Title: Metal matrix composite body
Inventor: SCHMITT THEODORE NICOLAS
IPC: C22C47/08
Filed: 1999-01-08
Abstract: PROBLEM TO BE SOLVED: To provide a metal matrix composite body showing a low thermal expansion coefficient which matches that of AlN and Si by forming a reinforcing material from a recrystallized silicon carbide. SOLUTION: As the reinforcing material for a metal matrix composite body, a recrystallized silicon carbide (RSiC) of 5-40 vol.% porosity (2-30 vol.% is preferred) is used. The original material of the RSiC is SiC powder having 2-mode particle distribution, and one side is a particle 20 of relatively large particle size (about 100 μm) while the other side is a particle 21 of very small particle size which reaches micron range (particle size <1 μm), with the small particle 21 made to be confine in the gusset of the large particle 20. Then it is sintered at 2,200 deg.C or higher in an inert gas atmosphere. Thus, it is manufactured with no contraction, without tightening of pores among large particles. With the use of different porosity, a thermal expansion coefficient is also adjusted very accurately.

Title: Magneto-optical disk reproducing system
Inventor: HORIGOME HIDEYOSHI
IPC: G11B11/105
Filed: 1987-01-12
Abstract: PURPOSE:To improve the read-out accuracy and also to prevent the deterioration of recording information by controlling laser beam to be radiated, so as to intermitted in a period higher than at least the sample rate of information, so that the non-irradiation time becomes longer than the irradiation time. CONSTITUTION:For instance, when a clock period is t0 (100ns), the pulse width of a pulse LP is set to about 20ns-5ns by setting it to its 1/5-1/20. Accordingly, the average power Pav of a laser beam modulated by such a pulse LP becomes extremely small, and for instance, when the duty of the pulse LP is 10%, even if its peak value power is 10mw, the mean value power can be suppressed to 1mw. In this state, this intermittent modulation laser power is reflected from the disk surface, and when a detecting signal corresponding to a data is detected by a photodetector form a reflected light by which the plane of polarization rotates by a Kerr effect, a signal waveform Sa and Sb are outputted, and by subtracting Sa-Sb, a detecting signal SD is obtained.

Abstract: PURPOSE:To obtain a stable device free from corrosion of an Al electrode by laying an insulation film of 1,000Angstrom  or less on an insulation film on the surface of a semiconductor substrate wherein p-n junction is formed, through the intermediary of a PSG film. CONSTITUTION:On the Si substrate having the p-n junction are laid SiO29, PSG4 and SiO210, among which the film 10 has 1,000Angstrom  or less.

Abstract: PROBLEM TO BE SOLVED: To send data with a broad band to a wireless terminal by generating a broad band CDMA forward channel from two or more sub channels with different frequencies so as to increase a data rate of a CDMA forward channel. SOLUTION: An amplifier stage 405 amplifies each carrier modulated by plural forward channel transmitter-receiver sets 403. Each of plural adders 701 of the amplifiers 405 receives the carrier modulated by each transmitter- receiver 403 to produce a synthesis signal, each amplifier 703 amplifies it and gives the amplified signal to an antenna array. In the case that the transmitter- receiver 403 is set to an IS-95 compatible mode, only one signal of a forward channel is sent from one antenna in the antenna array. In the case that the transmitter-receiver 403 is set not to the compatible mode but to a broad band mode, the transmitter-receiver 403 produces 2 derivative data streams or over, modulates different carrier frequencies by them and the result is sent from the other antenna in the antenna array. Thus, the spectrum efficiency and the traffic capacity of each base station are enhanced.
