Title: Air sucker
Inventor: FUKAO TAKAHISA
IPC: D01D11/00
Filed: 1986-05-23
Abstract: PURPOSE:To carry out the take-off operation of a yarn line smoothly and stably by providing a sucking port on the lower course part of an air sucker, in a yarn-line transferring air sucker. CONSTITUTION:A yarn 3 is taken off by the sucking force of a gas stream 4 which is fed into an air sucker 1 from a gas introducing port 2 and deposited in a container 8 and, in this case, the main part of the fed gas stream 4 is forcedly sucked out of the air sucked 1 through a gas sucking port 6 which is partitioned separately from the send-out port 5 of the yarn 3 by a partition board 7, by means of a suction pump, etc. and removed. Thereby, a gas stream 4' which is jetted out together with the yarn 3 is greatly reduced, preventing the entanglement of the yarn line 3 or the end breakage of fuzzing of the yarn 3 deposited in the container 8. Thereby, the take-off operation of a yarn line can be stably carried out.

IPC: H01L29/43
Filed: 1989-05-15
Abstract: PURPOSE:To enable the reduction in interlaminar diffusion between Si and Al by a method wherein Al-Cu and TiN are combined to use. CONSTITUTION:An upper Al-Cu layer 11 and a lower TiN layer 12 are deposited on a contac..t hole 13 formed inside an insulating layer 14 on a silicon substrate 15 of a semiconductor device to constitute an electrode wiring structure of this design. Aluminum alloy low in eutectic melting point or Al-Cu is used, whereby the temperature of a wafer stage required for reflow sputtering can be made low and the temperature-dependent diffusion of Si into an Al-Cu layer can be reduced. TiN is able to more efficiently prevent Al from diffusing.

Only the microcapsules including a bonding agent or together with those including a hardening agent are dispersed in the plating soln. and are floated. Then the dispersion is electrolyzed with a metal or an alloy as a cathode to form a eutectoid of the capsules to a thickness of the eutectiod not smaller than 30% the diameter of the capsules. The foil made by the method is placed on the base material such as wood with the capsule-eutectic side faced to the base material, and is thermocompressed from both sides so as to break the capsules, so that the bonding agent and the hardening agent wet the interface, and the foil and the base material are bonded strongly by hardening reaction.

Filed: 1989-05-15
Abstract: PURPOSE:To make it possible to absorb a connection error by a method wherein, pertaining to the pattern containing a stage shifting error, a pattern is draw on the adjacently located main fields which contain the above-mentioned pattern, and an overlap drawing is conducted. CONSTITUTION:When a pattern is drawn on the left main field, the pattern 6 in this region and the pattern 4 stretching over a connection part are drawn by deflection without cutting the pattern. Then, when a patterning is conducted on a main field 2b, a capacitor 7 in this region and a pattern stretching over a connection part are drawn by deflection cutting the pattern. However, the patterns 6 and 7 in respective region are drawn using a proper dosage A, and the pattern 4 stretching over a connection part is drawn using a 1/2A dosage. As a result, an apparent connection deviation is not generated even when there is a connection error of 0.1mum, and the accuracy of pattern can be improved.

Title: Semiconductor device
Inventor: AKABANE KATSUMI
IPC: H01L23/04
Filed: 1981-07-31
Abstract: PURPOSE:To fix elements thermal electrically with good conductivity and high accuracy, by contacting the arc surface of a fixed ring  and the inside wall of an arbitrary shaped surface continuous to the arc surface with the outer boundary of an element and circumscribing the inside wall of the open hole in an actual circle of a flange part with an electrode in an actual circle of section. CONSTITUTION:The inside wall 17aa of a cylindrical part 17a of the fixed ring is constituted of an arc surface and a flat surface continuous thereto and forms a passage which is electrically and thermally good when fitting the fixed ring 17 and the lower electrode 4 on an actual circular surface and using a metallic ring. The fixed ring 17 and an anode electrode plate 11 are fixed as conventional. In this constitution, the decrease in positioning accuracy based on processing accuracy generates only between the ring 17 and the electrode plate 11. Now, since the inside wall 17ba of the flange 17b and the section of the lower electrode 4 are formed in a true roundness, the positioning accuracy is high, and the contact area with the electrode plate 11 has defect parts. Therefore, electrically and thermally excellent conduction is performed.

Abstract: PROBLEM TO BE SOLVED: To enable highly accurate measurement of the run-out of a gear in a short time with an elective utilization of a computer aided numerical control type gear measuring apparatus by a method wherein the pitch of each tooth of a gear is measured to determine a pitch error from a theoretical value and the run-out of the teeth is calculated from the pitch errors at diagonal positions. SOLUTION: A measuring element 14 of a detector 13 is inserted into a tooth space of a gear 1 to be measured such as hypoid gear and the tip thereof is set on a pitch circle. The gear 1 is rotated by a spindle 11 and when a set pressure is detected by a differential transformer 15, the rotation of the gear 1 is stopped and an angle of rotation is read out by a rotary encoder 16. Then, the measuring element 14 is retracted from the gear space of the gear 1 and the gear 1 is turned by a specified angle to be set at the same position of the tooth space of the subsequent gear. The angle of rotation is read out by the same method.  In this manner, an angle of rotation is measured for all tooth spaces to be inputted into a computer of a computer aided numerical control type gear measuring apparatus and a pitch error of each tooth is determined based on the angle of rotation measured and an ideal pitch previously identified from design specifications of the gear 1.

Title: Vibration support transfer device of packing bag in measuring and packing machine
Inventor: MASUDA SUSUMU
IPC: B65B29/00
Filed: 1994-04-21
Abstract: PURPOSE:To uniformize bulky tea charmed in a bad and cope with any of various sizes of bags to be placed, by fitting a vibration means on a support base of packing bags in a measuring and packing machine and freely adjust the height of support base in accordance with the size of bags to be placed. CONSTITUTION:When a large bag is used, two cylinders 5, 6 having different strokes from each other, installed between guide rods 4, 4 are connected to each other by mutual piston rods. When the cylinders 5, 6 are actuated respectively, the piston rods of respective cylinders 5, 6 are stretched to the maximum length and the support base 14 of the bad is set at the highest position (a). In this way, since the setting position of the support base of bag can be set at a required level, it is not necessary to adjust the position of the bag opening- holder of the automatic measuring and bagging machine and even only simple operation of switches is enough. Tea is charged into bags from an automatic measuring and bagging machine while vibrating the support base of the bag by means of an eccentric cam. Accordingly, a bulky material can be charged in the most appropriate way.

Title: Ac variable speed device of dc bus type
Inventor: NISHI YOSHIO
IPC: H02P5/74
Filed: 1983-06-29
Abstract: PURPOSE:To suppress the variation in a DC bus voltage to the minimum limit by applying a signal proportional to the current of a DC bus to an input circuit of a voltage controller of a converter as an operating mode switching acceleration signal when shifting to an operating mode. CONSTITUTION:When the part of induction motors which are operated at the aligned speed are shifted to a regenerator operation, a DC bus voltage Vd starts rising, a power drive generative conversion detector 11 outputs to close a switch 12. Accordingly, an operating mode conversion acceleration signal P is applied in the same polarity as the output of a DC voltage detector 7 to a butting point 0. Thus, since the input of a voltage controller 9 becomes a large regenerative command input, a converter 2 rapidly shifts to the regenerative operation, the rise of the DC bus voltage Vdc is suppressed, and the variation in the speeds of induction motor IM group which are not operated at the aligned speed.
