Patent JP-H03222890-A (JP)
Title: Rotary compressor
Inventor: WADA TOMIO
IPC: F04C29/02
Filed: 1990-01-25
Abstract: PURPOSE:To maintain the suction capacity of lubricating oil by installing each of first and second on-off valves at the inlet side of a cooling means and at the bypass pipe bypassing a bypass of this cooling means, and when inlet temperature in a feeding means becomes lower than that in a condenser, making the discharge gas so as to be directly passed to this feeding means. CONSTITUTION:Discharge gas derived from an outlet pipe 13 is cooled by a heat exchanger 17 as a first on-off valve 31 is opened in normal operation, and it is set down as inlet temperature in an injection pipe 18 and guided to a feed oil pipe 16, through which lubricating oil 15 is sucked in from a void 19 with this gas flow velocity. Inlet temperature in the injection pipe at this time is made into such a gaseous state, namely, higher than that in a condenser 21. When ambient temperature is very low, when a fact that the inlet temperature of the injection pipe 18 becomes lower than that of a condenser 21 is detected by sensors 35, 34, the on-off valve 31 is closed but the on-off valve 33 installed in a bypass 32 is opened instead. Therefore gas out of the outlet pipe 13 is directly fed to the injection pipe 18 without being cooled, so that the inlet temperature of the injection pipe 18 becomes higher than that of the condenser 21 at all times, thus any gas-liquid mixture is prevented from occurring and, what is more, suction capacity is well maintained.

Title: Current-sensitized thermal ribbon film
Inventor: OKAZAKI RYOTA
IPC: B41J2/33
Filed: 1986-01-27
Abstract: PURPOSE:To widen the range of use of a printer and save labor in inspecting a current- sensitized transfer printer, by constituting the main body of a ribbon film of a laminate of a high resistance layer film and a low resistance layer film. CONSTITUTION:The main body of a ribbon film is constituted of a high resistance layer film 1 and a low resistance layer film 2. When an electric current is supplied to the film from an electrode 3, a part 1a of the film 1 in the vicinity of the electrode 3 is heated. The heat is transferred to a thermal recording paper 4 through the film 2, thereby developing a color at a part 4a of the paper 4. In the cases of a current- sensitized transfer printer and a thermal transfer printer, relative movements of the ribbon film and the paper are prevented by a method wherein the ribbon film is held still in the printer during printing, a method wherein the ribbon film is taken up at the same velocity as the velocity of the electrode by a roller 5 provided as a return electrode on a carrier, or the like. As a result, the part 1a of the film 1 at which heat is generated through the function of the electrode 3 is separated from the electrode 3 immediately after the heat generation, and the electrode 3 comes into contact with a film part 1b at which heat is not yet generated, so that the electrode 3 itself will not be heated, and continuous energization and heat generation can be performed at a high speed.

Title: Tractor
Inventor: TAMADA TAKESHI
IPC: B60K17/28
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To eliminate an overload on a working device due to a reversal rotation by making a traveling gear shifter into down shifting, or operating engine speed into reduction at a time when a power takeoff transmission gear of a power takeoff shaft is transmitted in reverse, and maintaining its low speed running state. SOLUTION: When a selector gear of a power takeoff transmission gear is shifted to a reversing position from the normal rotation by an operating lever, a controller C outputs to four change clutch solenoid valves 36 to 39 of a traveling gear shifter by the detection of a reverse rotation detecting switch SW1, and a change clutch is shifted into reduction so as to make it come to a working travel speed suitable for the specified reversing transmission work. Differently, a solenoid 46 is operated by an output from the controller C, and a control rack controlling a fuel injection quantity of an engine is operated to the low speed side by the reverse rotation detecting switch SW1 turned to ON, making it into a low speed running state, whereby even if the gear shifter is erroneously operated to the high speed side, any excessive burden on a working machine is obviated, and thus any possible damage to this working machine and a tractor is prevented in this way.
