Title: Polymer state control agent for pretreatment of non-metal surface for chemical plating
Inventor: CHIYUNNII CHIYAN
IPC: C23C18/20
Filed: 1988-12-23
Abstract: PURPOSE: To facilitate the nucleation on nonmetallic surface and metallic surfaces by using the water-soluble ammonium salt of a di-(hydroxyalkyl)-amine- polycondensate of which the nitrogen atoms are made quaternary at a specific ratio as a state control agent for pretreatment of the metallic surface to be chemically plated.  
     CONSTITUTION: The water-soluble ammonium salt of the di- and/or tri-(hydroxyalkyl)-amine-polycondensate of which the nitrogen atoms are made quaternary up to 10 to 99% by 1 to 12C alkyl groups and/or benzyl groups is used as the state control agent for the pretreatment of the metallic surface. The state control agent is used to pretreat the nonmetallic surface in the form of an aq. soln. of a concn. of 0.001 to 1wt.%. The bath temp. is specified to 10 to 60°C and the application time to 15 seconds to 0 minute. As a result, the nucleation for the subsequent chemical plating is most adequately executed.

Title: Optical module
Inventor: SHIDA MASAYUKI
IPC: G02B6/30
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To provide an optical module with high reliability. SOLUTION: When a waveguide element 2 is fixed with a reference wall 6 for element fixation and two front and rear stoppers 10a and 10b, the fixation position of the waveguide element 2 is restricted, so neither projection from the permissible range of the fixation position nor the breaking of the optical fiber 11 due to vibration is caused, so that the reliability is improved. When the part of the optical fiber 1 where its coating is removed is coated with resin 15, the coating-removed part of the optical fiber 1 is protected, so the optical fiber 1 is never flawed while mounted and the optical fiber is never broken in a proof test, so that the reliability is improved. When the waveguide element 2 is adhered and fixed to a pedestal 16 at a part other than a waveguide array part 8, the waveguide array part 8 is not fixed to the pedestal 16, so stress applied to the pedestal 16 is not applied to the waveguide array part 8 to prevent optical characteristics from varying, thereby improving the reliability.

Title: Positioning pin
Inventor: KOIKE TOSHIFUMI
IPC: B65G47/88
Filed: 1987-12-23
Abstract: PURPOSE:To improve positioning accuracy of an object preventing its bouncing by filling a clearance, formed between a hole drilled in a conveying surface and a positioning pin fitted to this hole, with viscous fluid, in case of the pate- shaped object positioning pin conveyed by pressurized gas. CONSTITUTION:A plate-shaped object 6 is conveyed to the right from the left, when it collides against a pin 3, the pin 3 is displaced to a position as shown by a broken line. Then viscous fluid 5 between the pin 3 and a hole 9 generates force in proportion to a displacement speed of the pin 3 by viscosity of the fluid and its squeeze effect, acting as the damping force for the pin 3. Therefore, impact force of the plate-shaped object 6 is absorbed, and the plate-shaped object 6 is suppressed from its bouncing and reverse returning in the left direction. Next returning the pin 3 to the center of the hole 9 by restoring force of a spring member 4, positioning is performed. Thus preventing the plate-shaped object from its bouncing, the positioning can be accurately attained.

Abstract: PURPOSE: To improve sensitivity and reliability by constituting to obtain a reject limiting value width which encloses an average welding parameter profile based on a selectable probability to the reject of many can bodies which are recognized to be excellent and can bodies itself which are excellent. CONSTITUTION: An average welding parameter profile Fm which is stored in a memory 24 as a first welding parameter profile is obtained. And the average value of the welding parameter value measured to a first welding profile and the product of a standard deviation of the parameter value preliminarily fixed as a normal distribution multiplied by one or more sensitivity coefficients are obtained. Thus, a reject limiting value width which encloses the profile Fm is obtained, and an evaluation for a statistical evaluation of the welding parameter value, wherein the number of existence of can bodies 10 which are judged to be excellent is measured, is executed. Also, whether a second welding parameter profile measured lies within the reject limiting value width to the can bodies 10 which are successively produced is detected by a comparator 26.

Abstract: PURPOSE:To improve the working efficiency of the window display device/ method by preventing such a case where the size of a window WD is changed against the user's will. CONSTITUTION:Plural application programs are prepared for display of each WD. The frame sizes of some WDs can be changed and some of these WDs undergo the updating of their display contents in response to change of the frame sizes. In such a system, it is decided whether the frame size can be changed for each program. If the frame size can be changed, a size change corresponding operation storing part 23 stores the corresponding operation to decide whether the display contents are updated in response to the change of the frame size. Then a WD display control part 22 decides the corresponding operation carried out when the frame size is changed based on the contents of the part 23, after a WD display request is received. Then, the part 22 displays an instruction input part for the size change request with only the change of the frame size and then displays the instruction input part for the size change request that causes the updating of the display contents with the frame size change followed by the updating of the display contents respectively.
