Title: Device for measuring length of weft in liquid jet type loom
Inventor: ODA SHINGO
IPC: G01B21/06
Filed: 1982-05-31
Abstract: PURPOSE:To improve a winding state and to increase the range for changing a storage amt. by constituting a guide part which guides the weft drawn out from a weft bobbin to the position where the weft is wound around a storage drum in such a way that said part is movable in the axial line direction of the storage drum. CONSTITUTION:A guide member having a guide part 60a which guides the weft drawn out from a weft bobbin to the position where it is wound around a storage drum 38 is mounted to a yarn winding bobbin 37 so that the guide part 60a is made movable in the axial line direction of the drum 38. Therefore, the weft can be wound in an exact state on the drum 38 with the guide part 60a in the stage of changing the measuring amt. of length by changing the positions where weft engaging pins 50, 51 move in and out along the axial line of the drum 38 and in the stage of increasing the moving range of an adjustment rod 55 by making the angle between the bobbin 37 and the revolving shaft 18 thereof variable. The winding state is thus improved and the range for changing the storage amt. is increased.

Title: Vertical roots blower
Inventor: OONISHI YOSHIHIRO
IPC: F04C18/18
Filed: 1978-07-28
Abstract: PURPOSE: To permit reduction of the diameter of the bearing of the vertical Roots blower and the size thereof by arranging such as to permit at least either intake or discharge pressure to be partly to the upper or lower side of a rotor so as to provide an upward thrust load opposing the rotor load.  
     CONSTITUTION: In operation, air withdrawn from an intake port is caused by blades of rotors 9 and 10 to proceed along the inner wall of a rotor chamber R to each a discharge port 7. At this time, the pressure on the discharge side is led through a communication duct 20 to annular ducts 18 and 19 and thence to the entire area of oval recesses 21 and 22 provided on the lower side of the rotor 9 and 10, thus raising the rotors 9 and 10. Thus, by determining the area of the oval recesses 21 and 22 acted upon by the normal discharge pressure in such a manner as to correspond to the total weight of the rotors 9 and 10 include of timing gears 14 and 15, it is possible to maintain a substantially balanced state of axial thrust loads, thus permitting a small size and compact blower.

Title: Device for calculating space sum of products
Inventor: KURAKAKE MITSUO
IPC: G06F17/10
Filed: 1985-04-30
Abstract: PURPOSE:To offer an economical and multifunctional space sum of products calculating device by applying N-pieces of picture element data stored at continuous positions and load coefficient selecting information generated according to a function selecting instruction to a multiplier composed of a RAM. CONSTITUTION:The picture element data stored in a frame memory 1 is sequentially read out, transmitted to registers 2-1-2-3, decided according to the function selecting instruction of a microprocessor 10, and synthesized by applying to multiplexers 4-1-4-3 together with the load coefficient selecting information stored in registers 3-1-3-3. The synthesized signal turns out an address signal in the RAMs 5-1-5-3. However, since the multiplied result of the selected load coefficient and the picture data is stored at the address in the RAM, the RAM output becomes the multiplied result as it is, cumulated in the adder 6, a shift register 7 and a gate 8, and stored in a frame memory 9.

Title: Air quantity controller
Inventor: TAKADA SHINJI
IPC: F23N3/08
Filed: 1983-05-24
Abstract: PURPOSE:To suppress air quantity variation to a small value when power source is switched from V-power source to C-power source due to the fault of the V- power source by making it possible to select the opening degree of a damper at a time when the operation is carried out using the V-power source responsive to the load. CONSTITUTION:When V-power source 5 is in fault, and switches 2-4 are changed over to ''open'', ''open'' and ''close'' to start the operation using C-power source, the opening degree of the damper 9 varies toward a damper opening degree 14x. The difference 17x-14x between damper opening degrees is a function of the load air quantity x%, and the time required for the variation is also a function of x%. On the other hand, the time required for increasing from the V-power source operation rotational speed nx to the C-power source operation rotational speed ns is a function of the load x% because ns is fixed to 50Hz or 60Hz. The output curve is selected by a function generator 15 in conformance with the rotational speed varying time. As a result, even when the V-power source is in fault, and changeover to the C-power source is carried out, the increase in the rotational speed and the throttling of the damper are carried out at times substantially coincident with each other.

Title: Toner for developing electrostatic charge image
Inventor: TAKAGI SEIICHI
IPC: G03G9/087
Filed: 1983-05-26
Abstract: PURPOSE:To improve the sharpness of an image by using styrenes and acrylic acid esters or methacrylic acid esters as essential resin components. CONSTITUTION:The number average grain size of a toner of which Wadell practical spheroidicity psiW is 9.95-1.00 is 5-25mum. Such toner has the crosslinking structure of 0.05-90wt% gel content and contains 60-95pts. styrene and 5-40pts.wt. acrylic acid ester or methacrylic acid ester as essential resin components. if the Wadell practical spheroidicity is <=0.95, the spheroidicity is equal to shapeless, thus resulting in nonuniform frictional electrostatic charging and deteriorated fluidity. If the number average grain size is <=5mum, the fluidity is poor, thus having an easy tendency to a photographic fog and deteriorated developability. If said size is >=25mum, the square reproducibility of the fine lines of the image is deteriorated. When the gel content or styrene exceeds the above- mentioned range, the elevation of a fixing temp., etc. arise. The sharpness of the image is improved by using the toner compounded in the above-mentioned way.
