Abstract: PURPOSE:To provide an optical frequency mixer, which has large admissibility to unnecessary incident light such as background light as wells as output characteristics having excellent linearity to the intensity of incident light and in which gain modulation can be set deeply. CONSTITUTION:The mixing of the frequency of the intensity of incident light and the frequency (f3) of an AC signal generated from a signal generator 200, frequency mixing in the product arithmetic operation of both signals, is carried out by the photoconduction type photodetector of a light-receiving section 100. One of the frequency components of the sum and difference of the frequency of both signals obtained as the result of the product arithmetic operation is selected and extracted by using a frequency selector 400. One light signal having an AC component (frequency=f1) may also be used or two light signals having each different frequency (frequency=f1, f2) components in light intensity and being projected into aproximately the same light-receiving regions of the photoconduction type photodetector may also be employed as incident light signals.

Abstract: PROBLEM TO BE SOLVED: To provide a safe antibacterial and deodorant composition having a deodorizing effect to every malodor and an antibacterial effect by mixing basic zinc carbonate or zinc oxide with hydroxy carboxylic acid at specified values of a mol ratio and pH to form an antibacterial and deodorizing component. SOLUTION: Basic zinc carbonate or a zinc compound of zinc oxide and hydroxy carboxylic acid are combined at a proportion of a mol ratio of 1:0.7-1:5, and pH is set to 4-9, preferably to about 5-8. When the quantity of hydroxy carboxylic acid is below the above range, a zinc compound is deposited not to obtain satisfactory deodorizing effect and antibacterial effect, and when it is too much, the quantity of ph regulator used is increased to be wasteful. This composition is added to designated water, and stirred by a magnet stirrer to evaluate the performance. As a result, the composition is excellent in solubility, liquid appearance, stability, an ammonia deodorizing property, hydrogen sulfide deodorizing property and antibacterial property.

Abstract: PURPOSE:To reduce the light quantity loss, by providing an air reverse lens in the transparent material and by fixing the light transmission cable to the transparent material into one body so that the input end face of the optical fiber may be positioned near the focus of this lens. CONSTITUTION:A transparent material which is superior in transmittance of light and heat and has a low absoptivity such as acrylic acid resin and polymethyl methacrylate (PMMA) is used to form condensing head part 1. This condensing head part is a plate material and has space (air lens) 2 scooped out into a concave lens form. Light transmission cable 4 is fixed to condensing head part 1 into one body so that the input end face of the optical fiber may face just the condensed light in the position of focus F in condensing head part 1 or near it, desirably, just before focus F. Thus, since the condensing path is in the optical system forming material, the light quantity loss of the condensing head part can be reduced in comparison with the optical system consisting of the ordinary lens, the reflective mirror, and so on.

Abstract: PURPOSE:To realize the phase and the phase difference with high accuracy by storing a sample value obtained from analog-digital conversion into a memory and extracting a sample value string having a desired phase difference corresponding to the input among the stored values. CONSTITUTION:A signal sample value data is written in a storage memory SM via a data bus DB1 at each sampling period Ts/N(DELTAT) while its address is revised one by one, where N is a channel output number. A data read out of the storage memory SM is fed to a buffer memory BM in the order of channels where it is stored. while a channel memory CM1 is in the input state, a channel memory CH2 is in the output state, each state takes over to each other at each output period to reduce the processing time of the channel output read processing and the independency of the synchronizing system of the input and output. The phase difference setting is decided by designating an address in reading a data from the storage memory SM.
