Title: Production of phenol resin
Inventor: INAGAKI MASAYUKI
IPC: B01D11/04
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To produce a phenol resin freed from impurities and having a controlled molecular weight distribution at good efficiency within a short time by removing the catalyst and the neutralization salt remaining in the phenol resin by means of a perforated-plate cross-flow centrifuge to simultaneously perform water extraction and separation. SOLUTION: A precondensate of a phenol resin and water are fed into a perforated-plate cross-flow centrifuge. Referring to an example in which the specific gravity of the phenol resin at the treatment temperature is higher than that of water, the phenolic resin fed from a heavy liquid side inlet 1 to a centrifuge rotating about a rotary axis 8 is fed from a heavy liquid feed nozzle 3 and moved outwardly or upwardly by the centrifugal force. On the other hand, the water is fed from a light liquid side inlet 2, fed through a light liquid feed nozzle 5, and moved inwardly or downwardly. The heavy and light liquids are distributed and mixed at good efficiency by a perforated plate 4 provided inside and then separated from each other.  The solvent and the neutralization salt remaining in the phenolic resin are extracted with the water, and the extract is pumped out from a light liquid side outlet 6, while the treated phenol resin is pumped out from a heavy liquid side outlet 7.

Inventor: SCHOENFELDER DIETBERT DIPL ING
IPC: F02D41/34
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To provide a control method for reducing the cost, and particularly a computation time while keeping the accuracy, by setting an angle corrected from the angle and hysteresis, and setting a number of increment on the basis of the corrected angle. SOLUTION: A hysteresis value H is added to a value of an angle for a control signal, to determine the corrected angle A* (S310). A number of increment INKA* is calculated from the corrected angle A*. Further the angle A* is divided by an increment width WINK. An integer part of the result is used as INKA* (S320). Then the remained angle RWA* is calculated (S330). That is, this remained angle, RWA*=A-INKA*×WINK, is set on the basis of, at least, the angle A and the number of increment INKA*. A ratio V between the remained angle RWA* and the increment width WINK is determined, and whether the remained angle is found in the first half or the second half of the increment, is shown (S340).

Abstract: PURPOSE:To reduce the influence of loading effect on the occasion of a dry- etching, by forming a dummy photo resist pattern on a part where a spacing between photo resist patterns is relatively wide, and performing the dry-etching of a film to be etched applying the photo resist pattern and the dummy photo resist pattern as a mask. CONSTITUTION:A dummy photo resist pattern 4b is formed on a part where a spacing between photo resist patterns on a film to be etched is relatively wide. In the case where a dry-etching of the exposed part of an aluminum film 30 is selectively performed applying a photo resist pattern 4a and the dummy photo resist pattern 4b as a mask, the density of a pattern containing the photo resist pattern 4a and the dummy photo resist pattern 4b is made uniform, and so the plasma condition becomes uniform for the photo resist pattern 4a and the dummy photo resist pattern 4b. Thus the influence of loading effect is reduced, so that an aluminum wiring patterns 30a, 30b which have dimensional accuracy and contains no undercut can be formed on a base insulating film 2.

Title: Connector
Inventor: HASEGAWA TERUAKI
IPC: H01R13/64
Filed: 1999-02-16
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of a detecting member projecting from a connector housing to enhance operability. SOLUTION: In this connector, a detecting member 20 is displaced toward a flexible space 13 of a lock arm 11 to detect a fitting state after fitting. At this time, the detecting member 20 is displaced between a waiting position and a detecting position along an arc path so that the displacement path is elongated compared with the displacement linearly displacing the distance between these positions and an operator can really feel the detecting operation. When the detecting position is set on a fixed position and the distance along the displacement path between these positions is determined, the displacement path is shortened compared with the linear displacement path so that the amount of the projection of the detecting member 20 projecting from a connector housing 10 can be reduced when the detecting member 20 is projected from the connector housing 10 on the waiting position.

Abstract: PURPOSE:To make it possible to reduce the size of a space and make the best use of an indoor space, by accommodating a cooling air unit in a place behind a wing drawer of a desk which can prevent an increase in an occupancy space of a desk and cooling air unit. CONSTITUTION:When electricity is supplied to a cooling air unit 8, a blower 7 is rotated. A cooling air 11, which has been cooled passing through an evaporator 4, is discharged from a cooling air blowout port 10 installed to a top board 9, thereby forming a cooling air zone 12 which envelops a work space. Generally, the depth of a wing drawer desk 1 is shorter than the depth of a wing drawer 2, which often produces a dead space behind the wing drawer 1. The cooling air unit 8 is installed to the dead space while the cooling air discharge port 10 is installed to the top board 9. This construction makes it possible to accommodate the cooling air unit 8 or the like without the sacrifice of the intrinsic function of a desk and moreover without an increase in an occupancy capacity of a desk 1.

Title: Ignition system for engine
Inventor: YOSHINAGA TOORU
IPC: F02P15/10
Filed: 1980-03-25
Abstract: PURPOSE:To prevent unnecessary consumption of an ignition plug in an ignition system for effecting continuous ignition for a predetermined while, by stopping the continuous ignition at a predetermined crank position. CONSTITUTION:Output of an oscillation circuit 61 is transmitted to an igniting means for causing continuous ignition for a while determined by a timer circuit 113 from a reference angle detected by a vacuum-controlled electromagnetic pickup 40b. When a pulse is produced by an electromagnetic pickup 40a, continuous ignition is stopped by resetting an RS flip-flop 114, if a timer setting time is not passed. Since, with such an arrangement, the time period for keeping continuous spark discharge of an ignition plug can be controlled to be minimum by both of the timer circuit and a circuit for controlling the crank angle position where the continuous ignition is to be stopped, consumption of electric power can be reduced and use of the ignition plug can be minimized.
