Title: Processor for analog signal
Inventor: DONARUDO HENRII UIRISU
IPC: H04N9/455
Filed: 1985-12-02
Abstract: a A narrow bandwidth analog-to-digital conversion (ADC) system is described in the context of the color burst processing and burst phase detecting circuitry of a digital color television receiver. The ADC (14) includes a dither generator which adds a dither signal to either the analog input signal (10) or to the reference signal (38) used by the ADC. This dither signal increases in magnitude by 1/16 of an LSB value at a rate one-quarter of the burst frequency and changes in sign at one-half of the burst frequency. This signal passes through a low-pass filter (18) in the chrominance channel providing an increase in sample resolution by averaging the samples in a chroma band-pass filter and in the phase detecting circuitry (30).

Title: Connector receiving jig
Inventor: TAKAYANAGI TAMAKI
IPC: B60R16/02
Filed: 1993-11-02
Abstract: PURPOSE:To enhance workability by allowing movement of a connector with respect to insertion into the inner surfaces of side walls of an insertion port, and inhibiting the movement in the wire harness introducing-out direction. CONSTITUTION:When a connector 1 is engaged with cam surfaces 42 of connector locking members 40, the locking members 40 are turned outward against energizing force of springs 46 around axes 44 by pushing force of the connector 1, which is contained in a connector receiving member 30 with allowable insertion. If tensile force is exerted on the connector 1 to draw it toward the wire harness introducing-out direction, the locking members 40 are slightly turned inward by the energizing force of the springs 46, and then, hold the connector 1 therebetween in cooperation of the springs 46 with the cam surfaces 42, thus inhibiting the movement in the drawing direction. When the connector 1 is inserted into the receiving member 30, it can be inserted with allowable movement. Consequently, if tensile force is exerted on the introducing-out force of the housed connector 1, the locking members 40 act to inhibit the movement so as to prevent falling-out, thereby enhancing workability.

IPC: B65H7/20
Filed: 1991-09-26
Abstract: PURPOSE:To absorb a timing advance/delay generated in feeding sheets in the middle of transport, and decrease an interval between the sheets by setting a transport speed changeable in the middle of the sheet transport. CONSTITUTION:Taking a sheet discharged from a tray 40a by a pickup roller 42 to be on stand-by close to a separation roller pair 44a as a reference, a target timing for the sheet to pass a second position 68 downstream of a first position 46a is preliminarily set. The sheet is sent from the separation roller pair 44a, a timing at which the sheet passes the first position in a transport path is detected by a sending detection sensor 46a, and a difference between a detection result and the target timing is computed by a CPU 72. A sheet feed speed is controlled by a control means 70 based on this difference so that the sheet may reach the second position at the target timing. A delay from the reference timing generated at the separation means is thus absorbed in the middle of transport, and the sheet reaches the second position at the predetermined timing with a predetermined sheet interval.
