Title: Radiotherapeutic glass and its manufacture
Inventor: KOKUBO TADASHI
IPC: A61M37/00
Filed: 1994-02-09
Abstract: PURPOSE:To provide a glass in which radioelement ions are stably implanted by distributing element ions which can radiate beta ray by radiation of neutron near the surface of the glass body, by forming a membrane of oxide series glass around this ions, and by making on oxide nitride exist in the neighbourhood of the ions. CONSTITUTION:Charged P<+> ion particles are implanted into a silica glass on a specified condition, N<+> ions are also implanted. At this step, the ions are colloidal and a crack is created in the silica glass accompanied by the ion passing. In succession, when the silica glass is primary-heated for example at 400 deg.C in hydrogen gas, P colloid grows big in the silica glass without sublimation. Thereafter, when the silica glass is secondary-heated for example at 900 deg.C in oxigen gas, an SiO2-P2O5 series glass membrane is formed surrounding the P colloid, and as a result, the crack of the silica glass is closed. Therefore, the presence of this membrane makes P hard to elute into liquid as well as hard to sublimate.

Title: Operational amplifier
Inventor: HAYAKAWA TATSUO
IPC: H03F3/45
Filed: 1984-02-29
Abstract: PURPOSE:To improve the dielectric strength by providing a level shift circuit keeping a collector-emitter voltage of a transistor (TR) constant and a bias circuit keeping the operating range of the TR active. CONSTITUTION:TRs T16, T17 and a constant power supply W2 constitute a bias circuit to TRs T14, T15 and both the TRs T14, T15 are kept to an active region. Furthermore, a minute current flowing from a power terminal V1 to a power terminal V2 through the TRT15, diodes Z1-Z3, and the TRT16 pushes up the emitter potential of the TRT15 by a voltage drop of the diodes Z1-Z3 to a base potential of the TRT14. Since the resistance value of a resistor R5 is small, the collector-emitter voltage of an output TRT13 is limited nearly to the voltage drop of the diodes Z1-Z3. That is, the dielectric strength of the operational amplifier is boosted by limiting the maximum collector-emitter voltage loaded by the TRT13 by means of said boostrap circuit.

Abstract: PURPOSE:To improve the quantity and reliability of electronic parts package by moving a distance sensor above a lead terminal at a constant speed and inspecting the curvature and flying/sinking states of a terminal at the same time with the signal output of the sensor. CONSTITUTION:A package molding part 1 is fixed on a base 21 and a distance sensor body 3 is moved by a stepping driving circuit 10 in the array direction of lead terminals 2a-2d.

Title: Laser working device
Inventor: KOMATSU TADANORI
IPC: H01S3/00
Filed: 1981-03-19
Abstract: PURPOSE:To keep always working conditions and positioning constant to prevent the generation  of defective goods, by detecting the inclination of the optical axis of a laser beam and correcting the inclination of the optical axis. CONSTITUTION:When the optical axis of a laser beam 6 is a reference optical axis 6a, the  deflection value of all of outputs from a split sensor 45 of a movement detecting device 12 is  (0), and all of outputs of a split sensor 54 of an inclination detecting device 13 are equal to one  another and the deflection value is (0). Consequently, no output is generated from a discriminating device 14 for the first and the second operating devices 5 and 8. When the optical axis  is a moved optical axis 6b obtained by moving the reference optical axis 6a in parallel, deflection values in directions of axes X and Y are (0) together because the optical axis of a reflection detecting light 52 incident to a detecting lens 53 is parallel with the optical axis of the detecting lens 53. The second deflecting material 7 is moved forward and backward by the output  of the discriminating device 14 to correct the optical axis. When the optical axis is an inclined  optical axis 6c obtained by inclining the reference optical axis 6a, the second deflecting material 7 is rotated to correct the inclination, and simultaneously, the material 7 is moved forward  and backward to move the optical axis in parallel, and the optical axis is corrected by forward and backward movement of the material 7 again after correction of the inclination, thus  making the optical axis coincident with the reference optical axis 6a.
