The present invention provides OLEDs of the top emission type comprising organic light-emitting (LE) elements by preventing the problems such as the widening of the power lines, the reduction in the aperture ratio caused by the widening of the upper and the lower capacitor electrodes and the short circuit between the upper and the lower electrodes caused by the roughness of the flattening layers. Two kinds of the OLEDs are provided. One is an OLED comprising a region of LE layer sandwiched between the upper and lower electrodes is formed on a power line of TFT for driving the pixel. Another comprises a region of the LE layer formed on an electrode of capacitor connected to the TFTs to control the light-emitting element. Accordingly, without forming a flattening layer on the light-emitting layer, there is no electric short circuit between the lower electrode and the upper electrode.

A hydraulic motor system minimizes wasted power by using a plurality of fixed displacement hydraulic motors to drive a drive shaft in a cooperative manner. The motors are selectively switched into operation in response to variations in fluid pressure. As a consequence the hydraulic fluid acts upon a motor system having an effective combined displacement for producing a predetermined shaft rotation rate at the volumetric flow rate which caused the pressure condition. The invention is disclosed as having particular utility for driving a cooling fan for an automotive engine.

Hydraulic motor system

PURPOSE:To enable to efficiently dissolve heat storage material during heating by a structure wherein heating is performed by providing heating sources, one of which covers the bottom surface and the other of which is vertical to the bottom surface, at the lower part of the heat storage device in a latent heat type heat accumulator, which stores and releases heat by means of phase change. CONSTITUTION:The heat storage device A consists of the heat accumulator 1, the heat storage material 2, a heat exchanger 13 for heating and a radiator 4 for taking-out heat. The heat exchanger 131 for heating, which covers the whole bottom surface 6, and the heat exchanger 132 for heating, which is vertical to the bottom surface 6, integrally constitute the heat exchanger 13 for heating. During the initial stage of dissolution of the heat storage material, the heat storage material 12 is dissolved at the central portion of the heat accumulator 1 by means of the heat exchanger 132 for heating on a form so as to pierce the heat accumulator 1, resulting in leaving undissolved heat storage material 22 on the upper wall surface in the heat accumulator 1. The undissolved heat storage material 22 is dissolved by obtaining heat from dissolved heat storage material 12 lying in the bottom and the central portions of the heat accumulator 1 and developing the convection of the dissolved heat storage material throughout the whole portion of the heat accumulator 1.

PURPOSE:To reduce the weight, reduce the cost and improve the reliability of a lamination type heat exchanger to be used for the heat exchange between the liquid as the fluid and the two-phase flow of gas and liquid accompanied with the phase change. CONSTITUTION:Brazing is executed by inserting the brazing filler metal 38 of flat plate shape onto the upper surface of the plates 24, 26 in manufacturing the integrated structure through the lamination of a plurality of sets of the flat plates 24, 26 where slits 27, 33 to be the respective flow passages of the heat exchanging fluid are formed, and the plates 25a, 25b forming the bulkhead for the heat exchanging fluid during the lamination in the order of 24, 25a, 26, 25b. Joining of the plate 26 with the plate 25a can be surely executed because the brazing filler metal 38 is present therebetween. Joining of the plate 26 with the plate 25b is executed by circulating a part of the brazing filler metal 38 melted by the temperature rise on the plate 25b through the slit 33 provided in the plate 26. Joining of the plate 24 is executed in the same manner. Thus, the amount of the brazing filler metal can be reduced, and the blocking of the flow passage by the overflow of the excessive brazing filler metal can be prevented.
