Title: Manufacture of thin film, rotating elliptical body having thin film formed, bulb using it and thin film formation device
Inventor: KOMATA YUJI
IPC: H01K3/00
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To provide a thin film formation method capable of forming a thin film having a uniform thickness on an adhered substrate including a rotating elliptical body shape even when a film formation method wherein film formation particles come flying only in a specific direction like a film formation method by various kinds of deposition methods or sputtering methods is used. SOLUTION: This film formation method forms a thin film on a substrate including a rotating elliptical body shape in film formation particles that come flying in a certain direction from a film formation source, and the thin film is formed by performing spin movement for rotating the substrate at a certain angular velocity centering the rotation axis of the rotative elliptical body shape while simultaneously performing swing movement for rotatively vibrating the substrate at a certain period in the same plane entering the vicinity of the middle point between two focal points of the rotative elliptical body shape on the rotation axis. Thereby, a uniform thin film can be formed in the circumferential direction of the substrate and in the rotation axis direction of the spin movement even if the substrate includes the rotative elliptical body shape.

IPC: G01K11/24
Filed: 1984-05-23
Abstract: PURPOSE:To enable to detect directly the temperature and inflow and filling states of plastics in a mold from the outside of the mold, by making a sine wave oscillate in a pulse state by a ultrasonic oscillator by fixing a ultrasonic vibrator on the outside of the mold. CONSTITUTION:When plastics 3 flows in between molds 1, 2, a probe 5 is fixed to the outside 4 of a mold 1, a sine wave is made to oscillate in a pulse state, which is made to transmit to the molds 1, 2 and plastics 3, a reflected wave being reflected by boundary surfaces 8, 9 is received by the probe 5, amplified by a ultrasonic vibrator 6 and monitored by oscilloscope 7.

Title: Thermal transfer printer
Inventor: AMANO TOSHIAKI
IPC: B41J29/373
Filed: 1985-05-16
Abstract: PURPOSE:To make it possible to effectively erase an erroneous printing part, by method wherein an erasing transfer ribbon is arranged at a recording position at the time of the erasion of erroneous printing and a heat generating part is preheated while a thermal head is returned to the previous position from an erronous printing position and heat generating capacity is increased to lift off an erroneous printing part. CONSTITUTION:When erroneous printing was generated, the rotation of a ribbon selector 14 is controlled to hold a cassette 5 to an inclined state. In this state, an erasing transfer ribbon 7 is opposed to the heat generating part of a thermal head 4 to fuse and adhere the heat-sensitive adhesive resin on the erasing transfer ribbon 7 to an erroneous printing part by the heat generated from the thermal head 4 and the erroneous printing part is released after cooling to be erased. Because a larger heat generating capacity is generally required in erasion as compared with recording, the voltage supplied to each resistance heat generating element of the thermal head 4 is controlled so as to be raised as compared with that supplied at a usual recording time. When the erroneous printing part is lifted off, the thermal head 4 is returned to a predetermined position but, during this time, the heat generating part is preheated.

Title: Production of sintered and forged parts
IPC: B22F5/00
Filed: 1992-03-31
Abstract: PURPOSE:To provide the process for production of the sintered and forged parts which can minimize plastic deformation and can easily separate these parts to two. CONSTITUTION:The mechanical characteristics (density, C, Cu contents, etc.) near the breaking part of a molding W1 (W2) in the process for production of the sintered and forged parts including respective stages for powder mixing, premolding, sintering, forging, cooling and separating are varied from the characteristics in the other parts and the molding W1 is broken and separated at the temp. lower than a brittle fracture initiation temp. The impact value of metallic materials in general increases in proportion to their density and inverse proportion to their C and Cu contents. Then, the impact value near the breaking part of the molding W1 (W2) before the sepn. by breaking decreases locally if the density near the above-mentioned breaking part is previously made smaller than the density of the other parts or if the C and Cu contents are previously enriched and, therefore, the molding W2 is easily plastically broken in the breaking part simply by applying small energy thereto. The molding is separated to the two parts (connecting rod body 15A and bearing cover 15B). The plastic deformation of the molding W2 at the time of the is thus minimized.
