Title: Crystal resonator
Inventor: OZAWA TAKEO
IPC: H03H9/13
Filed: 1989-04-17
Abstract: PURPOSE:To suppress the deviation of an oscillated frequency due to the progress of corrosion of solder of a conductor thin film electrode by exposing a stuff not solderable and having a less diffusion coefficient of the component of solder around a soldering part between a lead wire and the electrode. CONSTITUTION:A conductor thin film electrode 12 comprising a Cr layer 12a and an Au layer 12b is formed to upper and lower faces of a crystal chip 11 and a lead wire 13 is soldered to the end with solder 14 made of a Pb-Sn alloy. Moreover, the Au layer 12b is selectively removed only at a region D close to the part soldering the lead wire 13. Since the Cr layer 12a not causing solderability to the Pb-Sn solder in the region D is exposed, no diffusion of solder takes place. Thus, no solder corrosion takes place and the deviation in the oscillated frequency is suppressed.

Abstract: PROBLEM TO BE SOLVED: To provide a recording and reproducing device capable of delaying recording and reproducing by arbitrary time after the start of the recording and reproducing before the start of the synchronous control of an external apparatus with substantially no change of the statement form of a tempo map. SOLUTION: The tempo map is composed of a music number 41, a tempo 2, a meter 43 and a sustain measure number 44. A '-' symbol is added to the sustain measure number of the tempo map at the top of each music. This '-' symbol signifies that a blank period after the start of the recording and reproducing before the start of the external apparatus is inserted. The numerical value following the '-' symbol indicates the length (measure number) of this blank period. When the start button of the recording and reproducing is pushed, the progression processing is executed by the measure number at the top of the tempo map and, thereafter, a start signal is outputted.  The external apparatus is, therefore, started with the delay by, for example, one measure after the start of the recording and reproducing and the starting simultaneously with the start of the recording and reproducing of the recorder does not arise.
