Inventor: NAKAMURA TADASHI
IPC: B60K17/348
Filed: 1988-06-28
Abstract: PURPOSE:To improve an operating property by connecting a front-wheel speed change gear to a front-wheel steering mechanism by means of an artificial speed change operating tool and providing a switchover means for returning the front-wheel speed change gear to a connecting side at the time of returning to a low speed condition after temporarily traveling at a high speed while traveling at a low speed. CONSTITUTION:In a four-wheel-drive type agricultural tractor, the power of an engine is transmitted to rear wheels via a transmission case, etc., and the power branched off of a sub-speed change gear in the transmission case is transmitted to front wheels via a front-wheel speed change gear 9. The shift member of the front-wheel speed change gear 9 is connectable to the knuckle arm of a front-wheel steering mechanism while providing an artificial switchover operating tool 15 for carrying out the connection/disconnection thereof. In this case, the artificial switchover operating tool 15 is connected to an artificial speed change operating tool 21 for operating traveling speed change via a connecting rod 22, so as to switch over the front-wheel speed change gear 9 to a disconnecting side when the artificial speed change operating tool 21 is operated to a high speed side while returning the front-wheel speed change gear 9 to a connecting side at the time of returning same to a low speed side.

Title: High pressure discharge lamp
Inventor: ITAYA RYOHEI
IPC: H01J61/54
Filed: 1989-06-23
Abstract: PURPOSE:To control distribution form of a material adhered to the lower inner wall surface of a luminous tube after a lamp is switched off, and by decreasing the discharge starting voltage by contracting the spatial distance of the tube between an electrode and the metal material by arranging the luminous tube provided with a groove in the inner wall surface in a tube axial direction, in such a way that the groove is directed downward, which is horizontally burned. CONSTITUTION:A high pressure discharge lamp is horizontally burned with a groove 6 provided on a luminous tube 5 directed downward, and when it is switched off, due to the groove provided on the lower inner wall surface of the luminous tube 5, local heat capacity in this portion is smaller compared to other portions, and is rapidly cooled when the lamp is switched off. The temperature of this portion is decreased faster than the other portion of the luminous tube 5, and as a metal material 9 is adhered along the groove 6, the distribution of a metal material 9 adhered to the tube wall can be controlled. Also, as the metal material 9 is a conductor, by forming a discharge path by creeping discharge, and by discharging the short space between electrodes 7, 8 and the metal material 9, discharge starting voltage can be decreased, whereby starting and resuming time can be contracted.

Title: Load control method for material testing machine
Inventor: HIRAKI HITOSHI
IPC: G01N3/08
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To make a shock small when a test piece breaks. SOLUTION: While the displacement is small on a load displacement curve, the displacement is almost proportional to the load, but the load is not proportional to the displacement beyond the yielding point of a material. In the area (A) from the start of pulling to the switching point shown by α, low-speed load control is so performed that the elongation speed of the material is relatively slow. In the area (B) from the switching point α to a point β right before breakage, high-speed load control is performed. Once the point β right before the breakage is detected, the load is minimized to reduce the shock at the time of the breakage.

IPC: H01L21/306
Filed: 1983-09-07
Abstract: PURPOSE:To simplify a process of patterning, eliminating need of a resist, by selectively implanting atoms into a distributing or insulating layer and by patterning it utilizing the difference of etching rates between the implanted section and non-implanted section. CONSTITUTION:For patterning the thin film 202 for an electrode formed on a semiconductor substrate 201, atoms 203 are first implanted into the thin film 202 in a selective manner. The section 204 implanted with the atoms has a larger etching rate than the section 205 without atomic implantation. When the film is etched, the section without atomic implantation 205 also reduces its thickness by etching, while the section 204 implanted with atoms is etched more since it has a larger etching rate. Thus, the thin film 202 for an electrode can be patterned. The atomic species and the accelerating energy for implanting atoms are selected depending on the thickness and type of the thin film to be patterned so that the implanted atomic species do not enter into the semiconductor device.
