Title: Shift register having optical bistable element
Inventor: CHINO TOYOJI
IPC: H01L29/74
Filed: 1993-07-05
Abstract: PURPOSE:To simplify a wiring structure, to integrate plural optical bistable element to a high density and to enable high-speed operation by shifting the light radiated from the optical bistable elements in a light emitting state via optical waveguide means to the other arbitrary optical bistable elements. CONSTITUTION:The plural optical bistable elements are disposed on one n-InP semiconductor substrate 100 and optical waveguide layer 101 consisting of n- InGaAsP is formed on this n-InP semiconductor subtrate 100. The optical waveguide layer 101 is commonly used as an emitter layer of the phototransistors of the respective optical bistable elements. The state of the optical bistable elements changes to the light emitting state in spite of incidence of light of a relatively low set power if the bias voltage to be applied to anode electrodes is increased. The state of the optical bistable elements, therefore, changes to the light emitting state when an extremely high bias voltage is applied to the optical bistable elements. Then, the light emitting state is shifted from the optical bistable elements in the light emitting state to the desired optical bistable elements.

Title: Mass flowmeter
Inventor: KOYAMA TOMIHISA
IPC: G01F1/68
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To correct the temperature drift of flow rate perfectly including the aging by correcting the drift of output due to variation in the characteristic of each component caused by aging through the use of a microcomputer. SOLUTION: When a fluid flows through a duct 10, a current IU flows through the resistance RSU of an upstream sensor while a current ID flows through the resistance RSD of a downstream sensor. At that time, the sensor output voltage VO (VO=RSUIURSDID) is proportional to the mass flow rate of the fluid. The output voltage VO is amplified at an amplifying circuit section 7 and converted at an A/D converting section 12 into a digital signal before being inputted to a microcomputer 11. Terminal voltages of ambient temperature detecting resistances Rtu , Rtd and reference resistances R30u, R30d are also converted into digital signals which are then inputted to the microcomputer 11.  The microcomputer 11 automatically calculates a mass flow rate signal for which drift due to variation in the characteristic of each component caused by aging is corrected through processing based on these input signals.

Abstract: PURPOSE:To prevent ash from being moved in an unmelted state to a discharge port by a method wherein a front bottom wall part on the melting chamber side is formed in the shape of a crest and a rear bottom wall part in the shape of a root. CONSTITUTION:A bottom wall part 5 on the melting side is divided in the moving direction of ash into a front and a rear part. The inclination angle in a longitudinal direction of a rear bottom wall part 5a is set to a range of 0-5 deg. and the inclination angle in a longitudinal direction of a rear bottom wall part 5b to a range of 10-20 deg.. The front bottom wall part is formed in the shape of a crest in the direction (a direction crossing moving direction of ash at right angles) of the width of the front bottom wall part 5a and the rear bottom wall part is the shape of a root in the direction of the width of the rear bottom wall part 5b. This constitution brings molten ash into a uniform state since molten ash is also moved in the direction of width and increases a residing time of ash in a melting chamber.
