Title: Oscillation wave motor
Inventor: MAENO TAKASHI
IPC: H01L41/09
Filed: 1990-04-02
Abstract: PURPOSE:To drive a motor stably by setting the ratio of length between the linear section and the arched section of a resilient body at a specific value. CONSTITUTION:When an elliptical resilient body comprises an arched section and a linear section having different rigidity, two standing waves formed in the resilient body have different inherent modes and vibrations. Inherent vibrations under two modes are matched to each other by matching the ratio between the distorsion energy causing inherent vibration and the vibration energy even if the two standing waves, symmetrical to the axes l1, l2, have nodes of different shape. The shape is varied such that the ratio between the generalized rigidity and the generalized mass, which is proportional to the square of the ratio between the sum of the distortion energy and the amplitude, will be constant.

Title: Liquid crystal display device
Inventor: TAKAHASHI SUSUMU
IPC: G02F1/1335
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device of low price having high brightness and high display quality with low consumption of electric power by providing a light source means with a lens layer which guides the light from a light source to a liquid crystal panel and further providing with a light-shielding portion having openings near the focal plane of the lens layer. SOLUTION: The light scattered by the scattering reflection pattern 82 or the like outgoes from the upper face of a light-transmitting plate 79. A lens layer 15 consisting of a plurality of lenses is disposed on the exiting side of the light, and a light-shielding layer 18 having openings corresponding to the respective lenses is disposed near the focal plane of the lenses constituting the lens layer 15. The light outgoing from the light-transmitting plate 79 passes only through the openings of the light-shielding layer 18 to enter the lens layer 15. Since the light-shielding layer 18 is disposed near the focus, the light outgoing from one point of the light-shielding layer 18 outgoes as changed as a light beam in a certain direction by the lens from the lens layer 15.  The direction of the light outgoing from the lens layer 15 can be determined by the size of the opening of the light-shielding layer 18. Namely, with the smaller (larger) the opening size of the light-shielding layer 18 is, the more (less) the directional property of the back light shows.

Abstract: PURPOSE:To obtain high capacity while suppressing deterioration in voltage characteristics, by soaking a porous material into raw-material salt solution of an active material and then performing electrolytic reduction in alkaline solution and electrifying the solution so that the processes of charging and discharging the active material are repeated several times. CONSTITUTION:A nickel sintered porous material is soaked into cadmium nitrate solution, and then drawn out to perform electrolytic reduction with a nickel plate serving as an opposite electrode in alkaline solution. An active mterial is charged and discharged by electrification in the alkaline solution. Those processes are repeated several times to form an anode plate for an alkaline storage battery. Then, highly reactive metalline cadmium generated by electrolytic reduction is oxidized by electrification prior to the following impregnating operation, to obtain cadmium hydroxide high in stabilization. There fore, high- density metalline cadmium enables impregnation of the active material to be kept, capable of obtaining the high-capacity anode plate while suppressing deterioration in voltage characteristics.

Title: Method and apparatus for operating condition surveillance of drill-shaped tool
Inventor: KAWAI SUMIO
IPC: B23Q17/09
Filed: 1979-07-13
Abstract: PURPOSE:To permit the given length of the tool to be sensed in machining by sensing the pressure fluctuation produced by the operation of a selector valve comprising a tool holder mounted on a rotating main spindle and a valve means sliding inside the holder. CONSTITUTION:When the tool holder 2 is mounted on the main spindle 1, an outer cylinder 18 is fixed to a quill, and compressed air is supplied for an air passage port through a coupling seat 36. When a machining command causes the main spindle 1 to move forward and a drill 7 to contact with a workpiece at a position a, a channel 9 of a valve means 8 connects air passages 12 and 11 together and a pressure switch connected to the passage 11 at a given feeding position (position b) of the main spindle 1 confirms the normality of the drill 7. When the bit of the drill 7 is worn and goes beyond the normal cutting region (position c) due to the increased thrust, channels 12 and 13 are made to connect with each other, and this permits the pressure switch connected to the air passage 11 to detect an abnormality until the valve means 8 contacts with the stop portion.

Title: Roll chock for rolling mill
Inventor: HONJIYOU HISASHI
IPC: B21B31/02
Filed: 1979-07-14
Abstract: PURPOSE: To absorb the deformation of the rolling roll, to prevent the breakage of the coupling sleeve, and to integrate the handling of both roll chocks, by forming the stopper and the protuberance respectively at the confronting parts of the inside roll chock and the outside roll chock, and by connecting two roll chocks with the coupling sleeve.  
     CONSTITUTION: The inside roll chock 4 and the outside roll chock 5 are arranged on the same central axis, and are connected by the coupling sleeve 6 leaving a suitable clearance between two roll chocks 4, 5. The conical bowl type stopper 9 and the conical protuberance 10 are formed respectively at the confronting parts of the inside roll chock 4 and the outside roll chock 5. Hereby, even if the rolling roll 1 causes a deformation, this deformation of the rolling roll 1 is absorbed because of the existance of the clearance between two roll chocks 4, 5, and because the coupling sleeve 6 causes a deformation. If the deformation of the rolling roll 1 is large, the bottom of the stopper 9 collides with the apex of the protuberance 10 of the outside roll chock 5; hereby, the confronting parts engage with each other and the  positional relation of two roll chocks 4, 5, is restricted. Morever, at exchanging,  etc., the bearings 2, 3, the roll chocks 4, 5, can be handled as an integrated one  body, because these roll chocks 4, 5, are connected by the coupling sleeve 6.
