Title: Automatic analyzer
Inventor: IKEDA TOSHIYUKI
IPC: G01N35/10
Filed: 1992-07-23
Abstract: PURPOSE:To efficiently extract a liquid constituent from a specimen which is separated into the liquid constituent and a solid constituent and then to achieve an automatic analyzer which can detect the amount of the extracted liquid constituent accurately. CONSTITUTION:A control part 61 controls motors 40 and 48 so that a nozzle 41 approaches a specimen container 42 while performing suction operation. When the tip of the nozzle 41 reaches the upper surface of a liquid constituent 43 at a time t1, the signal of a pressure detector 50 increases abruptly. At this time, the descent of the nozzle 41 is stopped temporarily, the nozzle 41 is raised by a certain amount, and a syringe 47 is returned to its original state. While the nozzle 41 and the syringe 47 are lowered from a time t2, the liquid constituent is sucked by the nozzle 41. When the nozzle 41 penetrates a separation agent 44 at a point t3, the signal of a pressure detector 50 increases abruptly. At this point, the descent of the nozzle 41 and the suction by the syringe 47 are stopped. An amount of extracted liquid 56 of the nozzle is accurately calculated by the control part 61 according to the amount of suction operation of the syringe 47 during the period.

Title: Laser welding method of aluminum sheet, manufacture of enclosed cell, and enclosed cell itself
Inventor: OKADA NAOTADA
IPC: B23K26/21
Filed: 1998-07-13
Abstract: PROBLEM TO BE SOLVED: To provide stable laser welding by specifying a thickness at the end face of a sheet and a fusion diameter of the fusion part, with a laser beam emitted, and thereby preventing a crack. SOLUTION: Scanning is performed with a laser beam 3 of a YAG laser generator emitted from the side face of an outer can body 1 towards a weld zone 5 between the outer can body 1 and a cover. The outer can body 1 is hermetically sealed with the cover 2 by means of seam welding that continuously forms a fusion part 4 of the weld zone 5. The weld zone is irradiated in such a manner as the relation of 0<t<d/2 holds between the thickness t of the end face of the cover 2 and the fusion diameter d of the fusion part. The setting conditions of the YAG laser generator is, for example, such that the cycle period is 20-30 Hz, that the pulse width is 3-5 ms, and that the travel speed is 5-10 mm. Further, a nitrogen gas is blown against the weld zone 4, preventing generation of bubbles due to oxidation at the time of welding.

IPC: C08F2/00
Filed: 1981-12-08
Abstract: PURPOSE:To obtain the titled resin having a frosted glass-like appearance, by dissolving a different styrene resin less compatible with a styrene resin in a styrene monomer or a monomer mixture containing a styrene monomer and a vinyl cyanide monomer and polymerizing the solution.

Then, the solution is polymerized by a bulk polymerization method or a bulk-suspension polymerization method. As the above different styrene resin, a copolymer consisting of 10-90wt%, preferably 60-80% styrene monomer residues and the balance of 90-10wt% vinyl cyanide monomer residues, is preferred, and this copolymer is dissolved so as to provide a concentration of 0.1-15wt% (preferably 4-10%).

Title: Metal mold for sealing resin
Inventor: NUMAJIRI KAZUO
IPC: B29C33/40
Filed: 1981-12-08
Abstract: PURPOSE:To prevent resin from sticking to the internal surface of a pot by providing a plunger, through a circumferential ring made of elastic material, in the pot which is interconnected, through a resin supply passage, to a cavity for accommodating an object to be sealed. CONSTITUTION:A resin tablet is thrown in the pot 5 of a metal mold for sealing resin 10 and it is smashed by causing a plunger 6 to descend, and by this, it is possible to push the resin into a cavity wherein an object to be sealed is accommodated quckly by preveting resin from sticking to the internal surface of the pot 5. As a circumferential ring 7 is caused to closely contact with the internal surface of the pot 5, the resin is substantially prevented from sticking to the internal surface, and even if resin is caused to stick to the internal surface of the pot 5 by the plunger 6 as it is pulled up, the amount of resin is very small and it can be easily removed by the scraping action of the circumferential ring 7 when the plunger 6 is made to descend next time.

Title: Neutral position returning device for control valve
Inventor: HAGA MASAKAZU
IPC: F16K31/44
Filed: 1990-07-27
Abstract: PURPOSE:To reliably return a control valve to a neutral position and hold it only by switching a switch valve even when a lever is situated in any position by locating two cylinder structures between the lever and the control valve and controlling pressure oil, fed thereto, by means of the switching valve. CONSTITUTION:When an electromagnetic switch valve 14 is switched to a lower position, the bottom side of a cylinder 7 is connected to the rod side of a cylinder 8, and pistons 7b and 8b and rods 9 and 11 are respectively in a free state. Thus, a direction switching valve 3 is returned to a neutral position through the return force of a spring 3a, and a control lever 4 is brought into a freely controllable state. However, even when the control lever 4 is operated in any manner, no influence is exercised on the direction switching valve 3. As far as the electromagnetic switching valve 14 is situated in a lower position, the neutral position of the direction switching valve 3 is reliably held. This constitution returns the direction switching valve to a neutral position only by switching the electromagnetic switching valve even when the control lever is situated in any position, and holds the control lever.

Title: Composite-type radar sensor
Inventor: SHIRAI TOSHIHITO
IPC: G01S17/87
Filed: 1998-07-14
Abstract: PROBLEM TO BE SOLVED: To enable the detection of a wide range of near and distant objects by scanning an area including an object monitoring area with an optical beam of an optical radar sensor. SOLUTION: An optical beam projected from the light emitting element of a light emitting device 14 is passed through an optical fiber, reflected at a reflector 16, and projected to an outside monitoring space. Then it hits an object and reflected, and the reflected light travels backward approximately in the same path as the projected beam traveled, becomes incident onto the reflector 16, is reflected and guided to the optical fiber, and is received by the light receiving element of a light receiving device 15. Then the reflector 16 is driven to rotate periodically in normal and reverse directions on a rotating shaft 17a via a base 17 by a rotating device 18 in synchronization with the operation of the projection of the optical beam to scan in right and left directions with the optical beam. Therefore, the object monitoring area of the optical radar sensor 13 is not only in a conventional form in an optical axis but is enlarged approximately to the form of a fan. By this, the monitoring area has a wider range than that of a conventional composite-type radar sensor, and reliability in monitoring objects is improved.
