Title: Thin-film pattern forming method
Inventor: HAZUKI RIYOUICHI
IPC: H01L21/027
Filed: 1991-03-30
Abstract: PURPOSE:To process a thin film composed mainly of copper by a dry etching method and to easily form a fine wiring pattern and the like. CONSTITUTION:In a thin-film pattern formation method, a thin film 12 which has been formed on a semiconductor substrate 11 where an element has been formed and which is composed mainly of copper is processed to a desired pattern by a dry etching method. At the thin-film pattern formation method, a mask material film 13 composed of at least one out of TaC, WC, SiC, BC, TaN, WN and BN is formed on the thin film 12. The mask material film 13 is etched selectively to a desired pattern; then, the surface of the substrate is heated to, e.g. 250 deg.C or higher; and the thin film 12 is etched selectively by making use of the mask material film 13 as a mask by using a dry etching method using a reactive gas which contains chlorine atoms.

Title: Hopper
Inventor: FUERAARI ROORENTSUO
IPC: B65D88/28
Filed: 1989-03-18
Abstract: PURPOSE: To speed up and improve efficiency of filling to a tube by letting a triple-ridged container have mutually facing long and narrow walls bent inward nearly in parabola, forming a feeder opening consisting of a long and narrow slot at the lower end and resiliently mounting the container to an elastic supporting device. CONSTITUTION: A container 1 is of an irregular triple ridge shape with a rectangular upper end. The container 1 has long and narrow sidewalls 2 and 2a bent inward like a bow. The bowlike sidewalls 2 and 2a disposed to oppose each other form a long and narrow outlet 3 at the lower end. The outlet 3 has a slot shape. The bowlike shape of sidewalls is convenient for avoiding separation of pulverulent components supplied through the hopper installed at an upper part as well as for flowing materials vertically toward the outlet. The front wall 1b is equipped with a well-known vibrator 4 with variable frequency. The container 1 has been mounted on an elastic member. This elastic member has such structure and disposition that the hopper vibrates in an elliptic orbit lengthwise. Namely, it has been so designed as to vibrate the hopper in the running direction of the open tube 5.

Title: Heat roll fixing device
Inventor: KAMOGAWA JINICHI
IPC: G03G15/20
Filed: 1987-03-20
Abstract: PURPOSE:To shorten the rise time to suppress the overshoot phenomenon of the surface of a heat roll by allowing a peak part of the temperature distribution in the axial direction of the roll to occur in middle parts between end parts of the roll and the center part and providing a detector for control in the part where the temperature is highest at the rise time. CONSTITUTION:Light distribution of an infrared lamp to a roll 1 is so designed that the surface temperature of the roll 1 at the rise time is maximum in middle parts (f) and (h) between a center part (g) and end parts (e) and (i) of the roll, and a temperature control detector 7 is provided in the part where the temperature is maximum on the surface of this heat roll. Since the temperature of the part (g) is lower as shown by D (temperature of parts (e) and (f) are lower also) when the temperature of the part (f) on the surface of the roll reaches a point C, heat is diffused from the part (f) to parts (g) and (e) through constituting materials of the roll to suppress the overshoot. Heat is smoothly and quickly transmitted to the whole of the roll to not only reduce the power consumption but also accurately control the temperature.

IPC: B65H7/06
Filed: 1990-03-17
Abstract: PURPOSE:To detect a jam at a place on a carrying passage where installation of a sensor is difficult physically by providing an up-down-counter for counting-up in the upstream of a place to be detected and counting-down in the downstream of the place to be detected. CONSTITUTION:When a paper sheet carried to a photoelectric switch 1 normally is heaped at a place A on a carrying passage 3, the paper sheet never arrives a photoelectric switch 2, and the count-down signal is not generated from a count-down control unit 8. Consequently, only the count-up signal by the photoelectric switch 1 is output, and when a count value of an up-down-counter unit 6 is amplified to exceed a set value, the jam signal is output from a comparing unit 7. At this time, in the case where the paper sheet arrives at the photoelectric switch 2 without passing the photoelectric switch 1 because of a failure of carrying or the foreign material such as a broken piece of the paper sheet or the like is mixed in from a space between the photoelectric switch 1 and the photoelectric switch 2, this counter unit 6 is drifted in the minus direction.

IPC: H01H33/91
Filed: 1989-03-20
Abstract: PURPOSE:To improve breakability by installing a connecting portion to connect a driving rod with a buffer cylinder at the side opposed to an insulating nozzle of the buffer cylinder. CONSTITUTION:There are no connecting portions of a buffer cylinder 10, and a buffer room 9 communicates directly to a discharge path 12; and a connecting portion 20 is installed at the side opposed to the insulating nozzle of the cylinder 10. When an driving rod 8 is driven to the right at the breaking time, a piston 17 moves to the left referring to the cylinder 10, and the insulating gas in the buffer room 9 is sprayed to an arc 19 through the discharge path 12. As there are no connecting portions between the buffer room 9 and the discharge path 12, the insulating gas in the buffer room 9 moves to the desiccate path 12 without any resistance. No pressure loss occurs therefore, so that it is possible to spray high pressure insulating gas directly to the arc with the result that the portability is high.
