Title: Secondary combustion method for gaseous co in oxygen bottom blowing converter
Inventor: KONDO HIROSHI
IPC: C21C5/30
Filed: 1986-06-27
Abstract: PURPOSE:To advantageously carry out a secondary combustion of gaseous CO in a converter and to prevent the erosion of the internal refractory of the converter by setting a tuyere for secondary combustion at the central part of the bottom of the converter and blowing gaseous oxygen at a regulated rate. CONSTITUTION:One or more tuyeres for secondary combustion are set at the central part of the bottom of a converter besides a bottom blowing tuyere for refining. Gaseous oxygen required to burn gaseous CO generated in the converter is blown from the set tuyeres at such a rate that gaseous oxygen can pass through a molten metal bath to burn the generated gaseous CO. Thus, the erosion of the inner refractory wall of the converter is inhibited and the amount of dust and spit can be reduced.

Title: Imaging device
Inventor: SHINPO TOSHINAO
IPC: G02F1/133
Filed: 1985-07-08
Abstract: PURPOSE:To reduce the cost of an imaging device and to perform fast printing and high-quality printing by making light guides correspond to a liquid crystal panel where (n)X(m) transparent eletrodes are arrayed in a matrix and arraying their end parts linearly on the side of a photosensitive body. CONSTITUTION:Liquid crystal is charged between two substrates where scanning electrodes 53 and signal electrodes 54 to form the matrix part 50 which has (n)X(m) shutters, and end surfaces 61 of the light guides corresponding to the respective shutters are put in a line opposite the photosensitive body. A signal is sent to a terminal Xj for selecting a column and a sequential scanning signal is sent to a terminal Yi for selecting a row; when one cycle writing is performed, the photosensitive body is rotated by one-dot pitch. Therefore, only (n+m) shutter driving elements are required to reduce the cost greatly and the on-off ratio of the quantity of transmitted light because of the memory property of the liquid crystal. Then, light is irradiated in a short time to perform fast printing and high-quality printing with high dot density is performed because the density of light guide end parts is improved.

Title: Semiconductor light receiving system
Inventor: NAGAI HARUO
IPC: H01L31/107
Filed: 1979-11-19
Abstract: PURPOSE:To prevent a carrier recombination and leakage and to obtain a high quantum efficiency by a method wherein a salient part is installed on an N<+> type substrate surface and an N layer is laid thereupon, then, the whole surface is coated and the N layer is installed and a P layer is selectively installed striding over the salient part. CONSTITUTION:An N epitaxial layer is laid upon an N<+> type substrate and applying a mask 71, it is etched to form N layers 26, 28. Next thereto, an N layer 29 is formed in an epitaxial growth, thus completing a basic body 31. The mask 71 is removed and applying an SiO2 mask 37, a P layer 40 is formed and electrodes 38, 39 are formed. Lattice constants of an N layer 30 including layers 28, 29, the N layer 26 and the N<+> substrate are made approximately equal and a forbidden band gap of the N layer 26 is made narrower than those of others, thus, the N layer is made substantially a photosensitive layer. On this account, on the light receiving surface 27, recombination of carrier or a leak current are hardly generated. In this way, in comparison with the existing system, a light receiving system having a sharply higher quantum efficiency is obtained.

Title: Apparatus for inspecting cathode-ray tube
Inventor: KUSAKA KUNIHIKO
IPC: G01R31/24
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To shorten the time required for inspection by stopping the application of an anode voltage in a driving state under the control of a control circuit, inspecting gas ratio, setting a normal operating state, and outputting an image for the inspection. SOLUTION: A slat cathode-ray tube 5 is set to a jig and a switch 26 is turned on. A system control 52 supplies a normal driving power source from a power spruce circuit 51, thereby, the cathode-ray 5 is set in a normal image output mode. Then, the switch 26 is depressed and the circuit 51 supplies the driving power source necessary for inspecting a gas ratio. While the application of an anode voltage to the cathode-ray tube 5 is stopped, a current in the tube is measured by an ammeter device 3 and a degree of vacuum is measured. In response to the measurement result from the device 3, the control 52 sets the cathode-ray tube 5 again in an image output inspection mode. When the image output is detected to be correct, the cathode-ray tube 5 is switched to a stray inspection mode and consequently turned OFF. An electron gun is confirmed while a high anode voltage is impressed to the cathode-ray tube, when a sequence of inspections is completed.

Filed: 1990-06-11
Abstract: PURPOSE:To improve the of riding comfortableness by adding a load unbalance signal and a cage internal load signal at both sides of a cage and a balance weight being outputted by a compensation means, thereby making load unbalance torque at both these cage and balance weight sides so as to be produced in a cage drive motor. CONSTITUTION:A cage position arithmetic unit 8 operates the current position of a cage on the basis of a speed signal wr out of a speed detector 7. On the other hand, a speed control arithmetic unit 10 outputs a torque command Te on the basis of a difference between a command wp and the detection speed signal wr. A compensator 11 calculates the unbalance of a rope portion from the current position of the cage and the torque command Te, adding it to this torque command Te with an adder 12. In addition, with the result, a cage internal load detecting signal being outputted by a weighing instrument 2 is added by another adder 13. In consequence, an inverter unit 14 outputs a final torque command to an electric motor 6.

Patent JP-S5967772-A (JP)
Title: Laser recorder
Inventor: MATSUMOTO KOUZOU
IPC: G02B26/12
Filed: 1982-08-31
Abstract: PURPOSE:To compensate the variation of light emission in long term due to such as environmental temperature change and secular deterioration of laser and also the variance in the reflecting factor at each reflecting plane of a rotary polygon mirror, by controlling independently at each reflecting plane the intensity of a beam scanned with the rotary polygon mirror. CONSTITUTION:A peak hold circuit 301 is set with an output pulse PC just before an analog signal BD is generated in the scanning of a reflecting plane, the scanned luminous amount is detected with a peak value of the analog signal BD generated just after, and the result is sampled and held in any of sample- and-hold circuits 305-312 just before the end of scanning. The value sampled this time is not reflected at the scanning just after, that is, the scanning due to adjacent reflecting plane but reflected at the scanning of the same reflecting plane after the rotary polygon mirror turns once. The operation like this is repeated independently of each reflecting plane. As a result, the control of scanning luminous amount is attained entirely independently of the mutual interference between the different reflecting planes, and even if the reflecting factor is different at each reflecting plane, the scanning luminous amount on the photoreceptor is kept suitably at all times.

Next a concave part is formed by etching the epitaxial layer 3 in the separating region, and channel checking diffusion is provided and then the concave part is oxidized in order to form a separated oxidized layer 8. At the same time, an oxidized film 8a is allowed to intrude into the lower part of the nitrified film 5. Then the nitrified film 5 is removed and the region 15 insufficiently intruded by the oxidized film is again oxidized and made flat. After this, a window is made in the oxidized layer 8a to form, for instance, an element such as a transistor. By so doing, isoplanar structure with high density can be formed without crystal defect.
