Title: Method for sintering oxide magnetic material with high magnetic permeability
Inventor: GOTO TATSUFUMI
IPC: H01F1/34
Filed: 1994-06-28
Abstract: PURPOSE:To obtain the subject material at a low cost by laying on a sintered tile powder composed of ZnO and at least one kind of oxide selected from Fe2O3, MnO, Al2O3 and ZrO2 and ZnO, putting a meshy tile thereon, and then putting thereon an oxide magnetic material molded product consisting mainly of Fe2O3, MnO and ZnO, followed by sintering. CONSTITUTION:This sintering method comprises reducing developing internal stress through canceling the composition difference between the surface layer and inner layer of a molded form by preventing the Zn evaporation from the surface layer through controlling the atmosphere during evaporating the Zn through a meshy tile from the ZnO powder in the 2nd layer in the sintering process. Besides, by this method, contact between the molded form and embedded powder etc., can be avoided, preventing its deformation and also preventing the powder from scorching onto the sintered compact. In the figure, the 1st layer represents an Al2O3 tile, 2nd layer the powder 2 composed of ZnO and ZrO2 laid uniformly on the 1st layer, 3rd layer the meshy tile 3, and the molded form 4 is put on the tile 3, followed by sintering at 1400 deg.C for 2h in an oxygen- contg. nitrogen atmosphere.

Title: Picture reader and picture reading method
Inventor: TOMARU NAOSHI
IPC: H04N1/10
Filed: 1995-07-05
Abstract: PURPOSE: To suppress the temperature change of a read sensor, which occurs during prescribed time from a picture read start, to a minimum and to precisely read data even by a color picture reader. CONSTITUTION: A cooling fan 12 is rotated and an original irradiating lamp 2 and the read sensor 10 are cooled during the reading of a picture and during waiting. Air quantity from the cooling fan 12 is set to a maximum during the reading of the picture, and air quantity from the cooling fan 12 is reduced to the extent that a temperature rise by the self heat generation of the read sensor 10 is suppressed during waiting. Thus, the temperature of the read sensor 10 is maintained constant, and the fluctuation of the characteristics of the read sensor 10 is prevented. Air quantity from the cooling fan 12 can be adjusted by controlling operation voltage against a motor rotating the cooling fan 12 or arranging a movable air quantity adjustment board in the path of the air from the cooling fan 12.

Title: Pll circuit
Inventor: SEGAMI MASAHIRO
IPC: H03L7/081
Filed: 1996-07-01
Abstract: PROBLEM TO BE SOLVED: To improve the output jitter characteristic by giving a capacitor voltage to each delay element to control an entire phase difference of a variable delay line, so as to be one period of a reference clock thereby avoiding any discontinuous point and a dead-band of a phase comparator. SOLUTION: A tapped voltage variable delay line (hereinafter called delay line) 10 is made up of a series connection of a plurality of voltage controlled delay elements D0-D9. A phase comparator circuit 20 detects a phase difference from signals between taps of the delay line 10 and provides outputs of a phase lead output and a phase lag output. An output of an OR gate C4 has a specified pulse width, when the phase difference in the delay line 10 just corresponds to one clock period, and the pulse width is changed in an opposite relation to an output of a gate B9. Thus, an ideal linear feedback is applied at a lock point, and an output clock with very small jitter is obtained.

Abstract: PURPOSE:To prevent the level of an image signal from varying owing to air or water feeding operation by providing a dimming control means which maintains a last dimming state in an air or water feeding period in synchronism with the air or water feeding operation. CONSTITUTION:The electronic endoscope device is provided with the means which maintains a dimming state based upon a photometry or dimming signal before air or water is fed actually from an air or water feed nozzle during the air or water feeding period according to a timing signal for the air or water feeding operation. In this case, when an air or water feed switch 16 is turned off after being turned on, the switch of a photometry circuit 33 is turned on. Therefore, the photometry circuit 33 starts the photometric operation with an image signal and the numerical aperture of a diaphragm 25 is controlled through a stop control circuit 24 with the output signal of the photometric operation, thus performing automatic dimming operation so that the image signal level becomes optimum. Consequently, even when the air or water is fed while an object image is observed, the variation in the image signal level corresponding to the object image can be suppressed.

Title: Premixing burner and method of operating it
Inventor: DOEBBELING KLAUS DR
IPC: F23C7/00
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To additionally stabilize a flame without raising the amount of emission of harmful substances not so much by disposing a plurality of holes in a burner sickle-shaped plate, and using these holes for supplying a gaseous fuel to an outside recirculating zone. SOLUTION: A row of holes 27 are disposed within the range of a burner sickle-shaped plate 26, for example parallely to an axis 22 of a burner. These holes 27 serve to supply additional gaseous fuel to an outside recirculation zone and mix it thereinto. Operation is performed in such a manner that only about 3 to 8% of the gaseous fuel reaches the outside recirculation zone through the holes 27. Herein, cooling air has been already added and part of heat capable of being sensed by the recirculated gas is already dissipated to a front plate, so that the additional fuel addition does not raise NOx emission so much. Thus, a flame is additionally stabilized.
