IPC: H01F27/26
Filed: 1988-06-10
Abstract: PURPOSE:To enable a transformer with improved mass-productivity and quality to be obtained by caulking a laminated steel plate holding a caulking part and by welding it. CONSTITUTION:A prescribed number of E core steel plates 4a are laminated and are caulked by a rivet 10a to form a E core 4. A prescribed number of I core steel plates 7a are laminated and are caulked by the rivet 10a to form an I core 7. A bobbin 1 is inserted int o an E core 4, and I core 7 is placed on the E core 4, and a welding part 8 is welded. Since the E core 4 is fixed by a caulking part 10, the bobbin 1 can be inserted easily. Also, since the I core 7 shape is fixed by the caulking part 10, it is not necessary to support it until welding ends. It allows a transformer with improved productivity and a stable quality to be obtained.

Title: Circular saw having cemented carbide cutter
Inventor: MASUDA HIROHIKO
IPC: B23D61/02
Filed: 1988-06-13
Abstract: PURPOSE:To dissolve stress concentration without reducing the strength of a substrate by carrying out polishing after forming a linear impression in the radial direction between the tips of a disc-shaped substrate made of steel on the outer periphery of which a plurality of superhard tips are soldered. CONSTITUTION:When a circular saw cutter is soldered, a cemented carbide tip 2, solder 3, and the steel of a substrate 1 are put into high temperature, and expanded with each characteristic thermal expansion rate, and in cooling, the stress concentration is generated at the soldered part on the basis of the difference of the thermal expansion rate, and a tip 2 having the smallest thermal expansion rate is applied with a pulling force. The stress concentration can be dissolved by forming an impression 5. Therefore, no warp due to stress concentration is generated on the circular saw cutter, and also the tip 2 is not applied with a pulling force due to the stress concentration, and the superior polishing is permitted. Further, though the tip 2 possesses a high resistance force for a compression force, the tip 2 possesses weak property for a pulling force. Therefore, when polishing is performed in the stress concentration state, a crack is generated on the tip 2 applied with pulling action, but the polishing free from crack is permitted because polishing is carried out after the stress concentration is dissolved by the impression 5.

Abstract: PROBLEM TO BE SOLVED: To form a high quality image wherein pitch variation is suppressed irrespective of variation of a rotation speed of a photosensitive body by a method wherein variation condition of the rotation speed of the photosensitive body is detected and an emission time period of an LED device is adjusted based on the detected result. SOLUTION: An output pulse from a photodetector of a sensor section 201 is inputted to a counter 203 and memory means 204, 205 and a pulse of which frequency is sufficiently higher than the received pulse is generated by a reference signal generating means 202. The counter 203 counts the number of times that the reference signal pulses are inputted for one time of the received pulse and outputs the value as a rotation speed of a photosensitive drum 11 at a present time. The rotation speed of the photosensitive drum 11 is predicted by means of an arithmetic unit 206 on the basis of one-time previous rotation speed data stored in the memory means 204 and two-time previous rotation speed data stored in the memory means 205 to be outputted as the number of reference signal pulses.  An emission time period of an LED array 210 is controlled to be adjusted by counting the number by means of the counter 207.
