Title: Diffusion furnace apparatus
Inventor: SASAHARA KATSUYUKI
IPC: H01L21/31
Filed: 1986-07-29
Abstract: PURPOSE:To prevent dusts due to a friction between the wheels of a mother boat and the wall of a furnace core tube from being generated to improve the yield of a diffusing furnace apparatus at the time of exhaust and intake of the dusts through the boat by providing wheel covers on the wheels of the boat. CONSTITUTION:Many semiconductor substrates 4 to be processed are aligned at a predetermined interval perpendicularly on a base 1 supported by wheels 2. Wheel covers 3 are attached to the peripheries of the wheels 2. The covers are wound up when the wheels are rotated to prevent dusts to be scattered from being adhered to a semiconductor substrate (wafer). Thus, the dusts generated by the friction are eliminated to be adhered to the substrate by the windup of the dusts by the wheels to improve the yield of a diffusing furnace apparatus.

IPC: G11B7/09
Filed: 1989-07-11
Abstract: PURPOSE:To securely perform a focus error adjustment by comparing a sum of output signals of 1st and 3rd photodetectors with a sum of output signals of 2nd and 4th photodetectors. CONSTITUTION:A diffraction element 13 is divided into 1st and 2nd areas 13a and 13b, forming a spot on the 3rd photodetector 20c out of focus error detecting light diffracted by the 1st area 13a at the time of generating no focus errors and focused in front of a photodetector 20 and then inverted. On the other hand, detecting light diffracted by the 2nd area 13b is set to form a spot in approximately the same size as the spot of the 3rd photodetector 20c on the 2nd photodetector 20b without inversion in front of the photodetector 20. Then, a focus error is detected by comparing the sum of the output signals of the 1st and 3rd photodetectors 20a and 20c with the sum of the output signals of the 2nd and 4th photodetectors 20b and 20d. By this method, the focus error adjustment securely is performed, and the manufacturing cost is reduced by decreasing the occupied area of the photodetector.

IPC: B41J29/22
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To readily determine whether or not a certificate stamp, which is issued when the electric power is broken down during the printing operation and the electric power is supplied again, is valid. SOLUTION: This certificate stamp issuing machine comprises an in-printing time power break-down memory means 13, a counting means 16, a printing line memory means 13, a power bleak-down judging means 11, 12, a printing condition judging means 11, 12 and a control means 11, 12. The judgment is made whether or not the printing is performed until a position whereby the printed result can be used as a certificate stamp in accordance with printed lines at a time when the electric power is break down during the printing operation. After the electric power is supplied again, an operation for making the printed result valid or invalid is executed based on the judgment result. When the operation for making it invalid is executed, the counting number of issued pieces of the certificate stamps is decreased and when the operation for making it valid is executed, the counting number is increased. The invalidating operation is executed such that a part of a roll paper, which is judged that printing is not performed to a position whereby it can be used as a certificate stamp (postage stamp) by the printing condition judging means 11, 12, is cut by a cutter.

Title: Method for rearranging roll
Inventor: HIRAMATSU TERUO
IPC: B21B39/08
Filed: 1982-10-15
Abstract: PURPOSE:To rearrange rolls of a required stand without stopping the running of a continuous rolling mill by shifting work rolls in the axial direction when a gap between the upper and lower work rolls of each stand of the mill is widened. CONSTITUTION:Each pair of pinch rolls 40 is kept in a released state during normal running; the gaps of upper and lower backup rolls and work rolls 21, 22 and 11, 12 are widened and each pair of pinch rolls 40 is actuated to pinch a material 10 when the rolls of (Sn)th stand are rearranged. Next, the rolls 11, 12 are taken out in the axial direction, and then a material supporting mechanism 50 is actuated to bring rolls 52 into contact with the material 10. In case of using a construction which raises the roll 11 only, the material 10 is kept out of contact with the roll 12 by raising the rolls 40 while keeping the pinched material 10 as it is. In this manner, the roll rearrangement of other stands is performed in sequence after completing the roll rearrangement of the (Sn)th stand.

Title: Liquid crystal display device
Inventor: OWADA JUNICHI
IPC: G02F1/1368
Filed: 1992-07-08
Abstract: PURPOSE:To prevent the generation of a horizontal stripe appearing on a screen of liquid crystal display panel by allowing a turn-on frequency of a back light, and a horizontal synchronizing frequency of the liquid crystal display panel to have a specific difference. CONSTITUTION:As for generation of a horizontal stripe, the horizontal stripe appears most remarkably on a screen in the case of a halftone display of a display state of C. Also, with regard to a state of generation of the horizontal stripe, the larger a difference DELTAf between a turn-on frequency of a cold cathode fluorescent tube of a back light and a horizontal synchronizing frequency of a liquid crystal display panel becomes, the smaller intensity DELTA Bp of the horizontal stripe becomes, and when this difference DELTAf is >=4kHz, the horizontal stripe becomes invisible. That is, when the turn-on frequency of a back light and the horizontal synchronizing frequency of the liquid crystal display panel are allowed to have a difference of >= about 4kHz, an interference effect of flickering (strength/weakness of luminance of high frequency) of the back light and flickering of the liquid crystal display panel can be eliminated, and generation of the horizontal stripe can be suppressed.

IPC: G11B11/105
Filed: 1984-08-31
Abstract: PURPOSE:To reproduce easily an accurate information signal when a recording medium is replaced, by controlling a bias magnetic field on a basis of a signal which detects the duty cycle of a reproduced signal. CONSTITUTION:A modulator 2 modulates a laser beam when information is recorded on a disc 9; and when the bias is adjusted, the modulator 2 modulates the laser beam so that the duty cycle is 50% to prevent the distortion of the reproduced signal. When information is recorded on the disc 9 at 50% duty cycle, the pit shape on the disc 9 is changed by the intensity of the bias magnetic field. An output proportional to the intensity of the magnetic field is obtained in a comparator 6 by this change, and this output is used to set automatically a proper bias magnetic field intensity.
