Title: Laser power monitoring device
Inventor: MIYAMOTO NOBUYUKI
IPC: H01S3/00
Filed: 1988-11-18
Abstract: PURPOSE:To exactly execute monitoring in a short time by holding a detecting part at a constant temperature, irradiating it by a laser for a prescribed time, and monitoring the laser power from a rise temperature caused by the irradiation after a prescribed time. CONSTITUTION:A laser power detecting part 3 is usually held at a constant temperature through a heater 32 by a temperature controller 44. In this state, at the time of monitoring the laser power, a laser irradiation command is given to a laser generating part 1 by a timing control circuit 41, and also, by cutting off a heater 32 by a switch SW1, a temperature control is suspended. Subsequently, the detecting part 3 is irradiated by a laser for a prescribed time through a laser emitting part 2, its temperature rises, and it returns to a constant temperature after a prescribed time. Its rise temperature is detected by a temperature sensor 31, and thereafter, compared with a set value of an upper and lower limit temperature setting device 43 by a comparator 42. By an output of the sensor 31 which is varied in accordance with a result of its comparison, the laser power can be monitored.

Title: Linear accelerator
Inventor: KIMURA KATSUICHI
IPC: H05H9/00
Filed: 1987-11-16
Abstract: PURPOSE:To have a beam with low emittance, large current, and good energy spectrum effectively by furnishing an accelerator tube to accelerate the beam, which is velocity modulated by No.1 and No.2 prebunchers. CONSTITUTION:A beam from an elecxtron gun 1 is bunched by a plurality of prebunchers 2, 5, and a standing wave accelerator tube 3 as a high electric field accelerator is used. Puncher cavity of th standing wave accelerator tube 3 is restricted to only one. With a plurality of prebunchers 2, 5, accordingly, it is required only to give a mild velocity modulation even in case bunching is to be made to the same phase width, compared with a one using a single prebuncher, and thus the energy spectrum width of the acceleration beam can be lessened. Thus a linear accelerator is obtained, which can accelerate the beam with good energy spectrum, low emittance, and high current.

Abstract: PROBLEM TO BE SOLVED: To suppress the consumption of the battery in the adapter with simple constitution by detecting the rotation of a magnet which rotates associatively with a motor for disk cartridge driving with the output of a sensor detecting magnetic field variation and supplying the electric power from a power source to a driving part communication interface part. SOLUTION: When the disk cartridge type adapter is inserted into a floppy disk drive(FDD) 70, the motor rotation detection sensor 54 senses magnetic flux variation due to the rotation of the disk attracting magnet in the FDD 70 and informs an MPU 83 of that by interruption to decide the access state of the FDD 70 when the MPU 83 decides that there is the magnetic flux variation and the stop state of the FDD 70 when not. In the stop state of the FDD 70, the power supply from the battery part to the communication interface part 91 for the FDD 70 is stopped and in the access state, on the other hand, the electric power is supplied to the communication interface part 91.

Title: Liquid growth equipment
Inventor: ISHINO MASATO
IPC: H01L21/208
Filed: 1985-12-24
Abstract: PURPOSE:To enable reduction of the friction of a weight at the time of fall down by making the thickness of the periphery of the weight thicker than the thickness required for an assumed rectangular parallelopiped with the same weight and the same bottom area as those of a weight which causes no drag of a melt. CONSTITUTION:The thickness (d) of the periphery 10 of a weight is made thicker than the thickness (d') of an assumed rectangular parallelopiped of the same bottom area and the same specific gravity to the weight. Such a weight has sufficient thickness at the periphery 10 and the fall down of the weight at the time when a melting material is melted causes no friction with the side wall of a growth bath by tilting. Further, since the weight is the same even though the thickness of the side surface 9 is increased, the dragging of the melting material at the time of the sliding of a base plate due to the load of too much weight on the melting material is not induced and a good epitaxial growth can be achieved.

Title: Disk substrates provided with liquid stopping grooves constituting optical disk
Inventor: KITANO RIYOUKO
IPC: G11B7/24047
Filed: 1997-10-07
Abstract: PROBLEM TO BE SOLVED: To prevent excessive adhesive from spreading to the radial direction of an optical disk in a spreading process in spite of an error due to the design of disk substrates by forming liquid stopping grooves in a multistage in the disk substrates. SOLUTION: When there is distortion in manufactured disk substrates, since absorbing effects of adhesive are different, the spread end R1 of the adhesive passes through a first step part 1 to reach the inlet of a second step part 2. Moreover, it reaches a third step part 3 based on the extent of the distortion. At the time the adhesive R moves from the first step part 1 to the second step part 2 or it moves from the second step part 2 to the third step part 3, since the gap between the disk substrates becomes adruptly narrow at respective inlet parts, resistance forces are generated at these parts when the spread of the adhesive R progresses. Consequently, even when absorbing effects are different because of the error concerning quality, that is, the extent of the distortion, the spread end R1 of the adhesive is stopped by the resistance forces of the step parts. Thus, it is never generated that the spread end R1 reaches center holes of the disk substrates D.
