IPC: B41J2/335
Filed: 1989-09-06
Abstract: PURPOSE:To obtain a thermal head which has excellent wear resistance and thermal shock resistance by a method wherein for a wear resistant layer, silicon carbide is used, and the component ratio between C and Si for the silicon carbide is continuously or discontinuously changed in the thickness direction of the wear resistant layer so that the component ratio at a heating resisting body side becomes minimum. CONSTITUTION:On an earthing electrode 12, a substrate 1 is placed, and from a gas inducing port 10a, a mixed gas which is composed of C2H4 as a hydrocarbon gas and SiH4 as a hydrogen silicide gas is induced in a decompression chamber 10 while the mixing ratio of the mixed gas is being changed. When a prescribed voltage is applied to an electrode 11, carbon C and silicon Si in the hydrocarbon gas and hydrogen silicide gas which have been excited by the applied voltage adhere to the substrate 1 in accordance with a mixed component ratio y/x, and on the surface of this substrate 1, a wear resistant layer 6, which is composed of SixCy, is formed. For example, the component ratio at a heating resisting body 3 side is taken as y/x=0.6, and the y/x value is gradually made larger in the thickness direction of the wear resistant layer 6, and at the surface, it is made to be y/x=2.8.

Title: Mold structure and connector structure
Inventor: OTA TAKASHI
IPC: B29C33/12
Filed: 1996-09-03
Abstract: PROBLEM TO BE SOLVED: To deal with the dimensional irregularities of parts mounted on a board by forming the tip parts of an upper side connector clamping part and a lower side connector clamping part to be sharply angled and setting the tip parts so that thay are pressed into contact with or bite into the outer peripheral edge part of a connector respectively when an upper mold and a lower mold are clamped together. SOLUTION: The tip parts of connector clamping parts 22, 27 of an upper mold 20 and a lower mold 25 are formed to be sharply angled. When the upper mold 20 and the lower mold 25 are clamped, the interval between the tip parts 24, 28 of the connector clamping parts 22, 27 is set to the smallest size, within a tolerance, of a connector 12. Therefore, the connector clamping parts 22, 27 are kept in contact with each other, even when the connector 12 is of the smallest size. On the other hand, when the connector 12 is of the largest size, the tip parts 24, 28 of the connector clamping parts 22, 27 are pressed into contact with or bite into the outer peripheral edge part of the connector 12, so that the irregularities of the size, within a tolerance, of the connector 12 can be dealt with.  Thus it is possible to prevent a defect such as the leakage of a packing member from a parting line 23 between the upper mold 20 and the lower mold 25 and a contact face between the tip parts 24, 28 of the connector clamping parts 22, 27 and the connector 12 from occurring.

Title: Optical disk substrate
Inventor: HORIE TAKAHIRO
IPC: G11B7/2533
Filed: 1986-09-30
Abstract: PURPOSE:To eliminate the warpage by optical distortion and moisture absorption and to provide a substrate having high surface hardness and heat resistance by photosetting a specific polymerizable compd. and specific resin compsn. to a prescribed shape. CONSTITUTION:A: The polymerizable compd. expressed by the formula 1 and B: The resin compsn. consisting of an acrylate monomer, oligomer and vinyl- contg. monomer are photoset to form the optical disk substrate. The components A, B are used by being mixed. The mixing ratio thereof varies with the respective kinds and amts. to be used; the substrate is brittle and the impact resistance thereof tends to degrade if the ratio of the component A exceeds 50wt%. The hydroscopicity is large and the heat resistance and surface hardness tend to degrade if said ratio is below 5%. The properties vary with the structure and number of the functional groups of the components themselves as regards the respective components of the component B and, therefore, the ratio thereof cannot be unequivocally determined; the use of >=50% is more preferable.

Filed: 1992-08-08
Abstract: PURPOSE:To uniformize the load as a whole of an operating cycle by miniaturizing a driving mechanism and utilizing an excess force of the driving mechanism in a return stroke time of a pressing plate. CONSTITUTION:A driving mechanism swinging and driving a pressing plate 2 i5 continuously attached at a lower part of the pressing plate 2 as one body, and supported with a driving mechanism supporting body 7 extending to an almost horizontal direction by putting a pivot-attaching part 3 between them, and an end part of a rotary arm 13 attached to an output shaft 12 of the driving mechanism is connected with a fixing pivot-attaching part 15 fixed to a box body 1 side through a connecting rod 14. In such a way, because the driving mechanism of the pressing plate is supported with the driving mechanism supporting body 7 extending almost horizontally, the rotary moment is added based on the gravity of the driving mechanism by making the pivot-attaching part 3 as the fulcrum in the compression stroke time of the pressing plate, so the driving mechanism itself's outputting power can be made enough even if it is small so much.

Filed: 1989-09-08
Abstract: PURPOSE:To attain the attenuation of a standing waves being a cause of spurious impedance characteristic of a surface acoustic wave resonator by coating a sound absorbing agent to an end of a reflecting electrode located to a side opposite to a drive electrode. CONSTITUTION:A sound absorbing agent 9 is coated to an end of a reflecting electrode 3 located to a side opposite to a drive electrode 2. That is, an ultrasonic wave in the mode conversion exists under the drive electrode 2 and the reflecting electrode 3, the energy confinement between the reflecting electrodes is impossible for the ultrasonic wave and the ultrasonic wave is reflected at the end of the reflecting electrode 3 forming a mismatching termination and the end of a piezoelectric substrate 1, resulting that the ultrasonic wave is superimposed on the main vibration mode and a spurious radiation is caused in the impedance characteristic. Then the sound absorbing agent 9 is coated to the end of the reflecting electrode 3 on which the ultrasonic wave is reflected causing the spurious radiation. Thus, the sound absorbing agent 9 attenuates the ultrasonic wave and the spurious radiation appearing at the impedance characteristic is suppressed.
