Title: Ion beam sputtering method and device
Inventor: MATSUKAWA NAOKI
IPC: H01L21/203
Filed: 1987-10-22
Abstract: PURPOSE:To prevent the damage of a substrate as well as to provide directional properties to sputtered particles by projecting ion beams having specified energy on a target at a certain angle under scanning. CONSTITUTION:An inert gas is introduced into an ion generation chamber 12 and ionized. The resulting ions are extracted as beams and the ion beams are introduced into a sputtering chamber 15 through an ion beam line 14 fitted with an X-Y scanner 13. At this time, the angle of incidence of the ion beams on a target 6 is arbitrarily changed by changing the angle of the target 6 through a target holder 16, and sputtered particles having directional properties are released and deposited on a substrate 4. The ion beams are scanned in X-Y direction during sputtering to uniformly deposit a film. The damage of the substrate 4 by the sputtered particles is prevented by regulating the energy of the ion beams to <=1.5keV.

Title: Method for quick discharge of molten metal in molten metal supply system in pressurization type molten metal holding furnace
Inventor: KUBOTA MASAMITSU
IPC: B22D39/06
Filed: 1986-11-10
Abstract: PURPOSE:To quickly and fully discharge the entire molten metal in a supply system into a supply chamber by mounting the suction pipe of the supply system to the position higher than the molten metal surface in the supply chamber which lowers when the pressure in a pressure chamber is released, thereby discharging the molten metal on the lowered molten metal surface by gravity. CONSTITUTION:A discharge valve 30 is fully opened by a valve operator 36 and a discharge valve driving part 30a when an emergency discharge valve operator 36a is operated. The pressure in the pressure chamber 12 is then quickly released and the molten metal surfaces in the chamber 12 and in the supply chamber 14 are averaged to the same molten metal surface Lc. A suction port 18a is positioned upper than the surface Lc at this time and since the supply system 16 is disposed upper than the suction port 18a, the entire molten metal M in the system 16 is quickly and surely discharged by gravity into the chamber 14.

Abstract: PURPOSE:To prevent a ceramic cap from displacing to a ceramic base by forming a projection for preventing the cap from displacing to the base by engaging the cap with a recess of the base. CONSTITUTION:A thicker projection 8 than a periphery 4 is formed at the center of a cap 3 for closing a hole of a recess 9 of a base 1. The width of the projection 8 coincides with the recess 9 of the ceramic base 1, the projection 8 is engaged with the recess 9 in case of baking in oxidative atmosphere, the periphery 4 of the cap 3 is seated on a solder glass 5, and the projection 8 is engaged with the recess 9 to position the cap 3 to the base 1. Accordingly, when fusion-bonding with the solder glass, the base 1 and the cap 3 are positioned by engaging the projection 8 with the recess 9. Thus, it is not affected by the influences of a vibration at conveying time, gas-flow at baking time, and the cap 3 can be accurately fusion-bonded to the base 1. Thus, the operating efficiency in case of handling is improved to improve a yield.

Title: Semiconductor laser
Inventor: YOSHII HIROKAZU
IPC: H01S5/00
Filed: 1994-10-28
Abstract: PURPOSE: To inhibit a diffusion of a dopant in a P-type clad layer into an active layer and to provide a highly reliable semiconductor laser. CONSTITUTION: A multiple distortion diffusion stopping layer 12 constituted by laminating alternately strained layers 12a of a grating constant larger than that of a GaAs layer and non-strain layers 12b of the same grating constant as that of the GaAs layer several to several tens of layers is formed between an active layer 4 and a P-type clad layer 6. A strong electric field is generated in the respective interfaces between the layers 12a and 12b of the layer 12 and impurities to come diffusing from the second conductivity type clad layer 6 are captured in the interfaces. By forming alternately the layers 12a and the layers 12b into a multilayer, a power to inhibit a diffusion of a dopant in the layer 6 is largely enhanced. Thereby, the diffusion of the dopant in the layer 6 into the layer 4 can be effectively inhibited and a highly reliable semiconductor laser can be realized.

Abstract: PURPOSE:To enhance the manipulability of a vacuum cleaner by arranging a storage chamber for a motor or a dust collecting bag in the vicinity of a suction port in order to allow the storage chamber to be moved, relative to the suction port, so that the storage chamber is located near the suction port in order to obtain a low gravitational center if a wide floor surface is to be cleaned, but it is shifted upward if a narrow floor surface is to be cleaned in order to prevent the storage chamber from hindering the cleaning operation. CONSTITUTION:A joint 6 formed to a suction port 4 is connected to a control part 8 through the intermediary of a support column 10, a motor-driven blower 12 and a dust collecting bag 14 are stored in a storage chamber 16. Further, a cord 24 from a motor 12B in the motor-driven blower 12 is stored in the storage chamber 16 which is supported by the support column 10 so as to be axially swingable, and accordingly, the storage chamber 16 can be moved toward the control part 8 until the distance between the storage chamber 16 and the suction port 4 becomes a value L. If a wide floor surface is to be cleaned, the storage chamber 16 is shifted downward so that the vacuum cleaner can have a low gravitational center and is therefore stabilized. Meanwhile, if a narrow floor surface is to be cleaned, the storage chamber 6 is stopped at the control part 8 side, and cordingly, the storage chamber 16 does not hinder the cleaning operation.

Title: Image recorder
Inventor: MATSUYAMA YASUO
IPC: G03G15/20
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To reduce a noise due to the rotation of a fan motor by rotating the fan motor by the absolute minimum number of rotations while taking the balance of temperature rising inside the machine and a fan noise into consideration. SOLUTION: The temperature of a fixing roller is determined based on a detected signal from a thermistor 12 by a control circuit 20 before recording operation. And also the rotational speed of the fan motor 14 is set based on the number of fan rotations corresponding to a temperature obtained from a table stored in a RAM 22. For instance, when the detected temperature of the thermistor 12 at the time of starting is 0-24 deg.C, the fan motor 14 is set to be in a stopped state until the temperature of the fixing roller reaches 120 deg.C by being heated by a heat lamp 11. When it is >=120 deg.C, the fan motor 14 rotation is decreased by 50%. Then, when printing is finished and the detected temperature of the thermistor 12 becomes 120 deg.C, the fan motor 14 is stopped.

Abstract: PURPOSE: To prevent malfunctions by limiting locking and unlocking action according to the result of comparison of a transceiver received signal level temporarily stored in response to detection of the leaving behind of portable equipment with a newly received signal level. CONSTITUTION: A CPU 8, using a door lock detection switch 12, checks whether a door lock instruction or a door unlock instruction is given. In the case of the door lock instruction, communication with portable equipment 1 is repeated (n) times and (n) received signal levels are stored in a memory. Identity of (n) data is checked, and if they are not identical, the CPU 8 determines that the portable equipment 1 is not left behind, then clears a part of the memory and sets R<0> at zero. When the switch 12 is on, the condition of the portable equipment 1 is checked, and if it is left behind, a value of an A/D converter 10 for ID codes is compared with R<0> which is determined according to whether or not an A/D converted value fluctuates when the door is locked.  When the difference between the values is greater than a specified value B, the CPU 8 determines that the portable equipment 1 has been moved, and transmits a door lock signal.
