Title: Plural focal points x-ray tube
Inventor: IWASAKI KENJI
IPC: H01J35/28
Filed: 1983-02-18
Abstract: PURPOSE:To make variable the distance of a filament from the target by a method in which a magnetic supply device able to keep a rotor magnetically free-rotatable and free-movable in the axial direction is provided inside the rotor in order to control a state of magnetism for moving in the axial direction. CONSTITUTION:When a control signal is dispatched from a control device 27, a power source of an electromagnet power source 28 changes while a current inside the electromagnet coils 13 and 14 for axial control changes. Accordingly, when magnetism of the magnetic paths S1 and S2 changes, the rotor 6 moves axially while the distance of a filament from an anode disc 5 changes. Said changed position is detected by an axial position detector 22. When the signal of said detector 22 is computed by a control device 27 to find the prescribed position, the current of the electromagnet power source 28 changes while the rotor 23 moves axially to set the desired distance of the filament from the target 5.

IPC: H03M13/23
Filed: 1995-02-14
Abstract: PURPOSE:To simplify the constitution and to perform the calculation at a high speed when the likelihood is calculated for each of N lines of paths that can be produced in a single block by calculating the likelihood value in a state where the square term of the signal vector is previously subtracted from each operation expression. CONSTITUTION:A vector string holding part 11 holds the signal vectors equal to one block and inputted in continuous (n) symbol sections. A virtual information generating part 12 and a coding part 13 successively generate the corresponding virtual code vector strings for each of N lines of paths that can be produced in a single block. A likelihood calculation part 14 inputs the held signal vector strings and each virtual code vector string and calculates each likelihood of N lines of paths. A likelihood comparison part 16 and a likelihood holding part 15 decide a maximum likelihood path that has the minimum likelihood. An information holding part 17 acquires the uncoded information on the virtual vector string corresponding to the maximum likelihood path from the part 12 and outputs the information as the decoding result after N lines of paths are processed. The part 14 calculates each likelihood of N lines of paths in a state where the square term of the signal vector is previously subtracted from each operation expression.

Title: Magnetostrictive torque sensor
Inventor: SASAKI HAJIME
IPC: G01L3/10
Filed: 1990-02-05
Abstract: PURPOSE:To improve the sensitivity of the magnetostrictive torque sensor by applying an AC voltage to a coil which produces magnetic flux penetrating a magnetostrictive film formed on the outer periphery of a rotary shaft, and detecting the variation in the iron loss of the coil with the torque operating on the rotary shaft. CONSTITUTION:The rotary shaft 9 which has the magnetostrictive film 1 formed on the outer peripheral surface is wound with a coil 3 and the AC voltage of specific frequency is applied from an AC power source 4 to the coil 3. When the torque operates on the rotary shaft 9 and the coil 3 produces the AC mag netic flux penetrating the magnetostrictive film 1, the iron loss (mainly, hystere sis loss) of the magnetostrictive film varies with the torque. This iron loss variation is detected from the phase difference between the AC voltage applied to the core 3 and a current fed to the coil. A current detection part 5 which is connected in series with the coil 3 detects the current I of the coil 3 and a torque calculation part 6 detects the torque of the rotary shaft 9 from varia tion in the resistance component of the coil 3. Thus, the torque of the rotary shaft 9 is detected from the AC resistance of the coil 3, so the sensitivity of the magnetostrictive torque sensor can be improved.

Title: Safety glass
Inventor: SAITO MITSUMASA
IPC: B32B27/18
Filed: 1995-02-14
Abstract: PURPOSE: To obtain safety glass effectively shielding heat ray without dropping a visible light transmittance, producible without changing the conventional production process of safety glass, by laying a non-rigid resin layer containing a heat ray shielding metal oxide between a pair of glass plates. CONSTITUTION: In safety glass comprising a pair of glass plates and a non-rigid resin layer laid between a pair of glass plates, a heat ray shielding metal oxide is added to the non-rigid resin layer. SnO2 or In2 O3 having >=0.lμm particle diameter is especially suitable as the heat ray shielding metal. The reason why the particle diameter is 0.1μm is that the scattering and absorption of visible light are enlarged and transparency can not be obtained when the particle diameter exceed 0.1μm. It is known that the light scattering by particles is maximized when the particle diameter is a size of 1/2 wavelength and is proportional to the sixth power of particle diameter in the region smaller than it.

Filed: 1990-02-05
Abstract: PURPOSE:To manufacture plural kinds of dielectric resonators whose resonance frequencies are close to each other through the use of a same metallic mold by setting a prescribed resonance frequency by grinding of a cavity. CONSTITUTION:A cavity dielectric body 2 and a core dielectric body 1 are molded integrally, an opening of the cavity dielectric body 2 is ground and an electrode film 8 is formed to an outer surface. Moreover, electrode films 9, 10 are formed to the inner face of ceramic boards 6, 7 respectively and baked and bonded to the end face of the opening of the cavity dielectric body 2. The interval between the electrode films 9, 10 formed respectively to the ceramic boards 6, 7 is decided by changing the size A of the two openings of the cavity dielectric body 2 and the resonance frequency of the resonator is decided. Thus, when the resonance frequencies of resonators are close to each other, plural kinds of TM mode dielectric resonators with different resonance frequencies are manufactured by using a same metallic die.

Abstract: PURPOSE:To provide an unknown system identifying method/device using a band division adaptive filter which can reduce the operational value and the converging time by controlling dynamically the tap number of the adaptive filter of each sub-band.

Then a tap number control circuit 11 produces the control signal to control the tap number of each adaptive filter based on the evaluating result of the circuit 10. Thus each adaptive filter changes its own tap number in response to the supplied control signal.

Abstract: PURPOSE:To detect the position of the tip of a probe for measurement in a noncontact manner, and to prevent a wafer breaking section and the breaking of the tip of the probe for measurement by detecting a position, where the amount of light of a received laser beam projected from a laser light-emitting device to a light-receiving means is transferred, from the light-receiving data of the light-receiving means. CONSTITUTION:The nose sections of a measuring electrode group 12 are detected by a laser beam L projected between a light-projecting means 17 and a light-receiving means 18, and the light-projecting and receiving means 17, 18 are fixed at positions lowered in the direction of a stage 13 only by known amounts. Consequently, when the stage 13 on which a specimen 16 is placed is moved in the direction of the measuring electrode group 12 and reaches a location interrupting a laser beam L, a stage drive means 14 is stopped. Vertical positioning is enabled under the state in which the interval of a known amount is kept between the wiring electrode group of the specimen 16 and the measuring electrode group 12. Accordingly, the generation of a wafer breaking section and the breaking of the tip of a prove for measurement can be prevented.
