Title: Electronic flashing device
Inventor: TAKAHASHI NAOKI
IPC: G03B15/05
Filed: 1988-09-21
Abstract: PURPOSE:To increase and decrease a flashing amount to a prescribed value intentionally and steadily by restraining the light emission stoppage of a flashing means so that the quantity that a light control circuit emits light plural times during one-frame photographing exposure can increase stepwise when a steady increase in the flashing amount is selected. CONSTITUTION:When photographing start information is inputted, instructions to drive a trigger circuit plural times and to flash the flashing means 8 plural times are given. Simultaneously, the quantity that the flashing means flashes plural times is controlled to increase or decrease steadily, or to reach a prescribed level. The flashing amount setting part of the control means 10 is provided with a setting member 11 instructing the selection of a flashing amount. When light reflected by an object and coming from the flashing means 8 is received to reach the quantity instructed by the flashing amount setting part of the control means 10, the flashing of the flashing means 8 is stopped. Thus, each flashing amount can be changed stepwise by the simple operation when multiflashing photographing is performed, or the flashing means can flash the same light quantity at every stage, thereby expanding the scope of video expression.

Title: Digital dll circuit
Inventor: SHIBAYAMA MITSUFUMI
IPC: G11C11/407
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To provide a digital DLL circuit that locks an input signal correctly even when a phase difference between a reference signal and a feedback signal is large with a shorter lock time and low jitter. SOLUTION: A variable delay circuit 1 is configured with series connection of a rough variable delay circuit 12 where a delay is roughly changed in the unit of a gate delay time and a fine variable delay circuit 12 where a delay is finely changed in the unit less than the gate delay time and the fine variable delay circuit 11 delays a signal in the unit below that of the delay by the rough variable delay circuit 12. In the case that a phase difference between a reference signal and a feedback signal which are given to a phase comparator circuit 2 is large, the delay in the rough variable delay circuit 12 is changed to roughly adjust the delay and in the case that a phase difference between the reference signal and the feedback signal which are given to the phase comparator circuit 2 is small, the delay in the fine variable delay circuit 11 is changed to fine-adjust the delay.  The phase comparator circuit 2 gives numbering to pulses of the reference signal and the feedback signal.

Title: Charged beam device
Inventor: OKUBO TSUNEO
IPC: H01J37/153
Filed: 1984-11-13
Abstract: PURPOSE:To shorten the working distance and reduce the aberration by using multielectrode lenses as a focusing element and installing deflectors in the position where part of the deflecting field overlaps the focusing field. CONSTITUTION:An electron beam 109 from an electron gun 101 is accelerated by printing voltage applied across the electron gun 101 and an anode 102 and then the accelerated electron beam 109 is image on a first formation aperture 104 by means of an irradiation lens 103. Next, the thus produced image is projected upon a second formation aperture 106 by means of three-stage tetrode terminal lenses installed in a formation system 105. The position on the aperture 106 upon which the image is projected is changed by two-stage tetrode deflectors installed in the formation system 105. Thus, a variable formed beam is produced by changing the length of each side of the rectangular beam. The rectangular image on the aperture 10 is reduced and projected upon a sample 108 by means of three-stage tetrode lenses installed in a deflection system 107. The position on the sample 108 upon which the image is projected is changed by two-stage tetrode deflectors installed in the deflection system 107. Reduction of the aberration can be achieved by thus incorporating the deflectors into the lens system.

Title: Electronic micro scanner
Inventor: KADOI HARUO
IPC: H04N1/04
Filed: 1984-11-13
Abstract: PURPOSE:To display continuously an optional picture region on a microfilm or record continuously it on a optical recording medium by increasing the film feeding speed at a location except the film picture reading to segment and collect the picture region without using a memory. CONSTITUTION:In displaying head picture regions (a, b) of, e.g., frames 22, 24 onto a display device in the lump, a film 21 is fast by a feeding roller 12, a frame detection mark is detected by a photodetector 65, and when an objective frame is found out, the film feeding speed is decreased, the film 21 is fed to a speed v1 synchronously with the reading speed of a solid-state image pickup element 19 to read the head (a) of the frame 22. When the read is finished, the speed of the feeding roller 12 is increased again to feed the film 21 at a speed v2, and when the next frame 24 is detected, the film feeding speed is decreased to the v1, and the image pickup element 19 reads the head (b). When the said read is finished, the film is fed in the speed v2 again to seek the next designated frame. The operation device above is repeated.

Title: Synchronizing signal reproducing device for television signal
Inventor: MORIKAWA YASUHIRO
IPC: H04N5/08
Filed: 1990-09-06
Abstract: PURPOSE:To eliminate jitter component by counting a period of an inputted synchronizing signal with a sampling pulse, discriminating whether or not the period of a succeeding synchronizing signal is a regular period based on the count and generating a synchronizing signal based on a pulse signal generated when the count reaches a regular count in the case of the regular period. CONSTITUTION:A sampling device 1 outputs a horizontal synchronizing signal (c) resulting sampling an inputted horizontal synchronizing signal (b) and a differentiating device 2 outputs a differentiating signal (d) of the horizontal synchronizing signal (c). A phase comparator 3 compares a phase of the differentiating signal (d) with a phase of an output signal from a numeral discriminator 6 to output a control signal (g). A switch 7 is controlled by the control signal (g) to select an output pulse (h) of a numeral converter 5 for a period of an H level and a horizontal synchronizing signal generating circuit 9 outputs a horizontal synchronizing signal (k) with a prescribed width synchronously with a starting of an output signal (i) from the switch 7. Thus, even when a change point of the input horizontal synchronizing signal and a change point of a sampling pulse are close to each other, a synchronizing signal whose horizontal synchronizing signal does not include a jitter component is reproduced without provision of a phase adjustment circuit.

Title: Receiver for digital broadcasting
Inventor: ITAYA TAKESHI
IPC: H03D7/18
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To provide a receiver of simple constitution capable of suppressing the interference of reception by easily removing an image signal from a received digital broadcasting signal. SOLUTION: The down converting circuit 5b of this receiver 1 is made to be an image rejection type mixer. The desired signal of a frequency fD outputted from a high frequency amplifier circuit 4 is inputted to the circuit 5b to be mixed with the oscillation signal of a frequency fL0 from a local oscillator 5a to generate low IF(intermediate frequency) of a frequency fIF=fL0-fD. On the other hand, an image signal with an image frequency fIM inputted to the circuit 5b is shifted to a frequency fIM+fL0 to being removed state. Since the signal of the frequency fIM+fL0 is sufficiently separated from a frequency fIF of low IF compared with the image frequency fIM, frequency components related with the image signal is completely removed by passing through a band pass filter 6 of a poststage.

IPC: H03G3/30
Filed: 1995-08-24
Abstract: PROBLEM TO BE SOLVED: To reduce the distortion of an output signal by switching a control voltage generating circuit when the output signal level of a prescribed multiplier is changed and sending an output from a control voltage generating circuit having a smaller time constant to the multiplier. SOLUTION: An input signal is amplified by a variable gain amplifier 1, an output from the amplifier 1 is amplified by respective multipliers 2, 3. The gain of the amplifier 1 and that of the multiplier 2 are controlled, based on an output from a control voltage generating circuit 4 receiving an output signal from the multiplier 2 and controls the output level of the multiplier 2 to a prescribed level. The time constant of a control voltage generating circuit 5 for controlling the output signal level of the multiplier 3 at the reception of an output signal from the multiplier 3 is set smaller than that of the circuit 4.  When the output signal level of the multiplier 2 is changed, the output of the circuit 4 is switched to the output of the circuit 5 by switch circuits 7, 8, and the output of the circuit 5 is sent to the multipler 3 and the output of the multiplier 3 is sent instead of the output of the multiplier 2.

Title: Optical device
Inventor: SHIBATA SATOSHI
IPC: G11B7/08
Filed: 1991-09-18
Abstract: PURPOSE:To provide the optical device which thermally expands and shrinks the base part for fixing the optical parts by an environmental change, such as temp. change, and can surely fix the optical parts without deforming the optical parts even if external force is applied to the optical parts. CONSTITUTION:An adhesive is applied atop an adhesive part 5 to adhere the base of the thick part exclusive of the front end 4 of a triangular prism 3 and to simultaneously join the base of the thin front end 4 to a joint part 6, by which the triangular prism 1 is fixed. Further, the adhesive part 5 and the joint part 6 are segmented by a groove part 7. The base part 2 is, therefore, thermally expanded and shrunk and the direct propagation of the external force to the front end 4 is obviated even if the external force is applied on the triangular prism 1. The adhesive part 5 is large in the wall thickness and is, therefore, not deformed by the external force. The triangular prism 1 is surely fixed in this way.

Title: Video recorder, video recording method and video recording medium
Inventor: ITO MASANORI
IPC: H04N19/91
Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To keep an average rate while suppressing the deterioration of picture quality by storing an assignable code amount with the fixed bit rate of rate setting lower than a target value when difficulty in compression is within a prescribed range and performing variable rate compression control by consuming the stored code amount when difficulty in compression is larger than the prescribed range. SOLUTION: A rate control switching part 16 detects the generated code amount of a Huffman encoding part 104 and switches a fixed rate compression control part 107 or variable rate compression control part 108 with the upper limit and lower limit of a threshold value as references. According to difficulty in the compression of video, the variable rate compression control part 108 controls the generated code amount and matches the average rate to a target rate in a cycle longer than an average rate control unit. The fixed rate compression control part 107 stores the assignable code amount by performing control for each frame number of the average rate control unit so that average rate of the generated code amount can be 90% in the target rate, for example.

Filed: 1984-11-13
Abstract: PURPOSE:To simplify the circuit constitution and cost-down by detecting the absence of a 19kHz stereo pilot signal, presence of subcarrier and locking of an FM detection circuit of a PLL system and regarding the said detection as the reception of a television sound multiplex signal. CONSTITUTION:Since the 19kHz stereo pilot signal does not exist, the sub carrier exists and the FM detection circuit 27 of the PLL system is in locking state at the reception of a television sound multiplex signal, all inputs to an AND gate 35 are logical H and an output of the AND gate 35 is logical H. Thus, a bias is applied to a buffer transistor (TR)28 and a polarity inverting TR29 and an output of the FM detection circuit 27 is given to a base of the polarity inverting TR29 via the buffer TR28, a de-emphasis circuit 49 and a low passfilter 50. Since the output of logical H of the AND gate 35 is fed to the 1st switch 40 as an operating power supply, the 1st-4th switch circuits 25-34 are switched depending on the state of the 1st switch 40.
