Title: Combustion chamber of direct injection type diesel engine
Inventor: DOBASHI KEIICHI
IPC: F02B3/06
Filed: 1990-09-06
Abstract: PURPOSE:To suppress increase of a volume of a reentrant type combustion chamber due to the presence of recessions to a minimum by setting lower ends of the recessions formed on a peripheral wall of the combustion chamber upper than a lower end of the peripheral wall. CONSTITUTION:Reentrant type combustion chamber 12 is formed on an upper part of a piston 10, while a plurality of recessions 18 are formed on a peripheral wall of the combustion chamber 12 in a circumferencial direction. Lower ends of the recessions 18 are set upper than lower end of the peripheral wall 16. The recessions 18 do not reach the lower end of the peripheral wall, so that a vertical length is reduced. It is thus possible to suppress the increase of a volume of the reentrant type combustion chamber 12 due to the presence of the recessions 18.

Title: Amplifier device
Inventor: MIKAMURA YASUKI
IPC: H03F1/32
Filed: 1989-09-11
Abstract: PURPOSE:To weaken the saturation of an amplifier and to obtain an output signal with less distortion even when a large input optical current comes by shifting a level of an output signal of a transimpedance type amplifier till a gate circuit can be controlled to be switched in response to the fact that an input signal of the transimpedance amplifier is larger or smaller than a prescribed value. CONSTITUTION:A level shift/buffer circuit 101 shifts the level of a signal given to a gate of a FETQ5 so as to make the FETQ5 conductive/nonconductive corresponding to the fact that an input signal of a transimpedance amplifier 2 is increased or decreased with reference to a prescribed value. That is, when an input optical current iPD coming to the amplifier 2 is increased, the output voltage Vout is decreased accordingly. The output voltage Vout is shifted up to a prescribed level by the circuit 101 and also up to an input level of the inversion circuit 102. Then the signal inverted by the inversion circuit 102 is increased as the input optical current iPD increases. Thus, the FETQ5 is conductive when the average value of the light power made incident on the photodiode 1 exceeds a prescribed value by selecting properly a threshold voltage of the FETQ5 to a value and a shunt branching part of the input optical current iPD is formed.

Title: Axial flow air blower impeller
Inventor: IZUMI YOSHIKI
IPC: F24F1/00
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To enhance a silent sound characteristic by arranging a groove penetrating through both surfaces of a blade in a part except an outer peripheral edge part of the blade of an impeller, making a width of the groove on the pressure surface side of the blade larger than a width on the negative pressure surface side in a cross sectional shape of this groove, and reducing an Nz sound level while promoting noise reduction by reduction in separation and turbulence. SOLUTION: A groove (a slit) 7 obliquely penetrating through the pressure surface side and the negative pressure surface side of a blade 2 is arranged in a range of a part except an outer peripheral edge part of the blade 2 of an impeller 1, and in a cross sectional shape of its groove 7, a width (t2 ) on the pressure surface side of the blade 2 is made larger than a width (t1 ) on the negative pressure surface side. Therefore, when the impeller 1 rotates and performs an air blowing action, separation and turbulence on the rear edge of the negative pressure surface side of the blade 2 can be restrained by sufficiently guiding the flow from the wide groove 7 on a pressure surface of the blade 2, and as a result, noise reduction is promoted.  Since the flow on which separation and turbulence from the front blade 2 enters all the way into the rear blade 2, a level of an Nz sound (a rotation sound of a moving blade) is reduced, and a silent sound characteristic is improved.

Title: Magnetic recording system
Inventor: SUZUKI JIRO
IPC: G11B5/02
Filed: 1984-11-09
Abstract: PURPOSE:To prevent forgery by recording normal data on a high resistance magnetic force layer and a dummy signal on a low resistance magnetic force layer. CONSTITUTION:A magnetic card base 1 has the high resistance magnetic force layer 2, a highly transmissive layer 3, the low resistance magnetic force layer 4, a protection layer and a printed layer 5. Magnetic paints I, II and III are sequentially applied to a titanium oxide kneaded polyester film, for instance, to be laminated, thereby setting it as a magnetic card. All '1' and all '0' are recorded on the obtained magnetic card by a magnetic head. A signal recorded on the high resistance magnetic force layer is magnetically sealed by the highly transmissive magnetic force layer, because its output is decreased below the slice level of a reader. The signal is degaussed by the 2nd head, and can be read by the 3rd head. However, in order to read it, a specific DC sub-magnetic field is necessary.

Filed: 1996-08-20
Abstract: PROBLEM TO BE SOLVED: To ensure a large space at the internal part of a coupling by providing at least three lap parts formed by bending and lapped with each other in a radial direction. SOLUTION: A coupling 10 is formed of a flexible material being bendable, and at least three lap parts 14, 16, and 18 lapped with each other around the same axis L are provided. When, for example, one release end part 22 of the coupling 10 is pulled in an axial direction, the position of an annular fold line being a boundary between a third lap part 18 and a second lap part 16 between first and third lap parts 14 and 18 is consecutively changed in the axial direction of the coupling 10. As a result, the lapping length W of the lap parts 14-18 is gradually decreased, and the length of the coupling 10 is increased along with the decrease of the lap length. Thus, setting the axial length W of the lap parts 14 and 18, the stretchable length in an axial direction of the coupling 10 is increasable.
