Title: Water tank of electronically exciting apparatus for water
IPC: C02F1/48
Filed: 1990-06-06
Abstract: PURPOSE:To prevent the generation of dielectric breakdown even when a water tank is brought into contact with or allowed to approach a wall of furniture by forming the water tank of an electronic exciting water making apparatus from a metal/ceramic double water tank. CONSTITUTION:A metal plate 10 is bonded to the inside of a ceramic water tank 2 and natural hard wood charcoal 3 is arranged to the bottom part thereof and the ceramic plate 4 suspended from the upper lid of the water tank 2 by a metal spring 6 is brought into contact with the upper part of the natural hard wood charcoal 3. Further, a ceramic glass stand 8 is placed on the outer bottom part of the ceramic water tank 2 as the placing stand of said tank 2 in order to enhance insulation. The exciting voltage generated from an electronic excitation generating main machine 1 is sent into the ceramic water tank 2 by a connection conductor 7 to change the drinking water 5 received in the ceramic water tank 2 to electrolytic water. Since the water tank is formed from a metal/ceramic double water tank, dielectric breakdown is prevented and, therefore, it is prevented that the effect of the high voltage applied to the water tank is reduced by half or the electronic excitation generating main machine is damaged.

Title: Phase control unit
Inventor: HIRATA HITOSHI
IPC: H03L7/06
Filed: 1978-12-01
Abstract: PURPOSE: To secure the coincidence between the intermediate frequency and the free-running frequency of the voltage control oscillator by generating the voltage proportional to the phase difference between the output voltage of the phase comparator in the PLL circuit and the double input signals of the phase comparator and then controlling the oscillation frequency of the local oscillator via the generated voltage.  
     CONSTITUTION: The output of phase comparator 7 in PLL circuit 10 is used as the oscillation frequency control signal of local oscillator 1 via LPF16 and DC amplifier 17. And the output voltage of comparator 7 is turned to the voltage which is proportional to the phase difference between the input signal and voltage control oscillator VCO11. Using this voltage, the oscillation frequency of oscillator 1 is controlled to secure the frequency of the intermediate frequency signal delivered from mixer 2 which is equal to the free-running frequency of VCO11. Then the phase difference is always kept to 90° between output eO of VCO11 and output e i  of IF amplifier 3, thus ensuring the normal operation at all times for quadrature stereo demodulator circuit 5.

Abstract: PURPOSE:To remove moisture of the substrate surface completely to improve the quality of the sputtering-formed film, by irradiating the electromagnetic wave of an ultrahigh frequency in the sputtering bath or the preprocessing room adjacent to this bath in case that the thin film is formed onto the substrate surface by the sputtering method. CONSTITUTION:Substrate 3 for formation of a thin film is put on Teflon substrate holder 2 in sputtering bath 1. After air in sputtering bath 1 is evaculated by driving vacuum exhaustion system 11, magnetron oscillator 4 is excited, and the obtained electromagnetic wave of an ultrahigh frequency is led by waveguide 5 and is led into bath 1 through quartz glass plate 6 and is projected onto substrate 3. Water adsorbed to substrate 3 is energized by the electromagnetic wave and is dispersed dielectrically and is exhausted as water molecules from exhaustion system 11. Thus,  substrate 3 is dried completely, and the thin film of a superior quality is formed by  sputtering. In this case, a preprocessing room may be provided before the sputtering bath to move the substrate and subject it to dehydration and sputtering  processings.

Title: Atmosphere furnace
Inventor: NIIOBI MASARU
IPC: C21D1/74
Filed: 1985-07-08
Abstract: PURPOSE:To execute bright annealing with high quality at a low cost by adding a specific slight amt. of gaseous H2 to gaseous N2 which is an atmospheric gas in the stage of subjecting a coiled steel strip in a non-oxidizing state to the bright annealing in a heat treatment furnace using the gaseous N2 as the atmospheric gas. CONSTITUTION:The material 1 to be treated such as the coiled steel strip is first put into a charge side vacuum purging chamber A to prevent the intrusion of the external air into the succeeding preheating chamber B when the material 1 enters said chamber. The steel strip is preheated to a prescribed temp. by radiant tubes 3 in the chamber B and in succession thereof, the strip is put into a heating chamber C where the strip is heated and annealed by radiant tubes 6 to >=550 deg.C. The gaseous N2 contg. <3% H2 is introduced as the atmospheric gas into the chamber C. The gaseous O2 in the inexpensive gaseous N2 is removed by reacting with the gaseous H2 and the strip is heated in the high-purity N2 atmosphere. The material 1 is then introduced into a cooling chamber D and the oxygen-free N2 atmospheric gas in the heating chamber is cooled by a cooler 14 and is supplied by a pipe 12 to the cooling chamber D and is thereby cooled; thereafter, the strip is taken out through an outlet side vacuum purging chamber E. The bright annealing to provide the high surface quality is thus executed at the low cost.

Title: Laser oscillator
Inventor: KUMAMOTO KENJI
IPC: H01S3/097
Filed: 1986-06-27
Abstract: PURPOSE:To prevent reduction in laser output even though the rise and fall of a pulse are quickened, by a method wherein, with the provision of a pulse control unit to vary arbitrarily a base power, a laser oscillation threshold value is controlled during the pulse oscillation quiescent time in the pulse oscillation of the laser. CONSTITUTION:Discharge power of a laser oscillation threshold value or smaller is fed at the time of the interval part of a pulse oscillation waveform, that is, at the quiescent time of pulse oscillation. If a base power 4 is fed, the laser excitation of a discharge part is enhansed and the rise and fall characteristics of pulse oscillation are changed. That is the base power is made larger and changed in a direction A, that is, the rise and fall characteristics are sluggishly changed, and the base power is made smaller and changed in a direction B, that is, the rise and fall characteristics are abruptly changed and besides, the peak value of pulse becomes a constant value. Accordingly, by providing a device to vary the base power arbitrarily, the rise and fall characteristics of pulse of pulsed laser at the time of its oscillation can be easily made variable.
