Title: Balance type microwave band amplifier
Inventor: ARAMAKI SHIGETAKA
IPC: H03F3/193
Filed: 1991-04-04
Abstract: PURPOSE:To suppress a ripple in a frequency characteristic by providing a line whose length is 1/2 wavelength with respect to a 2nd harmonic and whose other terminal is connected to ground in terms of high frequency in parallel with a main line at an output side of a unit amplifier via a resistor. CONSTITUTION:Input terminals of a couple of unit amplifiers 5,6 are connected in parallel through a hybrid 7 and main lines 1 at an output side are connected in parallel through a hybrid 8. Each of 2nd harmonic absorption circuits 9,10 is connected to one terminal of a line 3 whose length is 1/4 wavelength with respect to a fundamental wave and 1/2 wavelength with respect to a 2nd harmonic via a resistor 2 in parallel with the main line 1. The other terminal of the line 3 is connected to ground via a capacitor 4 in terms of high frequency so that the 2nd harmonic wave is absorbed in the resistor 2. Thus, the fundamental wave passes through the main line without any change but the 2nd harmonic wave is absorbed in the 2nd harmonic absorption circuits 9,10 and is not given to the hybrid 8 at the output side being a load, then no mixture of the 2nd harmonic wave onto the fundamental wave is caused. Thus, the effect of the 2nd harmonic wave in a nonlinear region is avoided.

IPC: A61B3/10
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To measure an eye refraction without impeding the field of view of an examinee by a face of an examiner. SOLUTION: When measuring the right eye of an examinee, an examiner looks in and operates a video monitor 21 by his right eye. The examinee is instructed to watch a distant point behind the examiner through a frame part 34 mounted on a fitting member 32. Since the face of the examiner is shifted to the side from an optical path of measurement, the examinee can loot at a distant point behind the examiner from a side part of a box 30 without impediment of his look by the face of the examiner. The angle between the look and the optical axis of measurement is about 5 deg. when viewed from the side part of the box 30, and the measurement can be made at a relatively closer angular position from the look. When measuring the left eye, the fitting member 32 is turned to set the video monitor 21 on the opposite side of the box 30, and the examiner watches the video monitor 21 by the left eye.  Since the frame part 34 is on the left side, the examinee looks at a distant point through the frame part 34. Since the position of the frame 34 is in a specified relationship to the optical path of measurement, the look can be kept in a specified relationship to the optical path of measurement.

Title: Demultiplexing device and beam deflecting device
Inventor: KOBAYASHI TETSUO
IPC: G02F1/23
Filed: 1989-03-24
Abstract: PURPOSE:To efficiently enable diffraction demultiplexing operation by crossing the traveling direction of a light beam to be demultiplexed by demultiplexing in an electrooptic material and the traveling direction of progressive wave phase gratings, and providing at least three cycles of phase gratings in section crossing the phase gratings. CONSTITUTION:A couple of electrodes 3 and 4 which extend in one direction are formed on the electrooptic material body 2 which varies in refractive index with an applied electric field and when a high-frequency voltage is applied between those electrodes, the progressive wave phase gratings are formed in the electrooptic material body 2. When an incident light beam is made to travel crossing an electric wave forming this phase gratings, the number of the phase gratings present in the section of the light beam increases substantially and the diffraction efficiency increases. Therefore, many subordinate beams which are frequency-modulated can be separated spatially. Consequently, the electrooptic material element is applied to the demultiplexer device for generating the frequency-modulated subordinate beams, so that the subordinate beams which are modulated at a higher frequency than an acoustooptical element can be generated.

Title: Focus detector
Inventor: MARUTA KEIJI
IPC: G11B7/09
Filed: 1984-04-11
Abstract: PURPOSE:To attain the accurate and stable focus control by receiving the reflected light by two photodetecting parts including three detection parts and giving a specific arithmetic to each detection signal to obtain an error signal. CONSTITUTION:The reflected light is divided into two parts by a beam splitter 11 and received by two photodetectors 12 and 13 including three detection parts set at positions before and after convergent points O1 and O2. When detection signals of each detection part are referred to as A, B, C and D, (A-C)+(D-B) is obtained. With this waveform it is possible to obtain a focus error signal having excellent linearity at a place near a zero-cross point. Here said equation can be replaced with (A+D)-(B+C). Therefore said error signal is obtained by comparing the sum of A and D of detectors 12 and 13 with the sum of B and C of detectors 13 and 12. Thus it is possible to attain the focus control with high accuracy and high stability by an error signal having excellent linearilty at a zero-cross point.

Abstract: PURPOSE:To extend the service life of a built-in battery of a power source built-in IC memory card and to simplify its structure by providing a power source control circuit to start the power source supplying from a power source to a memory control circuit by means of an external data input. CONSTITUTION:In a main body, a semiconductor memory 102, a memory control circuit 104 to input/output data and to control the memory data, and a power source control circuit 101 to make a power source 103 for the memory control circuit to be built-in, and to start the power source supplying from the power source 103 to the control circuit 104 by a data input/output signal between the outside are possessed. Consequently, at the time of the data input/output, since the power source is supplied from the power source to the control circuit, the data can be inputted/outputted in the same way as the normal IC memory card, whereas, in the other case, the power is not supplied from the power source to the memory control circuit. Thus, the useless consumption of the power source can be prevented when the data are not inputted/outputted. Further, since a power source switch, a terminal, etc., are unnecessary, the costs can be lowered, and the constitution can be simplified.
