由我校应用物理研究所与电子厂联合研制的WXP—JSI型五线谱投影示教仪,在国家教委教学仪器研究所的认可并委托省教委教学仪器供应处主持下,已于1986年10月16日通过了技术鉴定。“音乐示教仪”是国家教委教学仪器设备研究所,1985月6月下达给我校电子厂的研制项目。经该厂同志们的努力,1985年10月中旬完成了样机的试制,后经湖北省音乐学院等单位试用,效果良好。其技术指标已达到:1)投影面尺寸:250×250(mm);2)音域:bA—G(24音);3)电路构成,集成块15块,晶体管50支;4)输出功率:最大10W;5)电源供电:AC220±10%,50
By the Institute of Applied Physics and Electronics Factory joint development of the WXP-JSI-type ward projection instrument, the State Board of Education Teaching Instrument Institute approved and commissioned by the provincial Education Commission under the auspices of the instrumentation supply, in October 1986 16 Japan passed the technical appraisal. “Music Teaching Instrument” is the State Education Commission teaching equipment Institute, issued in June 1985 to my school electronics factory research and development projects. After the efforts of the comrades in the factory, prototype prototype was completed in mid-October 1985, and after the trial by Hubei Conservatory of Music and other units, the effect was good. The technical indicators have reached: 1) Projection surface size: 250 × 250 (mm); 2) Range: bA-G (24 tones); 3) Circuit structure, integrated block 15, transistor 50; 4) Output power: Maximum 10W; 5) Power supply: AC220 ± 10%, 50
