Abstract: PURPOSE:To prevent the clogging of a pipeline due to the solidification of the raw gas at the time of forming an oxide superconductor film on a substrate by chemical vapor deposition by forming the raw gas feed mechanism with a main pipeline and a by-pass pipeline. CONSTITUTION:An oxide superconductor film is formed on a substrate by chemical vapor deposition. In this case, a mixture 11 of the vaporized raw gas with an inert gas such as Ar as the carrier gas is supplied from the inlet 21 of a raw gas feeder 10, the main pipeline 12 for the raw gas 11 is heated by a heater 20 to keep the raw gas gaseous, and the raw gas is supplied to an oxide superconductor film forming reaction vessel from the outlet 22. Meanwhile, when the supply of the raw gas is stopped, a valve 15 is closed and a valve 16 is opened to pass the raw gas through the by-pass pipeline, the raw material component in the raw gas is solidified by a cooler 18, only the Ar as the carrier gas is passed and discharged from the outlet 22, and the solidified raw material is recovered from the cooler 18 and reutilized. As a result, the main pipeline 12 is not clogged by the solidification of the raw gas, and productivity is not decreased.

Title: Fault diagnosing circuit
Inventor: ASHI MASAHIRO
IPC: G01R31/28
Filed: 1986-09-19
Abstract: PURPOSE:To simplify a logic circuit and to facilitate logical analysis without using any logic element by providing a diagnosis dedicated circuit which sets and resets FFs in the logic circuit independently of one another. CONSTITUTION:Serial DATA1' contains specification information on FFs to be set and reset and this information is extended into a parallel signal when inputted to an S/P converter 1. Then a decoder 3 generates a set signal and a reset signal with an input signal and sends them out to specified FFs through buses 6 and 7. Circuit blocks are so divided that there are not plural FFs which are set and reset in the same circuit block at the same time, and the number of decoding terminals is determined. A signal for diagnosis is outputted to a selector 5 through a signal bus 9 as to transfer signals among respective circuit blocks. On the other hand, DATA2' which contains selection control information on the selector 5 is expanded into a parallel signal by an S/P converter 2 and a diagnostic result is selected by the selector 5 and outputted.

Title: Scanning type image reader
Inventor: IIZUKA TAKAYUKI
IPC: H04N5/372
Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To correct a curved image of an image pickup lens by changing a position in an optical axis direction of a line sensor or an image pickup lens in response to a position of a line sensor scanning. SOLUTION: An elliptic projection 21 having a major diameter in an optical axis direction X is engaged with a long hole 33 to hold a sensor unit 20 slidably in the direction X only. The width of the long hole 33 is selected to be the same as a minor diameter of the projection 21 so as to disable the rotation of the unit 20 and a light receiving face of a line sensor 2 is kept always perpendicular to the direction X. The holder 32 is moved in a direction Z along a guide member 40 by the turning of a drive shaft 31 to change the position in the direction X while making scanning by the unit 20. Thus, the unit 20 makes scanning along a curved image face formed by an image pickup lens while keeping a light receiving face vertical in the direction X and correction is cancelled for the curved image of the image pickup lens as to the direction Z and an image focused entirely is obtained.

Filed: 1991-08-30
Abstract: PURPOSE:To reduce the convergence time of a jitter compensation value to an optimum value in the jitter compensation device with respect to a transmitter provided with the jitter compensation device compensating the jitter caused in a DPLL for controlling a sampling phase of a reception signal onto an echo canceller in a digital subscriber line transmitter or the like. CONSTITUTION:A dummy jitter generating control means 109 allows a DPLL 107 to generate forcibly a dummy jitter whose jitter direction is changed alternately in the forward/backward direction, for example, at, e.g. a prescribed time interval. Based on the operation above, a jitter compensation device 108 updates each jitter compensation value in the said device for each prescribed time as above, for example. Thus, each jitter compensation value is quickly converged to an optimum value in the jitter compensation device till a true jitter takes lace in the DPLL 107 after the start of operation of the transmitter.

CONSTITUTION:Pressurized oil is leaked from an inlet 12b to an outlet 12c, and the set hydraulic pressure Pd of a pressure compensation valve 8 is lowered. A check valve 7 is closed by said action, and further when the pressure PL is risen, flowing is started by the relief action of a peak cut valve 13. At that time, the auxiliary pump circuit pressure is lower than the main pump circuit pressure. What is relieved from the peak cut valve 13 is only the discharge flow rate from a main pump l. When the relief action of the relief valve in the main pump circuit is started by the combination of fixed pump, the relief valve in the auxiliary pump circuit is linked and relief action is started without anything to do with the set pressure, and smooth change of flow rate and pressure can be carried out without shocks by said constitution.

Title: Planetary gear type reduction gear
Inventor: SUZUKI KAZUHIRO
IPC: F16H1/32
Filed: 1988-09-02
Abstract: PURPOSE:To realize cost cut and suppress noise and obtain the high reduction gear ratio by revolving planetary gear in a fixed internal gear through rotation by the revolution of an input shaft and reducing speed by the difference of the number of teeth for an internal gear in each revolution and taking out the revolution from an output shaft. CONSTITUTION:When a motor 12 revolves, an input shaft 2a revolves, and a planetary gear 4a revolves, rotating in the meshed state with a fixed internal gear 5a. When the planetary gear 4a revolves by one circumference, the gear 4a has the number of gears less by one piece than that of the internal gear 5a, and the gear 4a rotates by the portion of one piece in the reverse direction to the revolution direction. Therefore, speed is reduced to 1/91 between the input shaft 2a nd the gear 4a. Since the first stage reduction gear 1A and the second stage reduction gear 1B are directly connected, the total reduction ratio becomes 1/8281 which is the result of the multiplication of the reduction ratio in each stage. Since the whole reduction gear is simple and does not use a special structure, cost cut can be realized, and the gears 4-6 are in the meshing between the external gear and internal gear, and noise can be suppressed.

Abstract: PURPOSE:To complete the passivation of the surface further, and to prevent a defective contact in a mounting process on assembly while considerably thickening the thickness of glass attached to a mesa groove on the back side by forming mesa grooves to both surfaces, removing the oxide film of the mesa shoulder section only of the surface in an extent of which the oxide film slightly backs from the end surface of the mesa shoulder section and electrodepositing glass. CONSTITUTION:Processes up to a process in which the mesa grooves of both surfaces are formed through etching are the same as a conventional method, the mesa grooves 3a, 3b are formed, and the oxide film in the mesa shoulder section is removed only to the oxide film 2a of the surface. The mesa shoulder section of the mesa groove 3b on the back side is brought to the state in which a lip 2d is projected because the oxide film of the back is left as it is. When treatment to the oxide film 2a of the surface is completed, an exposed silicon surface is etched by approximately several micron between the end surface of the oxide film 2a and the mesa shoulder section of the mesa groove 3a on the surface side as required. Accordingly, the oxide film in the vicinity of the mesa shoulder section of the mesa groove 3a on the surface side is removed to some extent, and a silicon surface 6 is deepened by approximately several micron through etching, and glass is electrodeposited.
