Title: Reference voltage generating circuit
Inventor: YAMAZAKI KOJI
IPC: G05F1/56
Filed: 1984-11-21
Abstract: PURPOSE:To make the minimum action electric power supply voltage of a minimum voltage generating circuit in a reference voltage generating circuit into a low voltage by employing a constant voltage generating circuit having a temperature characteristic and a differential amplifier. CONSTITUTION:A system in a feedback amplifier constituted of a differential amplifier 2 and the 1st output transistor 3 is of a negative feedback amplifier, and acts so as to be VI1=VrI2VI1. The VI1 is the input voltage of the negative input terminal of the differential amplifier and also the output voltage of the constant voltage generator circuit 1. Assuming that the temperature characteristic of a voltage VD1 and that of the voltage VI1 are -2mv/ deg.C each, (VI1-VD1) becomes constant irrespective of the temperature. If the characteristic of the 1st output transistor 3 is equal to that of the 2nd output transistor 6 the output current I2 of the 2nd output transistor 6 attains I1=I2. Where the characteristic of a current setting resistance 4 is the same as that of a voltage setting resistance 7, a voltage V01 can be stabilized with respect to the fluctuations of an electric supply voltage and the temperature.

IPC: G03H1/22
Filed: 1993-09-10
Abstract: PURPOSE:To prevent the adverse influence of the interference, etc., of reconstructed image formation with each other on the reconstructed images and to obtain the reconstructed images having high resolution without generating ghost-like noise light by calculating the diffraction efficiency characteristic of plural hologram components and selecting optimum reconstruction conditions in accordance therewith. CONSTITUTION:The hologram reconstructed images are formed by irradiating the hologram consisting of the plural hologram components with reconstructing waves. While the reconstructing waves are based on the luminous fluxes conjugate with reference light at the time of hologram formation, the incident angle of the reconstructing waves is adjustable by adjusting a reconstructing wave deflecting mirror 6. The state of the intensity change of the reconstructed image according to a change in the reconstruction conditions is first calculated by arithmetic operation as the diffraction efficiency characteristics at each of the respective hologram components. The reconstruction conditions under which the intensity difference of the reconstructed images from the one hologram component attains a predetermined value are selected in accordance with the results of the calculation. The reconstruction of the hologram is executed under the selected reconstruction conditions.

While the control is indicated for KANA/KANJI conversion if the terminal 08 is set to ''0''. In such a way, the input of character strings is possible with no mistake of key operation by using a means which feeds the indication for output of character strings in KANA and a means which feeds the indication for the output of character strings in KANJI respectively.

Title: Current effective value measuring circuit for cycle control type electric power controller
Inventor: MARUO TETSUHIRO
IPC: G01R19/02
Filed: 1986-10-20
Abstract: PURPOSE:To accurately measure a current effective value by finding the effective value of an intermittent current from the output voltage signal and threshold signal of a frequency counter and a holding circuit. CONSTITUTION:The intermittent current after cycle control is converted by a comparator 11 into a rectangular wave signal which is at H level for the duration of a current exceeding a threshold level and a wavelength measuring circuit 12 converts it into a voltage signal proportional to the duration of the rectangular wave signal. This voltage signal is held by a holding circuit 13 until the leading point of a next voltage signal and inputs this voltage signal and the threshold signal to find the crest value of a sine wave current waveform. Then, an arithmetic circuit 15 is provided which computes the effective value of the intermittent current from the found crest value and the output signal of the frequency counter 14 which inputs the output signal of the circuit 11 and outputs the effective value. The effective value of the intermittent current is therefore found from two instantaneous values of a sine wave current waveform in either half cycle of each intermittent current cycle, so the effective value can be measured without distorting the intermittent current waveform.
