Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To obtain an evaluated value capable of appropriately evaluating the roll of a car body by considering the transient components of the roll of a car body. SOLUTION: In the case that a car speed V is less than a reference value Vc and that the magnitude of the lateral angle θ of inclination of a road surface is less than a reference value θc (S50-S70), a roll evaluated value RV is computed on the basis of the yaw rate γ of a vehicle in which a phase is faster than the lateral acceleration Gy of a car body and a front wheel lateral force Ff (S80 and S90).  In addition, in the case that a car speed V is equal to the reference value Vc or more (S50) and that the magnitude of the lateral angle θof inclination of the road surface is equal to the reference value θc or more (S70), a roll evaluated value RVg is computed on the basis of the lateral acceleration Gy of the car body (S100), a roll evaluated value RVf is computed on the basis of the front wheel lateral force Ff (S110), and a roll evaluated value RV is computed as the average value of RVg and RVf (S120).

Abstract: PURPOSE:To prevent adjacent gold-plated interconnections from coming into contact with each other when a plated part is grown by a method wherein, while a polyimide resin film whose cross section is an inverted taper shape is used as a mask, a plating operation is executed. CONSTITUTION:A silicon oxide film 2 is formed on a semiconductor substrate 1, a titanium film 3a for close contact use and a gold film 3b for plating substratum use are deposited on it to form a photoresist 4, and a polyimide film 5 is coated and then etched back to expose the top of the photoresist 4.

Title: Marine reduction reversing gear
Inventor: KUBO MASAYUKI
IPC: F16H3/14
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To contract the diameter of a support shaft and compact the support shaft, by arranging on a second support shaft, an input driven gear engaged with an input gear on an input shaft, and transmitting power from a clutch gear on the second support shaft to a first support shaft. SOLUTION: An input driven gear 3 is attached on a second support shaft B. Therefore, power is transmitted to a first supporting shaft A from an input shaft 1 through the second supporting shaft B, and the total height of a case A is lowered. Regarding the second support shaft B placed especially under hard conditions, a deflection rate due to a load applied to the second support shaft B is diminished since the load position of the second support shaft B is positioned near to a bearing 16b however, the deflection rate in the conventional part is increased since the load position is separated from the bearing 16b. Therefore, the total height of the case A is suppressed so as to form the case A in a compact size, and especially, the diameter of the second support shaft B can be contracted.

Title: Sample cell for light-diffraction and scattering type particle-size-distribution measuring apparatus
Inventor: TOKAWA YOSHIAKI
IPC: G01N15/00
Filed: 1990-03-19
Abstract: PURPOSE:To make it possible to measure the distribution of the particle sizes from the particles having the small diameters to the particles having the large diameters over a broad range by chamfering a part of the outer surface of a sample cell. CONSTITUTION:A chamfered part 10 is formed at one edge part of an outer surface 2b of a sample cell 2 at the light emitting side. The angle formed between scattering light 5' and the chamfered part 10 is substantially expanded. The scattering light 5' is taken out of the sample cell 2 and detected with a detector 4'. Scattering light is transmitted through the outer surface 2b of the sample cell which is not chamfered and has the small scattering angle. The scattering light 5 is detected with a detector 4 which is otherwise provided. Therefore, the angle formed with the outer surface of the cell can be made large, and the angle formed between the scattering light and the outer surface of the sample cell becomes small. The scattering light which cannot be transmitted through the sample cell up to now can be measured. In this way, the particle size distribution of the particles having the large diameters can be measured over a broad range.
