Title: Linear motor
Inventor: TAKIGAWA TOSHIAKI
IPC: H02K41/02
Filed: 1992-08-07
Abstract: PURPOSE:To lessen a current density in the central part of a stator core with a magnetic flux density-made uniform, to suppress a rise in temperature and thereby to make it uniform by a method wherein the depth of winding slots of the core are made larger in the central part than in the opposite end parts, while core backs are made uniform, and the wire size of a stator winding is made larger in the central part than in the opposite end parts. CONSTITUTION:The depth of slots in the central part of a stator core 2 is made larger than the depth of three slots in each of the opposite end parts of the core, and dimensions of a core back A in the opposite end parts and a core back B in the central part are made the same. The wire size of a stator winding 4b in the central part is made larger than the wire size of a stator winding 4a of the three slots in each of the opposite end parts. By this method, the current density of the stator winding 4b in the central part is lowered in comparison with the one of the stator winding 4a in the opposite end parts and thereby generated loss is reduced, while magnetic flux densities in the core backs A and B are kept uniform. Besides, a rise in temperature in the central part is suppressed, the rise in temperature in the opposite end parts and the central part is made uniform and thus a local rise in temperature can be prevented.

Title: Semiconductor device
Inventor: HARA TOMOOKI
IPC: H01L29/732
Filed: 1988-08-24
Abstract: PURPOSE:To obtain a semiconductor device capable of increasing the operation speed of I<2>L without decreasing betaVCEO of an ordinary bipolar transistor by providing a second buried layer of one conductivity type which is formed in a region just under a lateral transistor on a first buried layer in a second island, and is in contact with a third region. CONSTITUTION:A first buried layer 2 of N<+> type with 10-30OMEGA/square is formed by diffusing, e.g., Sb or As from the surface of a P<-> type substrate 1. A second buried layer 3 of P-type with 0.1-1kOMEGA/square is formed by diffusing or ion-implanting impurity whose diffusion coefficient is larger than the impurity which formed the first buried layer 2, e.g., B or BCl3, from the surface of the first buried layer of a region just under a lateral PNP transistor of I<2>L part. Since the second buried layer of P-type is formed, in this manner, on the first buried layer of N<+> type in a region just under the lateral PNP transistor, so as to be in contact with the first base region of P-type, hole injected from an injector region contributes to collector current not only in the lateral direction, as the conventional manner, but also in vertical direction. As a result, alphaPNP is increased and a device of low power consumption is realized.

Title: Recovery and regeneration of palladium salt catalyst
Inventor: ITAYA HIROSHI
IPC: B01J38/00
Filed: 1983-11-09
Abstract: PURPOSE:To recover a catalyst having good activity in good yield, by removing volatile components from an oxidative coupling reaction solution by distillation and subsequently baking the formed residue containing the catalyst while treating the baked residue with an acid. CONSTITUTION:At least Pd-salt catalyst is recovered and regenerated from a reaction solution containing biphenyl tetracarboxylate formed by the oxidative coupling of ortho-phthalic ester in the presence of a catalyst containing a Pd- salt, a copper-salt and a basic bidentate ligand. In this method, volatile components containing unreacted ortho-phthalic ester and biphenyl tetracarboxylate are separated from the aforementioned reaction solution by distillation while the obtained distillation residue is baked at 400-600 deg.C and thus obtained baked substance is treated with an acid such as ritric acid. As a result, the lowering in the yield of the oxidative coupling reaction product is prevented and the regenerated catalyst shows good catalytic activity.
Patent JP-H0494214-A (JP)
Title: Transmission circuit for logic signal
Inventor: SATO TOSHIRO
IPC: H03K19/0175
Filed: 1990-08-09
Abstract: PURPOSE:To transmit a logic signal excellently even when a termination of a transmission line is opened by connecting the other end of the transmission line whose one end is opened to the emitter of an emitter follower transistor(TR), driving the transmission line via the emitter follower TR with a logic signal and connecting plural LSI logic circuits in parallel on the way of the transmission line. CONSTITUTION:LSI(2)-LSI(n) connected in parallel with a transmission line 3 whose one end is opened are logic circuits each having a gate circuit as an input circuit and each input resistance is regarded in terms of DC as infinite. For example, when the signal of an ECL level inputted to an emitter follower transistor 8 is changed from a high level to a low level, while a current flowing from the emitter of the emitter follower transistor 8 is decreased, since a constant current TR 9 is acted in the constant current operation, a current based on the charge stored in a wiring capacitance is caused by being discharged by the constant current TR 9. Thus, even when the termination of the transmission line is opened, the switching waveform from the high level to the low level is improved. Thus, even when the termination of the transmission line 3 is opened, the LSI logic circuits are correctly operated uniformly.

Title: Opening and closing valve
Inventor: ISHIKAWA KAZUNORI
IPC: F16K15/04
Filed: 1984-10-09
Abstract: PURPOSE:To effectively prevent damage on the surface of a valve body and ensure its sealing characteristic when a valve is closed, by extending an end, in the side adapted to the valve body, of a coil spring wire rod so as to prevent the end from coming into contact with the valve body. CONSTITUTION:A coil spring 3 forms in its end, in the side adapted to a valve body 2, a ring-shaped part 31 serving as a seat of the valve body 2, while the end 3A of a wire rod, being extended to the outer from an external diameter of the coil spring and positioned outside the ring-shaped part 31, is prevented from coming into contact with the valve body 2. In this way, a check valve, when it is actuated to be opened and closed, enables the end 3A of the wire rod of the coil spring 3 to be prevented from rubbing the valve body 2, preventing a surface of the valve body 2 from flawing by an edge in the end 3A of the wire rod.

IPC: G06K19/077
Filed: 1992-08-10
Abstract: PURPOSE:To obtain a modular connector requiring no thickened part by forming a cover at one end of a hole made through a planar member. CONSTITUTION:A hole 36 made through a planar member 34, especially the bottom part thereof, stops insertion of a modular jack. The inner wall 16 defines the inserting direction of the modular jack and an electrode part 24 disposed in the hole 36 establishes an electrical connection. A cover 30 for that hole stops the modular jack at a predetermined position. The cover 30 is housed in the hole 36 under closed state and allows insertion of the modular jack into the hole 36 to be engaged in place under open state. Since a modular connector 26 is constituted of the planar member 34, it can be employed in an IC card, or the like, where the thickness is limited.
