Title: Mechanism for controlling center of gravity of high-place working vehicle
Inventor: KISHI MITSUHIRO
IPC: B62D37/04
Filed: 1982-05-13
Abstract: PURPOSE:To prevent the body of a high-place working vehicle from falling over due to the tilting of a boom, by supporting a counterweight on the vehicle body so that the counterweight can be moved depending on the tilted angle of the boom. CONSTITUTION:A vehicle body 4 is rotatably supported on a rotary pedestal 3 on the chassis 1 of a high-place working vehicle. Pairs of horizontal rails 16 are laid at the right and left sides of the vehicle body 4 in the front-to-rear direction of the body so that the rails extend in parallel with a stright line perpendicular to the axis of rotation of a lower boom 6 about a pin 7. Counterweights 17 are movably supported on the rails 16. When pressurized oil is applied to a hydraulic cylinder 14, the oil is also applied to moving cylinders 18 to csuse rods 23 to slide in a direction G to move the counterweights 17 in a direction F on the rails 16 depending on the applied quantity of the pressurized oil. As a result, too much weight does not act to the rear part of the vehicle body 4, so that the center of gravity of the vehicle is not displaced backward. The vehicle is thus prevented from falling over due to the deviation of its center of gravity.

Inventor: INOUE YUICHI
IPC: B60C23/06
Filed: 1993-04-08
Abstract: PURPOSE:To eliminate influence of tire replacement by extracting resonant frequency components from signals including tire vibration frequency components and detecting tire pneumatic state according to this and resonant frequency calculated from the kind of a selected tire. CONSTITUTION:Alternating current signals of pick-up coils 3a-3d of speed sensors of tires 1a-1d are input in ECU4 composed of a waveform formation circuit, ROM, RAM, etc., as well as signals of kind selection switches 6a, 6b of the tires 1a-1d.

Title: Developing method
Inventor: HOSOYA MASAHIRO
IPC: G03G15/08
Filed: 1989-03-31
Abstract: PURPOSE:To always maintain constant image density and to obtain a good- quality image high in density by leaving a part of a thin toner layer on the surface of a toner carrier even after developing a solid image. CONSTITUTION:Even after a large amount of nonmagnetic toner is consumed like after the development of a solid image, a part of a thin nonmagnetic toner layer is allowed to remain on the surface of the toner carrier by rapidly attaching a prescribed amount of toner to the surface. The conveyability of the toner can be remarkably enhanced by this developing method. The triboelectrified charge of the toner itself induces charge reverse in polarity to the toner on the surface of the toner carrier, and the toner is strongly attached to the surface of the carrier by its attraction force, thus permitting the remaining toner to scoop the toner particles of the fresh toner in a toner vessel, and deterioration of the conveyability of the toner to be prevented from deterioration and always uniform and good images high in density to be obtained.
