Title: Shared disk device for magentic disk and magneto-optical disk
Inventor: GOTO YASUYUKI
IPC: G11B11/105
Filed: 1991-07-15
Abstract: PURPOSE:To apply a single recording/reproducing device to both a magnetic disk and a magneto-optical disk by resetting a spindle at a prescribed position and also actuating alternatively the corresponding heads in accordance with the type of a recording medium. CONSTITUTION:A spindle 15 which supports a recording medium is reciprocated by a shift mechanism between the positions A and B for a magnetic disk and a magneto-optical disk respectively. A detector decides the applied recording medium. Based on this deciding result, the spindle 15 is moved to the position A or B. At the same time, the corresponding magnetic disk head 21 and magneto-optical disk head 25 are alternatively selected by a control means and then actuated. Thus a single recording/reproducing disk device can be applied to both the magnetic disk and the magneto-optical disk.

Title: Method of manufacture shaft rotation device
Inventor: MATSUMOTO SHIYOUICHI
IPC: F16C3/00
Filed: 1980-12-09
Abstract: PURPOSE: To simply manufacture a shaft rotation device, by utilizing the center hole of a bearing with an inside rib, to mold a shaft from molten resin and support the shaft rotatably in the bearing because of a dimension difference resulting from the contraction of the resin.  
     CONSTITUTION: An annular rib 4b is provided on the inside of the center hole of a bearing 4. The bearing 4 is then set in a molding machine not shown in the drawing. Molten resin is poured into the center hole of the bearing 4 and solidified. As the molten resin is solidified as a shaft 5, the resin contracts so as to make a clearance 6 between the shaft 5 and the inside of the bearing 4 to support the shaft rotatably. Because of the presence of the rib 4b, the shaft 5 does not go out. The radial play of the shaft 6 is limited by the tapered surfaces 4b of the bearing 4. The axial play of the shaft 5 is limited by the tapered surface 4a and the rib 4b. According to this method, a shaft rotation device is easily manufactured.

Title: Light receiving device of single-lens reflex camera
Inventor: FUKUHARA TOORU
IPC: G03B13/36
Filed: 1982-10-04
Abstract: PURPOSE:To select a size of the zone on respective optimum focal surfaces for focus detection and exposure measurement, by providing a switching means which acts upon an object light in the light scattering mode in case of the photometric mode and acts upon it in the light non-scattering mode in case of the focus detection mode. CONSTITUTION:A light reflecting means E is constituted with a plane reflective mirror 6, two transparent electrodes 7a and 7b, and a liquid crystal layer 8. At the focus detection time, no voltage is applied across electrodes 7a and 7b. In this case, the liquid crystal layer 8 is transparent approximately, and the conjugate image of an image formed in an area AC on a film surface 2 is focused again onto a light receiving face of a photodetector 14 by a refocusing lens 13. At the exposure measurement time, a required voltage is applied across electrodes 7a and 7b, and the light scattering action is caused in the liquid crystal layer 8. Consequently, the light which passes a center P of the exit pupil of a photographing lens 1 and goes toward points B and D on the film surface 2 is scattered by the liquid crystal layer 8 and is led to the photodetector by the lens 13. Thus, the light in a range from the point B to the point D on the film surface 2 can be received at the exposure measurement time.

Filed: 1980-12-10
Abstract: PURPOSE:To obtain semitransparent mirror for a laser which has an inexpensive secondary laser light suppressing film and an output adjusting film, by providing a multilayered interference reflecting mirror on one surface of a transparent base as a mirror surface and an absorptive film on the other surface. CONSTITUTION:On the reverse side of a base 1, an absorptive film 22 is provided to attenuate various secondary beams T22 and T23 and T24 much more greatly than a primary beam T12 by absorption while relatively reducing the attenuation of the primary beam T12 due to absorption. Then, a film material is selected while attention to the thickness (d) and coefficient alpha of absorption is paid. Namely, the product alphad is set to about 5X10<-1> so as to obtain the intensity ratio of the secondary beam to the primary beam 1% less than that of a conventional laser semitransparent mirror having a reflection preventive film 21. Thus, an inexpensive, excellent-operability semitransparent mirror for a laser which has a secondary laser light suppressing film and an output adjusting film is obtained.

IPC: G06T1/00
Filed: 1995-06-15
Abstract: PURPOSE: To easily set a read position by providing a mark showing a read possible range at an appropriate position on the outer periphery of a casing. CONSTITUTION: The marks 3-4 showing the read range are put near a contact part with an original 2 in the lower end part of a scanner 1 in a vertical direction and a lateral direction. Thus, the user of the scanner 1 sets the scanner 1 on the read range 6 on the original 2 and makes the scanner 1 in a state where it is slightly lifted up from the original 2. Then, the marks 3-4 are compared with a range 5 whose reading is desired from the lateral direction. Thus, the scanner 1 can be set on the original 2 while confirming that the range 5 is settled in the read range 6. Thus, the read range 5 can satisfactorily be set in the range 6 at every reading.

Title: Readout address generating circuit for serial access memory
Inventor: KIMURA YASUYUKI
IPC: G11C8/04
Filed: 1994-07-26
Abstract: PURPOSE:To carry out normal high-speed readout operation by inputting outputs of plural logical gates to plural selection circuits as readout address signals. CONSTITUTION:A reset signal RST becomes an H by only the amount of one cycle of a clock RCLK. Then, when a next RCLK is risen after the RST is inputted, the output signal Q0 of an FF301 is risen to become the H. However, an AND 311 outputs the RC0 signal of an H level for the first time after the signal Q0 becomes the B and the RST is fallen to an L. In the rising of a next RCLK, the output signal Q1 of an FF 302 is risen to become the H and the signal Q0 is changed to the L, Consequently, the signal RC0 is changed to the L and the pulse width of this signal becomes the amount of one cycle of the RCLK. Moreover, the output signal RC1 of an AND gate 312 is risen after the signal Q0 becomes the L. Subsequently in the same way, the outputs of gates 312... are risen after the output of the FF of the front stage becomes the L and then signals RCO... are supplied to respective sense-amplifiers inserted into bit lines.

Then, after the second period which is a function of zero quantum modulation frequency of molecure of the metabolite, the third RF excitation magnetic field pulse is applied so that magnetization in the horizontal direction is restored.  The resulting echo NMR signal is corrected, and the above process is repeated with a series of different values for the second period, so that 2-dimension array is generated.

Abstract: PURPOSE:To enable the measurement of source potential, by a method wherein a DC voltage form is connected between a source electrode and a reference potential supply source and it is utilized that the potential of a channel becomes equal to that of a source when voltage equal to or less than channel potential and voltage equal to or more than said potential are applied in this order to a drain electrode. CONSTITUTION:Because channel potential phiCH is lower than source and drain potentials phiS, phiD at time t1 as shown by (a), charge is not moved. At time t2, because drain applied voltage VD comes to OV, charge is supplied from a drain region 14 as shown by (b) and the potentials phiS, phiD are equal and come to a value lower than the channel potential phiCH. At time t3, when the drain applied voltage VD comes to high positive voltage, phiD becomes high while charge is moved to the drain region 14 from a low source region 13 and phiS is also raised but, when phiS becomes equal to phiCH, the charge movement is stopped by phiCH as barrier to form potential distribution as shown by (c) and phiCH to gate applied voltage VG is displayed by a DC voltmeter 21 connected to the source electrode 13. As the result, the channel potential phiD can be known by the DC voltmeter 21.
