Title: Base material for coating with poultice agent and production thereof
Inventor: TSUCHIYA HIROTAKA
IPC: A61F13/02
Filed: 1989-06-22
Abstract: PURPOSE:To obtain a base material having proper moisture permeability and having flexibility and excellent stretchability by applying a polyurethane emulsion to a fiber base material and drying the same to provide a porous polyurethane layer on the surface of the fiber base material. CONSTITUTION:A porous polyurethane layer 1 is formed by applying a water in oil type polyurethane emulsion consisting of hydrophobic polyurethane, hydrophilic polyurethane, water and an org. solvent to a fiber base material 2 and drying the same. The hydrophobic polyurethane is obtained by reacting hydrophobic polyol, org. diisocyanate and a chain extender and the hydrophilic polyurethane is obtained by using polyethylene glycol at the time of reaction and containing a polyoxyethylene group in polyurethane in an amount of about 20-40% by wt. of the total amount of a polymer. The moisture permeability of the base material for the coating with a poultice agent can be variously changed by charging the composition or coating amount of the polyurethane emulsion. Therefore, by regulating this moisture permeability, a material having proper moisture permeability is obtained and, further, one having flexibility and excellent stretchability is obtained.

Title: Driving circuit for laser diode
Inventor: HANANO NAOMASA
IPC: H04B10/40
Filed: 1981-10-08
Abstract: PURPOSE:To adjust a driving current for a laser diode easily by separating a high-frequency and a low-frequency driving part centering on the laser diode. CONSTITUTION:A laser diode 11 is connected in series to a transistor (TR) 13 for modulation driven by a low-frequency modulated signal SB. To the connection point C between the diode 11 and TR13, a TR15 for high frequency superposition for deterioration in coherency and a high-frequency driving part (current switch 31) are connected. Consequently, the adjustment of the high-frequency driving part 31 is separated from the adjustment of the low-frequency driving part 13 electrically, and one adjustment never exterts influence upon the other, so a driving current for the laser diode is adjusted easily.

Title: Image forming method
Inventor: NAKAMURA TOSHIHARU
IPC: G03G15/05
Filed: 1987-06-29
Abstract: PURPOSE:To easily obtain a high quality image excellent in sharpness of image by forming a developer applying layer which is applied on a non-magnetic sleeve only with non-magnetic photoconductive toner not including magnetic grains, and eliminating relative motion between the photoconductive toner and the non-magnetic sleeve. CONSTITUTION:A magnetic field does not exist in an area from a developer specifying member 6 to a transfer part and the photoconductive toner 5 is non-magnetic. Moreover, the developer applying layer which is applied on the non-magnetic sleeve 1 consists only of the non-magnetic photoconductive toner 5 not including the magnetic grains 4. Then, a self rotating motion does not occur in the movement of the photoconductive toner 5 following the rotation of the non-magnetic sleeve 1 and the relative motion does not occur between the photoconductive toner 5 and the non-magnetic sleeve 1. Thus, the photoconductive toner 5 can be shifted to a transfer part as it maintains the resolution in an optical image irradiation part and the transfer on a transfer sheet 7 is made possible without lowering the sharpness of image.

Title: Interruption controlling system
Inventor: KOYABU MASAO
IPC: G06F9/46
Filed: 1980-11-13
Abstract: PURPOSE:To prevent the unnecessary discontinuance of the microprogram processing, by inhibiting the acceptance of succeeding interruption requests when full latches are enqueued for the access in case of the execution of data transfer between a main storage device and a front end. CONSTITUTION:In the data processing system for data transfer between a main storage device and front ends, when full latches 9-0-9-2 indicating storage conditions of memory access information are enqueued for the access to the main storage device, the lower director does not accept interruption requests from lower front ends even if they occur. As long as the preceding accepted interruption request of the director is stored in memory access buffer registers 8-0- 8-2, succeeding interruption requests of data transfer from front ends are inhibited. Consequently, the microprogram processing of the director is executed without unnecessary discontinuance.

Title: Switching means having self-hold function and self-extinction function
Inventor: SUZUKI TOSHIYASU
IPC: H02M1/08
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To avoid turning-off from slowing down and to decrease the ON voltage even when a switching current is attenuated from a large current and extinct naturally. SOLUTION: Sources of an NMOS 2 and a PMOS 3 are connected, a diode 4 is connected from the source of the PMOS 3 to its gate in this polarity, a resistor 8 and a DC power supply 1 are connected in series from a drain of the PMOS 3 to the gate of the NMOS 2 and a resistor 6 is connected between the gate and the source of the NMOS 2. Thus, when the NMOS 2 is conductive, the PMOS 3 detects a voltage drop across the diode 4 through which a drain current of the NMOS 2 flows so as to detect whether or not the drain current is higher than a prescribed value (holding current), and when higher, the DC power supply 1 drives the NMOS 2 to be conductive via the PMOS 3 and the resistor 8, and when smaller, the NMOS 2 is nonconductive by the resistor 6, then turning-off does not slow down and the ON-voltage is reduced.
