Title: Boring device and lock bolt construction method
Inventor: ITO HISAO
IPC: E21D20/00
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To reduce the work execution cost, simplify the structure and improve the workability by installing an opening and closing tip bit on the forward end of a casing. SOLUTION: When turning force and striking force are given to the base end of a casing 20, a hole 50 is bored by front chips 41d, 43b of a tip bit 40. At this time, a fixed rod member 30 inserted in the casing 20 is forced to track according to the drilling amount. After the hole 50 is drilled to a designated depth, the casing 20 is a little moved backward, and with the casing 20 held, the fixing rod member 30 is pushed into the inner side of the hole 50. Whereupon, a fixed member 31 of the point of the fixing rod member 30 forces a dividing cutter 43 to be opened outward centering round its pivot point. When the fixing rod member 30 is further pushed in, a band plate part 33 of the fixing member 31 is plastic-deformed to eat into the hole wall, and the tip of the fixing rod member 30 is fixed in the inner part of the hole 5-0.  Further, while consolidation material is discharged into the hole 50, the casing 20 is pulled out together with the tip bit 40 and only the fixing rod member 30 is left behing in the hole 50.

Title: Brake controller
Inventor: SEKO NOBUO
IPC: B60T8/00
Filed: 1998-10-05
Abstract: PROBLEM TO BE SOLVED: To provide a brake controller operable without receiving any power supply from outside. SOLUTION: At a time other than braking a vehicle, power generated in a speed generator 11 by the rotational motion of each wheel of the vehicle is supplied through the power source circuit 13 of a flow rectifying smoothing circuit 12 to a secondary battery 14. At the time of the braking of the vehicle, a sliding preventing device 16 detects the rotational speed of each vehicle from the frequency of an AC voltage generated in the speed generator 11. Thus, from the detected rotational speed of each wheel, the sliding state of the wheel is detected, and a braking force applied on the sliding wheel is reduced.

Title: Compact electric vehicle
Inventor: INUI TSUTOMU
IPC: A61G5/04
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To effectively prevent an on-vehicle battery from being overcharged at the time of going downhill, by decelerating the traveling speed with a decelerating means if a detected battery voltage is judged to exceed a first given value. SOLUTION: If a battery voltage is judged to exceed a given value, an electric motor 28 is used as a generator when traveling in deceleration on a downhill, for instance, and a battery 38 is charged while the traveling speed is decelerated with regenerative braking. But, charging voltage increases on a long downhill. If the battery voltage exceeds an overcharged voltage, therefore, duty ratio is made to decline gradually. Specifically, the duty ratio is made to decrease continuously by 1%, for example, so that the traveling speed decreases by about 2 km/h during the given period of time. This structure can effectively prevent an on-vehicle battery from being overcharged at the time of going downhill. The car does not have to be stopped. Simply needed is the decrease of the traveling speed.

Title: Hetero epitaxial growth method
Inventor: SUZUKI AKIRA
IPC: H01L21/20
Filed: 1986-11-27
Abstract: PURPOSE:To prevent a crystalline film from being warped and cracked by inclining the crystal face of a different kind of single crystalline film corresponding to the same face orientation as that of the growth face of a single crystalline substrate with respect to the growth face. CONSTITUTION:When a single crystalline grown film B of lattice constant (b) is epitaxially grown on a single crystalline substrate A of lattice constant (a), the crystal face orientation of the film B is inclined with respect to the substrate A thereby to reduce a distance between crystal lattices parallel to a boundary of the film B with respect to the lattice constant (a) of the substrate A smaller than the lattice constant (b) at a hetero junction boundary C to substantially largely reduce the degree of a lattice distortion. For example, when the Si single crystalline substrate surface is carbonized by a chemical vapor growth method to form a thin layer of SiC single crystal and an SiC single crystal film is epitaxially grown on the thin layer of SiC, the crystal face orientation 511 of the obtained grown film inclines 3.7 degrees with respect to the face orientation 511 of the substrate surface. Thus is can prevent the grown film from being warped and cracked.
