Title: Spiral spring
Inventor: HAYASHI SHINICHIRO
IPC: F16F1/10
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To avoid contact between plates at the time of winding, and provide similar torque curves at the time of winding and de-winding of a spiral spring which is used for a wind regulator for a motorcar by eccentrically arranging a winding center. SOLUTION: A winding center 2 of a spiral spring 1 is set an eccentric position. A space E1 between plates in a left large diameter side portion 1a is set wider than a space E2 between plates in a right small diameter side portion 1b across a linear line M therewith, the line passing an inner end 3 and an outer end 4. Expanded portions 5, 5a whose radius of curvatures are partially reduced are formed on a plural portions on an intermediate position of the spiral spring 1. Such a spiral spring 1 shows a large variation amount of the space E1 between plates at the large diameter side portion 1a and a small fluctuation amount of the space E2 between plates at the small diameter side portion 1b through total winding around a rotary shaft D. The space E1 and E2 are substantially equalized to the constant valve for preventing contact between the plates.

Title: Lead frame for ceramic package
Inventor: OKAZAWA HIDEYASU
IPC: H01L23/50
Filed: 1991-03-30
Abstract: PURPOSE:To enable a lead tip to be brazed positively within being removed from a brazing pad by allowing a lead tip of the lead frame to be brazed to a specified brazing pad while adjusting a difference in thermal expansion between the lead frame and a ceramic package. CONSTITUTION:A metal lead frame 10 and a ceramic package are aligned. In this case, distances A1, A2, A3,... between a reference line 15 connecting an alignment position of the lead frame 10 and that of each lead 12 and a tip of the brazing portion of each lead 12 are shorter than distances B1, B2, B3,... between the brazing pad corresponding to each of the lead 12 in the ceramic package and the reference line 15. However, adjustment of brazing position due to difference in thermal expansion between the ceramic package and the lead frame 10 at the brazing temperature can be achieved, thus achieving brazing without causing the lead tip from being removed from a specified brazing pad which is formed at the ceramic package.

Abstract: PURPOSE:To efficiently separate lubricant oil from coolang gas containing the former with no provision of an oil separator, by detouring coolant gas in a long distance with a compressor so that coolant gas is subjected to repetitions of impingement upon the wall of the compressor and frictional action. CONSTITUTION:Coolant gas which is sucked into pump chambers 9 during a suction stroke and is then discharged into discharge passages 21 on both sides of a cylinder 3a through discharge ports 19, respectively, during a discharge stroke, turns its direction when it impinges upon plate walls 21a, and therefore, flows into a front space through first communication passages 22 on both sides of the cylinder 3a. Then, after turning of its direction by impingement upon the front wall of a front head 1a, both streams of coolant gas flow along the inner periphery of the front space, merging together in the upper section of the front space, and flow into an intermediate space 16 through an upper second communication passage 23. Then, coolant gas flows from a third communication passage to a discharge port through a rear space and is finally fed into an external circuit. During the above-mentioned period lubricant oil contained in coolant gas is detoured in a long distance within the compressor so that lubricant oil is surely separated from the coolant due to repetitions of impingement against the wall of the compressor and due to friction with respect to the wall, and drops in the lower section of a casing.

Filed: 1995-04-20
Abstract: PURPOSE: To provide a stack device which can improve an execution speed. CONSTITUTION: This stack device has a RAM 3 which stores data, a selecting circuit 11 which selects one of a program counter(PC) output 2 and a RAM output 10 as input data to a RAM 3, and an output latch 15 which stores the output data of this selecting circuit 11. When the data are written in the RAM 3, the selecting circuit 11 selects the PC output 2 and stores the data even in the output latch 15. Further, when the data are read out of the RAM 3, the data is not read out of the RAM 3 directly, and the data stored in the output latch 15 are read out. Consequently, it becomes unnecessary to wait for access to the RAM 3 and the execution speed can be improved.
