Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To preferably apply constant pressure to a grinding tool regardless of the abrasion quantity of an abrasive by using the fluid pressure for moving a pressure side moving flange for the pressing force applied to the grinding tool. SOLUTION: A tensile spring 13, by feeding compressed air, for example, from the feed/discharge hole 6a of a fixed flange 6, applying air pressure, for example, between a pressure side moving flange 8 and the fixed flange 6 from the neutral position, and moving the pressure side moving flange 8, shrinks bellows 11. The spring constant of the tensile spring 13 is determined so that the spring force of bellows 10 acting in the direction to shrink the bellows 10 is balanced with the force by the tensile spring 13. By determining the spring constant of the tensile spring 13 the pressing force applied to the grinding tool 2 becomes only the air pressure, and invariably stable pressure force is obtained.

IPC: H01L21/60
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To facilitate formation of a ball grid array and prevent lack of solder terminals and generation of short circuits between electrodes, by overlaying a solder plate having a specified thickness on the terminal surface of an electronic component, cutting the solder plate into a large number of solder small chips and arranging each of the solder small chips on each electrode. SOLUTION: Lattice trenches 5 having almost V-shaped sections which surround the respective electrodes 4 are formed on a terminal surface 3 of an electronic component 1 of a FBGA. A solder plate 9 having a specified thickness is overlaid on the terminal surface 3 and is pressed and cut by using a lattice cutting tool 8 having blades 7 coinciding with the lattice trenches 5. Solder chips 10 are arranged on the respective electrodes in the state of pressure contact. After that, solder terminals 11 are formed on the respective electrodes 4 by thermal treatment, and a ball grid array is formed by using the solder terminals 11.  As a result, a large number of solder balls which are inconvenient for handling in the conventional case are made unnecessary, and small solder chips 10 are supplied to all of the electrodes 4 without omission, so that generation of the electrodes 4 lacking solder chips 10 can be prevented.

Abstract: PROBLEM TO BE SOLVED: To restrain eddy current loss by supporting an electromagnetic pick-up type rotary sensor penetrating a mounting hole in a metal support so that the most part of a built-in magnet approaches the inside of the support from the thickness center thereof. SOLUTION: An O-ring for a seal is fitted on the outer peripheral surface of a rotary sensor 21. The rotary sensor 21 penetrates a rotary sensor mounting hole 31 provided in a metal support 30 from the outer side 30A side toward the inner side 30B to be fixed to the support 30 with a mounting bolt 33. Then, the position of a magnet 24 built in the fixed rotary sensor 21 is adapted to approach the inner side 30B rather than the outer side 30A. The end face of non-pole piece 23 side of the magnet 24 is disposed to approximately coincide with the center A of the thickness of the support 30 so that the end face of a pick-up coil 26 at the opposite side to the tip 23A of the pole piece is disposed to coincide almost with the inner side 30B. Thus, the magnetic resistance between the tip 23A of the pole piece and the magnet 24 is reduced, so that the output efficiency can be improved.

Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To suppress the remaining of processing surface roughness on an embossed surface by preliminarily applying surface roughness to a cavity surface so that the ratio of surface roughness with emboss depth becomes a predetermined value. SOLUTION: In producing a mold, cutting processing and/or discharge processing are applied to the cavity surface (a) of a mold and, subsequently, embossing processing is directly applied to the processed cavity surface without applying polishing finish thereto. In order to remove a polishing process, in the processing of the cavity surface of the mold, surface roughness Rz is controlled corresponding to the emboss depth (z) of embossed patterns (b) to be formed. The ratio of the processing surface roughness Rz of the cavity surface (a) of the mold to emboss depth (z) is set to 0.6 or less, desirably, to about 0.2. In the case of 0.2, the transfer of the remaining of the processing surface roughness Rz of the cavity surface (a) of the mold to an embossed surface to a resin product becomes an unrecognizable degree.

Filed: 1992-03-26
Abstract: PURPOSE:To provide a delay switch capable of turning off loads with a delay during operation of a switching element by enabling one load to be controlled from two places. CONSTITUTION:When a make break contact S1 is closed with a changeover switch SW switched to a second contact (b), AC power is supplied to a fan 3. A delay circuit B turns a switching element Q1 on in response to the detection output of a current detection circuit 1, the switching element Q1 being connected in parallel to a series circuit of the primary side of the current transformer CT of the current detection circuit 1, a contact S2 and the fan 3. When the make break circuit S1 is opened, the current detection circuit 1 produces no detection output, but the delay circuit B holds the switching element Q1 in an ON state for a certain time using a timer circuit 5 and a conduction holding circuit 4. Therefore, operation of the fan 3 is stopped after a delay of the time. When the changerover switch SW is switched between the first contact (a) and the second contact (b) with the make break circuit S1 opened, the fan 3 can be turned on and off.
