Title: Control method for railroad vehicle on mild curve
Inventor: ISHIKAWA RYUTARO
IPC: B61F5/10
Filed: 1989-08-24
Abstract: PURPOSE:To prevent a vehicle body from colliding with a stopper by controlling the cant gradual decrease on a mild curve so that the average height of the right and left air springs of front and rear dollies and the relative rolling angles between the vehicle body and dolly of front and rear dollies have the same magnitude and opposite symbols. CONSTITUTION:The auxiliary air chamber 3-1 of an air spring 3 is fitted to a dolly frame 2, and an outer tube 3-2 is kept in contact with the bottom face of a vehicle body 1. An intake pipe 4 with an electromagnetic intake valve 5 through the outer tube 3-2, an electromagnetic exhaust valve 7 and a pressure sensor 8 are arranged. The above valves 5 and 7 are opened or closed based on detected signal of a height sensor 9. The cant gradual decrease on a mild curve is detected from the difference of relative rolling angles between the vehicle body 1 and a dolly of front and rear dollies. It is controlled so that the average height of the right and left air springs of dollies satisfies the target value and the above relative rolling angles have the same magnitude and opposite symbols.

Abstract: PURPOSE:To improve the contacting state (the head touch) between a magnetic tape and a magnetic head in a rotary drum device mounting a movable head being used in a video tape recorder(VTR), etc. CONSTITUTION:In a rotary drum device in which the upper end of a fixed drum 1 is arranged at a position lower than a position where a movable head 5 is displaced to the lowest end in order to secure a movable range to the lower side of the movable head 5, the lower end of the outer peripheral part of a rotary drum 11 is extended to the side of the fixed drum 1 by the amount of the displacing quantity 11a to the lower side of the movable head 5. Then, the gap at a tape sliding plane between the fixed drum 1 and the rotary drum 11 can be narrowed owing to the extended part 11a of the rotary drum while the movable range of the movable head 5 is secured. Thus, the deformation of the magnetic tape in the gap between the fixed drum 1 and the rotary drum 11 is made small to improve the head touch.

Title: Method of treating silicon surface
Inventor: TATENO TOSHIO
IPC: H01L21/304
Filed: 1990-08-22
Abstract: PURPOSE:To restrain or prevent that a spontaneous oxide film is produced on the silicon surface by a method wherein the silicon surface of a product made of silicon is treated with ultrapure water or pure water to which HF of a specific concentration is added. CONSTITUTION:The silicon surface is dipped in pure water to which hydrogen fluoride of a concentration of 0.1 to 1000ppm is added, or the silicon surface is washed by pure water. Thereby, it is restrained that a spontaneous oxide film is produced on the silicon surface according to the concentration of HF in the pure water which contains HF, and it is possible to restrain that the spontanous oxide film is produced on the silicon surface in an atmosphere of dry air. Since the pure water used for this treatment contains HF in only extremely small quantities, it has also a function to clean the silicon surface without losing the intrinsic characteristic of a cleaning operation by the pure water. It is possible to restrain or prevent that the spontaneous oxide film is produced on the treated silicon surface even when the dissolved oxygen amount in the pure water and the oxygen and steam concentration in an air atmosphere for drying use after that are not reduced.

Title: Method for fermenting bread dough and apparatus therefor
Inventor: YAMAMOTO TATSUYA
IPC: A21D8/02
Filed: 1988-09-01
Abstract: PURPOSE:To prevent reduction in head volume with decreasing fermentation time and obtain bread rich in flavor by fermenting a head dough in a gaseous carbon dioxide-enriched atmosphere. CONSTITUTION:Fermentation is carried out in a gaseous carbon dioxide-enriched atmosphere in fermenting a bread dough. Gaseous carbon dioxide can be dissolved from the outside in the dough in addition to gaseous carbon dioxide generating from the bread dough itself during fermentation to increase the volume of the dissolved gaseous carbon dioxide in the bread dough, reduce the fermentation time and simultaneously increase the bread volume. The afore- mentioned method is effective in fermenting the dough at the normal fermentation temperature (30-38 deg.C) or below, especially <=25 deg.C for especially enriching the flavor and reduction of volume is further prevented in freezing and preserving the bread dough after fermentation. At this time, pressure of the atmosphere is ordinary or a slight positive pressure. Thereby, the volume of the dissolved gaseous carbon dioxide in the head dough can be increased to reduce the fermentation time or improve increasing action on bread volume.
