IPC: B65G65/48
Filed: 1981-09-10
Abstract: PURPOSE:To reduce the trouble of the device and facilitate the check and maintenance of an  rocking drive part by a structure wherein the rocking drive part of the arms of the constant  delivery device of particulate material or sticky substance is provided outside a storage tank. CONSTITUTION:The constant delivery device 1 consists in fixing a rotational body 15, to which  a means 14 for raking-up particulate material of the like is supported, to the upper end of a  hollow shaft 10, which pierces the bottom plate 9 of the storage tank and rotates unidirectionally. The means 14 for raking-up has cylinders 17 rotating integrally with the shaft 10 as the  driving part and engaging with a key so as to be rockingly transmissible to a shaft 19 loosely  fitted into the hold of the shaft 10. A rockingly transmitting means 23 is fixed to the upper end  of the shaft 19. Arm shafts 24 are rockably supported to the rotational body 15 and arms 27  are respectively fixed to the lower end of the arm shaft 24 and capable to rock integrally with  a means 26 for being rockingly transmitted. When the delivery device 1 is put into operation,  the cylinders 17 rotate integrally with the shaft 10 so as to change the extrusion of the arms  27 out of the rotational body 15 during their eccentrically rocking motion in response to the  viscosity of the particulate material within the tank, resulting in adusting the load applied to  the device 1 and enabling to continuously deliver the particulate material or the like.

Abstract: PURPOSE: To prevent the occurrence of various kinds of inconveniences by cooperatively moving the automatic dimming light emitting and photo detecting parts in opposite directions so as to make contact to or detach from the optical axis of the camera lens and at the same time controlling the opening and closing of a power source switch.  
     CONSTITUTION: When the knob 5 provided to the mold part 1 of the automatic dimming strobe emitting device is operated at the flash photographing, the automatic dimming light emitting part 2 and photo detecting part 2 in a housed state are cooperatively moved in mutually opposite directions by drive levers 8, 9, causing the light emitting part 2 to detach from the optical axis of the camera lens and the photo detecting part 7 to approach thereto. At the same time, the power source switch 3 is opened and closed according to the movement of the light emitting part 2. Hence, the light emitting part and photo detecting part are housed in the mold part 1 while not in use and this prevents the occurrence of various kinds of inconveniences such as staining of these parts, the unnecessary consumption of power source and red-eye phenomena and others owing to the correct position of the light emitting and photo detecting parts with respect to the optical axis of the lens during use.

Filed: 1984-07-10
Abstract: PURPOSE:To obtain a clear and endurable printing image with little differences in density of the initial and final stages of printing by printing with the use of an ink which has a specifically adjusted viscosity and through a medium of a porous layer of heat-resistant resin. CONSTITUTION:Pertaining to a recording medium which contains a heat fusion type ink in its porous structure and which is good for repeated use, during the forming process of porous layer, the medium is dissolved in two or more solvent groups like water or volatile organic solvents has (have) volatility lower than that of a solvent which easily dissolves the resin of the layer but is almost insoluble in the latter and yet may be used as a solvent for dilution; and evaporated, dried and hardened. Due to the above properties a skin forming on the porous resin layer surface is prevented and a decreased in printing density in the initial stage of printing is prevented. In addition, by controlling a melting velocity of heat fusion ink under 40 cps at 100 deg.C oozing of ink out to the porous layer surface by capillary action is facilitated. By the above regulation of the viscosity of the ink, regardless of repeated printing, printing image of little difference in density becomes obtainable, and an excellent printing durability is brought about.

Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To provide a power feeding system which can suppress the energy loss to a minimum by properly controlling the operating point of an AC genera tor. SOLUTION: Between an AC generator 1 and a load 4, a rectifying section 2 and a DC-DC converter 3 for outputting the stepped-down input DC voltage are installed.
