Title: Hose and manufacture thereof
Inventor: NODA TATSUTO
IPC: B29D23/00
Filed: 1994-04-28
Abstract: PURPOSE:To prevent a recessed part from developing on the inner peripheral surface in a hose, having curved part, so as to contrive to improve the durability of the hose at use. CONSTITUTION:A hose 1 is used for connecting an engine with a supercharger and equipped with a tubular general part 4 and rigid parts 5 locating at both the ends of the hose. At the boundary portion between the rigid part 5 and the general part 4, a tapered part 6, the diameter of which becomes gradually smaller from the rigid part 5 toward the general part 4, is provided. At the manufacturing of the hose 1, after a hose precursory body made of unvulcanized rubber is obtained, the hose precursory body is inserted onto a mandrel so as to be formed into the predetermined shape. After that, the unvulcanized rubber is vulcanized so as to obtain the hose 1. Though the predetermined stress difference develops between the rigid part 5 and the general part 4 due to the difference between the sliding resistances of the rigid part and of the general part at the insertion of the hose precursory body onto the mandrel, the difference between the stresses is gradually damped due to the existence of the tapered part 6, resulting in checking the concentration of stress difference at the boundary portion.

Title: Automatic focusing camera
Inventor: MAEDA HIROSUKE
IPC: G02B7/32
Filed: 1990-04-06
Abstract: PURPOSE:To enable accurate focusing on a subject on a short-distance side with two set lens positions by providing an interrupting means which stops and holds an attraction piece at a halfway position of a stroke and an operation member which interposes the interrupting means between strokes. CONSTITUTION:The attraction piece 12 is provided so that it can be put in and out of the stroke freely and the camera is equipped with the interrupting means 15 which is interposed in the stroke while a solenoid 11 is energized to stops and holds the attraction piece 12 at the halfway position of the stroke. Further, the camera is equipped with the operation member 21 which interposes the interrupting means 15 between strokes. When the solenoid 11 is energized, the attraction piece 12 is stopped at the halfway position of stroke movement and held so that the piece is not attracted into the solenoid more. Thus, even when the solenoid 11 is used for a lens driving mechanism, three lens positions are settable, so an infinite-distance position is settable in addition to a short- distance side and a long-distance side set position. Consequently, even a subject at an infinite distance position can be photographed in an accurate in-focus state.

On the other hand, a deciding circuit 9 inputs a temperature setting signal, discriminates a constant temperature state, a temperature rise state and a temperature fall state, and controls an operation of a refrigerator 3 and a blower 5. Accordingly, as for the operating state of the refrigerator being a device, the operation is stopped during the temperature rise state, and the refrigerator is operated at the time of the constant temperature state and the temperature fall state, therefore, start and stop of the refrigerator are decided by only a state of the temperature setting signal.
