Title: Picture image pickup device
Inventor: OTA YOSHITAKA
IPC: H04N5/335
Filed: 1987-04-24
Abstract: PURPOSE:To improve a sensitivity at the time of a field photographing by effectively using the signal of all picture elements even at the time of a field recording by switching the sensitivity of an AE control circuit according to a field recording time and a frame recording time. CONSTITUTION:When a change over switch 3 is set to a field recording mode, a setting signal is transferred to a CPU, the CPU applies a control signal to a transfer pulse generating circuit 2. Consequently, the transfer pulse generating circuit 2 generates a transfer pulse for a field storing mode and applies to a vertical transfer part 1b. The setting signal of the change over switch 3 simultaneously enters a sensitivity switching circuit 4 and the sensitivity switching circuit 4 receives a light from an object and transmits a photometry signal to an AE (automatic exposure) control circuit for controlling a diaphragm so as to execute a proper exposure. The AE control circuit receives the output of the sensitivity switching circuit 4 and adjusts the diaphragm or a shutter speed so as to have an optimum exposure. Thereby, even at the time of the field recording, the picture of the optimum exposure can be obtained.

Title: Voltage converter
Inventor: MUKOGAWA MASASHI
IPC: H02M7/12
Filed: 1995-03-22
Abstract: PURPOSE: To enable the execution of resonant operation regardless of the ripple of input voltage by separating a voltage transformer from a power source, synchronizing with the OFF of a first switching element, by means of a second switching element, and connecting the power side of the voltage transformer to a ground concurrently by means of a third switching element. CONSTITUTION: A first switching element 3 and a second switching element 4 are driven at the same time with set frequency by a control circuit 2, and by the signal from a voltage detection circuit 19, the width of the ON period of the switching elements 3 and 4 is controlled to control the output. The control circuit 2 receives the supply of operation power from an auxiliary winding 24, and also controls the width of the OFF period of the switching elements 3 and 4, synchronizing with the resonance wavelength. Here, while the circuit performs resonant operation, the terminal on power side of the voltage transformer 5 is kept at ground potential by the third switching element 26. Hereby, complete resonant operation can be performed without receiving the influence of the ripple of input voltage.

Abstract: PURPOSE:To reduce the variance of development conditions with respect to time and position to reduce the degradation of image for development by excessively supplying a magnetic toner onto a recording medium by an excessive toner supply means and removing a part of the magnetic toner with a magnetic force by a toner removing means to perform development. CONSTITUTION:After a magnetic toner 3 is excessively supplied to a recording medium 5 by a toner supply magnet 9, the excessive magnetic toner 3 is attracted to an excessive toner removing magnet 10 by the magnetic force to remove it from the recording medium 5, thus terminating development. In this case, the magnetic attraction acting upon toner particles 3 on the recording medium 5 facing the toner supply magnet 9 by the magnet 9 is made smaller than that acting upon toner particles 3A on the recording medium 5 facing the excessive toner removing magnet 10 by its magnet 10. For the purpose of setting magnetic attractions in this manner, the magnetic force of the toner supply magnet 9 is made weaker than that of the excessive toner removing magnet 10 or the distance between the surface of the recording medium 5 and the excessive toner removing magnet 10 is made shorter than that between the surface of the recording medium 5 and the toner supply magnet 9.

The difference in the quantity of the reflected light detected in the bit 14 of the recording layer 12 and the other part is, therefore, increased and the reproduction signal of high C/N is obtd. The reflectivity of the laser beam in the layer 17 is required as low as possible at this point and more specifically, the integrated reflectivity is preferably <=5%.
