Title: Optical memory device and its production
Inventor: HIROKANE JUNJI
IPC: G11B11/105
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To inhibit at least one of cross talk, cross writing and cross erasure by selectively oxidizing a recording magnetic layer formed on a side wall part between land and groove. SOLUTION: When a recording magnetic layer 3 is formed and then a selectively oxidized layer 11 is formed in a very small thickness, the thickness of the selectively oxidized layer 11 formed on a side wall 9 is also made about half of the thickness of the selectively oxidized layer 11 formed on a land and a groove. In the case of subsequent holding in an oxygen-containing atmosphere, the selectively oxidized layer 11 formed on the land and the groove is impermeable to oxygen and protects the recording magnetic layer 3 from oxidation because it has a sufficient thickness and continuity. The selectively oxidized layer 11 formed on the side wall 9 is easily permeable to oxygen because it loses continuity in accordance with the reduction of the thickness. Only the recording magnetic layer 3 formed on the side wall 9 is therefore oxidized.

Title: Measuring device for error of freely curved surface
Inventor: MIYATANI TAKAO
IPC: G01B11/24
Filed: 1984-11-20
Abstract: PURPOSE:To improve the operativity of free surface error measurement by guiding light from a convergent illumination system so that the light is converged to a specific diameter at a regular position, and guiding its reflected light to a detection position. CONSTITUTION:When a measured point is at a measured position on a regular plane, laser light from a prism 4 and laser light from a half-mirror 5 are guided to the measured position, and their light spots are superposed on each other at the measured position on the regular plane. For the purpose, the prism 4 is turned over and the reflected light from the light spot on the regular plane is guided to a detecting light shield plate 6 through the prism 4, so that the reflected light from the light spot of the laser light from the half-mirror 3 is guided to the aperture of the light shield plate 6. A detector 7 for the quantity of photodetection detects the quantity of the reflected light and outputs its detection signal to a decision circuit 9. Then, the circuit 9 compares the regular quantity of photodetection with the quantity of photodetection based upon the detection signal to judge whether the measured position is on the regular or not. Then, the circuit 9 outputs an output signal corresponding to the measured position.

Title: Hot water storage type hot water heater
Inventor: NISHIDA YAYOI
IPC: F24H1/18
Filed: 1987-09-29
Abstract: PURPOSE:To enable hot water of desired temperature to be fed at any desired time by a method wherein water is fed in such a way as a hot water temperature within a hot water tank is not less than a specified temperature, and if the hot water reaches the specified temperature after heating operation, water is fed again and the water is supplied up to a required amount of hot water and then heating operation is carried out. CONSTITUTION:A water supplying means is comprised of a thermistor 2, a hot water supplying port 6 arranged between water level sensors 41 and 42, a solenoid valve 7 for opening or closing a water feeding valve, and a control part 72 for controlling energization of a solenoid valve 71 in response to signals from the water level sensors 41 and 42 and a signal from a thermistor 3. In case that water within a hot water tank 1 is less than a water level sensor 41, the solenoid valve 71 is opened and water is fed until the water indicates a water level of a minimum water level sensor 41, and a heater 2 is turned ON and then a heating operation is started. When the temperature is increased more than the set temperature, the heater is turned OFF, the solenoid valve 71 is opened again to feed water. If the water is decreased down to such a limit temperature as one capable of feeding hot water, the solenoid valve 71 is closed and the water feeding is terminated. If the temperature within the hot water tank 1 reaches the set temperature, the heater 2 is turned OFF. The hot water temperature is always kept more than a specified temperature and so the desired hot water can be attained at any time.

IPC: B32B15/08
Filed: 1990-09-14
Abstract: PURPOSE:To prevent moisture absorption from being recaused in the interval wherein the surface of a steel sheet is heated and dried and thereafter this surface is coated with resin and to secure good adhesive properties by drying the surface of the steel sheet just before this surface is coated with resin. CONSTITUTION:Two sheets of steel strips 1 are unwound from an uncoiler 9 and the surfaces are purified by a purifier 2 and thereafter dried while passing through a heater 3. In this heating and drying, it is necessary that the heating temp. is regulated to >=130 deg.C to <=160 deg.C and the heating time is regulated to >=1sec. After the steel strips are dried and then passed through a cooler 4 and cooled at <=50 deg.C, the surfaces of the steel strips are coated with resin. One side of steel strips 1 is coated in a coater 5 and the other hand of the steel strips 1 is contact-bonded and simultaneously coated when both steel strips are stuck by a contact-bonding roll 6. Therefore in the case of providing the heater 3 before the coater 5 and the contact-bonding roll 6, even when silica-contg. chromate treatment has been performed for steel strips 1, coating of resin can be performed within several seconds or some tens seconds after drying. Thereby the damping steel sheet can be produced which is excellent in the adhesive properties of resin and the steel sheet.

Title: Ring-status interrupting system
Inventor: SUZUKI HIDEO
Filed: 1984-11-20
Abstract: PURPOSE:To improve the overall putthrough and to relieve the load of the CPU by so forming the system that each node transmits a frame to itself in order to test its state of coupling with the ring and by checking its result by a dedicated LSI, and further generating an interruption in the firmware based on the above result. CONSTITUTION:The transmission frame 500 from the node A goes around a ring, and is inputted to the receiving circuit of a TPC (token passing controller) 10. If the inputted byte is a source address part SA, the TPC10 compares it with its own address (MA). And the comparison-result is expressed in the third bit and the second bit of a receiving status register RXFS1028. If it is 00, then SA=MA. At this time, the outputs of an inverting circuits 1034 and 1035 shown in figure (b) become a logic 1. In case when the ring turn-around test is made valid, an FF1036 is set by an MUP20. An FF1037 is a storage element to show whether or not the status is valid, and shows that the status information is exactly set in an RXFS. Accordingly, if the circuit shown in figure (b) is used, when the bits 1036 and 1037 both are logic 1 and hence are in a valid status and if SA=MA, a turn-around interruption FF1039 is set.

Filed: 1992-08-20
Abstract: PURPOSE:To freely select a successive shooting speed corresponding to the speed of a subject as a photographer intends by outputting a successive shooting speed adjustment signal for adjusting the operation speed of a motor to a control circuit during successive photographing. CONSTITUTION:Once a variable successive speed mode is selected, a photographic mode switching circuit 1 turns on a switch 6 and a successive shooting speed adjusting circuit 5 and a CPU 2 are connected.

Namely, the winding speed of a film motor 4 is adjusted after the one-frame photographing and a control signal is outputted to a CPU 2. Therefore, even if the moving speed of the subject varies during the successive photographing, the successive shooting speed can be increased following up the variation in the moving speed to enable detailed photographing.
