Filed: 1986-12-15
Abstract: PURPOSE:To easily perform the constant current control in the primary side by controlling the output current to a constant current by the control which fixes the product between an input voltage to a converter and the conversion frequency of the converter. CONSTITUTION:The DC input voltage to an inverter circuit is inputted to a switching circuit 30 also and is switched there by a driving pulse signal which has prescribed relations to the driving signal to the inverter circuit. The output signal of the switching circuit 30 is smoothed by a smoothing circuit 62 to obtain an average value, and it is inputted to an error amplifying circuit 34. An output voltage V1 is compared with a reference voltage Vref, and a voltage corresponding to the deviation is outputted to a voltage-frequency converting circuit 36. The output signal of this circuit is outputted to a driving width setting circuit 38, and a driving signal VDRV and a driving pulse signal VP are outputted from this circuit 38 at a period corresponding to the output signal from the voltage-frequency converting circuit 36, and the conversion frequency of the converter is controlled by the driving signal VDRV. That is, the control to fix the output voltage V1 is performed.

Title: Facsimile equipment
Inventor: KAMIMURA TETSUYA
IPC: H04N1/387
Filed: 1993-11-30
Abstract: PURPOSE:To eliminate the need for caring a time difference from a sender by receiving transmission time information converted into a destination local time when facsimile data are relayed and sent to the destination of another country. CONSTITUTION:When relay transmission of facsimile data is conducted and if a destination is decided to be a destination in another country, an OMR recognition section 4 and a system control section 7 retrieve a destination country from the user information such as a facsimile number and a user registration number stored in a user information storage section 11. At the time of transmission the section 7 converts the transmission time to a destination local time based on the result discriminated by the recognition section 4 and the control section 7. The result of conversion is added to a header, a cover page and a reception notice by an image processing section 3, and the result is received by the destination together with the received storage document stored in a data storage section 5. Thus, a recipient receives the transmission notice without conversion of the time difference from the sender.

Filed: 1987-11-27
Abstract: PURPOSE:To prevent an error in operation by determining abnormal conveyance if first and second detecting means for detecting a bundle of paper sheets on conveyance in different detecting areas, detect the same, simultaneously or within a predetermined time period. CONSTITUTION:A bundle P0 of banknotes bundled in a band applying section is dropped from a carrier onto a belt 15, and is conveyed after being detected by a second detecting means 8. Then, the bundle of banknotes is discharged into a storage means 2 through a first detecting means 5. When the second detecting means 8 detects an abnormal banknote P1, the first detecting means 5 detects the preceding bundle P0 and issues a detection signal, simultaneously, and accordingly, an abnormal alarm is produced. Further, if both detecting means 5, 8 deliver detection signals with a timing shorter than a predetermined value, and an abnormal alarm is similarly produced. Further, when a comparative number of bundles P0 are stacked in the storage means 2, and are retained on the first detecting means 5, both detecting means 5, 8 deliver detection signals, simultaneously, a full alarm is produced. Thus, it is possible to precisely know an abnormal condition.

Title: Outer tape winding method for wire harness
Inventor: KUSUMOTO KUNIHARU
IPC: B60R16/02
Filed: 1989-11-17
Abstract: PURPOSE:To maintain flexibility of a wire harness by inserting a jig into a plurality of electric wires, winding tapes on a bundle of the electric wires, and pulling out the jig. CONSTITUTION:After a jig 5 is inserted into a bundle of electric wires 4 and tapes are wound on the bundle, the jig 5 is pulled out to form an empty space 7 in the bundle of the electric wires 4. By this method, while the most outer layer of the bundle of the electric wires becomes fixed condition with high adhesion strength, each wire of an electric wire group in the inner layer can move freely each other, especially, toward parallel direction to the electric wire, which is a longitudinal direction, since the empty space 7 is formed in the inner layer of the electric wire group. While maintaining adhesion strength between tapes each other, electric wires inside of the wire harness wound with tapes can be loosened by untwisting the wire harness several times. In this way, flexibility of a wire harness can be maintained.

IPC: B65H19/10
Filed: 1995-10-25
Abstract: PURPOSE: To prevent the operation rate of a web supply device from decreasing so as to reduce the loss of webs by operating a protective material peeling means according to a signal indicating the detection of a reduction in the diameter of a rolled web being consumed to a predetermined diameter slightly before splicing is made by sticking. CONSTITUTION: A reduction in the diameter of rolled paper R being consumed in advance to a predetermined diameter is detected by a known means, e.g. a means which detects this reduction in terms of the relation between the consuming speed of a downstream device consuming the rolled paper R and the number of revolutions of a roll support member 12 supporting the rolled paper R being consumed, the number of revolutions matching the consumption of the rolled paper; when a signal indicating the detection is output, a brake- mechanism-equipped hydraulic pressure cylinder 403 operates, bringing a second frame 420 and all the associated members close to the peripheral surface of the rolled paper R.  This movement leads to the slow rotation of the roll support member 12, and at the detection of a predetermined mark on the peripheral surface of the rolled paper R the member 12 is locked according to a signal indicating the detection. Then the suction part of a peeling device 4 is made to suck the surface of a protective material and is swinged so as to be separated, thus peeling the protective material.
