Title: Automatic listening position correction device
Inventor: YAMAGUCHI HIROYUKI
IPC: H04S1/00
Filed: 1993-09-03
Abstract: PURPOSE:To provide an automatic listening position correction device which automatically corrects the acoustic field unbalance caused by the range differences between each speaker and a listening position. CONSTITUTION:M series signals are reproduced by speakers 71, 72, 73 and 74. The responses are received by microphones 81 and 82 placed at a listening position and are stored in a prescribed memory. Then, the M series responses are restored into impulse responses by a high speed M series transformation. Then, a peak value of these impulse responses is searched and a threshold is set for the detection of rises based on the peak value. Then, the rising time, at which the threshold is exceeded first time, is detected. Lastly, make the speaker, which has a longest rising time among the speakers 71 to 74, as a reference, obtain the differences in rising times among the speakers 71 to 74 and set the respective differences as the output delays for the respective speakers 71 to 74.

Title: Exposing method and stepper
Inventor: OKUMURA MASAHIKO
IPC: G03F9/00
Filed: 1994-09-14
Abstract: PURPOSE: To improve the superposing accuracy by aligning the surface of a substrate with the focusing surface of an off-axis alignment system and detecting the position of an alignment mark on the substrate by aligning the alignment mark with the mark detecting position of the alignment system. CONSTITUTION: A photosensitive substrate W is placed on a Z-stage 17 and the position of an alignment mark for sample shot on the substrate W is detected with an alignment sensor 27. At the time of detecting the position of the alignment mark, a main control system 14 tilts a mirror 47 by the angle corresponding to the difference between best focusing positions through a driving section 51 so that the focus signal of an AF sensor can come to a zero-cross point on the focusing surface of the sensor 27. When an auto-focusing section is made to work by moving the substrate W to a point immediately below a projection optical system 16, the surface of the substrate W moves to the focusing surface 54 of the sensor 27. In such a state, the alignment mark is moved to a point immediately below the sensor 27 so that the sensor 27 can detect the alignment mark.

Title: Method for recording information recording master disk
Inventor: KASHIHARA TOSHIAKI
IPC: G11B7/125
Filed: 1985-10-02
Abstract: PURPOSE:To increase the width of a guide track compared with the width of an address information pit by changing the intensity distribution of incident light of a condenser lens by an optical element in response to the information signal and changing substantially the recording spot size on an information recording master disk. CONSTITUTION:When an address information pit 12 is recorded, only a recording spot 14a is produced. While recording spots 14a-14c are generated when a guide track 11 is recorded. Thus the recording width is changed by changing substantially the recording spot size on a recording master disk. Thus W1>W2 is secured between the width W1 of the truck 11 and the width W2 of the pit 12. Then the output of reproduction signal given from an address information part is maximum. As a result, the reproduction signal output sent from the guide track part increases the reproduction signal output produced from a recording pit 13.

Abstract: PROBLEM TO BE SOLVED: To prevent the rotary shaft of a door from deforming or breaking even upon repeated resetting of its drive mechanism for adjusting errors in the position of the door, by employing a step motor as the drive source of the door. SOLUTION: A drive mechanism 1 is adapted to turn a door 6 and a door lever 8 into which a rotary shaft 7 of the door 6 is inserted by bringing an engaging part 9 of a drive lever 5 journalled to a motor actuator 2 into engagement with a guide hole 10 in the door lever 8 and causing the engaging part 9 to press the circumference of the guide hole 10 while moving along it upon the turning motion of the drive lever 5. The drive mechanism 1 is provided at its case 2 with a stopper 12 for restricting the position of the drive lever 5. The stopper 12 is situated at a position to prevent the engaging part 9 of the drive lever 5 abutting on the stopper from contacting with the end of the guide hole 10. In resetting the drive mechanism, the stopper 12 is thus prevented from receiving load to thereby keep the door lever 8 from load acting thereto from the drive lever 5.

The cytochrome C is oriented to a high degree by using the LB films 3, by which the gamma-globulin can be efficiently attached thereto an therefore, the electric field to be applied to the gate is eventually increased. The sensor having high sensitivity is thus obtd.
