Title: Manufacture of plasma display panel
Inventor: SANO YOSHIO
IPC: H01J11/50
Filed: 1991-08-06
Abstract: PURPOSE:To enable easily coating a phosphor onto the substrate surface and partition side surface constituting a picture element in a color plasma display having a partition. CONSTITUTION:Using a screen 1 having an opening 2, a phosphor paste 4 is forcibly pressed in through this opening 2. A phosphor film 17 is thereby formed on the side surface of a partition 16 as well as the face of a substrate, both constituting the inner wall surfaces of a picture element. Since the opening 2 of the screen 1 may be smaller in size than the picture element, even if displacement in position of the screen 1, or expansion and contraction thereof, somewhat occurs, it is possible to easily form the phosphor film on the bottom surface and both the side surfaces in the object picture element. Separate coating of three-colored phosphor also is easy.

Title: Refractory mortar for continuous casting
Inventor: INDO HISAHIRO
IPC: C04B35/66
Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To obtain a refractory mortar enhanced in corrosion resistance by grinding a refractory containing alumina and carbon in a specific weight ratio and subsequently compounding the obtained powder having a specific particle diameter or less with a plastic clay in a specific ratio. SOLUTION: This refractory mortar is obtained by kneading >=70 wt.% of alumina, >=10 wt.% of carbon and a proper amount of a binder such as polyvinyl alcohol, press-molding the hneaded product, calcining the molded products, grinding the obtained blocks to prepare the powder having particle sizes of <=0.5 mm, and subsequently kneading 40-80 wt.% of the calicined powder with water and a plastic clay corresponding to SK38 to form the refractory mortar. When the particle sizes of the ground blocks exceed 0.5 mm, the extensivity of the mortar is lacked, and local pores are caused, because the joints of refractories are 3-5 mm. When the content of the powder obtained by grinding the calcined blocks is <40 wt.%, the refractoriness and infiltration resistance of the mortar are deteriorated.  When the content of the powder exceeds 80 wt.%, the extensivity of the mortar is lost, and the amount of water to be added is increased, thus lowering the chargeability of the mortar into the joints.

Title: Electrostatic latent image recorder
Inventor: YOKOI KATSUYUKI
IPC: G03G21/00
Filed: 1990-07-23
Abstract: PURPOSE:To prevent the local excess electrification of a rotary drum and fatal damage caused by the degradation of the property of the rotary drum and a dielectric breakdown by detecting the rotation of the rotary drum and interrupting the output of a corona discharger. CONSTITUTION:When a motor 24 is rotated at constant speed, a rotation detecting circuit 28 outputs a control signal 29 to carry out an action so that a high voltage power source control circuit 31 applies a high voltage to a transfer electrifying unit 20 with a signal 32 from a CPU 35 at prescribed timing set in advance. When the motor 24 is stepped out and its rotation is stopped, the step-out of the motor 24 is judged from a rotation synchronizing signal 27 on the rotation detecting circuit 28, and the output of a high voltage power source circuit is stopped with a control signal 30 regardless of the signal 32. Thus, even if the rotary drum driving motor 24 is stepped out, the deterioration of the rotary drum is prevented.

Filed: 1982-11-11
Abstract: PURPOSE:To improve the degree of integration, and to reduce a latch-up phenomenon by thinning the thickness of the epitaxial layer of the Bi-CMOS semiconductor device. CONSTITUTION:n<+> Buried layers 2 are formed under p channel MOS transistors and a p<+> buried layer 3 under an n channel MOS transistor, and both the base regions of a parasitic n-p-n transistor 16 and a parasitic p-n-p transistor 18 are formed in structure in which impurity concentration is high, thus inhibiting the hFE of these parasitic bipolar transistors to low values. The n<+> buried diffusion layers 2 lower resistance 19 between the base and emitter of the parasitic p-n-p transistor 18, and make said parasitic p-n-p transistor 18 difficult to be turned ON. Likewise, the p<+> buried diffusion layer 3 lowers resistance 17 between the base and emitter of the parasitic n-p-n transistor 16, and makes said parasitic n-p-n transistor to be hardly turned ON.

Title: Semiconductor laser
Inventor: KONNO NOBUAKI
IPC: H01S5/00
Filed: 1988-08-06
Abstract: PURPOSE:To prevent transverse spreading of injected current and to enable laser oscillation at a low threshold value by selectively etching an upper clad layer as far as an active layer in a shape of a ridge and by burying the ridge with a block layer so that the block layer comes into contact with the active layer. CONSTITUTION:At least an upper clad layer 5 of the upper clad layer 5 and a lower clad layer 3 is selectively etched so that it is left in a ridge. The ridge is buried with a high resistance block layer 7 whose forbidden band width is larger than the active layer 4 so that the block layer 7 comes into contact with the active layer 4 and the forbidden band width of the block layer 7 is made larger than that of the active layer 4 to realize a high resistance. Since the upper clad layer 5 is not provided as far as the active layer in the outside of the striped ridge of the upper clad layer 5, the outside of the ridge is covered with the block layer 7 of a high resistance. Transverse spreading of injected current is thereby controlled, thus realizing good laser oscillation through current concentration at a low threshold value.

Then, light is varied in the wavelength applying a pulse with a known peak value by a pulse generator 18 and received with a photodiode 20. Variation of transmission during the application of voltage is determined depending on the quantity of light received and thus, a variation of refraction is obtained from a relationship previously determined between the variation of transmission and variation of refractive index.
