Title: Gas discharge display device
Inventor: YOSHIOKA KAZUO
IPC: G09G3/28
Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To make it possible to decrease the fluctuations in light emission intensity when there is writing in another line by making the crest value of the writing signal for starting an electric discharge impressed on a column line or row line and the crest value of a maintenance signal nearly the same. SOLUTION: The crest value of the writing signal Xwp applied on one electrode of a fluorescent lamp is made nearly the same as the crest value of the maintenance signal Xsp applied on the electrode. Namely, the crest value of the writing pulse Xwp and the crest value of the maintenance pulse Xsp are the same and, therefore, a difference does not arise in comparison of the voltage between the X-Yi lines when the row line Yj is scanned, i.e., in the period [2] and the voltage between the X-Yi lines when the row line Yk is scanned, i.e., in the period [3]. Consequently, the difference in the intensity between the discharge generated in the period [2] and the discharge generated in the period [3] is lessened and the change in the light emission luminance generated by the writing in another line is lessened.

Title: Drive circuit for light emitting element
Inventor: HIRANE HIDEO
IPC: G09G3/14
Filed: 1987-05-13
Abstract: PURPOSE:To eliminate the fluctuation of an optical output of a light emitting diode array by using a digital signal to control the output current of a drive circuit driving the light emitting element in multiple stages. CONSTITUTION:Constant current control utilizes a current mirror circuit comprising a bipolar transistor TR0 functioning as a reference component and a bipolar TRC functioning as an output component. Reference currents I0-In for controlling the output current are given by a digital current control signal, which is of n bits and the reference currents I0-In corresponding to each bit differ from each other and the output current is specified by the sum of the said reference currents I0-In. The n-bit current control signal gives 2n-way of reference currents I0-In and the output current is controlled in 2n stages of the same number. Thus, the drive current correcting the optical output dispersion of the light emitting diode array LED is found out easily from the control range. Thus, the unevenness in optical output is suppressed lower.

Title: Gap ball mill for continuous fine dividing
Inventor: GEERUHARUTO BIYUURERU
IPC: B02C17/16
Filed: 1988-05-13
Abstract: Three mill units are mounted axially in series in a mill housing with a cover. Each mill unit has a rotor disc between two stator discs. The rotor discs are secured to the rotor shaft at their radially interior region. The stator discs are secured to the housing wall at their radially outer region. Individual pulverization gaps are formed between the stator discs, which gaps run around the rotor discs and in longitudinal cross section extend sequentially with a serpentine shape. The outer parts of the pulverization gaps form individual gap loops the inner ends of which are connected or "short-circuited" via ball return channels. During operation, the grinding elements are accelerated outward by centrifugal forces, and are concentrated into the gap loops. The grinding elements in each of the individual stages may be kept separated from the grinding elements in other stages; and they may have different sizes from stage to stage. The individual mill stages can be replaced as units. Alternatively, the rotor discs and stator discs which are rotationally symmetric can be replaced individually. They can have different axial cross sections, containing a single bend or multiple bends. The processing pressure for the material being pulverized which is passed through the serpentine pulverization gap system can be set accurately based on the rotational speed (rpm), so that microorganisms are recovered without the hyaloplasm leaking out or being worked into (i.e. intermixing with or being forced into intercalation with) the other materials.

Title: Light transmissive member
Inventor: TAKAI YASUSHI
IPC: H01J5/04
Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To obtain a member hardly corroded by gaseous halogen, etc., capable being sintered at relatively low temperature and useful in a light tube of a discharge lamp by using a light transmissive sintered compact having a garnet structure shown by a specific composition and having specific surface roughness, porosity and light transmissivity of visible rays. SOLUTION: The light transmissive member is the sintered compact having the garnet structure shown by the general formula Ln3Al5O12 (wherein Ln is at least one of Dy, Ho, Ym, Yb and Lu), below 1 μm surface roughness (Ra), below 1% porosity and over 50% light transmissivity of visible rays. The crystal particle size hardly affects on corrosion resistance but affects on the mechanical strength necessary when the sintered compact is used as the member. When the crystal particle size is >=30 μm, the mechanical strength is extremely lowered. Therefore the sintered compact having <=30 μm crystal particle size is preferably used.  This sintered compact is obtained by using powder having <=2 μm average particle size as a starting material, compacting the starting material by a powder compacting method and a strip casting method and sintering the compact under a vacuum or gaseous hydrogen atmosphere.
