Title: Sintered parts
Inventor: YAMADA HIROSHI
IPC: C23C8/22
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To provide a sintered parts with the wear resistance of a surface and the inside strength. SOLUTION: A sintered parts is prepared by forming and baking metal powder under the condition of 0.20-1.00% in initial carbon concentration and 7.20-7.50 g/cm3 in initial forming density. The sintered parts are decarburized to form a decarburized surface layer portion 18 in which the carbon concentration is lower than the initial value only for the surface layer portion. Then, the sintered parts is subjected to the pressing such as roll forming. In the pressing, the density is intensively improved at the surface layer portion 18 to form the decarburized surface layer portion 18 whose density is higher than the initial forming density and close to the true density, and whose carbon concentration is lower than the initial value, and an inner portion whose density is substantially the initial forming density, and whose concentration is the initial carbon concentration.  The density of the decarburized surface layer portion is improved to 7.60-7.80 g/cm3. The surface layer portion of excellent carbon concentration at the surface can be formed by carburizing and hardening the sintered parts.

Title: Current control type variable frequency oscillator
Inventor: IKEDA HIROSHI
IPC: H03B5/18
Filed: 1985-03-05
Abstract: PURPOSE:To improve the purity of signal and to attain broad band by using a magnetic substance resonator whose resonance frequency is changed by a magnetic field as a component and to prevent noise characteristic or the like from being affected by the change in the oscillating frequency. CONSTITUTION:The magnetic substance resonator 1 whose resonance frequency is changed by a magnetic field H is used as a component. Thus, the relation between the purity of signal and the band width is lost and since the Q of the resonator 1 and the variable range of the resonance frequency are large, the purity of signal is improved and the band width is large. Since the admittance of the resonator 1 due to the change in the strength of the magnetic field H is almost unchanged, the admittance of the oscillator is unchanged and the noise characteristic is also unchanged.

Reference voltages +E and -E from first and second reference voltage sources 23 and 24 are applied to the other input terminals of the comparators 21 and 22. The first comparator 21 outputs an H level when the driving-current value in the positive direction becomes the reference value or higher. The second comparator 22 outputs an H level when the driving-current value in the negative direction becomes the reference value or higher. A logic circuit 27 receives the results of the comparisons outputted from the first and second comparators 21 and 22 and outputs a logical OR.

Abstract: PURPOSE:To transmit time casting sound only to a specific user by a relatively small apparatus by generating a plurality of primary ultrasonic waves different in frequency and outputting audible sound having directionality by the interference of those primary ultrasonic waves. CONSTITUTION:When a signal forming part 6 receives an information signal from a clock part 5, the signal forming part 6 applies the modulation due to an audible signal of frequency Fm to a carrier wave signal of an ultrasonic wave of fundamental frequency Fo to input signals of frequency bands Fo+Fm/2 to a sound source 1. Primary sonic waves being ultrasonic waves of frequency bands Fo+Fm/2 are outputted from the sonic source 1 and a secondary sonic wave having audible frequency Fm is generated in a sound guide pipe 4 by the interference (parametric effect) of the primary sonic waves. This secondary sonic wave has high directionality similar to the primary sonic waves and changes in its direction by a reflecting surface 7 to be sent out to the outside from an aperture part 3. During this time, the secondary sonic wave is attenuated in its side lobe by a sound absorbing material 8 to hold high directionality and the primary sonic waves are also attenuated by the sound absorbing material 8 and limited from the send-out to the outside of a housing 2 by a filter 9 without obstructing interference effect.
