Title: Local oscillator
Inventor: KONDOU HIDETOSHI
IPC: H03L7/16
Filed: 1983-11-08
Abstract: PURPOSE:To perform electrical switching of many frequencies in a simple way by varying the oscillation frequency of a voltage control oscillator constituting a phase synchronizing oscillator by an external command signal to multiple frequencies and setting these frequencies at an integer-fold level as high as the oscillation frequency of a crystal oscillator. CONSTITUTION:When a high command signal for control of frequency is applied to a terminal 17, the oscillation frequency of a voltge control oscillator VCO is set at f1. Then a phase synchronizing oscillator 12 has phase synchronization with an m-degree higher harmonic wave of an oscillation frequency fX of a crystal oscillator 11. Thus a stable local oscillation signal of a frequency f1 is obtained through an output terminal 16. When a low command signal for control of frequency is applied to a terminal 18, the VCO oscillation frequency is set at f2. Thus the oscillator 12 has the phase synchronization with an n-degree higher harmonic wave of a frequency fX. Then a stable local oscillation signal of a frequency f2 is obtained through the terminal 16. Thus it is possible to realize a local oscillator which can switch electrically double frequencies in simple constitution.

IPC: A61K35/16
Filed: 1984-10-05
Abstract: PURPOSE:To carry out the separation and purification of ceruloplasmin, in high efficiency, by contacting chilled water with a ceruloplasmin-containing granule prepared from plasma, removing soluble components therefrom, separating ceruloplasmin with an anion exchange material, and precipitating the crystal of ceruloplasmin by dialysis. CONSTITUTION:Granules containing ceruloplasmin and prepared from plasma are made to contact with chilled water to remove the soluble components, and the obtained aqueous solution containing ceruloplasmin is developed by chromatography using an anion exchange material. The ceruloplasmin fraction is collected, and the aqueous solution of ceruloplasmin is dialyzed to precipitate and separate the ceruloplasmin crystal from said solution. Water-soluble protein impurities such as albumin, prealbumin, alpha1-globulin, etc. which are hardly separable by other methods can be removed by washing with chilled water. Ceruloplasmin useful as a remedy for hypoplastic anemia can be separated and purified from a raw material having low ceruloplasmin content, in high yield, by combining the above process with the subsequent purification process.

Title: Focus detector
Inventor: FURUMIYA MASAAKI
IPC: G11B7/09
Filed: 1989-08-15
Abstract: PURPOSE:To highly accurately detect a focus state by providing the focus detector with plural photodetecting means for receiving a luminous flux divided into two parts by a prism arranged in the optical path of reflected light separated by a beam splitter. CONSTITUTION:In the focal state in which an optical disk 25 is set up on the focus position of an objective lens 24, reflected light made incident from the optical disk 25 upon a Foucault prism 26 through the beam splitter 23 is collimated beams. Since the oblique faces 26a, 26b of the prism 26 are formed so that the incident angle of the collimated beams is set up so as to be slightly smaller than a critical angle, the light made incident upon the prism 26 is divided into two beams and the beam in parallel with the oblique faces are shaped, projected and made incident upon photodetectors 27, 28. Thereby, a signal FE=0 is obtained from a differential amplifier 29 in this focal state. In a state separating the optical disk 25 from the focus position of an objective lens 24, a signal of FE > 0 is obtained from the differential amplifier 29, and in the approached state, a signal of FE < 0 is obtained. Thus, the focus state can be highly accurately detected.

Title: Radio receiver
Inventor: TSUKAMOTO OSAMU
IPC: H04B1/10
Filed: 1981-12-28
Abstract: PURPOSE:To eliminate interference noise specific to the superheterodyne system, by switching an intermediate frequency amplifier section, in response to the frequency of an interference wave. CONSTITUTION:Intermediate frequency amplifier circuits 3, 4 having center frequencies FA, FB respectively are selected for one with a changeover switch 5 and connected between an intermediate frequency converter 2 and a detection circuit 6. When the normal center frequency FA is received and subject to image frequency interference and spurious interference, the switch 5 is selected to the center frequency FB. Thus, the interference wave is shifted to the outside of the pass band of the intermediate frequency amplifier circuit and the wave is sufficiently attenuated for the interference. Since the noise is processed only through the extension of the intermediate frequency section design and manufacture of the circuit are attained easily.

IPC: H04N1/32
Filed: 1983-11-10
Abstract: PURPOSE:To enable to use a small-sized and low-priced motor at a low speed for shifting an original by making the time which is required for shifting one line of the original almost coincide to the accumulated time of a light sensor, and by reading only data which are accumulated at the time of shifting of the original. CONSTITUTION:A CPU1 sends out a signal (a) which indicates one-line shifting start to an original 10 to a motor controlling part 2 in order to read one line and the data accumulated so far to a reading part 3, and outputs a signal (b) which begins the new accumulation. The controlling part 2 shifts the one-line original 10 gradually within the accumulated time of which a light sensor re- quires. When the accumulated time elapses after starting the accumulation of the reflected light of the original 10 which is irradiated by a light source 9, the CPU1 outputs a signal (c) which transfers the data read by the reading part 3 to a buffer A5 and a buffer B6. When transportation to the buffer 5 has completed, an operating part 7 executes redundancy suppression processing of the data inside the buffer, and stores the data in a memory 8. The buffers 5 and 6 are used alternately by the reading part 3 and the operating part 7.

IPC: G01N21/88
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To observe a fine fault which cannot be observed by an optical microscope by the minimum labor hour. SOLUTION: When a conveyor 32 receives and conveys a reticle R from a storage unit and delivers it to a fault inspecting unit 30, the unit 30 inspect the presence or absence of the fault of a pattern on the reticle R.

The unit 31 images the pattern on the reticle R where the fault of the pattern is discovered, and stores the image information of the pattern fault in a memory 51. Thus, when the image information of all the fault of the patterns on the reticle R is stored in the memory 51, the conveyor 52 removes the matter to be inspected from the unit 31, and restores it in the storage unit.
