Title: Nonlinear element
Inventor: SAITO TAKESHI
IPC: H01L29/861
Filed: 1984-10-12
Abstract: PURPOSE:To improve the normal and reverse symmetricalness of voltage-current characteristics by a method wherein two diodes made of insulating films and amorphous silicon films successively laminated with the same metallic films formed into the same type are connected in series in the reverse direction. CONSTITUTION:Silicon nitride or silicon dioxide insulating films 23, i-type amor phous silicon films 24 and N type amorphous films 25 are successively laminated on two lower electrodes 21, 22 formed of metal at the adjoining position on a glass substrate 20. Next the insulating films 23 and the i type amorphous silicon films 24 are formed into island type parts by etching process to be left only on the lower electrodes 21, 22. Besides, silicon nitride or silicon dioxide insulating films are formed into passivation films and then a contact hole for leading out electrodes is opened. Finally two MIS diodes may be connected with each other by upper electrodes 27 through the intermediary of the contact hole. Through these procedures, the threshold value may be increased to improve the normal and reverse symmetricalness of voltage-current characteristics.

Title: Paper sheet housing device
Inventor: SUGIYAMA HIDEAKI
IPC: B65H3/54
Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To smoothly store or deliver a paper sheet regardless of the number of the paper sheets by applying elastic force from side guide members to a paper sheet loading member under the condition of loading many paper sheets to stably support the paper sheets, and releasing the elastic force when the paper sheets are reduced and the paper sheet supporting member is elevated. SOLUTION: The guide parts 15b of a pair of side guide plates 15 arranged on both sides of a recording paper supporting plate 12 are deformed toward the recording paper P setting the lower ends as fulcrums, and the upper ends are brought in contact with the upper layer part of the recording paper P loaded on the recording paper supporting plate 12. Accordingly, the recording paper P is sandwiched from left and right both sides, and it is uniformly arranged along the delivery direction A. With the delivery of the recording paper in order, the recording paper supporting plate 12 is in order pushed up by coil springs 13. Thereafter, when the recording paper P is remarkably reduced, the upper end parts of the guide parts 15b are brought in contact with both side edge parts of the recording paper supporting plate 12.  As a result of this, displacement of the guide parts 15b toward the recording paper P is regulated, and the recording paper P is not deformed.

Title: Battery recharge detecting circuit
Inventor: YAMASHITA HARUKI
IPC: H02J7/10
Filed: 1988-08-29
Abstract: PURPOSE:To recharge a battery corresponding to its capacity by constituting a battery charge detecting circuit with a circuit for detecting the peak charge voltage, a circuit for holding the peak voltage for a predetermined interval, a comparator for detecting - V and a latch circuit being triggered by the output from the comparator. CONSTITUTION:An operational amplifier 2 employs a voltage follower configuration and charges a holding capacitor 8 through a reverse-current preventive diode 3 and a resistor 6 such that it will have a voltage identical to the voltage across a resistor R2. A voltage higher than the voltage at the operational amplifier 2 by such amount as corresponding to the voltage drop of a resistor R3 is fed to the inverted input of a comparator 4. When the battery charge voltage passes through the peak and drops to - V, the output of the comparator 4 inverts to high level so as to hold Q output of next latch at high level. At the same time, a discharge transistor 7 is turned ON to discharge the capacitor 8.

CONSTITUTION:Recessed sections 17-19 are formed in the side walls 13-16 of a case 12 and ceramic terminals 20-22 are respectively mounted in the sections 17-19. The width La' of the end section 22a of the terminal 22 facing the external part of the case 12 is made different from the width Lb' of the end section 22b of the terminal 22 facing the internal part of the case 12 and, when virtual lines 25 and 26 are extended along the side faces of the terminal 22, the lines 25 and 26 intersect each other at an angle theta at a virtual point 27. The planar shape of the terminal 22 becomes a tapered shape at the angle theta and, when only the relative horizontal position between of the terminal 22 against the recessed section 19 is adjusted, the clearance between the terminal 22 and section 19 can be freely adjusted. Therefore, the positional accuracy of the ceramic terminals in the width direction can be improved.

Title: Automatic hose winding device
Inventor: MIYASHITA SUSUMU
IPC: B65H75/40
Filed: 1986-09-13
Abstract: PURPOSE:To reliably control unwinding and winding of a hose, by a method wherein swing of the support arm of a roller for bending and energizing a hose is transmitted to a drum brake member through a Bowden cable to control a winding drum. CONSTITUTION:A hose 26 wound around a winding drum 4 can be bent by means of an unwinding roller 21 and an energizing roller 24 to unwind it. During unwinding of the hose 26, a support arm 24 of the energizing roller 22 is rotated against a spring 27 by means of tension, a Bowden cable 29, pivotally supported to the support arm, is lifted up to rotate a seesaw lever 31, and a brake member 34 at its tip part is separated from a clutch roller 12. Thus, the winding roller 4 is brought into a rotatable state, and is unwound in linkage with unwinding of the hose 26. But, since, during the stop of unwinding, a tensile force is decreased to return a support arm 22 and the brake member 34 is brought into contact with the clutch roller 12, the winding roller 4 is locked. During winding, clutch rollers 10 and 12 are brought into contact with each other through control of an accel 8 for winding.

When the number of revolution 13 of the engine is less than the number of revolution 10 in case of maximum load, command speed 9 is corrected by a second comparator 18 in response to the output. The command speed 9 is compared with car speed 14 converted into voltage by second F/V conversion 20 by a third comparator 19, and a slip clutch 5 is controlled lest difference should be formed. When the number of revolution 13 of the engine drops up to the number of revolution 11 or less where snow removing is unsuitable, the command speed  9 gives a command bringing equivalently zero to the third comparator 19, and load is reduced automatically.
