Title: Forming method for sio2 insulating film
Inventor: OOSAKI TAKAAKI
IPC: H01L21/316
Filed: 1979-09-03
Abstract: PURPOSE:To decrease side etching by a method wherein the SiO2 insulating film is spatterred by high frequency, controlling the pressure of gas and minuteness is improved with approach to the surface. CONSTITUTION:When spattering the SiO2 film on a semiconductor substrate 1 by high frequency, the pressure of Ar gas is reduced with lapse of time (for example, 3X10<-4>Torr from 4X10<-3>), and the SiO2 film 5 is formed. Consequently, if an etching mask 8 is formed and the film 5 is etched by an etching liquid of NH4F: HF=4:1, side etching is l', and the side etching is made smaller than side etching l in the case when the constitution of the film 5 is uniform. Thus, the width of a wiring layer is reduced and the wiring layer is highly integrated while a wetproof property and stability can be improved because of high minuteness with approach to the surface.

Title: Extraction steam pipe
Inventor: IZEKI TAKASHI
IPC: F01D25/00
Filed: 1991-05-16
Abstract: PURPOSE:To distribute steam quantity and water quantity so as to be approximately equal to each other by branching off the first branch pipe connected to a feed water heater from the back side direction of a bent pipe of a master pipe, providing a straight pipe having inside diameter specific times as large as that of the master pipe on the master pipe side, and providing the second branch pipe connected to a hygroscopic moisture separator. CONSTITUTION:An extraction steam pipe is constituted in such a way that the first branch pipe connected to a feed water heater 23b immediately after a bent pipe 2 is branched off from the back side direction of the bent pipe 2 of a master pipe 1, that a straight pipe having inside diameter 3-4 times as large as that of the master pipe is arranged on the master pipe 1 side, and that the second branch pipe connected to a hygroscopic moisture separator 15 is provided. In the case when two phase flow of air current introduced from a steam turbine 13 passes through the bent pipe 2, since centrifugal force acts on liquid films and droplets in the pipe, the liquid films and the droplets are deflected to the back side of the bent pipe 2, so that a large quantity of water can be separated by means of the branch pipe arranged immediately after the bent pipe 2. Hygroscopic moisture in the whole of the master pipe 1 is reduced afterwards, and moreover, since a guide vane 6 is attached to the bent pipe 2, the flow is straightened afterwards, and enters into the branch pipe equally, so that steam quantity and water quantity can be distributed so as to be approximately equal to each other.

Filed: 1988-05-09
Abstract: PURPOSE:To improve the quality of a cast strip and to prevent clogging of a nozzle by vertically setting the two endless metallic belts having long and short lengths and also the short belt below the long belt and arranging the molten metal supplying trough just above the short belt. CONSTITUTION:Two endless metallic belts 1b, 1a having long and short lengths and circulatedly driven with driving rollers 2, are vertically set and also the short belt 1a is set a little below the long belt 1b. Further, the molten metal supplying trough 7 is set just above the short belt 1a. At the time of pouring a molten metal 6 into a casting space M through the molten metal supplying trough 7, the molten metal 6 is sequentially cooled to form the cast strip 9. Then, the molten metal head becomes high because of vertical type casting and a solidified shell 8 is uniformized. Further, as molten metal supply is executed through the trough 7, the problem of the nozzle clogging is eliminated. By this method, the quality of the cast strip 9 is improved and the nozzle clogging is prevented.

IPC: G01C19/72
Filed: 1991-04-18
Abstract: PURPOSE:To obtain a phase modulation type optical fiber gyro which is small in size and light in weight and of which the detecting precision can be improved with ease. CONSTITUTION:An input-output end of light existing in an optical system of an optical fiber gyro is provided with an end face B' which is to be a reflection preventing means, and thereby reincidence of reflected light on an optical fiber loop is suppressed. Besides, a coherent light source element and a light output element are provided with pulse modulating means discretely and a harmful component is removed by an analog or digital processing. The reflection preventing means operates so that it prevents a signal light from being reflected by an end face, reentering an optical fiber 206, making a round through the optical fiber loop and becoming the signal light again, while the pulse modulating means operate so that they select only an effective component by modulating the coherent light source element and the light output element synchronously. Accordingly, the effect of a reflected light is eliminated and thereby detecting precision can be improved.

Filed: 1978-09-14
Abstract: PURPOSE: To eliminate unforeseen troubles, by checking a gear shift to the top of a sub-transmission from the reversing position of the main transmission.  
     CONSTITUTION: When the gear is put in the reverse, a shaft unit 44 is turned around a shaft 41 in the other way of the arrow B. A gear shift arm 61 is engaged with a reverse fitting piece 69, a projection 53 is protruded leftward against a fitting cylinder 49, and a fitting piece 85 is fitted being advanced in the swing locus of a fitting arm 91. As a result, the turning motion of an arm 29 is restrained so that it cannot press a high-speed tension pulley 21 toward a belt 9. Since the motion of low-speed tension pulley 27 is not prevented, a sub-transmission is connected to the low gear. That is, the gear of the main transmission 38 can be changed to the high or low when it is in the reverse, while the sub-transmission 2 cannot be connected with the high but only with the low.
