Title: Automatic dimming electronic flash device
Inventor: HORINISHI KATSUMI
IPC: G03B15/05
Filed: 1979-09-04
Abstract: PURPOSE:To surely prevent malfunctions such as commutation failure and make possible continuous emission operation of a super high speed by forming the charging circuit of a commutation capacitor after the start of emission operation by using a switching element of an extremely small resistance component. CONSTITUTION:When a flash start signal is supplied to a terminal 11, a trigger 10 operates and the signal is supplied to an auxiliary switching element 13 and a delay circuit 12, then the element 13 conducts to rise the potential of the connection point (a). The potential fluctuating component of the point (a) is then differentiated 14 and is applied to a gate 5' of a main switching element 5, so that the element 5 conducts. This causes electric current to flow in the element 13, commutation capacitor 6 and element 5 and causes the capacitor 6 to be charged and this completes the preparation for emission of a flash discharge tube 4. In addition, the discharge tube 4 is triggered by the output of the delay circuit 12, whereby emission is accomplished. In this way, the capacitor 6 is rapidly charged via the switching element and this makes possible the continuous emission of a super high speed.

Title: Method of correcting overlapped period of commutation of high frequency link dc/ac converter
Inventor: UEMATSU TAKESHI
IPC: H02M7/5387
Filed: 1995-04-14
Abstract: PURPOSE: To improve the output voltage waveform from a cyclone converter part and reduce the distortion of waveform in the vicinity of zero cross by hastening the ON-OFF control of the bidirectional switching element of a cyclone converter part by the commutation overlapped period. CONSTITUTION: Since a switching element Su of U phase performs switching in the period while the output voltage is generated, the output voltage of the cyclone converter is delayed by the commutation overlapped period of the commutaion of power source. As a result, for the waveform of the output voltage of the cyclone converter part, the waveform in the vicinity of zero cross is distorted, and it becomes one which includes low-order higher harmonic components. Accordingly, the switching operation of the switching element Su is advanced by the commutation overlapped period. As a result, for the waveform of the output voltage of the cyclone converter part, the distortion of waveform decreases in the vicinity of zero cross, and the low-order harmonic components are suppressed.

At this time the product part is not pressed and therefore no distortion occurs. When the thickness in the axial direction of the cross gate part is large, deflection becomes hard and therefore provision of a notch part in the bottom is recommended.

IPC: G03G21/00
Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device that can stably obtain a fixed image in a good image state by correcting the image forming conditions. SOLUTION: In this device, when a test image for fixing is formed on a recording body (S1), a required toner fixing quantity is calculated by a central control part from test image data acquired at S3 (S4). Furthermore, when the intensity Ib of mirror reflection light from the testing image for fixing and light emitting intensity Ia of a halogen lamp are detected by an image information detection part, the glossiness of the test image for fixing is calculated utilizing these data (S5). Next, the actual quantity of fixed toner that is fixed to the recording body is estimated on the basis of the surface temperature (fixing temperature) of a heating roll detected by a temperature sensor at S2 and the glossiness calculated S5 (S6). Then, the forming condition of an unfixed image is compensated on the basis of the required toner fixing quantity and the actual quantity of fixed toner so that an appropriate quantity of the toner is fixed to the recording body (S7). Thus, a fixed image with a good image state can be stably obtained since fixing is carried out in a state where an appropriate quantity of toner is fixed on the recording body.
