Filed: 1993-12-16
Abstract: PURPOSE: To reduce optimum power consumption by providing a programmable logic array and supplying electric power to only a part which includes a product termline in an active state for its operation. CONSTITUTION: An input signal is inputted to the array by only one input line X1 and pairs 9 to 12 of p type and n type devices are provided.

Title: Outlet of air conditioner embedded in ceiling
Inventor: KAWAI HIDENAO
IPC: F24F13/20
Filed: 1993-12-16
Abstract: PURPOSE:To clear from the supply of air a current flowing in contact with the ceiling sideways and keep the supply from impinging upon the occupant by designing the outlet in a manner in which its inside surface on the outer side in a longitudinal section is formed in a plane down to the lower end forming an edge and with an inclination making a prescribed actuate angle to a horizontal plane. CONSTITUTION:The outer-side edge surface 4a of an outlet 4 is composed of a plane surface 4d having its lower end at Point A, a plane surface 4b forming the uppermost part, and a cylindrical surface 4c which is between the surface 4d and 4b and joins the two plane surfaces and is designed to lessen the resistance to the flow of air. The plane surface 4d and an outside surface 8a having an edge close to a ceiling panel 8 meet at Point A and form an adge. In a horizontal blowout the current of air blown out separates at the lowermost end Point A of the outlet 4 and, also guided by the plane surface 4d at the end of the outlet 4, in part spreads obliquely downward with deceleration in velocity of the flow. As a result, the air flowing close to the ceiling is reduced in amount. Therefore, the ceiling keeps clean and, since the downward flow slows down in velocity, the occupant becomes less sensitive to the presence of a draft.

IPC: B23K101/04
Filed: 1996-11-13
Abstract: PROBLEM TO BE SOLVED: To improve joining strength and air-tightness by abutting a joining member on the one end of a tubular member, interposing a low m.p. alloy in the joining range, and then impressing an ultrasonic vibration to the alloy. SOLUTION: Firstly, the solid cylindrical joining member 3 is inserted into the tubular member 1 (A). In this case, by making the inner diameter of the member 1 almost equal to the outer diameter of the member 1, both members are in contact with each other with the large pressure in the jointed range 5 and the mechanical joining strength thereof becomes high. Successively, the integral member 1 and member 3 are preheated. The preheating temp. is made higher by about 50 deg.C than the m.p. of zinc alloy solder 7 in the case of using the zinc alloy solder 7, for example. Then, after the molten solder 7 is allowed to flow into the inner part of the member 1 (B), an ultrasonic horn 9 is abutted on the upper part of the member 1 and the ultrasonic vibration is impressed (C). By this method, the vicinity of boundary among the member 1, member 3 and the solder 7 is alloyed (D).  When the solder 7 is solidified and stabilized, the through-hole 11 is formed along the center axis (E).
