Title: Exhaust emission control device for internal combustion engine
Inventor: OGISO TAKEO
IPC: F01N3/18
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To prevent unburnt HC and CO from being blown off in the atmosphere by controlling the air-fuel ratio of exhaust gas flowing in an NOx absorbent so that a rich degree is gradually reduced after being made rich when NOx must be blown off from the NOx absorbent arranged in an exhaust passage. SOLUTION: An NOx absorbent 17 interposed in an exhaust pipe 16 absorbs NOx when the air-fuel ratio of exhaust gas is rich, and blows off the absorbed NOx when the oxygen concentration in the exhaust gas reduces. An air-fuel mixture is rich, and when the air-fuel ratio of the exhaust gas becomes rich, unburnt HC and CO exhausted in large quantities from an engine are oxidized by reacting with oxygen on platinum Pt. The oxygen concentration in the exhaust gas extremely reduces, and when NO2 is blown off from the absorbent 17, the NO2 is reduced by reacting with the unburnt HC and CO, but in this case, a rich degree of the air-fuel ratio of the exhaust gas is gradually reduced, and is maintained in the theoretical air-fuel ratio for a prescribed period, and the unburnt HC and CO are prevented from being blown off in the atmosphere.

IPC: F23C10/02
Filed: 1987-06-30
Abstract: PURPOSE:To facilitate the delivery of dense bed material and miniaturize the belt conveyer by disposing the belt conveyer between the feed opening under a combustor and the dense bed material storage area, and mixing the dense bed material with powder material, which mixture is then delivered to the feed opening by the belt conveyer. CONSTITUTION:Granular dense bed material such as alumina ball is mixed with powder material to form a mixture 27, and said mixture 27 is delivered to a supply pipe 11 by a belt conveyer 26. Alumina balls 29 are separated from the mixture 27, as needed, by means of a sifter 30, and only alumina balls 29 are supplied as the dense bed material 7 through a supply pipe 11 into the combustor 1. Therefore, even though the dense bed material is granular, the powder material acts as the retainer for the dense bed material to allow the same to be supported on the top of the belt conveyer 26, permitting the inclination of the belt conveyer 26 to be relatively greater. As a result, the belt conveyer can be miniaturized, and the manufacturing and operating costs can be reduced.

Title: Thermal recorder
Inventor: KUMA NORIHIRO
IPC: B41J2/36
Filed: 1991-07-02
Abstract: PURPOSE:To perform thermal recording in different recording density modes from low temperature environment to high temperature environment. CONSTITUTION:A control circuit 6 reads out correction values from a dot correction table (a) 20 and a period correction table (b) 2 depending on the amount of information for driving a thermal head. When the recording density is in super fine mode, correction values are read out from a temperature correction table (c) 22 whereas when the recording mode is standard fine mode, correction values are read out from a temperature correction table (d) 23. Strobe width is then operated according to a following formula using each correction value. Strobe width=Dot correction value+period correction value-temperature correction value. A strobe signal having thus determined strobe width is then generated from a driving circuit 17 and the driving time of the heating element in thermal head 16 is limited thus performing stabilized recording of image information onto a thermal recording paper.

Title: Inserting method of electronic component
Inventor: IMANISHI MAKOTO
IPC: H05K3/12
Filed: 1988-06-29
Abstract: PURPOSE:To delete steps from adhering of conventional Cu foil to coating of solder and to remarkably shorten a lead time by forming a pattern on a board by using conductive paste having adhesive properties on a conductor. CONSTITUTION:A nozzle 4 is fed back with height by a signal of a noncontact height measuring unit 5, discharges conductive paste 2 having adhesive properties while maintaining an interval between a board 1 and the nozzle 4 constant, and forms a circuit pattern. According to this nozzle discharging system, the pattern can be formed only by the formation of NC data. Thus, a lead time can be largely shortened as compared with a screen printing. Since the paste 2 in the nozzle 4 is sealed, a solvent is not volatilized, and the life of the paste 2 is remarkably longer than that of the paste on the screen. A conventional chip mount can be applied as it is. Further, the positional accuracy of an electronic component 3 is satisfactory as compared with a solder reflowing type of a conventional example. Since no solder is employed, an improper soldering is eliminated, and the correspondence to a small component can be improved due to high density.

Title: Bonder for semiconductor device
Inventor: OKAMURA TETSUO
IPC: H01L21/60
Filed: 1990-06-20
Abstract: PURPOSE:To secure the condition of fixing the lead of a semiconductor device by moving the presser foot at the lead side in agreement with the wiring direction and by pressing only a lead to be bonded. CONSTITUTION:When wiring starts, a change-direction rotary member 5 turns and a capillary 2 moves to a bonding position at the lead side. When the capillary 2 reaches the bonding position at the lead side and starts to lower, a driving cylinder 4 acts to lower a presser pallet 3 to press the neighborhood of the bonding position for a lead 11. At the same time when the capillary 2 that completed bonding at the lead side moves up, the presser pallet 3 is lifted, thereby turning the change-direction rotary member 5 to indicate the next bonding position at the lead side. The bonder calculates a wiring direction to determine a stop position for the change-direction rotary member 5. In this way, only individual leads on which bonding is to be executed can be pressed, leads can be fixed perfectly, thereby being able to promise bonding stability.

Filed: 1988-06-29
Abstract: PURPOSE:To enhance the fundamental capacity of a recording apparatus by performing control so that the stop and reopening of the driving of the recording apparatus is performed at slightly lower temp. when the temp. rising rate of a unit is high whereas performed at slightly higher temp. when the temp. rising rate is low. CONSTITUTION:When the recording of an image whose black part is relatively scarce is continued, the temp. of a unit 2 rises gently. Since the difference outputted from a difference circuit 12 does not exceed T3 in this temp. rising rate, a signal SW is in an OFF-state. When the temp. value TEMP detected by a temp. detector 3 becomes higher than a set temp. value T1a, a comparing circuit 7 turns an output signal ON and a recording pulse generation circuit 6 generates no recording pulse and the driving of a heating resistor element 1 is stopped. When the recording of an image rich in a black part is continued and the temp. value TEMP exceeds a set temp. value T1b, a comparing circuit 8 turns on output signal, that is, a signal STOP ON to suppress the generation of a recording pulse and stops the driving of the heating resistor element 1.
