Title: Call current supplying circuit
Inventor: UEKI ISAMU
IPC: H04M19/00
Filed: 1983-03-04
Abstract: PURPOSE:To supply stably a call current even in case of an area in which a call current is small, and to make a device small-sized by a conversion to an IC, by turning on and off a feedback loop for comparing a constant-current and a detecting current, by a control signal. CONSTITUTION:A pair of detecting circuits 16, 17 convert each voltage between connecting terminals 12, 13 to a subscriber's circuit and a DC power source 22 to a current by resistances 23, 24 and current mirror circuits 25, 26 and the converted current is supplied to an adding circuit 18, further an output current of the adding circuit 18 and a current of a constant-current source 19 are supplied to a feedback circuit 20 having a feedback loop, and this feedback loop is turned on and off by a control signal from a controlling circuit 29. When the feedback loop is turned off, a constant resistance feed by which a feed resistance of DC feeding circuits 14, 15 becomes constant is obtained, and in case the feedback loop is turned on, in an area in which a call current is small, a constant voltage feed by which voltage between the terminals 12, 13 becomes constant is obtained.

Title: Automatic correction system for recognized character
Inventor: NAKAMURA OSAMU
IPC: G06K9/03
Filed: 1990-02-16
Abstract: PURPOSE:To save the labor for confirming and correcting operation by correcting the recognized character automatically for plural character positions where similar misrecognition is caused by correcting the character only once. CONSTITUTION:This system is equipped with a table 4 which holds all character recognition results and a rearrangement decision means 5 which decides whether or not similar misrecognition is caused as to other character positions when misrecognition wherein a correct character candidate is obtained as a 2nd or succeeding candidate is corrected to obtain the candidate as a 1st character candidate. Namely, the rearrangement decision means 5 rearranges character positions where it is judged that similar misrecognition is caused so as to set the character candidate which is estimated as the correct character candidate as the 1st candidate. Consequently, the similar recognition results are corrected only once to correct recognized characters at plural character positions where the similar misrecognition is caused automatically, thereby saving the labor for the confirming and correcting operation.

CONSTITUTION:A P<+> type source region and a P<+> type drain region 21 are formed by diffusion in the prescribed region of the N type semiconductor substrate 20, and the shallowly extended P<+> type region 23 is formed at the position corresponding to the lower part of the gate electrode 22 to be mentioned later making one edge to come in contact with the former. Then the whole surface is covered with an insulating layer 24, and the gate electrode 22 is formed on the layer 24 as to be protruded on the upper part of the region 23. As the method to form the region 23 in the channel region at the lower part of the electrode 22, it is enough to implant impurity ions at the angle of inclination alpha of about 45 deg. from the face 25 crossing the surface of the layer 24 at right angles toward the direction of the layer 24. Accordingly even when transference of impurity ions in the layer 24 is activated according to invasion of water, etc., and the N<-> type region intends to generate in the channel, it is intercepted by the region 23, and the offset phenomenon is not generated.

Title: Cut sheet feeder
Inventor: MIZUGUCHI TAKUYA
IPC: G03G15/00
Filed: 1990-02-16
Abstract: PURPOSE:To restrain each cut sheet from being curved as well as to concurrently move the bow of each cut sheet to the direction of feeding by providing fan type rollers which push each cut sheet, coaxially with fan type auxiliary rollers each of which makes contact with each cut sheet later than the fan type rollers, and is identical in radius to each fan type roller but is shorter in a length of an arc than each fan type roller. CONSTITUTION:An uppermost cut sheet 1 is fed out by means of the rotation of fan type rollers 6, but is curved because the both tip corner ends of the cut sheet 1 is pressed by separating pawls 3 and 4. In this case, fan type auxiliary rollers 7, each of which is identical in radius to each fan type roller 6 but is shorter in a length of an arc than each fan type roller, are mounted on a roller shaft 5 wherein each end section at the side opposite to the direction of the rotation of the roller shaft 5 is trued up in such a way that each auxiliary roller makes contact with each cut sheet 1 later than each roller 6 when the roller shaft 5 is rotated. This thereby restrains each cut sheet 1 from being curved by the auxiliary rollers 7, thereby pushing the bow of each cut sheet out to the left concurrently by means of rotation.

Title: Control device for ignition timing of internal combustion engine
Inventor: NAKANIWA SHINPEI
IPC: F02P5/15
Filed: 1987-02-21
Abstract: PURPOSE:To obtain an ignition timing control device for restraining the fluctuation of an engine speed and the vibration of a vehicle by correcting the basic ignition timing toward restraint of the change in the engine speed based on the changing rate of an engine speed per unit time when the driving is detected in state of acceleration and deceleration. CONSTITUTION:A control device 6 is employed to obtain any changing rate of engine speed per unit time by imputting signals from a crank angle sensor 12. Following this, a throttle valve opening from a throttle sensor 5 is inputted so as to calculate the changing rate thereof, and it is judged whether any acceleration driving is present or not depending upon the magnitude of the charging rate value. When the judgement on acceleration is made right after second judgement (e.g.within one second) from the first, a corrective lead value is retrieved based upon the changing rate of engine speed per unit time. The value is set in such a way as to retard the ignition timing in a range wherein the engine speed is liable to increase. And, the ignition timing is so calculated as to output an ignition signal by adding a corrective lead value to the basic ignition timing set separately, thereby restraining the fluctuation of an engine speed and the vibration of a vehicle.
