Patent JP-H04140418-A (JP)
Title: Piston structure of diesel engine having subchamber
Inventor: WAKASA AKINORI
IPC: F02B3/06
Filed: 1990-09-28
Abstract: PURPOSE:To avoid the trouble that a struck scar is generated by the interference between the surface of a piston with a subchamber constitution member which shifts in the cylinder direction, by forming a recessed part connected to a grove part, at the part corresponding to the below of the subchamber constitution member on the top surface of the piston. CONSTITUTION:When air and fuel are mixed in an eddy current chamber 2 and combustion is carried out, combustion gas is injected into a main chamber 1 from an injection port 13a. At this time, the combustion gas collides with the top surface 6 of a piston violently, and is guided to a trench 6a. The half combusted gas forms an eddy current in a main chamber 1, because of a recess 6b and a recessed part 6c which are formed in connection with the trench 6a, and is sufficiently mixed with air, and diffusion combustion is carried out. While, even if a piston 5 reaches a top dead center position, the interference between an insertion member 13 which shifts by the generation of a tilt theta in the cylinder direction and the top surface 6 of the piston is prevented, since a nearly arcuate recessed part 6c is formed in correspondence with the outer peripheral shape of the insertion member 13, under the insertion member 13 on the top surface 6 of the piston.

Filed: 1994-10-28
Abstract: PURPOSE: To utilize effectively a transmission resource by detecting a calling state from a terminal equipment of a slave station and confirming an idle capacity of a transmission line when a time slot is allocated to the slave station. CONSTITUTION: A slave station 3 detects a calling state from an ISDN terminal equipment 4 of its own station by a control section 10 and it sends a signal requesting how to allocate time slot with respect to a master station 1 to an interface section 8.

Title: Memory device
Inventor: TAKEISHI MASANAO
IPC: G06F15/16
Filed: 1985-11-25
Abstract: PURPOSE:To prevent previously the malfunction of a memory device by securing such a constitution where a processor set under a processing mode holds the access right to a memory until the processing equivalent to the maximum processing bit number contained in the using processor is through. CONSTITUTION:A bus selecting part 43 is connected to the lowest bit line 36a among the address lines 36 of a processor 38 set at the 8-bit side through a bus control part 42. Thus the even number of an address A2 can be discriminated in case the processor 32 acquires the access right to a memory part 41 by supplying the lowest bit signal A0 to the part 43. At the same time, the bus switch signal BC outputted from the part 43 is changed in response to an odd- even discriminating action using the signal A0. The signal BC is not changed while the signal A0 of the line 36 is kept at 0. Thus the signal BC is held to inhibit the bus switching action. Then the bus switching action is possible after the signal A0 is set at 1.

Filed: 1986-11-08
Abstract: PURPOSE:To automatically compensate accuracy to the variation part of a flaw detection parameter, by feeding back the deviation of the average value and set value of a fluorescent powder flaw detection image pickup signal to the image pickup signal, and generating alarm signals when the deviation exceeds a prescribed range. CONSTITUTION:The fluorescent powder flaw detection image pickup signal from an industrial camera 1 is supplied to a flaw judging circuit 4 through the A/D converter 3 of a signal processor 2 and a judge result is supplied to a computer 13. The output of the converter 3 is averaged at every one line by an averaging circuit 5 and subjected to subtraction processing along with the set average value when a flaw detection parameter from a setting device 7 is normal by a subtraction circuit 6 to calculate a deviation value which is, in turn, fed back through a D/A converter 8. The deviation is compared with a set lower limit value by a comparing circuit 11 and, when the deviation value is out of an upper and lower limit value range, an alarm 12 is started. By this method, accuracy is automatically compensated to the slight variation part of a flaw detection parameter such as the sensitivity of the camera 1 and flaw detection is performed easily and stably with high accuracy.
