Title: Air-fuel ratio feedback control method for internal combustion engine
Inventor: AKIYAMA EITETSU
IPC: F02D41/00
Filed: 1987-01-30
Abstract: PURPOSE:To prevent a fluctuation in an r.p.m. in idling, by making a reference value in air-fuel ratio feedback control larger than a normal value when an automatic transmission is in a drive range to make an air-fuel ratio rich. CONSTITUTION:An electronic control unit 5 calculates a basic amount of fuel injection based on values sensed by a suction gas absolute pressure sensor 8 and an r.p.m. sensor 10 and compares a value sensed by an O2 sensor 13 with a reference value for effecting feedback control of an air-fuel ratio by proportional integral control. The electronic control unit 5 determines whether a speed change position of an automatic transmission is in a drive range. When it is in the drive range, the electronic control unit 5 makes the reference value large to make an air-fuel ratio rich.

Title: Rubber mold stress cone
Inventor: MORISHITA SHINYA
IPC: H01B1/24
Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To obtain a rubber mold stress cone exhibiting sufficient conductivity and long term stabilized performance while reducing the quantity of carbon black to be added by forming the stress cone through cross-linking of a rubber composition obtained by adding a specified parts weight of ketjenblack to a base polymer, i.e., an ethylene propylene rubber composition. SOLUTION: 5-25 pts.wt. of ketjenblack is added to 100 pts.wt. of base polymer, i.e., an ethylene propylene rubber composition, to produce a rubber composition which is then crosslinked to form a stress cone. When less than 5 pts.wt. is added, insufficient conductivity is imparted and when more than 25 pts.wt. is added, flexibility can not be attained. JIS-A6 hardness is set at 40-54 after cross-linking. When the hardness deviates from this range, ideal adhesion can not be attained on the interface. A rubber mold stress cone is formed by molding insulation layers 1, 2 of insulating rubber and conductive rubber while making a cable insertion hole 3.

Title: Stationary induction electric apparatus
Inventor: KIUCHI KAZUYUKI
IPC: H01F27/28
Filed: 1984-02-10
Abstract: PURPOSE:To reduce a noise level and make easy the transportation of the titled device by such an arrangement that the windings facing to the tank wall are connected so that the lower side of tank becomes low voltage, reducing the size of insulator between the tank and lower windings and providing a noise shielding wall at the side surface of lower side of tank. CONSTITUTION:In a large capacity transformer, a high voltage winding 17 is connected directly to the ground system. Therefore, the multistage insulation system is employed for the insulation of such transformer and the neutral point terminal O is set to the lower insulation class as compared with the line terminal U. For example, in case the line terminal U is set to #200, the neutral point 0 is set to #60. The required insulation size for winding 17 and wall of tank 1 is determined by the potential of winding. Therefore, with such connection as shown in the figure, the insulation size D in the side of neutral point (low voltage side) can be set smaller than the size C between the wiring 17 and wall of tank 1 at the line end. Employment of such high voltage winding structure makes it possible that the lower side of insulation size between the winding 17 and wall of tank 1 can be reduced smaller than the upper side of winding. Thereby, a side plate of tank 1 can be moved near to the side of winding 17 by bending the plate only by the size E and a noise shielding wall 24 can be provided in such space.

Title: Production of toner particles
Inventor: NEGISHI HIROAKI
IPC: G03G9/087
Filed: 1989-01-31
Abstract: PURPOSE:To obtain powder not contg. fine particles at all and regulated to the same particle size by fusing fine particles into the surfaces of coarse particles by compression and intense friction in the gap between the surface of the inner wall of casing and a barrier member. CONSTITUTION:In a friction pulverizer for treating a kneaded compsn. passed through a pulverizing stage, a violent swirl is generated in casing 3 by rotating the casing 3 at a high speed and toner powder charged into the center of the casing 3 is pressed against the surface of the inner wall of the casing 3 by centrifugal force and whirled together with the inner wall. By this violent whirling motion, the toner powder is compressed by a barrier member 5 and the surface of the inner wall of the casing 3 and the compressed powder is further compressed in the gap between the peripheral end surface of the member 5 and the surface of the inner wall of the casing 3. At the same time, intense friction is caused, the surface of the toner powder is softened and the flowability is increased. Fine particles are fused into the surfaces of coarse particles and spherical particles hardly contg. fine particles which are contained before treatment and regulated to much the same particle size are obtd. Unlike heat treatment, this treatment prevents the coarse particles from melt-bonding to each other.

Abstract: PURPOSE:To prevent intergap corrosion in a screw fitting of high-alloy oil well pipes containing over a specified amount of Cr in wt.% by covering the pipe end to be directly exposed to corrosive environment, incl. the seal surface, with a non-metal layer in a certain thickness. CONSTITUTION:In a screw fitting of high-alloy oil well pipes 2, 2a containing over 7.5% Cr by weight, the portion from the internal surface 3, 3a to the seal surface 1 exposed to internal corrosive environment is covered with a non-metal layer of 1-100 mum thick.

Examples of material to this non-metal layer are TiO2, Al2O3, ZrO2, Cr2O3, TiN, AlN, ZrN, BN. TiC, and ZrC. Consequently the outflux of metal ions is suppressed even in the environment at high temp., under high pressure, and with H2S, CO2, Cl<->, to lead to prevention of intergap corrosion.

Abstract: PROBLEM TO BE SOLVED: To provide a divided-type bilge keel capable of being easily changed by easily replacing a part, and a small boat having it. SOLUTION: In this small boat, bilge keels 4 are longitudinally attached to right and left sides 2a of a hull 2. In this case, the bilge keels 4 are a divided type and constituted of a base 4A longitudinally attached to right and left sides 2a and fins 4B detachably attached to the bases 4A.
