Abstract: PURPOSE:To improve the performance of a protective film without causing adverse influence on magnetic characteristics and to obtain a hard magnetic disk with excellent corrosion resistance by forming a cobalt passive state film excellent in corrosion resistance on the surface of the hard magnetic disk of a ferromagnetic thin film type essentially comprising Co. CONSTITUTION:A NiP/Al disk is used as a nonmagnetic substrate, and the substrate is maintained at 300 deg.C, on which a Cr base layer is fast formed to 2,000Angstrom  thickness and then a Co-Ni layer is formed to 500Angstrom  thickness by sputtering with using a Co - 20wt.% Ni target. Thus, a disk of Co-Ni/Cr/NiP/Al is formed, and two of these disks are stuck and pressed together with a 10m thick polyethylene film interposed, allowed to stand as loaded for three days in an oxygen-rich atmosphere. The obtained hard magnetic disk comprises the substrate 1 of Cr/NiP/Al three-layered structure, the Co-Ni magnetic layer 2 deposited on the substrate and the Co passive state film 3 near the surface of the Co-Ni magnetic layer. Thereby, the protective layer with more effective corrosion resistance can be obtained.

Title: Hot water supplying apparatus
Inventor: KURAMOTO SHINJI
IPC: F24H1/14
Filed: 1983-03-09
Abstract: PURPOSE:To enable hot water to be supplied at a predetermined temperature even under a heavy load, by providing a water adjusting valve in a water passage, and controlling the water adjusting valve based on the difference between the predetermined temperature and the discharged hot water temperature at the time of maximum combustion, in a hot water supplying apparatus with a proportional combustion controller. CONSTITUTION:The discharging temperature of the hot water that has been heated in a heat exchanger 1 is detected by a temperature sensor 4. The detected temperature is compared with a predetermined temperature, and a motor and a proportional valve 6 are controlled by the output proportional to the thus obtained difference to control the quantity of combustion. Using as a reference the maximum capacity at which a blower 3 is at the maximum rotational frequency, the amount of heat of combustion is lowered when the combustion is carried out at or below the maximum capacity in such a way that the discharged hot water temperature is at the predetermined temperature, whereas the opening of the water adjusting valve 5 is throttled if the combustion is carried out above the maximum capacity. By controlling the water adjusting valve based on the difference in the discharged hot water temperature, hot water having a predetermined temperature can be obtained even if the load is increased.

Title: Photoelectric switch
Inventor: TANIGAWA KIYOSHI
IPC: G01V8/12
Filed: 1985-02-28
Abstract: PURPOSE:To generate no malfunction even in case when an amplifying circuit has been saturated, by detecting a fact that an output of the amplifying circuit has been deflected to the side opposite to an output of a photodetector during a timing clock, and clearing a counting circuit. CONSTITUTION:An output signal b1 of an amplifying circuit 6 is led to a comparator 12 to which a threshold value being lower than the potential of the time of no-signal of the amplifying circuit 6 has been set. The comparator 12 generates a signal h1, when the output b1 of the amplifying circuit 6 is deflected to negative and has drawn near the saturation, and clears a counter 50 by the same timing as the generation of a projecting pulse a1 through an AND gate 13, etc. That is to say, when the projecting pulse has been projected, it is detected that the output of the amplifying circuit 6 is deflected in reverse to the photodetecting output and has drawn near the saturation, and the previous counting value is cleared, therefore, wrong counting corresponding to a photodetecting signal which has been annihilated by the saturation of the amplifying circuit is prevented, and malfunction can be prevented.

Title: Register writing system
Inventor: MAKIURA YASUHIKO
IPC: G06F7/00
Filed: 1986-02-22
Abstract: PURPOSE:To reduce the burden of a program without increasing a scale of a hardware, by executing a write operation to a memory for holding an address in common, and executing simultaneously write to a register and the storage of a copy of the contents of the register to a memory. CONSTITUTION:A microprocessor 1 outputs desired data to a write data bus 101, and also outputs a specified address (i) to an address bus 102, and sets a memory write signal 201 to '1'. As a memory write signal 201 is '1', a memory 2 writes the data of the write data bus 101 to the designated address (i) by the address bus 102. On the other hand, a decoder 4 discriminates a fact that an address of the address bus 102 is the specified address (i). In this case, since the memory write signal 201 is '1', an AND gate 5 writes the data of the write data bus 101 to a register 3 simultaneously with the memory 2 by setting a register write signal 203 to '1'.

Title: Production of die for press blanking
Inventor: YAMADA TOYONOBU
IPC: B23K26/382
Filed: 1982-03-12
Abstract: PURPOSE:To produce a die for press blanking having excellent workability, less strain and high quality, by irradiating laser light to a material for dies to pierce an under hole, and machining the under hole with electric discharge thereby forming the hole for blanking. CONSTITUTION:When a nozzle 10 is moved under irradiation of laser light 9, a material 3 for dies is cut successively and an under hole 4 is opened. The cut part 1a is cooled quickly with cooling water 11a or the like after passage of the laser light 9, whereby the effect similar to the effect of a quenching treatment for hardening is obtd. Since the under hole 2 is machined by the laser, the hole is worked to optional shapes in conformity with the shapes of cutting edges, and is worked with extremely small margins in the stage of electric discharge machining, thus the cutting edge surface having high accuracy is obtained with less consumption of an electrode 12. The influence of heat is small in the parts except the parts to be cut by the laser light 9; therefore, the strain during the cutting is extremely little.

Title: Common bus control system
Inventor: MURAI MASAO
IPC: G06F15/167
Filed: 1985-02-27
Abstract: PURPOSE:To efficiently transfer data by reading and updating a pointer in a bus cycle which conducts buffer management. CONSTITUTION:In a system consisting of three units of CPU which constitute a multiprocessor, a common bus 4, and peripheral devices 5 such as a communi cation control device which carries out data transfer, two or more bus cycles are needed when a large amount of data is transferred from 1 to 5. If 2 transfers data to 5 in between a bus cycle and a bus cycle, the data from 1 and that from 2 will be mixed up in the buffer 5; therefore, such transfer must be prohibited. For this reason, in the case where data is to be transferred from 1 to 5, the pointer P, indicating the freeness of the transmission buffer, initially is read. At this time, p is updated to p+n (where, n is the size of the data which 1 is bout to transfer). 1 transfers the data to the position that p indicates. Where 2 transfers data to the same transfer buffer during 1 is transferring data, 2 reads p, obtaining p+n. In this case, p becomes p+n+m (where, m is the size of the data which 2 is about to transfer).
