Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To suppress the occupied area from increasing and facilitate addition, change and expansion of vacuum treating chambers with reduced space by providing a sample inlet/outlet chamber, vacuum transport means and first vacuum treating chamber nearer to the inlet/outlet chamber than 1 first treating chamber. SOLUTION: An air transport robot 9 of a cassette block 10 is moved on a rail 91 to transfer a sample 3 from a lead cassette 12A onto a scoop. After aligning the orientation flat by an orientation flat alignment 12A, the sample 3 is again mounted and carried in a load lock chamber 34 of a vacuum treating section 30 with an upper closed hermetic space by a sample push-up mechanism.

Title: Calculation method for correction data for compressing dynamic range of radiant ray picture
Inventor: NAKAZAWA MASAYUKI
IPC: G06T1/00
Filed: 1992-09-11
Abstract: PURPOSE:To obtain the dynamic range compression correction data calculation method for a radiant ray picture by setting correction data to a predetermined value when a signal level is larger than or a smaller than a reference level. CONSTITUTION:Correction data are set as A(x)=F(Sx, Py1), which is a function of a reference level Sx and a value Py1. Concretely, in the case of, e.g. i) Sx>Py1, the function is expressed as F(Sx, Py1)=Sx-Py1 and in the case of ii) Sx<=Py1, the function is expressed as F(Sx, Py1)=0. No correction is applied to a portion (much of X ray transmission quantity) where a signal level is higher than the reference level and the dynamic range is compressed to only a portion (less of X ray transmission quantity) where the signal level is lower than the reference level. Since the correction data result from a difference between the reference level and the signal level at a region where the signal level is less than the reference level, the correction data are a continuous function of the signal level before and after the reference level. Thus, the dynamic range is compressed without causing a false picture.

Title: Laminated piezoelectric actuator element
Inventor: KAMATAKI HIROTERU
IPC: H01L41/09
Filed: 1989-09-20
Abstract: PURPOSE:To protect an actuator element against damage caused by the concentration of shearing stress on it even if it is large by a method wherein inner electrode layers interposed between piezoelectric ceramic plates and other inner electrode layers in contact with a protective layer are specified in thickness. CONSTITUTION:The thickness of an inner electrode layer 2 interposed between piezoelectric ceramic plates 1 is made 1/50-1/10 of that of the ceramic plate 1, and the thickness of an inner electrode layer 2a in contact with a protective layer 4 is made 1/10-1/5 of that of the piezoelectric ceramic plate 1. Therefore, the concentration of shearing stress induced in an actuator element when a direct current voltage is applied to it is absorbed by the inner electrode layers without decreasing the electrical field in intensity and the concentration of stress can be moderated. By this setup, an actuator element of this design can be improved in yield without causing damage or insulation failure to it.

Abstract: PROBLEM TO BE SOLVED: To suppress the temperature coefficients of current of coupled current source and to supply a stable current even when ambient temperature is fluctuated by coupling the output current of the stabilized current source of positive temperature coefficient and that of the stabilized current source of negative temperature coefficient. SOLUTION: A VBE multiplier type bias circuit 20 is composed of a transistor 21 and resistors 22-24, and an output voltage is supplied to a current source 10a. A band gap reference type bias circuit 40 is composed of transistors 41-43 and resistors 44-47, and an output voltage is supplied to a current source 10.

IPC: H04B1/10
Filed: 1989-09-20
Abstract: PURPOSE:To offer the best video image to the user hy constituting an automatic video image noise reduction circuit utilizing a control voltage to a tuner of an AGC circuit. CONSTITUTION:A voltage in response to an input electric field strength to an antenna 1 is outputted from an automatic gain control circuit(AGC) 2 to a terminal TP 15 and when an input signal to the antenna 1 is weak and noise starts appearing on the screen of a television receiver, the highest voltage is applied to a high frequency amplifier circuit 3a of a tuner 3 and the tuner 3 acts at a highest gain. When the input signal is stronger, the output voltage from the AGC circuit 2 is decreased to decrease the gain of the tuner 3. Thus, the gain of the high frequency amplifier circuit 3a of the tuner 3 is controlled by an AGC output voltage to keep the input signal level to an intermediate frequency amplifier circuit 4 nearly constant. Thus, the best video image is observed.
