IPC: G03G15/08
Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To reduce fog on an image background due to the oversupply of toner by providing a platelike member above a supply roller, and forming a toner-flow boosting space between the supply roller and platelike member. SOLUTION: Above the supply roller 12 the platelike member 20 is provided, and the toner-flow boosting space 25 is formed between the supply roller 12 and the platelike member 20. This platelike member 20 is made of a metallic material and so disposed in the toner storage part 16 of a main body case 15 as to extend above the supply roller 12 and along its axis. This reduces a proportion of the weight of toner which directly falls onto the supply roller 12 from above, making it easy for the toner T to move in the toner-flow boosting space 25 between the supply roller 12 and platelike member 20. Therefore, the toner flow accompanying the rotation of the supply roller 12 is made active, and the fog on the image background due to the oversupply of the toner can be reduced.

Title: Paper connecting device and sizing position detecting method therefor
Inventor: OSAWA SHIN
IPC: B65H37/04
Filed: 1990-10-05
Abstract: PURPOSE:To make a distance constant between shaft centers of a gear at all times and give a precise rotating speed to a new winding paper by mounting the gear on a turning shaft and a turret arm. CONSTITUTION:The rotation of a motor 10 is transmitted to a driving member 18 supported concentrically by a turning shaft and also to the driven member of a winding core support shaft mounted on each turret arm 8 to rotate a new winding paper. A clutch 38 switches the driving force of the motor between transmitting state and transmission stopping state by a clutch selecting device 78 to selectively transmit the rotation only to the winding core support shaft having the new winding paper installed thereto. Thus, at the time of connecting papers, when the winding diameter of the old winding paper reaches pre- diameter, the turning shaft is automatically rotated to change the position of the winding paper, and the motor is driven to accelerate the winding core supporting shaft and the new winding paper supported thereby to a necessary rotating speed, but, in this case, the driving force of the motor is transmitted only to the winding core support shaft requiring acceleration by the operation of the clutch according to the instruction of the clutch selecting device.

Title: Object lens actuator
Inventor: SASAKI YOSHINORI
IPC: G11B7/09
Filed: 1988-10-21
Abstract: PURPOSE:To reduce unnecessary angular moment produced in a lens holder and to obtain excellent tracking operation characteristics by adhering grooved iron plates on permanent magnets pinching a track coil. CONSTITUTION:Iron plates 50 and 51 provided with rectangular grooves are adhered on permanent magnets 3A and 3B of this object lens actuator. By the iron plates 50 and 51 provided with the rectangular groove, the magnetic flux density distribution between the magnets 3A, 3B and center yokes 2A, 2B is reduced in recessed state at the central part. Therefore, even when the center of track coils 4a, 4b and 5a, 5b existing in the magnetic field is deviated from the center of the magnets 3A and 3B, the change in magnetic flux density received at a cross-sectional section is reduced. Then, the moment produced by the electric currents flowing through the track coils is compensated with each other and only the component intersecting orthogonally with the optical axis becomes effective. Therefore, excellent tracking operation characteristics can be obtained.

Title: Loop transmission device capable of specifying failure position
Inventor: OISHI KOJI
IPC: H04L12/423
Filed: 1999-09-21
Abstract: PROBLEM TO BE SOLVED: To securely specify a failure position if a fixed failure or intermittent failure occurs on a transmission line. SOLUTION: In a looped transmission system, each child node always monitor whether a frame received from the upstream side of the transmission line is normal or abnormal, saves failure information in its internal memory if a failure is detected, and integrates how many times the failures occur in its internal memory. A parent node sends a polling frame to the transmission line at constant intervals and collects failure information from all the nodes in the loop if the ratio of the return of the frame to the parent node after one round of the loop decreases to a level below predetermined. An intermittent failure on the transmission line is detected from a decrease in the rate at which the polling frame sent by the parent node does not make one round of the loop to a level below predetermined.  For specifying the failure position, the most upstream node which is detecting the failure is found from the collected failure information of all the child nodes and it is judged that the node is right behind the failure.

Title: Evaluating method for welding strength in fillet welding
Inventor: SUENAGA KATSUTOSHI
IPC: G01N33/20
Filed: 1988-10-21
Abstract: PURPOSE:To evaluate the welding quality by evaluating the depth of penetration by a leg length ratio obtained by dividing the vertical leg length of the depth of penetration with the horizontal leg length. CONSTITUTION:The nearer an aimed position from a base metal 1 to be welded is to the end face of the base metal 1, the deeper the depth of penetration becomes, and a leg length ratio B/A being a ratio of leg length A and leg length B comes near '1'. On the contrary, the farther the aim position is from the end face of the base metal 1, the shallower the depth of penetration becomes, and the leg length ratio comes near '0'. However, when the aimed position comes near excessively the end face of the base metal 1 and becomes a minus aim, the depth of penetration becomes shallow, and the leg length ratio comes near infinity . Accordingly, by measuring the leg length by a leg length gauge, and managing it so that its ratio becomes, for instance, 0.7-1.5, the welding strength can be managed.

Title: Production of metal powder
Inventor: ARIMOTO NOBUHIRO
IPC: B22F9/08
Filed: 1992-10-06
Abstract: PURPOSE:To provide a high-purity fine metal powder. CONSTITUTION:A base material is rotated, supplied downward into a conical high-frequency induction coil with the apex angle theta formed by the generator of the cone controlled to 30-90 deg. and with the apex angle side turned downward, melted by the coil and dropped to form the molten metal, a high-speed gas (e.g. gaseous Ar and N2) is blown against the molten metal which is powdered. When a coil consisting of a conical part and a cylindrical part is used as the coil, the molten metal is effectively insulated from heat, and the finer powder is obtained. A thin molten metal current suitable for gas atomization is dropped to a fixed position in this way. Further, since the metal is kept out of contact with other materials during the whole process starting with the melting of the materials and ending in the solidification of powder, a fine metal powder which has been hardly contaminated is produced.

Title: Manufacture of ferroelectric liquid crystal display element
Inventor: ISHIHARA SHOICHI
IPC: G02F1/13
Filed: 1988-10-24
Abstract: PURPOSE:To vary the liquid crystal orientation control force of an orienting film greatly at the time of manufacturing and actually using the liquid crystal display element by including a process wherein the hydrophibic property of the surface of the orienting film varies by light irradiation. CONSTITUTION:While light irradiates from a mercury lamp nylon-made nonwoven fabric is rubbed against the surfaces of orienting films 3 and 4, and the light irradiation is then stopped temporarily; and the films are stuck together across bead spacers 6 and the periphery except where an injection hole is formed is sealed with sealing resin 5. Then while the light irradiates again, ferroelectric liquid crystal 7 is injected into the element under reduced pressure in a C-phase temperature range of specific temperature. This liquid crystal shifts in the order of an I phase, a Ch phase, an SmA phase, and a chiral SmC phase in a temperature lowering process. Then the element is cooled to room temperature, the light irradiation is stopped, and the injection hole is sealed to form the ferroelectric liquid crystal display element. Consequently, the film which is weak in orientation control force in the actual driving, but increased in the orientation control force is obtained.
