Title: Inspection of connection state for electronic components
Inventor: KOJIMA AKIO
IPC: G01N25/72
Filed: 1983-05-02
Abstract: PURPOSE:To inspect the connection state of electronic components to a printed circuit board at a high accuracy by irradiating a lead of electronic components with an energy beam to detect infrared rays radiated from a conductor pattern. CONSTITUTION:A part 5 of a lead 4 of electronic components 6 carried on substrate 1 is irradiated with an energy beam 7 such as laser beam to observe changes in the time of an infrared rays 8 radiated from a pattern 2. When the connection is normal, as the quantity of heat applied is consumed to raise the temperature of a solder 3, the rising of the infrared rays 8 is slow with time while when it is defective, that is quick because of a quick heat conduction to the pattern 2. Thus, the connection state of electronic components 6 to the substrate 1 can be inspected at a high accuracy.

Filed: 1983-04-30
Abstract: PURPOSE:To prepare the titled product which does not warp nor wave after hot pressure forming, by forming a layer of raw material in string, passing it through a specified process repeatedly to form it into circular or arc shape and taking it out in the annular form. CONSTITUTION:The formed product is prepared on a machine equipped with a rotating movable plate 25 having axes Q1-n and P1-n arranged outside and inside, respectively, on the plate concentrically to the center of rotation and an arm 26 which swings in a radial direction and repeats reciprocating movement. A string material 1 is laid onto the axes Q1-n and P1-n alternately so that a number of strings in a doglegged shape may be linked together in the direction parallel to the periphery to form one layer in one rotation of the plate. Upon formation of one layer, the arm 26 is made to stand still outside the radial direction of the axes P1-n and the movable plate 25 is rotated clockwise to cause winding of the string 1 on the outside to form a peripheral layer. The above operation is repeated until the winding and linking process of the string 1 is completed. When a pressing plate 34 is drawn back and the movable plate 25 is pushed forward to a position shown by two-dot chain line, an annularly formed product for an annular friction plate is removed from the axes.

Filed: 1993-04-02
Abstract: PURPOSE:To transform materials for deep-frying to round shape by rolling the materials, dropped on the rolling part from a feeder, on the surface of the rolling part without handwork. CONSTITUTION:By using the material feeder A, materials covered with batter for deep-frying such as those of fried chicken are fed to the hopper 1 and go to the fryingware B through the straight-going feeder 2, the distributing feeder 3 and the rolling part 4.

The rolling part 4 has an inclined path of inclination degree of 45 deg. to 85 deg. to the horizontal plane. The materials dropped to the rolling part 4 from the end of the distributing feeder 3 are transformed to round shape gradually by the interaction of adhesion to the surface of the rolling part 4 and dropping down during rolling on the rolling part 4. Thus, one can feed materials for deep-frying such as fried chicken transforming to fixed round shape to the frying device B automatically by the simple structure.

Title: Installation method for pipe and steel pipe pile, and steel pipe pile
Inventor: YOSHIDA SHIGERU
IPC: E02D5/28
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To make it possible to install a steel pipe pile having a large diameter and a large length by forming a layer of excavating and a solidifier liquid between sediment ingressed into a hollow portion of a steel pipe column and the peripheral surface of the steel pipe pile, thereby preventing the clogging in the holloow portion of the steel pipe pile accompanied by the penetration of the steel pipe pile. SOLUTION: A cap 4 is adhered tightly to the upper end surface of a steel pipe pile 1 after receiving a pushing force from a working machine, at the same time, a hollow portion in the steel pipe pile 1 is kept to a closed state. By pushing in while rotating the cap 4, the inner pressure of the hollow portion rises as the steel pipe pile 1 is settled down, an excavating and solidifying solution 3 descends along the inner peripheral surface of the steel pipe pile 1, and an excavation claw 2 is pushed in a gap in the ground excavated. The excavating and solidifying solution 3 pushed into the excavated portion is further moved around the side of the outer peripheral surface of the steel pipe pile 1 and rises to the ground surface side through the outer peripheral surface of the steel pipe pile 1.  By doing this, the amount of the supply of the excavating and solidifying solution 3 is controlled, and the excavating and solidifying solution 3 can be scattered over the inner and outer peripheral surface through the whole length of the steel pipe pile 1 sunk and settled.

Abstract: PURPOSE:To enable radar equipment to change its transmitting frequency at a high speed without losing its moving target detecting function by producing the synthesized signal of two signals modulated by different modulation functions by modulating local signals which are coherent sine wave signals. CONSTITUTION:Local signals generated from a local transmitter 21 are amplitude-modulated by means of an amplitude modulator 27 and supplied to a two-frequency forming device 29 together with local signals generated from another local transmitter 23. The device 29 generates synthesized signals of sum and difference component and a transmission-reception antenna 12 repeatedly transmits the synthesized signals and, at the same time, receives reflected waves from a fixed or moving target. The received signals are supplied to a two-signal MTI processor 36 after the signals are subjected to low-noise amplification 31. The processor 36 finds the difference between the two signal components modulated by different modulation functions after separating the received signals into the two signal components, removes reflected signals from a fix clutter by finding the difference between the two signal components, and extracts the signal component which is frequency-deviated by the moving target. Then a moving target display device 4 displays the extracted signal component.
