Abstract: PURPOSE: To improve the vertical rigidity of a piston by making the clearance between connections as to the axial direction of a pair of pin bosses, at the connection to connect the outer peripheral surface of the pin bosses housing a piston pin to the inner peripheral surface of a skirt part of the piston. CONSTITUTION: A piston 1 formed a recess 3a on the top surface has a pair of pin bosses 4a and 4b to house a piston pin. The pin bosses 4a and 4b are arranged on the peripheral surface of the piston 1 separating each other in the common axis M-M direction, and they are connected to the inner peripheral surface of the pistonn skirt part 6 through each corresponding connections 5a and 5b on the outer peripheral surface. In this case, when the clearance between the connections 5a and 5b is represented by WC, and the width of the recess 3a, that is the diameter of the outer peripheral edge of the recess 3a, is represented by WD, the connections 5a and 5b are formed as WC<WD. Consequently, the rigidity of the piston 1 in the direction vertical to the axis M-M is improved.

Abstract: PURPOSE:To enable response at high speed by forming an anode near a two-dimensional electron-gas forming interface in a light absorption layer and shaping a cathode in the position deeper than the anode in the light absorption layer in a semiconductor photoconductive photodetector having a modulation doping structure. CONSTITUTION:An electrode forming section is removed as deep as approximately 2000Angstrom  in an InGaAs layer in a cathode 8 while an anode 7 is formed onto an n<+>-InAlAs layer 5, and the cathode 8 is shaped, and alloyed, thus forming an alloy layer 9 in the anode 7 up to a two-dimensinal electron gas 6 and an alloy layer 10 in the cathode 8 up to a section in the vicinity of approximately the center of the InGaAs layer 3. Consequently, electrons generated in the InGaAs layer 3 by optical pumping shape the two-dimensional electron gas 6 by the bending of a band, and are extracted to the anode 7 by a strong electric field. Holes generated near the surface shift to deep positions in the layer thickness direction by the bending of the band, but they move to the positions of the strong electric field because the cathode 8 is shaped up to approximately 2000Angstrom  in depth in the InGaAs layer.

Title: Dc motor using reed switch
Inventor: EGUCHI SHINTARO
IPC: H02K29/08
Filed: 1994-04-07
Abstract: PURPOSE:To save additional semiconductor circuits substantially by a method wherein the switching operation of mechanical contacts in accordance with the ON/OFF of a reed switch is utilized for the detection of the pole of a rotor. CONSTITUTION:When the pole N1 of a rotor reaches a position above a reed switch L, the reed switch L is turned on, the circuit of an electromagnet M is closed, the electromagnet M is excited and attracts the pole N1 and a rotating force is produced. Then, when the pole N1 reaches a position above the electromagnet M, the reed switch L is turned off, the circuit of the electromagnet M is opened and an electromagnetic force is lost. However, the rotor is further turned half around by an inertia. Thus the poles N1 and N2 are alternately attracted by the electromagnet M and the rotating force is produced to continue the rotation of the rotor. By using the reed switch L, the position of the rotor can be detected easily and an economical rotation mechanism can be obtained.
