Title: Fluid seal ring
Inventor: SAKATA TATSUE
IPC: F16J15/18
Filed: 1985-05-25
Abstract: PURPOSE:To prevent the salability of a fluid seal ring from lowering during temperature change, by making the outer diameter of a fluororesin seal ring larger than the bore diameter a cylinder by a predetermined rate. CONSTITUTION:Fluid seal rings 1, 2 are fitted in ring grooves 4 formed in the outer peripheral surface of a rotary shaft 3 disposed in a cylinder 6. The outer diameter of the rings 1, 2 is made to be larger than the bore diameter of the cylinder by about 0.1-0.8%, and therefore, even if the rings 1, 2 contract due to temperature change, the entire peripheral surface of each ring is prevented from being separated from the inner surface of the cylindrical bore, thereby it is possible to sustain the salability of the fluid seal ring.

Abstract: PURPOSE:To provide a highly precise electric-signal/air-pressure conversion unit which is improved in the vibration resistance and the impact resistance and can be easily made small in size and in weight by effectively combining the electrostrictive element with the non-bleed type pilot valve. CONSTITUTION:In an electric-signal/air-pressure conversion unit body 10, a flapper 22 made of an electrostrictive element is made to approach a discharge port of a nozzle 18 through application of voltage to cause an increase in the back pressure of the nozzle 18.

Title: Formation of amorphous thin film
Inventor: KUDOU ATSUSHI
IPC: H01L21/203
Filed: 1984-06-01
Abstract: PURPOSE:To enable an amorphous Si film with high photoconductivity to be obtained at a relatively low substrate temperature, by employing a cluster ion beam, and optimizing conditions such as the introduced hydrogen pressure and the ionic current. CONSTITUTION:Si 10 is filled in a hermetically sealed crucible 11 having an injection nozzle 12 and is heated and thereby vaporized. This Si vapor is injected from the nozzle 12 into an atmosphere containing as a main component hydrogen having a pressure sufficiently lower than that of the Si vapor, i.e., a pressure of 20-80mPa. At this time, the Si vapor is supercooled by adiabatic expansion and forms a so-called cluster. In addition, a part of the Si vapor, together with the gas containing hydrogen as a main component and introduced into the evaporation chamber through a piping 13, is ionized by electrons emitted from an ionizing filament 14 and is further accelerated by accelerating electrodes 15 so as to bombard the surface of a substrate 16, together with neutral particles, whereby Si is deposited on the substrate surface. Thus, it is possible to obtain an amorphous Si thin film with high photoconductivity at a low substrate temperature, i.e., 80-180 deg.C.

Title: Interference avoidance system for control channel
Inventor: SHIMIZU TAKESHI
IPC: H04W72/04
Filed: 1997-05-01
Abstract: PROBLEM TO BE SOLVED: To avoid interferences in an area, where interference takes place at all times by transmitting a link channel re-setup request, while selecting a frequency of a control channel in the case that an assignment reply cannot be received within a prescribed time with respect to a link channel setup request. SOLUTION: A protocol communication section 4 of a slave set sends a link channel(LCH) setup request to a control channel 6a, via a transmission data generating section. The control channel 6a controls the frequency of a transmission section 1a for frequencies of 13 control channels assigned at first, and the request is sent to a master set via an antenna. When no reply is received within a prescribed time, an LCH re-setup request is sent by the frequency corresponding to the 12th control channel. Thus, even in the case that pluralities of master sets are installed at a narrow place and the transmission through the 12th control channel receives interference at all times, since the transmission timing of the 18th control channel differs from each master set and no interference is caused at the 18th control channel, the interference is avoided.
