Title: Device for preventing meandering motion of belt
Inventor: KANEMOTO KENJI
IPC: B65G39/16
Filed: 1982-07-23
Abstract: PURPOSE:To allow a meandering motion of a belt to be responsively corrected with simple and inexpensive constitution, by providing wheels supporting a belt so as to be directed reversely to the meandering direction and to be rotated in the horizontal direction, and mechanically connecting means for sensing the meandering action of the belt to the wheels. CONSTITUTION:When a belt 8 meanders to the left side with respect to an advancing direction of the belt, for example, a left side roller 10 is pushed by a side edge of the meandering belt 8, and is moved by the amount of such a meandering. As a result, an arm 7 is simultaneously rotated by the same angle of rotation of the side roller 10 through a rod 12, a turnbuckle 13 and a rod 11, and accordingly, a rocking cylinder 4 for supporting a wheel, which cylinder being formed integrally with the arm 7, is simultaneously rotated around a support shaft 2 in the same direction. As a result, wheels 5 and 6 are directed reversely to the meandering direction of the belt 8 to correct an advancing direction of the belt 8. After correction of the advancing direction of the belt 8, a support arm 9 of the side roller 10 is returned to its original position by means of a force of a spring 15, and accordingly each of the wheels 5 and 6 is also returned to its original direction.

Title: Antireflection film of plastic lens
Inventor: KOMURA SUSUMU
IPC: G02B1/113
Filed: 1987-05-26
Abstract: PURPOSE:To improve the scratching resistance and durability of an antireflection film by providing a film contg. a metal oxide on the uppermost layer of said film. CONSTITUTION:A hard coat layer 2 of an org. material, a ZrO2 film 3, an SiO2 film 4, a ZrO2 film 5 and a mixed film 6 are successively deposited on a base plate 1 of a plastic lens. The film 6 is formed of binary vapor deposition of, for example, a mixture composed of SiO2 and MgF2 and Al2O3. The above- mentioned mixture having a low m. p. evaporates more in an initial stage and the Al2O3 having a high m. p. evaporates in the late period in this case; therefore, a heterogeneous film having the Al2O3 layer is formed in the uppermost part. ZrO2 or TiO2 is also usable in place of the Al2O3. The scratching resistance and durability of the antireflection film is thereby enhanced without impairing the optical characteristics thereof.

Title: Waste heat recovery heat exchanger
Inventor: SUZUKI TSUNEO
IPC: F22B1/18
Filed: 1989-05-24
Abstract: PURPOSE:To prevent water hammering or instability in the quantity of feed water to a steam drum from occurring and enable a uniform distribution of exhaust gas temperature to be obtained at an outlet of an economizer, by a construction wherein all flows of feed water in heat exchanger tubes on the upstream side with respect to an exhaust gas flow on which steam bubbles might be generated in the heat exchanger tubes during a low-load operation are upward flows, and downward flow of the feed water is permitted in non-heating connection tubes. CONSTITUTION:Feed water 4 first flows upward through heat exchanger tubes 51 in a heat exchanger tube panel 54b into an upper header, then flows through a connection tubes 55a into an upper header 52 of an adjacent heat exchanger tube panel 54b on the upstream side with respect to an exhaust gas flow, and flows downward through heat exchanger tubes 51. Then the feed water 4 flows upward and downward repeatedly in the panels 54b, and flows through a connection tube 55b or 55c into a lower header 53 of a heat exchanger tube panel 54a. The feed water 4 then repeats upward flow through the heat exchanger tubes 51 and downward flow through the connection tube 55b or 55c, and is fed out from an economizer 23 to a stream drum. Variations in the flow of feed water due to generation of steam bubbles and the accompanying water hammering or instability in the quantity of feed water supplied to the steam drum can be prevented from occurring, and a substantially uniform temperature distribution on a practical basis can be obtained at an outlet of the economizer 23.

Title: Congestion reduction system in signal transfer station
Inventor: KAJITANI MASAHIRO
IPC: H04L45/247
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To prevent a congestion state from being propagated to a signal network in the case that a signal transfer station (STP) detects the congestion state of a user signal to a called station or receives a congestion notice signal (TFC) from other STP. SOLUTION: A common line signal network adopting this system is made up of a stored program exchange and STPs use a TFC to make congestion control. In the case that a STPA detects a congestion state of a SEPa being a subscriber or receives a TFC(a) from a STPB that detects a congestion state of the SEPa, the STPA does not immediately send the TFC(a) to a caller station of the user signal (a) that designates the SEPa in the congestion state to be a called station, but the STPA bypasses the user signal to other route to the SEPa.

Title: Irradiation method
Inventor: KANEMATSU NOBUYUKI
IPC: A61N5/10
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To achieve an irradiation as planned by arranging a fifth process for switching a layer with which a particle ray beam is irradiated at a timing determined by a fourth process to previously clarify a distribution of a dose irradiated to an affected part at a planning stage, which enables setting of the parameters for an apparatus corresponding to the distribution of the dose. SOLUTION: Irradiation is started (S101) and a dose of an integral monitor is always read out during the irradiation to a certain split layer (S102) to be always compared with a projected monitor dose used in the subsequent procedure (S103). When the dose of the integral monitor reaches the projected monitor dose, immediately, with the altering of setting in the execution of a fixed procedure, for example, an irradiation to the subsequent split layer is carried out. (S104) The monitor returns to the dose monitoring mode again and repeated up to the end of the irradiation.  (A106) In the supervising of the integral monitor, fast repeated reading therefrom must be done but in stead, preset sealers or the like can be used if necessary and an interrupt processing is carried out according to the values on the dose monitored by a control calculator thereby getting rid of useless reading loop.

Title: Scroll fluid machine
Inventor: SUEFUJI KAZUTAKA
IPC: F04C29/00
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To improve durability and elongate life of a scroll fluid machine by effectively receiving thrust load from a turning scroll. SOLUTION: In this type of scroll fluid machine, a substantially spherical mating surface 18A composed of a large circular are C1 is formed on an end face of a columnar body 18 composing a thrust load support mechanism 13. Stress by the thrust load from a turning scroll 7 can thus be received by the mating surface 18A in a diffused manner. Abrasion and damage can be prevented therefore of load receiving members 14, 15, and the columnar body 18. Spherical bodies 20, 20 are fitted respectively between first and second recessions 16, 17 and columnar body side recessions 19, 19. It is thus possible to prevent dislocation between the load receiving members 14, 15 and the columnar body 18. Partial abrasion is thus prevented in the load receiving members 14, 15 and the columnar body 18.
