Title: Automatic load regulator
Inventor: IWAKI TOSHIO
IPC: H02P9/00
Filed: 1994-02-09
Abstract: PURPOSE:To regulate the load with no need of monitoring by setting the %-load arbitrarily in the load test at a generator. CONSTITUTION:Output from a generator is regulated at a rated value by controlling a water rheostat by means of a manual switch 37. An input bias regulator 12 regulates a %-load indicator 13 to indicate 100% load. A %-set switch 21 is then turned ON and a 100% set value is stored at an operating section 20. When the load of generator is altered at a-% setter 22, the operating section 20 operates the ratio with reference to the 100% set value and delivers a-% load set signal A. A comparison circuit 24 compares a-% load set value A with a %-load signal B and an automatic regulation control circuit controls the water rheostat to satisfy B=A.

IPC: B66F9/08
Filed: 1991-01-14
Abstract: PURPOSE:To improve durability in the structure of a lift cylinder support beam of a forklift, by welding a cylinder support plate to a side of an outer mast, apart from the rear of the outer mast by a fixed distance so as to install a support beam. CONSTITUTION:A circumferential part of a support plate 7, which is rectangular with its longer sides kept horizontal, is welded to a side of a mast in such a manner that the support plate 7 is projected backward from the mast. The welded part 9 in the circumference of the support plate 9 is located apart from the rear of the mast by a predetermined distance. Each of the left and right support plates 7 is provided with a square hole 7a, a square shaft portion 8a at each end of a support beam 8 is inserted into the hole 7a, and the fit-in part is welded. Since welding to the rear edge of the mast where tensile stress is large when a forward moment acts on the outer mast, decrease in mast strength due to welding can be avoided although the welding support beam 6 is welded to the outer mast 1 in this structure. The tensile stress acting on sides of the mast is far smaller than that acting on the rear of the mast.

Abstract: PROBLEM TO BE SOLVED: To improve light emitting efficiency of a LED and to improve the efficiency of a light receiving element by forming a thin film layer, wherein the irregular difference of lattice constant and a film thickness are specified in contact with a nitride semiconductor layer on a substrate, and forming an active layer comprising a nitride semiconductor including indium in contact with the thin film furthermore. SOLUTION: A thin film layer is the layer, wherein the irregular difference of the lattice constant with a nitride semiconductor layer formed in contact with the thin film layer is ±3% or more and the film thickness is 50Å or less. When the irregular difference of the lattice constant of the thin film layer with respect to the nitride semiconductor layer is ±3% or more, the large lattice strain is applied on the thin film layer. By this strain energy, the thin film layer does not grow in the flat two dimensions but grows in the three-dimensional island shape. The active layer growing on the thin film layer also grows in the island shape of a dot shape. The active layer can be readily made to be the quantum well structure or the quantum dot structure excellently. Furthermore, the film thickness of the thin film layer is 50Åor less and very thin.  Therefore, the layer can be readily grown in the island shape in natural formation by the lattice strain energy.

IPC: F02D19/08
Filed: 1981-02-06
Abstract: PURPOSE:To prevent the vapor lock of carburetor by opening the second fuel pipe solenoid valve when the temperature of blended fuel in a float chamber exceeds the specified level in a carburetor which supplies mixed fuel of gasoline and alcohol. CONSTITUTION:During high speed drive, a solenoid valve 26 closes an open-close nozzle 34 by turning a car speed switch 38 off and gasohol or a mixed fuel of gasoline and alcohol is returned to a fuel tank 22 only through a bypass  channel 32. During slow speed driving, the nozzle 34 is opened by turning the car speed switch 38 on and the gasohol is returned to the fuel tank 22. Therefore, the cold gasohol in the fuel tank 22 is supplied to a float chamber 16, preventing a rise in temperature.
