Abstract:
The present invention relates to a method and a system for recycling wash residue of ready mixed concrete include the steps of condensing used cement sludge to a predetermined concentration, storing the condensed sludge, sampling the stored sludge and determining the unhydration ratio of cement contained in the sludge, and weighing the stored sludge based on the determined unhydration ratio of cement in order to prepare a new batch of ready mixed concrete or mortar. By determining the unhydration ratio of cement contained in the sludge which has been condensed to a predetermined concentration, it becomes possible to accurately know the ratio of cement contributing as cement and its ratio contributing as the aggregate in a new batch of ready mixed concrete. A new batch of ready mixed concrete can be prepared by weighing the amount of the sludge on the basis of the determined unhydration ratio. The ready mixed concrete thus prepared will have a desired hardening strength and drying shrinkage.
Abstract:
An electronic musical instrument is provided with tone color specifying switch, musical style specifying switch and device for deciding the joint of melody tones based on the tone color and musical style specified by these switches. A new-timing melody tone is decided to be jointed with a preceding timing melody tone, based on the specified tone color and musical style, in the state of melody tone joint, for example legato state or nonlegato state, during the preceding timing melody tone is being generated.
Abstract:
A fluorescence correlation spectroscopy analyzer 1 is equipped with an excitation light illuminating optical system 21, a fluorescence imaging optical system 22, a CCD camera 15, and a data analyzer 16. The excitation light illuminating optical system 21 illuminates excitation light onto a predetermined region of a measured sample S. The fluorescence imaging optical system 22 images the fluorescence generated at the measured sample S onto the photodetection surface of the CCD camera 15. The CCD camera 15 performs photoelectric conversion of the fluorescence made incident onto the photodetection surface in accordance with the respective pixels and outputs the charges generated by the photoelectric conversion as detection signals from an output terminal. The data analyzer 16 inputs the detection signals based on the charges generated at the pixels, among the pixels of the CCD camera 15, that belong to an analyzed pixel set and computes autocorrelation functions of the input detection signals according to each pixel. A fluorescence correlation spectroscopy analyzer, which is enabled to perform fluorescence correlation spectroscopy analysis on multiple points of a measured sample simultaneously and at high speed, is thus provided.
Abstract:
The invention relates to a fluorescence measuring apparatus to which a CCD camera capable of measuring fluorescent components emitted from a specimen corresponding to excitation pulse components emitted at regular intervals toward the specimen is applied. The fluorescence measuring apparatus has at least a CCD and a controller. The CCD includes photoelectric converters for implementing photoelectric conversion of the fluorescent components emitted from the specimen, and charge storage elements for storing and transferring charges resulting from the photoelectric conversion by the photoelectric converters. The controller outputs an electronic shutter signal for sweeping away the charge resulting from the photoelectric conversion by each photoelectric converter, a readout signal for reading the charge resulting from the photoelectric conversion, to the charge storage element, and a transfer signal for sequentially transferring the charge thus read. In particular, the controller outputs the electronic shutter signal corresponding to generation of each excitation pulse component, outputs the readout signal corresponding to output of the electronic shutter signal, and outputs the transfer signal per predetermined number of readout signals outputted.
Abstract:
An electronic musical instrument provides a keyboard providing plural keys, memories for storing necessary programs and data, a musical tone signal generating circuit providing plural channels and a control unit such as a micro computer. A melody tone is designated by depressing a melody key within the keyboard. Then, an additional tone is automatically generated in relation to the melody tone by executing the programs, wherein its pitch, volume and tone color are controlled by the control unit. The melody tone and additional tone are assigned to desirable channels, from which the melody tone and additional tone are generated at different phonic positions. By varying the number of forming pattern of additional tones, it is possible to carry out the performance full of variety. Preferably, the additional tone is selected identical to a chord constituent note within a chord designated by performing the keyboard.
