Title: Spindle mechanism of machine tool
Inventor: OKAMOTO MASAHIRO
IPC: B23Q11/00
Filed: 1985-05-22
Abstract: PURPOSE:To prevent the work surface of a workpiece and hearings from respective failure in accuracy and rigidity and seizure due to temperature rising by making the body section inside of both the ends of the bearing mechanism of a spindle out of lower thermal expansion coefficient glass and a spindle head and the bearing mechanism out of low thermal expansion coefficient cost iron. CONSTITUTION:Neoceram used as material for a spindle body section 31 being extremely small in comparison with conventionally used irony material in a thermal expansion coefficient, the thermal displacement of the lower end of the body section 31 in relation to thrust bearing sections 22b and 23a determining the axial directional position of the body section 31 becomes extremely small. And the LE cast irony used as material for a spindle head 12 and bearing metals 21 thru 23 supported by a bed through column 11 is so small in comparison with ordinary cost iron or gun metal in a thermal expansion coefficient that the thermal displacement of the thrust bearing sections 22b and 23a in relation to the bed is also small. Even if the temperature of a spindle 30 is raised due to the rotation, therefore, the thermal displacement in relation to the bed of the lower end of the body section 31 to which a grinding wheel G is attached becomes extremely small preventing a workpiece W from failling the accuracy of the work surface.

Abstract: PURPOSE: To prevent powder and granular material from being stagnated and dust contained in gas to be treated is deposited in both the end parts of a flow passage between inclined plates. CONSTITUTION: A louver has a pair of sidewalls 27 which are arranged opposite to each other and between which a moving bed of powder and granular material is formed, and plural inclined plates 51 which are arranged parallel to each other at a fixed angle between the sidewalls 27 and are fixed to the sidewalls 27 at both the ends. In corner parts 55 in contact with the sidewalls 27 of the inclined plates 51, stagnation preventing surfaces are formed.

Since the powder and granular material are not stagnated in both the end parts AR4 in a flow passage between the inclined plates 51, dust contained in the gas to be treated is prevented from being stuck and deposited on the inclined plates 51, the sidewalls 27 and the like.

Title: Sense amplifier for sram and latching circuit
Inventor: DEBITSUDO PII DEIMARUKO
IPC: G11C11/419
Filed: 1993-04-15
Abstract: PURPOSE: To prevent a SRAM from lowering in reading performance and being delayed in reading after an electric power reduction by providing the SRAM with a sense amplifier and a latch circuit. CONSTITUTION: P-channel transistors(Tr) 50 and 52 are used for a sense amplifier 20, and nodes 16 and 18 are set to a logically high level in a common mode via Tr 74 and 76 during an off-read cycle. A clock signal CLK of logical 0 enables the Tr 74 and 76, and pulls up the nodes 16 and 18 to a positive power source potential VDD, for example, 0 volt. Thus, a zero differential is obtained by setting an intermediate difference signal to a well-known balanced voltage level. A delay caused by the amplifier 20 is determined by the voltage levels of the nodes 16 and 18 at the time of starting read cycle. When a sense amplifier 14 is lowered in the power, the nodes 16 and 18 drift toward the potential VDD in the Tr 42 and 48, but the node can swiftly be driven to the potential VDD by enabling the Tr 74 and 76.

Abstract: PURPOSE:To measure microscopic displacement and inclination, confirming a measuring point,  by projecting a visible light beam for confirming a measuring point, and a measuring light beam,  on the surface to be measurd, by an optical fiber, and photodetecting a reflected ray by an  optical fiber which has been placed adjacently. CONSTITUTION:A light beam is projected from a projecting optical fiber 6, and a reflected ray  from a surface 8 is detected by a photodetecting optical fiber 10. The quantity of light which has been reflected by a shaded portion in the figure increases linearly up to a distance d3 where the  short diameter (l) is < the diameter D of the fiber, and after that, decreases linearly. In this  case, an optical fiber consisting of 3 layers is formed by use of glass whose refractive index is  smaller gradually toward the outside from the center. To the center layer is projected a visible  light beam for confirming a measuring point, and to an intermediate layer 12 is made incident a  measuring light beam. A reflected ray from a ringlike part on th surface 8 is detected by an  outside layer 14, and is photoelectrically converted. In case when the detected value is different  in each part, inclination of the surface 8 is shown, and in case when it is equal, displacement of  the surface 8 is shown, by said value. In this way, microscopic displacement and microscopic inclination are measured, confirming the measuring point.

Abstract: PURPOSE:To prevent control hunting and improve driving performance on a low friction coefficient road by giving very large clutch tightening force at the time of the wheel spinning motion of driving wheels directly connected to an engine, generated ahead of four-wheel spinning. CONSTITUTION:For the driving system directly connected to an engine to one side of front and rear wheels, a torque distribution clutch (a) which changes engine driving power by the tightening force control from the outside is provided on the way to the driving system to the other side of the front and rear wheels.

At the time of the wheel spinning motion of the driving wheels directly connected to the engine, much larger tightening force command value than the tightening force command value according to the difference in the rotational speed between front and rear wheels is outputted to the torque distribution clutch (a) from a driving power distribution control means (d). It is thus possible to prevent control hunching and improve driving performance on a low friction coefficient road.
