Title: Surface treating apparatus
Inventor: ONO TETSUO
IPC: H01L21/3065
Filed: 1995-02-13
Abstract: PURPOSE: To miniaturize the apparatus and to make the surface treating speed uniform by forming the surface, parallel to and facing to the sample, from a conductor to make the distance between an arbitrary point in the surface of the sample and the conductor constant for forming the paths of an RF current, flowing through the plasma, uniformly on the sample surface when an RF voltage is applied to the sample. CONSTITUTION: A sample 10 is mounted on a sample base 9. An RF power supply 11 with an oscillating frequency of several hundreds to several MHz is connected to the sample base 9. When the RF voltage is applied to the sample, ions in plasma 8 are accelerated to be incident on the sample 10 and etching proceeds by the energy thereof. At that time, an RF current flows through the plasma, and the current is nearly uniform in the sample surface 10 because the upper wall of a conductor 2 is parallel to the sample, so that the etching speed is also made uniform in the surface.

Abstract: PURPOSE:To carry out the surface sterilization of a toilet stool by making a stink suction fan selectable to clockwise or counterclockwise rotation, and at the time of the clockwise rotation, performing the ozonolysis of a bad odor, while at the counterclockwise rotation, sending a flow of ozone into a stool bowl. CONSTITUTION:When a user is seated on a stool body 10, a seating sensor S feeds a seating detection signal 41 to an input interface D2 of a control part D. Next, at a fan driving part C, if voltage phase in the clockwise direction is impressed on a fan motor (m), a stink suction fan F rotates clockwise, starting its suction of a stink in a stool bowl 10a, while a high voltage generator 19 impresses a voltage on an ozonizer 17, whereby ozone is produced in an ozone generating part G. In succession, when the user separates from the stool after use, the seating sensor S detects this separation, feeding the separation detecting signal to the input interface D2 of the control part D. Then, receiving a driving signal out of an output interface D3 of the control part D, it rotates the stink suction fan F in reverse and simultaneously ozone in the ozone generating part G is ejected into the stool blow 10a.

IPC: B62D5/04
Filed: 1995-02-13
Abstract: PURPOSE: To improve the accuracy of steering torque detection despite being simple in structure as well as to make manufacturing cost so as to be reducible.

Title: Continuous action image display device
Inventor: YAMAMOTO MASAOMI
IPC: G09F19/22
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To prevent reduction of contrast even in the case of receiving a light. SOLUTION: A static image signal has little different time with respect to each of display devices 6, and is an image signal which becomes a continuous action as a whole image when seen from a moving body such as a train. Since the image is given as an electric signal, rewriting of the content of a picture memory is sufficient for changing the content of the image. Therefore, any image can be displayed and plural images can be displayed, too. A multiple image is prevented by shortening an image display time compared with a display suspending time of the image, to thereby obtain a more natural and clear image. Light absorbers 104 as a contrast improving means are arranged on the periphery of the display device 6.  Since the external light, such as the light of a train or the like, can be prevented from being superimposed on an image display face by the light absorbers 104, the contrast of the image can be improved.

Title: Method for refining molten iron
Inventor: HORII KAZUHIRO
IPC: C21B5/00
Filed: 1993-02-12
Abstract: PURPOSE:To obtain a refining method for a molten iron which can recover Mn and save flux by classifying a slag generated after refining in a converter through dephosphorization process as a pretreatment with (%MnO) in the slag and limiting the recycle position to each slag. CONSTITUTION:The high MnO slag having >=10% is returned back to a process as much as possible in order to improve the recovery efficiency in the total processes, therefore, in the case of returning back to the converter, since the Mn control precision is deteriorated and the produced slag quantity is increased in the atmosphere having high oxidizing degree, this slag recycle is disadvantageous. Therefore, this slag is not returned back to the converter, but returned back to disphosphorization desiliconizing processes. Further, by feeding the low MnO slag having <=10% into a blast furnace, since Mn in the tapped iron is suitably improved, this slag is directly fed into the blast furnace, and the saving of the feed raw material and the indirect saving of the flux quantity by adding as a sintering raw material can be obtd.

Title: Optical system switching type camera
Inventor: WAKABAYASHI HIROSHI
IPC: G03B17/12
Filed: 1985-02-12
Abstract: PURPOSE:To adjust easily an optical system by providing a coupling cut off mechanism for breaking coupling between a connecting/disconnecting mechanism and a sub-optical system optionally. CONSTITUTION:When the sub-optical system 4 is at complete shunting position or at complete inserting position, the coupling part 27e of a driving member 27 is coupled to the second coupling face 50c. When the driving member 27 is lifted along an axis 10a resisting energizing force of a spring 30 under this condition, coupling of the coupling part 27e to the second coupling face 50c is released, i.e. coupling to a sub-optical system connecting/disconnecting mechanism 27 is released, and it is shifted to a position opposite to the first small diameter face 50e. As the first small diameter face 50e is outside of the oscillation locus of the coupling part 27e, the driving member 27 can be connected or disconnected manually at will. Thus, the sub-optical system 4 can be connected or disconnected independently of the connecting/disconnecting mechanism 27, and the optical system 3 can be adjusted easily.

Abstract: PURPOSE:To reduce a power consumption, and to use the subject mixer even at the time of a power interruption by specifying the gain of an input amplifier, and the product of the gain of the input amplifier and the gain of an output amplifier. CONSTITUTION:An input amplifier 10 inputs a signal through an input resistance Rti (i=1-18), and operates an amplification by a feedback resistance Rgi. An output amplifier 12 uses the resistance Rs of corresponding analog switches S1-S64 as the input resistance, and operates the amplification by a feedback resistance Rfj (j=1-8). Then, the gain alpha of the input amplifier 10 is set to be less than 1, and the gain beta of the output amplifier 12 is set so that alphabeta=1 can be obtained. For example, when the gain alpha is 1/10, the Rti and Rfj are 100kOMEGA, and the Rgi and Rs are 10kOMEGA, and the gain beta is set to be 10. At that time, currents running through the analog switches are 1/10. and then the current consumption of the entire cross point mixer can be reduced. And also, the gain beta is set to 10, so that the amplitude of an output signal can be held to be almost constant.

Title: Detection circuit of drop-out
Inventor: UMEKI NOBUMOTO
IPC: G11B7/00
Filed: 1978-03-06
Abstract: PURPOSE: To obtain the detection signal of the drop-out of time-axis modulation signal by supplying the digitized time axis modulation signal to a monostable circuit.  
     CONSTITUTION: The FM signal Sb having undergone shaping is supplied to a monostable multivibrator 24 of rise trigger type. In this case, this multivibrator 24 is made in retriggerable type and its inversion period (r) is made longer than the 1-cycle period of the FM signal Sf when the maximum period is reached and shorter than the 1.5-cycle period. Hence, the monostable multivibrator 24 is triggered at each rising of the signal Sb and since its inversion period (r) has been selected, the output Q 24  of the multivibrator 24 delays by nearly T/2 and becomes 0 when there is drop-out.
