Title: Pga dismounting jig and method
Inventor: HARA SATORU
IPC: H01L23/12
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To dismount a PGA from a printed board without applying any unreasonable force to the pins of the PGA and in a common timing with all the pins, by interposing an elastic member between the rotary knob of the screw shaft of a PGA dismounting jig and its jig base to give always to the screw shaft an opposite-direction force to the printed board. SOLUTION: In a circular hole 5 of a base plate 3 of a jig base 2, a screw shaft 6 is mounted in a rotatable, slide-able and engaging way at whose lower end a terminal plate 7 with a concentric screw hole 8 with it is provided and to whose upper end a rotary knob 9 is fastened. Further, interposing a coil spring 10 between the rotary knob 9 of the screw shaft 6 and the base plate 3 of the jig base 2, a force is applied upward always to the screw shaft 6. Therefore, when a PGA 11 is dismounted from a printed board 13, this dismount is performed only by utilizing a natural vertical spring force to deal with it without applying any unresonable force to the pins of the PGA 11 and eliminate such troubles as the bends and damages of the pins.

Title: Input output changeover device and matrix switcher controller
Inventor: MURATA YASUHIRO
IPC: H04N5/268
Filed: 1995-02-27
Abstract: PURPOSE:To manage flexibly the system by converting each information of virtual layers and input/output entered by an entry means for virtual information into each information of physical layers and input/output and giving the converted information to a matrix switching means. CONSTITUTION:Matrix switchers MS2A, 2B are switched based on each information of virtual layers, input/output entered by the control panel 3 of a matrix switcher(MS) system 1. The switching result is displayed by the lighting of a lamp of the panel 3 or the like, a system controller(SC) 4 gives the signal from the panel 3 to a system management section 5, which gives its reply signal S2 to the panel 3. Furthermore, the management section 5 converts each virtual information in terms of the signal S1 as to the position of a cross point into a signal S3 being physical information and gives the converted signal to both the matrix switchers and converts inversely the physical information into the virtual information and gives it to the SC 4. Thus, the switching state of the matrix switchers is grasped on the panel 3 thereby allowing the operator to manage flexibly the system.

Title: Empty can crushing machine
Inventor: YOKOYAMA MASAHIRO
IPC: B21D43/00
Filed: 1995-02-28
Abstract: PURPOSE: To correctly fold up an empty can without displacing the empty can in a time of pressing a crush lever by arranging a positioning member of the empty can on a base stand and forming two projection bars to mount the empty can in truncated chevron shape on this both side. CONSTITUTION: When an empty can A is mounted laterally on two projection bars 12, 12, the empty can is abutted on a positioning member 11 and stopped. When a 1st crushing lever is lowered individually and the empty can A is crushed, because the projection bars 12, 12 are inclined forward the internal side, the component of force to press the empty can A to the internal side is generated, the empty can A is going to move inside at the contact position with the projection bars 12, 12, so the central part is crushed correctly with the 1st crushing lever. The 1st crushing lever is raised and connected to a 2nd crushing lever with an engaging member, in this state, the 1st crushing lever is again lowered, and the empty can A is crushed so that the both side cap parts are folded.  Therefore, even if the empty can A is mounted roughly on the projection bars 12, 12, the empty can A can be folded correctly without being displaced.

Title: Detection of abnormal condition of conveyer
Inventor: NAGAO MASATO
IPC: B65G43/02
Filed: 1980-05-16
Abstract: PURPOSE: To make possible the detection of the abnormal condition such as the vertical crack of a conveyer belt by a method wherein ultrasonic beams are allowed to cross the conveyer belt in the direction of its width along the surface on its incoming side and the beams are radiated while they are being focused by means of a horn radiator.  
     CONSTITUTION: When a metal piece 5 hits a shoot 4 and stays therein after it has stuck in a conveyer belt 6, the conveyer belt 6 is damaged by the metal piece 5 to cause a vertical crack 11. Objects 3 to be fed fall through the crack 11 and accumulates on the incoming side 6B of the conveyer belt 6, so that they obstruct the ultrasonic beams B radiated from an ultrasonic beam transmitter 9. As a result, the strength of the ultrasonic beams inputted to a receiver 10 is reduced and the occurrence of a vertical crack 11 can be detected depending on the beam amount reduced. A conical horn is used as the ultrasonic beam transmitter to improve the focussing of ultrasonic beams B.

Title: Tilting pad bearing
Inventor: YOSHIOKA MASAHIRO
IPC: F16C17/06
Filed: 1983-04-15
Abstract: PURPOSE:To avoid bad effects due to swelling and to increase load-resistance by fixing a pivot member directly on a bearing slide member. CONSTITUTION:A pad 1 which is a bearing slider is formed by a bearing sliding material which is thick and has a large coefficient of swelling or thermal expansion. A pivot 3 is disposed on the back of the pad 1 at a side contact portion S. The average surface pressure of the contact portion S is designed in such a manner as to be enough lower than the strength of the pad 1. In this arrangement, the pad 1 will not be pressed to be broken by load. During operation, water film pressure is produced on the pad 1, so that a portion of the pivot 1 that is apart from the central part thereof is deformed downward to form a water film wedge, thereby easily forming a water film.

Title: Cassette carrier
Inventor: OZAWA KEITAROU
IPC: G11B15/17
Filed: 1983-04-15
Abstract: PURPOSE:To inhibit the shift of a cassette carrier when a cassette is mounted on the carrier in a wrong posture and in a wrong direction, by providing the 1st and 2nd members which are actuated by the cassette mounted in a correct direction. CONSTITUTION:A cassette carrier shift preventing member consists of a slider 78 which can slide toward the rear part of the right wall part 70b of a cassette holder 70 and in directions of arrows K and L. A slider 79 provided at the back of the left wall part 70c of the holder 70 can slide also in directions of arrows K and L. When no cassette is mounted on a cassette carrier, the carrier is lifted to have a contact with a projected part. Both sliders 78 and 79 move down toward the arrow L when the cassette is mounted completely on the carrier in a correct posture. Then the cassette carrier can move horizontally. In case the cassette is mounted on the carrier in a wrong posture, one of the sliders 78 and 79 cannot move to the arrow L direction. Thus the cassette carrier has no shift.

IPC: B21D13/02
Filed: 1979-05-29
Abstract: PURPOSE: To form the corrugated sheet with high accuracy of the pitch between respective waveforms by subsequently forming multiple waves with the wave already formed as a reference position.  
     CONSTITUTION: After one wave 13 is formed by punches 7 and 8, guide members 14, 19 assume the state that they are deviated to the right side and feed the work 11 rightward by l/2. The wave 13 just formed comes to the position opposing to the protruding flight 14a of the guide member 14 and the groove 19a of the guide member 19. When a die 8 is lowered in this state, the wave 13 just formed is gripped by the guide members 14, 19 from both sides and performs the accurate positioning of the work 11. Thence, the die 8 is further lowered to press the work 11 by the same and punch 7, whereby a new wave 13 is formed. At this time, the guide members 14, 19 move leftward against the elastic force of coil springs 17, 21 while gripping the previously formed wave 13, and this completes the forming of one wave 13.
