Title: Resin sealing device for semiconductor element
Inventor: ARAKAWA ISAO
IPC: B29L31/34
Filed: 1985-07-22
Abstract: PURPOSE:To improve the efficiency of resin seal work largely by mounting a bonding member coupled with an upper platen and a lower platen, a moving platen, first and second bottom forces and first and second top forces. CONSTITUTION:In the process of lifting of a moving platen 13, a first top force 21 and a first bottom force 20 are separated largely, a second top force 23 and a second bottom force 22 are pressed, and a semiconductor element is sealed with a resin. On the other hand, the semiconductor element sealed with the resin in the same manner as a conventional method by the first top force 21 and the first bottom force 20 at the same time. When the resin is cured, the moving platen 13 is transferred to the process of lowering, and a large space is formed between the second top force 23 and the second bottom force 22 while the first top force 21 and the first bottom force 20 are transferred to the process of pressing. The semiconductor element is sealed with the resin by the first top force 21 and the second bottom force 20 while the semiconductor element to which a sealing process is completed by the second top force 23 and the second bottom force 22 is removed. That is, resin seal work is executed twice by the vertical operation of the moving platen 13.

Title: Dry type electrostatic precipitator
Inventor: IEMORI NOBUMASA
IPC: B03C3/88
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To prevent deposition of dust by arranging a gas jetting nozzle at a dust deposition position of a hopper for collecting the dust by a dust collection electrode at the lower part and jetting gas from the nozzle toward the dust collection position. SOLUTION: Process gas enters the inside of a casing 2 from the inlet. Since a discharge electrode electrifies powder particles in the process gas, the powder particles stick to the dust collection electrode and are separated from the process gas. The separated powder particles drop naturally or drop with a hammering work of a hammer machine, being collected in the hopper 5 as the dust 7, loaded on a conveyer and discharged from a dust discharge port. The nozzles 11, 12 periodically jet the gas 18 to a joint part of the hopper 5 or a corner part, and the dust 7 deposited on these parts are forcedly fallen down with a jetting stream. Thus, deposition and sticking of the dust 7 are prevented.

Title: Photomask
Inventor: HOSOYA AKIHIRO
IPC: G03F1/00
Filed: 1987-06-30
Abstract: PURPOSE:To red variance in the size of a formed pattern directly, visually, and accurately by providing a photomask with a fixed-form pattern group which is equal in width and interval and plural pattern groups which are varied in width and interval at a constant rate besides a semiconductor pattern. CONSTITUTION:The fixed-form pattern group 11 which is equal in width and interval and pattern groups 12-14 and 15-17 which are varied in pattern group width and interval are formed. It is assumed that when the pattern groups 11-17 are transferred to a photoresist film on a semiconductor substrate or insulating film on the semiconductor substrate, there is variance in pattern size caused by process variation. At this time, a part where the width and interval of the actual pattern become equal is confirmed by being checked visually through a microscope, etc., and the deviation to the part where the width and interval of the pattern are equal on a mask is measured. Consequently, the variance in pattern size is accurately read.

Inventor: EZAKI KUNIO
IPC: B61B13/06
Filed: 1993-06-08
Abstract: PURPOSE:To perform regularly stable carrying regardless of the inclination gradient of a track. CONSTITUTION:A frictional wheel 12 is connected to the driving shaft of a variable torque motor 11, and a pinion gear 13 is connected to the driving shaft through an elliptic gear. Therefore, the pinion gear 13 has an output torque larger than the frictional wheel 12. In a vertical traveling section having a large load, a self-advancing vehicle 2 is driven forward by the gearing of a driven gear with a rack 18 laid along a track 3. On the other hand, in a horizontal traveling section having a small load, the self-advancing vehicle 2 is driven forward by the contact of the frictional wheel 12 with a frictional surface 17 similarly laid along the track 3. Thus, stable carrying can be performed in compliance with the load fluctuating with a wider fluctuating width, compared with a conventional carrying device.

IPC: A61M5/32
Filed: 1988-06-30
Abstract: PURPOSE:To obtain a needle point blockade treatment device for a spent medical needle with the tip of a spent medical needle blockaded by electric discharge by providing the spot welding device in which a pair of plus and minus pressure welding pieces for electric discharge is oppositely provided so that the tip of the medical needle inserted into a casing can be nippedly pressed. CONSTITUTION:When the captioned device is used, a medical needle A is inserted from the small hole 1a of a casing 1 with a needle point a made ahead. This causes the said needle point a to be nippedly pressed with a pair of pressure welding pieces 2a and 2b for electric discharge. However the needle point a is uncrushed at this point of time. Then, when a switch circuit 7 is made switch-on for a short time by a manual operation, a required high voltage current flows to a plus pressure welding piece 2a from a pressure rise circuit 3 for a short time, electric discharge is made between the pieces 2a and 2b, and the needle point a is ignited for a short time. This causes the needle point a ignited to be crushed with the pieces 2a and 2b. Then the pieces 2a and 2b are opened with an actuator, the needle point a is released, and the needle A in which the needle point a is blockaded is took out in the outside of the casing 1.
