Japanese Surgeon's Daily Life

Inverter

　　Electric cars (EVs) have no engine and consequently, they are considerably quiet even in motion. The passengers only hear the noise from the tires. This contributes to the enhancement of comfort. The air-conditioner can quietly work without engines though the EVs don't have engines originally.
　　I often eat meals in the car rather than visit restaurants. It's very comfortable as I don't mind people around and enjoy YouTube or other contents on the net. Experiencing the ownership of an EV, I find it convenient and suited to camping. If you use tents designed for use along with the car, you can utilize the air-conditioner even in the tent.
　　I'm budgeting for camping gears recently and bought an inverter for my car at first. By using it, I don't need to worry about the shortage of the battery of my note PC. I can even take a freshly brewed coffee in my car. However, it's not enough for electric appliances which require much electricity like hair dryers and hot plates. I'm also thinking of buying a portable power station for camping.

MY STETHOSCOPE'S BROKEN

　　My stethoscope abruptly stopped working. When I used it a few days ago, it worked. I've used it for more than 20 years and I didn't have any problem.
　　I didn't know about the detailed mechanical structure of stethoscopes, but I assumed that its chest- piece must be responsible. I was afraid to throw it away, so I asked its manufacturer for repair or replacement of the parts only. I didn't want to throw it away because I'd used for more than 20 years and I was attached to it.
　　The person on the other side of the line advised me to take it to pieces and clean inside its tubing. The most common problem is seemingly the occlusion of its tubing. He told me that an air duster is helpful. I followed his advice and the function of my stethoscope completely recovered.
　　Then, I wondered... What I blew out of the tubing was my earwax of 20 years? How did it smell or what was it like? The substance that was stuck in the tubing had already diffused in my room. I should have cleaned it outdoors.

TESLA SUPERCHARGER V3

　　I own a Tesla car, Model 3. As you know, it's an EV. I usually charge it at home at midnight. Its charging speed is slow, but the charge is done while I sleep and it finishes before I start next morning, so I don't mind its slowness. You would understand what I mean if you imagine the charging of your smartphone.
　　On the other hand, I utilize a public charging service while being away from home. Not only Tesla cars but every EV can be charged from this service and its speed is higher than that of the charger of my home. However, its speed is not ideally high.
　　Tesla, Inc. is building their exclusive charging facilities across the world. The third generation of the charger was set in the adjacent prefecture recently. You have only to put the plug in the car and your car is automatically identified and the bill is also automatically charged to your credit card. The charging speed is marvelous. The electricity for the 1100km drive can be charged in an hour as you see in the following picture.
　　Then, the Tesla-charger will be apparently launched in my home town. I'd not use it, as I have a charger in my home, but even people who don't live in detached houses would purchase Tesla cars. The number of Tesla cars from outside the city would increase I hope.
