Abstract:
An automatic performing apparatus of an electronic musical instrument comprises a memory for storing musical note data representing progression of a music to be played and control data for controlling such a generation mode of music tones being generated as tone color and modulation effect. The generation mode of musical tone signals generated by a tone forming circuit in response to the musical note data read out of the memory is also automatically controlled by the control data read out of the memory.
Abstract:
An electronic musical instrument comprises a keyboard, tone signal forming circuit to produce musical tone signals corresponding to keys being depressed on the keyboard, a memory to store musical performance data representing pitches and durations of notes and durations of rests according to the progression of a musical performance, a keyboard indicator to visually indicate which keys are to be depressed on the keyboard in accordance with the performance data read out of the memory so that the pupil or trainee may effect a musical performance on the keyboard by following the key indications, and an automatic musical performance device to effect an automatic musical performance in synchronism with the musical performance to be effected on the keyboard. A control circuit for the memory is arranged such that the key indication for each note in the progression of music is effected in the period of the duration of the immediately preceding note or rest. In other word, when the trainee depresses each melody note, the indicator points the key for the succeeding note.
Abstract:
The invention provides a method for producing a peroxymonosulfuric acid solution with high stability, including the steps of mixing 35 mass % or more of hydrogen peroxide and 70 mass % or more of sulfuric acid to react them, cooling the reaction solution to 80° C. or lower within five minutes after initiation of the mixing step, and diluting the reaction solution with water four times or more as much as the reaction solution by mass.
Abstract:
Provided is a process for producing bleached pulp, including subjecting unbleached pulp, which is obtained by cooking a lignocellulose substance, to alkali-oxygen bleaching treatment and then subjecting the alkali-oxygen bleached pulp to chlorine-free bleaching treatment including chlorine dioxide treatment, wherein in at least one chlorine dioxide treatment stage in which the chlorine dioxide treatment is performed, monopersulfuric acid is used in combination. The amount of chlorine dioxide to be used is reduced and the colour reversion resistance of the bleached pulp is improved by this process.
Abstract:
According to the present invention, there is provided a blood pressure-lowering agent, a vascular flexibility-ameliorating agent and foods having these functions imparted thereto, which are comprising isohumulones or a hop extract and/or an isomerized hop extract as an active ingredient.
Abstract:
The present invention provides an effective oxygen generating materials, carbon dioxide absorbing materials, and transport system and transport method of live fishery products for use upon transporting live fishery products. An oxygen generating materials of the present invention is prepared by packaging solid peroxide and peroxide decomposition catalyst with a moisture-permeable material having a cup method moisture permeability (40° C., 90% RH) of more than 20 g/m2/24 hr and being impervious to water at normal pressure. Furthermore, a carbon dioxide absorbing materials are prepared by packaging alkaline earth metal hydroxide and/or oxide with a gas-permeable material having a Gurley method gas permeability (JIS P8117) of 0.1˜3000 sec./100 ml of gas and being impervious to water at normal pressure. Moreover, the transport system of live fishery products are a transport system wherein the oxygen generating materials and carbon dioxide absorbing materials pertaining to the present invention are sealed inside a transport bag.
Abstract:
A process for continuously and stably synthesizing a ketazine from hydrogen peroxide, ammonia and methyl ethyl ketone in the presence of a solution containing a catalyst. The process comprises removing sec-butyl alcohol by distillation from methyl ethyl ketone, which is reused by circulation. Also a process for preparing a hydrazine hydrate which comprises hydrolyzing the ketazine. By circulating unreacted ketone, accumulation of impurities in the circulated ketone can be prevented to obtain a high yield of the ketazine and the hydrazine hydrate, for a long period of time.
Abstract:
A preparation process of hydrazine hydrate is herein disclosed which comprises the step of hydrolyzing a ketazine in a distillation column to obtain hydrazine hydrate, a nonionic surface active agent having a polyoxyethylene group in its molecule and/or silicon dioxide being present in the distillation column. According to this process, in the hydrolytic distillation of the ketazine, flooding can be inhibited and thus a stable operation can be accomplished. As a result, hydrazine hydrate can economically advantageously be prepared.
Abstract:
A surface defect inspection apparatus a lighting unit shaped in an arched form laid across the path of movement of an object under inspection for illuminating its surface. A light diffusion sheet is located between the lighting unit and the path of movement of the object for forming a bright and dark light pattern on the surface of the object. A plurality of light sensors are arranged in an arched form laid across the path of movement of the object. Each of the light sensors produces an electrical signal in response to light of reflection from the surface of the object. The electrical signal is converted into an image including the bright and dark light pattern. This conversion is repeated to produce similar images in sequence for inspection of a defect which may exist on the surface of the object.
Abstract:
A chucking portion (10) is supported at the lower part of a dip head portion (2) to be vertically movable in a horizontal state through four shafts. Two diagonally positioned two shafts 11a, 11b are formed by ball screws, and the other two (11c, 11d) serve as guide shafts. The dip head portion (2) contains a motor (12) for synchronously driving the two ball screws, and the chucking portion (10) horizontally engages a holding plate (A) holding a number of chip type electronic components (B) to downwardly direct the same. A dipping vessel (7) having a bottom surface which is coated with a thin film of paste is horizontally arranged under the dip head portion (2). Thus, it is possible to maintain the holding plate in parallel with the paste, for applying electrodes to the chip type electronic components with high accuracy.
