Abstract: PURPOSE: To manufacture a top layer having uniform constituent distribution by compressing and cohering together tungsten power with a first pressure which does not destroy the tungsten powder too extensively, followed by coating with a top layer of Sc2 O3 powder, and compressing the whole assembly with a second, high pressure to destroy the powder to a substantial degree. CONSTITUTION: A cavity in a holder 2 of a press 1 is filled with tungsten powder 9 and shaken several times to have the space between two dies to promote homogeneity filled and adhesion of the powder or pressed formed body. Next, a force F is applied to the die 3 to compress the tungsten powder 9, or a force F1 of at least 1×10<7> to 8×10<7> pa, which is sufficient to form a cohesive body 10 but of such a magnitude that substantially destroys powder particles. The top layer is applied using a brush, for example. Hydrogenated scandium or other scandium compound is used as an emission inducing material added to the tungsten powder. Here, a force F2 is applied to the whole assembly through the die 3, to obtain a compression formed body 12.  This provides an average particle diameter of tungsten powder in effect in the range of 20 to 150 micrometers with the powder crushed to a considerable degree.

Filed: 1981-10-15
Abstract: PURPOSE:To obtain an excellent atomizing performance of low power consumption by means of a compact structure, by exciting a liquid in a pressure chamber and a nozzle by electric vibration. CONSTITUTION:When AC voltage is applied to a piezoelectric element 45, the piezoelectric element 45 expands and contracts in the diameter direction by a piezo-effect, and a nozzle part 44 and a nozzle 43 vibrate. By this vibration, increase and decrease of pressure of frequency corresponding to AC voltage are generated in a pressure chamber 41, internal pressure of the pressure chamber 41 rises at the time of a positive semi-cycle, and liquid drops of a microscopic and uniform particle diameter are discharged from the nozzle 43. Subsequently, when negative semi-cycle voltage has been applied, pressure in the pressure chamber 41 decreases, but surface tension of kerosene works on the nozzle 43, and inflow of air from the nozzle 43 is obstructed. Since the nozzle 43 is excited by the piezoelectric element 45, kerosene in the pressure chamber 41 and the largest part of vibration acceleration of the nozzle part 44 are placed in the vicinity of the nozzle 43, by which generation of foams is prevented.

IPC: H01J9/50
Filed: 1988-06-30
Abstract: PURPOSE:To enable to recover a reusable shadow mask without cleaning by introducing the mixed gas of the controlled content of O2, Co2 and H2O in breaking the vacuum of a cathode ray tube. CONSTITUTION:In breaking the vacuum of a defective cathode ray tube, the mixed gas of O2, CO2 and H2O is introduced. This mixed gas is controlled in its composition such as to convert the getter metal attached to a shadow mask 3 rapidly into BaCO3, that is, as BaCO3 does not have an adverse effect even if it remains on the shadow mask 3 to be reused, it converts rapidly Ba on the getter metal surface into BaO, then into BaCO3, and protects BaO created in the getter metal interior from moisture by means of the BaCO3 layer of the surface so as to prevent the conversion into Ba(OH)2. As a result, a shadow mask can be recovered efficiently without cleaning as well as the cost can be reduced.

Title: Knocking detector for internal combustion engine
Inventor: OOTSUKA YOSHINORI
IPC: F02D45/00
Filed: 1982-09-21
Abstract: PURPOSE:To improve knocking detecting property, by controlling a current, which is supplied to the exciting coil of a knocking detector in response to the operating state. CONSTITUTION:A DC voltage Vin, which is proportional to the number of rotation, from an engine state detector 7 is connected to an inverted input terminal 35a of a differential amplifier circuit 35. A voltage Vref, which is sufficiently higher than the voltage Vin, is applied to a positive input terminal 35b as a constant reference voltage with respect to the number of rotation. The output of the differential amplifier circuit 35 becomes an output Vout, which is proportional to Vref - Vin. The voltage Vout is converted into a current by a voltage-current converter 36, and the current is supplied to an exciting coil 22 of a knocking detector 2. When the number of rotation is increased, the exciting current is decreased. Therefore, the noise level of the output of the knocking detector is kept approximately constant. The judgment of the knocking is made as follows: the output of a detecting coil 25 is integrated by an integrating circuit 32 through a filter circuit 31, and the result is compared with the direct output of the filter circuit 31 in a comparator circuit 33.

Accordingly, a stable perfect single mode is acquired. When the reflectivity of the end surface of one resonator is elevated up to a value close to 1 for lowering a threshold and increasing an output, a means for further improving performance is obtained.

Title: Method and apparatus for detecting stress
Inventor: HIRASAKI SHIYUUICHI
IPC: G01L5/04
Filed: 1980-11-26
Abstract: PURPOSE:To permit a proper detection of stress independently of the change in moving speed, by disposing a detection coil so as to be offset with respect to the moving locus of a strip magnetic substance passing right above an excitation coil. CONSTITUTION:By inclining an iron core 40 of an L-shaped detector at a given angle theta1 (e.g., 15-30 deg.) with respect to the rolling direction (moving direction) of a rolled steel plate, a rolling direction detecting coil 46 is disposed so as to be offset more than 1/2 of the magnetic pole width(b) of the iron core 40 along the width direction of the rolled steel plate with respect to the moving locus B of the rolled steel plate passing right above the center of an excitation coil 44, and also an iron core 42 disposed along the width direction of the plate is inclined at a given angle theta2 with respect to the plate width direction. Thereby, the residual magnetism of the rolled steel plate excited by the excitation coil 44 never passes right above the detecting coil 46 and consequently the voltage induced in the detecting coil 46 is hardly affected by the rolling speed. Accordingly, it becomes possible to perform a proper detection of stress.
