Title: Semiconductor device
Inventor: SHIRAI KOJI
IPC: H01L29/08
Filed: 1984-11-29
Abstract: PURPOSE:To prevent the generation of current loss and malfunction by sufficiently increasing the withstand voltage by a method wherein the shape of a depletion layer of a reversely biased planar junction is corrected to a smooth ideal form. CONSTITUTION:To set the title device of bi-polar type in action, forward bias is impressed between an emitter region 16 and a base region 15, and reverse bias is impressed between the regions 15 and 14. Accordingly, a depletion layer spreads in the neighborhood of the base-collector p-n junction, and a depletion layer spreads at the p-n junction of a field plate electrode 20 by reverse bias impressing. The electrode 20 in this state is equivalent to a capacitor using a depletion layer as the dielectric layer. Therefore, the gradient of potentials is formed at the depletion layer region even in the state of no current, and ideal field plate effect is applied to the surface of the region 14. As a result, a smooth depletion layer is formed in the surface close to the junction between the collector region and the base region 15 and increases the withstand voltage.

Title: Wheel for vehicle excellent in corrosion resistance and brilliancy
Inventor: YAMAGUCHI KEITARO
IPC: B60B3/00
Filed: 1996-09-03
Abstract: PROBLEM TO BE SOLVED: To improve the corrosion resistance and brilliancy of a wheel for a vehicle by forming a nonporous anodically oxydized film having prescribed thickness on a wheel material surface and applying a clear coating on the film. SOLUTION: The wheel material consisting of Al alloy is subjected to an anodic oxidation treatment. Since an electrolytic bath used for the treatment is a neutral aqueous soln. containing boric acid salts, etc., which are electrolytes hardly dissolving generated anodically oxydized films, a problem of waste water like in case of chromate treatment is eliminated. The anodically oxydized film obtained under an appropriate electrolysis condition has 150 to 500 angstrom thickness, is uniform and nonporous and has < 10% vacancy ratio. Further, water content of the film is very low and <=5% and anion content is also very low and 2wt.%. Sufficient corrosion resistance, brilliancy and adhesion property can be obtained by adjusting film characteristics within a range described above. Then, the clear coating is applied on the oxydized film as in the conventional manner.  Thickness of the coating film is preferably 15 to 25μm in order to hold excellent corrosion resistance and brilliancy.

Title: Method and mechanism for controlling pressure in processing chamber
Inventor: YAMAZAKI HIDEO
IPC: G05D16/00
Filed: 1991-06-27
Abstract: PURPOSE:To prevent hot air, fire, exhaust gas and dust or the like from being blown out by executing feed forward control to reduce pressure rather than set negative pressure in feedback control before generating the cause of rapidly increasing the pressure. CONSTITUTION:When the inside temperature of a furnace 3 is lowered, a signal to further lower the inside pressure of the furnace rather than a value set by the feedback control is transmitted from a controller 42, to which signals are transmitted from a temperature sensor 40 to a temperature control gauge 41, to a pressure control gauge 44 before transmitting operation signals to a stabilizing burner 11. A signal to enlarge the opening degree is transmitted from the pressure control gauge 44 to an exhaust air damper 27 and according to this signal, the large opening degree is maintained until the inside pressure of the furnace is enough lowered. In this case, the operation signals are transmitted from the controller 42 to the stabilizing burner 11, the burner 11 is turned to an ignition state, and the inside pressure of the furnace is rapidly increased. Since the inside pressure of the furnace is set enough low in advance, however, the inside of the furnace is not turned to positive pressure, and fire or the like is prevented from being blown.

Title: Extension and contraction protecting cover
Inventor: OKAMURA MITSUO
IPC: B23Q11/08
Filed: 1986-10-24
Abstract: PURPOSE:To permit extension and contraction with a small load collectively, by integrally forming an entire member in a spiral shape and setting a free length to which no external force is applied sufficiently smaller than the maximum mounting length in use and setting a ratio of a plate thickness to the minimum inner diameter between 0.002-0.008. CONSTITUTION:A cover, which is mounted on a shaft portion of various kinds of devices, changes its mounting length in use, as the shaft part operates. Its load can be made smaller than that required conventionally even if the shaft portion is at any arbitrary position by setting a free length S sufficiently smaller than the maximum mounting length in use. In addition, a ratio of its plate thickness t to the minimum inner diameter d is set between 0.002-0.008 which is considerably smaller than a conventional ratio so that both of a sliding resistance caused among band-shaped members forming a spiral shape in expansion and contraction and an elastic force in the direction of a shaft center can be reduced. As a result, the expansion and contraction are collectively possible with a small load, whereby a load applied to the devices is made smaller. Therefore, the devices can be stopped and operated without anxiety.
