Title: Flaw detecting servo device
Inventor: NAKAJIMA YOSHIHIDE
IPC: G11B7/004
Filed: 1990-11-27
Abstract: PURPOSE:To made a servo operation not easily failed due to a flaw on a recording medium by providing a means to apply the beam preceding to a main beam for reading the data and a means to decide the flaw on the recording medium from the amplitude ratio of intensity signals by this preceding beam and by the main beam, and so on. CONSTITUTION:By moving the recording medium 101, the main beam 102 and preceding beam 103 are scanned on a target track keeping the positional relation each other to read out the data on the recording medium 101. In the period the preceding beam 103 passes through the flaw part, the amplitude of intensity signal for preceding beam is decreased since the reflected light is weakened by the scattering, the ratio of the amplitude of intensity signal for preceding beam to the amplitude of intensity signal for main beam becomes less than 1. This state is detected by an amplitude comparator 108 to decide whether the preceding beam 103 is just passing through the scratched part on the recording medium 101. By this procedure, the gain of a high frequency region of servo system is reduced beforehand, then a sensitivity of servo to the flaw is reduced, therefore, the operation is allowed not to easily follow to the scratch.

Title: Pattern display device
Inventor: MIWA MINORU
IPC: A63F7/02
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To prevent the erroneous detection of dust or the like accumulated at the joint of a display belt in a pattern display device for using the display belt and a photosensor. SOLUTION: When the display belt 22 is turned, a brush wipes the display belt 22 and it is possible that the dust or the like removed by the brush is accumulated at the joint 22a of the display belt 22 and forms a stain H. However, since an original point mark 50 itself is originally light-shieldable, a light shielding property is not lost even when the stain H is stuck to the joint 22a, and thus, problems are not generated at all for detecting the original point mark 50 by the photosensor. Also, the photosensor does not malfunction.

The porous minute spheres can control the permeation of the leuco dye contained therein, according to the quantity of thermal energy applied thereto. When heat sensitive elements 11 of a thermal head are heated to temperatures T1, T2, T3 (T1<T2<T3) according to an image signal from a CRT or the like, the leuco dye is released from the minute spheres 4 of the thermosensitive material 1 accordingly, and reacts with the color developer 7 on a recording sheet 8, resulting in color development, whereby a transferred image with continuous gradations is recorded. The porous minute spheres may be polystyrene or acrylic minute spheres.

Abstract: PURPOSE:To make it possible to manufacture a motor highly accurately at a low cost by positioning and laminating a plurality of thin plates, which are formed in conformity with the profile of a cross-sectional plane, thereby forming yoke plates, and providing a film comprising corrosion resisting material on the outer surface of the yoke. CONSTITUTION:When a yoke plate 5 of an outer yoke 1 is manufactured, a thin soft steel plate is punched and molded with a punch die set into a planar profile shape corresponding to the profile shape of a cross-sectional plane. Then, a bonding agent is applied on the surface. A specified number of the plates are laminated. Thus, the yoke 1 comprising yoke plates 5 having the specified size is formed. After the lamination and assembling, epoxy resin is applied on the outer surface of the outer yoke 1, and a film is formed. A thin film is punched and molded into the planar profile shape corresponding to the profile shape of the cross-sectional plane of a yoke plate 9 of an inner yoke 6 by the same way. After the lamination, the plates are fixed on a substrate 8, and the inner yoke 6 is formed. As a result, the yoke plates of the outer yoke and/or the inner yoke can be formed only by the punching and lamination. Since machining can be omitted, high precision is obtained at low cost.

IPC: H01L21/68
Filed: 1995-11-23
Abstract: PROBLEM TO BE SOLVED: To maintain the quality of semiconductor substrates constant even when a lot with a limited shelf time is mixed in other lots by computing, on the basis of a second predetermined feed time and a predetermined processing time of a second processor, estimated processing start and end times of first and second processors for each processing lot so that the shelf times of the lots is below a limit. SOLUTION: A processing-condition determining means 7 determines processing conditions of an identical type of lots to be scheduled to reach a processor 15 depending on the lot type. When it is desired to perform start-job reservation, a start job reserving means 5 computes, on the basis of the processing conditions of the processor 15 determined by the decision means 7, estimated processing start and end times for the lots, and writes them in a start job reservation representation memory 4 as reservation information. When the lots scheduled to be fed in are required to be subjected to continuous processing with a limited shelf time, the controller detects an idle time of the target processor from the reservation information of the memory 4, and determines the processing conditions of the processor 15 according to the fed-in lot type.

Title: Automatic judgment circuit for pulse width
Inventor: YAMAGUCHI HISASHI
IPC: G01R29/02
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to judge pulse widths in many channels in parallel, at high speed and at low costs by a method wherein, when the number of connected fundamental clock signals exceeds an upper-limit value or does not exceed a lower-limit value, an output is inverted so as to be held. SOLUTION: In an upper-limit judgment circuit at an upper-limit and lower- limit judgment circuit 5, when all BORROW signals in an upper-limit-value counter circuit 3 are at L, they are judged to be N.G. at an OR1 output the inverse of L, at a NAND8 output the inverse of H and at an INV7 output L. That is to say, when the number of counted fundamental clock signals exceeds upper-limit values at a PC1 to a PC3, the signals are judged to be N.G., and a CLER1 holds a result until a reset signal is input. On the other hand, in a lower-limit-value judgment circuit, when even one BORROW signal in a lower-limit-value counter circuit 4 is at H, outputs of FF's (NAND13, NAND14) are inverted at an OR2 output the inverse of H, at a NAND10 output the inverse of H and at a NAND output L, and, when the signal is at L, it is judged to be N.G. at an INV8 output.  That is to say, when the number of fundamental clock signals does not exceeds a lower-limit value at a PC4 to a PC6, a CLER2 holds a result until the reset signal is input.
