Filed: 1981-02-27
Abstract: PURPOSE:To perform the centering of a gripper accurately with respect a load axis by fixing a pair of grippers on a flange after the center thereof is connected to the flange through a flexible connecting rod to provide a tension preload. CONSTITUTION:Both ends of a test piece 1 is grasped with a pair of upper and lower grippers 2a and 2b, which are respectively connected to a pair of gripper mounting flanges 4a and 4b through connecting rods 3a and 3b. The connecting rods 3a and 3b herein used shall be a flexible one with a certain strength made of spring steel or the like. Concave sections are provided in the gripper 2a and the flange 4b and low melting point Wood's metals 5a and 5b are housed therein.

Title: Coupling structure of crank and pedal shaft
Inventor: SUGINO YASUSHI
IPC: B62M3/00
Filed: 1993-02-18
Abstract: PURPOSE:To enable a pedal to be easily and quickly assembled by providing a lock coupling projection and a lock recess in such a way as formed at the coupling boundary of a pedal shaft and a crank, and becoming engaged with each other when a coupling body is engaged with the recess. CONSTITUTION:When a pedal shaft 2 is inserted, the oscillation end 40 of an oscillation claw 4 passes a coupling recess 12 and becomes engaged with a coupling recess 13. As a result, the claw 4 is engaged with the vertical wall 130 of the recess 13, due to the energizing force of a spring 42. Thus, the pedal shaft 2 is kept in locked state. Also, when the pedal shaft 2 is inserted to a final position, a coupling projection 21 from the cylinder 201 of the pedal shaft 2 is coupled to the corresponding recess 12 of the crank 1, thereby preventing the relative turning motion of the pedal shaft 2 and the crank 1.

Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To enable to install a trough to be provided below a cooling body for cooling and condensing vapor of treating liquid in a treating tank, at a right position. SOLUTION: A trough supporting member 40 constructed in the shape of a frame is supported on trough receiving seats 50 made of quartz provided projectingly by weld in several places, for example, six places on the inner wall surface of a treating tank 14 at prescribed intervals. On the trough supporting members 40, quartered plate trough 38 (38A, 38B, 38C and 38D) is arranged so that the outer peripheral surfaces thereof is approached the inner peripheral surface of the treating tank 14 as much as possible (for example, 0-0.5 mm). By such construction, since even if there is variance of the dimensional precision of the plate trough pieces 38A, 38B, 38C and 38D, their positioning can be individually performed, installation can be also performed at right position as a whole. Then, a treating liquid fallen to the plate trough 38 from a spiral tube 36 flows down smoothly along the inner wall of the treating tank 14 from a little gap between plate trough 38 and the inner wall surface to prevent it from splashing to the sides of the object to be treated and a saucer 24 and being struck on them.

Title: Loop network monitor and control equipment
Inventor: KAMOSHITA AKIRA
IPC: G06F13/00
Filed: 1991-01-30
Abstract: PURPOSE:To check whether or not double addresses are generated by mistake at the time of the hardware setting of the address of a communication controller when a system is started up. CONSTITUTION:When the system is started up, the monitor and control equipment 11 generates a substitute address transmission request. Communication controllers 12-14 store the addresses of communication controllers which are higher in order than themselves and inform low-order communication controllers 12-14 of their addresses. Thus, the monitor and control equipment 11 can know the addresses in order from the lowest-order communication controller. Then storage address transmission request is resent in order from the highest-order device to the low-order devices. Consequently, the generation of double addresses is detected by receiving reports from communication controllers which do not report their addresses yet.

Title: Modified quickly curable epoxy resin and its production
Inventor: REEMON KEENIHI
IPC: C08G59/14
Filed: 1987-02-14
Abstract: Epoxy resins containing both terminal hydroxyl groups and epoxy-derived groups are prepared by advancing a polyepoxide with a polyol and terminating the reaction at a point such that the epoxy resin reaction product contains both epoxy and terminal hydroxyl groups. The epoxy groups are then further reacted to form epoxy-derived groups and the rate of curing is further improved. The resulting epoxy resins exhibit lower melt and solution viscosities than those exhibited by conventional epoxy resins having the same epoxy equivalent weight, as well as curing quickly when used. The resins are usefully employed at high solids levels in can coating formulations and other epoxy formulations wherein the resin is applied from an organic liquid solution or aqueous dispersion.
