Title: Answer-back system
Inventor: SATO TOMIO
IPC: H04B1/52
Filed: 1988-12-14
Abstract: PURPOSE:To add the answer-back system to an existing loudspeaker sounding system by generating an answer-back signal of a frequency which is set in advance and transferring it to a sound signal generating part side, bringing this signal to frequency discrimination and extracting the answer-back signal, when a voice detecting signal is outputted from an acoustic pressure sensor. CONSTITUTION:A sound signal outputted from a receiving device 11 is received through a transmission line, and also, it is rectified and a power supply voltage is generated, and by this power supply voltage, whether a loudspeaker 10 of a voice loudspeaking part 4 is operated normally or not is checked. Subsequently, based on a result of this check, an answer-back signal of a frequency which is set in advance is generated, and it is put onto a transmission line and sent to an answer-back signal detecting part 14 provided on the receiving device 11 side. By this answer-back signal detecting part 14, the signal is brought to frequency discrimination and the answer-back signal is extracted, a signal for showing whether the voice loudspeaking part 4 is operated normally or not is generated and it is outputted from a transmitting device 12. In such a way, this system can be added easily to an existing loudspeaker sounding system.

Title: Angle correction method for arm and boom of power shovel
Inventor: SAKASHITA TOSHIHIKO
IPC: E02F9/26
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To correct the output of an angle detector that detects the angles of the arm and a boom of a power shovel by a simple work. SOLUTION: The output of an angle detector provided in the joint portion is corrected on the basis of a measured value in an intermediate angle of the runout angle of an arm and a boom 1. The intermediate angle of the runout is an angle that makes the height of a base end pin 5 that pivots the boom 1 and a vehicle body equal to the height of an intermediate pin 6 that pivots the arm and boom 1 in relation to the angle of a joint 3 between the boom 1 and a vehicle body. In the case of the angle of the joint between the arm and the boom 1, it is an angle of the arm pivoted to the head of the boom 1 when hung down. At the intermediate angle of the rount the joint, the rod of a hydraulic cylinder and a bracket pivoted thereto cross each other at an angle near 90 degrees.  Therefore, many of errors in the mounting position and the stroke do not appear as angle errors, thereby making it possible to carry out correct angle correction.

Title: Communication equipment for control data
Inventor: KOUNO TAKAKO
IPC: G05B15/02
Filed: 1989-12-06
Abstract: PURPOSE:To perform the communication of data with high accuracy by using a signal having the pulse length corresponding to the control data for communication and carrying out the error processing based on the pulse length. CONSTITUTION:A transmission data generating means M4 provided to one of both vehicle arithmetic processors produces the transmission data consisting of the control data, the specifying data, off set, and the compensation data. An output means M5 outputs a signal having the pulse length corresponding the transmission data to a signal line M1. Meanwhile a pulse length deciding means M6 of the other vehicle arithmetic processor decided whether a received signal has the pulse length set within a prescribed range or not. If not, an error processing means M7 invalidates the received signal. Thus the noises, etc., superposed on the line M1 are never used as the control data and therefore the communication of data is performed with high efficiency and high accuracy.
