Title: System for controlling operation of fan handling granular dust
Inventor: MIURA HARUO
IPC: F04B49/10
Filed: 1979-11-16
Abstract: PURPOSE: To reduce the amount of abrasion of an impeller of a fan by a method wherein a density as well as an intensity of collision of granular dusts are sensed to carry out an operation under reducing a number of revolution of the impeller when the impeller is exposed to a condition wherein abrasion thereof is heavy.  
     CONSTITUTION: A sensor 2, provided on a delivery casing of a fan 1, detects an energy wave due to coolision of granular dusts. Subsequently, a density and an intensity of the coolision of the granular dusts are obtained in an operating device 4 by above-described energy wave. The density of the granular dusts is determined by a number of peaks during an optional time period (t) amoung few minutes of an operation time of the fan due to the collision phenomena of the granular dusts thus detected. The density and the intensity of the collision of the granular dusts computed by the above-described manner are memorized into a memory 5 at every few minutes, a decision whether a number of revolution of the fan 1 should be changed or not is decided by a decision circuit 6 and a signal to reduce the number of revolutions of the fan 1 is inputted into a controller 7 when it is judged that abrasion of the fan 1 would become heavy.

Filed: 1980-10-22
Abstract: PURPOSE: To smoothly carry a predetermined amount of a ribbon synchronizedly with typeprinting operation of a printer, by making the drive member of a cassettemounting device, which rotates synchronizedly with typeprinting operation of the printer, couplable to each cassette, respectively.  
     CONSTITUTION: When typeprinting operation is performed, the rotation of a ratchet wheel 4 is transmitted through the first to third gears 5, 13, 14 to the fouth gear 15 to rotate a rotary member 16 by a predetermined rate. At this time, a used carbon ribbon 44 is wound onto a winding reel 49 by the engagement of an engaging needle 18 with the ribbon 33, and a large tension along the winding direcion is concurrently applied to the ribbon 44 exposed outside a cassette 36 by the spring power of a tension spring 33. A ribbon tension-control lever 27 is rotated by the tension, so that the engaging ratchet 34 of a drive lever 32 is detached from a ratchet 24a. Consequently, ratchet wheel 24 and a ribbon-feed reel 46 are integrally rotated to smoothly feed the predetermined amount of the ribbon 44 to the typeprinting surface of a platen under the condition that the tension is constantly applied to the ribbon 44 at every typeprinting operation.

Abstract: PURPOSE:To increase the strength of the shutter blade without decreasing the productivity by cutting a part which becomes an edge part when passing through a shutter opening part and forming a slit, and cutting a part other than the slit formation edge of a base material. CONSTITUTION:The rectangular slit 1a which becomes a slit formation surface when the blade passes through the shutter opening part and punch holes 1b and 1c are formed in a thin plate 1 by a cutting means such as a press. The paint is sprayed on one surface of this thin plate 1 from a spraying device 2 and different paint is sprayed on the other surface from a spraying device 3. Then the plate is positioned with the punch holes 1b and 1c after both the surfaces become dry to some extent, and the thin plate is cut by the cutting means such as the press. Consequently, the production process is simplified and the camera shutter blade having strength can be manufactured without spoiling the mass-productivity.

Filed: 1979-11-16
Abstract: PURPOSE: To provide a compact stretching apparatus with ease of film stretching by individually devising the delivery roll of a film, the take-up roll and the widthwise inducing device.  
     CONSTITUTION: A film is delivered from film delivering rolls 1 and strectched widthwise with a film width stretch inducing device 3 while taken up by film take- up rolls rotating at a high spread whereby the film is biaxially stretched simultaneoulsy. Thus, a film can be obtained with a simple apparatus. The delivery rolls 1 and the take-up rolls herein used are divided into a central delivery roll 11 and a central take-up roll 21 and a lug delivery roll 12 and a lug take-up roll 22 respectively. The inducing device 3 is designed to house and retain the lug of the film while blowing air adjusted in the temperature against the film. This reduces the sliding resistance between the lug of the film and the inducing device thereby facilitating the widthwise stretching of the film.
