Title: Observing method by endoscope device and endoscope
Inventor: SAKAMOTO NOBUYUKI
IPC: G02B23/24
Filed: 1989-04-28
Abstract: PURPOSE:To obtain the endoscope and observing method by which a blurring- free image is obtained even while an inserting part is floated with by the thrust by the injection of jet fluid by emitting stroboscopic light within the charge storage time of a solid-state image pickup element and lighting an observation visual field when a freezing operation means is put in operation. CONSTITUTION:When the inserting part is floated by receiving the thrust with the jet injection of the fluid and the video signal from the CCD 27 of a TV camera 25 is observed on a monitor 33, a switch 37 for freezing is operated when a still image is required. A system controller 34 controls the respective operations of a shutter driving circuit 23, a CCD driving circuit 35, and a stroboscopic light emission driving circuit 41 with the operation signal of the switch to turn on a stroboscopic light emission body 40 within the range of the charge storage time of the solid-state image pickup element CCD, thereby lighting the observation visual field momentarily. Namely, an image is picked up momentarily in the short time much shorter than the original charge storage time of the CCD 27, so even if the inserting part 3 is rocked, the image can be seen in the still state.

Title: Audio signal band split coder
Inventor: IWASAKI SHOICHI
IPC: H03M7/30
Filed: 1992-04-30
Abstract: PURPOSE:To attain coding with high compression efficiency with small size and low power consumption by reducing the arithmetic operation quantity of a high pass filter to eliminate undesired information below a minimum audible frequency. CONSTITUTION:A band split division means 1 divides an audio signal into plural partial bands and outputs a partial band signal. A thinning means 2 thins out the partial band signal for each partial band to output a thinning signal. A high pass filter 3 eliminates a low frequency component from the thinning signal of a minimum frequency part band and outputs a high pass signal. A delay means 4 delays the thinning signal by a time equal to a delay time of the high pass filter 3 for each partial band other than the minimum frequency part band and outputs a delay signal. Then a compression coding means 5 applies compression coding to the high pass signal and the delay signal to output the coding signal. Thus, the arithmetic operation quantity is reduced and the band split coding for an audio signal whose delay characteristic between partial bands is constant with a high compression efficiency is attained.

IPC: B23Q17/09
Filed: 1979-09-03
Abstract: PURPOSE:To detect the abnormality of cutting with high sensitivity, by separating a signal of thermoelectromotive force and a signal of electrical current across a cutting tool and a workpiece. CONSTITUTION:Both ends of a detection resistor R0 coupled in series between the table 2 of a machine tool and an AC power source E0 are connected to a differential amplifier 16. A low-pass filter 17 is coupled to the differential amplifier 16. Another low-pass filter 20 is coupled to the amplifier 16 through a band-pass filter 18 and a rectifier circuit 19. Voltage is applied across the table 2 and an electric contact 7 provided on the central part of the end of a main shaft 5. The magnitude of a circuit current is measured by the detection resistor R0. An AC voltage is applied across a cutting tool 4 and a workpiece 3. A signal of electrical current and a signal of thermoelectromotive force are separated from a signal detected from the detection resistor R0. It is judged from both former separated signals whether cutting is normal abnormal (wear, damage or the like of the cutting tool). Since the signal of  electrical current and the signal of thermoelectromotive force show characteristic  differences as to the normality and abnormality of the cutting, the purpose is attained.

Title: Method for controlling pass position of continuous hot dip metal coating and device for controlling pass position of strip
Inventor: ASAHI ICHIRO
IPC: C23C2/20
Filed: 1989-04-28
Abstract: PURPOSE:To eliminate the deviation in the excitation states of both electromagnet groups by adjusting relatively the neutral points of both the electromagnet groups and the pass position of a strip, thereby preventing the generation of the burn of the electromagnets of both the electromagnet groups. CONSTITUTION:Both the electromagnet groups 2, 3 of the device 1 for controlling the pass position of the strip are mounted by positioning the neutral point SP thereof on a preset pass line PL. Both wiping nozzles 22 are similarly mounted by aligning the intermediate position thereof to the pass line PL. The electromagnet groups 2, 3 are, therefore, not particularly excited for correcting the pass position of the strip S as far as the strip travels on the set PL. The energization of one of the electromagnet groups is consequently indicative of the deviation of the pass position of the strip from the pass line PL. The neutral point of both the electromagnets and the pass position of the strip S are thereupon aligned by moving the electromagnet groups in the thickness direction of the strip S or directly moving the strip in the thickness direction, by which the generation of the burn of the electromagnets by the continuous excitation is prevented.
