Title: Solar cell
Inventor: TSUKAMOTO MORIAKI
IPC: H01L31/04
Filed: 1987-02-17
Abstract: PURPOSE:To raise the efficiency of a solar cell by absorbing a light of a wavelength range having low photoelectric conversion efficiency in a photoelectric conversion layer, and forming a wavelength converter layer for irradiating a light of a wavelength range having high photoelectric conversion efficiency in parallel with the photoelectric conversion layer. CONSTITUTION:A solar light incident to a reflection preventive film 1 is incident to a wavelength converter layer 3 through the film 1 and a transparent protective cover 2. The wavelengths of the incident light range over 0.3-5mum. Of them, the light of 0.3-0.5mum of wavelength having low photoelectric conversion efficiency is absorbed by the layer 3, converted to the wavelength of 0.5-0.6mum to be irradiated. The light having the wavelength of 0.5mum or longer not absorbed by the layer 3 is transmitted as it is through the layer 3, a transparent adhesive 4 and a transparent electrode 5 to be incident to a photoelectric conversion layer 6 formed in parallel with the layer 3 to be converted to power. The light having the wavelength of 0.5-0.6mum irradiated from the layer 3 is radiated from a light irradiation point in all directions and incident to the layer 6 to be converted to power.

Title: Working machine controller
Inventor: NISHIMOTO MASASHI
IPC: B66F9/22
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To prevent, to the full extent, the driven speed of a hydraulic actuator already driven, which is used in a working machine employing oil quantity control in simultaneously driving its plural hydraulic actuators, from suddenly changing under the influence of another hydraulic actuator additionally driven. SOLUTION: While an oil-quantity limitation determining means 33 outputs oil-quantity limiting signals (f), a controller for a working machine changes its control characteristics so as to gradually change the driven speed of one hydraulic actuator 9 adapted to be changed in driven speed corresponding to a change in the operated degree of a control lever, typically a telescoping lever 21, and also the driven speed of another hydraulic actuator, typically a revolving hydraulic motor 11, adapted to be changed in driven speed corresponding to a change in the driven speed of the former hydraulic actuator 9.  That system minimizes deceleration in the driven speed of the latter hydraulic actuator 11 under the influence of oil quantity limitation resulting from the drive of the former hydraulic actuator 9 and accordingly suppresses driving shocks caused by the deceleration of the latter hydraulic actuator 11, which control in turn improves the operational feeling of the working machine.

Title: Liquid developing device
Inventor: UEMATSU RYOSUKE
IPC: G03G15/10
Filed: 1988-02-16
Abstract: PURPOSE:To reproduce a uniform solid black and a fine no-blur electrostatic latent image by constituting a carrier which conveys liquid toner to a development area so that the surface of carrier consists of a conductor part connected to a developing bias potential supply part and dielectric parts. CONSTITUTION:The surface of the developing sleeve 10 consists of two areas, i.e. the exposed conductor part 11 of a conductive carrier base part and the dielectric parts 12. When a thin film of liquid toner 14 is formed on the developing sleeve 10 and a photosensitive drum 15 and the developing sleeve 10 comes closer to each other, projects of the liquid toner are easily formed at the part of the conductor part 11. This projection formation is determined by the arrangement of the conductor part 11 which is formed previously on the carrier, so the projection formation is not one-sided even in a uniform solid black electrostatic latent image 16a. Further, projections parts are formed individually for nearly electrostatic latent images 16b and 16c. Consequently, uniform solid black development is performed and a fine latent image having no blur is reproduced.
