Title: Ball for ballpoint pen
Inventor: NAKATANI YASUNORI
IPC: B43K1/08
Filed: 1998-08-19
Abstract: PROBLEM TO BE SOLVED: To prevent wear of a tip body by removing a bonded metal part between intermetallic compound particles exposed on a surface, and forming a recess at the removed part of the surface. SOLUTION: Hard intermetallic compound particles 17 such as WC or the like are sintered under predetermined sintering conditions, and formed substantially in a spherical shape. This sphere is rolled together with diamond powder between two grinding stones held at a predetermined interval, polished up, and hence its surface 19 is mirror finished. Then, for example, spheres are rubbed together by a barrel, and small pieces of the particles 17 existing between the particles 17 of the surface 19 are removed. Simultaneously, soft bonding metal 18 part of Co or the like is worn and removed, and a recess 2 of an irregular pattern is formed on the removed part. The rubbing together is further continued to remove edge parts of a periphery of the recess 2 of the particles 17 exposed on the surface 19 is removed by colliding the spheres each other, a rounded corner 3 is formed to the ball 1.

Title: Automatic focusing device
Inventor: MARUYAMA TAKESUKE
IPC: G02B7/32
Filed: 1984-11-07
Abstract: PURPOSE:To reduce the titled device at its size by constituting the device of a diaphragm for branching the reflected light of a spot on a subject into plural light beams, prisms and photodetecting elements to detect focused state. CONSTITUTION:Infrared luminous flux 11 radiated from a light emitting part 10 forms a spot on the subject 7 through a condenser lens 12 and lens groups 3, 2, 1, the reflected light is condensed by an image-forming lens 15 through a half mirror 13 and its image is formed on photodetecting parts 18, 19 through the diaphragm 16 and the prism group 17. A motor 24 is driven by a control circuit 22, the lens group 1 is moved and the image of the subject 7 is formed on a sensor 5. The luminous flux divided by the prism 17 is formed an image on the center position of the pphotodetecting parts 18, 19 to detect the focused state. Since a light source part and a range finder are stored in a zoom lens, the device can be reduced at its size and highly accurate focusing can be attained.

Title: Digital copying machine
Inventor: OTANI MASAYUKI
IPC: G03G15/00
Filed: 1990-09-05
Abstract: PURPOSE:To improve speed compared to a conventional sorter and to execute a processing even if the sorter is not connected by sorting and stacking plural jobs by means of changing the direction of a paper through the use of a picture memory. CONSTITUTION:When a sort mode or a stack mode is selected, a control means 205 stores picture information on an original in a storage means 202. When both papers in the both directions of the vertical direction and lateral direction of a selected paper size, stored picture information is read by rotating it by 90 degrees. A vertical original is copied in a lateral paper and a lateral original in a vertical paper. An operation for executing copying in the same paper without rotation is alternately executed at every copy. If the paper size when it is rotated by 90 degrees is larger than a maximum copy possible size, the picture is reduced and it is set within the maximum size so as to set the mode where copying can be executed. Thus, a sorting operation can be realized even if the sorter is not connected.

Title: Ignition circuit for burning device
Inventor: HAYATA YOSHIKI
IPC: F23N5/00
Filed: 1985-10-21
Abstract: PURPOSE:To improve economy with one ignition circuit in common by switching ignition parts with a relay at the ignition operation time in the condition that two burners are integrally controlled by a microcomputer. CONSTITUTION:When a relay 6 for driving electronic ignitor circuit turns ON, the ignitor circuit 1 is actuated to drive a pulse transformer 2 for ignition connected with a switch relay 7 for electric discharge and electricity is discharged at an electric discharge gap. ON and OFF operations of relays 6 and 7 are controlled by a microcomputer. When the two burners are required to ignite simultaneously or one burner is required to ignite while another burner is in ignition operation, priority is given to the ignition operation of a burner for hot-water supply to carry out its ignition operation and during that time, a burner for additional burning is made to stand by in prepurge condition. After the ignition of the burner for hot-water supply is completed, the switch relay is changed over to the additional burning side to turn ON the relay for discharge and put the burner for additional burning in ignition operation.

Title: Production of aromatic aldehyde
Inventor: SOMA YOSHIE
IPC: B01J31/20
Filed: 1987-09-16
Abstract: PURPOSE:To industrially and advantageously produce an aromatic aldehyde, by reacting an aromatic compound with carbon monoxide under ordinary pressure using a carbonyl complex of copper (I) or silver in a super-strong acids as a catalyst. CONSTITUTION:An aromatic compound (e.g. pseudocumene) is reacted with carbon monoxide in the presence of a catalyst consisting of a copper (I) carbonyl complex or silver carbonyl complex in a super-strong acid (especially a hydrogen fluoride-based super-strong acid has advantages in that the resultant product is readily separated and a catalyst layer is reusable after extraction with benzene) without pressurization to afford an aromatic aldehyde (e.g. 2,4,5- trimethylbenzaldehyde). Since the production process can be wholly performed under about ordinary pressure, equipment investment cost and operating cost are remarkably reduced to reduce product cost. Furthermore, purity of the product is increased. The resultant product can be utilized in the field of plastics, coatings, plasticizers, adhesives, dyes, etc.
