Title: Discharge lamp lighting apparatus
Inventor: KOBAYASHI MASAYUKI
IPC: H05B41/24
Filed: 1990-02-28
Abstract: PURPOSE:To carry out preheating sufficiently and prevent early blackening in the periphery of an electrode and short-circuiting of electrodes by setting a preheating time on a timer circuit and applying direct current to a current transformer for a set period after electricity application. CONSTITUTION:A timer circuit 150 is so composed as to be turned off after a set time passes since an a.c. power source 110 is turned on. After the a.c. power source 110 is turned on, voltage generated on the secondary coiled wire 130b of a current transformer 130 becomes over Zener voltage of a voltage- constant diode 156 and thus a transistor(Tr) 160 is turned on. Then, a switching Tr 126 is quickly turned off. Due to this, oscillation frequency becomes high and voltage of a starting capacitor 132 is lowered and the electrodes 118a and 118b are sufficiently heated without a fluorescent lamp 118 being turned on. When a switch 154 is turned off by the circuit 150 and the preheating circuit 152 is shut after a set time passes, oscillation frequency of the Tr 126 becomes low and the voltage of the capacitor 132 rises and thus the fluorescent lamp 18 starts discharging. In this way, early blackening in the periphery of electrodes and short-circuiting of electrodes are prevented.

Abstract: PURPOSE:To prevent toner from flowing out from a toner container by oscillation or shock from traveling, etc., of a developing unit by slanting a toner feeding opening side part, which feeds toner to a developing unit from the toner container, to the upper direction in the toner feeding direction. CONSTITUTION:A multiple number of developing units 24 are mounted on a traveling device freely movable toward a developing part position with a photosensitive body drum, and a multiple number of toner containers 35 responding to each developing unit 24 are immobably placed in the upper direction of the developing unit 24. When the developing unit 24 is traveled, a connecting pipe 43 and a receiving pipe 42 of a toner replenishing path 36 have their position changed in the traveling direction of the developing unit 24 having the engaging length changed. Therefore, the replenishing path 36 can follow the traveling of the developing unit 24. Because the feeding opening side part of the toner container 35 of the replenishing path 36 is slanted in the upper direction, in the toner feeding direction, toner replenishing can be carried out without having the toner flow out to the developing unit 24 from the toner container 35 due to oscillation or shock.

Title: Ultrasonic motor
Inventor: ITOU MOTOAKI
IPC: H02N2/00
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To properly control the rotation of a rotor and prevent the deterioration in the pressure-welded faces of both elastic bodies for improved durability. SOLUTION: An annular projected portion 5p of an elastic body 5e and the face 6r opposite to the annular projected portion 6p of an elastic body 6e face opposite and pressure-welded to each other to narrow the pressure-welded faces, and furthermore both the elastic bodies 5e, 6e are formed into one and the same shape to match the numbers of natural oscillations of a stator 5 and a rotor 6 with each other. When piezoelectric vibrators 5v, 6v are supplied with a signal of the resonance frequency of the stator 5 and rotor 6, normal traveling waves can be produced on the pressure-welded faces and the traveling waves can be matched with each other. The rotation of the rotor 6 can be properly controlled by continuously shifting the engaging lock position of the traveling waves.  Since an inner circumferential edge 5pi of a projected face 5pp is positioned outside the inner circumferential edge 6ri of the opposite face 6r, and the outer circumferential edge 5po of the projected face 5pp is positioned inside the outer circumferential edge 6ro of the opposed face 6r, the inner and outer circumferential edges of not cross each other during the rotation of the rotor 6. For the reason, the inner and outer circumferential edges are prevented from rubbing each other, and the pressure- welded faces are prevented from being deteriorated, and the area of pressure-welding can be made constant.

Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To know a vibration proof state as necessary and to improve operability therefor by making a display indicating that the correction of a shake is in execution, in response to the operation of an operating member at the time of correcting the shake, with a display means. SOLUTION: A photographer switches a vibration proof operating switch (vibration proof switching member) 912 to the position of 'vibrationproofing ON and display ON'. When the photographer targets an object and half depresses a release button (release operating member) 911, photometry, range- finding and lens focusing drive are attained, a correcting means 910 becomes a controlled state and the restraining of the correcting means 910 is released. After a delay of a specified time, the correction of the shake is started. In such a case, when the shake is properly corrected, a sounding body issues a sound, so that the photographer perceives the fact.  After that, only when the photographer temporarily releases his or her finger from the release button and half depresses it again, even is he or she does not know whether vibrationproofing is in execution or not, because he or she targets the object for a short while, immediately the sound for the ON state of the correction of the shake is issued to inform the photographer of the face.

Abstract: PURPOSE:To enable an S/N of a detection defect signal to be improved and detection accuracy of the defect to be improved by controlling a distance between magnetic poles and that from the magnetic poles to a thin steel band to a constant relationship and increasing a magnetic efficiency for the thin steel band. CONSTITUTION:When a distance between magnetic poles 4a and 4b (magnetic gap spacing) W of a magnetic equipment 4 within a hollow roll 1a is controlled to be 2L<=W<=8L for a distance L between the magnetic poles 4a and 4b and a thin steel band 10, a relative output becomes approximately 70% or higher and a magnetic density of a magnetic flux passing through the thin steel band 10 becomes higher, thus resulting in a level for fully withstanding a practical application. Also, by forming a thickness of the roll 1a to be thick at both edge parts where rolling axes 3a and 3b are mounted and thin at a central part which contacts the thin steel band 10, reduction in strength of the roll 1a can be compensated for to some extent and at the same time a lift-off d between a magnetic sensor 7 and the thin steel band 10 can be set shorter, thus obtaining a stable magnetic flux and enabling detection sensitivity to be improved.
