Title: Lead frame for semiconductor device
Inventor: FUKUTOME KATSUYUKI
IPC: H01L23/50
Filed: 1989-11-01
Abstract: PURPOSE:To obtain a lead frame for a semiconductor device for obtaining an equivalent effect to bending machining accurately even if the shape is in a complex pattern by forming a stage part and a lead terminal part independently and by superposing them. CONSTITUTION:A stage part 1 and a lead part 2 can be formed independently respectively. Then, by combining a frame 1 with the stage part only and a frame 2 with a lead part only and by superposing the frame 2 with the lead part only onto the frame 1 with the stage part only, one lead frame can be formed. Thus, since two frames are superposed, a stage difference occurs at the stage part 1 and the lead part 2, thus achieving an effect which is equivalent to bending machining which has been executed conventionally. Also, by changing the plate thickness of the frame 2 of the lead part only, the amount of stage difference between the stage part 1 and the lead part 2 can be changed simply.

CONSTITUTION:Both in case of a passenger riding out from a cage to a floor station 1 and in case of a passenger riding in a cage from the floor station 1, it is set that when the passenger goes up in a elevator to an upper floor, the passenger walks on the right side and when a passenger goes down in an elevator, the passenger walks on the left side. By setting a rule in a manner described above, at the floor station 1, a passenger 8 presses a floor station call 5U so that he goes up and the passenger waits on the right side of a floor station door 2. Meanwhile, a passenger 7 in a cage 6 rides at the part on the right side of the cage 6 since he goes up in an elevator. Thus, when the cage 6 stops at a given floor, a waiting passenger 8 rides in the cage 6 as shown by an outbound passage 10, and the passenger 7 rides out to the floor station 1 as shown by an inbound passage 9. Therefore, the waiting passenger 8 and the passenger 7 can smoothly ride in and out without collision with each other.

Title: Beam current measuring equipment
Inventor: MATSUZAKI TOMIO
IPC: C30B31/22
Filed: 1985-12-20
Abstract: PURPOSE:To accurately measure the beam current in an ion implantation device by providing a hole element in the slit of a paramagnetic material. CONSTITUTION:The detection of the beam current of an ion beam is made with standing a floody flag 6. If the ion beam is irradiated, a magnetic field is generated by the beam current and magnetic flux is applied to a hole element 12 via a paramagnetic material but the magnetic force applied to the (z) direction against the hole element 12 is different according to the beam current value of the ion beam 4. That is, the density of the magnetic flux applied to the hole element 12 is proportional to the beam current value. On the other hand, since the magnetic field is applied in the (z) direction to the hole element 12 and a direct current is applied in the (x) direction, hole voltage is generated in the (y) direction of the hole element 12. Since the hole voltage of the hole element 12 is proportional to the beam current of the ion beam 4, the beam current of the ion beam 4 can be measured indirectly by measuring the hole voltage of the hole element 12.

Abstract: PURPOSE:To enable charring to be easily conducted at desired places even by inexperienced persons, by providing grooves in the gap of a kiln body provided with freely openable upper and lower lids and on the outer periphery of an intake vent and sealing the inside of the kiln body with water. CONSTITUTION:A ceiling lid 2 provided with a chimney 3 having a chimney lid 4 which is freely openable by remote control is provided freely openably at the upper part of a cylindrical kiln body 1 made of a steel sheet. A groove of which the inner bank is higher than the other side is provided on that part of the kiln body 1, against which the lid 2 is abutted. Water is filled in the groove to form a water seal structure through which air and smoke cannot escape. An intake vent 5 is provided at the lower part of the body 1. A similar water seal structure is provided on that part of the vent 5, against which a freely openable lower lid 6 is abutted. Further, a water-sealed firing port 7 is provided to form a water-sealed charcoal kiln. The ceiling lid 2 is opened upward with a hydraulic device or by hand.

When the fire sufficiently spreads, the lid is closed and water sealing is performed. A small amount of air is introduced through the intake vent 5 to promote carbonization. When smoke turns bluish and semitransparent, the lid 4 is closed and the lid 6 is sealed with water to form a sealing state. After the completion of charring, charcoal is taken out of the lid 6.

Title: Pattern formation
Inventor: SHIYUREEGERU REO
IPC: G03F7/26
Filed: 1991-11-01
Abstract: PURPOSE:To form negative resist patterns of a high resolution by using an i-ray reduction stepper and to decrease the effect of standing waves. CONSTITUTION:A resist coating film consisting of an m,p-cresol novolak resin, 3,3'-dimethoxy-4,4'-diazide biphenyl, and naphthoquinone diazide sulfonate is exposed with patterns by light, such as i-ray (365nm) shorter in wavelength than 366nm and is then subjected to full-surface exposing by light, such as g-ray (436nm) of the wavelength longer than 400nm then to a baking treatment. The difference in the dissolution rate between the part exposed with the i-ray and the unexposed part increases to the difference larger than a resist which does not contain the naphthoquinone diazide sulfonate. The patterns of a high resolution are thus formed by using the reduction stepper of the short wavelength light, such as the i-ray.
