Abstract: PURPOSE:To enable the collection and delivery of a large quantity of goods on a small ground by dividing the floor of each story of a building having many stories into two, shifting the height of the divided floors by half a story from each other, partly overlapping said floors, and providing a vehicle road between each story. CONSTITUTION:In a building 1 having many stories (three stories in the case of figure), the each floor of stories 2F, 3F except the first story 1F is divided into two and the heights of the divided floors are shifted by the amount of half a story forming a middle third story 3MF and a middle fourth story 4MF. The 3MF and 4MF are partly overlapped with the 2F and 3F respectively providing the sorting areas of goods. Also, vehicle roads 14-17 with gentle slopes are formed among the 1F, 2F, 3MF, 3F, and 4MF to permit trucks to travel. When a roof floor RF is to be used as a parking area, a vehicle road is provided between the RF and 4MF. Each of the vehicle roads 14-17 are determined one-way traffic, separately providing up-slope roads from down-slope roads (figure omitted). Thereby, it is possible to carry out the collection and delivery of a large quantity of goods in small ground.

Title: Vacuum film forming device
Inventor: TSUINO YASUHIRO
IPC: C23C14/50
Filed: 1994-07-22
Abstract: PURPOSE:To suppress generation of worn powder from a device and to form films having high purity at a high yield by allowing planetary motion to be executed by a specific mechanism at the time of subjecting wafers to be treated in a film forming device to a film forming treatment while these wafers are made to make the planetary motion. CONSTITUTION:A material to be evaporated from an evaporating source 14 is deposited by evaporation on the surfaces of the plural semiconductor wafers W, by which uniformly vapor deposited films are formed on these surfaces in a vacuum chamber 12, In such a case, a substrate holder 11 mounted at the wafers W are made to make the planetary motion within the vacuum chamber 12, by which the uniformly vapor deposited films are formed on all of the plural wafers W. Since the planetary motion of the substrate holder 11 is executed by meshing of a first angular bevel gear 1 and a second angular bevel gear 2 in this case, generation of the worn powder like at the time of sliding friction resistance does not arise and the slightly generated worn powder is received by a covering plate 4 mounted at a lower side without splashing into the vacuum chamber and, therefore, the high-purity vapor deposited films extremely little in adhesion of the worn powder are formed on the surfaces of the wafers W.

IPC: B05C5/02
Filed: 1989-07-03
Abstract: PURPOSE:To make a coating film forming gap constant by arranging a die in a freely movable manner so as to allow the same to separate from and come into contact with a backup roll and providing a means pressing the die to a backing roll. CONSTITUTION:When a coating solution H is quantitatively extruded to a base material A from a coating solution extrusion slit 3, the coating solution H present in a shearing space S presses the lip surface 4 of a die 12 by constant pressing force P1. The die 12 is pressed to a backing roll 1 by the pressing force P2 of a press means 15. The dimension W3 of the coating film forming gap E formed between the outlet edge part 4a of the lip surface 4 and the surface Aa of the base material A becomes constant. The die 12 moves so as to follow the variation of the surface Aa of the base material A. As a result, the dimension W3 of the gap E is held to a constant value and a coating film with a thickness W4 is formed. By this method, the operating efficiency of equipment can be enhanced.

Title: Turning control device for vehicle
Inventor: SANO YOSHIAKI
IPC: B60T8/58
Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To sufficiently ensure the whole braking force without causing a shortage of braking force just after the start of braking by providing a regulating means for regulating the reduction of braking force of a wheel to be controlled in yawing control for a prescribed time after the start of linear braking. SOLUTION: According to this turning control device for vehicle, the reduction of braking force of a wheel to be braked in yawing control is regulated only for a prescribed time after the start of linear braking of a vehicle in the linear advancing state judged on the basis of the absolute value of estimated transverse acceleration of vehicle determined from a vehicle body speed Vb and a target yaw rate rt where its yawing control is not needed. Thus, even when the vehicle advances into a split road surface, the yawing control never substantially works. Consequently, the braking force of the whole vehicle is never deficient just after the start of linear braking of the vehicle, and the whole braking force can be sufficiently ensured.
