Title: Orthogonal folding device
Inventor: HIROSE HITOSHI
IPC: B65H45/18
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To make a chopper arm of an orthogonal folding device lighter than that of an aluminum alloyed one in weight and higher rigidity by constituting it with a carbon fiber reinforced plastic, in a folding machine in a rotary press. SOLUTION: A chopper arm 21 consists of a carbon fiber reinforced plastic as its material, whereas that of the device heretofore in use is composed of an aluminum alloy as the material. Consequently, an extent of flexure is made to be very little even in a folding point or position where the chopper arm 21 goes down maximally, and further the extent of variable torque due to load of the chopper arm 21 itself is also made to be lessened, making it so as not to impose any unnecessary load on the folding machine.  Moreover, since rigidity is high as far as approximately thirty times over as compared with that made of aluminum alloy, the extent of flexure of the chopper arm in time of folding work can be minimized, through which any paper break and cut in time of the folding work will in no case occur at all, and thus such one that gives no adverse effect to the accuracy of folding finish is securable.

Title: Code reproducing circuit with automatic threshold value control function
Inventor: SUEHIRO YOSHIKAZU
IPC: H03K5/08
Filed: 1984-03-27
Abstract: PURPOSE:To increase a dynamic range in order to attain an AC connection for a code reproducing circuit containing an automatic threshold value control function which is used to an optical data ring, etc., by reducing the variance of pulse width with a comparator having the constitution of a Schmitt circuit. CONSTITUTION:Inputs shown by waveforms 51-53 are applied to an input terminal 32, an adverse phase input terminal 33 and a forward phase input terminal 34 of a comparator 31 respectively. The output of a waveform 54 is delivered from an output terminal 35. The waveform 53 of the terminal 34 changes its level instantly by a feedback resistance 43 in the rise and fall modes of the adverse phase input waveform 52. Then the reproduction of a code is possible although the waveform 52 is converted to a bias potential after a long period of time. Thus an AC connection is possible. Furthermore the effect of the dull input waveform 51, if caused, is applied equally between rise and fall modes since the waveform 52 has symmetrical oscillation to a bias potential. Thus the pulse width has no change.

Title: Elastic crawler belt
Inventor: SAKAI KENICHI
IPC: B62D55/253
Filed: 1988-03-10
Abstract: PURPOSE:To obtain a stiff elastic crawler belt having high rug rigidity and with a high mud removing property and good durability by making the depth of a groove between two rugs smaller than the depth of a rug-to-rug space between core metals, making the rot of a rug nearly parallel to the core metal, and making the width of the rug root larger than the width of the core metal and the width of the rug-to-rug space. CONSTITUTION:The depth (d) of a groove 11 between two rugs 7, 8 is made smaller than the depth D of a rug-to-rug space 9 which is formed between core metals 3, and the root of the two rugs 7, 8 is made nearly parallel to the core metal 3 while making the width B of the lug root larger than the width (b) of the core metal and the width S of the rug-to-rug space. As a result, since the depth (d) of the groove between rugs 7, 8 is small, the attachment of rubber onto the core metal 3 can be sufficiently ensured, while the rigidity of the rugs can be ensured even if rug tops t1, t2 are made narrower, improving biting and a mud removing property, preventing the generation of water film between a road surface and the rugs 7, 8, and increasing friction coefficient. Also, since the circumferential-direction width t2 on the top of the rug 8 on the rear side in the advancing direction is made smaller than the width t1 of the front side rug 7, elasticity can be increased while improving vibration resistance and a mud removing property.

Title: Exhaust emission control device for engine
Inventor: TAKAMI AKIHIDE
IPC: F02D41/34
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To improve overall NOx eliminating performance during engine operation with respect to an exhaust emission control device, in which an engine exhaust passage is provided by disposing a lean NOx catalyst that absorbs NOx and sulfur component in an oxygen excess atmosphere thus oxygen concentration in exhaust emission is high, while emitting NOx when oxygen concentration decreases for purification through reduction. SOLUTION: An exhaust passage, that is disposed in the upper stream of a lean NOx catalyst with a three-way catalyst in which HC purification rate, is significantly higher than CO purification rate, when oxygen concentration is low. Fuel injection is feedback-controlled so that the air-fuel ratio of a combustion chamber approaches approximately the ideal air-fuel ratio when the amount of NOx absorbed by the lean NOx catalyst is increased (SB1, 2). At the same time, fuel injection is divided into two parts for intake stroke and compression stroke (SB3 to 9), so that the concentration of CO in exhaust emission is increased.

IPC: G03G15/01
Filed: 1984-03-28
Abstract: PURPOSE:To render the whole body of a color copying device small in size and to enhance transfer efficiency by using external voltage and an endless photosensitive drum small in diameter. CONSTITUTION:A transfer drum 6 is arranged below the photosensitive drum 1 in contact with it, and since the drum 1 is used for forming an electrostatic latent image, its diameter can be reduced in diameter to <=1/2 of the transfer drum 6, so long as it is endless. Further, in order to enhance transfer efficiency, the surface 1'' of a photosensitive layer having an electrostatic latent image is brought into close contact with the dielectric layer 7'' of a transfer paper 7 and the transfer of the photosensitive latent image formed on the surface 1'' is executed not only by an electric field formed by itself, but also by a supplemented external electric field. Since it is not advantageous from the view point of leakage and not good effect on the development to ground the conductive substrate 1' of the drum 1 and to elevate voltage of the drum 6 as well as the paper base of the electrostatic recording paper 7, it is preferable to ground the drum 6 and insulate the conductive substrate 1' of the drum 1 from the ground, and to apply DC current or to ground it through a Zener diode.

IPC: G11B19/28
Filed: 1987-03-13
Abstract: PURPOSE:To eliminate a pilot signal for controlling a time base by maintaining the rotation of a recording disk at a degree that a synchronizing signal can be detected, even if the synchronizing signal comes not to be detected, and starting immediately controlling the time base by the synchronizing signal when abnormality is disappeared. CONSTITUTION:When an HD signal comes not to be detected because of a drop-out or the like, during a reproducing operation, a PLL servo loop goes to OPEN and simultaneously an F servo loop goes to OFF. Then, similarly to the time of a start, the rotational speed of the disk 1 is set at a value within the range of + or -5% of the prescribed rotational speed so that the detection of the HD signal can be performed again. Thus, the run away of a spindle motor 33 or the like is prevented, and simultaneously, the PLL servo can be drawn in a short time, when the phenomenon of the drop-out is disappeared and the synchronizing signal comes to be detected again. Besides, the time base can be favorably controlled without using the pilot signal.
