Title: Lens driving device of camera
Inventor: MOTOTSUGU RIYUUZOU
IPC: G02B7/08
Filed: 1983-04-01
Abstract: PURPOSE:To attain a stable focusing operation, to set a blind sector width to zero, and to raise the focusing accuracy by adjusting the gain of an amplifier in accordance with an output of a photodetector. CONSTITUTION:The reflected light of a light emitting diode 4 is converted by photodetectors 1, 2, and converting outputs I1, I2 are obtained by amplifiers 5, 6. After inputting the outputs I1, I2 to variable gain amplifiers 7, 8, an adding signal I1+I2 is made by a detector 9 in synchronization with an oscillator 3, as compared with reference voltage 11 by an operating device 10, the gain of the amplifiers 7, 8 is varied so that I1+I2 becomes constant, and thereafter, focusing is obtained by driving a motor 14 so as to become I1-I2=0 basing on an output I1-I2 of a synchronizing detector by an operating device 13, therefore, focusing which is stable and has high accuracy is obtained irrespective of a variation of an output level of the photodetectors 1, 2 in accordance with a distance of an object.

Title: Container for radioactivation analysis
Inventor: HIRAI IESADA
IPC: H01L21/66
Filed: 1989-03-08
Abstract: PURPOSE:To improve measurement accuracy of heavy metal concentration by constituting a container main unit which is provided with sealing means, a cover, and a wafer fixing plate consisting of silicon which elastically retains the wafer which is retained within the container main unit and is to be inspected. CONSTITUTION:The title container consists of a container main unit 11 which is provided with a sealing means and consists of silicon, a cover 13, and a wafer fixing plate consisting of silicon which elastically retains a wafer 10 to be inspected which is stored within the container main unit. Namely, since silicon can achieve ultra-high purity easily, contamination of the wafer 10 due to the container can be reduced. Also, since the half life of a radioactive element which is produced by radioactivation is short, radiation from the radioactive element remaining until measurement becomes scarce, thus enabling impurities of the wafer 10 to be measured accurately. Thus, it becomes possible to analyze and measure a small amount of heavy metal impurities which exist within the wafer material or on the surface of the wafer with improved sensitivity and accurately.

Title: Method for preventing baking of picture display tube
Inventor: KANAZAWA MASARU
IPC: H04N3/22
Filed: 1988-03-11
Abstract: PURPOSE:To prevent baking caused at a border with a blank part of a display plane simply by eliminating the deviation of the aspect ratio by the adjustment of deflection amplitude of a monitor display tube and eliminating the baking of the border of non-display part caused on the display screen based on the difference from the aspect ratio through the addition of an intermediate level signal. CONSTITUTION:In the case of displaying a picture signal having a signal waveform for one scanning line comprising a blanking period t1 and a video signal period t2 onto a display screen of a monitor with a different aspect ratio, when a slight deviation in the aspect ratio caused in displaying a converted output picture signal subject to scanning rate conversion with a simple ratio close to the difference from both the scanning rates is adjusted by more or less expanding/contracting the deflection amplitude of the monitor display screen, a blank period giving no display due to the difference between the flyback time t3 of the monitor and the blanking period t1 in the scanning period t1+t2 based on the difference from the aspect ratio of the picture signal and the monitor display screen is produced. Then an intermediate level signal with a proper period length taking the over scan of the monitor display screen into account is added to the nondisplay blank period. Thus, baking of a display screen fluorescent substance layer caused at the border of the blank part is prevented.

Title: Optical amplifier
Inventor: UEHARA DAISUKE
IPC: H01L27/15
Filed: 1995-03-16
Abstract: PURPOSE: To obtain an optical amplifier in which the intensity of optical signal can be amplified appropriately regardless of fluctuation in the number of multiplexed optical signals. CONSTITUTION: A wavelength multiplexed optical signal amplified through an optical fiber added with erbium is inputted to a narrow band variable wavelength filter 11 and an optical signal of one wavelength is extracted. When the intensity of an extracted optical signal is lower than a predetermined threshold level, a pass wavelength control circuit 15 alters the central pass wavelength and retrieves an optical signal having intensity higher than the threshold level. An optical output control circuit 24 controls the quantity of exciting light such that the retrieved optical signal has a predetermined intensity. Since the gain is controlled with reference to an optical signal having intensity higher than the threshold level, the gain is not increased over a required level and the intensity of optical signal can be amplified appropriately.

Abstract: PURPOSE:To collect only data which are necessary for analysis in a fatigue test by calculating successively the compliance of a test piece from stress and strain which operate on the test piece and collecting data every time the amount of its variation attains to a specific value. CONSTITUTION:A testing machine 1 places repeatedly a load on a body to be tested and measures data on the resulting stress, strain, etc., which are supplied to a CPU4 through an AD converter 2 and an input/output interface 3.
