Title: Dust proof unloader
Inventor: GO HIROMI
IPC: B66C3/02
Filed: 1985-09-27
Abstract: PURPOSE:To protect materials when unloaded from the wind blow which comes from the direction where no windbreak is located so as to improve the dustproof performance by allowing a grab bucket to open to the direction where the grab bucket moves in and out. CONSTITUTION:A grab bucket 3 is allowed to open toward the direction where it (3) moves in and out. In this configuration, when materials are unloaded from the grab bucket 3 with the bucket 3 opened into a hopper 4 of an unloader, the circumference of which is surrounded by a windbreak 6 except a place where the grab bucket 3 moves in and out, the opened grab bucket 3 prevents the wind from coming in through the space where the grab bucket moves in and out. This configuration prevents materials when unloaded from being blown off by the wind permitting no dust to be accumulated.

Filed: 1984-10-12
Abstract: PURPOSE:To reduce consumption of electrode and to improve machining preci sion by preparing minute carbon powder impregnated with carbohydrate, fats and oils, nonionic active agent, or mixture thereof and dispersing the same uniformly in machining liquid. CONSTITUTION:When work such as SKD 11 steel is finish-machined by discharge machining using a graphite electrode to obtain the surface finish precision of 8muRmax, the electrode consumption rate is 116% in case A in which conventional pure water is used as machining liquid, and it is 32% in case B in which pure water is mixed with a nonionic active agent. If 6% of carbon powder impregnated with fat is mixed in the machining liquid and uniformly dispersed, it is about 6% in case A and about 2% in case B. In other words, this is remarkably effective in comparison with the liquid only mixed with carbon powder. Therefore, machining precision is also improved.

Title: Pattern forming method
Inventor: NOZAWA SATORU
IPC: G03F1/70
Filed: 1987-08-27
Abstract: PURPOSE:To form a pattern whose joint accuracy is high, by forming the pattern by superposing each of plural pattern parts whose joining positions are different from each other, distributing the energy radiated thereby to respective groups of plural groups, and executing the radiation to each group by using this energy. CONSTITUTION:Joining positions 13b-13d of respective groups of plural pattern parts 11c and 11d, 11e and 11f, and 11g and 11h of plural groups are allowed to be different from each other. Accordingly, even if the dislocation is generated in each of the pattern parts 11c and 11d, 11e and 11f, and 11g and 11h in the joining positions 13b-13d of some group, no dislocation is generated in other group. Also, as for the energy to be radiated to each group, the energy which is radiated in order to form a pattern 11 is distributed to respective groups of plural groups, therefore, no pattern is formed by only the energy of the quantity radiated to the dislocated part in the pattern parts 11c and 11d, 11e and 11f, and 11g and 11h. In such a way, the dislocation generated in the pattern 11 formed by superposing each group becomes small.
