Inventor: NAGAYA KOJI
IPC: F02D1/02
Filed: 1992-04-02
Abstract: PURPOSE:To prevent failure and uncontrollability of an actuator to control a plunger prestroke amount of an in-line fuel injection pump. CONSTITUTION:A control sleeve 22 to adjust a pressure delivery starting time of fuel is provided on the outer periphery of a plunger 14 to deliver fuel with pressure. This control sleeve 22 is driven by a step motor 4 in linkage with a control rod 24, levers 62, 65, a ball coupling 60 and others. Stoppers 90, 91 integrally formed on a housing 58 of the step motor 4 regulate the revolving position of the ball coupler 60. The revolution regulation range by the stoppers 90, 91 is set within a range where a movable part to detect rotational displacement of the step motor 4 does not interfere with other members. Consequently, as the revolution range of a movable ring of an angle detection sensor built in the step motor 4 is regulated, it is possible to avoid interference with a fixed ring, and accordingly, it is possible to avoid failure of the angle detection sensor.

Title: Tool for grooving and parting and manufacture therefor
Inventor: BRASK KARL-GOERAN
IPC: B23B27/16
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To avoid complete replacement of a holder and simplify the manufacture of a blade holder having a loose clamp by inclining the upper side of a cutting insert in such a manner that when the loose clamp is moved into a recess, the chip part of the loose clamp is pressed upward. SOLUTION: A loose clamp 7 is characterized in that when the loose clamp 7 is moved backward more deeply in a recess 6, the clamp force is gradually increased. This results from that the loose clamp 7 is partially moved downward due to the inclination of the recess 7, and simultaneously the chip part is pressed upward by a contact surface 14. Thus, a very safe and strong clamp can be obtained so as to actually eliminate the danger that the cutting insert 2 is loosened by vibration. Further, full clamp can be obtained by short movement of the loose clamp 7.

Abstract: PURPOSE: To prevent shortcircuit between a collector and an emitter, as well as to reduce numbers of masking processes by eliminating etching operations of oxidized films from a series of processes until emitter diffusing is completed after a deep collector is formed.  
     CONSTITUTION: After an oxidized film 5 and the first nitrified film 6 are formed in sequence on a semiconductor substrate 1, unnecessary areas of these films are revomed to form a groove 7 which is treated by an oxidation treatment. Then the films 5 and 6 on active areas 4A and 4B is removed, and a multicrystal Si film and the second nitrified film 18 are formed in sequence. An opeining is made in the film 18, and N-type impurities are supplied through the multicrystal Si film 17, thus forming a deep collector 19. Then the ioxidation treatment is given to form an oxidized film 20. Leaving the film 18 only to an area that is to be used for the emitter, P-type impurities are supplied through the multicrystal Si film 17, and the oxidation treatment is given so that the exposing Si film is completely converted into an oxidized film 21. A side base area 22 is formed in this process. After the film 18 is removed, a main base area 23 and an emitter area 24 are formed in a self- aligning manner through the multicrystal Si film 17.

Title: Surface treating method of copper product
Inventor: OGUCHI HACHIROU
IPC: C23C22/00
Filed: 1978-07-05
Abstract: PURPOSE: To let copper product surfaces be always covered and protected with a patina layer despite aging of the clear layer containing patina powder by forming a Cu 2 O surface on copper surfaces then coating the clear containing patina powder.  
     CONSTITUTION: After the copper surfaces of the blank made of copper or having undergone copper plating are mechanically or chemically roughened, they are coated with an aqueous copper nitrate solution or mixed aqueous solution of copper nitrate and edible salt. At this time, a Cu 2 O film is formed on the copper surfaces of the blank, whereby the surfaces are activated to make production of patina easy. Thereafter, the clear mixed with patina powder, e.g., powder form basic copper sulfate, basic copper carbonate, etc. is coated on the Cu 2 O film. Even if the clear layer of this treated product ages and peels, the Cu 2 O film appears and produces patina extremely fast and therefore the appearance of the copper ground does not occur and the surfaces will be covered almost always with the patina layer.

IPC: F02B33/00
Filed: 1991-04-15
Abstract: PURPOSE:To provide a means for improving acceleration responsiveness at the time of cooling operation without deterioration of fuel consumption in relation to the controller of a mechanical supercharger which performs intake air temperature control by operating the supercharger during the cooling operation of the engine. CONSTITUTION:When the temperature of cooling water detected by a cooling water temperature sensor 11 is low an electronic control unit(ECU) 21 actuates a supercharger 5 even in an low load range, and makes intake temperature control pertinent to a warming condition by varing the opening of a bypass control valve 9 according to the temperature of the cooling water. The output of a throttle opening sensor 12 is differentiated by the ECU 21, so as to detect the opening speed of a throttle valve 3. When the opening speed increase beyond a specified value, bypass cotrol valve opening is decreased only for a prescribed period. Consequently, an intake air temperature is temporarily increased at the initial acceleration period, so that acceleration responsiveness may be improved due to a decrease in adhesion of injecting fuel to the port face wall.

Abstract: PURPOSE:To obtain a reformed oil which is well combustible or has a low pollution level, by introducing fuel oil and a heterogenous phase soln. into a magnetic field to separate oil and the soln. from each other by a rotor, to finely divide water and to bring oil into an excited state. CONSTITUTION:Heavy oil C from a fuel oil-introducing pipe 7 and water from a heterogenous phase soln. introducing pipe 8 are introduced and rotated by a rotor 3. They are passed through holes of porous plates 4A, 4B or a space between the porous plate 4 and a casing 2 and transferred to a discharge side. Cavitation is caused in the neighborhood of the surfaces of the porous plates 4A, 4B, and water in the heavy oil is dipsersed and finely divided by impact force. The molecular bonds of combustible material-contg. compsn. in the oil are brought into an excited state which is easily dissociated, by high pressure and high temp. E.M.F. is produced in the oil and water by high-speed rotation so that the excited state is increased. Eddy current is generated by the rotor made of iron and hence, heat is generated. The temp. of the oil is elevated by this heat together with heat generated by cavitation, whereby the viscosity of the oil is lowered. The reformed oil is discharged through a discharge pipe 9 and fed to a boiler, an oven, etc.
