Title: Storage device
Inventor: FUJITA HIDEO
IPC: G06F11/10
Filed: 1980-09-02
Abstract: PURPOSE:To decrease the number of terminals, by making an error correcting circuit inactive during the diagnosis to enable a hard error of the storage part and sharing a signal line. CONSTITUTION:A CE signal having a level higher than a rated value is applied to a CE terminal druing the diagnosis. The level of a node 31 is decided by the threshold value of a transistor (TR) 36, and this level is lowered by a level lowering means 39 to be transmitted to a node 32. When a TR37 conducts, a node 33 is set at a low level with a TR38 cut off. Thus a node 34 is set at a high level. The high level of this node 34 is turned into an operation inhibition signal of an error correcting circuit.

Abstract: PURPOSE:To secure the high-temperature and steady stoichiometric state for the metal to be measured by cutting off the air current which is liable to mix into the frame formed on the photometric path, thus increasing the sensitivity for the atomic absorption (emission) analysis using the gas frame. CONSTITUTION:Glass 11 and 11 are stuck to face 10, where the optical path passes, of the noncombustible structure component which possesses opening part 8 at the bottom surface along with windbreak walls 9 and 9 provided at both sides. The device of such constitution is fixed by close adhesion onto the burner in such way that the slit of the burner may be positioned under part 8, and thus can be used for the atomic absorption (emission) analysis. In the case of the measurement outside the ultraviolet range which is affected by the light absorption via the glass, slits 12 and 12 are provided in place of glass 11 and 11. Thus the inactive gas is sprayed in a high speed through the slits to form the gas curtain which prevents the mixing of the air.

Title: Recorder and reproducer of magnetic sheet
Inventor: YASUNAGA AKIRA
IPC: G11B5/58
Filed: 1980-09-03
Abstract: PURPOSE:To increase the following performance of a magnetic head and to ensure the stable recording and reproducing, by providing an elastic member that energizes the magnetic head toward a magnetic sheet and thus negating the moment caused by the rubbing friction between the magnetic head and the magnetic sheet. CONSTITUTION:A magnetic head 2, when standing still, touches a magnetic sheet 1 with a coil spring 7. However, an attachment stand 3 is inclined due to a shift of position between a contact part 2a and the spring 7, and accordingly the inner wall of a sleeve 3d touches a guide shaft 4 at two points A and B to produce the side pressure. When the head 2 shifts toward an arrow (v) in the figure 7 in the recording/reproduction mode, the friction force F opposite to (v) is produced at a contact part between the part 2a and the sheet 1. As a result, an inclination of +theta is eliminated for the sleeve 3d, and the sleeve 3d is maintained nearly in parallel to the shaft 4. This eliminates the friction force produced at the points A and B.

Title: Cooling pipe cast-in casting steel product and its manufacture
Inventor: KURUSU NAOTOSHI
IPC: B22D19/00
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To prevent crack propagation to a pipe even though cracks or the like generate in a cast steel product main body by casting-in a cooling double pipe, having an aluminum diffusion coated layer applied a calorizing treatment to the inner surface of the inner pipe and the outer surface of the outer pipe, in the non-fused state. SOLUTION: The cooling double pipe 2 is composed of the concentric inner pipe 3 and outer pipe 4 and a cooling water is made to flow through the inner pipe 3. The aluminum diffused layer 5, 5' by the calorizing treatment are formed in the inner surface of the inner pipe 3 and the outer surface of the outer pipe 4, whereby the excellent high temperature oxidation resistance and corrosion resistance are provided in the cooling double pipe 2. Since the alumina coating by oxidation is formed on the outer surface of the aluminum diffusion coated layers 5, 5' to prevent the invasion of an oxygen atom, high temperature oxidation resistance is obtained. Since the alumina film has a high melting point and bad wettability with molten metal, it is not brought into contact with molten metal and cast-in in the non-fused state.  By this way, even though cracks generate in the cast steel product, crack propagation to the double pipe 2 is prevented, and water leakage and corrosion of the cast-in cooling double pipe 2 are prevented.
