Title: Carriage drive mechanism for floppy disk device
Inventor: FUJIOKA MASAHIKO
IPC: G11B21/02
Filed: 1986-01-31
Abstract: PURPOSE:To attain the fine adjustment of the position of a carriage by performing the fine adjustment of a bearing stand supporting one end of a lead screw in the carriage drive mechanism of a lead screw system. CONSTITUTION:When a stepping motor 12 rotates and drives, the lead screw 13 rotates. The rotation is converted into a linear movement due to the action of a ball 15, and the carriage moves linearly. The one end of the screw 13 is pushed on the bearing stand 24, whose bearing part is recessed conical, through a rigid ball 23. The other end of the screw 13 is recessed conical, and the recessed part is provided with a lubricant such as glease and the rigid ball 23. Here the bearing stand 24 is of a screw structure capable of fine movement with respect to an actuator 20. Accordingly, if the bearing stand 24 minutely rotates to shift in the shaft direction of the screw 13, the screw 13 rotates through the rigid ball 23. As a result the carriage 10 minutely moves together with the rotation of the screw 13. Thus, if the bearing stand is subjected to fine adjustment, the position of the carriage 10 with respect to a base 11 can be relatively adjusted.

Title: Manufacture of semiconductor device
Inventor: KASAHARA KENICHI
IPC: H01L21/768
Filed: 1984-02-06
Abstract: PURPOSE:To prevent reduction in input resistance by a method wherein a recessed part is formed on the dielectric film provided between the gate and the semiconductor element of an MISFET, and a metal wiring is formed between said gate and semiconductor element in the state wherein a photoresist is left on the recessed part. CONSTITUTION:An SiO2 film 19 is formed between an MISFET12 and a PIN photodiode 13. Then, a recessed part 28 is formed using a photoresist 27 as a mask, and a semiconductor InP substrate 11 is removed by performing an etching in the depth of approximately 1mum. After the photoresist 27 has been removed, a photoresist 29 is applied again. Then, a patterning is performed in such a manner that the photoresist 29 is left on the recess 28 only, and after Al has been vapor-deposited, an electrode 24 is formed using a photoresist. Subsequently, when the photoresist is dissolved, a part of the electrode 24 takes the form wherein it comes up from the semiconductor InP substrate 11 at the recessed part 28, and the current running to an electrode 22 from an electrode 20 is shut off, because an inversion layer is not formed on the substrate located under the electrode 24, thereby enabling to prevent the reduction in input resistance of the MISFET12.

Title: Displacement measuring method
Inventor: KODAMA YOSHIAKI
IPC: G01B11/22
Filed: 1983-02-10
Abstract: PURPOSE:To permit easy and prompt displacement measurement even in places under adverse environmental conditions by a method wherein laser beams from two light sources at different positions are focused to the same point on the object to be measured to measure the separation distance between two radiant points which are produced due to displacement of the measured object. CONSTITUTION:First, a screw 1 is rotated at a low speed so that no cavitation will occur. In this state, angles of laser projectors 6a, 6b are controlled to focus laser beams to the same irradiation point on the screw surface. This operation is repeatedly carried out over the entire length of the screw 1, and angles of the laser projectors 6a, 6b are displayed on and stored in a laser angle display 9. When the number of revolutions of the screw 1 is so increased as to generate cavitation, two radiant points are produced. A separation distance between those radiant points is measured by a video scaler 17 thereby compute a depth of cavitation.

Title: Vortex detecting circuit
Inventor: MISUMI KATSUO
IPC: G01F1/32
Filed: 1993-02-08
Abstract: PURPOSE:To enhance detection sensitivity and frequency response by detecting the variation of fluid temperature by a second temperature-sensitive resistive element and heating a first temperature-sensitive resistive element at a temperature, higher by an amount corresponding to a resistance component set by a variable resistor, thereby decreasing the heating current. CONSTITUTION:Temperature-sensitive resistive elements 21, 22 for detecting the fluid temperature are inserted between variable resistors 7, 8 and the earth in a bridge circuit and the elements 21, 22 are fixed to a vortex generating object placed in the flow of fluid in order to detect the fluid temperature. Since the resistances of the vortex detecting elements, i.e., the temperature-sensitive resistive elements 1, 2, and the liquid temperature detecting elements, i.e., the temperature-sensitive resistive elements 21, 22, vary simultaneously according to the variation of the fluid temperature, the variable resistors 7, 8 are required to heat the elements 1, 2 only by an amount corresponding to the temperature rise required for vortex detection. This constitution allows the decrease of current required for heating the elements 1, 2, while keeping high frequency response, high detection sensitivity, and good signal quality thus stabilizing the output.

Title: Method and apparatus for cooling and supporting strand in plate casting mold of continuous casting installation
Inventor: YOSEFU SERAARU
IPC: B22D11/04
Filed: 1983-02-12
Abstract: During a change in casting parameters, particularly during displacement of a mold wall to change the strand format or cross-sectional shape, the supporting action and the cooling capacity should not fall either below a well-defined supporting action and a predetermined cooling capacity in order to avoid metal break-out or other defects in the cast strand. Furthermore, upon changing the strand cross-section the rate of adjustment should be increased in order to reduce the length of transitional pieces between the old strand format and the new strand format. To achieve this result it is contemplated to bend the mold wall, during displacement thereof into each pivotal position thereof, this bending of the mold wall corresponding to the instantaneous geometric shape of the moving solidified shell or skin of the strand and such bending is represented by bending lines.
