Title: Air-fuel ratio controlling method of internal-combustion engine
Inventor: WATAYA SEISHI
IPC: F02D41/00
Filed: 1984-02-27
Abstract: PURPOSE:To prevent a wrong, substantial compensation due to getting air mixed in fuel from being performed, by forbidding any memory of a learning value of air-fuel ratio compensation into a random access memory at a time when a residual quantity of fuel inside a fuel tank is below the specified value. CONSTITUTION:A controller 8 controls an air-fuel ratio so as to make it come to a theoretical air-fuel ratio on the basis of an output signal out of an air-fuel ratio sensor 10. However, if there are errors in an air flow meter 3 or an injector 2, a feedback integration factor shifts from the central value so that this shift value is stored in a random access memory 83 as a learning value whereby a fundamental fuel injection quantity is compensated. But, when a residual quantity of fuel inside a fuel tank 11 runs low and thereby air comes to be mixed in, compensation by a large learning value is carried out. And, under this condition, if fuel is fed, the air-fuel ratio grows large and shifts to the rich side so that when the fuel residual quantity is below the specified value, any memory of the learning value into the random access memory 83 is forbidden with a signal out of a fuel gauge 14.

When such an arrangement is employed, only a toner 21 having properties suitable for image formation in a region facing the gate 29 is selected by adjusting the ON time and used for image formation. Since a toner sorting means is not required additionally, only a good toner 21 can be used surely for image formation without causing any cost increase. Although a shield electrode 39 is employed in the embodiment, only a ring-like electrode 27 may be employed in another embodiment.

Title: Semiconductor device
Inventor: YAMADA TAKASHI
IPC: H01L27/108
Filed: 1994-03-09
Abstract: PURPOSE:To enable memory cell structure which can secure enough capacity even for the further reduction of the occupied are a of a memory cell by interposing a pad electrode consisting of a conductor layer whose height from an electrode is made higher than a storage node electrode. CONSTITUTION:A bit line 14 is made in the layer above a capacitor, and besides the bit line 14 is connected to the other of source or drain regions 6a and 6b through a pad electrode 10P being shelved up to the upper side of a storage electrode 10. Since the pad electrode 10P higher than the storage electrode 10 is made this way, even if the capacitor is made higher, a pad electrode 10P further higher than it can be made. Hereby, the retreat of the plate at processing of a plate electrode can be advanced not only in lateral direction but also in vertical direction, so the processing keeping such a margin that it is separated enough from the bit line contact area and that it does not expose the adjacent storage node electrode 10 can be performed.

Title: Fully automatic washing machine
Inventor: MATSUDA EIJI
IPC: D06F17/10
Filed: 1995-02-27
Abstract: PURPOSE: To make it possible to lessen the friction of clothing to the wall surface of a dehydrating tank of a fully automatic washing machine which dries the clothing by the operation of a blasting means while applying centrifugal force on the clothing by rotating a pulsator and to efficiently agitate the clothing by increasing the bore of the dehydrating tank upward to a taper shape. CONSTITUTION: The clothing tends to be kicked off outside when the centrifugal force is applied on the clothing by rotating the pulsator 26 by the driving force of a driving motor 27 after the end of washing, rinsing and dehydrating strokes, but the wash is kicked upward of the dehydrating tank 21 along the slope 25 of the pulsator 26. As a result, the clothing is agitated and is dried evenly by the air for drying generated by the blasting means 28. The clothing kicked up by the centrifugal force at this time moves upward while maintaining the contact with the wall surface of the dehydrating tank 21 but the contact resistance of the clothing with the dehydrating tank 21 is lowered and the clothing is made to be kicked up much higher by forming dehydrating tank 21 to the bore of the tapered shape gradually widened toward the upper direction. The agitating effect is thus enhanced.

Title: Printing head apparatus
Inventor: MORIMURA HISAO
IPC: B41J2/275
Filed: 1988-02-22
Abstract: PURPOSE:To prevent the positional shift of a printing caused by abrasion, by forming a plurality of printing actuators, which are individually driven by an electromagnet part, and a spring means for returning each of the actuators to the original position from the same leaf spring material. CONSTITUTION:A plunger 8 composed of a ferromagnetic body is mounted to one end of each of actuators 7a and a printing pin 9 is mounted to the other end thereof. Herein, since the actuators 7a and spring means 7b, 7c for returning the actuators to the original positions are formed of the same leaf spring material 7, the actuators 7a are set to the state supported by the spring means 76, 7c and, since the motion of the actuators 7a receives only the elastic deformation of the spring means 7b, 7c, it is prevented that friction is generated at a revolving fulcrum by the revolving motion of the actuators. Since the extremely short printing pin 9 is used, a structure not requiring a member such as a wire guide is obtained. Therefore, the positional shift of a printing part generated by friction with the elapse of time can be effectively prevented.

Title: Electrodeposition coating method
Inventor: HANIYUUDA KAZUHISA
IPC: C25D13/00
Filed: 1980-03-26
Abstract: PURPOSE: To paint the substrate uniformly by conducting electricity to the substrate immersed in electrodeposition paint and oscillating the substrate.  
     CONSTITUTION: The substrate 3 is suspended by means of a suspension jig 5 moving in an arrow direction on a track 4 and is entered into a tank filled with electrodeposition paint 2 consisting essentially of a water-base synthetic resin. After the entire part of the substrate 2 is immersed into the paint 2, electricity is conducted to the substrate 3, whereby it is painted. In this case, the suspension jig 5 during painting is oscillated to the right and left, by which the substrate 3 is oscillated in the paint 2. As a result, disturbance is given to the paint 2 by the oscillation of the substrate 3, and air having formed air pockets on the painting surface of the substrate 3 is expelled by the liquid resistance based on this. The painting surface of the substrate 3 is contacted approximately uniformly with the paint 2 by this, whereby the substrate 3 having virtually no uncoated painting surface parts is obtained.
