Title: Method for stabilization of frequency interval of laser apparatus
Inventor: SHIMOZAKA NAOKI
IPC: H04B10/564
Filed: 1990-01-31
Abstract: PURPOSE:To stabilize the oscillation frequency interval of a plurality of laser apparatuses at two unequal intervals by a method wherein, out of a reference pulse train obtained when a frequency scanning beam is passed through an optical resonator, pulses which are selected arbitrarily every several pieces are used for a control operation as a new reference pulse train. CONSTITUTION:A beam radiated from a distributed reflection type laser 1 provided with a 1.55mum-band phase control region is transmitted through an isolator 3; after that, it is divided into a first output beam and a second output beam by using a beam splitter 4 in a power ratio of 1:1. The first output beam is passed through a quartz-glass etalon sheet 5 whose reflection factor on both faces has been set; after that, it is incident on a first photodetector 6. A pulse-shaped beam is input to the first photodetector 6 at the time when the frequency of the distributed reflection type laser 1 provided with the 1.55mum-band phase control region coincides with the resonance frequency of the etalon sheet 5 during one cycle of an output signal from a sawtooth wave generator 2. However, the peak voltage of an output from the sawtooth wave generator 2 is adjusted in such a way that the number of pulses in one cycle becomes four. At a control operation, three laser apparatus are stabilized to a first pulse, a second pulse and a fourth pulse.

IPC: G01N21/47
Filed: 1992-02-06
Abstract: PURPOSE:To measure the intensity of light limited in a specific direction by making the aperture angles of photoreceptor elements belonging to a group positioned on the central side of an optical axis larger than those of photoreceptor elements belonging to the opposite-side adjacent group of the group on the central side of the optical axis.

The innermost group 1a is composed of, for example, seven fan-shaped photoreceptors 2, with their circular arc sections being concentrically arranged. Similarly, the groups 1a-1c are arranged in one row. The chords y11, y21, and y31 of outermost circular arcs of the groups 1a-1c are designed so that they can become y11<y21<y31 and the outermost circular arc y31 of the group 1c can become equal to or smaller than about 0.18 time of the focal distance of an ftheta lens. The apertures of the groups 1a-1c are made different from each other, with that of the innermost group 1a being designed to the largest. In addition, the innermost chords of the groups 1b and 1c are made smaller than the chords y11 and y21. Therefore, the polarized-direction components of a polarized laser beam can be efficiently detected by condensing front scattered light rays generated when sample particles are irradiated with the polarized laser beam.

Title: Discharge lamp light-on circuit
Inventor: DOBASHI MASAHIRO
IPC: H05B41/18
Filed: 1978-02-27
Abstract: PURPOSE:To prevent the shortening of lifetime and the secular light-on start time lag of a discharge lamp, by connecting a plurality of starting switches in parallel with each other across both the electrodes of the discharge lamp. CONSTITUTION:When a voltage is applied from a power source 5 to the fluorescent (discharge) lamp 1 through a stabilizer 4, more easily discharge starting one of two glow switches 6, 6 coupled in parallel with each other starts discharge. One bimetal-made electrode of the glow switch is displaced into contact with the other electrode because of the heat of the discharge. As a result, the discharge stops and a short-circuit current flows to heat the electrodes 2, 3 of the lamp. Then, the glow switch 6 operates to separate its electrodes from each other. Simultaneously, a high surge voltage is applied across the heated electrodes of the lamp 1 and the lamp starts discharge. According to this method, the maintenance of the discharge lamp is facilitated.

Abstract: PURPOSE:To perform high-precision measurement by throwing grains in a measuring tank to a set value a little bit less than a target value of the measurement, making a comparison between this measured value and the target value,  and adding grains as many as the found deficiency with a small-capacity correcting measure. CONSTITUTION:When grains are supplied from a gain intake 2 and a gate 3 is opened to fill a service hopper 1 with the grains, the grains are thrown in the measuring tank through a large throw-in gate 5 and a small throw in gate 6.

For large-amount supply, the gate 5 is opened and for small-amount supply, the gate 6 is opened with the gate 5 closed and grains are thrown, bit by bit, from the small hole 5a until the set value. Then, the weight of the thrown grains is measured and compared with the target value of measurement to find the number of times of corrections and a throwing device for specific-capacity correction makes corrections.
