Title: Device for recording/reproducing signal
Inventor: KURANO YUKIO
IPC: H04N5/92
Filed: 1993-11-18
Abstract: PURPOSE:To provide a reproducing picture with high picture quality at the time of high speed reproduction. CONSTITUTION:A video signal inputted from an input terminal 4 is outputted to a modulator 7. In the modulator 7, the inputted data are modulated to be outputted to a recording/reproducing head 9. Further, the transmission rate of the video signal inputted from the input terminal 5 is inputted to a drive control circuit 13. In the drive control circuit 13, the transmission rate of the video signal is recognized, and a magnetic tape is fed at a 6mm/s tape feeding speed of 1/3 of the tape feeding speed in the case of the signal with the 24Mbps transmission rate. At this time, the data of its time base compressed to 1/3 are recorded on the magnetic tape 12 only for a once scanning period among the time when the recording/reproducing head 9 scans the magnetic tape 12 by three times, and for remaining two times scanning periods, the null recording for recording no data is performed. Thus, a data rate recorded on the magnetic tape 12 becomes similar to 24Mbps being three times at a transmitting time.

IPC: G02B23/24
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To strongly fix a treatment tool inserting tube to a connecting pipe by using an adhesive by provided an activated surface against the adhesive to the inner surface of the treatment tool inserting tube which is made of a fluorine resin layer whose inside surface is smooth and whose frictional coefficient is small. SOLUTION: In the treatment tool inserting tube 20 made up of an inner layer 21 of a nonporous fluorine resin layer which is smooth and whose frictional coefficient is small, an intermediate layer 22 of a reinforcing layer consisting of a net, and an outer layer 23 of urethane resin such as a soft polyurethane, a large part of the fitting part of the inner layer 21 thereof to a connecting pipe 10 is formed by an activated surface R which is subjected to activated treatment against the adhesive by means of etching treatment, and an adhesive 24 is interposed therebetween. Thus, when the treatment tool inserting tube 20 is fitted to the connecting pipe 10, the adhesive force due to the chemical bonding between the adhesive 24 and the activated surface R of the inner layer 21 is developed, so that the adhesive strength therebetween can be greatly enhanced.

Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To improve the durability and the life, by stacking a lubricant permeation inhibitor which is elastically deformable, and has the lubricant permeation inhibiting property higher than that of a boot body, on at least a part of the boot body. SOLUTION: A flexible boot 22 comprises a boot body 28, and a thin film- type lubricant permeation inhibitor 29 buried inside of the boot body 28, and both are integrated by the vulcanization adhesion, and applied to the whole periphery of the boot 22. The material of the boot body 28 is elastically deformable, and comprises the function for sealing the grease, and chloroprene rubber, polyethylene or the like can be used. The material of the lubricant permeation inhibitor 29 is elastically deformable, and has high grease permeation inhibiting property higher than that of the boot body 28, and polysulfide rubber, thermal contracting polyethylene or the like can be used.  The permeation inhibitor 29 hardly permeates even when the grease permeates into the boot body 28 becuase of the increase of the internal pressure of a lubricating chamber 24, so that the boot 22 can stably keep the grease sealing function for a long period.

IPC: H03L7/08
Filed: 1991-10-09
Abstract: PURPOSE:To obtain an oscillation output with a prescribed frequency without dispersion by setting a digital signal stored in a memory to a value by which the dispersion substantial to a voltage controlled oscillator is corrected. CONSTITUTION:A digital signal corresponding to a control voltage by which a phase of an output signal of a voltage controlled oscillator 1 is made the same as a reference signal is stored in a memory 3 in an oscillation circuit in an oscillating frequency adjustment circuit. Thus, a digital signal corresponding to a control voltage correcting the dispersion in the oscillating frequency of the oscillator 1 is stored in the memory 3. A digital signal in the lock state stored in the memory 3 is D/A-converted by closing a switch 9 in the oscillation circuit comprising the oscillator 1, a D/A converter 2 and the memory 3 and inputted to the oscillator 1. Then a save frequency signal as the reference signal is outputted. Thus, even when the oscillating frequency of the oscillator 1 has a dispersion, the frequency signal equal to the reference signal is obtained by combining the oscillating frequency adjustment circuit and the oscillation circuit and adjusting them.

Title: Rigid endoscope
Inventor: SHIBUYA SHOZO
IPC: G02B23/26
Filed: 1987-11-16
Abstract: PURPOSE:To eliminate need for moving substantially and to allow an operator to observe in a comfortable position by providing the turning axis of an eye contact part parallel to the axis of an insertion part. CONSTITUTION:The turnable axis of the eye contact part 14 is formed in parallel with the insertion part 12. Therefore, the rotation of the eye contact part 14 is parallel to the axial direction of the insertion part 12. Since the part 14 is protrusively formed in the oblique direction and not perpendicular to the axial direction of the insertion part of the eye contact part 14, the eyes of an operator peeping through an eye contact cover need not move greatly. Thereby the endoscope is more easy-to-handle.

Title: Image forming device and cleaning-blade replacement method
Inventor: TSUKAMURA SHINICHI
IPC: G03G21/10
Filed: 1998-10-13
Abstract: PROBLEM TO BE SOLVED: To prevent a problem which occurs in a blade and, further, to shorten job time required for replacement, by controlling an image carrier and a developing means so that toner is attached to the image carrier when a device judges that replacement is necessary. SOLUTION: When a copy job is finished with a blade-replacement necessity judgment circuit 13b judging that blade replacement is necessary, a main control circuit 13c turns on a toner attachment signal. At the same time as it, the supply of drive by a drum drive motor 40 is stopped, therefore the drive of the photoreceptor 2 is turned off, and the photoreceptor 2 starts idle rotation, gradually decelerates, and stops. Positive charges by an electrification electrode 3 are not applied to the idly rotating photoreceptor 2 after the erasure/ uniformization of residual potential by electrification exposure part 12. However, toner is positively charged by stir in a developing unit 5, therefore by applying a development bias to a sleeve 5a, the toner is attached to the surface of the photoreceptor 2 even with no positive charges applied to the photoreceptor 2.
