Abstract: PURPOSE:To prevent supercharging drift by open-loop-controlling the control quantity based on the learning value of the correction value when the supercharged pressure is in the transient state in controlling a supercharged pressure control means with the control quantity corrected by the correction value dependent on engine operation parameters. CONSTITUTION:A variable-capacity turbo charger 5 has a movable vane to adjust the flow area on the turbine casing side, the movable vane is driven by a diaphragm type actuator 60. When the pressure introduction into two pressure chambers of the actuator 60 is controlled by a control means C via solenoid control valves 69 and 72, the control quantity is feedback-controlled in response to the variation between the actual supercharged pressure and the target supercharged pressure when the supercharged pressure is stationary. The correction value applied during this control is calculated to obtain the learning value, the control quantity is open-loop-controlled based on the learning value of the correction value when the supercharged pressure is in the transient state. If preset conditions are satisfied in the stationary state, the above learning is prohibited.

Title: Deodorizing device
Inventor: KATO TAKEICHI
IPC: B01D53/34
Filed: 1993-11-30
Abstract: PURPOSE:To provide a deodorizing device removing unpleasant odor and to suppress a discharge of dust. CONSTITUTION:In the deodorizing device, a gas to be treated which is incorporated to a device 1 is sent to an upper part of the device, and after removing the dust by a filter layer 2, the gas is allowed to flow to a lower part together with a deodorizing liq. dispersed from a spray nozzle 3. At this time, the gas to be treated is brought into contact with the deodorizing liq. and the gas to be treated is deodorized, but because both fluids flow in parallel, a gas liq. contact efficiency is inferior as compared to a counterflow method. Thereby, a gas liq. reaction layer 4 is provided at the lower part of the spray nozzle to accelerate the contact of both fluids. In this way, the structure is simplified and miniaturized, so a plant investment becomes inexpensive. Large bulk of dust and unpleasant odor are removed simultaneously. Because a palverized coal, etc., can be used at the gas-liq. reaction layer 4, the running cost is inexpensive.

IPC: B41J2/485
Filed: 1992-12-07
Abstract: PURPOSE:To obtain a bit map image of good quality for a character consisting of plural arrayed strokes by reproducing intervals between strokes faithfully to the original design as to a method and device for character generation which expands an outline character, represented on a logical coordinate system, on physical coordinates represented with integer values. CONSTITUTION:After outline font information obtained by representing the outline of the character with coordinates is converted into coordinate values of a coordinate system of a specified size, a process for rounding them into integer coordinate values is performed and the bit map image of the character of the specified size is generated. This character generating method calculates conversion magnifications of respective intervals between strokes of a character having plural strokes of the same kind from the intervals between the strokes before and after the rounding process and moves the coordinates of the strokes having the stroke intervals so that the difference between the maximum magnification and minimum magnification among the conversion magnifications becomes small.

Title: Gel-sealed semiconductor device
Inventor: TATE HIROSHI
IPC: H01L23/29
Filed: 1987-12-25
Abstract: PURPOSE:To prevent bonding wires from breaking thereby manufacturing a semiconductor device in enhanced roliability by a method wherein a gel is blended with a filler. CONSTITUTION:An applicable photoset gel 7 is blended with a filler 8 to control the phototransmissivity of the gel 7. When the surface of the gel 7 blended with the filler 8 is irradiated with light, the gel 7 is to be set but as the light is carried further inward, the light is absorbed into or reflected on or shielded with the filler 8 to change the percentage of irradiation with the light. Consequently, the surface of the gel 7 irradiated with ample light is set rather rapidly but the deeper the layer of the gel 7, the less light reaches there making the deeper layer soft. Through these procedures, the improvement of the resistance to external force (shock, centrifugal force), the decrease in stress on bonding wires 4 resultant from the thermal expansion and contraction of the gel 7 can be assured thereby enhancing the reliability of the semiconductor device.
