Title: Printed board flow soldering method
Inventor: SHIOTANI HITOSHI
IPC: H05K3/34
Filed: 1991-09-05
Abstract: PURPOSE:To evade imperfect soldering due to residual adhesive agent after a masking tape is used, and enable post-fixing of non-heat-resistant parts in the pre-process of flow soldering process, by performing flow soldering in the state that the mounting portion of the non-heat-resistant parts are covered with a flat box type jig. CONSTITUTION:For flow soldering for electronic parts 2 mounted on a printed board 1, a jig 4 formed in a flat box covering non-heatresistant parts 3 is fixed on the printed board 2 by using screws 5. The whole periphery of end surfaces of the jig 4 closely come into contact with the printed board 1. Even if some gaps exist, solder does not permeate into the inside by the effect of surface tension of solder. Hence the jig 4 can sufficiently cope with warp of the printed board 1 caused by heat. A jig 4a may be integrally unified in a body with a soldering carrier 6 for retaining a printed board 1a when soldering is performed. By the above method, after the non-heat-resistant parts 3 are mounted on the printed boards 1, 1a, said parts are covered with jigs 4, 4a, and then flow soldering for the electronic parts 2 can be performed.

Title: Motor-driven sliding door opening/closing device
Inventor: EMOTO KATSUYA
IPC: B60J5/06
Filed: 1995-08-09
Abstract: PROBLEM TO BE SOLVED: To positively transmit the rotatory-driving force of a driving rubber roller to a rail member by forming a plurality of circular recesses of specific dimensions at the end part of the rail member with which the driving rubber roller with specific diameter and rubber hardness comes in contact when a sliding door is in a totally closed or fully opened state. SOLUTION: A plurality of circular recesses 40 of 3-4mm in bore and 0.5mm or more in depth are formed at the pitch of 5mm or less at the end part of a rail member 11 with which a driving rubber roller 28 of 60mm in diameter with a rubber hardness of 80Hs comes in contact when a sliding door is in a totally closed or fully opened state. As a result, at the time of starting to open/close the sliding door, the contact face of the driving rubber roller deformed being pressed by the rail member 11 successively bites into some of the circular recesses 40 so as to be able to positively transmit rotatory-driving force to the rail member 11. Even with moisture adhering to the rail member 11, opening/closing is not impeded. In addition, the wear of the driving rubber roller is reduced, and no plugging is generated even if rubber and foreign matter enter the circular recesses 40.

IPC: C07C51/487
Filed: 1985-10-09
Abstract: For the selective enrichment with fatty acids, of which the first double bond is in the 6 position, of a starting material containing fatty acids of which the first double bond is in the 6 or 9 position, the starting material is treated with a saturated solution of urea in methanol with predetermined ratios of fatty acids to urea so as to separate the fatty acids, other than the  DELTA 6 polyunsaturated fatty acids in the form of an insoluble inclusion complex.

Abstract: PURPOSE:To increase the power of a laser beam which can be cast with the laser cutting device. CONSTITUTION:This laser cutting device is provided with a nozzle 24 which condenses the laser beam from a laser oscillator 22 by a concave mirror 27 in a machining head 23, irradiates a work 35 with the condensed laser beam and supplies an assist gas to the circumference of an optical axis 37 of the laser beam near the focus of the laser beam. The nozzle 24 has a body 31 which is an annular tubular body and an endless annular slit 36 is formed on the work 35 side surface of the body 31. The assist gas is injected from the slit 36 to an irradiation direction 38 of the laser beam. Then, the machining head 23 is not required any more to have a mechanism for injecting the assist gas coaxially with the optical axis 37. As a result, the need for disposing a condenser lens functioning as a pressure partition and a transmission element in the optical route of the laser beam is eliminated and the use of the concave mirror capable of withstanding large power as a condenser means is made possible. The cutting of the thick work is thus possible.

Filed: 1989-09-01
Abstract: PURPOSE: To separate, for example, a complex protein mixture easily and accurately without gel or dissolved substance being distorted and disturbed by providing a slab gel, a piece-shaped gel solution, and a protection layer. CONSTITUTION: When an upper space is placed at a given position, a piece- shaped gel solution 26 is left and is solidified to a gel. When the gel is fully formed, the spacer is loosened. Then, a protection layer 25 is eliminated itself or is left at the site when it is electrically insulated.

Also, the protection layer 25 is a low-melt-point solid or has a melt point within a range of about 25 deg.C to about 75 deg.C. This kind of material is poured in the form of liquid over an upper edge 24 of a slab gel 23, is cooled, and is solidified before the solution 26 is added.  Once the latter is solidified, a system is heated again and the protection layer 25 is heated again higher than its melt point, and the layer 25 is returned to liquid shape again and is poured or sucked.

Title: Data communication system
Inventor: SAITO MAKOTO
IPC: H04L69/40
Filed: 1991-09-06
Abstract: PURPOSE:To prevent occurrence of dual reception by managing a record number at both a sender side and a receiver side and discriminating the end of transmission or reception. CONSTITUTION:When a fault of a line takes place during data reception at a receiver side and a line is interrupted, all records received so far are aborted and a new record is received and only when all data reception is successful normally, all received records are validated. Moreover, only when all data are normally sent, the transmission is finished at the sender side. The discrimination for the transmission and reception is implemented by managing record numbers at the sender side and the receiver side. Thus, even when a line fault takes place and the communication processing is interrupted, the transmission reception data so far are automatically aborted without notifying the presence of sent or received data, and the reception or transmission is implemented again and occurrence of duplicate reception is prevented.

IPC: H01L29/78
Filed: 1982-12-28
Abstract: PURPOSE:To prevent a thin film device from deforming at the time of forming the device by covering both side surfaces of a low melting point plate glass with insulators having ditortion point higher than those thereof. CONSTITUTION:Since mechanical stress abruptly decreases in the vicinity of the distortion point of glass 11, the glass is readily deformed by thermal stress or mechanical stress. At this time, both side surfaces are strengthened by covering the surfaces with an insulating substance 12 such as SiO2 having strong mechanical strength even in the distortion point of the glass 11 in a thickness of 0.5- 1.0mum. Thus, a thin semiconductor film, an insulating film, and annealing can be formed even at the temperature in the vicinity of the distortion point of the glass 11, and accurately masking can be performed.
