Title: Multiplex communication apparatus using spread spectrum
Inventor: MORIFUJI TOSHIAKI
IPC: H04J13/00
Filed: 1999-08-05
Abstract: PROBLEM TO BE SOLVED: To obtain a stable correlation output with a receiver and to perform multiplex communication using spread spectrum by outputting baseband data stabilizing a correlation output most in a receiving side in accordance with a combination of transmission data. SOLUTION: This apparatus comprises three I/Q dividers 1 dividing transmission data, a memory 2 outputting data corresponding to the divided data to a D/A converter 3, the D/A converter 3 and an orthogonal modulator 4. The memory 2 stores a multiplexed spread signal value which corresponds to the divided data, i.e., 18 bits and also prevents the fluctuation of an output of a correlation detector in a receiver side. The multiplexed spread signal value is outputted from a transmitter through the converter 3 and the modulator 4. Such a transmitter preliminarily prepares baseband data which stabilizes a correlation output most in the receiving side to a combination of the transmission data and outputs the baseband data in accordance with the combination of the transmission data.

Title: Beam vibration controlling structure

Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of the worst situation by furnishing an opening through removal of a web in the central part of a beam, admitting a shearing deformation of the opening caused by a horizontal force of earthquake, and allowing a damper and a lever to absorb the seismic energy by their deformation. SOLUTION: The web 2 in the central part of a beam is removed and an opening 10 is provided. The base end is supported by flanges 3' remaining over and under the opening 10 and the tip 31 of a lever 30 is coupled with a damper 20. With a seismic input a relative displacement is generated in the end parts of the beam, and the opening 10 with sunk rigidity goes in a shearing deformation. In the case of fine tremor of earthquake, the lever 30 moves in linkage with the flanges 3' to cause deformation of a viscoelastic damper 20 to result in damping of the deformation stroke of the opening 10. In the case of a small/medium size of earthquake, the lever 30 is deformed elastoplastically to result in damping of the deformation stroke of the opening 10.  In the case of large earthquake, the top surfaces of stoppers collide with each other to restrict further shearing deformation of the opening 10, so that the opening 10 pill not crush but the two ends of the beam yield to absorb the vibratory energy.

Abstract: PURPOSE:To mix the first circuit element group consisting of a transistor of high hFE and low breakdown strength and the second circuit element group consisting of a transistor of low hFE and high breakdown strength within the same semiconductor chip by mutually varying the impurity diffusion depths in the base regions of transistors. CONSTITUTION:When forming the emitter region 5b of a transistor 5, a little N-type impurities are diffused only to the emitter region 5b, and then N-type impurities are diffused to each emitter region 5b and 6b of transistors 5 and 6 in the same process so as to form the emitter region 5b deeper than the emitter region 6b. Doing it so, the width W2 of a base region 5a becomes narrower than the width W1 of a base region 6a, while, since in general the narrower the base region becomes, the higher the hFE of the transistor becomes, the hFE of the transistor 5 becomes higher than the transistor 6.

Title: Production of substrate for magnetic recording medium
Inventor: MURAKAMI SHIRO
IPC: G11B5/84
Filed: 1988-09-07
Abstract: PURPOSE:To prevent the generation of deformation and crack by providing an underlying layer of an alumite base having 250 to 400 hardness Hv on the surface of a substrate and subjecting this underlying layer to a sealing treatment. CONSTITUTION:The substrate consisting of an aluminum or aluminum-based alloy is immersed in a chromic acid soln. and is subjected to an anodic oxidation treatment to provide the underlying layer of the alumite type having 250 to 400 hardness Hv on the surface of the substrate. This underlying layer is subjected to the sealing treatment. The hardness at the time of forming the underlying layer of the alumite type is low in this case and, therefore, the generation of the crack by heating is prevented even if the heat treatment is executed during the production process. Since the restraining force of the substrate by the underlying layer is small, the deformation of the substrate is lessened.

Title: Rotor for induction motor
Inventor: MIYAZAKI MITSUHIRO
IPC: H02K9/06
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To inexpensively obtain a highly efficient induction motor which has a heat radiating property and a cooling property and is less in secondary resistance loss, by providing a plurality of conductor bars composed of copper or a copper alloy to the rotor of the motor in such a way that the bars are protruded from the end faces of the end rings of the rotor. SOLUTION: Plurality of conductor bars 9a are respectively protruded from the end faces of end rings 10 on both sides of a rotor 4a. Consequently, a highly efficient induction motor can be realized at a low cost, because the heat radiating property of its rotor and the cooling property of its stator are improved. Although the conductor bars 9a are protruded at regular intervals from both sides of the rotor 4a in this example, the bars 9a can be protruded from one side only. In addition, although there is no restriction on the number and protruded positions of the bars 9a so long as a plurality of bars 9a is protruded, it is needless to say that the regular intervals are better when the balance is taken into consideration.  When pluralities of long conductor bars 9a made of copper of a copper alloy are respectively protruded from the end faces of the end rings 10 of the rotor 4a in such a way, a highly efficient induction motor which has a heat radiating property and a cooling property and is less in secondary resistance loss can be realized inexpensively without adding any other parts.
