Title: Preparation of silicon hydride
Inventor: ITOU MASAYOSHI
IPC: C01B33/04
Filed: 1983-12-28
Abstract: PURPOSE:To improve yields of process for prepg. silicon hydrides by allowing an alloy contg. Mg and Si to react with aq. soln. of an acid to produce useful silicon hydride compds. such as monosilane, disilane, etc. by carrying out the reaction at <=0 deg.C. CONSTITUTION:(A) An alloy contg. Mg and Si (e.g. Mg2Si of ca. 20-300 mesh) is allowed to react with (B) aq. soln. (ca. 1-50wt% concn.) of acid (e.g. HCl, H2SO4) at 0--90 deg.C (pref. -20--50 deg.C). Since the above-described reaction is an extremely intense exothermic reaction, the reaction temp. is maintained at a specified value by an efficient cooling method, and local overheating should be prevented by a powerful stirring.

Abstract: PROBLEM TO BE SOLVED: To enable solving problems of gate material which remains behind and the deterioration of an element characteristic by forming a pair of source/ drain regions being opposed through a gate electrode respectively, on the surface of each side surface of a semiconductor layer. SOLUTION: It becomes possible to prevent effectively a semiconductor layer 12 from being etched, if a protective insulating film 13 is provided on the whole top surface of the semiconductor layer 12, for example, even if long- time etching with an extent of not leaving a gate material behind to be a possible cause for an interwiring short-circuit in the lower part of the semiconductor layer 12 is performed, in an etching process at the forming of a gate electrode 4. Accordingly, the removal of the gate material in the lower part of the semiconductor layer is made possible, without etching the semiconductor layer 12 in the source/drain region.  Further, on this occasion exposure of the upper part corner sections of the semiconductor layer is reduced, so it becomes possible to prevent the deterioration of the gate withstand voltage and the element characteristics, such as a sub-threshold characteristic.

Abstract: PURPOSE:To pick up vibrations from a musical instrument in simple form and to make an octave decision and a pitch name decision without any error by incorporating a piezoelectric element in the case of the tuning device and setting the resonance frequency of the case to a frequency other than the lowest basic sound of the musical instrument. CONSTITUTION:The sound generated by the musical instrument is transmitted as vibrations (a) to an external input part 1 which has the piezoelectric element 1b in the tuning device case 1a having the specific resonance frequency, but its high frequency component is removed by the resonance characteristics of the tuning device case and only vibrations which are close to the basic wave component are applied to the piezoelectric element 6, which outputs an electric signal. A waveform shaping circuit 2 converts an electronic signal into a signal which can be processed by a pitch extraction arithmetic circuit 3. The pitch extraction arithmetic circuit detects the deviation from the reference sound, the pitch name, and the octave according to a reference signal outputted by a reference signal generating circuit 4 and the data on them are displayed by a driving circuit 5. Consequently, the octave detection is accurately performed.

Abstract: PURPOSE:To prevent the separation of sealing tape from base tape, by intentionally heat sealing the sealing tape to the base tape with one side of the former extending beyond the edge of the latter and severing the extended side of the sealing tape. CONSTITUTION:Base tape 1 is provided with a plurality of cavities 3 equally spaced lengthwise along one side thereof close to its center 2 and with a plurality of feed holes 5 equally spaced lengthwise along the other side 4 thereof. To produce taping electronic parts, the electronic parts 6 are inserted in the cavities 3 of the base tape 1. The sealing tape 7 is heat sealed to the base tape 1 by a heat sealing heater 8. Since the sealing tape 7 is wider than the actually sealed region of the base tape, one side 9 of the sealing tape 7 extends beyond the edge of the base tape 1. After heat sealing, the extended side 9 thereof is severed by a cutter. The sealing tape is intentionally extended beyond the edge of the base tape, thereby preventing the improper heat sealing due to the meandering of the two tapes and the sealing heater is also partially extended beyond the edge thereof, thereby preventing the tape separation due to the shift between the heater and the tape.
