Title: Electrophotographic device
Inventor: SATO KAZUNOBU
IPC: G03G15/02
Filed: 1984-10-29
Abstract: PURPOSE:To obtain photographic images of high quality with a certain density by controlling an electrifying voltage to a photosensitive surface in an electrifying part in accordance with the reduction of sensitivity due to the elapse of time after the operation start of a photosensitive body. CONSTITUTION:Just after the operation start, the output voltage of a high voltage generating circuit 33 is low because the terminal voltage of a capacitor 38 of an integrating circuit 39 is low. As the result, the value of the electrifying voltage applied to the photosensitive surface of a photosensitive drum 1 from a charging charger 3 is low. This electrifying voltage rises along a rise characteristic curve determined by the time constant of the integrating circuit 39 in accordance with the elapse of time after the operation start time. This rise characteristic curve is set so as to correspond to a reduction characteristic curve of the sensitivity of the photosensitive surface of the photosensitive drum 2. As the result, the density of character images formed by a laser beam generating device 5 is always held in a certain level, and photographic images of high quality in the certain density level are always obtained just after the operation start as well as a certain time after the operation start.

IPC: H01L41/22
Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To prevent an oscillation characteristics from deteriorating due to a change with the lapse of time. SOLUTION: In this method, production of a crystal oscillator where silver electrodes are formed on both sides of a crystal plate is performed. In this case, silver is vapor deposited on the crystal plate in a vacuum chamber 14, a silver electrode 12 is formed, and an insulated film 13 such as an oxidized silicon or the like is stacked on the silver electrode 12. In a process of accumulating an insulation film 13' on the other side (or a process of eliminating the insulation film 13' accumulated thick by a dry etching), the frequency of the crystal oscillator 25 is measured continuously and frequency adjustment is performed by stopping the accumulation (or an elimination) at a time when the measured frequency matches the set frequency.  Since both the sides of the silver electrodes 12 and 12' are protected by the insulation films 13 and 13', the change with the laps of time in weight of the silver electrodes 12 and 12' is extremely small and it is possible to prevent the deterioration of oscillation characteristic.

Abstract: PURPOSE:To omit a notch of a vibrationproofing material to be secured for a connection area of a conductive pattern by fitting the vibration proofing material to the end part of a vibration transmitting plate and forming a conductive member on the surface of the vibrationproof material in case of detecting the coordinates of an oscillation pen from a vibration transmitting time. CONSTITUTION:A vibrationproofing material 7' is thermally pressed against the end part of the vibration transmitting plate 8. When a conductive pattern 82 formed on the rear face of the plate 8 is opposed to a pattern of a conductive thermal deposition layer 72 and pressed against each other, both the patterns are connected to each other and the pattern 82 is led out through the layer 72. The vibrationproofing material 7' is formed longer than a vibrationproofing material 7 and both the materials 7,7' are pressed against the plate 8 so as to be aligned on the front and rear faces of the plate 8. When the length of the material 7 is just ended at the end part of the plate 8, the material 7' is protraded from the end edge of the plate 8. When the layer 72 exposed to the extruded part is thermally pressed against a conductive pattern on the end part of a flexible printed substrate 14, the circuit on the substrate 14 is connected to the pattern 82 of the plate 8 through the layer 72, so that it is unnecessary to notch the vibrationproofing material.

Title: Plunger-type electromagnet iron core
Inventor: KAMITSUBARA TSUNEO
IPC: F16K31/06
Filed: 1988-09-12
Abstract: PURPOSE:To increase sensitivity of an electric magnet by forming the surface of a magnetic pole in the terraced shape on a plunger side by piling up the plural number of cone trapezoids on the same axis as the plunger and on a fixed iron core side in the shape having a recessed section with many stages which fit in the plunger with a little space in between. CONSTITUTION:The surface of a magnetic pole where a fixed iron core 2a and a plunger 3a are attracted and separated is formed by piling up two cone trapezoids, whose height p equals to a moving distance q of the plunger 3a and which have different diameters, on the side of the plunger 3a and by making a two-staged recessed section which fits in the plunger 3a with a little space in between on the side of the fixed iron core 2a. When the fixed iron core 2a and the plunger 3a are engaged with each other, the movement of the plunger 3a is smooth since there is a little space between the slanted side of the cone trapezoids and the recessed section of the fixed iron core 2a. By this method, the suction force against the same input is increased and a higher sensitivity is achieved.

Title: Bell tone generating device
Inventor: NAKAKAWARA KYOICHI
IPC: H04M3/02
Filed: 1986-09-25
Abstract: PURPOSE:To reduce the size and cost of a bell tone generating device by placing a power amplifier in an intermittent operation state when it is overloaded and thus reducing the mean power consumption. CONSTITUTION:If the power amplifier is overloaded owing to the short-circuiting of an output terminal 4, the input signal (ringer signal output) of a detector 51 decreases in amplitude and its detection output B becomes smaller than a threshold value, so that the output signal C of a decision circuit 52 becomes 0. Then, a counter 53 enters a counting operation state while its output signal D becomes 0, and the counter 53 repeates this operation while the output signal C of the decision circuit 52 is 0. consequently, signals D of 0 and 1 are inputted to a gate circuit 5 alternately and the ringer signal is inputted intermittently to the power amplifier 2, whose mean power consumption is reduced.

Title: Cylindrical armature and its manufacture
Inventor: TERACHI SHIYOUNAI
IPC: H02K15/04
Filed: 1995-08-11
Abstract: PROBLEM TO BE SOLVED: To reduce the reluctance of a magnetic circuit by suppressing the eddy currents so that magnetic fluxes can be concentrated to the winding section of an armature by plating the surfaces, which are not faced to magnets, of the windings of the armature constituting a rotor with a soft magnetic material. SOLUTION: Only necessary parts of the surfaces of windings formed in a flat belt-like shape are plated with a soft magnetic material, such as permalloy, amorphous, ferrite, cobalt phosphorus, etc., by dipping the windings in a plating bath after a plating preventing seal is stuck to the nonplated surfaces of the windings. The plated windings L1 -L6 are flattened in the shearing direction so that overlapping two-layer parts can be formed at the center of the section X, but the windings L1 -L6 become single layers at the hexagonal parts X1 ' and X2 ' at both ends. A cylindrical armature 21 is obtained by rounding the windings L1 -L6 so that the singlelayer sections X1 ' and X2 ' can just overlap upon another and sticking the sections X1 ' and X2 ' to each other.  A more efficient armature can be constituted when a large number of fine cracks are formed in the plated parts at the time rounding the windings L1 -L6 to the cylindrical shape.

Title: Chopper apparatus
Inventor: MATSUURA TOSHIAKI
IPC: H02M3/155
Filed: 1988-09-09
Abstract: PURPOSE:To suppress the rise of an output voltage at the time of a light load by increasing the OFF-period of a chopper switching element relative to the ON-period thereof. CONSTITUTION:At the time of a light load, when an output voltage cannot be controlled even if the conduction ratio of a chopper switching element 5 is set at the minimum value alphamin, said state is detected by a loaded-state detecting means 13 on the basis of said output voltage or output current. A switching period T is changed to 2T to lower a chopper frequency so that a control means 14 having received the detected signal increases the OFF-period of said chopper switching element 5 relative to the ON-period thereof. Thus, when the OFF-period of said switching element 5 increases relative to the ON- period thereof, the discharge time of a filter capacitor 8 becomes longer and an output voltage VP2 is consequently prevented from rising to resemble closely an output voltage Vr to be controlled. Therefore, a dummy load becomes useless and the efficiency of an apparatus is improved.

Title: Power tap changer
Inventor: NAMIKI TAKASHI
IPC: H01F29/02
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To safely, quickly and easily change the tap even in the active state by tightly mounting continuity nuts on bolts of tap changing terminals through an insulation plate until conductive members of the nuts strike against a conductive plate to bring the bolts of the tap changing terminals into a continuity with the conductive plate. SOLUTION: A continuity nut 14 is inserted into a window hole 31 of any tap changing terminal e.g. 102 of an insulator cover 30 and its cap nut (conductive member) is tightly mounted on a bolt 16 of the terminal 102. The outside hexagonal part of an insulation grip 25 is held by spanner to rotate the nut 14 to tighten a conductive plate 13 until the lower end face of the cap part 15b of the nut strikes against the surface of the plate 13 to thereby safely bring the bold 16 into a continuity with the plate 13 through the cap nut. Thus a prim. coil circuit is formed between the tap of the prim. coil connected to a terminal 18 and variable terminal of the conductive plate 13.
