Title: Electrophotographic photoreceptor
Inventor: SUZUKI SHINICHI
IPC: G03G5/06
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To obtain an electrophotographic photoreceptor excellent in mechanical properties and having enhanced chemical durability and light resistance without impairing photosensitive characteristics such as electrification ability and sensitivity, coatability, etc., by incorporating a wax having an ester group into the outermost layer of a photosensitive layer and using a compound having a hydrazone skeleton as an electric charge transferring agent. SOLUTION: This electrophotographic photoreceptor has a photosensitive layer on the electrically conductive substrate and the outermost layer of the photosensitive layer contains a wax having an ester group. In order to improve electrical characteristics such as residual potential and sensitivity, the content of each of inorganic elements present as impurities in the wax is preferably reduced to <=20 ppm. When a surface layer is formed, the wax is dissolved in a coating fluid for the surface layer and the coating fluid is applied to form the objective photoreceptor. A compound having a hydrazone skeleton used in the photosensitive layer is not particularly limited if it is a compound which functions as an electric charge transferring agent.

Title: Input circuit
Inventor: OBATA HIROYUKI
IPC: H03K19/20
Filed: 1983-03-14
Abstract: PURPOSE:To obtain stably an output corresponding to each logicall state by connecting each input of plural logical circuits having a different logical threshold value to one input terminal so as to input >=3 of logical states. CONSTITUTION:Each input of plural logical circuits 11, 12 having a different logical threshold value is connected to an input terminal IN. Then, each output of the plural logical circuits 11, 12 is connected to output terminals OUT I and OUTII. Then, the logical state corresponding to an input voltage applied to the input terminal IN is obtained by the number being the number of logical circuits added by 1. Since >=3 of logical states are inputted from one input terminal in this way, the number of input terminals of an integrated circuit is reduced.

Title: Dc brushless motor
Inventor: FUJIMAKI TADAO
IPC: H02K29/00
Filed: 1984-03-05
Abstract: PURPOSE:To readily and accurately position poles by combining a plurality of sets of stator units made of stator core and stator coils. CONSTITUTION:Stator coils 2, 3 are respectively mounted on the poles 4, 5 of a laminated core 6 which has a pair of opposed poles 4, 5, connected in series so that the polarities of a magnetic field due to currents flowed to the coils 2, 3 become the same, thereby constructing a stator unit. When two stator units A, B which are made of a stator core 6 and stator coils 2, 3 are inserted fixedly in a case so that the central axes of the poles are different at 90 deg. from each other, a 2-phase stator is composed. Thus, since a polyphase stator coil can be readily composed merely by combining a plurality of the same stator units associated in advance, the poles can be readily positioned.

Title: Plate type display device
Inventor: NONOMURA KINZOU
IPC: H01J31/12
Filed: 1984-03-07
Abstract: PURPOSE:To reduce generation of scattered electrons and the secondary electrons by forming the electron beam passage-holes of an electron beam taking- out means so as to be magnified from an entrance toward an outlet. CONSTITUTION:Electron beam passage holes 26 and 27 are so formed that the holes may be magnified from an entrance toward an outlet respectively. Thereby, an electron beam passing through the electron beam passage holes 26 and 27 rarely collide with the respective inner walls and the edge parts near the outlets of the electron beam passage holes 26 and 27. Accordingly, generation of scattered electrons and the secondary electrons can be remarkably suppressed so as to perform clear display.

Title: Controller for leveler
Inventor: SATOU TADAO
IPC: B21D7/02
Filed: 1981-03-23
Abstract: PURPOSE:To minimize the quantity of looping of a coil material by providing circuits which perform feedback controlling of the operating speed of a leveler in accordance with the speed commands corresponding to the operating speed of a variable speed press and correct the speed commands during transient operation. CONSTITUTION:An average line speed is operated from the press speed signal outputted from a speed power generator 5 of a variable speed press 4 and the output signal of a feed pitch setting switch 6, and the speed signal according to this is supplied to a control board 8. The leveler speed signal from the speed generator 11 is fed back to a control board 8, so that a leveler 1 is operated at the average line speed. When the quantity of looping decreases at the start of the line and the response delay of an electric motor 9 is caused, a correction signal is outputted from a correction quantity setting switch 15 by the speed increase command from the 1st comparator 12, whereby the quantity of looping is returned to the original state. At the stopping of the line, the output deviation between the difference between the leveler speed and the speed command and the set value from a comparator 13 are supplied to a winding 19 of a brake, whereby the increase in the quantity of looping is prevented.

Title: Character pattern registering device for printer
Inventor: SAITO SAYO
IPC: B41J2/485
Filed: 1992-01-31
Abstract: PURPOSE:To register character pattern easily by a printer independently without requiring complicated programming from a host device when the character pattern is to be registered in the printer. CONSTITUTION:An operation section 101 sends a registration code of a character pattern and information of the character pattern to be made by pressing down a switch of an operation panel to a display section 102 and a controller 103. The display section 2 displays on a liquid crystal display console at the same time that they are made. The information decoded at the controller 103 is stored in a registration buffer 104. Thus, registration by complicated programming from a host device is eliminated.

Title: Image forming device
Inventor: IWASAKI SHINICHI
IPC: G03G15/00
Filed: 1985-03-04
Abstract: PURPOSE:To stack and store speedily sheet materials after image formation almost at a specific position on a tray by providing an air suction port to a flank of an image forming device body below a discharging means and above a fitting part for the tray. CONSTITUTION:When a sheet material S after image formation is discharged from the discharging means 15, an air layer 22 is formed between the sheet material S and tray 16 or a sheet material S which is already stacked on the tray 16. A discharge fan 20, however, operates in synchronism with the discharging operation of the discharging means 15 to suck the air forming the air layer 22 through an air intake 17 and discharge it to the outside, so the air layer 22 is eliminated. Consequently, the sheet material S discharged from the discharging means 15 is stacked and stored almost at the specific position on the tray 16 speedily without any harmful delay operation due to the cushion operation of the air layer 22, conveying operation perpendicular to the discharge direction of the sheet material S, etc.

Abstract: PURPOSE:To feed a linear signal to an input current by providing a concentric groove on the end face of a plunger. CONSTITUTION:A concentric groove is provided at the section A on the end face of a plunger 5. Thereby, the magnetic flux passage cross section area of the plunger main body is reduced, the magnetic flux is saturated at this portion at a high input current to generate the magnetic resistance, and finally the suction force can be reduced. At a low input current, the magnetic flux is not saturated and does not affect the suction force. As a result, the stable signal pressure with linearity can be fed to each input current.
