Title: Method for connecting mutual coating films, and formation of sprayed coating film on jointed part of member
Inventor: YAMADA KATSUHIRO
IPC: C23C4/12
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To form, with certainty, a sprayed coating film on the top of a protective film by forming the end of a protective film into tiered state and then forming sprayed coating films to corresponding thicknesses, at the time of forming a sprayed coating adjacently to a protective film on the surface of a member. SOLUTION: For example, mutual boiler tubes 1, where a protective film 2 is previously formed and a welded joint 3 is free from the protective film 2, are connected with each other, and then, a sprayed coating film 4 is formed by thermal spraying as a protective film for the part in the vicinity of the welded joint 3. At this time, the end of the protective film 2 is formed into tiered state by means of masking or etching. Then, sprayed coating films 4a to 4d are formed to respective thicknesses corresponding to respective thicknesses of the tiered parts 2a to 2d. By this method, the contact part with the end of the protective film 2 is free from voids because the thickness of the sprayed coating film 4a, formed first, is a small fraction, and also no unconnected part is left because the thickness of the sprayed coating film 4d as the final layer is small similarly.  As a result, the sprayed coating film 4 can be sufficiently formed on the top of the protective film 2.

Title: Magnetic recording and reproducing device
Inventor: SAITO FUMINARI
IPC: G11B15/04
Filed: 1986-10-13
Abstract: PURPOSE:To miniaturize a device, by disabling a recording operation when a means which detects the presence/absence of the projecting part, or the hole part of a part to be detected, is supported, and a holding means capable of being loaded/unloaded on a box body in which a tape cassette is housed, is removed from the box body. CONSTITUTION:When the tape cassette 3 is loaded, infrared light projected from a light emitting element 1, after arriving at an erroneous erasure preventing lug 4 through a first convergent lens 2, is reflected, and is made incident on a light receiving element 6 through a second convergent lens 5. When it is reflected on the erroneous erasure preventing lug 4, an electrical signal outputted from the light receiving element 6 is set so as to be stronger, and when the lug 4 is notched, an incident position on the surface of the light receiving element 6 is varied, then, the electrical signal from the light receiving element 6 becomes weaker. And when the electrical signal is strong, an electrical signal detector 8 detects it, and closes an erasing head circuit 9, and when it is weak, no signal is detected, then, the erasing head circuit 9 is opened, and erroneous erasure is prevented from occurring, and no current is permitted to flow on an erasing head when a holding part 10 is removed. In such a way, it is possible to surely prevent the erroneous erasure from occurring, and to miniaturize and make a magnetic recording and reproducing device light.

Title: Contact electrifying device
Inventor: OKUDA KOICHI
IPC: G03G15/02
Filed: 1989-09-19
Abstract: PURPOSE:To prevent the occurrence of irregular electrification and to perform electrification always stably and uniformly by coating a surface, where an electrifying member is brought into contact with the surface of a body to be electrified, with powder. CONSTITUTION:The electrifying member 2 is coated in such a way that the powder 4 is sprinkled on the electrifying member 2 or the member 2 is coated with powder dispersing liquid and then it is dried. Therefore, the coefficient of the friction of the electrifying member 2 against the surface of a body 1 to be electrified is reduced because of the sliding of the coating powder; even when the electrifying member 2 of low hardness is used to make it sufficiently adhere to the surface of the body 1 without partial looseness, the coefficient of the friction of the electrifying member 2 against the surface of the body 1 is always kept low. Since the occurrence of irregular electrification is prevented, electrification is stably and uniformly performed.

Title: Data transmission method
Inventor: HIROO AKIRA
IPC: H04L1/00
Filed: 1984-11-16
Abstract: PURPOSE:To prevent surely a miscorrection without decreasing information bits by adding a vertical parity bit to the data which correct an even number of errors after adding a redundant bit to the information bits converted into blocks. CONSTITUTION:A redundant bit 2 or 8 bits is added to an information bit 1 of 7 bits together with a vertical parity bit 3. Thus the code length of 16 bits, an information bit 7 and a correction capacity bit 2 are obtained. The data are transmitted with BCH (16, 7, 2) codes of a structure having an inter-code distance 6. In other words, the information bit Q(x) is divided by a polynomial G(x) to obtain the residual R(x) equal to a redundant bit 2. Then a vertical parity 3 shown by P=Q(x).X<8>+R(x) is added to the bit 2 for transmission. At the reception side the vertical parity P is divided by the polynomial G(x) to obtain a syndrome for correction of errors up to 2 bits. When an error of >=3 bits is decided, the bit Q(x) is applied as data without giving any correction.

Title: Automatic type safety chair and safety belt exclusive for automobile
Inventor: JESADANONT MONGKOL
IPC: B60R22/14
Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To provide a belt for securing safety of a passenger. SOLUTION: When collision is caused, since an iron bar 214A moves forward according to a predetermined distance 1, a key 235 can be removed. The upper tip of the iron bar and a seat back are brought down so as to turn up just backward by a spring 321 fixed between a lower part of the iron bar and a sheet metal 300 under a cushion. A passenger is prevented from colliding with a part in a car. A band safety belt reduces tensile force per area of the safety belt to the passenger to whom the belt is fastened. In a rear safety chair, a spur exists in a rear part of the iron bar to support a plate under a subdivided upper back panel.  Since the plate under the upper back panel is folded back downward by a fixed torsion spring when the iron bar moves forward by collision, a clearance in which the iron bar falls down by turning up backward together with the seat back is generated in respective parts of respective seats.
