Title: Method of erasing information of wavelength multiplex recording medium
Inventor: TAMURA SHINICHIRO
IPC: G11B7/24035
Filed: 1988-05-16
Abstract: PURPOSE:To enable information erasing without lowering the space density of the wavelength multiplex recording medium and without allowing traces of thermal deformation, etc., to remain on the recording medium by irradiating the recording medium with the light of the wavelength region shorter than the wavelength region of the longest wavelength absorption band of a photosensitive material, thereby erasing the multiplex-recorded information. CONSTITUTION:The information multiplex-recorded on the wavelength multiplex recording medium on which is formed by dispersing the photosensitive material into a dispersion medium and on which the information is multiplex-recorded in the longest wavelength absorption band of the photosensitive material by optochemical hole burning is erased by irradiating said recording medium with the light of the wavelength region shorter than the longest wavelength absorption band of said photosensitive material. The photosensitive material is exemplified by a porphine photosensitive material, chlorine photosensitive material, phthalocyanine photosensitive material, quinizarin photosensitive material, tetrazine photosensitive material, etc. A good result is obtd. particularly when the photosensitive material is a tetraphenyl porphine material. The information erasure without lowering the space density of the wavelength multiplex recording medium and without allowing the traces of the thermal deformation, etc., to remain on the recording medium is thereby enabled.

Title: Control amplifier
Inventor: SATO HARUJI
IPC: G01S7/52
Filed: 1986-05-21
Abstract: PURPOSE:To improve the S/N of a waveform observed on a CRT by adding a series resistor to each emitter of transistors (TRs) constituting a differential amplifier and using a PN junction between the base and emitter of the TR as a load impedance. CONSTITUTION:One terminal of the 1st and 2nd resistors RA1, RA2 is connected respectively to the emitter of the 1st and 2nd TRs l, 2 and the PN junctin of TRs 4, 5 is used as the load impedance. Thus, the dynamic range of an input signal eA is increased by using the 1st and 2nd resistors RA1, RA2. Further, the resistance of the PN junction being the load impedance is varied attended with the change in a current 1c. Thus, the gain after a control amplifier CA is lowered more than a conventional value, and then the noise on a cathode ray tune CRT generated independently of the setting of an attenuator is lowered to be negligibly small.

Title: Superhigh strength steel
Inventor: FUKUI SHIYOUICHI
IPC: C22C38/00
Filed: 1980-08-27
Abstract: PURPOSE: To provide sufficient toughness and ductility as well as high strength to a steel by adjusting the S content to a very small amount to reduce the amount of unfavorable inclusions and by adding Ca to form a spheroidal composite inclusion of oxide and sulfide.  
     CONSTITUTION: This superhigh strength steel consists of, by wt., 0.25W0.55% C, 0.15W3.00% Si, 0.35W1.00% Mn, ≤0.005% S, 0.60W1.20% Cr, 0.15W1.20% Mo, 0.001W0.01% Ca and the balance Fe with inevitable impurities. When the S content exceeds the upper limit, no sufficient effect is produced by Ca for improving the toughness and ductility. Ca forms oxysulfide, the oxysulfide floats and separates during casting and remelting preferably in a vacuum, and the residual inclusion is spheroidized after the remelting. Below the lower limit of Ca produces no effect, and above the upper limit of Ca increases the amount of inclusions and deteriorates the toughness and ductility. To said basic components may be suitably added one or more among Ni, B, Ti, Nb and V.

Title: Production of high chromium roll having cavity on core part
Inventor: NAKAMURA SHIROU
IPC: B21B27/00
Filed: 1979-09-11
Abstract: PURPOSE:To improve the toughness of a high-chromium roll having a cavity by pouring the molten metal added with a proper amount of an inoculant based on the Si amount of core material composition to the high-chromium outer layer of the specific Cr amount and piercing a cavity. CONSTITUTION:A vertical mold 9 is constituted by a centrifugally casting mold 4 having therein an outer layer 1 of high chromium containing 13-27wt% Cr and upper, lower dies 7, 6. Molten ductile cast iron is then poured through the pouring basin 8 of the upper die 7. At this time, an inoculant 14 of Fe-Si base or the like is continuously and uniformly added at 0.1-1.0wt% based on the Si amount in the molten metal composition to the core material molten metal from the hopper 13 of the pouring basin 8. Next, strain relief heat treatment and roughing are applied to the composite roll blank material 2, after which a heater insertion hole 2' is pierced. The reason for limiting the amount of additin of the inoculant is: If it is added more than the limited amunts, the molten metal slag amount of the inoculant increases and the interposition of foreign material at the interface between the outer layer and the core material becomes likely to occur.

Title: Magnetic recording medium
Inventor: NAKAMURA KYUZO
IPC: G11B5/66
Filed: 1989-05-12
Abstract: PURPOSE:To obtain an intrasurface recording-type magnetic recording medium with improved coercive force by adding at least P in a Cr film during the process of continuous formation of Cr film and Co-alloy film on a nonmagnetic substrate. CONSTITUTION:The Cr film as a base layer is formed on a nonmagnetic substrate, on which the Co-alloy film and a C film are formed. At least phospher is incorporated into the Cr base film to cause intergranular segregation of P in Cr grains, since P hardly forms solid solution in Cr. This prevents Cr grains from coarsening and promotes isolation of the grains from one another. Thereby, grains in the Co-alloy film formed on the Cr film are also isolated, which improves the coercive force of the medium compared to a conventional one which has a base layer of a Cr-alone film without addition of P.

Title: Serial communication system and its method
Inventor: USHIO YUKIHIDE
IPC: H04L29/08
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To hold one of plural types of input information and to eliminate the need for adding a new signal against an instruction given from a master station, by allowing a slave station to send to information to the master station in response to a specified timing that is detected based on a control signal received from the master station. SOLUTION: A input selector circuit 1 of a slave station inputs information of parallel inputs A and B to an input latch circuit 2 in each bit via an AND-OR circuit and then selects information on the input A or B by means of a communication reset signal received from a master station and inputted to a counter circuit 6. In a communication operation mode, a communication reset signal is turned on and the parallel input information to be returned on decided by the execution of serial communication. When the information on the input B is selected, the communication reset signal is turned off. When the information of the input A is selected, a transfer clock is directly turned on and the count value of a master station timing counter is increased. Then the output equivalent to a single transfer clock is over.  Thus, it's possible to omit the addition of a new control signal for selection of the parallel input information by setting a reset timing which is different from the transfer timing.
