Title: Rotary feeder for lump material
Inventor: ASAI SADAO
IPC: B65G65/48
Filed: 1981-03-11
Abstract: PURPOSE:To cut and feed a lump material continuously by arranging individual rotors so that their pockets are placed at different phases and at least one pocket always faces a feed port and an exhaust port. CONSTITUTION:Since pockets 11, 11 of rotors 2, 3 are placed at different phases so that one of the pockets 11 always faces an exhaust port 6, garbages are continuously cut out by a constant amount. Therefore, a combustion status of an incinerator connected to the exhaust port 6 through a chute, etc., which is not shown in this figure, is stabled, and troubles such as incomplete combustion or pulsating of furnace pressures, etc. do not occur. Furthermore, if foreign objects such as stones or metals, etc., are going to be engaged against circumferences of the rotors 2, 3 when the rotors 2, 3 are conveying the garbages, a  damper 21 rotates to flee upward with an axis 20 as a center, and the foreign  objects are prevented from being bitten.

Abstract: PURPOSE: To efficiently arrest particles contained in a material under the application of a simple structure by providing a fine particle arresting section made of a recess formed around the axis of a flow passage and a vessel body continuous to the recess at a position downstream of a discharge electrode in the flow passage. CONSTITUTION: A forming material de-electrified in truncated cone type space 21 is transferred to a downstream area, together with an air flow.

Title: Manufacture of magnetic recording medium
Inventor: TAKAHASHI TOSHIROU
IPC: H01F41/26
Filed: 1984-02-28
Abstract: PURPOSE:To obtain a magnetic recording medium with high performance while decreasing a magnetic substance deposition processing time and saving power and magnetic ions by applying machine processing after a packing agent is packed for the purpose of surface protection of an anodic oxide film at machine processing at a blank space where no magnetic substance is packed in the pore. CONSTITUTION:Electrodeposition is processed based on the correlation between the deposition time and deposition state of a magnetic substance under the condition of each pore diameter, the processing of deposition is stopped with 20-80% of packing rate of the magnetic substance film, and the process transits to the next machine processing process in this state. Then the blank space having no magnetic substance is left in the pore after the processing of deposition of the magnetic substance and surface damage is caused during the machine processing. Then after the deposition processing of the magnetic substance, a packing agent Fi is packed in the blank space having no magnetic substance M in the pore so as to form nearly the same processing condition of machine processing to the entire film. As the packing agent for the purpose of the surface protection of the anodic oxidation film at machine processing, a resin such as acetal resin dissolving a resin with small friction coefficient in a solvent is used.

Title: Bidirectional optical coupler
Inventor: YAMANE HIROSHI
IPC: H01L31/12
Filed: 1984-02-27
Abstract: PURPOSE:To transmit and receive signals by two signal lines on one side by simple constitution by providing a bias power supply at an output step in a photoreceptor with a switching means and connecting a light-emittor and the photoreceptor in parallel at all times. CONSTITUTION:When an input signal to drivers 7, 7 is at L, a bias is applied to a transistor 14 for a first photoreceptor. Consequently, when signals are transmitted over signal lines 8, 8, a first light-emitter 11 emits light because a transistor 24 for a second photoreceptor is positioned in an OFF region, and the first photoreceptor receives and processes the light and reception signals are obtained in signal lines 9, 9. A second light-emitter 21 functions as load for the transistor 14 at that time, but bias currents do not exceed a dark current region in the second photoreceptor when they are small. When the input signal to the drivers 7, 7 is at H, on the other hand, a second optical coupler 20 inversely functions, and signals can be transmitted over the signal lines 8, 8' on the left side from the signal lines 9. 9' on the right side. Such a bidirectional optical coupler has a strong resistance to noises, etc., and can be adapted in a device having a small number of signal lines.

Title: Arc coordinate conversion device
Inventor: KUSUMOTO KAZUHIDE
IPC: G01S7/14
Filed: 1992-01-29
Abstract: PURPOSE:To eliminate the time for unnecessary processing and to remove the limitation of the display capacity of a random scan type display device by selecting one of two correction angles, selected according to a comparison result, with an arc end signal. CONSTITUTION:The X coordinate (i) and Y coordinate (j) of the center of correction are sent to a center distance calculator 15, which calculates the distance between the center of a display screen and the center coordinates of an arc to be displayed. This center distance is calculated by squaring the X coordinate and Y coordinate of the display screen center and the difference between the X coordinate and Y coordinate of the inputted correction center respectively and extracting the square root of their sum. A subtracter 16 calculates the difference of the calculated center distance from a correction radius outputted by a multiplier 13a and a decision device 17 decides whether or not the value exceeds the radius of the display screen. When the value exceeds the display screen, the effective area of the display arc on the display screen is not crossed, so an outside-distance-range signal (k) a selector 18 is sent out to a selector 18, which once receiving the outside-distance-range signal (d), sets the correction radius (h) to '0'.
