Abstract: PURPOSE:To enable the correction of characters in the preceding line, positioning between a paper and a printing section and other operations at low cost by facilitating the control of the angle of rotation of a platen with a DC motor while the rotation of the platen can be done forward and reversely. CONSTITUTION:At the time t1, an electromagnet 22 is electrically energized and attracts an engaging member 20 against an elastic force of an elastic member 20B to release the engagement between an engaging section 20A and a convex section 19A of a cam member 19 while a DC motor 11 is electrically energized and turns the cam member 19 to rotate a platen 2 through a drive gear 5, an intermediate gear 6 and a driven gear 3. Then, the energization of the electromagnet 22 is turned OFF and the engaging section 20A slides with the elastic member 20B in the perimeter of the cam member 19 turned by a moderate force. Thereafter, after the engaging section 19A of the engaging member 20 is engaged with the convex section 19A, the DC motor 11 stops to halt the platen 2 at a specified angle of rotation. If the platen 2 is to be turned reversely, the DC motor 11 may be only energized with current of the opposite polarity.

Title: Input circuit
Inventor: SAITOU SHINJI
IPC: H03K19/013
Filed: 1980-07-07
Abstract: PURPOSE:To increase the switching speed, by providing a generating means of a given potential between the emitter of the 2nd transistor (TR) of npn type in which a load element is inserted between the 1st TR of pnp type and the power supply voltage application point and the base is connected to the emitter of the 1st TR, and the reference potential point. CONSTITUTION:Since the emitter of a PNP TR21 is connected to a positive polarity power supply via a load resistor 21, it is conductive at all times. When an input signal In is at a low potential VIL, the collector potential of the TR21 is at VIL+VBE. On the other hand, when the input signal is at high potential VIH, the collector potential of the TR21 is at V1H+VBE. Since the NPN TR21 is not conductive if the base potential is not more than VB+VBE, where VB is the output voltage of the constant power supply voltage 23, the switching control of the TR12 can be made, by setting the VB from V1L to V1H.

Title: Radio auction system
Inventor: KANAZAWA YASUSHI
IPC: G06Q50/34
Filed: 1990-04-07
Abstract: PURPOSE:To simplify the constitution of an input circuit and to decrease the number of parts by using the switch signals of an bidding device as the bidding data and adopting the address addition data communication to make an interface device select and input successively the bidding data on each bidder to a data processing part. CONSTITUTION:Each bidder transmits the bidding data via his own radio bidding device 1, and these transmitted data are received by a receiver of the auction seller side. This data communication is carried out with addition of addresses, and an interface device 3 selects the data corresponding to a data request command signal out of those transmitted addressing bidding data and inputs them to a data processing part 4 in the order of commands. These operations are repeated and therefore the overall bidding situation is grasped. That is, many received bidding data are sequentially transferred to the part 4 for each address via the device 3 and not transferred en bloc. Thus the transfer circuit can be used in common to the bidders. As a result, the circuit constitution is simplified and the number of parts is decreased.

Title: Frequency synthesizer
Inventor: TAKEUCHI ISAO
IPC: H03L7/087
Filed: 1994-04-28
Abstract: PURPOSE:To provide an output of a frequency signal other than an integral number of multiple of a reference signal frequency by changing a frequency division ratio of each frequency divider to be 1/N or 1/(N+61) periodically and in a different timing under the control of a control means. CONSTITUTION:Since the frequency division ratio of frequency dividers 14, 15 is changed periodically in different timing, a phase error between each frequency divided signal and a reference frequency signal fr fluctuates periodically. However, an average phase error of them is identical to each other by adding phase error signals by an adder 13 and then a VCO 5 is controlled in a uniform state. As a result, a control section 16 implements oscillation control with a frequency division ratio in combination of frequency division ratios 1/N and 1/(N+1) stably. For example, the frequency divider 14 of the frequency dividers 14, 15 selects a frequency division ratio of 1/N or 1/(N+1) alternately and the other frequency divider 15 selects a frequency division ratio of 1/(N+1) or 1/N alternately. Thus, a frequency signal fc whose frequency is a multiple of an integral number +0.5 with respect to a frequency of the reference frequency signal fr is generated.

IPC: G01V8/14
Filed: 1990-04-06
Abstract: PURPOSE:To freely specify a sensing region by a method wherein a sensor body is freely rotatable on a plane approximately parallel to a fixing face with respect to a body and a rotating axis protruding from a side of a mirror block is pivoted so that a rotation center of the body and the rotating axis are perpendicular to each other while the rotating axis is freely rotatable with respect to a housing of the mirror block body. CONSTITUTION:A sensor 2 is coupled to a body 3 fixed on a ceiling-like fixing face via a base 4. That is, a protruding rib 5 is made protrude on a required part on an inner periphery of a lower opening of the body 3 while a flange 6 having a cut 7 corresponding to the protruding rib 5 is made protrude on an outer periphery of the sensor 2. The cut 7 is thus aligned with the protruding rib 5 and the sensor 2 is fitted into the lower opening of the body 3 while the flange 6 is positioned above the protruding rib 5. A fixing spring 8 is a C-shaped anti-escape spring in elastic contact with the inner periphery of the lower opening of the body 3 whereby the sensor 2 is freely rotatable with respect to the body 3. Thus adjustment of a sensing region is possible with a simple structure.
