Title: Silver halide photographic sensitive material
Inventor: SUZUKI TETSUYA
IPC: G03C1/74
Filed: 1993-05-27
Abstract: PURPOSE:To provide a silver halide photographic sensitive material which does not cause occurrence of fogging even though it is rapidly dried in a short time by allowing silver halide particles in an emulsion layer to have transition lines, and by drying the emulsion layer in a specific condition after the application thereof. CONSTITUTION:Silver halide particles in an emulsion layer have transition lines, and the emulsion layer is dried in a condition given by the expression during a period in which the moisture content rate of the emulsion layer side decreases to 500 to 50%, where T is a drying time (sec) until the moisture content rate (moisture content/ total hydrophilic colloid weight) decreases to 500 to 50%, and DB is a dry bulb temperature (deg.C) of drying air, which is higher than 28deg.C but lower than 45 deg.C until the moisture content rate decreases to 500 to 50%. If the drying condition is continuously or stepwise changed during a period in which the moisture content rate decreases to 500 to 50% the temperature is exhibited by an averaged value during the period. Further, WB is a wet bulb temperature (deg.C) of drying air until the moisture content rate decreases 500 to 50%, which is higher than 18deg.C but lower than 38deg.C. If the drying condition is changed continuously or stepwise, the temperature is given an averaged value during the period.

Title: Method for cooling of metallic mold for casting
Inventor: MURAKAMI HIDEKI
IPC: B22D17/22
Filed: 1980-09-11
Abstract: PURPOSE:To obtain a defect-free high quality casting by providing a circuit for cooling a metallic mold at all times and an intermittent cooling circuit cooling the same only at necessary times. CONSTITUTION:A plunger 7 is operated to force and pack molten metal into a metallic mold 1. Upon completion of the packing of the molten metal, a stop valve 9 provided to a bypass valve 8 is opened by the signal taken out from a pressure switch 12, by which cooling water is also supplied from the circuit 8 to the mold 1. At the same time, a timer 13 is operated and is timed up at a suitable timing between the solidification of the molten metal up to the removal of a casting, then the signal from the switch 12 is broken to close the valve 9, thereby stopping the supply of the cooling water from the bypass circuit 8. During this time, an ordinary cooling circuit 5 is oprating and therefore the temp. of the mold 1 is uniform without rising excessively above a constant temp. Hence, the mold 1 is maintained relatively at high temp. before the packing of the molten metal completes, and the gas discharged from the molten metal and the air in the metallic mold are prevented from forming water and steam.

Title: Working machine
Inventor: YAMAZAKI HIROAKI
IPC: E02F9/20
Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To improve a working efficiency and working accuracy by adding a rate of shift in accordance with an engine speed to the driving duty value at the time of calculating the driving duty value of an electromagnetic proportional valve unit in use of a given function. SOLUTION: At control driving each boom raising, boom lowering, arm pushing, and arm pulling electromagnetic proportional valve 15A-15D, a corresponding driving duty function is set preliminarily. Next, a calculating duty value is added with a rate of shift according to the engine speed. Then, irrespective of lowering of discharge pressure caused by a throttle down operation, pilot pressure is compensated properly in each electromagnetic proportional valve 15A-15D. Accordingly, a proper operation speed can be ensured regardless of the engine speed. In this manner, the disadvantage of a stoppage or the like at front of the set position is prevented, thus improving the operability.

Filed: 1986-05-30
Abstract: PURPOSE:To accelerate the tool exchanging work by separating the compressing process of a clamp spring and the shifting process of a draw bar so that the force applied to the draw bar can be made small. CONSTITUTION:When a tool 30 is to be unclamped by a spindle head 10, a slide member 16 is shifted by an unclamping cylinder 21 in the unclamping direction against the energizing force of a clamping spring 17. At this time, a draw bar 14 is energized to the clamp position by a holding spring 18, thus a collet 15 is coupled with the tool 30.

Next, the draw bar 14 is shifted by the second cylinder piston rod 21c in the unclamping direction against the energizing force of the spring 18, and the coupling between the collet 15 and tool 30 is released. Accordingly, the force for shifting the draw bar 14 can be made small, and the tool exchange can be accelerated.
