Title: Engine speed controlling apparatus
Inventor: SHIMOMURA SETSUHIRO
IPC: F02D41/16
Filed: 1982-05-14
Abstract: PURPOSE:To prevent unstable control of the engine speed at the transient period when the engine operation is shifted to idling operation, by determining the time for starting feedback control of the engine speed at said transient period through detection of the negative pressure in an intake pipe. CONSTITUTION:An arithmetic unit 11 is furnished with an output (a) of a throttle switch 6, an output (b) of a pressure sensor 7, an output (c) of an engine- speed sensor 9 and an output (d) of a desired engine speed setter 10 and produces an opening and closing signal (e) for executing duty control of a solenoid valve 4 disposed in a by-pass passage 5. The quantity of air passed through the by-pass passage 5 is controlled according to the duty of the opening and closing signal (e). By detecting rapid deceleration from the fact that the negative pressure in an intake pipe becomes fairly higher than the normal negative pressure at the time of rapid deceleration, stall of an engine is prevented by prohibiting starting of feedback control of the engine speed when the negative pressure becomes higher than the operation pressure of the pressure sensor 7.

Title: Engine with turbosupercharger
Inventor: OKIMOTO HARUO
IPC: F02B39/00
Filed: 1984-04-23
Abstract: PURPOSE:To introduce steam generated in a turbosupercharger into an intake air cooler and prevent a trouble due to a pressure rise of water after an engine is stopped, by arranging the intake air cooler in a higher position than the turbosupercharger and connecting both of them through a cooling water passage extending upward. CONSTITUTION:An intake air cooler 4 cools intake air supplied to the main unit 2 of an engine from a turbosupercharger 3 through an intake pipe 5, and the engine arranges the intake air cooler 4 in a higher position than the turbosupercharger 3, providing a cooling water passage 10b, which connects both of these intake air cooler and turbosupercharger, to be extended to the intake air cooler 4 from the turbosupercharger 3 so that the cooling water passage 10b in its half way may eliminate a part, which exists in a side of the turbosupercharger 3, in a higher position than the part which exists in a side of the intake air cooler 4. In this way, the engine enables an air bubble to be introduced and reservoired in the intake air cooler 4 through the cooling water passage 10b even when cooling water in a water jacket boils by accumulated heat of the turbosupercharger 3 generating the air bubble after the engine is stopped. Accordingly, the cooling water passage 10b or the like can be easily prevented from bursting and/or breaking when the pressure of water rises.

Title: Forming method for connecting rod in internal combustion engine
Inventor: YAMAGATA YUTAKA
IPC: F16C7/08
Filed: 1986-04-09
Abstract: PURPOSE:To improve fatigue strength of a connecting rod, by forming a cylindrical material into a truncated cone shape next folding both ends of the material at a right angle to swell base part sides of each folded end to an opposite side to the free end and quenching the material to be carburized. CONSTITUTION:A connecting rod 1 is constituted of a big-end part 4, small-end part 7 and a connecting rod main unit 8. The connecting rod main unit 8, in which a cylindrical material 11 of low carbon steel is formed into a truncated cone shape, forms the first intermediate article 12. Next the first intermediate article 12 folds its both ends to be curved at a right angle, forming these folded ends 13 into a protruding amount of predetermined dimensions, thereafter the first intermediate article 12, whose intermediate part is formed into a box shape of rectangular section, forms the connecting rod main unit 8. While base part sides of the folded ends 13 are swollen in an opposite side to the free end, and after a protruding end 20a of a swollen part 20 is cut off, carburization quenching is performed. As the result, of the cylindrical bodies in the both end parts, the connecting rod uses the body of larger diametric size for the big-end part while the body of smaller diametric size for the small-end part.

Title: Input device for circuit diagram
Inventor: KURODA HIROTAKA
IPC: G06F17/50
Filed: 1989-03-31
Abstract: PURPOSE:To easily confirm the presence or absence of diaphragm symbols having the same function and different forms by showing whether the diaphragm symbols retrieved by a diaphragm symbol retrieving means and displayed and the diaphragm symbols having the same function and different forms are stored in a storage means or not. CONSTITUTION:An operator operates a mouse 4 to instruct the input of a retrieving command displayed at a command display part 15. At the same time, the operator operates a keyboard 2 to input the name of a diaphragm symbol to be retrieved. A control part 1 retrieves the diaphragm symbol corresponding to the input name and reads the symbol out of a library file 3. Then the part 1 displays the diaphragm symbol at a retrieved diaphragm symbol display part 11 when other diaphragm symbols having the same function and different forms are not detected. Then an instruction is produced with operation of the mouse 4 for input of the command displayed at an arrangement command display part 17. Thus the part 1 copies the diaphragm symbols displayed at the part 11 to a diaphragm symbol arrangement part 12 and arranges these symbols. This operation is repeated to arrange the desired diaphragm symbols at the part 12 for production of a circuit diaphragm.

Filed: 1986-04-10
Abstract: PURPOSE:To stabilize a current characteristic against the fluctuation of a load and that of a power source voltage by constituting a circuit utilizing the difference between action points of the same conductive type field effect transistors. CONSTITUTION:If the threshold VT1 of the 1st FET31 is higher than that VT2 of the 2nd FET32, the action point of the 1st FET31 can be set within the saturated area of a drain current. Accordingly a change in the drain current of the 2nd FET32 can be suppressed. The 1st and 2nd FETs 31 and 32 are integrated in more than two areas, and an impurity layer made of material different from a substrate is provided as a means to change an element characteristic. Elements are integrated in an impurity layer area, and their characteristics can be changed independently. Thus the constant current circuit with a stable current characteristic can be obtained.

Title: Exhaust gas purification catalyst
Inventor: ARAKAWA KENJI
IPC: B01J29/26
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To purify NOx discharged from an internal combustion engine efficiently especially in an oxygen-excess atmosphere by using zeolite containing trivalent or tetravalent manganese as an exhaust gas purification catalyst. SOLUTION: By zeolite containing trivalent or tetravalent manganese, NOx discharged from an internal combustion engine is removed in a low HC concentration in which an HC/NOx ratio is not greater than 5. This catalyst is obtained by a method in which Na-type ZSM5 slurry 23.8 in silica/alumina ratio is added with manganese nitrate, agitated under heating, filtered, washed, dried, and baked. The valence of manganese contained in the catalyst is a mixed valency of trivalent and tetravalent. The catalyst is molded and crushed to obtain pellets, and the activity is measured. In this way, when NOx discharged from an internal combustion engine is removed especially in an oxygen- excess atmosphere, high NOx purification performance is obtained in a low HC quantity of 5 or less.

Abstract: PURPOSE: To make possible efficient removable of polluted matter deposited on capillary forming materials by providing the purifier of the specific construction to the curving top of an inverted J-form syphon packed with capillary forming materials.  
     CONSTITUTION: When polluted matter is subjected to capillary osmosis filtration in an inverted J-form syphon pipe 1 packed with capillary forming materials 2 and compressed air is supplied from pipe 12 into a stagnating chamber 6 after this, then a float 10 is pushed up and the air of high velocity flows in the syphon pipe and wipes away the polluted matter having been deposited. Next, when water or washing liquid is supplied from pipe 13, it flows into the syphon and substitutes the air as in the case of air. At this time, the air having been forced up to the curving top 3 of the syphon pipe passes through a fine bypass tube 9 and forces up stoppers 21, 20, whereby it is released into the atmosphere from a water sealing tank 8. When a gate valve 15 is closed upon completion of rinsing, syphon effect acts in the syphon pipe and becomes a negative pressure, thereby perfectly shutting off the apparatus 4.
