Title: Magnetic recording and reproducing apparatus
Inventor: SAKAZAKI YOSHIHISA
IPC: G11B5/09
Filed: 1994-11-11
Abstract: PURPOSE: To obtain a magnetic recording and reproducing apparatus by which pieces of data whose rate is different can be recorded without changing a signal band. CONSTITUTION: Input data is given to a data-rate detection circuit 3, and the data rate of data to be recorded is detected. A mode discrimination circuit 4 sets a mode which is based on the rate ratio of a detected data rate to a standard rate. A tape drive circuit 7 sets a tape running speed which is based on the rate ratio. An input memory 2 outputs recording data covering one trace portion of a head at a time interval which is based on the rate ratio. A switch 10 gives the recording data to the head at the recording timing of the head, and it sets a non-recording period during other periods. Thereby, a recording operation can be performed at a track width and a track pitch which are indetical to those in an ordinary recording mode, and the recording time which is based on the rate ratio is obtained.  In addition, since the number of revolutions of the rotary cylinder is not changed, a signal band is not changed.

Abstract: PURPOSE:To provide a method of manufacturing a solar cell, where a filler of EVA resin is sandwiched between a surface material and a rear material to form the solar cell of required form in one piece, and a re-cutting process can be dispensed with. CONSTITUTION:An EVA(ethylene-vinyl acetate) resin 3 is cut into the same dimensions with a surface material 1, and a rear material 2 is cut into dimensions corresponding to the EVA resin 3. The EVA resin 3 is made to overlap the surface material or the surface material to tentatively fix a part of the resin 3 to the surface material or the rear material. Thereafter, a solar eel 1 and the rear material or the surface material are set and thermocompressed into one piece. Therefore, the shrinkage of EVA resin is prevented from shrinking due to heating by the surface material or the rear material which hardly shrinks by heating, or EVA resin and the rear material are previously cut into dimensions coincident with those of the surface material, so that protrusions from the surface material are prevented from occurring. As a result, a re-cutting process can be dispensed with.
