I have saved data on hard disc of my computer or on MO as a general rule. I tried to find copies of lost mails from my letter files but only little of them was available. I presumed that I should try to restore some of important mails with help from related personals. But first I asked Mr. Nakamura to study whether it was possible to restore the ones.
Meanwhile my audio equipments sounded brokenly again. I presumed that a coaxial cable was responsible for such troubles. The digital signals from sound resources are transferred through optical cables to the converter excluding a coaxial cable which connects Sony's DAT(Digital Audio Tape Deck) to Sony's DAS-R1 (Converter Unit). I think this is a wrong design by Sony. The coaxial cable is not durable enough for a long use. The plugs of cable ends are rusted and become imperfect-connection. The product is high priced. But I decided to buy a 1.50 meter cable at the cost of 17,000 yen in Akihabara. The result was so good that the sound came out perfectly.
I delayed about one hour to arrive at Kawaguchiko from the appointment time to Mr. Nakamura. I made a big mistake. I have forgotten to put my note PC in car trunk. He gave me advises on the new Vaio which he recommended to me. I came back without having any result today.
