Patent JP-H0482289-A (JP)
Title: Semiconductor laser
Inventor: KINOSHITA JUNICHI
IPC: H01S5/12
Filed: 1990-07-25
Abstract: PURPOSE:To enable the smooth far vision field images to be produced by a method wherein the vertical trenches to waveguide stripes are formed in the buried regions near both ends. CONSTITUTION:Within a distribution feedback type semiconductor laser, the vertical trenches 40 to waveguide stripes are formed in the buried regions near both ends. These trenches 40 are formed by excavating the patterned parts of the trenches 40 deeper than the waveguides 13 using ion-milling process. At this time, the radiated mode beams emitted halfway by the laser waveguides 13 are reflected on the trenches 40 as if checked thereby not to reach the output ends. Accordingly, the far vision field images are smoothed without interfering with the output beams. Through these procedures, the interference of the radiated mode beams from the part wherein the refractive index of the waveguides is notably fluctuated with the output beams emitted from the output ends is avoided thereby enabling the smooth far vision field images to be produced.

Title: Control of printer
Inventor: OSUGA HIROSHI
IPC: B41J29/38
Filed: 1989-07-27
Abstract: PURPOSE:To prevent the printing of data unnecessary to print and to immediately bring a computer and a printer to a printing completion state by holding an interface to a READY state while a reset switch is closed and not printing the data transmitted during this time. CONSTITUTION:Data is sent to a printer 1 from a computer 3 through an interface 4 at the time of printing. When the printing of the data in the computer 3 is desired to be stopped on the way, the reset switch 6 of the printer 1 is closed. Whereupon, the interface 4 becomes a READY state and the computer 3 confirms this state to transmit data to the interface. At this time, the printer 1 does not print the transmitted data and printing function is reset. As mentioned above, during a time when the reset switch 6 is closed, the interface 4 is in a READY state and the printer 1 does not point the data transmitted from the computer 3.

Title: Pulverized coal burner
Inventor: MASAI TADAHISA
IPC: F23D1/04
Filed: 1982-11-09
Abstract: PURPOSE:To effect most suitable combustion of even pulverized coal having a high fuel ratio, by a method wherein a passage for conveying pulverized coal with the aid of a primary air and a primary nozzle open to the inside of a furnace at the forward end of the conveying passage are divided into plural pieces. CONSTITUTION:A pulverized coal burner according to this invention consists of a primary nozzle, comprising a split primary nozzle 10 for injecting coal of low fuel ratio and a split primary nozzle 11 for injecting coal of high fuel ratio, a secondary air nozzle 12 communicated to a secondary resistor 8, and a tertiary air nozzle 13 communicated to a tertiary resistor 9. Pulverized coal 4 of a low fuel ratio, conveyed through a conveying pipe 60 togetherwith a primary air, is injected into a furnace through the split primary nozzle 10 after passing through an inner conveying passage 6, and is immediately evaporated and fired to start combustion. Meanwhile, pulverized coal 5 of a high fuel ratio conveyed through a conveying pipe 70 is injected into a furnace through the split primary nozzle 11 after through an outer conveying passage 7, but the coal is rapidly heated by the influence exercised by the combustion flame of the pulverized coal of the low fuel ratio to quickly start combustion. This stabilizes the flame and maintains it at a high temperature, and enables sharp reduction in the production of a unburnt content in resultant ash.

Title: Foreign matter inspection system
Inventor: KANZAKI TOYOKI
IPC: H01L21/66
Filed: 1996-07-06
Abstract: PROBLEM TO BE SOLVED: To discriminate between a pattern and a foreign matter surely without intensifying a light source or enhancing the sensitivity of a detector by varying the scanning speed of laser light using a scanning mirror depending on the detection accuracy. SOLUTION: Total quantity of scattering light Ip per unit time being obtained when a foreign matter having size DP on a substrate 1 to be inspected is scanned at a speed (v) by means of a scanning mirror 7 using a laser light L having quantity of incident light DL per unit time and a beam diameter DL is represented by a formula; Ip =A.I.(DP+DL)/v (where, A is a set of constants including the condensing solid angle of a photodetector 13 and the scattering cross-sectional area of a foreign matter). According to the formula, the total quantity of scattering light Ip per unit time from the foreign matter is doubled when the scanning speed (v) is halved and the total quantity of scattering light Ip is halved when the scanning speed (v) is doubled. Scanning is performed at high speed for high sensitivity inspection and at low speed for low sensitivity inspection.  Consequently, a foreign matter can be inspected at optimal detection sensitivity and detection speed.
