Abstract: PURPOSE:To display a sure regeneration function by forming a pilot oil room for a stroke control means mechanism so as to be able to connect to a tank through a sequence valve and making the full stroke position of a spool in two steps. CONSTITUTION:When a main circuit pressure is below a prescribed value in the case of a light load operation, the pilot pressure of a pump 2 acts on the pilot oil room 17 of the stroke control means mechanism 35 of a hydraulic change over valve 56 stably through a throttle part 54 and the one way moving amount of a spool 33 in the hydraulic change over valve is controlled surely and a regeneration confluence operation for a hydraulic cylinder 5 is performed stably. When the main circuit pressure exceeds the prescribed value in the case of a heavy load operation, a sequence valve 55 performs change over operation and a pilot oil room 17 is connected to a tank. At this time, the hydraulic cylinder 5 is in its stretched status, but the spool 33 is moved additionally and the regeneration function in the hydraulic circuit is stopped. No pressure acts on the pilot oil room 17 and the pilot pressure from the pilot valve acts on the pilot oil room 37 and any unstable status does not take place. Therefore, hunting phenomenon does not occur in the hydraulic cylinder.

Title: Target direction determining mechanism
Inventor: FUNADA YOSHIMARU
IPC: G01S3/80
Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To dispense with a searching function of a radio wave sensor and to lessen power consumption by a system wherein signals from nondirectional acoustic sensors are whitened when it is detected that a target sound increases to a predetermined level or above, and directional angles formed by the target sound and the reference coordinate axes are computed from the signals whitened. SOLUTION: A sound generated by a target is detected by an acoustic sensor 1 and given to a computer 13 through an A/D converter 7, while it is given to a comparator 15. When an input signal exceeds a reference voltage, the comparator 15 sends a signal of a command to start computation of the direction of the target to the computer 13. The computer 13 removes low-frequency components from acoustic signals from individual acoustic sensors and takes out high-frequency components therefrom (whitening) and, using the white signal from the acoustic sensor 1 as a reference white signal, executes a processing of mutual correlation between the reference white signal and the white signal of each acoustic sensor. It calculates the direction of the target from mutual time relations and transmits values thus obtained to a computer 12.

Title: Clv controller
Inventor: SHOGAWA TAKUYA
IPC: H02P29/00
Filed: 1989-09-13
Abstract: PURPOSE:To eliminate unnecessary arithmetic for pseudo CLV control by calculating a frequency dividing ratio for each position interval where the integral part of a frequency dividing ratio calculation output is switched. CONSTITUTION:When a record starting position r0 to start recording is detected, a current recording position (r) is detected afterwards while executing prescribed recording. The recording position (r) is compared with the record starting position r0 and in the case of r>=r0, the frequency dividing ratio is calculated. A processing is executed to count fractions less than a decimal point as one to such a frequency dividing ratio calculation output (n) and the output (n) is made integral and added to a variable frequency divider 3. Then, the CLV control is executed. Simultaneously, the recording start position r0 is changed to r+ r and the above mentioned operation is repeated. In such a case, the  r is the change amount of the recording position (r) to be moved until the frequency dividing ratio calculation output (n) is changed only by 1, and the  r is a fixed value. Since this  r is an interval for the calculation output (n) to be changed by 1, the pseudo CLV control can be executed without repeating the useless calculation in the middle of operation.

CONSTITUTION:A flame-holding wall 3 is formed by a heat resistant material around a burner port surface 1 formed with a plane, and the flame stabilizing wall is formed in a discontinuous state in spots. A number of burner ports 2 are formed in a checkered state in the burner port surface, a pressure uniformizing space is formed at the back of the burner port surface, and a blower 8, feeding premixing gas, is situated in the pressure uniforming space. In which case, the size of the burner port 2 of a burner is set to 1.2-2mm to increase a combustion amount per a unit area of a burner, and a distance between the centres of the adjoining burner ports is set to 3-5mm, so that lift is difficult to occur. A flame-holding wall 3 having a height of 8-15mm is formed around the periphery of a burner surface, and if a distance between the outer periphery, positioned nearmost the flame-holding wall, of the burner port and the flame stabilizing wall is set to 2mm or less, lift of flame can be effectively prevented from occurring. Further, positioning of a flow-straightening plate 5, having an opening 4 with a total area equal to that of the burner port, in a position situated 3-10mm away from a burner port surface bottom part on the the upper stream side of the burner port, enables prevention of the occurrence of vibration combustion.
