Abstract: PURPOSE: To inexpensively manufacture a flexible image guide by sticking triple optical fibers each having a jacket of acid-soluble glass to each other to form a preform, heating and drawing the preform, and subjecting the resulting bundle of optical fibers to acid leaching.  
     CONSTITUTION: A prescribed number of triple optical fibers each consisting of a core, a clad and a jacket of acid-soluble glass are stuck to each other with an org. adhesive to form a preform having the shape of a light guide. The preform is fed into an electric furnace 16 with rollers 14, heated to about 700°C, and drawn with rollers 15 to obtain a bundle 17 of optical fibers. In this stage the adhesive is removed, and the outside diameter is reduced to about 1/15. The bundle 17 is cut, and after sealing both ends with an acid resistant resin 20, the bundle is put in an acid leaching vessel 21, where the acid-soluble glass forming the jackets is dissolved in nitric acid 19. Thus, a flexible bundle of fibers for a light guide can be manufactured in such simple stages.

IPC: G03G15/08
Filed: 1985-04-24
Abstract: PURPOSE:To prevent a copying machine from copying with low density by forming a toner empty detecting sensor to detect the state that the volume of toner in a toner feeding bottle is reduced less than a prescribed level land to delay the working of a copying operation control means. CONSTITUTION:An original is set up on an original glass 2 and scanned by a scanning optical system including a projection lens L and an original image is projected on a photosensitive drum 5 to form an electrostatic latent image. Then, toner is fed from a developing device 10 to develop the electrostatic latent image. The toner feeding bottle is fitted to the developing devie 10 and the toner empty detecting sensor 50 is fitted to the bottle. The detecting sensor 50 detects that the volume of the toner is reduced less than the prescribed level and sends a signal to the copying operation control means to delay the feeding operation of the toner. Said signal is also transmitted to a display part for displaying the number of copies to display the empty state of toner. Consequently, the copying machine is prevented from copying with low density due to the lack of toner.

IPC: B65D81/18
Filed: 1989-04-08
Abstract: PURPOSE:To improve the insulating performance by using a porous body as heat insulating material in combination with a heating body. CONSTITUTION:A porous body made of fine particles is used as heat insulating material 3 in combination with a heating body 8. Owing to an exceedingly low heat conductivity at normal temperature and pressure resulting from such porous structure of the heat insulating material 3, the subject container provides a high insulating performance even in a small thickness and can be preheated or reheated by the heating body 8. This permits the insulating performance to be improved and the performance deterioration with the passage of time to be decreased. Light in weight and small in size, this container is portable and can be given a square shape freely.

Abstract: PURPOSE:To ensure an A/D convertion with high accuracy and good linearity, by setting a compensating capacitor between an optional resistance joint and the earth of a circuit network that produces the reference voltage and accordingly suppressing the voltage variance of a reference-voltage generating terminal. CONSTITUTION:Resistances 21-28 are connected in cascase to a reference- voltage generating part that applies a reference voltage to a comparator. Application voltages VMAX and VMIN are applied between terminals of the resistances 21-28. The voltage divided by each of the resistances 21-28 is applied to a comparator using an analog signal for its input in the form of the reference voltage. The compensating capacitors 71-79 are connected between the earth and the resistance joints of the resistances 21-28 and a joint between the voltages VMAX and VMIN. When the variance of voltage is suppressed for the generating terminals of the reference voltages V1-V7. When the number of input bits is large, each resistance is divided into resistance blocks 81 and 82-816. Then the compensating capacitors 71 and 72-717 are provided to the blocks 81 and 82-816, respectively. Thus the variance is suppressed for the voltages V1 and V2-V17 which are applied to the comparators, respectively.

Abstract: PURPOSE: To increase a search speed by realizing accurate signal detection by making the search speed the best in an intermediate band and slower in low and high bands.  
     CONSTITUTION: Once dividing ratio (n) is supplied from control circuit 7 to programmable counter 52, an oscillation frequency from VCO51 is diveced by (n). Then, PLL frequency synthesizer 5 is locked after constant time elapses and the locking of dividing ratio (n) is done. Lock detection circuit 11 exercises supervision over phase detector 54 and when a phase difference is elemiminated between frequency outputs of counter 52 and reference oscillator 53, it is judged that lock detection circuit 11 is in a locking state, thereby sending signals out to control circuit 7. In this locking state, a local oscillation frequency is supplied to mixer part of tuner 2 and a directcurrent voltage from loop filter 55 is to varactor diode 2a of tuner 2 to amplify selectively the high frequency. When the tuner does not get tuned, control circuit 7 increases dividing ratio (n) after the set time of delay circuit 10 and sends a new dividing ratio to counter 52, thereby continuing the same  processes.
