Abstract: PURPOSE:A saccharide solution obtained by saccharification of cellulose with an enzyme is treated by ultrafiltration, then with a membrane for reverse osmosis to enable efficient concentration of high-concentration saccharide solution. CONSTITUTION:A saccharide solution obtained by saccharifying cellulose with an enzyme such as cellulase is treated with an ultrafiltration membrane of less than 20,000 fractionation molecular weight to divide into a concentrate containing the enzyme as well as unhydrolyzed cellulose and a filtrate of about 6-7% total saccharide concentration. The concentrate is made to turn back to the saccharification process. The filtrate is treated with a reverse osmosis membrane to give a saccharide solution of 15-20 total saccharide concentration. As the reverse osmosis membrane, is preferably used a heat-resistant and pressure- resistant one of cellulose acetate in general. When a solution of higher concentraion is required, the reverse osmosis is divided into 2 stages where the membrane of more than 99% saccharide separation is used in the first stage and that of 30-90% in the second to give a solution of about 30-40% total saccharide concentration.

Title: Frequency modulating circuit
Inventor: IZAWA KAORU
IPC: H03C3/02
Filed: 1988-03-31
Abstract: PURPOSE:To obtain an optimum cut-off frequency to correspond to an arbitrary central frequency and to remove a harmonic component at a same level without fail by obtaining constant correlation between the central frequency of a modulator and the cut-off frequency of an LPF. CONSTITUTION:A current (i), which is obtained by current-converting in input signal Vi, is overlapped to a constant current Io by an input control part 15 and a modulating input current Ioi, which is composed of a current Io and (i), is generated. In a frequency modulator MOD20, a frequency modulating output VFM, which is composed of a central frequency fo to correspond to the current Io in the current Ioi and a central frequency change to correspond to the amplitude change of the current (i), is generated. A cut-off frequency fc is controlled with the current Ioi by an LPF40 and an unnecessary frequency component is removed from the output VFM. Accordingly, the central frequency fo of the MOD20 and the frequency fc of the LPF40 obtain the constant correlation with the current Ioi as a medium and the frequency fc to correspond to the change of the frequency fo is optimumized. Then, regardless of the fluctuation of the frequency fo, the unnecessary harmonic component is removed.

Abstract: PURPOSE:To provide the observation depth in response to the distance to a test object by stably changing the brightness aperture of the objective optical system of an endoscope with a simple structure. CONSTITUTION:Radial notches are provided on the periphery of the aperture hole 13 of a flat plate 12 made of two-polarity SMA, and the shapes of burr sections 15 formed around the aperture hole 13 according to the notches are stored.

Title: Loading device for cartridge
Inventor: OKABE KATSUHIKO
IPC: G11B17/04
Filed: 1989-03-30
Abstract: PURPOSE:To prevent a cartridge from being discharged carelessly by providing an electromagnet which attracts and holds a lock lever at the restricted position of a slide plate when an ejecting member operates while a recording medium is being driven. CONSTITUTION:When the ejecting member 25 is pushed in in a right direction with intent to execute the discharge of the cartridge 12 by mistake while an optical disk is being driven, a photosensor 48 detects the member 25, and in addition, because a cartridge holder 11 is positioned at a position shown in a figure, the electromagnet 47 attracts the arm of the lock lever 40. On the other hand, since the part to be pushed of the lock lever 23 is pushed by the pushing part of the member 25, the restriction of the engaging piece 17 of the slide plate 14 is intended to be released. But since the attractive force of the magnet 47 to keep the restriction of the engaging piece 17 is larger than force to release the restriction of the engaging piece 17, the lever 40 keeps the engaging piece 17 restricted. As the result, the force to lift the cartridge holder 11 is not generated, and accordingly, there is no possibility that the cartridge 12 is discharged by mistake.
