Patent JP-H06137353-A (JP)
Title: Titanium alloy spring and manufacture thereof
Inventor: TANGE AKIRA
IPC: C25D5/12
Filed: 1992-10-27
Abstract: PURPOSE:To provide a titanium alloy spring having improved wear resistance and freedom from a drop in fatigue strength, and a method for manufacturing the spring by forming a heat conductive layer on a layer of relatively high hardness. CONSTITUTION:The second layer 3 of relatively soft quality having high thermal conduction is formed on the first layer 2 having relatively high hardness enough to ensure wear resistance, thereby enabling the initial wear amount of a titanium alloy spring 1 to be reduced. Also, even if the titanium alloy is exposed due to wear at a later stage, the heat releasing capability thereof can be maintained and seizure can be prevented, thereby enhancing the wear resistance of the spring 1.

Title: Method and machine for measuring-out of roundness
Inventor: SATO EIICHI
IPC: G01B21/30
Filed: 1996-11-08
Abstract: PROBLEM TO BE SOLVED: To inexpensively provide a method by which the out of roundness of a work can be measured in a short time by making the rotating speed of a turntable faster. SOLUTION: When a measuring machine is set to a manual mode (step 31), a clutch is disengaged and a turntable is set to a freely rotatable state (step 32). When a worker manually rotates the turntable (step 33), the rotational position data of the turntable are outputted from a rotary encoder and, at the same time, the rotating speed of the turntable is calculated by using the rotational position data (step 34). When it is confirmed that the rotating speed of the turntable becomes stable within a prescribed range after the turntable is rotated by a prescribed rotational angle or larger (step 35), the fetching of displacement data from a detector is started (step 36) and the out of roundness of a work is calculated from the rotational position data and displacement data (step 38).  Since the out of roundness can be measured by only centering the work without switching the mode of the measuring machine, the measuring machine can efficiently measure many works.

Abstract: PURPOSE: To obtain aq. solution of a colored photosensitive resin composition capable of forming a photosetting film uniform and free from mottle without being affected by an absorption hole of a substrate holder or the like at the time of applying on a substrate to form a pattern of the photosetting film by specifying contact angle of the colored photosensitive resin composition to the substrate so as to be equal to or below a specific angle. CONSTITUTION: The aq. solution of the colored photosensitive resin composition is used for forming the pattern of the photosetting film applied on the substrate, contains a dispersed pigment and has <=50 deg. contact angle to the substrate. As the photosensitive resin of the composition, a photosensitive resin soluble in an organic solvent or water soluble photosensitive resin compound of a photosensitive polymer alone or the combination with a photopolymerizing monomer is used and particularly, the water soluble photosensitive resin is preferable. The adjustment of the contact angle to make <=50 deg. is executed by adjusting the quantity, kind and balance between hydrophilic group and hydrophobic group about a surfactant used as a dispersant of the pigment.

IPC: H01L23/02
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To prevent a liquid sealing compound from flowing deep inside a package by a method wherein each corner part of an opening in a cavity is rounded. SOLUTION: A liquid sealing compound 7 is applied on the peripheral surfaces 1a of an opening in a package main body 3 and after a lid 8 is aligned with the main body 3 on this sealing compound 7, the lid 8 is pressed to the main body 3 to bond to the main body 3 and the sealing compound 7 is solidified. At this time, as the shape of each corner part 9 of an opening in a cavity 2 is formed into one, which has a shape of a radius of about 0.5 to about 10 millimeters or thereabouts, for example, and is made to have a rounding, the wet-spreading area of the sealing compound 7 squeezed out inside the cavity 2 by pressing the lid 8 to the main body 3 is increased and the surface tension of the liquid sealing compound 7 to the inside of the lid 8 and the corner parts 9 of the opening in the cavity 2 is increased.  As a result, the flow of the sealing compound 7 to the corner parts 9 is spread. Thereby, the sealing compound 7 can be prevented from flowing in the cavity 2.
