Title: Mixture ratio controller for carburetor
Inventor: TAKAMARU TAKESHI
IPC: F02M7/24
Filed: 1982-02-26
Abstract: PURPOSE:To attain a wide range of mixture ratio control, by utilizing the fact that the mixture ratio of a carburetor changes in its entire operating region and the time of operation of actuators at a threshold value lengthens when the density of the air changes and by detecting the ratio between the operation times and shifting the mixture ratio of the whole carburetor by a predetermined value. CONSTITUTION:The concentration of O2 in exhaust gas is detected by an O2 sensor 2. The signal of the detection is applied to a control circuit 3. When the ratio of mixture is not equal to a prescribed value, the control circuit 3 calculates a necessary quantity of modification to send a control signal to actuators 4A, 4B. The actuators 4A, 4B are turned on and off depending on the control signal to supply a carburetor 5 with air necessary to keep the prescribed mixture ratio. An auxiliary actuator 6 is connected to the main fuel line of the carburetor 5 through an additional passage 55. When the prescribed mixture ratio cannot be achieved only by the operation of the actuators 4A, 4B, as under the change in the atmospheric pressure caused by that in the altitude, the auxiliary actuator 6 is operated according to an instruction from the control circuit to attain the prescribed mixture ratio.

Title: Formation of thin noble metal film
Inventor: UCHIDA SHINICHI
IPC: C23C14/06
Filed: 1994-02-02
Abstract: PURPOSE:To form a thin noble metal film on a substrate with superior adhesion by forming a thin film, composed of the same material as the undermentioned substrate, on this substrate and then continuously forming thin noble metal films, at the time of forming a thin noble metal film on a heat resisting insulating substrate. CONSTITUTION:At the time of forming a thin film of noble metal (gold, silver, platinum, etc.) on a heat resisting insulating substrate (alumina, aluminum nitride, etc.), first a thin film composed of the same material as the substrate and having about 10-500nm film thickness is formed on the substrate under vacuum conditions by an electron beam vapor deposition method, etc. Subsequently, by the same film forming method in the same equipment kept in vacuum, thin noble metal films are formed on the thin heat resisting film until required film thickness is reached. Because the thin heat resisting film, directly after film formation, is in an activated state, the thin noble metal film can be formed with high adhesion.

Title: Nonvolatile semiconductor memory device
Inventor: TERADA YASUSHI
IPC: H01L27/115
Filed: 1991-01-28
Abstract: PURPOSE:To reduce the operation delay regardless of a threshold in an inverter by supplying the output in an internal step-down circuit to a loading transistor and reading the information in a memory cell by using a differential amplitude circuit. CONSTITUTION:When the address signal from an outside is changed, a sense amplifier circuit 35 is initialized, the bit line is reset to the earth potential and loading transistors TR 31-33 are activated. Also when the threshold in the selected TR is high, the potential in a node N is boosted and when it is low, the earth potential is held in the earth potential. While, on the side of reference, the potential in a node N2 is inverted at the potential in a node N1 and the output in an inverter 36 is also inverted. Thus, the reduction of the operation delay is made regardless of the threshold in the inverter by providing the bit line with constant potential providing an internal step-down circuit 30 and by detecting potential change in the node N1 with the circuit 35.

Title: Speed detector
Inventor: GOTOU MAKOTO
IPC: G01P3/481
Filed: 1979-03-14
Abstract: PURPOSE: To obtain a speed detector of a high performance which is not adversely affected by the eccentricity of a detection rotor, by detecting the difference in time between detected signals from two detectors disposed adjacent to each other.  
     CONSTITUTION: AC signals are generated in detectors 6, 7 while a detection rotor 2 is rotated. Since the detector 6 is positioned on the upstream side in the direction of rotation of the rotor 2 with respect to the detector 7, time difference T occurs between detected signals from the detectors 6, 7. These signals are converted to corresponding pulse signals by pulse formers 11, 12. When these AC signals are changed from a negative state to a positive state, pulses are generated. A pulse signal formed on the basis of an output signal from the detector 6 is input into a saw-tooth wave form generator 13 to produce a saw-tooth wave form signal the wave form of which starts at an instance of generation of the pulse signal. This signal is input into a sample holder 14, and the signal is subjected to sampling when a pulse based on an output from the detector 7 is generated. The sample voltage is held and sent to an output terminal 9. This voltage corresponds to the time difference T. Thus, the speed of rotation of the rotor 2 can be detected.

Title: Sewage treating apparatus
Inventor: MORI NAOMICHI
IPC: B01J19/32
Filed: 1979-03-14
Abstract: PURPOSE:To make it possible to treat sewage stably for a long period of time by a method wherein a filler material layer arranged within a purifying tank is constituted from a freely extensible and contractible material and, by changing a sewage flow passage structure, the growth and the exfoliation of a biological membrane adhered to a filler material layer are carried out in turn. CONSTITUTION:A freely extensible and contractible filler material layer 3 is formed by adhering a synthetic resin corrugated plate or by forming a cut out portion in a synthetic resin flat plate and inlaying respectively at right angle in an opposedly contact manner to form a square pillar like flow passage. If the purifying operation of sewage is carried out by using this filler material layer, firstly, a biological membrane adhered to this filler material layer 3 starts the proliferation and the thickening gradually. But, when the lowering of purifying efficiency according to the thicknening of the biological membrane does not advance remarkably, if a handle 5 is rotated, a filler material layer 3 is totally contracted and the cross area of a  sewage recirculating circuit formed in a filler material layer 3 is reduced. Therefore,  the recirculating speed of sewage passing through the filler material layer 3 becomes  larger to release the adhered and thickened biological membrane and, because the  structure of a filler material layer 3 is changed, can be released mechanically.
