Title: Thermal medium circulating type heating furnace
Inventor: SHINOZAKI SHIGEO
IPC: F28D7/14
Filed: 1993-09-28
Abstract: PURPOSE:To eliminate a heat exchanger for use in heat exchanging between thermal medium and process fluid by a method wherein a heating pipe of a direct firing type heating furnace is of a double pipe, thermal medium supplied from a circulating device is passed to an outer pipe so as to heat fluid (process fluid) of low temperature flowing inside an inner pipe. CONSTITUTION:A heating pipe 2 of double pipe type is vertically supported on the same circumference along a furnace wall inside a main body of a vertical cylindrical heating furnace, a burner 4 is arranged at a central part of a furnace floor directed upward and then the heating pipe 2 is heated with combustion heat when fuel such as city gas or the like is ignited with the burner 4. Thermal medium in a service tank is supplied to an inlet nozzle 8 of the heating pipe 2 facing against the outer pipe, heated during a stage while the fluid is flowing at the outer pipe, thereafter the thermal medium is returned to the service tank and circulated there. In turn, the process fluid acting as the heated fluid is supplied to an inlet nozzle 11 at the inner pipe and heated with convection heat transfer of the thermal medium of high temperature flowing at the outer pipe when the fluid flows in the inner pipe and after this operation, the fluid comes out of the outlet nozzle 12 of the inner pipe, returns to the process device and is circulated there.

Title: One-way motive power transmitting device
Inventor: ARAKI TOSHIICHI
IPC: F16H48/38
Filed: 1993-09-13
Abstract: PURPOSE:To facilitate starting an automobile more easily by providing a connecting point capable of freely being rotatable for the outer end section of a faced gear different in radius, changing over a meshing condition with a large gear, and thereby interrupting motive power transmission to the reverse direction. CONSTITUTION:When a gear 5 linked with a driven shaft B is out of operation, a gear 3 is also is out of operation via a gear 4 meshed with the gear 5 by a hold plate E. In this case, when a gear 1 linked with a drive shaft A is normally rotated, the position of the connecting point C of a gear 2 to be meshed by a hold plate D and the gear 3 of the hold plate E is moved from a starting point 1c to a position 3c by means of the autorotation and the revolution of the gear 3 and the revolution of the suspended gear 3. Since the gear 2 is different in radius from the gear 3, the provision of the connecting point C permits no reverse rotation beyond the meshing point of the gear 3 with the gear 4. Therefore, all gears including the gear 2 are rotated alike in the identical direction at an equal speed. In this place, rotation imparted to the driven shaft B from the other one cannot be transmitted to the drive shaft A.

Filed: 1987-10-21
Abstract: PURPOSE:To obtain a pseudo telephotographic camera whose zoom ratio is large by altering the focal distance of an eye piece lens group according to the size of the visual field frame of a finder. CONSTITUTION:The image-forming surface of a photographic lens 1 is near the visual field frame 4 and a desirable trimming state can be displayed in the finder by making the size of the visual field frame 4 smaller.
