Abstract: When Ti as a barrier metal layer is brought into contact with a diffusion region of boron provided on a surface of a silicon substrate, there is a problem that boron is absorbed by titanium silicide, and contact resistance is increased. Although there is a method of additionally implanting boron whose amount is equal to the amount of boron absorbed by titanium silicide, there has been a problem that when boron is additionally implanted into, for example, a source region in a p-channel type, the additionally added boron is diffused deeply at the diffusion step, and characteristics are deteriorated. According to the invention, after formation of an element region, boron is additionally implanted into the whole surface at a dosage of about 10% of an element region, and is activated in the vicinity of a surface of a silicon substrate by an alloying process of a barrier metal layer.

Abstract: Purpose: To provide a laundry system with improved customer services by utilizing portable information terminals having a radiocommunication function such as mobile phones and PHS. Constitution: Upon completion of washing or drying in a laundry machine 102, data for notifying the user of the completion of the treatment are transmitted to the user's mobile phone 100. In addition, when a prescribed time, for example, 10 minutes, elapses after washing or drying finished, a request for permission to unload the laundry is transmitted to the user's mobile phone 100 so as to ask the user whether the clothes can be taken out from the laundry machine 102 or not. The system charges the user when a prohibition response is sent back or there is no response to the request for permission to unload the laundry.

Abstract: A car phone can be run from the battery of a vehicle in which it is mounted or from its own battery. If the vehicle ignition switch is turned off during communication, interrupting the supply of electric power from the vehicle battery, communication can continue because the internal power supply is automatically switched in.

Abstract: In the present invention, winding units (19) as a stator (23) are fixedly mounted in a cylindrical housing (1). A rotor (29) is provided on vanes (26) for supplying wind. The rotor (29) is disposed to surround the stator (23), thereby forming a brushless motor (30) that provides a hair direr having low noise level and lighter construction. The rotor has a sufficiently larger dimension in a direction of flow of wind than the stator (23). The stator (23) and rotor (28) are positioned relative to each other such that the center of the stator (23) in the direction of flow of wind is at the same position as the center of the rotor (29) in the direction of flow of wind. Thus, even if the rotor (29) moves slightly in the direction of flow of wind when the rotor (29) is rotating, the torque will not change significantly.
