Title: Stamper and die for molding synthetic resin substrate
Inventor: FUJINAWA HIROYA
IPC: B29C45/37
Filed: 1988-11-15
Abstract: PURPOSE:To improve the outer appearance and transferring property of moldings by providing a to-be-engaged part in an inner peripheral part, the to-be-engaged part projecting further to a rear level than the front of a transferring part and being held by an inner peripheral retainer ring. CONSTITUTION:An inner peripheral retainer ring 21 holds a to-be-engaged part 30 which is projected further to a rear level than the front of a recording face 20C of an inner peripheral part 20A of a stamper 20. The surface of the inner peripheral retainer ring 21 can be set even with the surface of the stamper 20. Since there is no gate formed around the ring 21 at the inner peripheral side of a cavity 19 adjacent to a to-be-transferred part of the molding, a silver or the like kind of improper appearance which would be caused by the heat of a resin when a gate were present can be prevented. Moreover, since no such gate that narrows a flow path only by a head of the ring 21 in a movable core 14 is present, the resin can uniformly flow in a thicknesswise direction of the cavity 19.

Title: Pressure resistance reducing structure of moon pool
Inventor: MIYAZAKI SATOSHI
IPC: B63C11/00
Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To reduce the pressure resistance acting on a moon pool of a ship. SOLUTION: A hull 1 of a ship such as a global depth surveillance ship or the like is provided with a moon pool 2. A pressure-conducting pipe 3 opens its suction port 3i to a rear wall 2B of the moon pool 2, and its supply opening 3o to a front wall 3F. The seawater in a high-pressure zone H near the rear wall 2B is passed through the pressure-conducting pipe 3, and jetted to a low- pressure zone L near the front wall 2F. Whereby the difference between an integrated value of the pressure distribution of the front wall 2F and an integrated value of the pressure distribution of the rear wall 2B is reduced, the pressure drag acting on the moon pool 2 is reduced, and a navigating speed can be improved.

Title: Barrel device for plating
Inventor: HARADA YOSHINOBU
IPC: C25D17/20
Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To enable the arrangement of many electrodes without intruding foreign matters into a plating solution as a driving mechanism is not dipped into the plating solution. SOLUTION: A barrel shaft 18 is supported to a side board 4 so as to be freely rotatable via a bearing 19. An O ring 20 is arranged between the barrel shaft 18 and the side board 4, and the intrusion of a plating solution into a gear box 8 is prevented thereby. When an electrode gear 61 rotates, an electrode 70 on one side face of the electrode gear 70 and an electrode 71 on the other side face are mutually in contact with a brush electrode 70. Thus, when a horizontal barrel 7 rotates, relating to only point electrodes 65 which are arranged at the lower part and opposed to each other, the electric current is flowed to the material to be plated in the horizontal barrel 7 from the electrode 70 or simultaneously from the electrode 71.

IPC: H01M2/16
Filed: 1995-10-11
Abstract: PROBLEM TO BE SOLVED: To make an electrolyte solution holding body at low-cost and provide a low-cost lead-acid battery, by inserting, between two electrode plates, at least one kind among paper containing a water-absorptive polymer or a water- absorptive textile, a non-woven fabric, and a knit fabric. SOLUTION: A separator is manufactured in such a manner that water- absorptive textile, a thermal fusion textile, and a polypropylene are blended, carded, cross-laid, put in adhesion at a hot wind temperature by an air-through method, and thereafter pressed by calender rollers. This separator, in the event of no load, expands by 3.2 times in thickness by sulfuric acid of a specific gravity of 1.2. This is inserted between a negative electrode plate and a positive electrode plate to form an element which is put into a battery jar and sulfuric acid of a specific gravity of 1.2 is poured thereinto. The sulfuric acid is rapidly absorbed in the separator, the separator expands, the sulfuric acid is completely absorbed, and a gap between the electrodes is completely filled up.  As described above, a low-cost lead-acid battery is provided, by using, instead of a glass mat, an electrolyte solution holding body which expands on being pregnated with sulfuric acid in an electrolyte solution of the storage battery.

Title: Movable wall
Inventor: IKEUCHI AKIRA
IPC: E04B2/00
Filed: 1997-10-07
Abstract: PROBLEM TO BE SOLVED: To prevent the bending stress from being applied to a wire. SOLUTION: The movable wall is formed in structure, in which a sealing body installed at the lower end of a wall body moved along a rail in a freely projecting-retreating manner is urged in the direction that the sealing body is projected by a spring and an operating device sinking the sealing body is mounted on the wall body.  The operating device has a wire 17 stretched to the wall body and linked with the sealing body, a rack 26, which is laid on a base 21 fixed onto the wall body in a freely linear-motion manner and to which one tip of the wire 17 is retained, a pinion 29 rotatably supported to the base 21 and engaged with the tooth row 27 of the rack 26, a handle for rotating the pinion 29, and a ratchet 34 being engaged with the tooth row 27 of the rack 26, preventing the motion in the projecting direction of the rack 26 and releasing the preventing state by operation at that time. Accordingly, since the rack 26, to which the wire 17 projecting and retreating the sealing body is retained, conducts only a linear motion, the repeated bending stress applied to the wire 17 can be obviated.

IPC: H01F17/06
Filed: 1997-10-08
Abstract: PROBLEM TO BE SOLVED: To obtain an inductor for a heavy current which ensures the cancellation of magnetic flux leakage and no variation in inductance values. SOLUTION: An inductor comprises a toroidal core 11, which is provided with a gap 13 at a portion thereof for making saturation less likely to be produced, and another core which is arranged in the vicinity of the gap 13. The latter core is provided with a winding 19 so as to generate a magnetic flux in a direction opposite to that of the magnetic flux generated at the toroidal core 11. The winding 19 is connected to a winding 15 of the toroidal core 11 in series, so as to increase the reverse directed magnetic flux, when magnetic flux leakage is increased. Such an effect is further enhanced by having a shielding member arranged at the gap 13.

Therefore, since an ultrasonic vibration is, acting, a plastic material of a stationary side piece 7 side is contracted away irrespective of the stationary side piece 7. Then since plastic material itself also is heated with the ultrasonic vibration, the bottom of the stationary side piece 7 becomes hard to cool. Therefore, a intact form is transferred to parts to be molded, in the top (mirror surface) 18 of a movable side piece 11. With this construction, a molded product where a plane of a high-accuracy optical reflector is molded is taken out from within a cavity 12.

Filed: 1985-12-25
Abstract: PURPOSE:To leaves the execution of a processing unfinished which is useless, namely proved to be unsuccessful, with the program by detecting quickly the failure of the unification of an argument. CONSTITUTION:Data parts are sent through signal lines 611 and 613 to a computer 605. When both tag parts show the constant, a single 615 comes to be 'true', and when the tap parts cannot unify like a list and a constant, a signal 614 comes to be 'true'. When the impossibility of unification is detected by comparing the tap parts only and even when both tag parts show the constant, the data part is not coincident and the impossibility of unification is detected, a signal 617 comes to be 'true'. When the signal 617 comes to be 'true', a unifier B stops the checking of the subsequent argument and sends a signal 619 to request the unification stoppage to a unifier A. The unifier A receives the signal 619, and then, the unification is completed and to program executing control part, a signal 108 of the failure of unification is transmitted.
