Title: Curved belt conveyer
Inventor: MIZOUCHI SEIJI
IPC: B65G15/02
Filed: 1982-03-15
Abstract: PURPOSE:To prevent dislocation of a belt from a roller in a direction changing part, by allowing an optional point of a rod provided to the direction changing part of a curved belt conveyer to perform turning motion in the direction at a right angle with the direction of a belt width. CONSTITUTION:Rods 13 of a belt guide roller 3 in an inlet side and rods 13 of a belt guide roller 4 in an outlet side of a direction changing part 1 are contacted to the bottom surface of a belt 2 and moved by friction between the rod and the belt 2. Since rotary shafts 9, 10 of base plates 11, 12 supporting the rods 13 are placed in the same direction as the direction of a belt width further pin shafts 14 supporting the rod 13 are located also in a parallel position to the shafts 9, 10, the rods are guided by rotary motion of the plates 11, 12 and rotatively moved. That is, an optional point on the rod 13 performs turning motion in a vertical plane in the direction at a right angle with the width direction of the belt 2, in consequence, dislocation is never caused between the flat belt 2 and the  rod 13 and the belt 2 is not detached from the rod 13.

Title: Cooling system
Inventor: KUMAGAI TAKASHI
IPC: H01L23/36
Filed: 1988-02-24
Abstract: PURPOSE:To enable temperature rise in a heating unit of a following stage to be controlled within a specified value without the amount of air blasting being increased and a large fin being employed, by a structure wherein both a low fin density section and a high fin density section are provided in a set of fins which are installed to each the heating unit in the cooling passage, and the heating units adjacent to each other are disposed to be reversed with respect to the fin density. CONSTITUTION:With a preceding heat sink 11, the fin density of the upper half section 24 is high (i.e., dense) while the fin density of the lower half section 25 is low (i.e., non-dense). On the contrary, with a following heat sink 12, the fin density of the upper half section 29 is low (non-dense) while the fin density of the lower section 30 is high (dense). That is, the preceding heat sink 11 and the following heat sink 12 are disposed so that with the respective set of fins, the high fin density sections or the low fin density sections are not opposite to each other. When a cooling fluid is caused to flow in the direction indicated by an arrow, with the preceding heat sink 11, the high fin density section 24 has a large heat transfer area. Therefore, the high fin density section 24 thermally exchanges a large heating value with the cooling fluid, compared with that of the low fin density section 25, which results in increasing of temperature in the cooling fluid.
