Filed: 1984-07-20
Abstract: PURPOSE:To quicken the copying speed while to stop the document reliably by switching the travelling speed of belt for carrying the document in plural steps while controlling said switching such that the document feeding speed go from high to low level. CONSTITUTION:Upon starting of travel of belt 11 for the purpose of document feeding, an electromagnetic clutch 35 is first connected. Consequently, the driving force of motor 12 is transmitted through a larger sprocket 31 to the belt 11 thus to travel it with high speed. Upon detection of the position detecting mark 42 provided on the belt 11 through a sensor 25, said clutch 35 is disconnected while the electromagnetic clutch 39 is connected.

Title: Flat dd motor
Inventor: SAITOU SHIYOUJI
IPC: H02K21/24
Filed: 1982-08-31
Abstract: PURPOSE:To minimize the leakage flux of a flat DD motor by planarly opposing the side surfaces of a stator case and a rotor case. CONSTITUTION:A flat DD motor is composed of a rotational shaft 1, a bearing 2, a support 3, a rotor case 4, a magnet 4, a stator case 6, a PCB7, a coil 8, and a magnet 9 for a tachometer.

Title: Signal transmission method
Inventor: KUSHIMA TATSUYA
IPC: H04Q9/00
Filed: 1994-06-30
Abstract: PURPOSE:To reduce number of poles of a jack by using a signal terminal used to indicate a connection state between an electronic equipment and a display section and a clock input terminal from the electronic equipment in common. CONSTITUTION:The method adopts a sender side (S side) in which terminals of a common cord are connected via a jack and a common code side (R side). When an H level is set to a DATA output terminal 4 to send data representing an operating state of a tape recorder such as data representing what order of music is reproduced at present, a DATA input terminal 11 goes to L via a transistor(TR) 8. Thus, the level of an RDATA input terminal 27 changes from H to L. In this case, an RMUM(I/O) terminal 24 is set to an input state to be a high impedance thereby opening the connection to a terminal 17 substantially. Thus, a serial clock from an SCLK output terminal 1 is fed to an RCLK (clock reception) input terminal 25 via the RCLK input terminal 10 and the terminal 17.

Title: Recording and reproducing device compatible with reinforcing signal
Inventor: KOGA TAKASHI
IPC: H04N7/015
Filed: 1994-07-01
Abstract: PURPOSE:To record or reproduce a signal with high resolution such N as an EDTV-2 system without deterioration by providing an output of a reference signal to apply phase synchronization among an identification signal, a vertical reinforcing signal and a color burst signal of a chrominance signal at reproduction to a luminance signal in the case of Y/C separation. CONSTITUTION:An input video signal 1 is separated into a luminance signal/chrominance signal by a Y/C separator circuit 3 and given to an emphasis circuit 5 and A recording chrominance processing circuit 4 via switches 101,102. Furthermore, the switch 101 is controlled to select a Y output of the circuit 3 for the horizontal blanking period and the switch 102 is controlled to select a C output. A reference voltage 103 is set nearly equal to a voltage so that the circuit 3 provides nearly the same DC current of a chrominance output signal at both positions of the switch 103. The signal is led out to a luminance signal side for periods except the horizontal blanking period. In this system, when a composite signal of the EDTV-2 system is subject to Y/C separation, the reference signal is directly led out to the luminance signal side before a signal required for the luminance signal is separated. Since the reference signal is in existence in the luminance signal side, this system is effective for phase synchronization between the chrominance signal side and the luminance signal side.

Filed: 1985-07-11
Abstract: PURPOSE:To make it possible to stably and uniformly achieve biaxial stretching, by holding a film to specific temp. after stretching in the previous stage and succeedingly stretching the same in the post stage. CONSTITUTION:Polyoxymethylene extruded from an extruder 1 is cooled by a cooling roll 2 to be formed into a raw sheet. Next, this raw sheet is guided to a lateral stretching machine 4 through a rolling machine 3 to be preheated to stretching temp. to be laterally stretched. Thereafter, the temp. of the sheet or film is held to a temp. range from temp. 30 deg.C lower than the peak temp. of the crystal melting curve of the raw sheet measured by a differential calorimeter to temp. 5 deg.C higher than said peak temp. in a temp. holding zone 4'''. The sheet or film reaches a roll 7 through pinch rolls 5, 6 to be preheated to the stretching temp. of the post stage and subsequently stretched on the basis of the longitudinal stretching magnification determined by the rotational speed ratio of stretching rolls 8, 9. By this method, a biaxially stretched film having a high cyristallization degree, a high crystal orientation degree, high rigidity and high dimensional stability can be easily and stably prepared.
