Title: Fuel pump
Inventor: KIYOSE KENZO
IPC: H02K13/00
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To provide a fuel pump capable of preventing a sliding member from being dislocated from a supporting member even if the pump is dipped in fuel. SOLUTION: Wavy recessed and projecting parts are formed on the outer and inner peripheral walls of the bottom 100a side of a carbon base material 100 forming a sliding member which slides with a brush in a circumferential direction alternately, thereby preventing sliding member formed by dividing the carbon base material 100 from being displaced against a support member formed out of resin and supporting the sliding member in the turning direction of a commutator. Natural carbon having anisotropy is pressed in the turning direction of the commutator and sintered to form the carbon base member 100. When the natural carbon having anisotropy is pressed, a swelling rate increases in a pressed direction, and matches with the swelling rate of the resin support member.  It is thus possible to prevent the sliding member from being dislocated from the supporting member in the axial direction of the rotating shaft of the commutator even if the commutator is dipped in fuel and the sliding member and the support member swell.

Title: Original size detector for image forming device
Inventor: KUSUMOTO KEIJI
IPC: G03G15/04
Filed: 1988-01-20
Abstract: PURPOSE:To correctly detect the size of an original by comparing the signal from an optical sensor means with a reference value to discriminate the presence or the absence of the original and storing the counted value of a counter means at the time of switching of the discrimination result from the presence to the absence and discriminating the size of the original in accordance with the last stored counted value. CONSTITUTION:A reference point between an optical sensor means 51 and an original D is detected by a reference point detecting means 50, and the counting operation of the counter means is started at the time of detecting the reference point. A comparing means compares the signal from the optical sensor means 51 with the reference value to discriminate the presence or the absence of the original D, and the counted value of the counter means is stored in a storage means when the discrimination result is switched from the presence to the absence of the original D. That is, the counted value of the counter means is rewritten with the latest value and is stored in the storage means every time when the discrimination result of the comparing means is switched from the presence to the absence of the original D. Thus, the length of the original is correctly detected without being erroneously detected as a shorter value.

Abstract: PURPOSE:To constitute the title method so that creases are not generated on a skin sheet after putting the skin sheet together, by a method wherein a foamable soft layer is formed on the rear of the skin sheet and the soft layer is formed after a pad has been fitted with the skin sheet. CONSTITUTION:A foamable soft layer is formed on the rear of a skin sheet and after a pad has been fitted with the skin sheet, the soft layer is foamed, in a method forming a seat body by fitting the pad, which has been molded beforehand, with the skin sheet.

Title: Optical recording material
Inventor: ITO MASAKI
IPC: G11B7/243
Filed: 1986-01-22
Abstract: PURPOSE:To provide an optical recording material used in an optical recording medium having good signal quality, by having cobalt contained in tellurium. CONSTITUTION:Recording laser beam is condensed to irradiate a recording layer 5 through a substrate 1 to form pits 6. Guide grooves are provided to the substrate so as to record the pits 6 in a concentric circular or spiral pattern at a constant interval with good accuracy. Because it is difficult to form the substrate with guide grooves with good mass productivity, a method wherein the guide grooves are made partially discontinuous to preliminarily record position information is usually taken. Because a position information reading signal can not made large by this method, it is necessary to preliminarily make the unrecorded noise of an optical recording medium. When tellurium is used as the recording layer 5, by having cobalt contained in tellurium, a surface property is made well while high sensitivity is held to reduce unrecorded noise.

Filed: 1987-01-23
Abstract: PURPOSE:To allow the space between a gate electrode and electron gas to be zero with the thickness of a barrier against the electron gas kept constant by providing a heavily-doped N-type semiconductor layer having a forbidden band which continuously varies in the direction of film thickness so that the layer may function both as a gate electrode and as a barrier against electrons. CONSTITUTION:An Al composition x of an AlxGa1-xAs layer 13 continuously varies so that it will be zero in the vicinity of an interface of GaAs layers 12 and 13 as well as in the vicinity of the interface of a gate electrode 14 and x may equal to 0.45 in the vicinity of the center of the layer 13. The layer 13 is heavily doped with a P-type impurity. A valence band end S2 of the layer 13 is almost in agreement with Fermi energy and becomes flat. Further a conduction band end S1 of the layer 13 rises remarkably in the form of angle to form a potential barrier for electrons and the resistance of the layer 13 is low and is in ohmic contact with the gate electrode 14. Thus its layer 13 functions as the gate electrode. In this way, the layer 13 performs two functions as a potential barrier for electrons and as the gate electrode. It allows the space between the electron layer and the gate electrode to be zero and obtains mutual conductance that is two times more than achieved with conventional semiconductor layer.
