Title: Magnetic information reader
Inventor: FUKAZAWA KAZUO
IPC: G06K7/01
Filed: 1993-03-11
Abstract: PURPOSE:To respectively read the respective kinds of information from one data track of the same magnetic substance on different magnetic field conditions by using a track head provided with the two types of track head structure. CONSTITUTION:First and second core members 15 and 16 respectively provided with gaps 20 are parallelly installed through a shield 19. The respective gaps 20 are linearly arranged in the direction of an arrow A. Thus, magnetic information recorded in a card can be read along a direction orthogonal to the direction of the arrow A, and the same magnetic information can be read at the same time (timing) by the first and second core members 15 and 16. On the other hand, the magnetic field conditions of respectively correspondent first and second cores 15 and 16 are made different by controlling the electrification of first and second coils 17 and 18. As a result, the two kinds of different magnetic information can be provided from one data track of the magnetic card on the different magnetic field conditions.

Title: Run-length encoding device
Inventor: TOMITA SATORU
IPC: H04B14/04
Filed: 1984-03-14
Abstract: PURPOSE:To reduce the capacity of buffer memory for storing intermediate codes and also to reduce the cost of the device by providing the buffer memory between a code conversion part and an unfixed-length conversion part, and employing intermediate codes having word length which is short enough to determine an unfixed-length code words unequivocally. CONSTITUTION:Input data (a) is inputted by scanning lines from a data input part 21 and counted by an RL (run length) counting part 13 to output a binary RL value (b) of every run. This RL value (b) is code-converted immediately by a parallel code conversion part 22 on bit parallel basis into an intermediate code (c) with fixed length which determined an unfixed-length code (d) unequivocally, and the converted code is stored in the parallel code buffer 23 in sequence. When the output of the last bit and the input of the next intermediate code are performed at the unfixed-length conversion part 15 in the same operation step, the number of operation steps required from the unfixed-length conversion becomes equal to the word length of the unfixed-length code word. Therefore, any intermediate code with which the kind of the unfixed-length code word can be discriminated is usable. Further, this intermediate code does not have enough information for the generation of the unfixed-length code word, so its word length is short and the capacity of the parallel code buffer 23 may be small.

Title: Defect detector
Inventor: MINEGISHI SHINJI
IPC: G02B21/06
Filed: 1991-02-23
Abstract: PURPOSE:To detect non-destructively a defect of the surface of a semiconductor device by a method wherein lighting light is changed to generate a halation and the defect is detected. CONSTITUTION:As there is a possibility that the existence of a void causes disconnection, there is the need to detect the void as a defect. However, a crystal grain boundary can not be said to be a detect and is an ignorable defect, there are cases where a hillock can be also ignored and there are many cases where there is no need to detect the hillock as the defect. In such a case, it is suitable that a halation is generated to detect the defect. This reason is that if the halation is generated, an image, from which the hillock disappeared by the strength of halation, is obtained or an image, from which both the hillock and the crystal grain boundary disappeared, is obtained.

The components consists of a vitreous material, an uncombusted carbon and water and the content ratio of the vitreous material to the uncombusted carbon is different according to the particle diameter. Because a foamed body foamed by firing one different in the content of the uncombusted carbon under the same condition has different property according to the particle diameter though the chemical component of the vitreous material does not depend on the particle diameter, an excellent product free from foaming ununiformity as the whole and having low water absorption is obtained by firing under a suitable condition for every each fraction.  As the substantial degree of the classification, one fraction is setted so as to be held between 2 sieves, in which the ratio of the sieve opening is 2<2/4> to 2<6/4> . The max. particle diameter and the min. particle diameter are preferably setted respectively to 20-50 mm and 0.1-0.3 mm. The inorganic foamed body is useful as a lightweight aggregate.

Filed: 1991-03-15
Abstract: PURPOSE:To reduce the change of a relative speed between a rotary magnetic head and a magnetic tape at the time of switching the traveling speed of the magnetic tape and even at the time of the accompanying change of the number of rotations of the rotary magnetic head. CONSTITUTION:The traveling speed of the magnetic tape is compared with a reference traveling speed by a tape traveling servo circuit 24 and supplying and winding reel motors 13 and 17 are controlled so as to make them coincident. The number of rotations of the rotary magnetic head is compared with the reference number of rotations and a drum motor 4 is controlled so as to make them coincident. When a reference traveling speed is switched from a first reference traveling speed to a second reference traveling speed different from the first. the reference number of rotations of the rotary magnetic head is switched from the first reference number of rotations to the second reference number of rotations so that the relative speed between the rotary magnetic head and the magnetic tape is maintained constant in spite of the change of the reference traveling speed. Then, the switching from the reference number of rotations of the drum motor 4 to the second reference number of rotations is operated step by step by a specified number of rotations.

Title: Photographic film magazine
Inventor: YAMAGUCHI KEIJI
IPC: G03C3/00
Filed: 1985-03-14
Abstract: PURPOSE:To shorten an adhering stage and to make troublesome process control unnecessary by combining the body of a magazine with at least one adhesive layer of a hot-melt adhesive and an unsealed fabric for a light shielding member to form each of the inlet and outlet parts. CONSTITUTION:A rectangular metallic plate for the body of a magazine is heated, and light shielding members coated with a hot-melt adhesive are press- bonded to both ends of the late. The plate is then rounded, a film is charged, and capping is carried out to obtain a photographic film magazine. Since conventional two stages for sealing fabrics for light shielding members and adhering them to the body of a magazine is completed in one stage for coating the fabrics with the hot-melt adhesive, the number of stages can be reduced and an adhesive drying stage is not required. Since nearly instantaneous adhesion is carried out, the press bonding stage can be considerably shortened. Thus, stages and time are synthetically shortened.
