Title: Phase comparator circuit
IPC: H03K5/26
Filed: 1992-03-27
Abstract: PURPOSE:To provide the phase comparator of an optical frequency offset lock loop which is used in a transmission equipment or a coherent light measuring instrument on an optical wave communication network by detecting the sign of the frequency difference between first and second input signals. CONSTITUTION:If the output of a pulse number difference counting means 3 which subtracts the number of pulses of the second input signal from that of the first input signal to calculate the difference between them is larger than a prescribed upper limit value by an upper limit value detecting means 4 which compares the output of the means 3 with this upper limit value, a first switch 1 breaks the first input signal. If the output of the pulse number difference counting means 3 is smaller than a prescribed lower limit value by a lower limit value detecting means 5 which compares the output of the means 3 with this lower limit value, a second switch 2 breaks the second input signal. An analog signal conversion means 6 converts the output of the pulse number difference counting means 3 to an analog signal. Consequently, this circuit is operated as a phase frequency comparator(PFC) which outputs the output corresponding to the sign of the frequency difference.

Title: Toner recovering device of electrophotographic copying machine
Inventor: ASAHINA YASUO
IPC: G03G21/10
Filed: 1983-04-25
Abstract: PURPOSE:To stabilize the polarity of a toner with frictional electrostatic charge by coating the surface of a carrying member, which recovers the toner remaining on a photosensitive body into a developing part, with a material which is higher or lower than the toner in the electrostatical charge sequence. CONSTITUTION:A surface 20a of a toner discharging auger 20 which recovers the toner scraped from the photosensitive body and gathered in a discharging part into a toner supply tank of a developing part is covered with the material which is higher or lower than the toner in the electrostatic charge sequence. Therefore, when a toner 21 is carried by the discharging auger 20, the toner 21 is electrostatically charged with a stable polarity by frictional electrostatic charge between the toner 21 and the surface of the discharging auger and is recovered into the developing part. Thus, ground soiling and the scattering of the toner due to lack of the electrostatic charge are prevented even if the toner 21 is used again.

Title: Device and method for correcting parallax of finder
IPC: G03B13/14
Filed: 1992-03-27
Abstract: PURPOSE:To obtain the finder parallax correction device capable of approaching the center of the visual field of the finder of a proximity photographing time to the photographing center of a photographing lens while satisfying a performance with excellent visual field. CONSTITUTION:A visual field frame member 8 arranged on the optical axis of a finder optical system 1 is constituted of a pair of plate materials 12 and 13 whose inside are cut in a prescribed visual field frame state so that the parallax of the finder is corrected by such a method that the visual field is changed by moving one plate material 13 at the proximity photographing time with respect to the normal photographing time and the maximum viewing angle of the proximity photographing time is prevented from exceeding the maximum viewing angle of the visual field of the normal photographing time. Thus, since the center of the visual field of the finder of the proximity photographing time can be made to approach the photographing center of the photographing lens, the parallax of the contact photographing time can be corrected with the simple constitution.

Title: Optical axis adjustment method of vehicle detecting device
Inventor: TOYAMA KOICHI
IPC: G01B11/00
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To maintain high resolution, and at the same time to allow adjustment with a small number of man-hours, by using an optical axis that can be effectively used for detection as it is, and by adjusting only a part where specifications cannot be met while a vehicle detecting device is installed. SOLUTION: In the optical axis adjustment of a vehicle detecting device, the optical axis is adjusted so that the minimum detection distance from a road surface is met and then necessary resolution is met. For example, the usable light emitting equipment at the lowest stage is selected by judging whether light emitting equipment can be used starting from the lowest stage successively by a specific method. For the light emitting equipment, the effective optical axis at the lowest stage is obtained, and it is judged whether the optical axis satisfies the request of the shortest distance from a road surface. When the request is not met, the directions of the light emitting equipment and a light receiver where the lowest effective optical axis becomes lower are adjusted.  Then, the effective optical axis for detection that meets resolution requirement is successively selected from the bottom. When all of the effective optical axes for detection that meet the resolution requirement cannot be selected, the directions of the light emitting equipment and the light receiver regarding a position that cannot be selected are adjusted.

Title: System for mixing intefering wave to specified channel in catv system
Inventor: KANEKO SHOHEI
IPC: H04N7/16
Filed: 1985-04-04
Abstract: PURPOSE:To completely breakdown both of a sound and an image by one interfering wave by providing an interfering wave mixing device at an intermediate position between a cable and a terminal, generating the interfering wave corresponded with a video signal in time division and changing the insertion period of the interferring wave. CONSTITUTION:An interference T2 having a short period is mainly used for the breakdown of the image and an interference T1 having a long period is mainly used for the breakdown of the sound. As for the interference T1 having the long period, 1/T1=50-200Hz generates the best sound scrambling. This is because that, in an audible wave period 20-200kHz, the wave having a low frequency becomes to be a noise. The timbre in a sound interference is varied by changing the 1/T1. Also, the sousnd volume of a sound interfering tone is varied by a t1 and the longer the t1, the larger an interfering tone and the shorter the t1, the smaller the interferring tone. Considering the switching speed of an RF switch, the longer a t2, the better and the more a channel number, the better. Also, when the t2 is set at the level by an integer-times of a horizontal synchronization, the largest effect of an image scrambling is obtained.

Title: Thrust-off control system
Inventor: MATSUMOTO FUMIO
IPC: G06F17/40
Filed: 1985-04-04
Abstract: PURPOSE:To prevent a soft overrun when the analyzing result, etc., of the collecting data are periodically displayed by counting the output completion signal generated for the output period each, and starting the data processing device when the counted value arrives at the prescribed number. CONSTITUTION:A CPU 6 retrieves a command memory 14, analyzes the designated collecting data, stores them to a displaying data buffer 8, and thereafter, the output command is sent to a channel part 21. The channel part 21 repeatedly reads and outputs the contents of the displaying data buffer 8, and sends the output completing signal each time the output is completed. An interruption monitoring part 21 counts the output completing signal by an interrupting counter 21a, counts the prescribed number and thereafter, sends the interrupting signal to the CPU 6. Thus, the CPU 6 retrieves the command memory 14, executes the continuous command, and in case of the completing command, an output completing command is sent and the displaying output is completed.
