Title: Centering drill
Inventor: TANAKA HIROHISA
IPC: B23B51/00
Filed: 1988-10-07
Abstract: PURPOSE:To improve the roughness of a machined surface, to lengthen drill life and to reduce a considerable amount of mandays and expenses by forming a subrun off part on the side of a cutting edge of a fitting part where a drill fits in a tool holder to prevent the clogging of chips produced by machining. CONSTITUTION:In the case of centering machining made by a center drill whose subrun off parts 4 extending aside from a main run off part 3 for discharging the chips are notchedly formed adjacently on the side of a cutting edge 2 of a fitting part 16 where a centering drill 1 fits in a tool holder 8, the chips discharge outside along the main run off part 3, but remain partly to clog between the main run off part 3 of the centering drill 1 and the tool holder 8. When the clogging chips become more than their specified quantity, the chips are discharged outside along the subrun off part 4 formed in succession to the main run off part 3. Thus the chips can be prevented from entering between the centering drill and a workpiece to keep the roughness of a machined surface of the workpiece constant and to prevent the life of the centering drill from shortening.

Filed: 1986-10-28
Abstract: PURPOSE:To achieve extension of durability of a force blade and reduction of work time by providing a body frame suspensible by wire ropes or the like with gripping cylinder mechanisms for fixing a long material and a cutting cylinder mechanism. CONSTITUTION:After a long material such as a spent neutron counter tube P is fixed by gripping cylinder mechanisms 2, 3, it is pressedly cut by a cutting cylinder mechanism 4 into which pressure water is supplied through a pressure water pipe 40a.

Title: Reflection type liquid crystal device, and electronic device using it
Inventor: OKUMURA OSAMU
IPC: G02F1/1365
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to display a bright and clean color by combining a light absorbing layer with a polarized light separating reflection plate which has a function to reflect or transmit polarized components to the whole range of visible light wavelength. SOLUTION: In a voltage-unimpressed area 8220, natural light 8210 is linearly polarized in a fixed direction by a polarizing plate 8201. And then, the light is twisted in the polarizing direction by a specific angle by a liquid crystal element 8202, and passes through a color filter layer 8200 and a diffuser 8203, reflecting on a polarized light separating reflection plate 8204, being twisted in the polarizing direction by the liquid crystal element 8202 by a fixed angle, and is emitted from a sheet polarizer 8201 as linearly polarized light. Therefore, when no voltage is impressed, incident light is not absorbed by the light absorbing layer 8205 but reflected by the polarized light separating reflection plate 8204, and as a result, a brightly colored display is obtained through a color filter layer 8200.  Further, when a voltage is impressed, the light is absorbed by the light absorbing layer 8205 and a black display is obtained.

Title: System and mechanism for automatically adjusting viscosity of flux
Inventor: ISHIHARA KAORU
IPC: B23K3/00
Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To stabilize the viscosity of a flux and to supply a homogeneous flux by selecting either the execution of squeezing operation at the set frequency of operation by recognizing and judging the conditions of equipment when the feed equipment of the flux is stopped or the execution of initial squeezing operation at the time of the next working after stopping the squeezing operation. SOLUTION: The self-diagnosis of the conditions of the flux feed equipment is executed by external input information from an external input switch, signal of a sensor and the like in an equipment control box 2. When the result of the self-diagnosis is not in a complete stoppage state, by driving a squeezing brade 4 at the set frequency of operation with a driving unit 3, the flux 6 on a squeezing tray 5 is maintained in the homogeneous viscosity. When the result of the self-diagnosis is in the complete stoppage state, the squeezing operation is stopped. At the time of reworking, by executing the initial squeezing operation, the viscosity of the flux 6 is made to coincide with the viscosity at the time of automatic operation.

Abstract: PROBLEM TO BE SOLVED: To prevent multiple feeding by having a feeding roller pair in a feeding means and having a control means for changing pressure force of the feeding roller pair according to number of refed paper by the feeding means. SOLUTION: Jam causes due to lack of carrier force when pressure force of a retard roller 27b shows 320gf-400gf is agreeable feeding, separation force and when the pressure force is 400gf or more, there is a fear for causing multiple feeding. A silicone rubber roller is used for feeding roller pairs 27a, 27b. A pressure spring 28 extends according to increase of diameter of the roller and pressure amount of the retard roller 27b increases. Pressure amount that was 350gf initially increases with number of sheet maternal and it increases to 400gf or more when the number exceeds over 40000. A solenoid 29 is turned OFF when the number reaches 30000 and length force of the pressure spring 28 is weakened. Accordingly, the pressure force of the roller is kept at appropriate value when the number of the sheet material exceeds 80000.
