Title: Semiconductor integrated circuit device
Inventor: NISHIO YOUJI
IPC: H03K19/08
Filed: 1982-10-29
Abstract: PURPOSE:To obtain a rapid logical circuit with low power consumption by utilizing the merit of CMOS element and bipolar element. CONSTITUTION:When an input 16 is the ''0'' level, a MOS 10 is turned on, the 1st NMOS 11 is turned off and the 1st npn bipolar element 14 is also turned on. On the other hand, the 2nd npn bipolar element 15 is turned off by shorting between the base and emitter through the 3rd NMOS 13 included in a non- saturated area, so that the emitter current of the 1st npn element 14 charges a load and the output 17 is turned to the logical ''1'' level. When the input 16 is turned to ''1'' level on the contrary, the PMOS 10 is turned off and the 1st NMOS 11 is turned on. Therefore, the 1st npn element 14 is turned off because the part between the base and emitter is shorted through the 2nd NMOS 12 included in the non-saturated area, so that current is supplied to the base of the 2nd npn element 15 from the output 17 to turn on the element 15, and the output 17 is reduced to ''0'' level.

Title: Fluid vibration type flow meter element, its manufacture, flow measurable range determining method
Inventor: KUMAGAI MINORU
IPC: G01F1/20
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To easily expand the proportional relation area between flow rate and fluid vibration frequency without improving the shapes of a downstream passage itself and passage inside walls by installing a target at the position having the maximum area where the Strouhal number becomes practically constant. SOLUTION: A target installation base 7 is movably fitted to a target installation groove 8. The installation base 7 is moved to adjust the distance Lj between a target 3 and a nozzle outlet 2b so that the difference becomes the maximum between the Reynolds number Re*1 at the 1/2-change quantity point on the differential curve corresponding to the vicinity of the low-flow rate side terminal of the area H where the Strouhal number St becomes practically constant and the Reynolds number Re*2 at the 1/2-change quantity point on the differential curve corresponding to the vicinity of the high-flow rate side terminal on the relational curve between the Strouhal number St and Reynolds number Re.  Since the distance Lj can be optimized without changing the shapes of a downstream passage 5 and side walls 6a , 6b , the linear relation area between the flow rate and fluid vibration frequency is expanded, and the measurable area can be expanded.

Title: Cathode-ray tube
Inventor: ITATSU MASAKATSU
IPC: H01J9/24
Filed: 1983-10-11
Abstract: PURPOSE:To enable manufacturing control and quality control to be easily performed when a small number of each of various kinds of cathode-ray tube are manufactured by forming a thermoresistant marking agent, which has no possibility of disappearing when the maximum temperature is reached during the manufacturing process of cathode-ray tubes, on the side wall of a screen panel in such a manner as to enable the marking agent to be optically discriminated. CONSTITUTION:A thermoresistant ink agent is prepared by mixing a magnetic material into a coloring frit or a frit agent used as a caking agent. On the side surface of a panel 1, bar codes 2 which can be optically read or marks which can be magnetically read are printed by using the thus prepared ink agent. Since the above printing of marks is generally performed before the process of thermal treatment, the marks intensely adhere to the panel side surface by heating and can not be easily separated mechanically. Accordingly, there is no possibility that the marks become unreadable and there is a great merit in terms of manufacturing control.

Title: Clutch control device for mechanical supercharger
Inventor: NISHIMURA EIJI
IPC: F02B39/12
Filed: 1989-07-20
Abstract: PURPOSE:To suppress generation of a shock, when a clutch is connected, by weakening a connection degree of the clutch, placed in a half-clutch condition, when a condition of decreasing running performance is detected at the time of transfer from an inoperative region to operative region of a supercharger. CONSTITUTION:In an engine 1, a mechanical supercharger 4, driven by an engine output shaft through an electromagnetic clutch 10, is provided in an intake passage 2 and actuated in a predetermined operative region. Here the electromagnetic clutch 10 is controlled to a half-clutch condition by a controller 11 at the time of transfer of the supercharger 4 from its inoperative to operative region. While a signal of the atmospheric pressure, input to the controller from an atmospheric pressure sensor 14, serves as the representative characteristic, when a decrease of running performance of a vehicle is detected, a connection degree of the electromagnetic clutch 10, placed in the half-clutch condition, is weakly controlled. In this way, especially when the running performance of the vehicle is decreased at the time of highland running or the like, a shock is effectively reduced at the time of connecting the electromagnetic clutch 10, and deterioration of a running feeling is prevented.

Filed: 1986-08-12
Abstract: PURPOSE:To form a foil group pattern having an arbitrary shape excellent in durability and solvent resistance on the surface of a base material, by applying specific processing to a polyamide synthetic resin and using the resin as the adhesive of the base material and a foil. CONSTITUTION:A powder of a polyamide synthetic resin is contacted with an ethanol solvent to be semi-dissolved in a sherbet form. This semi-dissolved resin is held so as to be interposed between the release surfaces of release materials such as release papers and the single surface of one release material is placed on a flat surface and a roller is tumbled on the surface of the other release material to press the resin under pressure of about 20kg from the surface thereof. The semi-dissolved resin between the release surfaces is stretched by the repetition of pressing until the thickness thereof becomes about 11.7-25mum to generate random reticulated cracks. After stretching, the upper release material is released to naturally dry the resin. The resin is disrupted from crack parts to form irregular resin thin pieces having various sizes and arbitrary shapes. The thin pieces are arranged on the base material in an arbitrary pattern and foil pieces are scattered thereon and heat-set then allowed to stand until cooled.
