Title: Automatic lead supply method in automatic drawing machine
Inventor: TANAKA KUNIAKI
IPC: B43L13/00
Filed: 1989-11-30
Abstract: PURPOSE:To certainly guide one lead into a lead guide by applying vibration to the lead guide within a lead tank in the vertical direction by utilizing the driving force of a pen head. CONSTITUTION:A pen head 8 is moved to a predetermined lead supply place and a rising and falling drive apparatus 10 is driven at this place to allow a pen holding arm 14 to fall and a pencil pen 16 is allowed to fall to a predetermined level. Next, the pen head 8 is moved to a place where a knock mechanism 16a comes into contact with the lower taper surface 32d of a shutter 32 and reciprocally moved by about 1mm stroke in the direction shown by an arrow and the shutter 32 is rolled around a rotary shaft 34 and a lead tank 26 is reciprocally vibrated and rotated within a horizontal plane in connection with the shutter 32. At this time, a lead guide 28 reciprocally moves between the lower horizontal surface 32a and upper taper surface 32c of the shutter 32 to be vibrated in vertical direction. By this constitution, only one lead 30 within the lead tank 26 is allowed to fall in the lead guide 28. When the pencil pen 16 moves to a lead falling position, the upper end of the lead guide 28 protrudes from the upper surface of the bottom member 26a of the lead tank 26 and the insertion of other lead in the lead guide is prevented.

Title: Method for joining copper plate to ceramic sheet
Inventor: KOUNO YUMIKO
IPC: B23K1/19
Filed: 1990-11-20
Abstract: PURPOSE:To prevent occurrence of defect of conjuction and improve reliability of conjunction by previously subjecting a copper plate to specific heat treatment in non-oxidizing atmosphere when the copper plate is joined to the ceramic plate using an active metal-containing soldering material. CONSTITUTION:A copper plate is previously subjected to heat treatment retained to re-crystallization temperature or above and melting point or below. Then the treated copper plate is joined to a ceramic sheet using an active metal- containing soldering material (e.g. TiH2-containing silver-copper eutectic soldering material). Thereby when the copper plate is heated in joining, re- crystallization or grain growth is not occurred, because recrystallization or grain growth was carried out by previously heat-treating the copper plate. As a result, the copper plate is free from joining defect.

Title: Method for forming ultrafine pattern
Inventor: OKETA MASAAKI
IPC: C03C15/00
Filed: 1987-12-11
Abstract: PURPOSE:To simply enable formation of ultrafine pattern utilizing a well-known thin film process by forming a metal thin film on a substrate surface, removing a metal thin film other than the part corresponding to the desired pattern and immersing the substrate having thin film into an acid. CONSTITUTION:An aluminum thin film 12 is formed on a substrate 11 such as glass or polysilicone resin and other aluminum thin film part other than the desired pattern X left on the thin film 12 is removed by a photo etching. The substrate 11 having the applied thin film 12 is then immersed into an aqueous solution of hydrofluoric acid, sulfuric acid, etc., to release the thin film 12. Namely, part covered by the thin film 12 is rapidly eroded by the aqueous solution because the aluminum thin film 12 works as a catalyst and pattern X is represented. Furthermore although combination of the glass substrate with the hydrofluoric acid is convenient because of having advantage capable of uniformly dissolving the glass surface in an aqueous solution of hydrofluoric acid and simultaneously carrying out also pretreatment of the glass surface, other raw material may be combined.

Abstract: PURPOSE:To arrange an information projection device above a pilot and to view a bright external field image and an optical information image by using a holographic combiner which transmits light from the front to the rear and refracts light from the information projection device to the rear. CONSTITUTION:The holographic combiner 2 is arranged in front of the pilot 1 while slanting forward. A light beam from an external field is transmitted through the holographic combiner 2 from the front to the rear, so the pilot 1 views the scenery of the front external field as it is. The light beam from the information projection device which projects the optical information, on the other hand, is diffracted backward by the holographic combiner 2. Consequently, the pilot views the optical information and the scenery of the external field one over the other. Consequently, the information projection device 3 can be arranged nearby on the head of the pilot 1, which can views the bright optical field over a wide visual field.
