Title: Microprogram controller
Inventor: OGA SHINJI
IPC: G06F13/00
Filed: 1989-02-23
Abstract: PURPOSE:To prevent the destruction of a firmware program by attaining such a constitution where the writing of the write data is prevented to a control memory if the write data to the control memory detects the writing of the firmware program to a store area. CONSTITUTION:The upper limit address 51 of the firmware stored in a memory circuit 5 is held by a boundary register 10. Then the address 51 is compared with a write address by a comparator 11 when the control information is written into the circuit 5. When the writing of the control information to the circuit 5 is equal to the writing to a firmware store area based on the result of comparison of the comparator 11, the writing of the control information to the circuit 5 is prevented by an AND circuit 12. Thus it is possible to prevent the destruction of the firmware stored in the circuit 5 due to a malfunction of the firmware or the hardware just with addition of a small quantity of hardware.

Filed: 1986-02-28
Abstract: PURPOSE:To realize a large inductance by movably disposing a magnet having different poles joined together so as to be integrated in a magnetic space of a magnetic core. CONSTITUTION:The movable magnet 4 has the pair of magnets 4a, 4b with the respective different poles connected together so as to be integrated in the magnet side. A connecting surface 5 is supported by a resilient support member so as to coincide with the center of a intersecting direction in the space 3. When a sound current is conducted through a driving coil 2, on both end surfaces of the magnetic core 1 facing the space 3, the N, S magnetic poles appear alternately, thereby, the movable magnet 4 receives the attraction and repulsion and vibrates in the direction shown by an arrow A. When the diaphragm is connected to the movable magnet 4, it operates as a sound element. The magnet flux formed by the two magnets 4a, 4b sounding element. The magnet flux formed by the two magnets 4a, 4b constituting the movable magnet 4 is shortened on the end surface of the magnetic core 1, and directed to the connecting different poles, so that it does not pass through the cycle magnetic path of the magnetic core 1 interlinked with the coil 2. Accordingly, an unidirectional direct current magnetic flux passes through the magnetic core 1, a magnetic saturation is generated and the large inductance is obtained without deteriorating the inductance.

Abstract: PURPOSE:To correspond to the strain of a semiconductor substrate and improve mask superposing precision, by previously forming a plurality of alignment marks on a semiconductor substrate, measuring the distance between the marks, correcting the magnification of demagnification projection, and performing alignment exposure. CONSTITUTION:The image 2 of a first mask is transferred in order on a semiconductor substrate 1, and alignment marks 3 are formed at four corners in a shot. In the next mask alignment process, positions of the marks 3 in one shot range of the substrate 1 are firstly measured. Next, the distance l1 (original designed value) between the respective marks 3 at the time of forming the marks 3 (at the time of first mask alignment) and the distance l2 between marks at the time of second mask alignment are compared, thereby measuring expansion and contraction of the substrate 1. After the image magnification is corrected on the basis of the above results, alignment exposure is performed. Thereby the transfer of an image 4 expanded or contracted by the strain of the substrate 1 is enabled, and high superposing precision can be obtained. That is, the image can be accurately superposed so as to correspond with the expansion and contraction caused by strain of the substrate 1, and the superposing precision can be improved.

Title: Laminated sheet inspecting apparatus
Inventor: IDE KAZUYOSHI
IPC: G01J5/10
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To monitor the width of the adhesive in a laminated sheet. SOLUTION: Infrared cameras 3a, 3b measure the temperature distributions of both the ends of a laminated sheet 1. A CPU 7 combines the thermal imagery data stored in frame memories 6a, 6b, obtains the area of the high temperature area in the combined imagery, and compares it with a reference area value. In the sheet 1, the temperature of the part coated with adhesive is high, and a temperature difference takes place to the part without adhesive. On the imagery, a contrast for expressing the difference occurs, and it indicates the position where the adhesive exists on the high temperature area on the imagery. When a cutout occurs on the adhesive, the temperature of the part where the cutout occurs is lowered, and hence the area of the high temperature area is reduced. Thus, whether the adhesive has a predetermined with or not can be discriminated.
