Title: Method and apparatus for controlling induction machine with built-in magnet
Inventor: SHIBATA YOSHIYUKI
IPC: H02P25/03
Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To provide a highly responsive method and apparatus for controlling an induction machine with built-in magnets. SOLUTION: Whether the difference between the actual speed value of an induction machine and its speed command value is not smaller than a threshold δor not, is judged (S12). In this case, when the difference is smaller than its threshold δ (S12 is No), i.e., when the change of its speed is zero or small, making the value of its magnetic flux quantity a constant value ϕ0, it is controlled by a vector controlling mode (S14). On the other hand, when the difference between its actual speed value and its speed command value is not smaller than the threshold δ (S12 is Yes), i.e., when the change of its speed is large, interrupting the control of making its magnetic flux quantity constant, its magnetic flux quantity (its magnetization current) is increased responding to the difference between its actual speed value and its speed command devalue (S16). As a result, the following quality of its cylindrical rotor equipped with permanent magnet after its rotating magnetic field is improved to increase its responsiveness.

Title: High temperature oxidation resisting surface treatment
Inventor: NAKAMORI MASAHARU
IPC: C23C10/46
Filed: 1995-02-01
Abstract: PURPOSE: To obtain a high temp. oxidation resisting surface by coating a material for high temp. service, selected from Fe-base alloy, Ni-base alloy, Co-base alloy, and carbon matrix composite, with Mo and applying Si penetration treatment. CONSTITUTION: For example, an Fe-base alloy A286, a Co-base alloy ECY768, an Ni-base alloy IN738Lc, and a carbon matrix composite are used as a base material 1, and this base material 1 is subjected to low pressure plasma thermal spraying with Mo (>99.99%) 2 so that about 100μm film thickness is obtained. Subsequently, silicon diffusion treatment is applied by embedding the above material to be treated in silicon powder containing 3% NH4Cl and holding it at 1100 deg.C for 2hr while allowing hydrogen gas to flow, by which a silicon penetration layer 3 of Mo-Si compound is formed. The Mo-Si compound forms an Sin, film on the surface at high temp. and produces excellent high temp. oxidation resistance, and microcracks and pores, as factors in causing the acceleration of the high temp. oxidation, can be removed by silicon penetration.  Because the layer 3 has a gradient structure in which Si/Mo is gradually increased toward the surface, it has excellent resistance to peeling.

Title: Exchange
Inventor: TAKAHASHI YASUSHI
IPC: H04L12/42
Filed: 1993-02-02
Abstract: PURPOSE:To prevent a cell from being abandoned at an input node in the large capacity exchange and to facilitate and accelerate exchange processing.

Title: Manufacture of semiconductor device
Inventor: ISHIBASHI MASARU
IPC: H01L29/73
Filed: 1988-01-28
Abstract: PURPOSE:To eliminate the need for allowing in advance for masking errors in a base contact hole forming process and to prevent short-circuiting between an emitter and base by narrowing the emitter.base distance by a method wherein a base contact hole is provided by self-alignment with an emitter contact hole. CONSTITUTION:With a silicon dioxide film 11 in an emitter.contact hole 15e being covered by a polycrystalline silicon film 16, there is no need for photoetching for the formation of a base contact hole 15b. This eliminates the need for allowing in advance for masking errors in a process of creating a gap between the emitter contact hole 15e and the base contact hole 15b, which renders this design quite suitable for miniaturization. With the polycrystalline silicon film 16 being formed on the side walls of the emitter contact hole 15e, there will be no emitter.base short-circuiting even when an emitter region 17 is composed simply of an intrinsic region. Accordingly, an emitter region 17 of this design may be small in stripe width.

Title: Production of thin film magnetic head
Inventor: MORIKAWA KAZUTOSHI
IPC: G11B5/31
Filed: 1988-01-27
Abstract: PURPOSE:To prevent swelling of an insulating layer and to obtain a head which is hardly deteriorated in magnetic characteristics by forming the insulating layer by heating and curing of an inorg. material coated by a sol-gel method. CONSTITUTION:The insulating layer 3 which insulates a conductor coil 4 from magnetic layers 1, 5 is formed of the inorg. material which is coated by the sol-gel method and is cured by a heat treatment. The flat layer of the inorg. material such as SiO2 of high purity is easily formed by heating at a relatively low temp. in the sol-gel method. The inorg. material is generally less likely to be swollen by humidity than org. materials and decreases the volumetric change of the insulating layer 3 by a temp. change. The head gap part is, therefore, less cracked and the insulating layer 3 is prevented from swelling even if said layer is exposed to high humidity. The magnetic head which is hardly deteriorated in the characteristic is thus obtd.
