Title: Laser device
Inventor: TAKAGI SHIGERU
IPC: H01S3/097
Filed: 1978-01-24
Abstract: PURPOSE:To lower the voltage to be applied to the variable impedance by connecting the electric value unit to the voltage point which is lower than the output voltage of the DC power supply unit, and thus to obtain a low-cost and high-reliability laser device. CONSTITUTION:DC power supply unit 11 comprises DC power source 5 and 10 connected in series in order to secure addition of the output voltage. At the same time, electric valve unit 1, 2, 3 and 7 are connected to the voltage point which is lower than the output voltage of unit 11 in order to prevent the high voltage from being applied to the variable impedance element at the instant when the variable impedance element such as transistor 4 or the like is opened. As a result, the voltage to be applied to the variable impedance element can be reduced, thus obtaining a low-cost and highly reliable laser device.

Title: Foreign matter separating-classifying method and device in grinding/polishing/cleaning material
Inventor: MASE KEIJI
IPC: B24C9/00
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To provide a method and device to easily and reliably remove a foreign matter simultaneously when a grinding/polishing/cleaning material is fed forward in the flowing direction of an air current without causing mesh-clogging in a net-like body in a process of feeding the grinding/polishing/cleaning material in which a foreign matter mixedly exists by carrying it on the air current. SOLUTION: A main body 11 is formed to pass an air current by communicating with an air current generating means, and a supply port 12 in which a grinding/polishing/cleaning material 21 flows is arranged in a lower part of the main body 11, and a discharge port 13 to discharge the grinding/polishing/cleaning material 21 is arranged in an upper part of the main body 11, and when the grinding/polishing/cleaning material 21 and an mixedly existing foreign matter 22 are fed to the main body 11 from the supply port 12 by carrying them on an air current, an ascending current is generated in the main body 11, and the grinding/polishing/cleaning material 21 and the foreign matter 22 ascend together with the ascending current. Since the inside of the main body 11 is separately arranged by partitioning the main body 11 into an upper part and a lower part by a net-like body 16 formed of meshes capable of passing the grinding/polishing/cleaning material 21, the ascending current passes through the net-like body 16. At this time, the grinding/polishing/cleaning material 21 passes through the net-like body 16 together with the ascending current, and is discharged from the discharge port 13, but the foreign matter 22 falls by dead weight since its passing is checked by the net-like body 16, and the foreign matter 22 is easily and reliably removed from inside the grinding/polishing/cleaning material.

Abstract: PURPOSE:To eliminate a residual stress of a bending part by absorbing a horizontal component applied to a lead at the time of blanking, and to prevent the generation of a torsion in the tip part of the lead, by pressing strongly the outside periphery of a blanking part of the vicinity of the tip of the lead, and on the other hand, and executing the blanking in a state that a pressing force of the base part is weakened or it is not pressed. CONSTITUTION:In case of blanking a lead frame 1 for a semiconductor device, to a prescribed pattern by a press, it is prevented that a torsion is generated in a tip part 2b being near a pad 3 of a lead 2 which has been blanked in case a bending part 2c exists in the lead 2. That is to say, at the time of blanking the lead 2, the outside periphery of the tip part 2b of the lead is pressed strongly and fixed, and it is blanked by pressing weakly the outside periphery of the blanking part of the bending part 2c being near the base part of the lead, or without pressing it at all. In such a way, a torsion of the tip part 2b of the lead is not generated, a shift in the horizontal direction is also deceased, and the product quality and the yield are improved.

Title: Door lock structure
Inventor: IMAI YUKIO
IPC: E05C1/06
Filed: 1990-01-16
Abstract: PURPOSE:To lock the opening angle of a door substantially at 90 degrees, and lock and unlock the door with ease by opening the door approx. at 90 degree, suspending a slider under the condition where a door frame member and a stopper plate are formed in parallel and inserting the stopper into a gap produced between the surface of the slider and the parallel sheet section of the stopper plate. CONSTITUTION:When a door is opened, an intersection angle between a door frame member 2B and a stopper plate 15 is reduced while a slider 20 approaches the stopper plate 15. As a result, a horizontal plate 34 makes a sliding motion on the upper end surface 16 of a hinge main body 10 so that a contact position of the bottom may move to a parallel plate side 33. When the door is opened at approx. 90 degree. the stopper plate 15 and the door frame member 2B are formed in parallel to each other. The horizontal plate 34 is positioned outside the stopper plate 15 while the bottom of the horizontal plate is deviated from the upper end surface of the stopper plate 15 so that the slider 20 may drop. Therefore, this creates a condition in which the stopper plate 15 of the hinge main body 10 is inserted into the gap produced between the slider 20 and a horizontal plate 33 of an engagement plate 30, which locks the door in an opened state approx. at 90 degree. When the door is closed, the slider 20 is pulled up by hand and the lock is released.
