Abstract: PURPOSE:To accelerate a control system by providing a multiple quantum well (MQW) optical waveguide layer formed on a semiconductor substrate, a diffraction grating formed along the optical waveguide layer, and an electrode which impresses an electric field on the optical layer perpendicularly. CONSTITUTION:When a reverse bias voltage is impressed from a terminal 1, the voltage is added on the MQW optical waveguide layer 8, and the average refractive index and the absorption coefficient of the optical waveguide layer 8 are changed by a quantum confinement Stark effect. When a control pulse voltage is impressed from a terminal 2, it is superposed on the reverse bias voltage, and accordingly, the average refractive index and the absorption coefficient of the optical waveguide 8 are changed. In a state where no control pulse voltage is impressed in case of setting the reverse bias voltage and the control pulse voltage, a waveguide mode as shown in A is set, and by impressing the control pulse voltage, the average refractive index and the absorption coefficient of the optical waveguide layer 8 can be increased by the quantum confinement Stark effect, and the equivalent refractive index of whole of the optical waveguide layer is increased, thereby, the reflecting area of a narrow-band filter consisting of the diffraction grating 6 and the optical waveguide layer 8 is moved to a long wavelength side as shown in B, then, a mode goes to a reflection mode, and incident light is cut off.

Title: Method of testing brushless synchronous machine
Inventor: TSUDA HIDEAKI
IPC: H02K19/00
Filed: 1993-09-13
Abstract: PURPOSE:To determine a synchronous reactance and a short-circuiting ratio of a synchronous machine precis without the use of a slip ring by holding a field current of an exciter to perform a test of a temperature rise. CONSTITUTION:A brushless synchronous machine keeps the temperature of a cooling gas on the low temperature side in a machine constant at a rated speed and initially, a terminal of an armature is opened to adjust a field current Ife of an exciter so that a rated armature voltage Van is generated. A temperature rise testing is performed until the field current reaches a fixed value to determine a value Ifeo of the field current thus fixed of the exciter. Then, the terminal of the armature is short-circuited in three phases and with the field current Ifeo of the exciter held intact, a temperature rise testing is performed until the armature current reaches a fixed value to determine the armature current Iao reaching the fixed value. The short-circuiting ratio SCR of the synchronizer is calculated by an expression of SCR=Iao/Ian from the current Iao and the current Ian. In addition, the synchronous reactance can be determined easily as it is an inverse of the short-circuiting ratio SCR.

Filed: 1988-09-13
Abstract: PURPOSE:To effect adsorption at a constant speed by locating an inlet for the liquid to be treated at the lower extremity of a tank and spewing the liquid against the particles moving upward through its narrow opening. CONSTITUTION:The liquid to be treated is introduced through a liquid inlet 1, mixed with particles from a particle entrance opening 7 at the lower part of a downward flow part 4 and moved, together with the particles, up to an upward flow part 3.

Title: Data recording medium and data recording/reproducing apparatus
Inventor: SEO YUZO
IPC: G11B5/596
Filed: 1993-08-20
Abstract: PURPOSE:To simplify a tracking control mechanism of a data recording/ reproducing apparatus. CONSTITUTION:A magnetic signal including two signal components of different wavelengths is recorded as a servo signal for a data recording medium into a servo track of a servo recording area 5 set corresponding to a data track of a data recording area 4. Signal components of the servo signal are so recorded as to show phase differences which are different one after another for every track. Each signal component has a longer wavelength than a recording wavelength of a data. The servo signal is recorded in a deep part of a magnetic layer 2 and, the magnetic data is recorded on a surface part of the magnetic layer 2. The magnetic data and servo signal are read at a common magnetic gap. Since an optical servo signal is not used, a simplified tracking control apparatus can be used. The apparatus is particularly applicable to a floppy disc apparatus.

Title: Eddy current type strong ac magnetic field generator
Inventor: BESSHO KAZUO
IPC: H01F7/20
Filed: 1986-09-29
Abstract: PURPOSE:To continuously generate an AC magnetic field statically with a device of simple construction by converging the AC magnetic field in an air gap provided to conductors and converging a magnetic flux in a fine hole formed in the conductor by increasing a magnetic flux density. CONSTITUTION:A fine hole H is formed at the center of a conductive plate 8 of a single structure, and a slit S which arrives at the outer edge from the hole H is provided to suppress the increase in the thermal loss due to an eddy current. A conductor pair of such a structure is so inserted to be held in a gap of air core coil pairs 5a, 5b that the position of the hole H coincides with a coil axis. When an AC voltage is applied to the coil pairs 5a, 5b in such a structure, an AC eddy current is generated in a plate 8 to form an opposite magnetic field, the AC magnetic field of the coil pairs 5a, 5b is partly cancelled by the opposite magnetic field to disturb the passage of the AC magnetic field through the plate. A uniform magnetic flux distribution due to the pairs 5a, 5b is effectively converged mainly in the hole H. As a result, the AC magnetic field can be easily generated continuously by a magnetic flux shielding effect based on time generation of the eddy current.

Title: Electric discharge machining device for nonconductive material

IPC: B23H1/00
Filed: 1993-09-14
Abstract: PURPOSE:To stably perform minute machining by providing a drive means driving a tool electrode while a relative position between the tool electrode and a non-conductive material is being controlled in response to the light intensity of a light detection means. CONSTITUTION:Specified voltage is applied to between a tool electrode 3 and a counter electrode 4, so that electric discharge is thereby induced at the tip end of the tool electrode 3. At this time, an average value every about 2ms of an intensity of discharge plasma light is outputted roughly 100 times by a light detection means 7. A value which is roughly 10 times as large as the maximum value out of the aforesaid average value, is set in a personal computer 8b as a threshold current value. Processing is then carried out while the average value every about 2ms of an intensity of discharge plasma light is being measured. At this time, an average light electric current is compared with the threshold value, and if the threshold value is found to have been larger, a drive member 8a is driven, so that the tool electrode 3 is thereby moved to the side of an alumina 2 roughly by 1mum.
