Title: Solder bump
Inventor: SATO TOSHIHIKO
IPC: H05K3/34
Filed: 1987-05-09
Abstract: PURPOSE:To lengthen a connection line of a solder bump by specifying a content of tin in the lead-tin-alloy solder bump. CONSTITUTION:A connection life of a lead (Pb)-tin(Sn)-alloy solder bump has a tendency to become long as a content of Sn is decreased; when the content of Sn is less than 3 wt.%, the connection life becomes nearly constant long life. Due to this fact, the content x of Sn is set at 0<x<5 in order to lengthen the connection life. When the content is set at 0.5<=x<=4, it is possible to lengthen the connection life and to prevent a defective connection. Furthermore, when the content is set at 1<=x<=3, it is possible to lengthen the connection life furthermore and to more effectively prevent the defective connection.

Title: Piston for internal combustion engine
Inventor: KOIKE TOSHIKATSU
IPC: F02F3/00
Filed: 1991-04-19
Abstract: PURPOSE:To increase heat resisting strength of a piston by small suppressing thermal expansion of the piston for an internal combustion engine. CONSTITUTION:A piston 1 for an internal combustion engine is obtained by an Al alloy formed by containing 5 to 15wt.% Mg and further adding heat resisting low expansion grains of 10mum or less mean grain size. When added a suitable amount of the heat resisting low expansion grains such as an SiC grain of 10mum or less mean grain size, it is experimentally found out that a coefficient of thermal expansion can be suppressed to 24mu10<-6>/ deg.C or less(20 to 200 deg.C) even when a content of Mg is increased. Accordingly, even when heat resisting strength of the piston 1 is increased by increasing the content of Mg, a thermal expansion amount of the piston 1 can be small suppressed.

Title: Fresh article storage device
Inventor: TAKEDA JUN
IPC: A01F25/00
Filed: 1990-04-26
Abstract: PURPOSE:To contrive the reduction in the size of the device and the reduction in the price of the device by combining a storage chamber, carbonic acid gas- generating device, an adsorbing material, a passageway-switching member and a carbonic acid-adsorbing device so as to achieve a specific action. CONSTITUTION:A gas flowing in an adsorbing material 135 forms a layer flow because spaces 172' play the role of pressure chambers, thereby not causing the deterioration of the adsorption ability thereof. Even when the amount of circulated air is increased and the flow of the air is changed from the homogeneous layer flow state into a concentrated flow state, the adsorption ability of the adsorbing material is not deteriorated because the communication openings 168-170, 169 and 171 are disposed at positions giving the longest gas-passing distances of the adsorbing material, and the passing distance of the circulated gas can be shortened. The decrease in the amount of the circulated air due to the loss of pressure is thereby reduced and the required amount of the circulated air can be secured with a small air blower. Since pipings to be connected can be reduced and the container for receiving the adsorbing material can be simplified, the size of the device can be reduced and an inexpensive storage chamber can be obtained.

IPC: F25J3/04
Filed: 1997-05-01
Abstract: PROBLEM TO BE SOLVED: To utilize the owned capability of a main heat exchanger most effectively by utilizing a line at a lower temperature side than a compressed air blow-off position halfway from a position in a main heat exchanger as the passage line of a return gas. SOLUTION: In an air separation method, a compressed air being sent from a branch pipeline 6b being branched from a compressed air feeding pipeline 6a to the hightemperature side of a main heat exchanger 7 is extracted halfway through the main heat exchanger 7, is heat-insulated and inflated by an inflation turbine 5, is cooled to a cold temperature, and is sent to the upper part of a rectifying column. In this case, in the compressed air being sent to the main heat exchanger 7 through the branch pipeline 6b, only one portion of the high- temperature side is utilized for heat exchange so that it is not cooled excessively in the main heat exchanger 7 and the greater part of it is not utilized.  Furthermore, the cold air is collected in the main heat exchanger 7 most effectively when a return gas temperature is set to the lowest temperature region, thus utilizing the unused low-temperature side region in the main heat exchanger 7 effectively.

Title: Manufacture of image pickup tube
Inventor: HANABUSA TAKAOMI
IPC: H01J9/14
Filed: 1984-06-04
Abstract: PURPOSE:To improve the productionability by cutting into specific pattern through an oval laser beam having long axis in the circumferential direction thereby shortening the time necessary for cutting without degrading the deflection linearity. CONSTITUTION:The circumferential interval between each electrode H+-V- of electrode G4 is made approximately constant through cutting by means of an oval laser beam having long axis in circumferential direction. The width of gap at the portions in axial direction such as the portions a-b, c-d, e-f,... between the electrode G3 and the leads TH+-TV- are formed wide but the width of gap at the portions in circumferential direction such as b-c, d-e, f-g,... are formed narrow. Consequently, the laser beam is scanned more than two times on the circumferential portions to perform cutting thus to widen the gap. As a result, the deflection linearity will never degrade.
