Title: Preparation of 5-isopropyl-bicyclo(3,1,0)hexane derivative
Inventor: NAGAKURA AKIRA
IPC: C07D301/02
Filed: 1978-01-31
Abstract: PURPOSE: To obtain the title substance useful as a raw material for the synthesis of perfumes, by reacting 3-isopropyl-2-cyclopentenone with dimethyloxosulfonium methylide in on aprotic solvent.  
     CONSTITUTION: 3-Isopropyl-2-cyclopentenone (P) of formula I is reacted with an equimolar amount of dimethyloxosulfonium methylide (D) in a nonionic solvent, e.g. dimethyl sulfoxide, DMF, dioxane, or THF, to give 5-isopropyl-biscyclo [3,1,0] hexane-2-one of formula II. Two moles of D per mole of P give spiro (5-isopropylbicyclo [3,1,0] hexane-2,2-oxirane) of trans form of formula III and that of cis- form of formula IV at a ratio of (III) to (IV) of about 6:4.

Title: Light emitting device
Inventor: KAWASUMI TAKAYUKI
IPC: H01S5/323
Filed: 1997-01-22
Abstract: PROBLEM TO BE SOLVED: To prevent doped impurities from being diffused into an active layer to suppress the deterioration of the active layer caused by the diffusion of impurities and thereby lengthen the life of a device, by forming a layer having a lattice unconformity between the active layer and an impurity doped layer. SOLUTION: In a semiconductor laser 1, a diffusion preventive layer 9 having a lattice unconformity is constituted of alternately stacked compression strain layers and tensile strain layers. Due to this structure, zinc doped into a second conductivity-type clad layer 10 is prevented by the diffusion preventive layer 9 from being diffused into an active layer 5, and zinc does not enter the active layer 5. Therefore, the interstitial diffusion of zinc in the active layer 5 can be prevented and thereby the deterioration of the active layer can be suppressed and the life of the semiconductor laser 1 can be lengthened, resulting in the increase in the reliability of the semiconductor laser 1. By this method, there is no necessity of caring about the diffusion of zinc into the active layer 5 and, therefore, the degree of freedom of doping profile of zinc can be expanded.

Title: Electrophotographic copying machine
Inventor: TAKEDA MAKOTO
IPC: G03G15/02
Filed: 1985-01-21
Abstract: PURPOSE:To attain size reduction and simplification by charging an image formation surface in the 1st turn and transferring a visible image formed on the image formation surface to transfer paper in the 2nd turn. CONSTITUTION:Corona ions having the opposite polarity of charges of toner are given to the reverse surface of transfer paper supplied from a paper feed cassette 9 at a transfer position by an electrostatic charging device 8 to charge the reverse surface electrostatically, and a toner image is transferred to the transfer paper 10. A beltlike photosensitive body from which the transfer paper 10 is separated enters the 2nd turn and reaches the installation position of an exposure device 3 again. At this time, its residual potential is held high because the use of a separating electrode, etc. is omitted. For the purpose, electrostatic discharging is performed by using the illumination lamp 3a of the exposure device 3. Thus, the copying process is completed in the two-turn process, so the copying machine is reduced in height and unnecessary space is removed.

IPC: B60L50/16
Filed: 1998-01-21
Abstract: PROBLEM TO BE SOLVED: To perform a gear shift without using a clutch by employing a mechanical transmission using ordinary gears. SOLUTION: A mechanical transmission having a plurality of gears and a neutral point is arranged between a main electric motor for running and a drive wheel, and the rotation speed of a drive wheel (a drive shaft) and the rotation speed of a main electric motor are detected. When the main electric motor is run under no-load at a step 1 and brought into a non-load running, a transmission is released from engagement of the gear of a transmission and transfer to a neutral point is effected at step 2→3. The rotation speed of the main electric motor is controlled at a step 4. When two rotation speeds are approximately synchronized with each other, the gears are engaged with each other and a gear shift is executed at a step 5→6.

Title: Production of homogeneous steel material
Inventor: KUBOTA TAKESHI
IPC: C21D8/00
Filed: 1981-01-26
Abstract: PURPOSE: To eliminte the segregation of contained elements formed during casting and to form a homogeneous steel material by subjecting an ingot or slab of steel to primary hot working in a specific temp. region then holding the same at above specific temp.  
     CONSTITUTION: An ingot or slab is subjected to primary hot working of ≥20% reduction of area in an austenite temp. region of 1,200°C or below or an austenite-ferrite two phase coexistence temp. region between Ar 1  temp. and Ac 3  temp. Thence, it is reheated to above the primary hot working starting temp. and is held at 1,000°C or above for ≥30min. By this treatment, segregation elements diffuse thoroughly. In succession to this, secondary hot working can be  accomplished. When the coarse austenite crystal grains of steel are formed by  the heating stage, it is possible to restore toughness by holding the ingot for  ≥30min at 1,000°C after the primary hot working or cooling the ingot after the  secondary hot working once to the Ar 1  temp. or below, thence again reheating  the same to the Ac 3  temp.

Title: Locomotive insulation monitor
Inventor: JELIC SAVO
IPC: H02H3/00
Filed: 2004-03-17
Abstract: The MKI insulation monitors are intended for use in electric locomotives and are designed to protect against ground faults. In application field there are all electric locomotives and multiple-unit sets. Way of operation: The monitors induce a low DC voltage, low current on traction motor windings & supply circuits. The measuring circuit is closed via ohmic insulation faults. The monitor continuously calculates circuit resistance to ground – should the resistance fall below predeterminated levels, the monitor activates alarm (first, warning level) and contacts prohibiting the circuit to be energized (second, acting level). Activating alarm the monitor gives early warning about insulation degradation before motors with deteriorated insulation are in immediate danger of failing on start up. This allows preventive maintenance to be scheduled when convenient, thus eliminating failure and the need for an emergency replacement or rewind. The monitoring of insulation is permanent, so locomotive insulation monitor is on-line and off-line monitoring device.

Title: Refractory metal and alloy refining by laser forming and melting
Inventor: AIMONE PAUL R
IPC: C23C14/34
Filed: 2003-01-22
Abstract: A process to chemically refine and consolidate tantalum, niobium and their alloys to a fabricated product of net shape or near-net shape with higher throughput, more consistency, and lower manufacturing costs compared to prior art routes or rejuvenate damaged and deteriorated refractory metal parts. Powder metal is loaded into hoppers to be fed into laser forming/melting equipment. A suitable substrate is loaded into a laser forming/melting chamber onto which the powder will be deposited and consolidated in a point-scan process. As the powder is fed onto successive points of the surface of the substrate in linear traces, the laser is used to heat and partially melt the substrate and completely melt the powder. A combined deposition and melt beam traces the substrate surface repeatedly over a selected area to build up a dense coating of controlled microstructure in multiple layers. A fully dense deposit is built up that becomes the desired shape.
