 are outputted to the output terminal 22. On the other hand, if a read command signal is impressed on a read control line 16 and read control transistors 12-2, 12-4, 12-6,... are electrified, contents in a cell #4 are outputted to the output terminal 22. Thus the needless installation of two scanning circuits dedicated to refresh and dedicated to signal reading is omitted.

The MAH polyethylene is added in the mixing of the master batch with the polyethylene, and a cross-linking agent is further added thereto to form a compound. The compound is extrusion molded on a conductor with inner and outer semiconductor layers, and cross-linked by heating. As a result, the reduction in resistance to lightning impulse intensity by the polarized inorganic filler can be prevented to dispense with the increase in thickness of the insulating layer.
