Title: Seal manufacturing device
Inventor: HATTORI YASUHIRO
IPC: G03D13/00
Filed: 1990-06-11
Abstract: PURPOSE:To obtain an excellent full-color image without requiring glue by uniting and pressing a photosensitive pressure-sensitive medium which is coated with a developer and a seal base material which has cohesive layers on both surfaces. CONSTITUTION:The microcapsule paper 4 which has a latent image and a developer layer 27 on the latent image and the base material seal 10 are put one over the other and pressed by a couple of developing rollers 13. Internal materials flows out of microcapsules with the pressure and react on the developer layer 27 to color. At the same time, the cohesive surface of the seal base material 10 contacts the developer layer 27 and is pressed. At this time, the cohesive strength operating between the developer layer 27 and seal base material 10 is much larger than the sticking force based upon the developer layer 27 and microcapsule paper 4, so the coloring internal materials and developer layer 27 are transferred to the seal base material 10. Consequently, the excellent full-color image can be obtained without requiring any glue.

IPC: F01P11/02
Filed: 1995-06-20
Abstract: PURPOSE: To suppress a temperature increase by comparing a covered distance by a vehicle with a limit distance determined such that a coolant temperature remains under the opening temperature of a thermostatic valve not acted upon by current (i.e., under the boiling temperature), and by acting upon the thermostatic valve by current from the vehicle start as long as the covered distance after the vehicle start is shorter than the limit distance so as to open the valve below the boiling temperature. CONSTITUTION: A limit distance is determined such that a coolant temperature in a cooling circuit 14 of an internal combustion engine 10 remains under the boiling temperature in normal driving operation. During covering the whole limit distance, a thermostatic valve 16 is acted upon by current so that the thermostatic valve 16 introduces a coolant flow in the cooling circuit 14 of the internal combustion engine 10 through a radiator 11 with the coolant temperature below the boiling temperature. Thereby, the coolant in the cooling circuit 14 of the internal combustion engine 10 is not heated over the boiling temperature corresponding to a surrounding pressure. As a result, the coolant reaching into the radiator 11 and its control tank 12 has a low temperature not to be discharged.
