Title: Presence and absence decision system for electric parts
Inventor: TERUYA YOSHIHIRO
IPC: H05K13/08
Filed: 1985-05-21
Abstract: PURPOSE:To detect accurately an electric component even when it is mounted slantingly by determining the inclination permissible range of electric components by a detection system which detects electric components on a printed board by a light cutting method. CONSTITUTION:Slit light is projected on a capacitor on the printed board, its image is photographed by a TV camera, and image data is inputted to an inspecting circuit from a image memory 12. An X address counter 10 is driven to count up and when the image data is larger than a slice level 1, an amplifier 22 with a gate is opened. Then, it is decided that the image is a base wire when an X address is smaller than a level 2a or the head of the capacitor when the address is larger than a level 2b. Further, when the image data is smaller than a slice level 3, it is considered that the capacitor can not be detected because it slants. Said operation is repeated while an Y address counter 11 is driven to count up successively, scanning the entire inclination permissible range F. If there is the base material wire in the range F and the head of the capacitor is present in its middle, it is decided that there is the capacitor.

Abstract: PURPOSE:To prevent the generation of a higher order resonance and a buckling phenomenon of a track spring by providing a turning part for moving a track, and using a metallic shaft and a bearing of an artificial jewel for its turning supporting part, in an actuator which follows the focus and track directions in accordance with the rotation of an optical disk. CONSTITUTION:When a current flows to a focus coil 13, a driving force is generated in the upper and lower directions by a magnetic flux generated by magnetic circuits 21, 22, the driving force is transferred to an objective lens holder 12, and it is supported by a focus spring 15 and vibrated in the upper and lower directions. The focus spring 15 is constituted of two pairs of upper and lower parallel plates, therefore, an objective lens 11 is vibrated by coinciding roughly with an optical axis generated from an optical system. When a current flows to a track coil 13, a driving force is generated in the track direction by a magnetic flux generated by the magnetic circuits 21, 22, the driving force is transferred to the objective lens holder 12, and it is brought to a rotary reciprocating movement centering around a shaft 17. Also, a bearing 19 is made of an artificial jewel, therefore, rotated with small friction.

Title: Anti-noise pad for disc brake
Inventor: OKAMURA HIROMASA
IPC: F16D65/00
Filed: 1977-09-09
Abstract: PURPOSE: To suppress the occurrence of noises, by varying the density of a friction member in almost one direction of rotation of disc rotor from one side.  
     CONSTITUTION: The friction member 2 has integrated friction parts 2aW2e different in hardness and juxtaposed in the direction A of rotation of disc rotor. The hardness of the friction member 2 is decreased in stages from the leading side toward the trailing side (rightward in Fig.). The surface pressure is reduced from the leading side toward the trailing side because of the compressibility variation of the friction member 2 in the directin of rotation of disc rotor. The stick slip on the friction surface, which is one of the causes for the noises, is made unlikely to occur. The noises are effectively suppressed from occurring

Filed: 1984-05-31
Abstract: PURPOSE:To provide pour point depressing activity and to improve the durability by depositing nickel, molybdenum, etc. on a carrier consisting of an alumina-titania composite oxide to form the heavy oil reforming catalyst. CONSTITUTION:A catalyst component consisting of Ni, Co, Mo, and W and contg. 3-10wt% NiO, 3-10wt% CoO, 10-30wt% MoO3 and 10-30wt% WO3 is deposited on a carrier consisting of a composite oxide contg. 10-90wt% Al2O3 and 10-90wt% TiO2 to obtain the heavy oil reforming catalyst. Although the obtained catalyst has the same denitrifying and desulfurizing performance as conventional catalysts using a carrier consisting only of gamma-Al2O3, the dewaxing performance of the catalyst can be remarkably promoted in addition to said performances. Besides, the alumina-titania composite oxide is hardly poisoned by nitrogen, and hence provided with durability.

Title: Blow-molded container
Inventor: BUSUJIMA MAKOTO
IPC: B29L22/00
Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To suppress an influence to be inflicted by the shrinkage over time of a bottom part to the bottom sealed part of a blow-molded plastic container which is peeled after lamination, and harden and stabilize the contact-bonding of the bottom sealed part and further increase the contact-bonding strength of the bottom sealed part, according to necessity. SOLUTION: A bottom sealed part 12 molded in a protruding stip shape of the blow-molded plastic container which is peeled after lamination is constructed of a main part bottom rib 14 with a thick wall and a leg rib 17 with a thin wall which forms a connection part to a bottom wall 9. The leg rib 17 hinders the fluidity of a material during molding, so that the bottom sealed part 12 is molded in such a state that a sufficiently high pressing force is caused to act upon the bottom sealed part 12. Consequently, the outer layer 2 and the inner layer 3 of the bottom sealed part 12 are contact-bonded forcefully and thereby the influence to be caused by the shrinkage over time of the bottom part is prevented from spreading in such a direction that the development of bottom cracks is promoted.

Title: Image area dividing method
Inventor: FURUKUBO YOSHITAKA
IPC: H04N19/00
Filed: 1994-04-25
Abstract: PURPOSE:To efficiently divide an edge area by performing the dividing processing of edge and texture areas in an image signal while using a threshold value deciding method considering the features of an attention area. CONSTITUTION:Concerning the image area dividing method for dividing an input image signal (DD0) into the edge area and the other area excepting for that edge area, a threshold value T (DD6) for dividing it into the edge area and the other area excepting for that edge area is adaptively changed corresponding to the statistical feature amount of peripheral picture elements. Namely, when dividing the edge area in the image signal (DD0), a method for varying the thresholdvalue T(DD6) while considering the feature amount showing the characteristics of the attention area is used in place of a method for performing the dividing processing while using a fixed threshold value. Thus, the edge area at a contour line part and the edge area in a texture can be surely and efficiently divided.

Filed: 1981-07-15
Abstract: PURPOSE:To obtain a quartz oscillator which has high adhesive strength and, high reliability and stability, by performing adhesion by a thermal press-contacting method and an ultrasonic welding method. CONSTITUTION:A head part 2 which is heated by an electric heater 12 from below and supported by an ultrasonic welding horn 11 through a supporting line 1 from above is oscillated by an ultrasonic wave while applied with pressure. Consequently, oscillation energy and heat energy, and further press-contacting energy are applied at the same time between the aluminum layer 2a of the head part 2 and the electrode aluminum layer 3 of a quarts blank plate 4 to weld both the aluminum layers together. Thus, a thermal press-contacting and an ultrasonic welding method are both employed, so high adhesive strength and high reliability and stability which can not be obtained by a single method are given to a quartz oscillator.

Abstract: PURPOSE:To prevent production of dews at the antenna seal part of a magnetron by continuing current feed to a magnetron heater even at the time of heating with radiative heat. CONSTITUTION:When a toaster function is selected, heaters 8, 8 are fed with current by shutting a main switch 11 and a relay switch 12, and also the primary coil 9a of a transformer is fed with current, but the power supply circuit 15 of a magnetron 4 remains out of operation because a relay 16 is opened. However, a voltage is induced on a low-voltage secondary coil 9c, so that a magnetron heater 4a is fed with current even at this time to cause heating of the cathode of magnetron 4 and further an antenna seal part 7, and thus their temps. will rise. This prevents production of dews at the antenna seal part 7 even in case the vapor of the object to be heated in a heating chamber 2 reaches the antenna seal part 7.
