Title: Structure to prevent rattling of gear
Inventor: HAMADA TORU
IPC: F16H3/02
Filed: 1994-11-04
Abstract: PURPOSE: To restrict idle movement of gears, taking advantage of resistance force due to a diameter reducing function, by switching a switching valve, which is in the midst of a connecting passage, which connects an oil pump to the inside of a transmission case, by means of brake oil pressure produced when a controlling means is braked. CONSTITUTION: When the brake is put on, brake oil pressure from a controlling means reaches a connecting part 76 to act on a switching valve 48. In other words, the brake oil pressure slides a piston 64 toward a spring 68, resisting the energizing force of the spring 68, so that a first connecting passage 54 is connected to a brake-time-passage 72. At this time, since the diameter of a second brake-time-passage 72-2 of the brake-time-passage 72 is smaller than that of the first connecting passage 54, resistance force is generated against the force feeding action of the lubricating oil by an oil pump 44. With this contrivance, by utilizing a connecting passage 46, which connects the oil pump 44 to the inside of a transmission case 44, the oil pump 44 can be used as a means to prevent rattling, or an unpleasant noise, of gears.

Filed: 1989-11-13
Abstract: PURPOSE:To obtain an electrostatic lens which is applicable to both wide range analysis and narrow analysis, by composing an electrostatic lens system and installing a switch means to apply voltage to either one of electrodes of the system and ground the other electrode so as to switch the whole lens system to either and expanded projection system or an imaging system in which an intermediate image is formed and reprojected. CONSTITUTION:Lens L has a structure composed with seven cylindrical electrodes L1-L7 arranged longitudinally on one axis and switching the width of analysis range is carried out by switching between voltage application to any of seven electrodes L1-L7 and grounding any of the rest electrodes. Electrodes with odd numbers L1, L3, L5, L7 among seven electrodes always have earth potential and therefore switching is carried out depending on which electrode is energized out of even electrodes or which one of the rest electrodes is grounded. In this way, switching the width of the analysis range is carried out only by switching between an electrode which is grounded and an electrode to which voltage is applied. As a result, an electrostatic lens applicable to both wide range analysis and narrow range analysis can be obtained.
