Title: Connecting method of optical fiber
Inventor: NISHIMURA KUNITOSHI
IPC: G02B6/255
Filed: 1984-06-25
Abstract: PURPOSE:To keep optical fibers free from undue stress and to connect two pieces of the optical fibers with high reliability in the stage of welding and connecting the two fibers by connecting said fibers while controlling the axial force between the two fibers. CONSTITUTION:The two optical fibers 3, 4 are respectivey gripped by holders 1, 2. The holder 1 is fixed onto a base 7 supported by two pieces of parallel springs 8, 9 and strain gages 16, 17 are adhered to the surfaces of the parallel springs 8, 9. The springs 8, 9 deflect when the axial force acts at the top end of the fiber 3. The force is detected from the magnitude of the strain in this stage. The two optical fibers are so spaced and heated that the force acting axially on the fibers 3, 4 is first made zero, then the top ends of the fibers 3, 4 are butted to each other until the specified force is attained and while such force is maintained, the top ends are heated and thereafter the force acting axially on the fibers is decreased to the prescribed force. Since the fibers are welded and connecting under heating in such a state, the fibers are kept free from the undue stress.

Abstract: PURPOSE:To prevent insulation breakage of an X-ray tube by furnishing X-ray tube voltage restricting elements, which are put in continuity when a voltage exceeding a certain value is going to be impressed on the X-ray tube, absorb the impression energy, and restrict impressed voltage onto the X-ray tube. CONSTITUTION:X-ray tube voltage restricting elements (lightening protector) 17, 18, which are put in continuity when a voltage exceeding a certain value (normally an allowable value) is going to be impressed on an X-ray tube 15, absorb the impression energy, and restrict impressed voltage on the X-ray tube 15, are inserted between the positive and negative electrode sides of the outputs from rectifiers 11, 12 and a grounding terminal and connected parallelly with the X-ray tube 15. Accordingly, when a high voltage exceeding the allowable voltage for X-ray tube 15 is given externally in the event, for ex., of ground discharge to a power supply line, or when any reason has generated an overshoot exceeding the same allowable voltage, the lightening protectors 17, 18 are put in continuity so as to absorb the impressed energy. Thereby the overshoot voltage generated on the output sides of the rectifiers 11, 12 is absorbed to restrict the impressed voltage onto X-ray tube 15, which prevents the tube 15 from insulation breakage.

Title: Focusing method for optical information recording medium
Inventor: GOTO HIROSHI
IPC: G02B7/28
Filed: 1989-05-24
Abstract: PURPOSE:To reduce the blur of a spot by setting the power of a semiconductor laser, with which a sample area is irradiated, to intermediate power between reproducing power and recording power at the time of using a recording mode. CONSTITUTION:When the sample area is irradiated with the semiconductor laser at the time of using the recording mode, the power of the semiconductor laser is set to the intermediate power between the reproducing power and recording power. For example, at the time of the recording mode, a light flux, with which a sector is irradiated, is changed in three stages such as recording power Pw, reproducing power Pr and intermediate power Ps according to the emitting power of the semiconductor laser as a light source. In such a case, the influence of chromatic abberation to a focusing state is mutually distributed in a reverse direction to the recording power and reproducing power. Although the blur of the spot is generated to the recording power and reproducing power, the degree of the blur is reduced.

Title: Non-volatile semiconductor memory
Inventor: IMAMIYA KENICHI
IPC: G11C29/12
Filed: 1987-05-27
Abstract: PURPOSE:To secure a sufficient power supply margin by means of all access operation including normal reading operation by providing the titled memory with a circuit for changing a data reading reference in a reading mode and a program verify mode. CONSTITUTION:At the time of the program verify mode, a dummy cell 11 capable of applying earth potential to its gate is turned off and a reference potential generated at that time is expressed by V2. At the time normal reading, potential Vcc is applied to the gate of the dummy cell 11, the dummy cell 11 is turned on and generates a reference voltage shown by V1, then V1<V2 is formed. Namely, the reference input potential VREF of a sense amplifier 1 at the time of the program verify mode is higher than that of normal reading operation. Since the bit line potential VBL of a memory cell side circuit 2 is increased when a written memory cell is selected, a reference for deciding whether the memory cell is written or not is made severe. Consequently, a sufficient power supply margin can be secured by all access operation including normal reading operation.
