Abstract: A wheel for maintaining a constant distance between an ink discharge plane of a recording head and a recording sheet is provided on a carriage such that it is upstream of the recording head as viewed in the direction of movement of the recording head in a unidirectional print mode. A sensor monitors whether the recording sheet is moved off a contact of a feed roller which feeds the recording sheet to a record position and a pinch roller. Before a trailing edge of the recording sheet is moved off the contact of the feed roller and the pinch roller, bilateral recording is conducted to print in each of forward movement and backward movement of the carriage. When the sensor detects that the trailing edge of the recording sheet has been moved off the contact of the feed roller and the pinch roller, the recording is switched to unilateral printing. The print range at the trailing edge of the recording medium is thus extended.

Abstract: In an image processing apparatus, in order to integrate a recording device for obtaining a hard copy and an image reading device for reading a desired image, the image reading device is disposed above the recording device, and the apparatus has a housing for housing a first control circuit unit for the recording unit and a second control circuit unit for the image reading device, a storage unit for temporarily storing an image processed between the apparatus and the host computer side and an image to be output to the recording device, and a power supply unit, so as to minimize the area required for the apparatus. The apparatus takes a countermeasure against noise. The apparatus can be connected to the host computer via only one Bicentronics-standard interface cable, and can obtain hard copies of different sizes.

Abstract: A facsimile apparatus comprises a facsimile unit for sending data corresponding to image data that has been received, and a printer unit for performing image recording by discharging ink droplets in accordance with data sent from the facsimile unit. A first CPU for the control of the facsimile unit sends, after one page of image data, data in a predetermined pattern and further a paper exhausting command to the printer. A second CPU of the printer unit performs a paper exhausting operation upon receiving the paper exhausting command, after recording of the predetermined pattern, and upon conveying the recording paper up to a predetermined position, sends a signal for starting detection of the predetermined pattern to the first CPU. The first CPU thereby receives a detection signal from a photo sensor. The second CPU further conveys the recording paper, and at a timing of exhausting out of the apparatus, sends a signal for the detection end of the predetermined pattern to the first CPU.

Abstract: A liquid level detecting mechanism for detecting the liquid level in a vessel for storage of liquid, includes a light emitting unit and a light receiving unit disposed opposite to the vessel for storage of liquid or a chamber communicating with the vessel. The light receiving unit detects the liquid level in the vessel in accordance with the quantity of received light from the light emitted from the light emitting unit, and members in contact with liquid which are arranged between the light emitting unit and the light receiving unit, the members being formed of a material having high wettability relative to the liquid.

Abstract: If one page of recording is terminated, a carriage moves to a position at which a recording head is located opposite a cap. Then, the ink is discharged through nozzles of the recording head onto temperature detecting element within the cap. Temperature change of the temperature detecting element upon contact with the ink is output from a detecting circuit, and the normal discharge of ink is detected by discharge detecting means. In this way, a decrease in the ink remaining or the detection of ink nondischarge can be securely made.

Abstract: A double-shot molded resin article comprises a primary molding part and a secondary molding part. The secondary molding part is molded from a thermoplastic resin having a melting point higher than the melting point of the primary molding thermoplastic resin. The primary molding part has a plurality of raised portions formed upon its surface so as to be fusion bonded to the secondary molding part. These raised portions are fused by means of the secondary molten resin at the time of the secondary molding process, whereby the primary and secondary molding parts are fusion-bonded to each other.

Abstract: A buckle includes a first buckle body and a second buckle body. The first buckle body is inserted into the second buckle body so s to be made incapable of withdrawl from the second buckle body and is released from engagement with and made capable of withdrawl from the second buckle body by inserting it further into the second buckle body from its engaged state. The second buckle body is integrally provided with flexing portions which are formed so as to face the free end of the first buckle body when the same is engaged with the second buckle body.

Abstract: A phenolic polymerization inhibitor is recovered from a styrene distillation residue containing the phenolic polymerization inhibitor by a method which comprises extracting the inhibitor from the styrene distillation residue with an oxygen-containing organic solvent having not more than 6 carbon atoms, adding an aromatic hydrocarbon solvent to the oxygen-containing organic solvent phase consequently obtained, and subjecting the resultant mixture to distillation thereby separating the mixture into a solution of the phenolic polymerization inhibitor in the aromatic hydrocarbon solvent and the oxygen-containing organic solvent. The recovered solution is put to use as a polymerization inhibitor either in the unmodified form or in a form separated from the aromatic hydrocarbon solvent.

Abstract: A compact buckle, streamlined in appearance, comprises a main body and a stopper piece. The main body includes a pair of side frames, and three shafts disposed between the side frames in such a manner as to extend from one side frame to the other. The stopper piece is axially and pivotably supported between the side frames. The stopper piece is provided with a retaining projection which has a sloped surface for cooperating with a correspondingly sloped surface of a winding shaft, which is one of the aforenoted three shafts, in order to frictionally engage and entrap a belt portion therebetween thereby securing the belt portion within the buckle.

Abstract: A very safe buckle, formed of plastic, is provided which enables a strap to be inserted and clamped easily and quickly, and which prevents the strap from being inadvertently loosened or pulled free of the buckle no matter how the strap or the buckle is pulled about. The buckle is comprised of two adjacent bars spanning the space between the sides of the buckle. The strap is passed between the two bars. One of the bars is rotatable and has a polygonal cross-section, the arrangement being such that the rotation of the rotatable bar reduces the size of the gap between the rotatable bar and the other bar, which is fixed, thereby clamping the strap securely between the bars.
