Inventor: YAMAMOTO TSUNESUKE
IPC: B41J2/165
Filed: 1993-05-24
Abstract: PURPOSE:To carry out suction work even when an ink tank becomes vacant preventing a nozzle communicating with the vacant tank from communicating with outside air at other part than a discharge opening when ink is to be sucked by one suction pump in a state that one ink tank among a plurality of ink tanks is vacant. CONSTITUTION:An ink jet printer comprises one or more ink jet head 1 having a plurality of nozzles for discharging liquid drops, one or more ink tank for supplying ink to the ink jet head 1 through an ink passage 2, and a sucking pump for sucking the ink from all nozzle discharging openings of the ink jet head 1 simultaneously.

Title: Method for controlling power of construction machine
Inventor: NISHIMOTO MASAHARU
IPC: F02D11/10
Filed: 1988-05-17
Abstract: PURPOSE:To suppress engine noise and wasteful fuel consumption at the time of operation by providing a means for detecting a travel neutral condition on a controller and, at the time of detecting the travel neutral condition, limiting the maximum revolving angle of a governor lever. CONSTITUTION:An neutral signal detecting means 13 installed on an advancing/ backing command transmitting means 11 sends a neutral signal to a controller 16. The controller 16 outputs a signal to an actuator 17 in proportion to the operating angle of an accelerator lever 10 or an accelerator pedal 12. At this time, however, since the neutral signal is being inputted, the output of the controller fails to get above a defined value. At the time of traveling, since no neutral signal is inputted, the controller carries out a high-speed traveling without being restricted.

Filed: 1978-10-03
Abstract: PURPOSE: To prevent the generation of a series resistance from increasing, by forming an acid-resisting metallic pipe on the surface of the side, on which a amorphous Si layer of a low-resistance substrate electrode is formed, so that an oxide is formed on the interface between the base board electrode and the amorphous Si layer.  
     CONSTITUTION: Layers 8 of Cr and Al are piled on a glass plate 7, and a Pt and a low-resistance Si containing a high concentration of P are thermally attached. The Si layer may be of either amorphous or multi-crystal. At this time, by being heat-treated at a temperature between 400°C and 900°C, a uniform silicified platinum layer 9 and a residual Si layer 2a are formed. An n-type high-resistance amorphous Si 3, a schottky barrier metal 4, an electrtode 5 and reflection preventing film 6 are formed on the layer 2a by glow-discharge using SiH 4 . As the layer 9 is capable of preventing a reaction between a metallic layer, such as Al, etc. and the low- resistance Si layer 2a and stabilized against high temperature, a good ohmic contact can be maintained between the layer 2a and the layer 8, a low resistance of the layer 2a can be satisfactorily maintained, and series resistance of a solar cell can be lowered.
