Filed: 1978-06-13
Abstract: PURPOSE: To provide a simple and economical arrangement for anti-frosting and anti-freezing apparatus of revolving window, in which electromotive force induced  in rotor of a revolving window driving motor is impressed to heating wire embedded in the revolving window so as to heat the same, whereby it is enabled to prevent frosting and freezing of the revolving window.  
     CONSTITUTION: When switch 11 is turned ON to connect power source 4, rotor 7 starts rotation and at the same time electromotive force induced in rotor winding 8 in rotor 7 is impressed to heating wire 9 which is embedded in revolving window 2, so that window 2 is heated and its frosting and freezing can be prevented. In the above arrangement, rotor winding 8 in the same structure as stator winding 6 is employed in rotor 7, so that secondary electromotive force induced in rotor 7 can be used for other purposes than the driving force for rotating shaft 10.

Filed: 1981-05-14
Abstract: PURPOSE:To bend a work zigzag with ascended bending devices and to improve the precision of formed goods, by allowing a pair of bending devices having opposite bending directions to move, ascend, and descend just under the work. CONSTITUTION:When a work W is fed and is stopped, a clamping die 15 and a pressing die 17 are moved toward a bending die 14 by a cylinder 18, and the work W is interposed between these dies and the bending die 14. The bending dies 14 and a rotary base 13 where the clamping die 15 is put are operated by a torque actuator 12 to bend the work W along the bending die 14. After the bending work, the clamping die 15 and the descending 17 are separated from the work W, and this bending device E descends by a device D for ascending and descending, and the rotary base 13 is returned to the original position  by the torque actuator 12. Simultaneously, a moving device C is operated to lead the other bending device E to an aperture 4 of a work stage B. When the work  is fed by a prescribed length, the device D for ascending and descending is  operated, and the bending device rises to bend the work W in the opposite direction by the similar operation, and thus, the work is bent zigzag.

Filed: 1987-03-27
Abstract: PURPOSE:To prevent a spark and a progress to a damage and to improve the reliability of a piezoelectric bimorph by composing part of the surface electrode of the bimorph of a conductive substance having flexibility to crack the surface electrode or to separate the electrode. CONSTITUTION:Piezoelectric elements 2, 2' of PZT or the like are bonded through an intermediate electrode 1 made of carbon fiber or the like. Surface electrode first layers 3a, 3a' made of silver are baked on the reverse surface to the electrode 1 of the elements 2, 2'. Epoxy conductive materials (adhesives) 3b, 3b' which, for example, contain silver powder are bonded as surface electrode second layer 50-100mum thick on the layer 3a, 3a' to form a surface electrode 3. Leads 5 are soldered to the layers 3a, 3a', and leads 5' are soldered to an intermediate electrode 1, and extended to terminals 6, 6'. Since the layer 3b has flexibility and shrinkability, no crack occurs. Since the layer 3b is not cracked, even if the piezoelectric elements themselves are cracked, it is elongated or shrunk by a driving voltage to displace as designated by solid and broken lines.

Title: Terminal communication control system
Inventor: MUTA KIYONARI
IPC: G06F13/00
Filed: 1980-05-29
Abstract: PURPOSE:To reduce the waiting time for polling, by giving a dynamic change to the sequence of polling by a request from the program side. CONSTITUTION:When a polling priority service is requested to a certain terminal from the program of a terminal control device, the polling to the terminal is inserted into a certain space under an ordinary cyclic polling to increase the polling frequency of the terminal. When a data output is requested to a certain terminal from the program of the terminal control device, this request is registered to a priority service flag register 4. Thus the cyclic polling is once discontinued to start an output sequence to the terminal. In such a way, the polling sequence can be changed in a dynamic way by a request from the program side.

Title: Push-up device for sewing machine
Inventor: MIZUNO YASUSHI
IPC: D05B29/02
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To provide a push-up device for sewing machine by which the movement of presser bar upward to a prescribed position can be satisfactorily detected even when the position of fixing that presser to a presser bar is adjusted. SOLUTION: When a presser foot 11 is moved up proximately to the upper dead point, one end 87a of lever 87 is abutted to the upper end part of that presser foot 11 and afterwards, the lever 87 is swung clockwisely corresponding to the increase of presser foot 11. When the lever 87 is swung proximately to the position shown by a real line in the figure, a sensor part 81 detects the proximity of other end 87b. Since one end 87a is directly abutted to the presser foot 11, the state of swinging the lever 87 is satisfactorily reflected with the real position of presser foot 11. Therefore, even when the fixing position of presser foot 11 is adjusted, it can be satisfactorily detected the presser foot 11 is moved up proximately to the upper dead point.  Further, since the lever 87 and the presser 11 are separated when the presser foot 11 falls down, the fixing position adjustment work or the like of presser foot 11 can be easily performed.

Filed: 1989-03-27
Abstract: PURPOSE:To enable elimination of an artificial observation error by providing means for detecting leading and trailing edges, delaying a pulse of the former detection, and comparing positions of a pulse of the latter detection and the delayed pulse with each other for determining a change. CONSTITUTION:A clock signal input terminal 5 is connected to a clock rise detector 1 and a clock fall detector 2, and the former is connected to a delaying unit 3, while the delaying unit 3 and the detector 2 are connected to a comparator 4, which is connected to an output terminal 6. When a clock pulse of a period T is inputted to the terminal 5, the detector 1 detects a leading edge and outputs a detection pulse of a pulse width of T2-T1+t, while the detector 2 detects a trailing edge and outputs a detection pulse of a pulse width of (t). The former pulse is delayed by T1 in the delaying unit 3 and both of the pulses are inputted to the comparator 4. The comparator 4 determines whether a DUTY change is within a standard or not and outputs a signal of determination. According to this system, an artificial observation error and nonuniformity in judgement are eliminated and an efficiency of measurement can be improved.

Abstract: PURPOSE:To form high conductivity layers for contacts at a low temperature in a short time by a method wherein compound of semiconductor and metal is employed as the material for the high conductivity layers and the high conductivity layers are formed by a self-matching method. CONSTITUTION:Platinum 9 is deposited to the thickness of approximately 500Angstrom  from nearly direct above to form intermetallic compound, silicide in this constitution. Platinum silicide layers 10 are formed by annealing in an oxygen atmosphere at about 450 deg.C. Following the formation of the platinum silicide layers 10, volume expansion occurs and the undercut under a gate oxide film 3 is filled and the surface of a semiconductor layer 2 comes to almost the same position as the gate oxide film 3. As a platinum silicide layer 10a formed on the gate oxide film 3 is separated from the platinum silicide layers 10 of the source and the drain, a short-circuit between the silicide layer 10a and the silicide layers 10 does not occur. With this method, self-alignment type high conductivity layers for the gate, the drain and the source can be formed.
