Title: Solder connecting method for fine pitch pads to component leads
Inventor: FUKUNAGA TAKAO
IPC: H05K3/34
Filed: 1992-10-15
Abstract: PURPOSE:To improve an external appearance and to improve connecting reliability by using lead-rich precoating solder as to obtain a desired solder alloy composition resulting from fusion with tin and tin alloy plated on component leads. CONSTITUTION:In order to form solder for finally connecting component leads to pads to alloy composition (normally eutectic alloy) as a target, it is effective to use lead-rich precoating solder on the pad. The lead content in the solder is decided by considering sizes of component leads 1 and pads 2 and plated thickness of the leads. Thus, a quantity of a plating material of the lead and a quantity of the precoating solder are obtained. The composition of the precoating solder is so decided that the final connecting solder becomes a desired composition. When a substitution of organic acid lead salt with tine is utilized. even if the composition of the precoating solder is made constant, the composition of the final connecting solder can be controlled.

Title: Image forming device
Inventor: ASHIBE TSUNENORI
IPC: G03G15/16
Filed: 1994-12-06
Abstract: PURPOSE: To prevent irregularities from occurring when toner is moved and to enhance transfer efficiency by restricting the sum of the surface roughness of a first image carrier and the surface roughness of an intermediate transfer body to be equal to or under a prescribed value. CONSTITUTION: The sum of the surface roughness Rmax of the first image carrier 71 and the surface roughness Rmax of the intermediate transfer body 72 is set to be <=20μm. That means, a distance that the toner 73 is moved to the transfer body 72 from the surface of a photoreceptive drum being the first image carrier 71 becomes short by reducing the sum of the surface roughness Rmax 74 of the first image carrier 71 and the surface roughness Rmax 75 of the transfer body 72. As the result, since the toner 73 can be linearly moved, the irregularities in an image is reduced. Besides, the detaching property of the toner 73 is increased and the transfer efficiency is enhanced because the distance that the toner 73 is moved to the transfer body 72 from the surface of the photoreceptive drum being the first image carrier 71 becomes short.

Title: Treating apparatus for gaseous radioactive waste
Inventor: MARUKI SHINICHIRO
IPC: G21F9/02
Filed: 1989-11-22
Abstract: PURPOSE:To reduce the load of steam and cooling water by heating the interior of an exhaust gas preheater by the steam-containing exhaust gas flowing out of an exhaust gas recombiner. CONSTITUTION:The exhaust gas extracted from a main condenser 2 by a steam extractor 3 is preheated by an exhaust gas preheater 4 and the bonding reaction of hydrogen and oxygen is performed in an exhaust gas recombiner 5 to form steam. At this time, the exhaust gas is heated to high temp. by heat of reaction and the temp. of the exhaust gas at an outlet becomes about 400 deg.C and the flow rate thereof becomes about 5,000kg/h. This high temp. exhaust gas is returned to the preheater 4 from an outlet pipe 5b to be utilized as a heating source. That is, since the exchange amount of heat necessary in the heating up to about 160 deg.C can be sufficiently supplied, a heated steam supply apparatus can be eliminated. Next, an exhaust gas condenser condenses the steam in the exhaust gas by the cooling water from a cooling water supply apparatus 7 but, since the exhaust gas cooled by the heat exchange of the preheater 4 flows in the condenser 6, the load of the apparatus 7 is reduced.

IPC: G01P5/00
Filed: 1990-11-07
Abstract: PURPOSE:To obtain an air current measuring device which may be used in a narrow space and which can be readily assembled, by measuring a bend of an optical path which caused by a variation in refractive index produced by a difference between densities. CONSTITUTION:Two branches of an optical fiber enter into a low temperature container 40 so that light is emitted from their light emitting ports 14A, 14B toward photodiode arrays 15A, 15B. Two light beams 11A, 11B cross an air stream jetted from an orifice nozzle 8. When the air current is produced, the refractive index varies due to a difference between densities so that the optical paths of the light beams 11A, 11B are bent, and accordingly, the light receiving points on the photodiode arrays 15A, 15B are shifted, that is, different diodes 18 receive light. The velocity (v) of the air current can be obtained by v = L/ t, where  t is a different obtained when the air current generates which is detected by the photodiode arrays 15A, 15B, and L is the distance between the photodiode arrays 15A, 15B.

Abstract: PURPOSE: To stop dissociation of a holding ring from a glass pot by fitting in the grooved wall of a holding ring covering the upper edge of the glass pot, a flange ring which engage the bead edge section of the glass pot from below. CONSTITUTION: A groove 4 formed in a holding ring 3 is injected with plastics after the coupling of a glass pot 1 to the holding ring 3 and forms a ring 8 after solidification. Additionally, the holding ring 3 is advantageously secured to the glass pot 1 by an annular flange ring 9.

Title: Static semiconductor memory and its test method
Inventor: KAWAMURA HIDEYOSHI
IPC: G01R31/28
Filed: 1996-11-14
Abstract: PROBLEM TO BE SOLVED: To reduce a cost for testing. SOLUTION: When a potential of a node N1 is made a 'H' level at the time of performing a test. Therefore, voltage to which power source voltage from a power source 41 is dropped by a drop circuit 81 is given to a power source voltage supplying line PL2 at the time of performing a test. On the other hand, a potential of a node N1 is made a 'L' level at the time of normally using. In this case, power source voltage from the power source 41 is given to the power source voltage supplying line PL2. The power source voltage supplying line PL2 is connected to a load element of a memory cell, at the time of performing a test, voltage given to the load element of the memory cell is smaller than that at the time of normally using. Therefore, a potential difference between two storage nodes of the memory cell can be made smaller than that at the time of normally using.  Therefore, the same state as a state in which a SRAM is placed under low temperature environment can be realized.
