Title: Controller for motor
Inventor: FUKUI YASUHITO
IPC: H02P29/00
Filed: 1989-08-04
Abstract: PURPOSE:To shorten a period of time until it arrives at a target speed by providing a motor speed error detector, a state detector for determining whether the amplitude of a period error signal falls within a range of a reference value or not to operate a differentiator, and a circuit for driving a motor in response to the output of an adder. CONSTITUTION:The rotating period of a motor 1 is converted to a signal proportional to the period by a rotation detector 2, and an error from a specified period is detected by a speed error detector 3. Whether the error signal falls within a predetermined range or not is monitored by a state detector 4 to drive an integrator 6 only if the response of the motor 1 is judged to be a normal state, and the error signal and the output of the integrator 6 are added by an adder 7. A driver 8 receives the output of the adder 7 to drive the motor 1. Thus, a period of time until it arrives at a target speed can be shortened.

IPC: H03F3/68
Filed: 1988-08-16
Abstract: PURPOSE:To prevent a damage of a normal amplifier by turning off a fault amplifier based on the output when a fault detection means monitors a power amplifier and detects the decreased output and reducing the output of a variable attenuator of other amplifier. CONSTITUTION:An input signal at an input terminal 11 is distributed by a distributer 12 and the result is synthesized by a synthesizer 15 via variable attenuators 13A-13C and power amplifiers 14A-14C and fed to the antenna. When the output of the amplifier 14 is lowered, a failure detection means 22 detects it, and the information is fed to a control circuit 23. The circuit 23 turns off a power switch 21A of the amplifier 14A to control attenuators 13B, 13C to other amplifiers 14B, 14C thereby reducing the output. Thus, the stress of a circulator in the normal power amplifier is reduced to prevent a damage thereby improving the safety and reliability of a transmission equipment.

Title: Optical waveguide switching element
Inventor: IRIE MASAHIRO
IPC: G02F1/19
Filed: 1991-07-19
Abstract: PURPOSE:To provide the optical waveguide switching element which controls the reflection or transmission intensity of light by photoirradiation at a high speed by constituting the switching element of a photochromic compd. thin film or high-molecular thin film dispersed with a photochromic compd. and a prism. CONSTITUTION:Incident light I0 enters the prism and is partly transmitted and guided at the boundary of the prism and the thin film. The remaining light is reflected. The guided light is captured by another prism. The intensity thereof is designated as I. The ratio of the intensity I of the guided light and the intensity of the reflected light depends on the incident angle of the light. The incident angle at which the waveguide intensity I is maximized is selected when the photochromic compd. is an isomer A. The refractive index of the thin film changes and the waveguide intensity I decreases if the photochromic compd. is irradiated with control light P1 and an isomer B is formed therein by a photochromic reaction. The optimum waveguide condition is again satisfied and the waveguide intensity I increases if the isomer B is returned to the isomer A by changing the wavelength of the control light to P2.

Title: Device and method for storing and for reproducing musical sound waveform data
Inventor: MATSUNAGA IKU
IPC: G10H7/02
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To accomplish a data compression by expressing the magnitudes of the points, which are located at the positions deviated by one wavelength among the points of musical sound waveform data, or the points of stereoscopic sounds on a coordinates as coordinate values, converting the coordinate values to the values on the coordinate axes, which are created by rotating the original coordinates by a prescribed angle, and storing the converted coordinate values. SOLUTION: A figure (A) indicates the coordinate points having the coordinate values of the levels of two points, which are deviated by one wavelength, or each stereoscopic sound. A figure (B) is created by rotating coordinate axes X1-X2 45 degrees. The values on rotated two dimensional orthogonal coordinate axes Y1-Y2 are obtained by computational conversions Y1=(1/SQR2)×(X1+X2) and Y2=(1/SQR 2)×(X1-X2) where X1 and X2 are the original values. The ranges of the coordinate values of the coordinate points on the rotated coordinate axes Y1-Y2 are slightly increased in the Y1 axis direction compared with the X1 axis direction. However, the ranges of the values in the Y2 axis direction are considerably reduced compared with the values in the X2 axis direction. Thus, as a whole, the amount of data of the coordinate values is reduced and the data compression is accomplished.

IPC: C23G1/00
Filed: 1983-10-31
Abstract: PURPOSE:To perform descaling in an excellent state, in removing oxide scale on the surface of a cold rolled Cr-type stainless steel strip after continuous annealing, by estimating the degree of difficulty of descaling from the reflective index of specific light and adjusting a descaling condition from the estimated data. CONSTITUTION:A cold rolled steel strip comprising Cr-type stainless steel such as SUS410 or SUS430 is continuously annealed in a oxidative atmosphere such as air. In removing scale generated to the surface of the steel strip by this annealing treatment, the oxide scale surface is irradiated with light having a wavelength of 600X10<-9>m or more and the reflective index thereof is measured. In this case, the relation of a reflective index and a descaling condition necessary for completing descaling is preliminarily calculated. From the actual reflective index, descaling conditions such as the concn. and temp. of a descaling solution, an immersing time, an electrolytic time or an electrolytic current density are properly controlled from the above mentioned relation to perform the enhancement in the surface quality (gloss) of the Cr-type stainless steel strip and the reduction in the amount of the descaling solution and the quantity of electricity.

Title: Formation of magnetic path for magnetic head
Inventor: SUENAGA TATSUTOSHI
IPC: G11B5/147
Filed: 1988-08-17
Abstract: PURPOSE:To lighten magnetic reluctance and to improve recording and reproducing efficiency by thickening the core thickness of all parts except an actuating gap part. CONSTITUTION:Magnetic alloys 2a and 2b to be a main magnetic path are partitioned into a main substrate 1a and an auxiliary substrate 1b, film-fitted, adhered with the pieces of glass 3a and 3b, and at that time, all the film fitting processing is executed by a sputtering method, etc. Further, when the magnetic reluctance in the actuating gap part is made into Rf, and the magnetic reluctance in the other parts is made into Rb, sensitivity S is expressed with an expression S=K(Rf/Rf+Rb) (K is a proportional constant). Thereupon, when the core widths of all the parts except the actuating gap part are widened, the value of Rb becomes smaller. Thus, sensitivity S becomes larger, and the recording and reproducing efficiency can be improved. Further, since the main magnetic path and an adhering glass are simultaneously film-formed by the sputtering method, etc., man-hour can be widely reduced.
