Title: Starter for carburetor
Inventor: TSUTSUI KATSUHIKO
IPC: F02M1/08
Filed: 1988-10-31
Abstract: PURPOSE:To permit the smooth start by installing a starting fuel passage branched from a fuel passage and arranging an opening/closing valve which is perfectly opened only in the case when the fuel pressure is less than a certain pressure and permitting the injection of fuel only in the initial stage of start. CONSTITUTION:When an engine is revolved for starting, a portion of the fuel is discharged into a fuel passage 8A is introduced into a pressure chamber 29 through a starting fuel passage 30A, but since the pressure is less than the set pressure, an opening/closing valve is not closed, and fuel is injection-supplied into an intake passage 2 and smooth start is permitted. When the number of revolution increases, the fuel pressure in the pressure chamber 29 increases, and when the pressure exceeds the set pressure, a dividing body 27 shifts upward, and the opening/closing valve 31 throttles the opening area of a valve seat 32, and closes the opening, and the supply of the starting fuel is automatically suspended. Therefore, the engine start can be facilitated without using a new pump.

IPC: B41M5/34
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a dichromatic heat-sensitive recording medium that a defective color developed part such as blur or haze scarcely occurs and has an excellent preservability of a recorded image. SOLUTION: The dichromatic heat-sensitive recording medium selectively color develops red or black color under the control of thermal energy, and comprises a developer, red leuco dye having compatibility with the developer to color develop red color at a low temperature by the operation of the developer, black color leuco dye having lower compatibility with the developer than that of the red leuco dye to color develop black color at a high temperature by the operation of the developer, and a single recording layer containing binder as a main ingredient on a support.  Since the medium has the structure that the low temperature color developing layer and the high temperature color developing layer having different color developing temperatures are sequentially laminated on the support, defective color developing part such as blur or haze scarcely occurs, and since an erasing agent for operating at the time of high temperature heating is not applied, the sufficient preservability of the recorded image is provided.

The pile 4 is erected, driven in by the impact of the vertical movement of the hammer of an upright driving machine onto the earth surface and stopped in an appropriate position. Each time the pile 4 descends, the peripheral surface is inserted into the inclined 'U' formed groove 3 receiving the pressure of the earth as well as upward pressure is acted upon the soil layer driven to the earth insertion hole 1 simultaneously. The soil layer is compressed by this pressure, expanded while becoming hard soil, and stops supportingly on the soil layer surface in the form of bonded X. As a result, the pile is prevented from descending by utilizing the pressure flowing into the 'U' formed grooves.
