Title: Tracking device for reproduction of three layer recording signal
Inventor: MURABAYASHI NOBORU
IPC: G11B15/467
Filed: 1989-04-25
Abstract: PURPOSE:To prevent a depth recording signal from being remarkably lowered by setting a tracking point for the reproduction of a recording medium between the optimum track point of each signal track on which depth recording is performed. CONSTITUTION:A PCM signal depth-recorded on the second layer of a magnetic tape 5 is reproduced by PCM heads 3a and 3b. Also, an AFM signal depth- recorded on the third layer of the tape 5 is reproduced by AFM heads 2a and 2b. In such constitution, tracking correction is performed so as to increase the reproducing output of depth-recorded AFM signal and PCM signal as far as possible. In other words, a system controller 32 decides a practical tracking point to trace the tape 5 actually based on peak detecting signals S1 and S2 supplied from peak detectors 22 and 31, respectively. Then, a correction signal S4 is generated, and is derived to a tracking circuit 35. In such a way, it is possible to prevent the reproducing S/N of the depth recording signal remarkably deteriorating.

Filed: 1987-04-28
Abstract: PURPOSE:To form a high accuracy pattern on a body to be worked by coating the body with a reflecting metallic film, forming a pattern of a prescribed shape on the film by photolithography and radiating laser light. CONSTITUTION:A Cr underlayer 2 is vacuum-deposited on the surface of borosilicate glass 1 and a reflecting gold film 3 is further vacuum-deposited and coated with a cyclized rubber type photoresist film 4. A photomask 5 is positioned on the film 4 and the film 4 is exposed, developed with a developer, rinsed with a rinse, dried and heat treated to form a resist image. The unnecessary part of the gold film 3 is etched with aqua regia and the unnecessary part of the Cr underlayer 2 is etched with sulfuric acid to form a pattern. After the photoresist film 4 is removed with a mixed soln. contg. sulfuric acid and hydrogen peroxide, CO2 laser beams of about 2mm diameter are scanned to work the surface of the glass 1 and then the gold film 3 and the Cr underlayer 2 are removed. Thus, accurate laser beam working for forming a pattern of a complex shape is carried out.

Title: Bus controller
Inventor: MAEDA KENICHI
IPC: G06F9/46
Filed: 1980-07-31
Abstract: PURPOSE:To shorten a bus access time in case of using a bus of a lowest-order priority device, by constituting so that a use permission signal to the lowest-order priority device can be received directly by a bus controller. CONSTITUTION:When there is no bus using request from high-order priority device groups 200-400, and there is only a bus using request from a lowest-order priority device 100, a bus controller 500 generates a bus using inhibition synchronizing signal to a signal line 16. In this case, the device 500 sends out a bus using permission signal through a signal line 14 to the device 100, and does not send it out to the devices 200-400. However, in case when a bus using request has been sent out from the devices 200-400 during a deciding time which has been prescribed in advance, after the bus using inhibition synchronizing signal has been sent out; priority is decided during said deciding time, and after a prescribed time, the bus using permission signal is sent out through the signal line 14. In this way, a use permission signal to the device 100 is received directly, the bus access time is shortened.

Title: Monitoring device for humidity of hydrogen gas
Inventor: MORIHARA MASAYUKI
IPC: H02K9/24
Filed: 1979-08-22
Abstract: PURPOSE:To supply hydrogen gas in stationary condition, by using a drier, a hydrogen gas detector and an amplifier from an electric signal from the detector to continuously monitor whether the hydrogen gas is dry or not. CONSTITUTION:The hydrogen gas, which is circulated due to a pressure difference caused by fans 3 attached to the rotor 2 of a rotary electric machine 1, is dried by the drier 4 and conducted to the hydrogen gas humidity detector 5, which reacts with the minute moisture content of the hydrogen gas and converts the moisture content into an electric signal to continuously inform through the amplifier 6 whether the hydrogen gas in operation is dry or not. The same action is performed also when the drying agent of the drier 4 exceeds humidity absorption capacity. It is thus continuously monitored whether the hydrogen gas is dry or not. This results in supplying the hydrogen gas in stationary condition.

IPC: C22C37/00
Filed: 1984-05-25
Abstract: PURPOSE:To improve the strength of a crank shaft with an easy treatment by subjecting the prescribed points of a cast iron crank shaft to high-frequency heating and quick cooling to form a bainite structure layer and grinding away the martensite structure layer formed atop the layer. CONSTITUTION:Pin parts 2 of the cast iron crank shaft 1 are enclosed by semi- toric hardening coils 5, 5' in a way as not to contact therewith in the stage of subjecting the pin parts 2 to the induction hardening treatment. High-frequency current is then passed to the coils 5, 5' to heat the parallel parts 2a and fillet parts 2b of the pin parts 2 to the eutectic point of iron and carbon or below and thereafter the crank shaft is allowed to cool to about A1 transformation point (650-800 deg.C). Water or the like is further injected from cooling water injecting holes 6, 6' to cool quickly the heated parts down to 200-300 deg.C and to harden said parts. The martensite structure layer 3 having about 0.5mm. thickness and the bainite structure layer 4 having about 1-5mm. thickness therein are thus formed. The layer 3 is ground away.

Filed: 1978-08-31
Abstract: PURPOSE:To resume copying easily and securely, by detecting jamming of recording body in the transfer passage, and continuing the jam detecting action even after cutting off power source. CONSTITUTION:When jamming of copying paper in the transfer passage is detected, after starting paper feed, by comparing the counting of clocks from detection of paper discharge by a roller 36 at the outlet of copying paper until turn-on of microswitch 154 with the set value depending on the size of copying paper 155, the jam is displayed, and the specified relay is held so far as the reset switch is not operated. Therefore, the jam detecting action continues even after cutting off the power source. On the other hand, the photosensitive drum stops at the specified position on the basis of the memory of the operating state of the main switch and door switch which are sequence-contorolled at the time of power cut-off. Hence, when resuming copying after clearing the jam, the sequence control is not disturbed, and if copying is resumed without clearing the jam, the jam detecting action is continued, so that the completion or not of the jam clearing may be judged.
