Abstract:
A system and method for automatically controlling a vehicle speed to a desired cruise speed are disclosed in which a vehicle speed sensor which output an analog quantity corresponding to a current vehicle speed is provided, a vehicle speed determining circuit which derives the current vehicle speed on the basis of the analog quantity derived from the vehicle speed sensor and determines whether the derived current vehicle speed is below a predetermined speed above which the cruise speed control run is appropriate is furthermore provided independently of a control unit of the system. When the vehicle speed determining circuit outputs a determination signal indicating that the current vehicle speed is below the predetermined speed and the control unit outputs a predetermined control command signal, a power supply line connected to a throttle valve actuator is, at first, interrupted. Then, the power supply to the control unit is interrupted.
Abstract:
A system and method for automatically controlling a vehicle speed to a desired cruise speed are disclosed in which whether a microcomputer of a control unit is enabled to perform a cruise speed control is determined on the basis of a plurality of determining factors and a power supply of a throttle actuator for actuating an engine throttle valve so as to adjust an opening angle of the throttle valve is enabled only when all of the determining factors satisfy a condition of enabling the cruise speed control via the actuator and is disabled when at least one of the determining factors does not satisfy the condition.

Abstract:
An automatic performance device is of a type in which the automatic performance is executed in accordance with musical data read out successively. It comprises a fast feed stop control circuit for advancing the progress of the automatic performance when an actual key depression timing is faster than an ideal key depression timing indicated by the read out musical data and for temporarily stopping the progress when the former delays behind the latter. Comparison between the actual key depression timing and the ideal key depression timing is made by comparing the content of a counter counting the tempo pulses which decides the tempo of the automatic performance with note-length information included in the musical data. It further comprises a tempo control circuit for changing a period of the tempo pulses based on a tempo of a performance made by the actual key depression. The detection of the tempo of the performance made by the actual key depression is based on a count value of a counter counting the clock pulses whose period varies with the note-length information and presence or absence of the actual key depression. In order to prevent the period of the tempo pulses from being changed by only one great deviation of the actual key depression timing, the count value is latched at every key depression, the newest count values are kept, and the tempo detection may be made in accordance with the average value of the newest count values.
Abstract:
An electronic musical instrument comprises a keyboard arranged to produce key code signals in response to key operations thereof and a memory storing performance data constituting progression of a music and corresponding to key operations to be effected on the keyboard to play the music. A key operation judging circuit is provided which compares the key code signals produced by the keyboard with the performance data read out of the memory to detect whether or not a pupil or trainee correctly operates keys in a corresponding relation to the performance data read out of the memory. The percentages of correct key operations are calculated and displayed with respect to the key-on timing and the pitch and duration of notes.

Abstract:
At the time of preparing polyphenylene ether resin, there can be separated and recovered efficiently an aromatic compound solvent, amines making an azeotrope with water (hereafter, referred to as ‘the amines’ for short.) and methanol. A method for producing polyphenylene ether, which comprises (a) a step for synthesizing polyphenylene ether by subjecting phenol to oxidative polymerization in the presence of a copper compound and amines in an aromatic compound solvent, (b) a step for precipitating polyphenylene ether particles by adding methanol into the solution of polyphenylene ether in the aromatic compound solvent obtained by the step (a), (c) a step for solid-liquid separating a slurry of polyphenylene ether obtained by the step (b), and then washing the separated polyphenylene ether particles with methanol to obtain the polyphenylene ether, (d) a step for adding water to a filtrate obtained by the step (c) to mix them, and then liquid-liquid separating the mixture into a phase consisting mainly of the aromatic compound and a phase consisting mainly of methanol and water, and (e) a step for supplying the phase consisting mainly of methanol and water, obtained at the step (d) to the middle portion of a distilled column to perform distillation, and separating out a distillate liquid consisting mainly of methanol, a bottom liquid consisting mainly of water and a side-cut liquid containing the amines by distillation, recycling the distillate liquid consisting mainly of methanol as methanol of the steps (b) and (c), and recycling the side-cut liquid as part of the filtrate of the step (d).

The dyed mixed fiber article containing polyurethane fiber can be prepared by dyeing a mixed fiber article composed of disperse dyeable fiber and polyurethane fiber, such as a co-knitted fabric, either in a dye bath in the presence of polyvalent metallic compound and tannic acid or after the co-knitted fabric has been treated in a bath containing polyvalent metallic compound and tannic acid.
Abstract:
A surface inspecting apparatus includes linear light sources 11, 13 for emitting illumination light toward a surface of a body panel 10 to be inspected, CCD cameras 12, 14 for imaging the surface and forming its illuminated images on the basis of reflection light from the surface, and an inspecting unit for detecting a defect existing on the surface on a basis of the illuminated image and outputting detected information about the defect. In the arrangement, the sources 11, 13 are arranged so as to obliquely emit the illumination light toward the surface at incident angles .alpha. from 80 to 90 degrees. While, the cameras 12, 14 are arranged so as to receive diffused reflection light of the illumination light reflected by the surface at reflection angles .beta. each smaller than the incident angle .alpha..
