Title: Manufacture of semiconductor device
Inventor: AKIMOTO MASAO
IPC: H01L21/225
Filed: 1988-05-10
Abstract: PURPOSE:To seek to lower sheet resistance speedily by performing thermal diffusion in oxidizing gas whose flow rate is so set that an oxide film created at the interface between antimony glass layer and a semiconductor substrate may grow at a speed below the diffusion speed of antimony impurity by the control of supply rate. CONSTITUTION:When an antimony glass layer 3 is formed on a semiconductor substrate 1 and diffused in oxidizing gas, an oxide film is created at an interface between the antimony glass layer 3 and the semiconductor substrate 1, and the growing thickness of the oxide film is so set that it may grow according to a curve 8 at diffusion temperature 6T. So, immediately after the diffusion start, the thickness of growing film is almost zero, and Sb diffuses easily into the semiconductor substrate 1. Further, when the temperature rises up to diffusion temperature 7T, the thickness of the growing film accelerates according to a curve 9, but since there is already an oxide film, the supply rate is controlled and further, since the side of Sb diffusion speed is set quicker, Sb diffuses without breaks. Hereby, it becomes possible to lower sheet resistance in a short time.

Title: Magnetic recording/reproducing device
Inventor: YAMAZAKI YUJI
IPC: G11B15/18
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic recording/reproducing device capable of reducing space and costs. SOLUTION: A lug 18c is formed in one end of a tension band tensing lever 18, and a feeding reel base 15 is locked by engaging a reel base gear 15a. By rotating the tension band tensing lever 18 clockwise as shown, the lug 18c is separated from the reel base gear 15a to release the rotational locking of the feeding reel base 15, thereby making a feeding reel 16 rotatable. Also, by simultaneously pressing a tension band 7 with a band pressing portion 18a, the tension band 7 is pulled to be wound on the feeding reel base 15, thereby serving as a tension support. Since the tension band spreading lever 18 operates also as the rotation locking member of the feeding reel base 15, the necessity of separately providing a locking member is eliminated.

Title: Blowing apparatus for air conditioning machine
Inventor: SAKATA YUJI
IPC: F24F1/00
Filed: 1987-05-11
Abstract: PURPOSE:To adjust the flow of air in the low pressure portion of an outdoor side air circulation, control the generation of an eddy and carry out an air blast efficiently, by a method wherein a partition plate between the high pressure portion of the outdoor side air flow path and the low pressure portion thereof is provided with communicating passages for communication of the high pressure portion with the low pressure portion and, further, flow straightening means are provided on the low pressure portion side of the communicating passages. CONSTITUTION:In ordinary operations, a fan 11 blows air from a suction port 2 of an outdoor side blast circulation 4 toward a blowoff port 3 thereof. In this case, air pressure in the outdoor side blast circulation 4 is divided in two portions in positioning relationship between a partition plate 5 and the fan 11 and, consequently, a low pressure portion 6 and a high pressure portion 7 are formed. As a result, an eddy 14 which whirls counterwise to the rotary direction of the fan 11 is generated in each of the four corners of the low pressure portion 6. Therefore, communicating passages 12 are provided in the partition plate 5 so as to permit air in the high pressure portion 7 to flow therethrough into the low pressure portion 6. This flow of the air is smoothened by flow straightening means 13 so that the whirl of the eddy 14 is regulated in a direction along the rotary direction of the fan 11. Accordingly, by flowing the suitable amount of the air to these flow straightening means 13, the operation can be carried out efficiently in a comfortable condition of suppressing noises.
