Title: Ion source, neutral particle beam injection device for nuclear fusion, and ion beam process device
Inventor: TANAKA MASANOBU
IPC: H01J37/08
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To enhance the ion extraction efficiency by restraining the divergence of an ion beam even if the strength of electrode material is increased through an increase in the thickness. SOLUTION: During irradiation of a negative ion beam 6, a boundary area S between the surface of a plasma electrode 1 and a plasma in a discharge chamber 4 is shifted in a beam extracting direction because the inclined surface 1b of the plasma electrode 1 is provided, and the distance from the boundary face B of the plasma 5 and the ion beam 6 to an extraction electrode is decreased at d2, so that an electric field for extracting the negative ion beam 6 can be intensified, with the result that even if the thickness of the electrode 1 is increased, the divergent angle of the negative ion beam 6 is restrained from increasing to make it possible to prevent the negative ion beam 6 from colliding against the next extraction electrode and an accelerating electrode.  Moreover, when the inclined face 1b is provided at the peripheral edge of an extraction hole 1a, negative ions N produced on a surface are ejected in the direction of the beam extraction hole 1a and positively extracted from the extraction hole 1a of the plasma electrode 1 whereby the efficiency of extracting the negative ions N is enhanced and the development of the negative ion beam 6 into a large current can be achieved accordingly.

Abstract: PURPOSE:To prevent the fouling of a laser tube, and to lengthen the lifetime of the laser tube while miniaturizing the laser tube by closing shutters disposed on the fronts of laser mirrors at both end sections of the laser tube when the operation of a device is stopped. CONSTITUTION:Branch sections 21, which are crossed at right angles with a laser tube 1 and communicated with the discharge space of the laser tube and both ends of which are closed by hollow round bars, are shaped onto the fronts of laser mirrors 2 at both end sections of the laser tube 1. Movable pistons 22 fast stuck onto the inwalls of a hollow sections in the branch sections 21 are installed into the hollow sections.

When a power supply 10 is turned ON, coils 25 are excited and magnetic force is applied to metals 24, the pistons 22 are driven to the positions of top dead centers, and laser beams can be passed. When the power supply 10 is turned OFF, the coils 25 are deenergized, the pistons 22 are dropped by their own weight, the laser tube 1 is closed, and metallic vapor is confined at the central section of the laser tube 1.

Title: Production of polycrystalline silicon
Inventor: KOMATSU YOSHINORI
IPC: C01B33/02
Filed: 1992-10-15
Abstract: PURPOSE:To prevent the clogging in the piping of a waste gas line and the inner leakage of a valve by adhesion of fine powder silicon and to effect reaction stably over a long period of time by forming the above piping of a conductive material and grounding the piping. CONSTITUTION:Seed silicon particles having 50 to 300mum average grain sizes are packed from an introducing pipe 10 into a fluidized bed reactor 1 and are held at 600 to 1100 deg.C by a heater 8 for heating. A diluting gas and a silane compd. are introduced into this reactor from a gaseous raw material introducing pipe 9 to deposit the thermally decomposed silicon on the silicon particles. A part of the silane compd. turns to the fine powder silicon which is entrained by waste gases to jump out of the reactor. This fine powder silicon is passed through the waste gas line 4 and the valve 5 and is captured by a filter 6. The piping of the waste gas system is made of a conductive material (e.g.: stainless steel) and is kept grounded by a grounding line 7 for static-proof. The seed silicon particles are added and the height of the fluidized bed increases on progression of the reaction and, therefore, the the particles are partly withdrawn from a withdrawal pipe 11, by which the specified height of the fluidized bed is maintained.

Title: Image signal recorder
Inventor: YASUMURA HIROTO
IPC: H04N9/84
Filed: 1987-11-30
Abstract: PURPOSE:To reduce the cost of the title recorder by generating two subcarrier signals, which have the same frequency and have prescribed phase relations, to simplify a phase shifting circuit required for recording processing. CONSTITUTION:Switching control is always performed for each horizontal synchronizing frequency fH at the time of PI processing, and the switching control is performed for each frequency fH in case of recording of a N-th track and is performed for each fH/2 in case of recording of a (N+1)th track at the time of PS processing. Since the phase difference of integer multiple of 90 deg. is only required between subcarriers after PS/PI processing and NTSC/PAL processing, frequency signal 2fL and fL are subjected to logical processing to simultaneously generate two required low-band subcarrier signals fL1 and fL2. Thus, phase shift for recording processing and that coping with the television system are simultaneously performed to simplify the constitution.
Patent JP-H02148775-A (JP)
Title: Optical sensor
Inventor: NAGAOKA JIRO
IPC: H01L31/12
Filed: 1988-11-29
Abstract: PURPOSE:To reduce connecting positions, to improve reliability and to decrease its cost by providing a light emitting element, a photodetector connected in series with the element, and a resistor connected in parallel with the photodetector. CONSTITUTION:Since a current from a light emitting diode 11 flows in series with a resistor 15 and a resistor 22 in a state that a light from the diode 11 docs not enter a photo-transistor 12, it becomes relatively small, and the voltage V1 of a terminal A becomes V1=[(V00-VF)/(R15+R22)]XR22, where VCC is the voltage of a DC power source 21, VF is the forward drop voltage of the diode 11, R15 is the resistance value of the resistor 15, and R22 is the resistance value of the resistor R22. When the light of the diode 11 enters the phototransistor 12, the phototransistor 12 can be sufficiently saturated by suitably selecting the resistance values of the resistors 15, 22. The voltage V2 of the terminal A in this case becomes V2=VCC-VF-Fsat, where Fsat is the collector-emitter saturated voltage of the phototransistor 12.
