Title: Semiconductor device
Inventor: YASUKAWA AKIO
IPC: H05K1/02
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To reduce the strain in a bonded solder layer to avoid the fatigue breakdown of the solder layer by forming recesses at a part of a base underlying a semiconductor chip. SOLUTION: A plurality of semiconductor chips 1 are bonded with a solder layer 3 on an insulation substrate 2 bonded with a solder layer 5 on a base 4 with recesses 4a provided on the opposite surface of the base 4 to parts to which the semiconductor chips 1 are bonded and an intermediate plate 7 is bonded to the base 4 through a braze so as to cover the recesses 4a. Heat generated from the chips 2 at operating escapes via the base beneath the chips 12 to a cooling liq. 11, resulting in a temp. rise of the base 4 underlying the chips 1, but because of the recesses 4a formed at the base 4, temp. is distributed in the base 4 such that a thin wall part 4b is at a higher temp. and a thick wall part 4c at a lower temp., and if the thin wall part 4b is going to expand, the surrounding lower temp. thick wall part 4c restricts the expansion.  Thus a high strain is never exerted on the solder layer 3 on the thick wall part 4b and the fatigue breakdown can be avoided.

Abstract: PURPOSE:To synthesize a microcapsule capable of being cured by light with higher sensitivity by using an ionic surfactant to prepare an O/W type emulsion. CONSTITUTION:In a porous microcapsule synthesizing process, an ionic surfactant such as a styrene-maleic anhydride copolymer is used at the time of the preparation of an O/W type emulsion being the original form of a microcapsule. At first, an encapsulating solution containing a polymerizable monomer having two or more ethylenic unsaturated groups in its molecule and a photopolymerization initiator such as quinone is prepared. Separately, an ionic surfactant solution is prepared to be mixed with the encapsulating solution to be diffused therein to prepare a stable O/W type emulsion. The capsule film constituting monomer is formed into droplets while the emulsion is stirred to prepare a porous microcapsule dispersion. Next, a porous microcapsule is separated by centrifugal separation and irradiated with light to be cured.

IPC: F25J3/08
Filed: 1991-06-19
Abstract: PURPOSE:To improve regeneration conditions of an adsorption tower, to decrease the required quantity of an adsorbent and to miniaturize the adsorbing tower by incorporating a preregeneration process using excess waste gas discharging to the atmosphere before a regeneration process in an adsorption tower changeover process. CONSTITUTION:After the greater part of waste gas is fed as regeneration gas for an adsorption tower 4 during the regeneration process through a regeneration gas inlet valve 19 to the adsorption tower 4 where moisture and carbon dioxide are adsorbed, it is discharged through a regeneration gas outlet valve 22 to the atmosphere. Here before a regeneration process, a preregeneration process is performed. The preregeneration is being previously regenerated extra by making flow excess waste gas discharged to the atmosphere when in the depressurized and pressurized states only for the time obtained by shortening the depressurization and pressurization time. That is to say, the depressurization and pressurization time in the adsorption tower changeover process is shortened to the utmost, causing the preregeneration time to be secured. And during the preregeneration, a discharge valve 29 discharging the excess waste gas is fully opened and the whole waste gas is used as regeneration gas and preregeneration gas.

Title: Toilet cover, tank, and assembly
Inventor: TSUBOI HIROYUKI
IPC: G01N1/00
Filed: 1995-05-23
Abstract: PURPOSE: To replenish a carrier liquid while visually monitoring the content in a tank by checking the content in the tank while a toilet cover is erected. CONSTITUTION: A toilet cover 44 is fitted to a housing 18 so that the cover can be rotated. A carrier liquid tank 46 is mounted to the toilet cover 44, thus constituting a toilet edge assembly 48. The tank 46 holds a carrier liquid for carrying a urine sample to a measurement unit. The tank 46 is flat so that it is housed inside the toilet cover 44 and is formed by a transparent or semi- transparent material for a user to check the remainder of the carrier liquid. A liquid-replenishment port 54 is formed at the upper portion of the tank 46 so that it can be closed by a cap 56 with a screw. In the case of analyzing urine, the toilet cover 44 is rebounded along with the tank 46. The tank 46 is located at a higher position than a syringe pump, so a liquid pressure is operated, thus preventing air bubbles from being taken in the suction process.  Also, the pressure in the tank 46 reaches atmospheric pressure due to the overflow port at the neck of the tank 46, thus enabling liquid to flow smoothly.
