IPC: C04B37/02
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To remove an unnecessary solder material existing between circuit patterns, by using a chemical made of fluoric acid alone, a mixed solution containing fluoric acid and at least one inorganic acid selected from nitric acid, sulfuric acid and hydrochloric acid, aqua regia, or a sodium hydroxide solution, and/or a potassium hydroxide solution. SOLUTION: Solder materials 2, 3 are arranged on a ceramic board 1, and non-segmented metal plates 4, 5 are arranged on both sides of the board. Metal circuit patterns 9 are formed using an etching resist 7. In this case, an unnecessary solder material 11 is generated between the patterns 9. Thus, by performing chemical treatment for 5-20 minutes in the case of an Ag-Cu-Zr solder material, 10-30 minutes in the case of an Ag-Cu-Zr-TiH2 solder material, and 10-30 minutes in the case of an Ag-Cu-Zr-TiH2 -AlN solder material, using a chemical of 80 deg.C containing 10% of fluoric acid, the unnecessary solder material may be removed. In this process, the treatment may be made more effective by applying ultrasonic waves.

Title: Bias circuit in high frequency circuit
Inventor: ASHIDA HIROYUKI
IPC: H03F1/26
Filed: 1984-10-02
Abstract: PURPOSE:To stabilize a bias voltage by constituting the post-stage filter with an emitter follower transistor (TR) whose base and emitter are connected between a filter output terminal of the 1st stage and a bias output terminal and with a capacitor connected to said emitter. CONSTITUTION:A TRQ1 of emitter follower connection is used in place of a resistor constituting a post-stage LPF together with a capacitor C2. Through the constitution above, in viewing the post-stage filter circuit from the 1st stage LPF circuit comprising a diode D and a resistor R1 and a capacitor C1 connected in series therewith, the input impedance is very high, resulting that the time constant is very large. Since a base-emitter voltage of the TRQ1 is not so much changed even when a bias current iB changes largely, a bias voltage outputted at a bias output terminal K is not almost changed.

Abstract: PURPOSE:To prevent clogging caused by the curling of the lower end portion of bills by partially projecting the lower end of each of first and second guide faces through a housing receiving face while providing a hollow portion for permitting the movement of the lower end projecting portions of the first and second guide faces on this housing receiving face. CONSTITUTION:A prime mover side delivering means (delivery belt 2 side) starts moving perpendicularly to the surface of bills 20 based on a command and is moved while collectively holding the housed bills interposingly toward a driven side delivering means (retainer roller 12 side) up to a defined position. After removing the lower edges of the housed bills from a housing receiving portion 1a, the bills 20 in a lump are delivered by the delivering action of the prime mover side delivering means and the driven side delivering means until at least the bottom end portion thereof is exposed outside. Further, since the lower end ot a guide portion 6a is partly projected out through the housing receiving portion 1a at the time of housing, even if the bottom end of the bills 20 is curled, the bills can be prevented from being rolled into the corner of the housing receiving portion. It can be also prevented that the bills are transferred toward the housing receiving portion 1a at the time of delivering.

Abstract: PURPOSE:To produce a raw material for high-quality compound semiconductor single crystal in the production of a semiconductor of a compound containing a volatile component such as GaAs by Czochralski method using B2O3 as an encapsulant, by heating the semiconductor raw material and B2O3 at a temperature above the melting point of B2O3 in vacuum. CONSTITUTION:The raw material for the production of a group III-V compound semiconductor such as a GaAs single crystal by Czochralski method using B2O3 as an encapsulant is produced by the following process. A crucible 11 containing B2O3 and polycrystalline GaAs or a compound raw material of Ga and As 12 and B2O3 3 used as an encapsulant is put in a vacuum quartz tube 8. The content of the tube is heated at a temperature above the melting point of B2O3 (450 deg.C) with the electrical furnace 9 placed at the side of of the quartz tube 8 to melt the B2O3. The molten B2O3 covering the surface of solid GaAs or a mixture of Ga and As 12 is cooled and solidified. When a GaAs single crystal is pulled up from the raw material by Czochralski method, the evaporation of volatile As (a group V element) in the melting of GaAs can be prevented because the raw material of GaAs is covered with B2O3.
