Title: Apparatus for detecting rotary position
Inventor: ICHIKAWA WATARU
IPC: G01B7/00
Filed: 1985-08-26
Abstract: PURPOSE:To contrive to miniaturize a rotor part and to simplify processing, by providing a stator part equipped with a winding means and the rotor part relatively rotatable and displaceable to said stator part and arranging a conductor to said rotor part. CONSTITUTION:A stator part 1 contains pole parts 1A-1D and primary and secondary windings W1, W2 are wound around each pole part. A rotor part 2 is arranged within the space surrounded by the end parts of the pole parts 1A-1D. The rotor part 2 has a cylindrical substrate 2a and a conductor pattern 2b provided to the side surface thereof. An eddy current flows corresponding to the approach degree of the pattern 2b to the magnetic field of each of phases A-D and the change in magnetic resistance due to the loss of the eddy current is generated in the magnetic circuit of each phase. Therefore, the AC signal corresponding to the angle of rotation of the rotor part 2 is induced in the windings W2 of the phases A-D. Because the eddy current has a property flowing to the vicinity of the surface of the conductor, the pattern 2b requires no large thickness. That is, the pattern 2b of the thin conductor part can be easily formed to the substrate of the rotor part 2 by surface processing treatment technique such as plating.

Title: Alkaline zinc storage battery
Inventor: NOGAMI MITSUZO
IPC: H01M4/66
Filed: 1984-09-05
Abstract: PURPOSE:To maintain zinc used as the negative active material in adequately close contact with the current collector by performing tin plating on a base plate consisting of either a nickel plate or a nickel-plated iron plate to prepare the current collector. CONSTITUTION:A current collector is prepared by performing nickel plating on an iron plate and then performing tin plating on the nickel layer. Since the tin layer constituting the surface of the thus prepared current collector closely adheres to zinc used as the active material and also has high hydrogen overvoltage, it is possible to prevent the generation of hydrogen gas from the surface of the current collector. Even when a minute amount of tin is dissolved, there is no possibility that an oxidized film of nickel located under the tin layer is formed similarly to iron resulting in increased electric resistance. Accordingly, the current collector can be maintained in close contact with the negative active material over a long period, thereby obtaining awn alkaline storage battery with longer life.

IPC: B65D85/86
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To heat-weld by a sufficient bonding force regardless of the presence/ absence of a release treatment on a carrier tape, or the difference in material, etc., by forming an adhesive layer of a composition of which the major components are at least one kind of an ethylene-α olefin copolymer or an αolefin copolymer, and an ethylenevinyl acetate copolymer. SOLUTION: An adhesive layer 4 is formed of a composition of which the major components are at least one kind of an ethylene-α olefin copolymer or an α olefin copolymer, and an ethylene-vinyl acetate copolymer, and is formed by an affixing of films being formed in advance or an extrusion-coating. The adhesive layer 4 can avoid an unfavorable bonding due to an insufficient thickness, by the extrusion. Also, it is assumed that a required addition of a lubricant may unfavorably react to the adhesion, but the bonding force and the separation smoothness are improved by the mixing of the ethylene-α olefin copolymer or the α olefin copolymer, and the adhesive layer 4 is not affected by the material of a carrier tape made of a plastic or the presence/absence of a release treatment, and shows an excellent adhesion.

The material 11, the susceptor 2 and a nitrogen compd. decomposing jig 8 are heated by a heater such as an IR lamp 71. The NH3 ejected from a gas introducing port 41 is decomposed on the surface of the jig 8. The decomposed nitridable material diffuses easily in the formed Si3N4 film and arrives at the boundary between the Si3N4 film and silicon thus forming the Si3N4 film by reacting with the silicon. The growth of the hot silicon nitride film is thus easily progressed.

Title: Fail safe circuit in equilibrium transmission circuit
Inventor: YAMADA KAZUHIRO
IPC: H04L25/02
Filed: 1989-07-20
Abstract: PURPOSE:To perform signal transmission at high speed without impairing a fail safe function by applying a bias voltage on the input terminal of a receiver being always applied only when the disconnection of a transmission line due to the slip of a cable, etc., occurs. CONSTITUTION:The output of a transmission line disconnection detection circuit 1 is outputted as a signal corresponding to a normal state when an equilibrium transmission line is set at the normal state, and a switch circuit 2 connects two wires composing the equilibrium transmission line to the input terminals A and B of the receiver with the signal. A bias impression circuit 10 receives a normal state signal from the transmission line disconnection detecting part 1 when the disconnection of the transmission line occurs, and applies no bias voltage on the input terminals A and B of the receiver. Meanwhile, the transmission line disconnection detecting part 1 outputs an abnormal state signal when the disconnection of the transmission line occurs, and defines receiver output by applying a prescribed bias with the signal, and simultaneously, disconnects the two wires composing the transmission line from the input terminals A and B of the receiver. In such a manner, the receiver output can be defined when the disconnection of the transmission line occurs while eliminating the distortion of a transmission waveform due to the bias voltage.
