Title: Mouth guard composite
Inventor: UJI TOSHIYASU
IPC: C08L67/04
Filed: 1989-04-07
Abstract: PURPOSE:To obtain a mouth guard composite having physical properties for protecting teeth and jawbone and excellent in installation feeling and durability by comprising ethylene vinyl acetate copolymer and a thermoplastic polycaprolactone having a specified molecular weight. CONSTITUTION:A mouth guard composite consists of a component in which a thermoplastic polycaprolactone showing a softening temperature of about 60 deg.C and generally having an average molecular weight of 10000-100000 is combined with ethylene-vinyl acetate copolymer or a mixture of ethylene-vinyl acetate copolymer with polyvinyl acetate. To make the best use of characteristics of the thermoplastic polycaprolactone, protect teeth and a jawbone and obtain a suitable softening operation temperature, at least 4.0wt.% of the thermoplastic polycaprolactone is required. At less than 4.0wt.%, it is difficult to reduce the softening temperature to lower than 80 deg.C, and the adhesion to fingers can not be improved. At above 50wt.%, the toughness is improved, the softening point is lowered, and the viscosity is lost, the elasticity is reduced to increase hardness, so that the protection of the teeth and jaw bone is made difficult. A quantity not exceeding 50.0wt.% is suitable.

Title: Vibration-isolating rubber supporter
Inventor: YUASA TAKASHI
IPC: E01D19/04
Filed: 1990-04-03
Abstract: PURPOSE:To raise the isolating effect of vibration by a method in which a rubber supporter consisting of a rubber layer, a lower metal plate, and an upper metal plate is slidably set between a base plate fixed to the lower structure and a sole plate fixed to the bridge girder. CONSTITUTION:In case where a bridge girder 7 and a sole plate 8 fixed to the girder 7 are moved to the axial direction of bridge by earthquake, the upper metal plate 3 of a rubber supporter 4 and a base plate 6 are coupled with each other in such a way as to prevent the relative movement of them to the axial direction of bridge through a coupler 11 for preventing the movement of the upper metal plate. The plate 8 moves in a sliding manner in relation to the metal plate 3. The lower metal plate 2 is pressed to the axial direction of bridge through a press projection 9 by the press projection 10 of the plate 8 and moved in a sliding manner by a distance equal to the plate 8. A shearing deformation occurs in the rubber layer 1 by an amount equal to the moving amount of the plate 8. The vibration of the bridge girder can thus be effectively damped.

Title: Torque detector
Inventor: MIZOGUCHI HIROYUKI
IPC: G01L3/00
Filed: 1979-07-10
Abstract: PURPOSE: To make it possible to sense torque fluctuation of an operating axis through no slip ring, by providing a torque transfer plate on the same axis as a driving gear through a flat spring to detect slippage of the rotation phase between the driving gear and the torque transfer plate dependent upon fluctuation of torque.  
     CONSTITUTION: Operating axis is fitted rotatably to driving gear 3 of motor 1. Torque transfer plate 5 is fixed to axis 4. Gear 3 and plate 5 are connected to fitting pins 7 and 8 through curved spring 6. Consequently, torque of gear 3 is transferred  to axis 4 through spring 6 and transfer plate 5. Microswitch S is provided independently. By this constitution, spring 6 strikes switch S with a form curved when  no load is applied to axis 4. When the load is applied to axis 4, spring 6 expands,  and plate 5 is rotated to move to position A', and relative positions of gear 3 and  plate 5 are changed to open switch S. As a result, fluctuation of torque can be  sensed without slip ring.

Title: Thermoelectric conversion device
Inventor: SENDA TAKAO
IPC: H01L35/32
Filed: 1987-04-10
Abstract: PURPOSE:To prevent a peeling phenomenon on an adhesive boundary surface and mechanical damage, etc., by fixing a plurality of thermoelectric transducers through brazing through connecting pieces, both surfaces of which have metallic members, holding insulating layers, and exposing only side faces in narrow surface areas of the insulating layers in the areas of the irreducible minimum of a demand. CONSTITUTION:Thermoelectric transducers 4a, 4b consisting of a p-type and n-type semiconductors are connected in series by connecting pieces 13. These connectors are held by a pair of metallic plates 11, 12, and each abutting section is brazed. Consequently, since there are metallic members so as to coat approximately the whole surfaces of insulating layers 13a on the insulating layers 13a, the insulating layers 13a are not brought into contact with an outside atmosphere. The connecting pieces 13 including the insulating layers 13a are cut in the size of the irreducible minimum of a demand. The thermoelectric transducers 4a, 4b are connected in series while being mutually separated by the connecting pieces 13. Accordingly, the thermoelectric transducers are hardly affected by environmental conditions such as a high temperature, high humidity, rapid heating, quenching, etc.

Title: Positioning device in machine tool
Inventor: NAKAYAMA TAKEO
IPC: G05B19/18
Filed: 1982-05-25
Abstract: PURPOSE:To improve positioning speed and accuracy in an above-captioned device for controlling a machine tool by the difference between command and feedback pulses, by resetting an error counter to zero in the instant of contacting a tool with a workpiece to stop a table and repositioning the table on the basis of contents at a time just prior to the contact and the number of invalidated command pulse. CONSTITUTION:An error counter 60 is reset to zero through a reset circuit 70 by a detected output S1 of a tool-workpiece contact detector 52. As a result, a table 10 is stopped by a drive amplifier 26, and a content E at a time just prior to contact of a tool with a workpiece is latched at 68, and the number K of command pulse invalidated at the zero reset is counted by an over-output counter 74. Then, the contents E and K of the latch circuit 68 and the over-output counter 75 are read to be subtracted from the total number of output pulse, so as to precisely decide an actual contact position for use as repositioning data. With this constitution, although the table is moved at a high speed, it is stopped in the instant of contact of the tool with the workpiece, thereby obviating overrun of the table and achieving precise positioning operation.
