Filed: 1986-10-17
Abstract: PURPOSE:To enable the cost to be cheap reduced providing a less number of sensors for detection, by detecting a bucket for whether or not it is in moving so that work is decided to be stopped. CONSTITUTION:A sensor 7, provided in a bucket, detects the bucket to be moved or stopped, outputting a signal of moving or stopping to a controller 18. A control means 17 is switched to a position, in which the control means 17 intervenes in the action of an engine control device by an output signal from the controller 18 based on a stop signal of the bucket controlling an instruction engine speed so as to be in a low speed, and to a position in which the control means 17 intervenes not in the action of the engine control device by an output signal from the controller 18 based on a moving signal of the bucket. In this way, stoppage of work can be decided by detecting whether or not the bucket is in moving through the sensor 7, accordingly, the necessity for providing a sensor, for detecting whether or not a control lever is placed in the neutral position, in all the control levers is eliminated.

Title: Four-phase psk modulation circuit
Inventor: TAKAGI HITOSHI
IPC: H04L27/20
Filed: 1987-10-01
Abstract: PURPOSE:To eliminate the duplication of a signal and a discontinuous wave at the changeover of a carrier by storing four carrier signals into four ROMs, using a ROM output by a PCM input signal and using a D/A conversion circuit so as to convert an analog signal thereby keeping the phase difference accurately. CONSTITUTION:A PSK carrier clock signal 1 is subjected to 1/2M frequency division by division by a counter 2 and becomes an address signal 3 of the ROMs 4-7. The ROM 4 stores one period of the carrier sinusoidal wave, the ROM 5 stores the wave at a phase retarded by 90 deg. than that of the ROM 4, the ROM 6 stores the wave at a phase retarded by 180 deg. than that of the ROM 4 and the ROM 7 stores the wave at a phase retarded by 270 deg. than that of the ROM 4. Moreover, a ROM corresponding to the combination of PCM input signals 6, 7 is selected by a decoder 8. A data signal 13 being the output of the ROM is an analog signal, that is, four-phase PSK output signal 16 by a D/A conversion circuit 14. Thus, the phase difference is kept accurately to 0 deg., 90 deg., 180 deg. and 270 deg. and the duplication and discontinuity of the signal at a carrier wave signal switching point is eliminated.

Title: Molding of flashless core
Inventor: KAJIYAMA YOSHINORI
IPC: B22C9/10
Filed: 1993-09-08
Abstract: PURPOSE:To mold a flashless core, to improve working environment and to omit air blow cleaning by forcing core sand into the cavity of a die while sucking the inside of the cavity to reduce the pressure therein in a direction opposite to the direction where the core sand is forced in. CONSTITUTION:A blow head 15 into which thermosetting type shell sand 16 is housed and which is provided with a baffle plate for controlling the downflow thereof is lowered and is set on the die 18 via a negative pressure passage member 22 until the front end of a blow nozzle 19 faces a cavity 17. The pressure in the cavity 17 is then reduced by a pressure reducing pump 31 and a silicone rubber sealing member 25 comes into tight contact with the upper part of the die; thereafter, shell sand 16 is blown by pressurized air 33. As a result, infiltration of the shell sand 16 into the parting planes of the die and generation of a flash are prevented. After a prescribed amt. of the shell sand 16 is forced into the cavity 17, the pressure reduction of the cavity 17 is shut off to stop the blowing. The blow head 15 is thereafter increased and the excess shell sand is sucked into a separating machine 30 by the pressure reducing pump 31 via the negative pressure passage member 22.

Patent JP-S61128371-A (JP)
Title: Vector processor
Inventor: AOKI YUJI
IPC: G06F15/78
Filed: 1984-11-28
Abstract: PURPOSE:To access a main storage device efficiently by changing a part of an address when the same address in a main storage device is accessed plural times continuously to prevent a memory bank in the main storage device from competition. CONSTITUTION:For instance, the 1st-N-th addresses in the main storage device (MS)11 are included in the same bank address (VA). If a starting signal is received from a request control part 2 when an increment value is '0', a counter circuit 4 adds '+1' to the 1st VA in an address sending register 9 and sends the added address to a selecting circuit 8. The control part 2 commands the circuit 8 to select the circuit 4 and the circuit 8 controls so that the 2nd MS address VA+0 is calculated by an address adding part 7, set up in the register 9 and sent to a main storage control part 10. When a '0' detecting circuit 3 detects '0', the control part 2 applies an MS reading data invalidating command to the 2nd-N-th requests. Thus, delay time due to the competition of banks can be removed.

If recording paper is jammed around the heat fixing rollers 163, the turning part is opened to instantaneously remove the cleaning roller 165. Consequently, cleaning, checking and handling troubles, part replacement are readily and surely performed.
