Patent JP-H01103844-A (JP)
Title: Manufacture of insulator thin film
Inventor: UEDA TETSUYA
IPC: H01L21/31
Filed: 1987-10-16
Abstract: PURPOSE:To prevent damage from inflicting on a semiconductor element and moreover, to deposit a SiN film of a firm film quality on a film, which is deposited on the sidewall parts of a wiring and so on, by a method wherein RF bias power is applied to a substrate and a DC negative bias voltage is chosen within a proper range (-240--360V). CONSTITUTION:A SiN film, which is deposited on the sidewalls of an Al wiring, is strengthened by generating a DC negative bias voltage in a substrate and at the same time, when the bias voltage is dropped to or more than a certain degree, a semiconductor device is affected. There, the deposition of a film is performed by applying a high-frequency electric field setting the DC negative bias voltage to generate in the substrate between -240V and -360V. Thereby, a SiN film of a strong film quality can be manufactured on the film, which is deposited on the sidewalls of the wiring and so on, as the advantage of an ECR plasma CVD method (an electron cyclotron resonance chemical vapor phase deposition method) is applied to practical use.

Title: Copying device
Inventor: UMEDA ARATA
IPC: G03G15/00
Filed: 1988-10-18
Abstract: PURPOSE:To eliminate the need for stating and specifying a normal copying mode that does not require specification on a copying mode specifying paper and to improve operability by setting a mode after a copying mode specified by the copying mode specifying paper read by a reading means is temporarily set to the normal copying mode. CONSTITUTION:The side of a copying machine main body 4 transits a transmission permission signal to a reader 8, and waits for data read by the copying mode specifying paper 51.

Then, the specified copying mode is set in terms of specified conditions. As a result, the need for stating and specifying the normal copying mode that does not require specification on the copying mode specifying paper is eliminated to improve operability.
Patent JP-S61139114-A (JP)
Title: Manufacture of ultrasonic delay line
Inventor: HAYAKAWA DAISHIRO
IPC: H03H3/007
Filed: 1984-12-11
Abstract: PURPOSE:To reduce an unnecessary reflected signal by using a printing screen, whose sectional shape of a printing hole part has minimum dimensions in the position slightly higher than the center in the thickness direction of this hole part and becomes larger in dimension as going from this position toward both ends in the thickness direction, when an unnecessary reflection absorbing material is printed on the side face of a glass delay medium. CONSTITUTION:When an unnecessary reflection absorbing material 9 which attenuates the unnecessary reflection is printed on the side face of a glass delay medium 8, a printing screen 10 is used whose sectional shape of a printing hole part 10a has minimum dimensions in the position slightly higher than the center in the thickness direction of this hole part and has larger dimensions according as going from this position toward both ends in the thickness direction. When this printing screen 10 is used to print the unnecessary reflection absorbing material 9, print finishing as shown in a figure C is attained. That is, the upper part as well as the lower part of the unnecessary reflection absorbing material 9 have less sagging because the printing hole part 10a of the printing screen 10 has the lower part slowly inclined and the upper part of the unnecessary reflection absorbing material 9 is squeezed up when the printing screen 10 is raised. Thus, the unnecessary reflection is reduced, and an ultrasonic delay line excellent in characteristic is obtained.

Abstract: PURPOSE:To prevent atomized fuel droplets from attaching on the wall of a combustion drum and stabilize combustion by a method wherein an atomizing tip of an oscillating element phone of an ultrasonic atomizer is inserted into an opening of a swirler plate. CONSTITUTION:An atomizing tip 3a of an oscillating element phone 3 of an ultrasonic atomizer 1 is inserted into an opening 15 located at the center of a swirler plate 11. Fuel fed into a liquid holding part 5 through a liquid supply pipe 6 is supplied into an atomizing part 3a through a nozzle 7 and atomized into fine droplets by ultrasonic vibration. On the other hand, a large portion of air in an air chamber A is sent into a combustion chamber B through an air path 12 and the remaining portion flows through air holes 17 on the swirler plate 11, is turned into a swirling flow C and sent into the combustion chamber B. The fuel atomized by the ultrasonic atomizer 1 is intermixed with air by the centrifugal force of the swirling flow C and carried into the combustion chamber B. However, since an axial direction air flow D is formed along the inner wall of a combustion drum 10, the atomized droplets is prevented from attaching on the inner wall of the combustion drum 10, and combustion is stabilized.

IPC: F23R3/32
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To burn stably without generating any vibration of combustion even when the flow rates of air and fuel are changed within a wide range, by a method wherein a gas turbine combustor is provided with a plurality of air injection ports, arranged circumferentially on the slanted surface of an annular partitioning wall through a distance and injecting air into the central axial direction of a combustion chamber. SOLUTION: When the flow rate of fuel from a rotary burner 80 is big, fuel injected out of a fuel nozzle 1 is injected into a whirling current 30 formed of the injected air stream 50 of combustion air passing through a rotary vane 2, and combustion is started. However, the flow rate of fuel is big, thereby continuing combustion reaction by the injected air stream 60 of air injection port 11 arranged on a partitioning wall 14, and injected air stream 55 from a pre-mixing combustion burner. Accordingly, strong diffusion flame is formed at the central part of a combustor and stabilized combustion condition can be obtained. When the flow rate of fuel of the rotary burner 80 is small, flame is formed along the injected air stream 60 from an air injection port 11 arranged on the partitioning wall 14, whereby the fluctuation of combustion flame of the rotary burner 80 is restrained.

SOLUTION: On a heat-shrinkable supporting body, a base coating layer containing an adhesive and a pigment, and a heat-sensitive recording layer containing a leuco dye and a developer, are provided in order. The density of the base coating layer is 0.2-1.2, and the application amount of the base coating layer is 10-20 g/m<2> . When the density of the base coating layer exceeds 1.2, or the application amount becomes less than 10 g/m<2> , by a heat energy for a thermal head at the time of recording, curls or unevennesses are generated on a heat-sensitive recording body after the recording. If the application amount exceeds 20 g/m<2> , when being bent, cracks are easy to arise on the heat-sensitive recording layer.  When the density of the base coating layer becomes less than 0.2, the strength of the base coating layer decreases, and there is fear that a uniform heat-sensitive recording layer may not be formed.

Filed: 1991-10-11
Abstract: PURPOSE:To make unnecessary the operation to set a control parameter to an optimum value by detecting the vibration of a response waveform, extracting the feature quantity from the vibration and adjusting the control parameter so that the vibration can be converged based on it. CONSTITUTION:A vibration detecting means 3 monitors a response waveform, that is, the deviation, and when the difference in the previous extreme value, that is, the vibration width is the prescribed level or above and outside the settling band, the vibration is obtained and as such, the number of times is counted. In order to perform the adjusting action of a PID control parameter, a detected output is given to a feature quantity extracting means 4. The feature variable extracting means 4 extracts the vibration cycle and the damping factor from the detected vibration as the feature variable means 5 counts a new PID control parameter based on the vibration cycle and the damping factor and changes the PID control parameter of a PID control means 2 to a new counted PID control parameter. Thus, the optimum PID control parameter is set automatically.
