IPC: H03H9/56
Filed: 1989-03-31
Abstract: PURPOSE:To improve the guaranteed attenuation by providing an air gap between a support crystal plate and one major plane of a crystal chip. CONSTITUTION:A shield electrode 23 is formed to a support crystal plate 21 and a void is provided by facing a major plane of the crystal chip 22 and the thickness of a conductive adhesives 32, the distance between them is selected to <=0.5mm thereby, preventing the direct leakage of a signal due to electrostatic coupling between input and output electrodes 25 and 26. Moreover, the crystal plates 21, 22 have the same cut angle and equal thermal expansion coefficient, the production of stress due to a difference of the thermal expansion coefficient is prevented, and the frequency temperature characteristic is kept in an excellent level. Since the adhered direction (X-X line) between the base 20 and the crystal plate 21 and the adhered direction (Z-Z line) between the crystal plates 21, 22 are made orthogonal to each other, both outer circumferential parts of the crystal chip 22 (and crystal plate 21) are used as free ends, thereby improving the warranted attenuation.

The tip and root positions of the lead are thus calculated by the projected images and prescribed ranges in which the tip and the root of the lead 1 of the IC can be put are set as inspection ranges 8, 8,..., 9, 9... respectively according to the tips and the roots. Secondarily, highly precise inspection of the tip and the root parts are performed by using multivalued image data according to respective inspection ranges 8,...9,....  Namely, the lead pitch, coplanarity (flatness), bent from the root to the tip, etc., are calculated so that quality judgement is performed by comparing the standard value set beforehand as necessary.

Title: Yarn breakage detector
Inventor: ISHII MIKITO
IPC: D07B7/14
Filed: 1993-04-09
Abstract: PURPOSE:To provide a detector surely and quickly detecting a yarn breakage even when this occurs in a single fiber. CONSTITUTION:Each yarn F is wound on a tubular rubber layer 3 by the rotations of each bobbin #1-#20 of an under net braider 8 to form under layer 4. The yarn breakage detector 11 is provided with a laser beam sensor 12 consisting of a light projector 16 and a light receiver 17, an amplifier 13, a digital meter relay 14 and a controller 15. When each yarn F passes through the space between the light projector 16 and the light receiver 17 of the laser beam sensor 12, the laser beam which is not reflected on the yarn is received by the light receiver 17. A timing signal and a yarn width signal proportional to the width of yarn F are output. Depending on the both signals, it is determined whether the yarn F has the width of larger than the specified size. If NG signals for an identical bobbin continues for specified times, it is decided that yarn is broken. When yarn F is clung itself and becomes narrow for a short period, it is not judged as yarn breakage.

Abstract: PURPOSE:To prolong the service life of mold and at the same time reduce the energy required for mold clamping by a method wherein mold clamping pressures in primary molding and in secondary molding are respectively set to the pressures corresponding to the projected areas and effective injection forces of two cavities formed in the mold. CONSTITUTION:Multi-color molding is performed as follows: firstly, a core 13 s advanced hydraulically and shifted at high speed in order to clamp mold. After that, primary mold clamping pressure is applied to the mold. The set value of the primary mold clamping pressure is applied to the mold.

After the primary mold clamping pressure is applied to the mold 1 by a mold clamping cylinder 5, resin is injected from an injection cylinder 17 and filled in a cavity 9 in order to obtain a primary molded part. Next, the core 13 is retreated by actuating a hydraulic cylinder 14 so as to form a cavity at the center of the primary molded part. After that, the set pressure switch 23 changes over the mold clamping pressure from the primary mold clamping pressure to secondary mold clamping pressure and the mold clamping pressure is increased to the secondary mold clamping pressure through actuation of the pressure control valve 25.

Abstract: PURPOSE:To freely change the twisted angle of a twisted groove and to reduce the manhour by setting a rotary die into the inside of a through hole of a fixed die and extruding a billet as the rotary die is rotated. CONSTITUTION:The rotary die 10 is rotated by the actuation of a motor 15 and the rotational speed is controlled by the command of a controller 18.
