Title: Damping control method for printer serving also as paper plate
Inventor: MASUDA SHIZUO
IPC: B41F33/10
Filed: 1991-04-16
Abstract: PURPOSE:To prevent to the utmost scumming and spoilage from occurring by increasing a damping quantity especially a damped quantity on a start of printing also to perform paper plate printing under an excellent damping state by a method wherein a rotary speed of a water fountain roller is increased higher than that in ordinary printing by controlling a nip pressure prior to the start of printing. CONSTITUTION:Before starting printing a nip pressure between a water distributing roller 5 and a water fountain roller 2 is set to be changed so that a delivery quantity of dampening water becomes more than that for a PS plate. When feed of printing paper is started prior to an actual start of printing, a rotary speed of a drive motor for the water fountain roller 2 is increased higher than that in ordinary printing by a motor speed switching means, and a dipping out quantity of damping water is increased greater than that in ordinary printing. The dipping out quantity of dampening water is increased by high speed rotation, and a form roller 6 is moved by control to abut against the water fountain roller 2 of which the delivery quantity has been also increased under a more gentle nip pressure. After holding sufficiently dampening water, the form roller 6 abuts against a printing plate 8 also, supplies dampening water, and printing is started.

Title: Film driving device
Inventor: KONAGAYA MASAHIKO
IPC: G03B21/11
Filed: 1983-09-20
Abstract: PURPOSE:To finish feeding a film in a short time while securing sufficient stop precision even when small number of frames are fed by starting and accelerating the film feed when the frame feed of small number of frames including one frame is started. CONSTITUTION:A control voltage is amplified by a control voltage amplifying circuit 12 and inputted to an operational amplifier 18. The output of the operational amplifier 18 is supplied to a power transistor (TR)19 and a DC motor 1 is driven with the current flowing through the power TR19 to rotate. At this time, the balance of a Wheatstone bridge circuit B is held. When the load on the motor 1 increases, the balance of the Wheatstone bridge circuit B is lost and its output is fed back negatively to hold the constant rotating speed of the motor 1. When a voltage applied to a control input terminal 11 is made zero, the counter electromotive force of the motor 1 is amplified large through a feedback circuit F and a power ampliflying circuit W makes a fast response to stop the motor 1.

IPC: B25J9/22
Filed: 1982-10-01
Abstract: PURPOSE:To teach the coordinate of working point from the drawing of a processed objective with numerical designation by performing prescribed processing in shifting the robbot absolute coordinate to an offset coordinate. CONSTITUTION:An offset value (X0, Y0, theta0) is designated with the numerical designation and stored in the 1st memory. An OF2 point is calculated with the operation and stored in the 1st memory together with an OF1 (X0, Y0). Then, the designation of working point is attained by the numeral designation on the offset coordinates (x, y) and stored in the 2nd memory. Further, the playback to the OF1 or the OF2 is done and when the OF1, OF2 are not suitable after automatic stop, it is corrected. The offset value (X0, Y0, theta0) after correction is obtained and the content of the 1st memory is changed. The playback operation to plural working points is done and if each working point is not suitable, it is corrected. Thus, the coordinate of the working point is taught from the drawing of processed drawing with the numeric designation.

The non-linear waveform of the saw-tooth wave KS provides a predetermined nonlinearity to the input and output characteristics of the duty ratio between the valve control voltage Vx and the valve drive signal DP. This nonlinearity serves to reduce the change rate of the effective combustion quantity Q of a burner 1 relative to the valve control voltage Vx in the zone where the value of Q is small and increase it in the zone where the value of Q is large.

Title: Multifrequency signal receiver
Inventor: AIISO ATSUSHI
IPC: H04L27/26
Filed: 1980-12-10
Abstract: PURPOSE:To reduce the number of used band pass filters considerably, by sampling an input signal and by reading out it by different frequencies and by discriminating the frequency of the input signal on a basis of relations between read frequencies and outputs. CONSTITUTION:An input signal is encoded in an A.D converter 1 by the sampling frequency of 8kHz and is stored in a storage circuit 2. The first pulse generating circuit 71 generates read pulses for reading contents of the storage circuit 2. For read pulses, 228.571kHz, 177.78kHz, 145.455kHz,... are prepared. Only when 228.571kHz is used as read pulses for 700Hz of the input signal, 20kHz is outputted. If the adjustment is so performed that 20kHz is obtained by changing read pulses when the input signal is changed, the frequency of the input signal is detected by read pulses. Therefore, only one band pass filter of 20kHz is required.

Title: Output equalizer for da converter
Inventor: FUJITA KENGO
IPC: H03M1/66
Filed: 1980-12-12
Abstract: PURPOSE:To cancell nonlinear distortion of a DA converter, by applying a DA converter output to an operational amplifier with a feedback circuit having frequency characteristics. CONSTITUTION:When a large amplitude triangle wave deflecting beam is generated at a DA converter, a nonlinear distortion depending on the frequency and amplitude of the triangle wave is produced. This triangle wave is applied to a terminal 2. Since a current I2 is positive when the triangle wave increases, the output voltage is decreased by the current I2, and since a capacitor C is discharged when the triangle wave decreases, the current I2 is negative and the output voltage increases by the I2. As the frequency of the triangle wave increases, the amount of reduction and increase is greater, allowing to cancel said nonlinear distortion.
