Abstract: PURPOSE:To maintain the uniform shape and size of a condensed spot by installing an objective lens in such a way that the position of the node of scanning formed by the laser beam emitted from the final relay lens of a laser beam processing machine is made focal position. CONSTITUTION:The laser beam 2 emitted from a laser oscillator 1 is scanned in an arrow (a) direction by a galvanomirror 3 and is scanned in an arrow (b) direction after an intermediate focus 6 is formed in the position of an intermediate slit 5 by passing the beam through the relay lens 4. The beam past the relay lens 7 forms the node of scanning (the place where the position of the beam does not change with respect to light deflection) in the position 8a. The objective lens 8b having a substantially large aperture is provided below the node 8a and the position of the node 8a is matched with the focus of the lens 8b. The beam emerging from the lens 8b is made perpendicular to the principal plane and a consensed spot 9 scans on a sample 10 in an arrow (c) direction. The shape and size of the spot are thus made the same in any place and the precision laser processing is made possible.

Title: Refuse collecting vehicle and control device thereof
Inventor: IWASAKI MINORU
IPC: B65F3/20
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To prevent a refuse discharge plate from unnecessarily moving back, when the refuse discharge plate is automatically moved back in accordance with lowering of a tail gate after refuse discharging, even a worker repeats switch operation for lowering the tail gate. SOLUTION: If a first changeover switch SW is turned to the tail gate lowering side, after refuse is discharged a second solenoid SOL2 is supplied with a current so that moving back of a refuse discharge plate and the actuation of timer TM start. After a predetermined time passes, if a time limit contact 20 of timer TM is closed and a self holding relay KR2 is held on the set side, the tail gate beings lowering and the refuse discharge plate stops moving back. The refuse discharge plate does not move back again, since the self holding relay KR2 is held at the set position until a second changeover switch SW2 starts an operation for moving the refuse discharge plate forward, even the first changeover switch SW is repeatedly operated.

Abstract: PURPOSE: To cool a molded article alone without cooling an entire mold and thereby to save energy by cooling the molded article by means of a cooling medium passed through a core bar on the occasion when the pipe is molded in a cavity formed by the mold and the core bar.  
     CONSTITUTION: The resin 14 is molded in compression, while the cavity 13 formed by the upper and lower molds 10 and 11 and the core bar 12 is heated by heaters 10a and 11a. And the molded article is cooled by passing the cooling medium through the passage 12a of the core bar 12. Since the molded article alone is cooled without the entire molds 10 and 11 being cooled in this way, a time required for cooling the molded article, as well as a time required for heating the molds can be shortened, and also the waste of energy can be avoided.

Title: Estimation method for delay spread of radio received signal
Inventor: YAMAGUCHI AKIRA
IPC: H04B7/26
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a method in which the delay spread of a radio received signal is estimated simply and precisely. SOLUTION: First, a received-signal instantaneous levelchange characteristic and a power delay profile characteristic are measured (10). A regression expression with reference to the normalization delay spread of a relative level is computed on the basis of them (20). On the other hand, in a place in which a delay spread is to be estimated, a received-signal instantaneous level change characteristic in a proper receiving bandwidth is measured (60). A relative value is computed on the basis of the center value of a received-signal instantaneous level with reference to a prescribed cumulative probability is computed (40). A normalization delay spread corresponding to the relative level is computed by using the regression expression (50). The normalization delay spread is divided by the receiving bandwidth, and a delay-spread estimated value is obtained (100).
