Title: Paper feeder for printer
Inventor: KUZUTANI SUSUMU
IPC: B41J13/10
Filed: 1982-11-20
Abstract: PURPOSE:To eliminate the breakage of print paper and other troubles by such an arrangement wherein after a sheet of paper supplied from a paper feeder is once drawn into a printer, the paper feeder is caused to rotate in reverse direction and the rear end of the paper is guided into a paper passage which does not couple with a feed roller. CONSTITUTION:As the paper inserting key of a typewriter 1 is operated, the uppermost sheet of paper 4a on a paper stacker 3 is sent in the direction of an arrow A and it is guided so that it pushes a projection 31a away and wraps around a platen 10. As a sensor 36 detects the front edge of the paper 4a, the transmission of motive power to a feeder roller 5 is stopped and after that the paper 4a is fed by the platen 10 and a drawn-out roller 26. As the rear end of the paper 4a is detected by the sensor 36, a motor for feeding paper is caused to rotate in reverse direction, and the paper 4a is moved in the direction of an arrow B. At this time, the rear end of the paper 4a is prevented from moving in the direction of the feeder roller 5 by the projection 31a, and the paper 4a is guided into a paper passage 35 in the direction of the arrow B, as shown by two-dot chain lines.

Title: High speed semiconductor device
Inventor: IMAMURA KENICHI
IPC: H01L29/20
Filed: 1985-09-18
Abstract: PURPOSE:To facilitate utilization of a two-dimensional electron gas layer as a base and avoid increase of a base resistance even if a current amplification factor hFE is increased by making the base layer thinner by giving some alternation to the composition of respective semiconductor layers in an HET. CONSTITUTION:An emitter layer 12 is provided on the substrate 11 side of a base layer 14, which is made to be very thin, and a collector layer 16 is provided above the base layer 14. Barrier layers 13 and 15 are doped with an N-type impurity and serve as carrier supplying layers as well and a two-dimensional carrier gas layer 20 is formed in the base layer 14. As the emitter layer 12 does not exist directly under a base electrode 18, even if an ohmic contact between the base electrode 18 and the two-dimensional carrier gas layer 20 is formed, an alloy region 21 and the emitter layer 12 are not contacted with each other. As the collector side barrier-carrier supplying layer 15 is sufficiently thicker compared to the emitter side barrier-carrier supplying layer 13, the dielectric strength between the emitter and the collector is sufficiently high. Moreover, when the layers are to be scraped off by etching, it is not required to provide highly strict control of the etching.

Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To easily impart an oxide single crystal with nonlinear optical effect in high reproducibility by substituting B for a part of Al or Ga of BaAl2 O4 or BaGa2 O4 . SOLUTION: This oxide single crystal has a structure obtained by substituting a part of M of a composition of BaM2 O4 (M is Al and/or Ga) with B and has an asymmetrical center around the B atom to impart the crystal with a nonlinear optical effect. In this case, the single crystal preferably has a composition expressed by the formula Ba(M1-x Bx )2 O4 (M is Al and/or Ga; 0.001<x<0.15). The single crystal can be produced by melting a raw material, having a composition of BaM2 O4 together with B and growing a single crystal containing B substituting for a part of M. The growing can be performed by a pull-up method or a floating zone melting method.

Title: Snow discharger to snow trench using pipe
Inventor: ISOBE KINJI
IPC: E01H5/09
Filed: 1986-08-29
Abstract: PURPOSE:To effectively remove snow on narrow roads by using a working vehicle by which the mixture of snow and water in a stirred tank housing snow and water from the snow trench is sent out to the snow trench. CONSTITUTION:As a working vehicle 6 runs, snowfall is cut by the screw shaft 16a of an auger cutter 16 and charged through a conveyer 17 into a stirring tank 19. On the other hand, water is sucked through a suction tube 2 and a hose 7 from a snow flow trench 1 by a water pump 13 and sent to the tank 19 where snow is finely crushed and mixed with water by rotation of an impeller 20. The snow-water mixture is sent out by a discharge pump 14 and discharged to the trench 1 through a hose 8 and a discharge tube 3. Snow on narrow roads can thus be effectively removed because the needs for snow- carrying vehicles other than the working vehicle can be eliminated.

Title: Air/fuel ratio control device for spark-ignition type internal combustion engine
Inventor: NISHIMURA AKIHIRO
IPC: F02D41/14
Filed: 1992-07-07
Abstract: PURPOSE:To eliminate affection by variation in load to make a stable air/fuel ratio control by providing a rotational speed detecting means and a comparison means to compare a particular frequency component taken out from a faulty component detecting means and output a control signal. CONSTITUTION:A voltage signal corresponding to the number of rotations is detected by a speed detecting means A. From it, a particular frequency component which becomes especially large when an engine burns unstably is taken out by a faulty component detecting means B. A comparator means C compares the magnitude of the taken-out particular frequency component with a reference value, and outputs a control signal to reduce a difference between them. An air/fuel ratio adjusting means D operates according to the control signal. Also a load detecting means E to detect a load on the engine to correct the operating condition of the air/fuel ratio adjusting means D according to the detected load. Thus the device can cope with a fault resulting in variation in rotational speed which differs from that in normal condition, and the engine can be operated while an air/fuel ratio is controlled properly.
