Title: Board electric potential detecting circuit and board electric potential generating circuit
Inventor: TAKAI YASUHIRO
IPC: G11C11/408
Filed: 2000-05-24
Abstract: PROBLEM TO BE SOLVED: To provide a board electric potential detecting circuit and a board electric potential generating circuit where, with no process-dependency, a board electric potential is detected and controlled at high precision, a response speed is high, latch-up is prevented, the occupation area of element is suppressed from increasing, and a leak current is suppressed.

The electric potential at a node N4 between the resistor elements 31 and 32 is inputted into one input point (a gate of a transistor 33) of a current mirror circuit 100, while a ground electric potential is applied to the other input point (a gate of a transistor 35). When the board electric potential VBB is equal to a set value, a 0V is applied to the gate of the transistor 33, and, as the board electric potential rises, a voltage higher than 0V is applied to the gate of the transistor 33, so that an output signal of 'high' is outputted from the current mirror circuit thereby, thereby injecting an electric charge into the board for lower board electric potential.

Title: Manufacturing method of semiconductor device
Inventor: NAKAMURA NAOTO
IPC: H01L21/205
Filed: 2000-05-26
Abstract: PROBLEM TO BE SOLVED: To prevent film formation from fluctuating by inhibiting the increase in manufacturing costs. SOLUTION: In the CVD film formation process where a boat 11 that retains a plurality of wafers W is carried into a treatment chamber 4, and a feed gas 21 is supplied into the treatment chamber 4 for forming the wafers W, a group of wafers W are packed and retained at the upstream region of the feed gas of the boat 11 when a smaller number of wafers W than the number of wafers that can be retained in the boat 11 are to be retained in the boat 11. A product wafer and a side dummy wafer are retained at a film formation speed stage region at the upstream side of the boat 11 and the film formation speed unstable region at the downstream side, respectively. Pressure in the treatment chamber 4 is measured by a pressure gauge 10 near a furnace inlet 5. A carrier gas is supplied along with the feed gas.  Since the group of wafers consumes the feed gas that is supplied to the treatment chamber immediately, a film formation speed cannot be affected even if an empty space is formed at the downstream side. And, film formation becomes equivalent to a normal batch even in the case of a batch where the number of wafers to be treated has decreased.

Filed: 2000-06-02
Abstract: PROBLEM TO BE SOLVED: To provide a gas water-heater in which a secondary pressure (an output pressure of a gas proportional valve) of the gas can be appropriately held. SOLUTION: A controller of the gas water-heater 1 selects one from the following three modes, in response to a command from an external terminal 37, that is, (1) a normal mode for varying the opening of the proportional valve corresponding to the magnitude of a load, (2) a forced maximum combustion mode for maximizing the valve opening of the proportional valve in a set range irrespective of the magnitude of the load, (3) a forced minimum combustion mode minimizing the opening irrespective of the magnitude of the load. When a normal communication is cut off between the controller 9 and the terminal 37, the controller 9 automatically selects the normal combustion mode.

A contact segment 6 which holds the electrode 5 elastically while applying a current to it, and a hook 8 which engages the electrode housing 7 with the electrode 5 are installed in the housing 7. When the housing 7 is inserted in an insertion hole 17a of a fixture 17, movement of the hook 8 is locked. If the lamp is broken explosively, the electrode 5 stays in the housing and does not break other components.

Abstract: PROBLEM TO BE SOLVED: To suppress generation of soot by detecting an injection time point and/or an ignition time point in relation to a lambda in a second operating system, in a device having first and second operating systems for directly injecting fuel into a combustion chamber during an intake step and a compression step. SOLUTION: At the time of uniform operation as a first operating system, a throttle valve 11 is partially opened or closed in relation to a desired torque, and fuel is injected into a combustion chamber 4 from an injection valve 9 during an intake step. Swirl flow (overflow) is applied on injected fuel, and is nearly uniformly distributed into the combustion chamber 4. On the other hand, at the time of stratified operation as a second operating system, the throttle valve 11 is largely opened, and fuel is injected from the injection valve 9 into the combustion chamber 4 during the compressed step. At the time of the second operating system operation, an injection timing point and/or an ignition time point are/is detected in relation to a lambda, and is put operation control to use. It is thus possible to reduce fuel consumption, and it is also possible to suppress generation of soot.

Abstract: PROBLEM TO BE SOLVED: To easily design an optimal blade curved surface shape suitable for a use condition. SOLUTION: This method comprises a processing procedure 1 (#1) for constituting a rotary curved surface by rotating a pair of opposite segments on a quadrilateral and plural segments connecting the both segments around an arbitrary straight line, a processing procedure 2 (#2) for constituting a bent curve of a three-dimensional curve for each rotary curve surface, a processing procedure 3 (#3) for rotating the rotary curved surface according to an arbitrary curved segment 1e, a processing procedure 4 (#4) for forming circumferential projecting parts at the curve segment 1e by extending the bent curve to a prescribed direction, and a processing procedure 5 (#5) for constituting a blade curved surface by smoothly connecting the bent curves.  Thus, it is possible to design the blade curved surface with various projecting part shapes while fixing the blade curved surface other than the projecting parts by performing a procedure for additionally forming the shapes of the projecting parts. Therefore, it is possible to consider the influence of only the projecting parts on noise characteristics, or to design a new blade shape with the projecting parts based on the existing blade curved surface.
