Title: Tdma mobile radio equipment
Inventor: TARUSAWA YOSHIAKI
IPC: H04J3/00
Filed: 1993-01-14
Abstract: PURPOSE:To miniaturize an antenna sharing device by providing a control signal generating means on a TDMA(time division multiple access) control circuit to turn on a reception power switch only in a reception state and also to turn on a transmission power switch only in a transmission state respectively. CONSTITUTION:A transmission power switch 31 and a reception power switch 32 are provided between a power supply 27 and the power terminals of a transmission circuit 16 and a transmission circuit 11 respectively. A TDMA control circuit 21 generates the transmission and reception circuit power control signals for drive of both switches 31 and 32. Then these switches 31 and 32 are turned on only in a transmission state and a reception states respectively. Therefore the levels of noises of a reception frequency generated from a power amplifier circuit 19 are reduced at the time of reception. Meanwhile the levels of undesired waves produced from a low noise amplifier circuit 12 are reduced at the transmission. Thus it is possible to reduce the attenuation factors out of a normal band for a transmission filter 25 and a reception filter 26 which are contained in an antenna sharing device 23.

The filter circuit is composed of plural serial resonance circuits which are connected parallel, the resonance frequencies of the respective serial resonance circuits are gradually made different, and the band width of two resonance circuits having the adjacent resonance frequencies is partially overlapped each other. By connecting such a filter circuit between one point on the signal transmission line and the ground line, this filter circuit is operated as a band stop filter. This filter circuit is a double terminal type filter, and the miniaturization and high-density mounting of a filter component can be realized.

Title: Knocking control device for engine
Inventor: IKEURA KENJI
IPC: F02P5/153
Filed: 1990-01-12
Abstract: PURPOSE:To perform control without exceeding the limit of the knocking level by determining the correlation function between the pseudo irregular signal superposed on the ignition timing signal and the knocking signal, and correcting the ignition timing so that it coincides with the target value. CONSTITUTION:The degree of the knocking level generated in an engine is grasped by the mutual correlation function phixy(alpha) between the M-series signal (x) finely changing the ignition timing and the knocking signal (y). When the value of phixy(alpha) exceeds the target value Rs set as a value near the knocking limit, the ignition timing is delayed by the correction quantity HOS, on the contrary when the value of phixy(alpha) is smaller than Rs, the ignition timing is advanced by the correction quantity HOS. The actual knocking level is controlled to the target value set near the knocking limit, and control precision can be improved without exceeding the knocking limit.

Filed: 1990-01-13
Abstract: PURPOSE:To reduce the discharge amount of CO2 by spraying mist-like limewater to CO2 in the exhaust gas discharged from a combustion chamber to change CO2 to CaCO3 and water. CONSTITUTION:The exhaust gas containing CO2 discharged from a combustion chamber 2 where a carbon compound is burnt is guided to an exhaust pipe 1 through a pipe 3.

Abstract: PURPOSE:To produce dense magnesium hydroxide having large particle diameter and high sphericity, by reacting a water-soluble magnesium salt with ammonia under specific condition, agglomerating a part of the particles, and crystallizing the secondary particles having definite particle diameter and specific surface area. CONSTITUTION:Ammonia gas is introduced into an aqueous solution of a water- soluble magnesium salt such as magnesium chloride to crystallize the crystal of magnesium hydroxide. The crystallization load of the magnesium hydroxide in the above process is adjusted preferably to <=500kg/m<2>.h, and the concentra tion of the magnesium hydroxide slurry in the crystallizer is made to be 1-6wt%. The primary particles are agglomerated to form secondary particles of magnesium hydroxide in a nearly spherical form with an average particle diameter of 5-500mu and a specific surface area of 25-1m<2>/g. Since the particle is composed of a number of flaky primary particles collected along various directions orienting the flakes almost radially from the center toward the out side, the produced secondary particle takes a spherical form in appearance.
