Title: Production of glass containing halogen and copper
Inventor: SUGIMOTO NAOKI
IPC: C03C3/11
Filed: 1993-04-02
Abstract: PURPOSE:To completely prevent copper from being volatilized in the production of glass contg. at least one halogen and copper by adding a copper raw material to a glass raw material batch after completion of the melt-down of the glass raw material batch. CONSTITUTION:In the production of glass contg. at least one halogen selected from Cl, Br and I and copper, the volatilization of copper is completely prevented from occurring by adding the copper raw material (e.g. glass cullet contg. copper) to the glass raw material batch after completion of the melt-down of the glass raw material batch. Copper is volatilized together with the halogen at the time of melting down the glass raw material batch in the initial stage of the melting and therefore the volatilization loss of copper can be prevented from occurring by adding the copper raw material after completion of the melt-down of the glass raw material batch. The amount to be added of compounds contg. copper is determined so that the glass contains finally the desired amount of copper. Any copper raw material which is glass contg. copper and contains copper in an amount equal to or more than that corresponding to the desired final copper content of the glass may be used. However the copper raw material having a higher copper concn. is preferred to efficiently add copper to the glass raw material batch. More specifically, the copper raw material having a copper content at least five times as much as the final copper content of the glass is particularly preferred.

Title: High frequency ampere meter
Inventor: KAWAMURA SHIGERU
IPC: G01R19/28
Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a high frequency ampere meter which does not need an external power source by providing a rectifier for rectifying the output of a level adjuster for adjusting a high frequency input level and a stabilizing power source for stabilizing its output. SOLUTION: A high frequency input from a current transformer(CT) 1 and a coupler 6 is controlled to an optimum level by a level adjuster 8. Control of the level adjuster 8 is done by feedback via a level determiner 7 at this time. The output of the level adjuster 8 is rectified by a rectifier 9, whose output is stabilized to required voltage for an amplifier by a DC/DC-converter or the like in a stabilizing power source 5A. Thus in a machine such as an interface panel of a medium frequency broadcasting apparatus which does not need a commercial power source, a high frequency power meter can be easily used. That is, it is not necessary to lay the commercial power source only for the high frequency power meter.

Title: Light-receiving element
Inventor: YANO HIROSHI
IPC: H01L31/10
Filed: 1991-05-02
Abstract: PURPOSE:To reduce a dark current to improve characteristics of pin-PD by making the mesa diameter of p-layer at least about 15mum smaller than that of i-layer in a light-receiving element composed of mesa pin-PD. CONSTITUTION:After an n-InP layer 2, i-GaInAs layer 3 and p-GaInAs layer 4 becoming pin-PD are formed respectively and successively on a semi-insulating InP substrate 1 and a mesa processing is conducted, an insulating film as a surface properties coat, i.e., SiN film 5 is formed by a method such as p-CVD. At the time of mesa processing, the mesa diameter of the p-GaInAs layer 4 is made smaller than that of the i-GaInAs layer 3. In the i-GaInAs layer 3, accordingly, a depletion layer stretching from the p-GaInAs layer 4 remains only within the i-GaInAs layer 3 without reaching the interface between the surface of the mesa and the insulating film. A dark current is reduced consequently.

Title: Electron synchrotron
Inventor: OKUYAMA TOSHIHISA
IPC: H05H13/04
Filed: 1987-04-27
Abstract: PURPOSE:To prevent a local temperature rising, constrain generation of an excess current, and ease manufacturing by arranging a copper member in a synchrotron emitted light irradiation part of a vacuum vessel, and manufacturing a synchrotron emitted light non-irradiation part with stainless steel. CONSTITUTION:A vacuum vessel 1 is made of stainless steel and has a configuration in which steel-made parting plates 7 are installed adapting ejection of a synchrotron emitted light 4 in the inside of the vessel 1. The synchrotron emitted light not ejected from a port 5 is irradiated to surfaces of such plates 7. Because plates 7 are made of copper, heat conduction is faster compared to the case where the synchrotron emitted light is irradiated to the stainless- made parting plate. This enables a local thermal deformation to be prevented, a thermal desorption gas blowoff quantity to be decreased, generation of an excess current to be decreased, and thereby the structural reliability of the vacuum vessel is improved.
