Title: Fixing device
Inventor: INAGAKI SATORU
IPC: G03G15/00
Filed: 1983-11-17
Abstract: PURPOSE:To prevent the generation of a crease even if a recording paper whose front end is curled is introduced, by applying a bias voltage to a guide member provided near a fixing nip part to introduce the recording paper to a roll fuser part while attracting the front end of the recording paper. CONSTITUTION:A bias voltage is applied from a power source 14 to a lower guide plate 7 provided near a pressure roll 10, and an upper guide plate 8 is grounded, and then, the electric field going from the plate 7 toward the plate 8 is generated to generate a force which attracts the recording paper downward. Since a sent recording paper 1 is attracted to the guide plate 7, the front end is straightened even if it is curled, and the recording paper is introduced to a roll fuser part 11 between a heat roll 9 and the pressure roll 10, and the center part and corner parts of the front end of the paper 1 are taken into a fixing nip area 2 simultaneously. Consequently, the generation of a crease is prevented even if the recording paper whose front end is curled is introduced.

Title: Displacement measuring circuit
Inventor: ORII SATORU
IPC: G01B7/00
Filed: 1985-09-30
Abstract: PURPOSE:To enable highly accurate measurement with a simple circuitry, by measuring time without any phase and cycle measurement. CONSTITUTION:A relative displacement between moving objects is detected and converted into a phase modulation signal with a temperature amplification circuit 28 or the like. A transmitter 23 obtains a signal of N notation with the frequency corresponding to the phase modulation signal. An N notation time counting circuit 31 for counting time by this signal, a memory circuit 32 for memorizing a value of this circuit and a memory signal generation circuit 33 for providing a fixed position of the phase modulation signal to the circuit 32 as memory signal are arranged and an arithmetic processing is performed with an arithmetic processing circuit 34 upon receiving a outputs of the circuits 32 and 33 as input. In other words, when a value tn of the circuit 32 at a cycle (n) and a value n+1 at the subsequent cycle are set at tn+1 and the maximum displacement from the cycle n to the subsequent cycle n+1 is less than + or -N/2, an arithmetic processing for discrimination is performed from the formulas (wherein Xn: relative displacement, N: integer as interpolation value and S: code opposite to Xt+1-=Xt) to determine the relative displacement Xn.

Title: Jitter measuring signal detector
Inventor: SHIMADA TOSHIYUKI
IPC: G11B7/24097
Filed: 1987-08-31
Abstract: PURPOSE:To measure the jitter of a spindle motor with high accuracy and a high band by suppressing the decentering information with a reference signal provided at a reference signal. CONSTITUTION:A reference disk 1 for measuring a jitter having a triangular shape mark 10 is fitted to a spindle motor 2 to be measured and rotated in a measuring condition. A photodetector 3 detects the mark 10, a detecting signal is pulse width/voltage-converted, binarized by a processing part 4, and the output which resets a counter 5 is given to a D/A converter 8 as a clock. The counted value of the output of an oscillator 6 is supplied from the counter 5 to a subtracter 7 and the difference in a reference pulse width Tr is D/A- converted 8 and outputted through an LPF9. As this result, the number of the marks of the disk 1 and the decentering information accompanying the change of the duty of the detecting output are simultaneously detected, the jitter quantity due to the decentering is calculated backwards, subtracted from the number of the detections of marks, and thus, the jitter measurement of the spindle motor is executed.

Title: Camera with focus detecting device
Inventor: AKASHI AKIRA
IPC: G03B13/36
Filed: 1988-08-31
Abstract: PURPOSE:To accomplish focus detecting process with proper responsiveness by using a non- destructive read sensor in which an electric charge accumulated at reading a photoelectric conversion signal is stored and again reading the photoelectric conversion signal after a definite time without resetting the electric charge of a photoelectric conversion element part if the size of the read photoelectric conversion signal is not proper. CONSTITUTION:Pairs of sensor trains SNSI1 and SNSI2 extract the light quantity distribution of an object in a longitudinal direction. Reversely, pairs of sensor trains SNSO1 and SNSO2 can respond to various patterns of the object for extracting the light quantity distribution in a vertical direction. Besides, since the baseline length of secondary optical systems MO1 and MO2 in the longitudinal direction is long compared with the baseline length of secondary optical systems MI1 and MI2 in the vertical direction, in an identical defocus, the relative position displacement quantity of the object image in the longitudinal direction is bigger. Therefore, focus detection in the longitudinal direction is high in accuracy compared with the focus detection in the vertical direction. Reversely in the vertical direction, since the relative displacement quantity is small, if position displacement quantity to be detected is equal to the position displacement quantity in the longitudinal direction, defocus quantity to be detected is big compared with the defocus quantity in the longitudinal direction. Thus, the focus detecting process with proper responsiveness can be accomplished.
