Title: Automobile body structure
Inventor: HASHIMOTO TAKASHI
IPC: B62D25/08
Filed: 2001-07-10
Abstract: PROBLEM TO BE SOLVED: To provide an automobile body structure causing little damage on an opening-closing panel by movement of a cargo loaded on a loading space. SOLUTION: A step part 20 restrains a direct collision with the opening- closing panel 6 of the cargo X loaded on the loading space 4. A reinforcing material 32 restrains a curve of the opening-closing panel 6 due to the moment around a colliding position of the opening-closing panel 6 caused by the collision. A support means 34 elastically regulates forward movement of a prescribed part of a rotary shaft 12 caused by the collision. Thus, this automobile body structure can restrain damage of the opening-closing panel 6 by using the step part 20, the reinforcing material 32 or the support means 34.

Title: Field-effect transistor
Inventor: MIYAKOSHI NOBUKI
IPC: H01L27/088
Filed: 2001-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a field-effect transistor which has a high-breakdown voltage and low electrical resistance. SOLUTION: A ring-shaped channel region 40 is formed inside a source region 39 formed like a ring, and the inside of the ring-shaped channel region 40 is used as a drain region. Since a depletion layer spreads toward the inside of the drain region, the breakdown voltage is high. The high breakdown voltage is obtained by placing a low-resistance conductive layer 26 on a position other than a prescribed distance from corners of the channel region 40. The ring- shaped channel region 40 positioned between branches of the drain region is formed like a semicircle, and the edge part of the inner circumference of an ohmic region 33 thereon is extended to the drain region rather than the other part, thereby improving the breakdown resistance amount.

Title: Voltage regulator and semiconductor integrated circuit
Inventor: TAKABAYASHI YASUTAKA
IPC: G05F3/26
Filed: 2001-07-30
Abstract: PROBLEM TO BE SOLVED: To provide a voltage regulator in which an increase in power consumption is small and an operation analysis of a load circuit is difficult. SOLUTION: When a load current caused to flow to a load circuit connected to an output node NO surpasses the supply capability of a constant current circuit 40, an insufficient load current is supplied from a PMOS 31 connected parallelly to the constant current circuit 40. On the other hand, when the load current caused to flow to the load circuit is not higher than a supply current of the constant current circuit 40, surplus current is caused to flow to a ground potential GND through an NMOS 32. The fluctuations of current supplied from a power supply voltage VDD can be suppressed with a small increase of power consumption by setting the supply capability of the constant current circuit 40 to an appropriate value that is equal to or less than a maximum load current. This manner can make an operation analysis of the load circuit by a monitor of a current signal waveform difficult.
