Filed: 1988-10-26
Abstract: PURPOSE:To curtail the number of memories by dividing and storing data in an even address and an odd address of a storage means for storing the data of a prescribed bit, and outputting it as data of the number of bits of an integer multiple of the prescribed bit. CONSTITUTION:When an address designating signal is outputted from a CPU 1, data of a prescribed bit stored in an address indicated by the address designating signal is read out of a ROM 3 in which the data of the prescribed bit is stored and one set of data are stored by an address of continuous (n) addresses (n denotes an integer), and by interlocking with a variation of a clock signal, the lower digit part of the address designating signal is varied by FF circuits 6, 7 by (n)-1 times, and one set of data stored in the continuous (n) addresses are read out successively from the ROM 3. Subsequently, whenever the prescribed bit is read out of the ROM 3, data of continuous (n)-1 addresses are set to a latch circuit 9, and when data of an address continued from the address of this set data is read out, data of continuous (n) addresses are outputted simultaneously.

Title: Four wheel steering device for vehicle provided with safety device
Inventor: KANAZAWA HIROTAKA
IPC: B62D7/15
Filed: 1985-12-04
Abstract: PURPOSE:To prevent a vehicle from fluctuating when a failure occurs, by providing a means for blocking the communication between a hydraulic actuator and a control valve therefor when a fluid pressure system for a rear wheel steering mechanism fails. CONSTITUTION:When a hydraulic system fails, no oil flows through pipe lines 31, 17, and therefore, the pressures of pipe lines 33, 32 are made to be equal to each other. Accordingly, no axial force due to the pressure differential is effected across a spool 26a in a block valve 26, and therefore, the spool 26a may be moved by a spring 42. At this position the passages between pipe lines 28, 24 and between pipe lines 27, 25 are blocked, and hydraulic oil in a hydraulic actuator 23 is confined so that a piston 23d is made to be stationary. With this arrangement, even if the system is failed, the chambers in the hydraulic actuator 23 resist against the external force, sufficiently, and therefore, it is possible to restrain the vehicle from being fluctuated.

Title: Ceiling cornice structure
Inventor: KAMITE MASAYUKI
IPC: E04F19/04
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To improve the workability by providing a receiver material to be fixed to a wall surface and a ceiling cornice to be engaged with the receiver material so as to decorate a boundary between a ceiling surface and a wall surface. SOLUTION: A receiver material 10 is adhered to a wall surface 53 in the condition that a top surface of an abutment corner part 30 is made to abut on a ceiling surface 50, and while a nail is placed from inside of a room for fixation. The receiver material 10 is covered with a ceiling cornice main body 20 from the front surface of a main body side engagement part 13 so as to pinch the receiver material 10. The main body 20 is pushed to the receiver material 10, and an upper part 41 to be engaged is engaged with an upper engaging part 31, and a lower part 42 to be engaged is engaged with a lower engaging part 32. Since the receiver material 10 is covered with the main body 20, a nail head is left as it is exposed in the surface, and since a nail is not used in the main body 20, nail cover is unnecessary. Furthermore, the surface of the main body 20 made of the cellulose fine powder such as wooden powder is colored with the resin mixed with the powder, which carries the hard fine powders at a diameter smaller than that of the wooden powder, so as to form a wood pattern. Nail head can be thereby covered without a special process and a special curing tool.

Abstract: PURPOSE:To remarkably improve the reliability of the corrosion resistance of the title chemical heat accumulator and to prolong its service life by forming a copper ion elution preventing film on the surface of the building material of the accumulator consisting of copper or a copper alloy. CONSTITUTION:In the chemical heat accumulator using an aq. mixed soln. of highly corrosive CaCl2 and LiBr as accumulating medium, a copper ion elution preventing film is formed on the surface of the copper or copper alloy as the building material. An oxide film consisting essentially of Cu2O, the film of a compd. of copper and an org. corrosion inhibitor, or the two-layer film consisting of both films are preferably used as the film. The oxide film is formed by oxidizing the metal at 100-300 deg.C in a gaseous-phase atmosphere contg. >=1 kind among O2, O3, and H2O. Imidazole, etc., contg. at least N atom in the molecule is preferably used as the org. corrosion inhibitor.

Title: Recorder
Inventor: SASAKI YOSHIYUKI
IPC: G11B5/09
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption at recording time by driving plural current sources with output voltages different from each other and recording the input digital data according to the state of the input digital data. SOLUTION: A constant current source control circuit 101 monitors potential of a nodal point 107, and turns on a constant current source 102 when the potential of the nodal point 107 comes near to Vcc1 . Thus, the potential of the nodal point 107 becomes the voltage obtained by subtracting the voltage drop of the constant current source 102 from an output voltage Vcc2 of power source 11. A constant current source control circuit 106 also acts similarly, and it controls the potential of the nodal point 108 to the value obtained by subtracting the voltage drop of the constant current source 105 from the output voltage Vcc2 of the power source 11. The power source 11 supplies current in the period that the data are inverted, and the power source 12 supplies current in another period. In such a case, the main source 12 supplies the current required for recording. Since the potential of the nodal points 107, 108 are made higher than that of the power source 11, the output voltage Vcc1 of the power source 12 is lowered.
