IPC: F02F1/38
Filed: 1988-01-28
Abstract: PURPOSE:To facilitate positioning of a core for intake and exhaust air ports and to reduce manhour for assembling a mold by integrating the core for intake and exhaust air ports in a cylinder head for the whole cylinder. CONSTITUTION:The core 1 for intake and exhaust air ports is inserted between cope 2 and drag 3 parts in pattern divided into two at upper and lower parts made of metal for shell core. Each core 1 for intake and exhaust air ports is integratedly connected with the whole cylinder as covering, the outer peripheries of the cope 2 and drag 3 parts in the pattern, so that alignment of intake and exhaust air holes 4, 5 in the drag 1 and the intake and exhaust air parts 6, 7 in the core 1 can be automatically executed.

Abstract: PROBLEM TO BE SOLVED: To provide a powder-ignition testing apparatus in which a dust cloud of uniform density is formed to find the minimum ignition energy of a powder simply and with good accuracy, by which an ignition test can be performed continuously a plurality of numbers of times and in which time and labor spent for the ignition test can be reduced sharply. SOLUTION: When an ignition container 1 and its fixation part 2 are vibrated by a vibrating device 3, a sample container 40 which is installed inside the ignition container 1 is vibrated. As a result, a powder to be tested (a sample) which is filled into the sample container 40 falls through a wire net 41, and a dust cloud is formed. An ignition test of the dust cloud is performed by a discharge spark generated by a high voltage applied to a discharge electrode. When the dust cloud is not ignited, discharge energy is increased stepwise. The ignition test is performed repeatedly until its ignition is confirmed. In succession, the control switch 33 of the vibrating device 3 is turned, and the amplitude of its vibration is increased. The ignition test is performed repeatedly until the ignition is confirmed.  When the ignition test is repeated, the minimum ignition energy of the powder to be tested is found.

IPC: G06F1/00
Filed: 1988-01-29
Abstract: PURPOSE:To guarantee various information by extracting power turn-off signal information stored in a memory at the time of requesting key entry data in an operation program being traveled, returning the information to the operation program and deciding the processing state of a self-operation program by the information to turn off a power supply. CONSTITUTION:When a power supply turn-off key 1a allocated on a keyboard 1 is depressed, a power supply turn-off signal outputted in accordance with the key depression is temporarily stored in an information storing memory 3 as a power supply turn-off signal information corresponding to the key 1a. When a traveling application program 5 requests data to a key data processing part 4 to be a control part, the processing part 4 checks the memory 3, and when its stored contents are the power supply turn-off information, returns the information to the program 5. Consequently, the application program 5 decides its processing state, and at the time of deciding the availability of power turn-off, commands a system turn-off processing part 6 to turn-off the power supply. Thus, the contents of a main memory storing the operation program are not volatiled by power supply OFF.

Abstract: PURPOSE:To 'unable' information indicating the data length in the transmitted data and to shorten the processing time necessary for the receiving control by providing a circuit which counts the data length of the receiving data in the receiving buffer control part of each node in the data transmitting system and a receiving data count register holding counted data length. CONSTITUTION:The data received through a receiving transmission line 20 from the other-side node are checked for their node addresses and mis- transmissions in a receiving transmission line access control part 22. When there is no mis-transmission, the said control part 22 writes the receiving data into a receiving buffer memory 23 to store, counts the data length of the receiving data, and holds the data length of the receiving data at a received data count register 24 at the time when the write-in of the data to the receiving buffer memory 23 is over. A receiving buffer control part 26 executes the receiving DMA-starting to a receiving DMA circuit 25, DMA-transfers the received data in the receiving buffer memory 23 to main memory 2B for the data length held in the receiving data count register 24 and generates an interruption, thereby completing the receiving action.
