Title: Optical information reproducing device
Inventor: SHIMOO SHIGERU
IPC: G11B20/10
Filed: 1984-11-14
Abstract: PURPOSE:To eliminate the adverse influence of variation in DC level by reproducing recorded information from the output of a pulse generating circuit which compares the output of a wide band amplifier with a constant reference level and generates pulses. CONSTITUTION:A level shifting circuit 23 receives a wide-band readout signal 102 and a data area signal 104 and compares the DC level of the wide-band readout signal 102 with the constant reference value VR1 when the data area signal is off to generate a level shift signal 105 which varies the DC level of the output of the wide-band amplifier 20 so that its deviation is corrected. When the data area signal 104 turns on, the level shifting circuit 23 stops comparison of the DC level of the wide-band readout signal and holds the value of the level shift signal 105 right before the data area signal 104 turns on. Namely, the level shifting circuit 23 corrects the output of the wide-band amplifier 20 so that the DC level of the wide-band readout signal 102 becomes equal to the constant reference value every time the data area signal 104 turns off, thereby suppressing variation in the DC level of the wide-band readout signal 102 due to variation in the reflection factor of a record carrier 7, etc.

Title: Eddy-current flaw detecting probe
Inventor: ABE TAKESHI
IPC: G01N27/90
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To provide an eddy-current flaw detecting probe whose structure is simple, which can be made at low costs and whose detecting sensitivity is high. SOLUTION: This eddy-current flaw detecting probe which is provided has a structure wherein a board 4 which is provided with interconnections is connected to a cable 4 and a coil which radiates a magnetic field is formed. Consequently, the eddy-current flaw detecting probe whose structure is simple can be made at low costs. In addition, when the interconnections at the board 4 and interconnections at the cable 6 are connected so as to be deviated one by one, a tangential coil by which a magnetic flux reaches a comparatively deep position from the surface of an object to be inspected can be made simply. As a result, it is possible to provide the eddy-current flaw detecting probe whose detecting sensitivity is high.

Title: Data input method
Inventor: UEDA TETSUO
IPC: G06F3/02
Filed: 1990-09-11
Abstract: PURPOSE:To reduce the labor required for inputting data by automatically registering a code or number to be used when the code or number is not on a registration table. CONSTITUTION:When an input notice (interruption) is made from an input device 2, an input waiting status is canceled and whether or not the input is an ordinary one-character input is discriminated. When the input is the one- character input, the inputted one character is added to an input buffer 6 which stores a character string inputted before the one character is inputted. Then whether or not the inputting process of the one character is completed is discriminated. When it is discriminated that the inputting process is completed, the character string in the buffer 6 is registered on a registration table 7 and the input is terminated. When it is discriminated that the input process is not completed yet, the table 7 are retrieved for the data having a leading section coincident with the character string in the buffer 6. When such data is not present on the table 7, the input waiting status is again set. When such data can be obtained from the table 7, the obtained data are stored in a memory and displayed on a display device 3.

Title: Main spindle stop positioning device
Inventor: SUGIMURA YOICHI
IPC: B23Q15/26
Filed: 1990-09-11
Abstract: PURPOSE:To perform the stop position positioning control of a main spindle with simple structure by counting the pulses of a rotary encoder by the output of a position detecting sensor so as to output the stop signal of a motor, and discriminating the stop of the main spindle within a tolerance range also by the signal of the position detecting sensor. CONSTITUTION:A second shaft 2 is rotated by the driving of a control motor 8, and the torque is transmitted to a main spindle 1 through gears 3, 4. While a disk 5 is rotated together with the main spindle 1, a position detecting sensor 7 counts the frequency of detecting a detected body 6 and starts the counting of the pulse signals of a rotary encoder 10 at the time of detecting the detected body 6 at the second time. When the pulse signals are integrated and reach the set count D, a stop signal is sent to the control motor 8. Braking mechanism is thereby operated to stop the control motor 8 and therefore to stop the second shaft 2. When there is a detection signal on the detected body 6 from the position detecting sensor 7 in a turning angle position at the time of the main spindle 1 being stopped, the main spindle 1 is judged to be stopped within the specified tolerance range, and thus the positioning control of the main spindle l is completed.

Inventor: KITABAYASHI TADASHI
IPC: H04R7/12
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To make the frequency characteristic of a middle area, a distortion characteristic and the frequency characteristic of a high area compatible by making equal the front, rear, left and right cone surface radii for the center line of a cone-shaped diaphragm and making different the curvatures of the front and rear and the left and right sides. SOLUTION: The radii on the front, rear, left and right sides for the center line of a cone- shaped diaphragm 9A are the same, the curvatures R2 on the front and rear sides are made the same, the curvatures R3 on the left and right sides are made the same, and the curvatures R2 on the front and back sides and the curvatures R3 on the left and right sides are made different. By reducing the curvatures R2 on the front and rear sides, the high area of the frequency characteristic is flattened or extended, the degree affecting the frequency characteristics of a middle area and a distortion characteristic is reduced because the area with small curvature is reduced for all the areas of the diaphragm 9A, and the disturbance of the frequency characteristic and higher harmonic distortion are reduced.  Because the curvatures R3 on the left and right sides are large, the disturbance of the frequency characteristic of the middle area and the higher harmonic distortion can be reduced, and the influence affecting the frequency characteristic of the high area can be reduced because the area with large curvature is reduced for all the areas of the diaphragm 9A.

Title: Method and apparatus for controlling end face shape of molten metal
Inventor: NAKATO SAN
IPC: B22D11/06
Filed: 1985-10-30
Abstract: PURPOSE:To improve the quality of the shape at product ends by impressing DC current between rolls and acting DC magnetic fluxes perpendicularly to the DC current. CONSTITUTION:Electrodes 9, 9' which slide on the surfaces of the cooling rolls 4, 4' having electrical conductivity are provided and a pair of DC magnetic flux generators such as magnets 8, 8' are disposed near the ends in the space between the rolls 4 and 4'. The DC current is impressed between the rolls 4 and 4' by such mechanism; in addition, the DC magnetic fluxes can be acted near the roll ends perpendicularly to the DC current and in the opposite directions. Electromagnetic force, therefore, acts toward the inside in the axial direction of the rolls to hold the molten metal tending to leak from the ends of the rolls 4, 4', thereby trimming the shape at the ends of the molten metal. The quality of the shape at the product ends is improved by the above- mentioned method.

IPC: G06F3/0338
Filed: 1993-09-28
Abstract: PURPOSE:To reduce the size of a pointing device and improve the operability by controlling a cursor with the output pulse voltage of an amorphous magnetic wire. CONSTITUTION:An electromagnet 6 is incorporated in a cup 7 and amorphous magnetic wires 18 are put laterally in four grooves 19b of a wire holder 19. When an AC current of frequency fo is applied to the electromagnetic 6, the amorphous magnetic wires 18 are excited with the external AC magnetic field of the electromagnet 6 to generate pulse voltages of doubled frequency 2fo by Matteuci effect. A stick 2 is operated and then the distances between the amorphous magnetic wires 18 and electromagnet 6 vary, so that the influence of the AC magnetic field of the electromagnet 6 on the amorphous magnetic wires 18 becomes different as the distances vary. Consequently, the pulse voltages of frequency 2fo generated by the amorphous magnetic wires 18 vary. For the purpose, the cursor, etc., is controlled on the screen of a computer with the pulse voltages.

Title: Cleaning nethod for silicon substrate surface
Inventor: SUGII TOSHIHIRO
IPC: H01L21/3065
Filed: 1988-09-27
Abstract: PURPOSE:To suppress diffusion of impurity and pollution by forming atomic hydrogen through bringing hydrogen gas in contact with a filament and by removing a silicon oxide film coated on the substrate surface using the atomic hydrogen. CONSTITUTION:An Si substrate 2 is heated to 800 deg.C by a substrate heater 4, and a current is supplied to a tungsten filament 5 from a power supply 6, and the temperature of the filament is set at 2000 deg.C. Then, H2 is introduced into a vacuum vessel 1 through an H2 introduction tube at a flow rate of about 0.1cc/min. In case where the filament temperature is at 2000 deg.C, about 0.1% of molecular hydrogen is thermally dissociated into atomic hydrogen. Therefore, in this case, hydrogen atoms are formed at 5.4X10<15>/sec. If the pressure in the vacuum vessel 1 is kept at the order of 10<-5>Torr, the mean free path of the residual hydrogen is about 5m, so that the formed atomic hydrogens can reach the surface of the Si substrate 2 without even one collision. Thus, SiO2 is removed from the surface of the Si substrate 2 and the surface is cleaned.

Title: Road surface friction coefficient estimating device for vehicle
Inventor: KOGURE MASARU
IPC: B62D6/00
Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To prevent accuracy of estimation of a road surface friction coefficient from decreasing resulting from a time-lag difference between an actual value and a reference value with respect to driver's operation when the actual value of the motion condition of a vehicle is compared with the reference value for the estimation of the road surface friction coefficient. SOLUTION: An actual value estimating part 13 computes an actual value of a yaw rate by means of an observer, and a high friction coefficient road reference value estimating part 11 and a low friction coefficient road reference value estimating part 12 compute a high friction coefficient road reference value of the yaw rate and a low friction coefficient road reference value thereof, respectively, by means of a vehicle motion model. A yaw rate comparative road surface friction coefficient estimating part 14 compares the actual value with the reference values to estimate a road surface friction coefficient.  The estimating part 14 estimates the road surface friction coefficient only when the yaw rate rises, so that the estimated road surface friction coefficient value of good accuracy can be obtained without being affected by a time-lag difference between the actual value of the yaw rate and the reference value thereof with respect to driver's operation.

Inventor: KUBOTA SHINJI
IPC: H01Q9/06
Filed: 1985-10-29
Abstract: PURPOSE:To attain tuning to a lower frequency band or plural frequency bands without increasing the size by providing a rod where a conductor is placed in spiral or on a hollow rod insulator so as to act it like a loading coil. CONSTITUTION:A counter 8 is plated on the surface of an insulator 9 of the loading rod 4 and the conductor 8 is exfoliated in spiral by the method of etching to form a coil. Further, the conductor 8 is coupled electrically with rods 3, 5 by the contact and since the frequency band is low at the VHF band of a TV broadcast, the rods 3, 5, 5, 6 and 4 act like an antenna. Since the frequency band is high in the UHF band, the rods 2, 3 are disconnected electrically by the rod 4 and only the rods 5, 6 act like an antenna. In providing the conductor 8 in spiral, the coils act like the loading coil, the size of the antenna is not increased and the tuning to a low frequency band or plural frequency bands is attained.
