Title: Socket for semiconductor device
Inventor: KURATA MASARU
IPC: H01R33/76
Filed: 1982-06-19
Abstract: PURPOSE:To obtain a rigid socket for semiconductor element by integrally housing socket hole, external connecting terminal and internal conductive material within a box. CONSTITUTION:D is a box body forming a socket device and the box body itself may be a solid box body or a hollow box body. The box body D is rectangular provided with two lines of a plurality of socket holes 1 at the upper surface and the extruded external connecting terminal 3 at the lower surface. The socket hole 1 is engaged with the terminal of shrink type semiconductor element. Although not indicated, a conductive material is provided within the box body D as a material for electrically connecting between each socket hole 1 and corresponding external connecting terminal 3. This conductive material may be a printed circuit. Since the box body D integrally comprises the socket hole 1, external connecting terminal and internal conductive material connecting them, any clearance is not generated even in case of loading or unloading semiconductor elements to/from the socket hole 1, the device as a whole becomes very rigid. Moreover, since a printed circuit board B is not required, realizing cost can be lowered.

Title: Fluorinated polyamic acid, fluorinated polyimide, and their production
Inventor: SASAKI SHIGEKUNI
IPC: G02B6/12
Filed: 1991-04-12
Abstract: PURPOSE:To produce a fluorinated polyimide which is heat-resistant enough for producing an optoelectronic integrated circuit and suffers only a small loss in light tranmission in the nearinfrared region by cyclizing a specific fluorinated polyamic acid. CONSTITUTION:A fluorinated polyimide having repeating units of formula III is produced by reacting an acid dianhydride of formula I, a tetracarboxylic acid thereof, or a reactive deriv. thereof with an org. diamine of formula II (wherein R is a divalent org. group having at least one hydrogen atom) and cyclizing the resulting polyamic acid. Since all the monovalent atoms bonded to the carbon atoms of the phenyl rings of the acid dianhydride units in the polyimide are fluorine and the polyimide has no C-H bond in the molecule, the vibration absorption due to the C-H bond, the biggest cause of loss in light transmission, in the nearinfrared region is decreased.

Abstract: PURPOSE:To provide a sugar source capable of selectively proliferating bifidus bacteria, and composed of kumicose or naminose. CONSTITUTION:A sugar source composed of Galalpha1-2betaFru(kumicose) or Gacalpha1- 2beta-Fru6-2betaFru(naminose). Kumicose can be prepared by treating a solution containing galactose and sucrose with levan-sucrase originated from Bacillus subtilis, at 25-37 deg.C and 3.5-7.5pH, especially about 30 deg.C and about 6pH, and naminose is obtained by the similar process using a solution of sucrose only. Kumicose and naminose can be used as it is, or in combination with bifidus bacteria, as an intestinal function controlling agent effective to diarrhea and constipation or an agent to lower the ammonia level in blood. In addition to the above use, it can be used as a low-calorific food because it has slight sweetness and is hardly absorbable by the body.

Title: Heating equipment for liquid
Inventor: MARUYAMA NOBORU
IPC: F23J11/00
Filed: 1992-04-27
Abstract: PURPOSE:To prevent unstableness of the state of combustion due to intrusion of disturbance and generation of noise by a construction wherein a smoke gathering chamber having a larger sectional area than an exhaust port is provided below the exhaust port. CONSTITUTION:A smoke gathering chamber 14 having a larger sectional area than a discharge port 10 is provided below the discharge port 10. A combustion gas ascending inside a combustion chamber 9 turns round in the upper part of the chamber and descends through a combustion gas descent chamber 3, supplying heat to a liquid in inner and outer water chambers 7 and 6. Thereby incomplete combustion is prevented and also the temperature of the liquid is raised with the heat exchanger effectiveness of the combustion gas and the liquid increased. The flow velocity of the combustion gas descending in this way, passing the discharge port 10 at a high speed and being discharged into the smoke gathering chamber 14 becomes small, since the area of the smoke gathering chamber 14 is larger than that of the exhaust port 10, and a discharge pressure is maintained for the discharge port 10. When disturbance from an exhaust port of an exhaust tube 13 intrudes into the smoke gathering chamber 14, on the other hand, the flow velocity thereof lowers and the disturbance is dispersed and becomes weak.

Title: Equipment for truing up iron sheets
Inventor: KATOU NOBORU
IPC: B65G57/11
Filed: 1981-07-13
Abstract: PURPOSE:To automatically take out, true up and stack thin iron sheets intermittently brought by a conveyor or the like. CONSTITUTION:When an iron sheet 26b brought by a conveyor 2 has come into contact with a detector 20, an air cylinder 16 acts to displace a stop plate 15 to its vertical position so that the front end of the iron sheet collides against the stop plate. As a result, the posture of the iron sheet is controlled. Because of the action of a timer, the air cylinder 16 acts again in the opposite direction to return the stop plate 15 to its horizontal position so that the iron sheet 26b having been blocked resumes moving forth. The speed of the iron sheet 26b is increased by a magnet roller 3 so that the iron sheet slightly overreaches a preset longitudinal true-up reference plate 22 and lateral true-up reference plates 24. After that, a pusher 23 acts to finally correct the iron sheet 26c from the overreach position to a regular position. Such operation is repeated to stack iron sheets.
