Title: Device for detecting rotary displacement and linearly moving displacement
Inventor: MARUI TOMOTAKA
IPC: G01D5/36
Filed: 1981-09-30
Abstract: PURPOSE:To make it possible to improve reliability in detecting the displacement, by providing a part, wherein a light signal is coded by sequentially changing transmittance or the wavelength of transmitting light, on the periphery of a rotary disk, transmitting the lihgt signal through optical fiber, thereby removing the effects of temperature changes and electrical noises. CONSTITUTION:The light from a light source 51 reaches a coding part 71 of the rotary disk 70 through the optical fiber 52. The transmitted light reaches a photoelectric transducer 57 through the optical fiber 56. The coding part 71 is colored in such a way that the transparence gradually increases from a black painted part in the circumferential direction so that the transmittance is changed from the reference position monotonously and continuously. Since the amount of the transmitted light, i.e. output voltage, is gradually changed by the rotary angle, the device is resistant to the pulse noises. The rotary displacement is computed in a processing circuit 59 by using the detected signal. As a coding means, the transmittance can be changed stepwise, or a plurality of filters which can transmit the light beams having different colors can constitute the device.

Abstract: PURPOSE:To inhibit the generation of a resin flash, and to improve solder dipping properties by flattening and treating a lead frame through coining before chip bonding before a resin mold process and flatly correcting the surface, an edge of which is rounded by punching a lead. CONSTITUTION:A lead frame 15 manufactured from a metallic plate through punching molding is coining-treated before chip bonding. Consequently, the whole lead frame 15 is coined and flattened, and the roundness (sagging) of each section edge of the main surface of the lead frame 15 is removed. Since the lead frame 15 is coining-treated on molding, the surface and the rear are flattened. As a result, the surface and rear of the lead frame 15 are fast stuck to a bottom force 3 and a top force 4. Accordingly, the resin component of a resin 6 does not leak also to the surface and rear of a lead 1, thus generating no flash. Consequently, when solder dipping treatment is executed to the surface of the lead after the molding, trouble in which solder 10 is difficult to adhere on the surface of the lead, thus improving the yield of solder dipping.
